PX, indicates the active period at any given time.

, It indicates that there is an alarm. The alarm type can be checked on the L40 screