1 INTRODUCTION The UPS is the type “ON LINE DOUBLE

CONVERSION” and is connected between main power and user loads (see picture 1). As far as architecture and layout is concerned, this project is optimised with particular care in order to make it suitable for applications where reliability and high performances are fundamental for critical loads.

The UPS operation is optimised by microprocessor digital control and the IGBT inverter is based on a high frequency PWM waveform.

The UPS operation is controlled by two DSP 16-bit microprocessors, one for the rectifier and one for the inverter. The control logics are interfaced to a microprocessor-based LCD panel, which can be easily programmed by means of a control software to modify the LED signalisations and the alarms available on the relay cards.

Procedures for power-on, power-off, switching to and from bypass are described step by step on LCD display, in order to help the users to easily operate the UPS.

Results of electrical measurement, alarm, work condition, event log and battery status are displayed real time on the LCD front panel.

Picture 1 – UPS block diagram

With this configuration UPS guarantees high quality output, needed by loads requiring a stable and clean source of power. The main features are:

• Protection for black-out, in the limits of battery autonomy

• Complete filtering of main power noise • High quality output power, provided under

any condition of input power and loads • Stable output frequency, independent from

input frequency • Full compatibility with every type of load • Configurable with any neutral wire

configuration (under request) • Automatic control of battery, during both

charging and discharging phases • Easy to interface with user devices • Auto-diagnostic feature and

troubleshooting support • Flexibility of complete bypass configuration • Full access from the front and from the roof

for maintenance

The block diagram shows the UPS subsystem that will be analysed in the following chapters:

• Rectifier/Battery Charger (R) • Inverter (I) • Battery (B) • Static switch: Static inverter switch (SSI)

and Static Bypass switch (SB) • Manual Bypass (MB)

2 GENERAL DESCRIPTION 2.1 RECTIFIER BATTERY CHARGER

The rectifier converts the alternate voltage at the input, with frequency and amplitude variable according to the Technical Specification (ST), into a continuous output voltage that is stabilized in voltage and controlled in current, by means of a three-phase SCR rectifier bridge (6 pulses version) or a couple of bridges connected in parallel (12 pulses version).

The galvanic isolation of the input mains (when required by the ST) is carried out by means of a transformer. Additional protection against power surges, under and over voltage are included as a standard. Optionally a grounded screen between the primary and secondary windings and semiconductor fast transient protection devices (varistors) can be provided.

A programmable soft-start, reducing the inrush current of the rectifier during the start up, is included as a standard.

In “Manual Regulation” mode it is possible to set the output rectifier voltage by means of external potentiometers. In this modality a maximum current limitation (to be set) is also active.

The transfer command “AUTOMATIC/MANUAL” and vice-versa is activated by means of a selector on the front panel; it is also possible to carry out the same command through the remote PC.

The system can be interfaced with similar equipment through a digital link for parallel operation with equal sharing of the load (+/-5% tolerance) and automatic exclusion of the faulty unit.

Picture 2 – Rectifier

2.1.1 Automatic recharge of the battery When selected the rectifier recharges the

battery automatically, according to the predefined

UPS General data

modalities. The recharging cycle begins consequently according to one of the following events (which are programmable):

- Mains failure for a period longer than the programmed value

- Intervention of the current threshold. - Intervention of the voltage threshold. - Timed boost charge The predefined cycles can be programmed in

the Menu Parameters. 2.1.1.1 Recharge IU according to the DIN

41773 standard The recharge is divided in two different

phases: - Phase 1: the current is constant and the

voltage increases. - Phase 2: the current decreases and the

voltage is constant. When the recharging current goes below a

certain value the battery is assumed fully recharged and the cycle ends. Consequently the output voltage is set at the floating level. During the floating the battery voltage is controlled as minimum value in order to avoid undesirable discharges, and as maximum value in order to avoid excessive heating of the electrolyte. The “thermal compensation” of the floating voltage in function of the battery temperature can be added as an option.

Picture 3 – IU recharge

2.1.1.2 I1 I2 U recharge This recharge is used mainly for Ni-Cd

batteries. During the recharge a boost charge of approx. 125% is provided, to compensate the losses in discharge and recharge of the battery (estimated in approx. 25%). The recharge works as follows:

If the mains fails for a time longer than the programmable threshold, when the mains returns the output voltage of the rectifier switches to a level higher than the floating, called boost charge and a safety timer is activated. If the recharging current exceeds the programmed threshold, normally a certain percent of C10, the voltage is maintained and a first phase of boost charge

starts, where the current is constant and the voltage is increasing.

After a certain time the current starts to decrease and the voltage remains constant at the boost charge level. This is the second phase of the boost charge. Finally, when the current go down below the programmed level for the return in floating, the output voltage of the rectifier is taken back to floating. If this does not happen within the max. programmed time, the safety timer blocks the charge and the voltage is forced to floating. This event generates an alarm.

Picture 4 – I1 I2 U recharge

2.1.1.3 U1 U2 I recharge This recharge is used mainly for Ni-Cd


If the mains fails for a time which is longer than the programmable threshold, when the mains returns the output voltage of the rectifier switches to a level higher than the floating, called boost charge and a safety timer is activated.

If the recharging voltage doesn’t exceed the programmed crossing threshold, normally a certain percent of the floating, the voltage is maintained and a first phase of boost charge starts, where the current is constant and the voltage is increasing.

After a certain time the recharging voltage reaches the programmed level for the second phase of boost charge; a timer is started and the battery is kept under boost charge conditions for the time programmed. After this time has elapsed the output voltage of the rectifier is switched back to the floating value. If this does not happen within the maximum programmed time, the safety timer block the charge and the voltage is forced to floating. This event generates an alarm.

Picture 5 – U1 U2 I recharge

2.1.2 Timed boost charge This recharge is used mainly for Ni-Cd


If the mains fails for a time longer than the programmable threshold, when the mains returns the output voltage of the rectifier switches to a level higher than the floating, called boost charge for a pre-programmed time. The boost charge command can also be associated to an external command.

Picture 6 – Timed recharge

2.1.3 Manual recharge The manual recharge of the battery, called

also of forming or of equalizing is a function offered by the RCN that allows the operator to carry out a recharge under his own manual control. This modality of recharge can be used to form the battery after that it has been stocked for a long period, or after that the electrolyte has been filled up, in the case of batteries having been shipped dry, or in order to equalize the voltage of the battery cells after having been used for a certain period.

The manual recharge procedure is described in detail in the relevant menu of the FRONT PANEL chapter of the Operating Manual. Generally, when manual recharge is selected it is possible to change manually the output voltage by means of a potentiometer to vary the recharging battery current. Such current is however always limited to a pre-selectable maximum value.

2.2 INVERTER The DC voltage is converted by the IGBT

bridge, that uses four switches, controlled using PWM (Pulse Width Modulation) technology at high commutation frequency. The PWM generation as well as the control of the operating variables is completely managed by the microprocessor.

The DC current transducer CT provides for the monitoring of the inverter input current. Its feedback signal is managed by the microprocessor to activate the output short circuit current limitation (see 2.2.3) and the IGBT protection (see 2.2.4).

Picture 7 – Inverter

The output transformer provides the galvanic insulation between DC and AC side, as well as voltage adaptation. Its integrated inductance forms, together with the AC capacitors, a low-pass filter that provides to eliminate the high frequency ripple and keeps the total harmonic distortion of the inverter waveform (THD) lower than 2% (with linear load).

The inverter, thanks to its manufacturing technology and to the microprocessor control, is able to supply indifferently inductive or capacitive loads. The maximum apparent power varies slightly in case the load is highly capacitive (p.f. < 0,9) and a de-rating factor, according to the picture 5, must be applied. The data “100% kW” indicates the maximum active power that the UPS can supply to a resistive load (ex: for a 20kVA UPS Pmax=16kW).

Picture 8 – Diagram of the power

2.2.1 Operation with non-linear load A non-linear load is characterized by a high

peak current versus its RMS value, that in normal condition would introduce a distortion on the output waveform.

The inverter is provided with an instantaneous voltage correction facility, completely managed

UPS General data

6 of 23 JUD410382 Rev. A 23/12/08

by the microprocessor, that provides to vary the PWM generation according to the actual output waveform, in order to keep the THD within 5% even with loads having crest factor equal to 3.

Picture 9 – Operation with non-linear load

2.2.2 Overload management Inverter can provide continuously 100% of

nominal load and can tolerate overload conditions up to 125% for 10 minutes or 150% for 1 minute.

Peak conditions such as take-off of engines or magnetic parts are managed limiting the output current to 200% for 5 cycles, than reducing to 125%.

Any times output power grows above 100% the inverter keeps feeding the loads, while the microprocessor activates the “thermal image” algorithm (technical figure) to calculate thermal image based on output current and duration of the overload in function of the time.

User loads are powered by inverter output up to the end of maximum allowed time, and then the static bypass switches to emergency line without interruption of output power.

Picture 10 – Thermal image characteristic

2.2.2.1 Overload with Bypass available

Picture 11 – Overload with bypass available

As soon as an overload is detected the algorithm starts to calculate the increment of the energy. When the limit is reached the load is transferred to bypass.

To allow a safe cooling of the inverter power components (IGBT’s, transformer) the inverter is switched off for 30 minutes.

When this time has elapsed the inverter is switched on again and the load transferred back to the primary supply. 2.2.2.2 Overload with Bypass NOT available

Picture 12 – Overload with bypass not available

As soon as an overload is detected the algorithm starts to calculate the increment of the energy. When the limit is reached the inverter is switched off to avoid severe damages to the power components.

As soon as the bypass is available again the load is supplied by the bypass static switch.

After 30 minutes the inverter is switched on again and the load re-supplied.

WARNING: this operation causes the loss of

the supply to the load 2.2.3 Short circuit operation

As soon as an output short circuit is detected (alarm A25) the load is transferred immediately to the emergency line that provides to eliminate the fault thanks to its higher short circuit current.

UPS General data

Rev. A 23/12/08 JUD410382 7 of 23

In case the bypass is not available the inverter reduces its output voltage and limits its output current to 200% for 100ms, and then to 125% for 5 seconds, after that it’s switched off (according to EN 62040-3 / EN 50091-3).

Picture 13 – Short circuit characteristic (By-pass not available)

2.2.4 IGBT bridge protection The inverter current is monitored by the DC

current transducer connected upstream the inverter bridge. Therefore the control logic is able to distinguish an output short circuit from an IGBT short circuit.

The behaviour of the inverter in case of short circuit on the load has been described at 2.2.3; the output current is limited and the IGBT bridge current doesn’t reach the protection threshold.

In case of short circuit in the inverter bridge the DC input current increases immediately and there’s no possibility of limitation but stopping the PWM.

In this case the alarm A24 – Current stop is activated and must be reset manually after having verified the status of the semiconductors.

Picture 14 – IGBT bridge protection

2.3 STATIC SWITCH Static switch is based on power

semiconductor (thyristors), rated to work continuously at 150% of nominal output power.

The thyristor connected to the main power is protected by a fast-acting fuse.

Picture 15 – Static switch and Manual by-pass

Thanks to the transfer logic integrated in the control, the load is supplied by the bypass static switch even in case of microprocessor failure.

Overload capability: 150% continuously 200% for 1 minute 2000% for 1 cycle

2.3.1 Inverter Emergency Line transfer The transfer (in less than ¼ cycle) is activated

only if emergency line is in tolerance, for the following reasons:

• Output short circuit • Fault of the inverter • DC over-voltage or under-voltage (inverter

OFF) • Over-temperature • Thermal image shutdown • Forced commutation by “BYPASS

SWITCH” 2.3.2 Emergency Line Inverter transfer

As soon as inverter is correctly working and synchronized, the unit automatically switches to inverter in less than 1 msec. If the system switches back and forth more than 6 times in two minutes, an alarm is generated to inform the user, and the load is blocked to emergency line until a manual reset will clear the faulty condition. 2.4 MANUAL BY-PASS

In order to allow safe maintenance and repair of the unit, the inverter is provided with a manual bypass switch.

In bypass mode all the repair and test activities to verify the efficiency of the whole unit can be carried out safely. Manual by-pass can be inserted by following the relevant instructions. During manual by-pass operation there’s no interruption of the supply to the load.

3 OPERATING MODES 3.1 NORMAL OPERATION

During normal operation all the circuit breakers/switches are closed except MBCB (maintenance bypass).

The three-phase input AC voltage feeds the rectifier via the isolation transformer; the rectifier supplies the inverter and compensate mains voltage fluctuations as well as load variation,

UPS General data

8 of 23 JUD410382 Rev. A 23/12/08

maintaining the DC voltage constant. At the same time it provides to keep the battery in stand-by (floating charge or boost charge depending on the type of battery).

The inverter converts the DC voltage into an AC sine-wave, stabilized in voltage and frequency, and provides to supply the load through its static switch SSI.

Picture 16 – Normal Operation

3.2 BATTERY OPERATION In the event of mains failure, or rectifier

failure, the inverter is no longer supplied by the rectifier, so the battery, that is connected to the DC intermediate circuit, is called up immediately and without interruption to supply the load. The battery voltage drops as a function of the magnitude of the discharge current. The voltage drops has no effect on the inverter output voltage since it is kept constant by varying the PWM modulation.

As the battery approaches the discharge limit an alarm is activated. In case the power is restored (even using a diesel generator) before the limit is reached the system switches automatically back to normal operation, if not, the inverter shuts down and the load is transferred to the bypass (bypass operation). If the bypass mains is not available or outside the tolerance range the complete system shuts down as soon as the lowest battery level is reached.

As soon as the power is restored the rectifier charges the battery, and, depending on the depth of the discharge, the charging current is limited by means of the battery current limitation.

Picture 17 – Battery operation

3.3 BYPASS OPERATION Bypass operation may occur for both manual

or automatic change-over. The manual transfer is due to the BYPASS SWITCH, that forces the load to bypass. In the event of a bypass failure

the load is transferred back to inverter without interruption.

Picture 18 – Bypass operation (manual change-over)

The automatic change-over occurs for the reasons explained in the UPS technical description (see paragraph 2.4.1); basically when the power supply to the load within the specified tolerance cannot be assured by the inverter.

Picture 19 – Bypass operation (automatic change-over)

3.4 MANUAL BYPASS The manual bypass operation is necessary

every time the functionality of the UPS needs to be checked or during maintenance or repair works.

The manual bypass procedure is described in the UPS operating manual and must be followed carefully in order to avoid damages to the UPS.

During the functional check of the UPS, all the breakers can be closed, except for the output breaker OCB, and the full functionality can be tested.

Picture 20 – Manual Bypass for functional tests

During the manual bypass operation for repair or maintenance, the UPS is completely switched off and the load is supplied directly by the bypass mains.

4 TECHNICAL CHARACTERISTICS For technical characteristics see the attached

data sheets (chapter 11).

5 PROGRAMMING AND PARAMETER SETTING

The “setting” menu on the front panel allows to adjust the most important operating parameters for the rectifier, inverter and static bypass.

In alternative the programming can be carried out by a PC connected to the serial port RS232 of the front panel, using the dedicated interface software. At the end of the setting the modified parameters must be memorized in the non-volatile memory (EEPROM).

Another software suite, specifically designed for the front panel, allows the programming of the signalization LED’s and alarm relays.

6 ALARMS, STATUS AND SIGNALS

The alphanumeric display offers a complete diagnostic of the system. Each alarm and status is associated to a code; the alarm codes are stored in the events history.

The display management for the alarms and status, including the history log, is described in the chapter FRONT PANEL of the Operating Manual.

7 FRONT PANEL The front panel of the UPS, consisting of a

four-row alphanumeric display plus 15 function keys, allows the complete monitoring of the UPS status.

The power flow diagram helps to understand the operating status of the UPS.

Picture 22 – Front panel

The front panel main functions are: - Show all the relevant input and output

current, voltage and frequency measures - Show all the alarms and status of the UPS - Show the events history The following remote connections are also

available: 1. Through an RS232 protocol 2. Through a ModBus RS485 protocol The relay cards and the signalisations by

LED’s can be programmed by a dedicated software interface.

The front panel can also be set in “transparent” mode to connect a PC to the rectifier or inverter microprocessors in order to check and/or adjust all the operating variables.

8 PARALLEL REDUNDANT OPERATION

The parallel system consists of “n” (up to 4) units, which are equipped like standard units. Only the manual bypass can be external and unique for all the units (on request).

On each inverter one extra PCB (RPI-BUSCAN), that provides the parallel redundant functions, is installed.

In addition to the standard functions as uninterruptible power supply, total power control and protection of the load from mains distortion, the parallel redundant system guarantees an uninterrupted power supply even in case of an internal failure in one of the inverters. This is possible because all units are constantly in operation and feed the load in parallel at “total load / n”, where “n” is the number of the UPS.

The AC automatic current sharing control equalizes the currents of the “n” inverters and reduces the total unbalance to less than 10%, under all load conditions. The load is supplied by the inverters in parallel for an instantaneous overload up to “n x 200%” of the nominal load of a single unit.

In case of failure in one unit, the other units supply the load. The load is supplied by the static bypass only when the redundancy logic, that can be set by a dedicated software program, is no longer satisfied.

Picture 23 – Parallel redundant configuration (double battery)

In case of parallel redundant system with single battery bank (common DC bus) the rectifiers can be equipped with an additional parallel board that controls the current sharing on the DC bus.

In this case the rectifiers are connected by means of a communication cable, through which all the information necessary for the current sharing and the alarms management are exchanged.

UPS General data

Rev. A 23/12/08 JUD410382 11 of 23

During the floating charge each rectifier supplies the 50% of the total load (Active Current Sharing), therefore in case of failure of one unit the load is supplied by the remaining rectifier without affecting the DC bus-bar.

During a mains failure the batteries supply the necessary energy.

The battery charging cycle is automatically started upon the mains return; during the current limitation phase (operation as current generator) the current is completely supplied by the rectifier #1, whereas the rectifier #2 follows the DC bus-bar voltage without supplying any current. In case of failure of the rectifier #1 the load is supplied by the rectifier #2, still operative, without affecting the DC bus-bar. At the end of the current limitation phase the Active Current Sharing control is restored.

In case two batteries are connected to the DC bus-bar the recharge is carried out limiting the battery that absorbs the highest current.

1. INTRODUCTION

1.1 ENVIRONMENT

1.1.1 UPS treatment at the end of service life The UPS manufacturer undertakes to recycle, by certified companies and in

compliance with all applicable regulations, all UPS products recovered at the end of their service life (contact your branch office).

1.1.2 Packing UPS packing materials must be recycled in compliance with all applicable

regulations.

1.1.3 Lead battery This product contains lead-acid batteries. Lead is a dangerous substance for the

environment if it is not correctly recycled by specialised companies. 1.2 SAFETY RULES

1.2.1 Safety of persons The UPS must be installed in a room with restricted access (qualified personnel only,

according to standard EN50091-1-2). UPS power outlets may be energised even if the UPS is disconnected from the AC-

power source (because the UPS is connected to a battery). Dangerous voltage levels are present within the UPS. It should be opened

exclusively by qualified service personnel. Warning, after the UPS shut-down, a dangerous voltage will be present on the

battery circuit breaker BCB. The UPS must be properly earthed. The battery supplied with the UPS contains small amounts of toxic materials.

To avoid accidents, the directives listed below must be observed. ω Never operate the UPS if the ambient temperature and relative humidity are

higher than the levels specified in the documentation. Never burn the battery (risk of explosion). ω Do not attempt to open the battery (the electrolyte is dangerous for the eyes

and skin). ω Comply with all applicable regulations for the disposal of the battery.

1.2.2 Product safety A protection circuit breaker must be installed upstream and be easily accessible. Never install the UPS near liquids or in an excessively damp environment. Never let a liquid or foreign body penetrate inside the UPS. Never block the ventilation grates of the UPS. Never expose the UPS to direct sunlight or a source of heat.


4 of 11 JGE410503 10.12.2008

1.2.3 Special precautions ω The UPS connection instructions contained in this manual must be followed in the

indicated order. ω Check that the indications on the rating plate correspond to your AC-power system

and to the actual electrical consumption of all the equipment to be connected to the UPS.

ω If the UPS must be stored prior to installation, storage must be in a dry place. ω The admissible storage temperature range is -10° C to +70° C. ω If the UPS remains de-energised for a long period, we recommend that you

energise the UPS for a period of 24 hours, at least once every month. This charges the battery, thus avoiding possible irreversible damage.

ω The UPS is designed for normal climatic and environmental operating conditions as defined in the data sheets.

ω Using the UPS within the given limits guarantees its operation, but may affect the service life of certain components, particularly that of the battery and its autonomy. The maximum storage time of the UPS is limited due to the need to recharge its integrated battery.

ω Unusual operating conditions may justify special design or protection measures: - harmful smoke, dust, abrasive dust, - humidity, vapor, salt air, bad weather or dripping, - explosive dust and gas mixture, - extreme temperature variations, - bad ventilation, - conductive or radiant heat from other sources, - strong electromagnetic fields, - radioactive levels higher than those of the natural environment, - fungus, insects, vermin, etc., - battery operating conditions. The UPS must always be installed in compliance with:

- the requirements of HD 384.4.42 S1/A2 - Chapter 42: Protection from

thermal effects. - standard IEC 60364-4-482 - Chapter 482: Fire protection.

The manufacturer declines all responsibility for damages to people or

equipment deriving from non-fulfilment of the above.

2. UPS GENERAL DESCRIPTION

2.1 TYPOLOGY The UPS covered by this manual are on-line, double conversion; the inverter

supplies always energy to the load, whether mains is available or not (according to the battery autonomy time).


10.12.2008 JGE410503 5 of 11

WARNING The UPS output is energized even during mains failure, therefore in compliance with

the prescriptions of EN 50091-1, the installer will have to identify the line or the plugs supplied by the UPS making the User aware of this fact.

This configuration guarantees the best service to the User, as it supplies clean

continuously regulated power and guarantees the voltage and frequency will be stabilised at nominal value independently from mains status. Thanks to the double conversion, it makes the load completely immune from micro-interruptions due to excessive mains variation, and prevents damage to the critical load (Computer - Instrumentation - Scientific equipment etc.).

Picture 1 - Block diagram

2.2 SYSTEM DESCRIPTION

2.2.1 Rectifier It converts the three phase voltage of the mains into continuous DC voltage. It’s designed to supply the inverter at full load and the battery at the maximum

recharge current. The system offers very low ripple content during the charging cycle.

2.2.2 Inverter It converts the continuous voltage coming from the rectifier or from the battery into

alternating voltage stabilized in amplitude and frequency. The inverter uses IGBT technology with a frequency commutation of approximately

10 KHz. The control electronics is completely digital and uses a 16 Bit μP, that, thanks to its

processing capability, generates an excellent output sine-wave, which has a very low distortion even in presence of loads having high crest factor currents.

2.2.3 Battery charger The battery charger control logic is completely integrated inside the total-controlled

rectifier control board; the battery is charged, according to the DIN 41773 Standard, every time it has been partially or completely discharged and it is kept floating, even when it’s charged, to compensate for any autodischarge.

2.2.4 Static bypass It’s designed to transfer the load between INVERTER and MAINS, and vice-versa,

without break, and uses SCR’s as power commutation elements.

2.2.5 Manual bypass It‘s used to by-pass the UPS, supplying the load directly to the mains in case of

maintenance or serious failure.

WARNING The sequence of bypass switching must be carried out with respect to the procedure

indicated on the UPS and in the chapter “Start-up, shut-down and manual bypass”. The manufacturer cannot accept responsibility for damages arising from incorrect operation.

2.2.6 Front panel The front panel of the UPS, consisting of a four row alphanumeric displays plus a

keyboard, allows the complete monitoring of the UPS status and the setting of the parameters.

The mimic diagram helps to understand the operating status of the UPS. For more information see the chapter “FP-AC-UPS FRONT PANEL OPERATING

MANUAL”.

2.3 OPERATING STATUS The following paragraphs show all the possible operating status of the UPS.

2.3.1 Normal operation The inverter is supplied by the rectifier; the load, through the static switch, is supplied

directly by the inverter output.

Picture 2 - Normal operation

2.3.2 Load supplied by bypass due to inverter fault The load is transferred to bypass through the static switch; the transfer is carried out

without interruption.

2.3.3 Rectifier failure or mains failure The inverter is supplied by the battery for the required autonomy time; the load,

through the static switch, is supplied directly by the inverter output.

Picture 4 - Rectifier failure or mains failure

2.3.4 Manual bypass The load is supplied by the mains through the manual bypass; the operator can work

in safety on the UPS to carry out maintenance or repairing operations.

3. INSTALLATION

3.1 RECEIPT OF THE UPS When the UPS is received, please attend immediately to its unpacking and carry-out

an accurate visual check to be sure that the equipment has not been damaged during transport.

IMPORTANT

In case of objections relating to damage incurred during transport these must be immediately notified to the transportation company after receipt of the equipment.

When the UPS is not installed immediately it must be stored carefully in vertical

position, as indicated on the packing and conserved in a dry and sheltered room in its box so that it is protected from dust.

3.2 HANDLING OF THE UPS

Before positioning the UPS, in order to avoid risks of turnover, it’s recommended to move the system on the wood pallet on which the UPS is fixed.

Before the positioning in the final location, remove the UPS from the pallet. The UPS can be lifted and handled using a pallet truck or a forklift after having taken-

off (manually), the lower frontal panel, so that a pallet truck or a forklift can be inserted (see picture 6).

The UPS technical data are shown on a label fixed on the internal side of the front door.

3.3 POSITIONING AND INSTALLATION The UPS must be installed in a clean and dry room, preferably not dusty. The User

must ensure that there is enough air exchange in the room so that the equipment can be adequately cooled; if this is not guaranteed, the room must be adequately aired. 3.4 ELECTRICAL CONNECTION

The electrical connection is part of the work which is normally provided by the supplier that carries out the electrical installation and not by the UPS manufacturer. For this reason, the following recommendations are only an indication, as the UPS manufacturer is not responsible for the electrical installation.

In any case we recommend to carry-out the installation and the electrical connections of the input and output in compliance with the local standards.

During the electrical installation take particular care to check the phase rotation with a suitable instrument.

The terminal boards are positioned at the front of the UPS, under the breakers. To

access the terminals remove the protection, extracting the fixing bolts.

WARNING The connection to the mains must be carried out with protection fuses between the

mains and the UPS. The use of residual current devices in the line supplying the UPS is

unadvisable. The leakage current due to the RFI filters is rather high and it can cause spurious tripping of the protection device.

According to the EN50091-1 standard, in order to take into account the UPS’ leakage current, residual current devices having adjustable threshold can be used.

3.5 BATTERY INSTALLATION

IMPORTANT

For battery installation please respect the prescriptions of the EN50091-1 standard, paragraph 4.5.

To obtain the battery life indicated by the battery manufacturer, the operating temperature must remain between 0 and 25 °C. However, although the battery can operate up to 40 °C , there will be a significant reduction of the battery life.

To avoid the formation of any kind of potentially explosive hydrogen and oxygen mixture, suitable ventilation must be provided where the battery are installed (see EN50091-1 annex N).

It is recommended to install the batteries when the UPS is capable of charging them.

Please remember that, if the battery is not charged for periods over 2-3 months they can be subject to irreparable damage.

1.4 TRANSPARENT MODE

In this mode the panel behaves as if the user itself is connected directly to the unit. (rectifier or inverter depending of the selectors disposition). This enables direct communication with the unit. It is possible to receive the data as well as send commands. 1.5 MODBUS COMMUNICATION

MODBUS is an application layer messaging protocol, positioned at level 7 of the OSI model, that defines the modes of communication between a "master" and one or more "slaves". It is possible to connect one master to up to 247 slave units, using one common bus.

The MODBUS protocol defines: how master and slave establish and interrupt the communication, how to identify receiving and transmitting, how to exchange the messages, and the techniques of error identifying. Only unit identified as master can start the transmitting, which can be "question/answer" based type (with one single slave), or based on a "broadcast" type in which the message is sent to all slave units, but slave units do not send any answer back.

The transmission is set up in RTU mode (Remote Terminal Unit) and the end of the message of request towards one of the devices is identified by 100ms interval, in which no answers are sent back. The question and answers have the following structure:

Slave Address Function Data CRC (Cyclical Redundancy Check)

1 byte 1 byte N byte 2 byte

MODBUS function codes are elements of MODBUS request/reply PDUs (Protocol Data Units).

Communication parameters are the following:

two stop bit parità: none BAUD rate 9600 bit/s RTU format data 8 bit

In order to configure the address (from 1 to 247) the following coman is to be used,

sending it through the serial interface: SET MODBUS ADDRESS. There is also a comand which enquires about the address that was already set: GET MODBUS ADDRESS. Please refer to Apendix "A" in this chapter in order to find futher information about comands.

The software is using the function coded as 03 of the PDU (Holding Register). When

receives this instruction, the panel responds by sending the data table described below:

1. GENERAL The UPS of the “E2001.e” industrial series are on-line, double conversion; the inverter

supplies always energy to the load, whether the mains is available or not (according to the battery autonomy time).

WARNING

The UPS output is energized even during mains failure, therefore in compliance with the prescriptions of EN 50091-1, the installer will have to identify the line or the plugs supplied by the inverter making the User aware of this fact.

This configuration guarantees the best service to the User, as it supplies clean continuously

regulated power and guarantees the voltage and frequency will be stabilised at nominal value independently from mains status. Thanks to the double conversion, it makes the load completely immune from micro-interruptions due to excessive mains variation, and prevents damage to the critical load (Computer - Instrumentation - Scientific equipment etc.).

Picture 1 – UPS block diagram

The UPS is composed by three main sections: rectifier (R), inverter (I), static switch (SS). These sections will be described in the following chapters.

The final chapter includes the description of the various electronic boards installed inside the UPS as well as their block diagrams and programming instructions.

1.1 OPERATING STATUS Final task of a UPS system is to protect the load from micro-interruptions, black-outs and

various disturbances on the network, and guarantee a reliable supply also when internal faults occur. During normal operation the rectifier keeps the batteries in floating charge and provide energy for the inverter to supply the load through the static switch.

Picture 2 – Normal operation



In case of an inverter failure or an overload the load is automatically transferred, without interruption, to the by-pass static switch.

Picture 3 – Load supplied by by-pass

The inverter is the primary supply source, so when its voltage and frequency are in tolerance it synchronises with the by-pass line and the load is transferred again through the static switch.

In case of mains failure (or rectifier failure) the inverter draws energy from the battery for the specified autonomy time, after which the inverter is turned off.

Picture 4 – Rectifier failure or mains failure

For maintenance operations it’s possible to supply the load through the manual by-pass circuit breaker MBCB, connecting directly the by-pass line to the UPS output. During the manual by-pass procedure the load remains supplied, without any interruptions.

Picture 5 – Manual by-pass



2. RECTIFIER The rectifier converts the alternate input voltage having a variable amplitude and frequency

into a constant-voltage and current-controlled direct output power source. Its function is to control the output values via a three-phase fully controlled SCR rectifier bridge (6-pulse version) or via two of these paralleled bridges (12-pulse version).

Galvanic insulation from the input mains (when provided for by the technical specification is achieved via a transformer.

2.1 BASIC STRUCTURE The basic structure of the rectifier is the following: • The input mains crosses the EMI filter for high frequency emissions and gets into the

primary winding of input transformer T1, via isolator RICB. The synchronism signals are taken from the primary winding for the control of the SCR firing

angle, the input currents for the measurement and the supply voltage for the control logic (battery redounded)

• The secondary winding is connected to the SCR bridge via protection fuses.

• In the 12-pulse version, the input transformer has got 2 secondary windings and 2 SCR bridges.

• The control logic, housed in the rack named DR16, consists of the following cards:

BP-DR16 Id. no. N_FS3004 Interconnection panel PS-DR16 Id. no. N_FS3005 ower supply DR16 -COMP Id. no. N_FS3006 Control card (CPU) CAN-LINK Id. no. N_FS3011 Connection card CAN_BUS (optional for

parallel redundant configuration)

• The firing of the SCR’s is controlled by card DR16-COMP, and is performed via card: RTF Id. no. N_FS3002 SCR firing card

• The rectified and controlled voltage is filtered by an L (series inductance) and C

(paralleled capacitors) unit, calculated in accordance with the maximum ripple voltage provided for by the Technical Specification.

• On the output of said unit, a feedback voltage is taken for the voltage control and

measurements are made regarding the total output current (for the total limitation), as well as the charging and discharging current and voltage of the battery, if this function is provided.

• The the rectifier output is connected to the loads via isolator ROCB.



Picture 6 – Rectifier block diagram

2.2 6-PULSE RECTIFIER (STANDARD) The type of standard bridge configuration used by the rectifier is three-phase, fully controlled,

with SCR’s and 6 pulses. It is so sized as to supply direct current loads and to recharge the battery to the maximum charging current provided for by the Technical Specification. The nominal standard value of the current harmonic distortion (THD) reintroduced into the mains by a 6-pulse rectifier is < 27%.

2.3 12-PULSE RECTIFIER (OPTIONAL) The 12-pulse configuration is used to reduce the current harmonic distortion (THD)

reintroduced into the mains, to a value < 12%. This prevents affecting the supply line while respecting the other loads, and avoids the

overheating of cables due to the circulation of harmonics. It consists of two rectifier bridges which, thanks to a phase-shift transformer, operate with 30° difference, eliminating the harmonics typical of 6-pulse bridges, namely the 5th and the 7th harmonic. As a consequence, the harmonics left are the highest ones, namely the 11th, the 13th and multiple ones.



3. INVERTER The inverter is composed by two power blocks, controlled by the IGBT driver boards ID1 and

ID2. The inverter bridge is connected to the transformer T1, which provides the galvanic insulation between the DC bus and the AC output. The transformer is provided with a leakage inductance that forms a low-pass filter with the output capacitor Cr; the filter provides to eliminate the high frequency harmonics from the output waveform in order to reduce the distortion of the sine-wave.

The inverter supplies the load through the inverter static switch thyristor, which is connected to the output switch OCB. The current transformer TA2 provides the signal for the output current measure.

When the inverter is started up the microprocessor control logic I/S-CL generates the IGBT’s control signals (PWM – Pulse Width Modulation) and send them to the driver boards ID1-ID2; the bridge starts to modulate and the output voltage increases. The voltage feedback provided by the INV-AV-1F board is used to control the output voltage value, according to the value set on the VCB board (mounted on the I/S-CL).

The inverter current protection (Max Current Stop) and the short circuit current limitation are also managed by the I/S-CL, using the feedback signal provided by the hall-effect current transducer TA1, which is mounted on the inverter bridge input.

4. STATIC SWITCH The single-phase emergency line is connected to the input terminals 2-L1, 2-N. The filter

RF2 provides to reduce the radio frequency disturbances according to the limits given by the EN50091-2 standard.

The by-pass line is energized by closing the input switch SBCB; the fuse protects the static switch thyristor in case of short-circuit at the UPS output.

The static by-pass switch is controlled by the SCB board, installed on the microprocessor control logic I/S-CL; the control signals for the thyristors are generated by the I/S-CL and sent to the firing board SCRSF-1F or 2SCR-FIR, connected directly to the gate of the thyristors.

The VOLT-REF-1F board provides the feedback signals for the by-pass and output voltage measures.

The UPS automatically transfers the load to the by-pass line in case of an inverter failure or overload. The manual by-pass circuit switch MBCB connects directly the emergency line input to the load in case of UPS maintenance.

Picture 16 – Card DR16-COMP: SCR firing

Integrated circuits U62, U32, U33 are the firing latches that allow to switch the firing pulses to the two bridges.



6. INVERTER AND STATIC SWITCH PCB’S

6.1 ID / DR-SAT – (IGBT DRIVER) The IGBT’s driver cards are used to transfer the turn-on signals created by the

microprocessor card I/S-CL to the IGBT. The drivers draw the power from a 40kHz square wave coming from the POWER SUPPLY

card; the square wave is properly isolated, rectified and filtered and made controllable by a green LED.

The turn-on command for the IGBT’s coming from the card I/S-CL is isolated by an opto-coupler and then slightly integrated through a low-pass filter (dead-time). The final amplifying circuit, using MOSFET’s, provides to translate the modulation signal between +15V (ON Level) and -15V (OFF Level).

The card ID is designed to control a complete bridge leg (positive and negative IGBT’s), the card DR-SAT can only control a single switch, generally made by two IGBT’s in parallel. In addition, the card DR-SAT is provided with a de-saturation sensor which provide to stop the modulation in case the Collector-Emitter voltage exceed the rated IGBT’s saturation value.

6.2 PS-LV / PS-MV / PS-SAT – (POWER SUPPLY) These boards provide the different power supplies to all the sections of the I/S-CL

(microprocessor board) and to the front panel. They take the power at the inverter input and their input voltage range is as follows.

6.3 PWM-SAT – (IGBT DRIVERS INTERFACE) The card PWM-SAT is used only together with the IGBT driver DR-SAT. The turn-on signals

for the IGBT’s are available on the connectors CN7 and CN1 of the microprocessor card I/S-CL, respectively for the first and the second bridge leg.

The driver card DR-SAT can only control one switch, so two of them are necessary for each bridge leg, and the control signals must be different.

The card PWM-SAT is the interface between the I/S-CL and the driver cards DR-SAT that provides to split the turn-on signals and distribute them to the right driver cards.

6.4 INV-AV-1F – (INVERTER VOLTAGE FEEDBACK) The INV-AV-1F provides the inverter voltage feedback for the real-time control loop. The

inverter output phase and neutral, taken on the filter capacitor Cr, are connected on CN1 pin 1 and 7 respectively; the voltage value is reduced by the transformer T1 and sent to the microprocessor control logic I/S-CL via the connector W18.

The UPS output current transformer T20 is connected to CN3 pin 1 and 2; the current generated by T20 flows through the resistor R4, generating a voltage drop proportional to the UPS output current; this waveform is sent to the I/S-CL measuring section for the output current reading.

6.5 VOLT-REF-1F – (BYP / OUT VOLTAGE FEEDBACK) The VOLT-REF-1F provides the signals for the by-pass line and output voltage

measurement. The by-pass is connected on CN1 pin 1 (phase) and 7 (neutral) and supplies the double-secondary transformer T1; a secondary winding, via the single-phase Graetz bridge formed by the diodes D1-D2-D4-D5 and the stabilizer U1, creates a +5V supply that is sent to the I/S-CL board via the connector CN3. This is a redundant supply for the static switch control logic (SCB board) and its presence can be verified by checking the status of the LED DL1. The other secondary winding is used to send the microprocessor, for measuring purposes, a waveform proportional to the by-pass voltage value, via the connector CN4, pin 1 and 4.

The UPS output is connected on CN5 pin 1 (phase) and 7 (neutral) and supplies the double-secondary transformer T2; a secondary winding is connected to the single-phase Graetz bridge formed by the diodes D8-D9-D11-D12, which output is connected in parallel to the stabilizer U1. The other secondary winding is used to send the microprocessor, for measuring purposes, a waveform proportional to the output voltage value, via the connector CN4, pin 5 and 8.

The fuses FU1-FU2-FU3 are used for the fans protection.

6.6 SCRSF-1F / 2SCR-FIR – (THYRISTORS FIRING) The SCRSF-1F and the 2SCR-FIR are the thyristors firing boards and are installed directly

on the static switch thyristors. The control signals generated by the I/S-CL are connected to the card, isolated by high frequency transformers and sent directly to the thyristors. The green (or red) LED’s show which component is controlled, indicating which line is supplying the load.

The card SCRSF-1F is a double firing card, so it can control two pairs of thyristors, that’s to say the whole single-phase static switch.

The card 2SCR-Fir can only control one pair of thyristors, so two of them are necessary for a complete single-phase static switch.

6.7 I/S-CL (MICROPROCESSOR CONTROL LOGIC) 6.7.1 Introduction

The I/S Control Logic (I/S CL) controls all the inverter functions and signals. It takes the digital inputs (like auxiliary contacts, switches and so on), performs all the analog measures (like voltages, currents and so on) and provides the total control of the UPS.



6.7.2 Digital Inputs The digital inputs are connected to the I/S CL via the M3 connector according to the

description on the block diagram. All these signals are de-coupled and latched before they are connected to the microprocessor bus.

6.7.3 Dip Switches The dip switches SW1 and SW2 are connected to the microprocessor bus via the latches

U67 and U68. The functions of the IMN can be programmed as follows.

6.7.4 Fast Analog Inputs The measures of the bypass L1, L2 and L3 phases and output L1, L2 and L3, are directly

connected to the microprocessor A/D converter. The measures can be found in the following points (see picture 11):

6.7.5 Watchdog and Reset The microprocessor is controlled by a smart watchdog system that provides an automatic

reset in case of an error of the microprocessor during the normal operation or a problem in the microprocessor power supply (under-voltage lockout). It is also possible to reset manually the microprocessor by pressing the reset push-button SW3.

6.7.6 RAM, EPROM’s and EEPROM The EEPROM U71 contains the functional parameters of the UPS and the adjustments. The RAM U58 contains the history of the alarms of the UPS. Up to 900 events can be stored

in this device and the backup battery allows to preserve the information for three days after the power has been removed.

The two EPROM’s contain: U55 Program odd addresses U65 Program even addresses.

6.7.7 Digital Power Supply The digital part of the I/S CL has its own power supply (5 volts). This voltage can be checked

on the LED D69 (green) and measured between U75 pin 2 (ground) and pin 3.

6.7.8 RCB board The RCB is an additional card which is fixed on the I/S-CL. It contains the drivers for the

digital outputs of the microprocessor. Each output is de-coupled and buffered on this card. The RCB contains also the RS232 and RS485 drivers for the communication.

6.7.9 SCB board and Thyristor drivers The SCB is an additional card which is fixed on the I/S-CL. It contains the decisional logic for

both bypass and inverter static switches. It can drive directly the bypass static switch or send the command to the I/S-CL to close the inverter static switch.

This card can be programmed through the jumpers J1÷J8 (see picture 12) and it is powered directly by the emergency line at +5V (see par. 4.5.1). This supply can be checked on the LED L1 (green) and measured between U11 pin 10 (ground) and pin 20.

6.7.10 Current Limitation and Max Current Stop The current flowing in the inverter bridge is measured through a hall-effect current transducer

on the M1 pin 2. The maximum current level for the inverter stop (desaturation) can be programmed by

closing the jumpers J9, J10 and J100. These jumpers must be programmed on each unit according to the indications given in the table below. As the maximum current stop comparator commutates the LED D3 red becomes on, the inverter is stopped and the current stop signal is sent to the microprocessor (alarm A24 - Current Stop).

The inverter can be reset by pressing the reset push-button SW4. This protection works in case of a fault or wrong operation on the unit.

Normally the inverter output current is controlled by the current limitation block. The current can be checked on the test point TP2 and the limitation level can be adjusted by turning the



potentiometer P2 on the I/S-CL (see the IMN Test Procedure). As the output current exceeds the limitation value the short circuit detector sends the short circuit signal to the microprocessor (alarm A25 - Short Circuit).

6.7.11 VCB board The VCB is an additional card which is fixed on the I/S-CL. It contains the sine-wave

generator which converts the digital samples of the sine-wave coming from the microprocessor into an analog signal which is transferred to the PWM generator (see below). This card can be programmed by the J1 to work in manual control, (in this case the inverter output voltage can be controlled manually by turning the potentiometer P1 on the I/S-CL) or in closed loop control (in this case the inverter output voltage can be set by turning the potentiometer P1 on the VCB and it is kept the same in all the conditions by the control loop). It is also possible to include or exclude the instantaneous value loop by adding or removing the jumper J2 (see picture 13). This card also sends the measure of the inverter output voltage to the microprocessor via the external A/D Converter (see 4.7.1.13).

6.7.12 PWM generator The I/S control logic can be used to generate both single-phase and three-phase output

voltages. This function can be programmed by setting the jumper J1 on the I/S-CL. For single-phase units only one VCB card must be installed, whilst three VCB cards are used for the three-phase units.

The PWM generator compares the sine-waves coming from the VCB card with a triangular waveform at the switching frequency (U17 pin 6) to generate the PWM modulation to control the inverter power bridge.



6.7.13 External A/D Converter Several analog measures are sent to the microprocessor via the external A/D converter U22.

These measures can be found in the following points:

1 INTRODUCTION This troubleshooting includes a first level fault description starting from the E2001.E alarms

provided by the front panel and suggests how to check the unit to solve the problems. This description assumes that all the connections inside the unit are correct: check them (connectors, power cables, signals and so on) before to start with the procedures. The first level troubleshooting consists of substituting the components of the E2001.E without attempting to repair them.

NOTE All the technical descriptions that follow refers to inverter systems installing the software

release I180STD or following

1.1 CONNECTION OF THE TEST SOFTWARE The UPS is provided of a interface card with both RS232 and USB port, so the connection

between the UPS and the different software programs (test or panel programming) can be performed either using RS232 or USB standard cables.

The front panel is provided with a configuration dip-switch S1 (see picture 1) which enables different types of communication interfaces according to the position of the switches.

CONFIGURAZIONE Dip 1 Dip 2 Communication mode

OFF OFF Programming / Configuration OFF ON Normal mode / SNMP interface ON OFF Rectifier CPU ON ON Inverter CPU

When the troubleshooting procedure asks to “connect the rectifier test software DR16-Test”,

it means that the position of the switches 1-2 of S1 must allow the communication with the rectifier CPU (1-ON, 2-OFF).

When the troubleshooting procedure asks to “connect the inverter test software UPSTest”, it means that the position of the switches 1-2 of S1 must allow the communication with the inverter CPU (1-ON, 2-ON).

2 TROUBLESHOOTING PROCEDURES

2.1 A1 – MAINS FAULT This alarm normally indicates that there is no power at the input of the UPS. The mains

voltage is acquired on the connector M1 of the back panel card BP-DR16 (N_FS3004) through the auxiliary transformer T10.

2.1.1 Troubleshooting procedure 1. Is the input voltage present and within the tolerance?

YES: go to step #2 NO: check the rectifier supply line

2. Measure the rectifier input voltage and compare the measure with the reading on the

DR16-Test screen (or front panel). Are the values shown equal to those measured? YES: go to step #6 NO: go to step #3

3. Check the fuses F11. Is there any fuse blown? YES: replace the broken fuse(s) NO: go to step #4

4. Check the auxiliary transformer T10 by measuring the secondary voltages directly on the transformer terminals. Do the voltage values match the transformer rating plate? YES: replace the card PS-DR16. Go to step #5 NO: replace the transformer T10

5. Is the problem solver after replacing the card PS-DR16? YES: END NO: replace the card DR-16

6. Is the variable RMSOK active on the DR16-Test software? YES: go to step #7 NO: check the phase sequence

7. Is the variable FROK active on the DR16-Test software? YES: replace the card DR-16 NO: go to step #8

8. Measure the rectifier input frequency. Is it within the tolerance limits? YES: replace the card DR-16 NO: check and/or adjust the input frequency window

2.2 A2 – RECT BLOWN FUSES This alarm normally indicates that there is at least one rectifier input fuse blown. The normally closed contact of the fuses is connected to the connector M18 (13-14) of the

back panel card BP-DR16 (N_FS3004). For the 12-pulse configuration the contact of the protection fuses of the slave bridge is connected to the connector M18 (9-10).

2.2.1 Troubleshooting procedure 1. Check the rectifier input fuses. Are they OK?

YES: go to step #2 NO: replace the broken fuse(s)


REV.A JSE411881 08/06/09 JUD411299 7 of 31

2. Check the connection between the auxiliary contact of the fuses and the connector M18 of the card BP-DR16. Is it OK? YES: replace the card DR-16 NO: re-connect or replace the interconnection cable

2.3 A3 – RECT HIGH TEMPERATURE This alarm indicates that the thermal switch on the bridge heatsink has stopped the rectifier.

The thermal switch(es) TH1 (TH1÷TH3) mounted on the rectifier bridge heatsink(s) is normally closed, as the temperature exceeds 90°C the thermal switch opens. The signal comes directly from the switch to the connector M18 (11-12) of the back panel card BP-DR16. For the 12-pulse configuration the contact of the thermal switch of the slave bridge is connected to the connector M18 (7-8).

2.3.1 Troubleshooting procedure 1. Is the temperature of the heatsink lower than 80°C?

YES: go to step #2 NO: go to step #4

2. Check the thermal switch contact. Is it OK? YES: go to step #3 NO: replace the faulty thermal switch

3. Check the connection between the thermal switch(es) and the connector M18 of the card BP-DR16. Is it OK? YES: replace the DR-16 NO: re-connect or replace the interconnection cable

4. Are the cooling fans correctly working? YES: check the load. Repeated overloads (alarm A4) have caused the rectifier

overheating NO: replace the faulty fan(s)

2.4 A4 – RECT OVERLOAD / THERMAL IMAGE This alarm normally indicates that the rectifier is overloaded, and after a certain time (basing

on the overload rate) the rectifier is stopped by the thermal image protection (the status “S1-rectifier OK” disappear). The output current transformer measures a current exceeding the nominal output current. The alarm is activated and the microprocessor starts to calculate the energy pulse I2t.

2.22 A22 – BYPASS SWITCH The E2001.E is equipped with a bypass switch that forces the load to bypass. If this switch is

in the Bypass position the alarm A22 is activated and the load is transferred to bypass (see alarm A16 – Bypass feeds load). This signal comes directly from the switch SW1 to the I/S-CL M3 pins 11-12.

2.22.1 Troubleshooting procedure 1. Is the switch in NORMAL position?

YES: go to step #2 NO: END; move it to NORMAL

2. Check the status of the pins 11-12 of M3 in the Card I/S-CL. Is the contact closed? YES: replace the card I/S-CL NO: replace the switch SW1

2.23 A23 – RETRANSFER BLOCKED This alarm indicates that the load is blocked on the emergency line (by-pass) after 6

transfers to by-pass in 2 minutes. Normally it occurs when there are several heavy load steps (like motors starting, printers and so on) in a very short time. In this case, as the current exceeds two times the nominal value, the short circuit monitor (see alarm A25 – Short circuit) transfers automatically the load to by-pass, and after a few seconds the inverter takes back the load. If this situation happens six times in two minutes, the E2001.E protect itself by blocking the load to by-pass and the alarm is activated. This condition can be reset by sending the command RESE000 or by resetting the system from the special menu in the front panel.

2.23.1 Troubleshooting procedure 5. Are there heavy load steps exceeding two times the nominal output current?

YES: check and/or reduce the load NO: go to step #2

the OCB circuit breaker auxiliary contact to the I/S-CL M3 pins 9-10.

2.25.1 Troubleshooting procedure 1. Is the output breaker OCB open?


2. Check the status of the pins 9-10 of M3 in the Card I/S-CL. Is the contact closed? YES: replace the card I/S-CL NO: replace the OCB auxiliary contact

2.26 A26 – MANUAL BYPASS CLOSED This alarm indicates that the manual bypass circuit breaker is closed. This signal comes from

the MBCB circuit breaker auxiliary contact to the I/S-CL M3 pins 13-14. When MBCB is closed together with OCB the electronic protection turn off the inverter

generating the alarm A13.

2.26.1 Troubleshooting procedure 1. Is the manual by-pass breaker MBCB closed?


2. Check the status of the pins 13-14 of M3 in the Card I/S-CL. Is the contact open? YES: replace the card I/S-CL NO: replace the MBCB auxiliary contact

2. Check the status of the pins 5-6 of M3 in the Card I/S-CL. Is the contact closed? YES: replace the card I/S-CL NO: replace EPO push-button

2.28 A28 – THERMAL IMAGE This alarm normally indicates that the thermal protection has stopped the inverter. The output current transformers measure an output current exceeding the nominal output

current (see the alarm A19 – Inverter overload). The microprocessor starts to calculate the energy pulse I2t. As this pulse reaches the 100% the inverter is stopped for 30' and the load is transferred to the bypass.

2.28.1 Troubleshooting procedure 1. Measure the inverter output current and compare the measure with the reading on the

UPSTest screen (or front panel). Are the values shown equal to those measured? YES: go to step #2 NO: replace the card INV-AV-1F and re-adjust the output current reading with the

UPSTest (see chapter JUD411293 – UPS test software for details on the software commands). Go to step #3

2. Is the alarm A19 - Overload present? (The output current exceeds the UPS nominal

current) YES: the overload is still present. Reduce the load. NO: the overload has finished and the load is supplied by by-pass. Check that the

gauge ACCUMU on the UPSTest software is decreasing to zero. As soon as it reaches zero the inverter is switched on again.

3. Repeat the step #1. Are the values shown equal to those measured?

YES: END. Check that the load doesn’t exceed the nominal load. NO: replace the card I/S-CL

2.29 A29 – INVERTER SHORT CIRCUIT This alarm indicates that the short circuit monitor has detected a short at the output of the

inverter. The hall effect transducer(s) at the inverter input measures the inverter bridge current and send the signal to the I/S-CL on the connector M1. This signal is amplified on the test point TP2 and can be set at 4Vpeak at 100% load by rotating the potentiometer P2. As this signal exceeds two times the nominal output current, the current limitation starts to work and the alarm A25 is activated. This happens if the emergency line is not available, otherwise the load is automatically transferred to bypass. Normally the alarm A29 can be found in the alarm history, as it is automatically reset as the short circuit is removed.

2.29.1 Troubleshooting procedure 1. Are there heavy load steps exceeding two times the nominal output current?

YES: check and/or reduce the load NO: go to step #2


REV.A JSE411881 08/06/09 JUD411299 19 of 31

installed on request. The normally closed contact of the external detector is connected to the connector M18 (21-22) of the back panel card BP-DR16 (PB134).

2.30.1 Troubleshooting procedure 1. Check the external earth fault detector; is the internal alarm activated?

YES: END. There’s a earth fault, check the loads and their connections to the rectifier. NO: go to step #2

2.31 A41 – ROCB OPEN This alarm indicates that the rectifier output circuit breakers (when provided) is open. The auxiliary contacts of the circuit breaker is connected to the connector M18 of the back





2.32 PROGRAMMABLE ALARMS The alarms from A50 to A59 can be programmed during the engineering phase, in case the

technical specification requires additional signalisations. They can either be generated by mixing the standard UPS alarms or depend on the four digital inputs available (connector M1 of the front panel card FP-ACUPS).

Considering the wide number of possible combinations a troubleshooting procedure cannot be given.

4 ON-FIELD TEST PROCEDURES This chapter describes the most common operating procedures used to test the various

sections of the UPS during repairing or maintenance operations. These procedures assumes that all the power components (fuses, thyristors, cables, etc.)

are OK, no modifications have been made in the power and auxiliary circuitry and that the unit is switched off or in manual by-pass (all the control circuits are off).

4.1 INVERTER 4.1.1 General notes on the TEST mode

The TEST mode is a operating condition where the inverter doesn’t start-up automatically but waits for the commands sent by the operator through the UPSTest software. In this condition some alarms are hidden and the UPS can be tested completely. When the UPS is in manual by-pass for example, just setting the unit in TEST mode allows the operator to check the UPS operation. The TEST mode can be set by moving the DIP6 SW1 in position OFF in the card I/S-CL. The microprocessor acquires the position of the dip-switch only after it has been reset (switching off the E2001.E or by pressing the push-button SW3 in the I/S-CL).

4.1.2 EXTERNAL POWER SUPPLY It’s a special tool used to supply the microprocessor without switching on the rectifier, so that

the unit can be tested in safety.

NOTE The standard external power supply is suitable for the use with E2001.E systems having

220Vdc nominal input voltage, as its output voltage is about 320Vdc. For 110Vdc systems it is necessary to reduce the supply voltage of the external PS to 150Vdc maximum.

4.1.3 Blank test of the card I/S-CL The procedure that follows is part of the factory test procedure, related to the preliminary

checks carried out on the microprocessor board I/S-CL before proceeding with the inverter start-up. It’s useful when, after an inverter failure, the operator wants to be sure that no damage occurred to the control section.

1. Choose the inverter TEST mode, moving the DIP6 SW1 in position OFF in the card I/S-

CL. 2. Select the “manual” voltage regulation, moving the jumper J1 on the card VCB in position

2-3. This setting disable the voltage loop, and the inverter voltage regulation signal is adjusted with the potentiometer P1 of the card I/S-CL.

3. On the POWER SUPPLY board disconnect the connector CNB and connect the external power supply. The microprocessor is now supplied and after some seconds the front panel will show all the alarms present at that moment.

4. Connect the oscilloscope probe between analog ground and pin 6 of U17 and check the presence of a signal as in picture 6:


REV.A JSE411881 08/06/09 JUD411299 29 of 31

Picture 6 – Triangle waveform

NOTE For all E2001.E range the commutation frequency is set at 4kHz, so the period of the triangle

waveform must always be 250μs.

This waveform is compared with the reference sine-wave generated by the microprocessor

to create the IGBT’s PWM signals. In the following steps the sine-wave generated by the microprocessor and the IGBT’s turn-on

signals will be checked. The inverter can be turned-on only if all the software conditions are fulfilled, so it’s necessary to change the DC voltage reading (now coming from the external power supply) to enable the variable VDC_OK.

5. Change the DC voltage reading sending the command TVBAxxx, where xxx is the

desired value, and check that the command is acquired by the microprocessor and that the variable VDC_OK is activated.

6. Turn-on the IGBT modulation by sending the command INON000 or pressing F6. 7. Place the oscilloscope probe between the analog ground and pin 7 of U2 (card VCB),

rotate P1 of the card I/S-CL ( ) and check that the amplitude of the generated sine-wave increases, and then turn back P1 until the same is at zero again ( ).

8. Check that the red LED’s on the IGBT driver boards are correctly lit. 9. Verify the turn-on signal between emitter (E) and gate (G) of the IGBT’s (see picture 3). 10. Turn-off the IGBT modulation by sending the command INOF000 or pressing F7. 11. Disconnect the external power supply. After disconnecting the external power supply the microprocessor is reset and the DC

voltage setting modified before is cleared, so at the following start-up the unit will show the exact DC voltage value.

4.1.4 Inverter manual start-up This procedures assumes that all the power components in the inverter bridge have been

previously checked (see paragraph 4.1.3). The inverter output voltage is increased starting from zero to check the behaviour of the components (AC capacitors, fans, etc.) at reduced AC voltage after having identified a failure in the inverter section.

1. Choose the inverter TEST mode, moving the DIP6 SW1 in position OFF in the card I/S-

CL.


30 of 31 JUD411299 REV.A JSE411881 08/06/09

2. Select the “manual” voltage regulation, moving the jumper J1 on the card VCB in position 2-3. This setting disable the voltage loop, and the inverter voltage regulation signal is adjusted with the potentiometer P1 of the card I/S-CL.

3. Precharge the capacitors, close the input switch and supply the unit. After some seconds the front panel will show all the alarms present at that moment.

4. Turn-on the IGBT modulation by sending the command INON000 or pressing F6. 5. Verify that, after some seconds, the inverter static switch closes by checking the green

LED’s in the firing boards SCRSF-1F or 2SCR FIR. 6. Rotate P1 of the card I/S-CL ( ) and increase the inverter output voltage. Check that the

sine wave is present downstream the inverter static switch and that the shape is correct. 7. Place the oscilloscope probe between the analog ground and the test point TP2 and

check that the shape of the inverter bridge current is correct (see picture 3). 8. Rotate P1 of the card I/S-CL ( ) to set the modulation signal to zero. 9. Turn-off the IGBT modulation by sending the command INOF000 or pressing F7. 10. Open the input switch and switch off the unit.

4.1.5 Inverter automatic start-up This procedures follows the previous one and it’s used to check the correct operation of the

inverter with the voltage loop closed. 1. Choose the inverter TEST mode, moving the DIP6 SW1 in position OFF in the card I/S-

CL. 2. Select the “automatic” voltage regulation, moving the jumper J1 on the card VCB in

position 1-2. This setting enable the voltage loop, and the inverter voltage regulation signal is adjusted with the potentiometer P1 of the card VCB.

3. Precharge the capacitors, close the input switch and supply the unit. After some seconds the front panel will show all the alarms present at that moment.

4. Turn-on the IGBT modulation by sending the command INON000 or pressing F6. 5. Verify that the inverter output voltage increases up to the nominal value. If necessary

adjust it by rotating ( ) the potentiometer P1 of the card VCB. 6. Verify that, after some seconds, the inverter static switch closes by checking the green

LED’s in the firing boards SCRSF-1F or 2SCR FIR. 7. Place the oscilloscope probe between the analog ground and the test point TP2 and

check that the shape of the inverter bridge current is correct (see picture 3). 8. Turn-off the IGBT modulation by sending the command INOF000 or pressing F7. 9. Open the input switch and switch off the unit.

4.2 STATIC SWITCH 4.2.1 Check of the redundant supply

The VOLT-REF board provides a redundant supply for the static switch control logic, so that the by-pass static switch is supplied even when the microprocessor is off (POWER SUPPLY board not supplied).

1. Close the by-pass circuit breaker and check that the LED L1 in the card SCB (additional

card in the I/S-CL) is correctly lit (green). 2. Verify that, after some seconds, the by-pass static switch closes by checking the red

LED’s in the firing boards SCRSF-1F or 2SCR FIR.


REV.A JSE411881 08/06/09 JUD411299 31 of 31

4.2.2 Commutation tests The commutation tests are useful to check the correct operation of the static switch. 1. Start-up the inverter in automatic mode (see procedure at 4.1.5) and verify that the

inverter static switch closes. 2. Close the bypass breaker, wait for the status S6 – BYPASS OK is activated. 3. Measure with a multimeter the voltage difference between the by-pass input and the

inverter output and verify that it doesn’t exceed 20Vac. The inverter is now synchronised with the by-pass.

4. Move the NORMAL-BYPASS switch SW1 in by-pass position and verify that the load is transferred to the by-pass static switch. Then move it back and verify that the load is supplied again by the inverter.

5. Repeat the previous and verify that at the sixth time the load remains supplied by the by-pass and the alarm A17 – Retransfer blocked is activated.

6. Reset the blocking condition by sending the command RESE000 or entering the special menu in the front panel.

RTB.e Configuration


1. INTRODUCTION

A test and monitoring software RCN-Monitor is available for the RCN unit that allows to check all the measurements and the operating statuses of the unit via an RS232 connection, as well as to carry out settings and configuration changes on the RCN unit.

2. CONFIGURATION VIA DIP SWITCHES

Some operating parameters are configured via Dip Switches on card DR16-COMP. The setting of the Dip Switches depends on the RTB.e size.

RTB.e Configuration


3. TEST AND MONITORING SOFTWARE

RCN-Monitor software is connected from the serial port RS-232 of the PC, properly configured, to the serial port RS-232 of the RTB.e unit. For the connection a dedicated cable must be used, with the connections as indicated in the figure below. 3.1 CONNECTION CABLE

Fig. 2 – Connection cable

3.2 SOFTWARE INSTALLATION The software installation is performed like any other WINDOWS application. The software can be supplied on several floppy disks. In this case the software will

be installed starting from DISK1, or via a CD-ROM. Start the Setup program from the START menu, then follow the instructions as they

are requested by the installation software.

RTB.e Configuration


3.3 SOFTWARE DESCRIPTION The software allows to check values variables and system parameters, as well as to

perform settings. Therefore it is a necessary testing tool, whereas parameters can also be changed using the front panel.

As a rule, the software allows to display the status of the system updated in real time. Communication is therefore unidirectional from RTB.e to the PC.

When the communication is properly performed, the window named N. Bytes contains a number ranging from 1 to 250.

ISTRUZIONE OPERATIVA DI MODIFICA

Per utilizzo LEM ricarica batteria su raddrizzatori digitali in configurazione parallelo ridondante

Questa istruzione si riferisce ad una configurazione generica composta da due RTB_e e

una o due batterie. Si possono distinguere le seguenti configurazioni: 1. Due RTB_e con diodo di blocco, connessi in parallelo su un’unica barra e una

batteria collegata anch’essa in parallelo alla barra.

I due sensori di corrente di batteria devono essere collegati al connettore M7 della

N_FS3004 di ciascun RTB_e. Sul connettore M18 della N_FS3004 di ciascun RTB_e, si devono cortocircuitare con un

jumper i pin 17-18.

JRE409518 ISSUE 2

2. Due RTB_e con diodo di blocco, connessi in parallelo su un’unica barra e due batterie collegate anch’esse in parallelo alla barra e congiuntore fra i due sistemi.

Ogni batteria deve avere un sensore di corrente (Hall effect ammeter) per ciascun RTB_e. La tabella sotto riportata evidenzia la logica di collegamento dei sensori di corrente sulla N_FS3004.

BATTERIA 1 BATTERIA 2RTB_e1 M7 M13 RTB_e2 M13 M7

Sulla scheda FS1420 dovranno essere implementate le seguenti modifiche in base alla

corrente di ricarica di batteria degli RTB_e.

R122 = 10 k ¼ w R129 = in accordo alla seguente tabella
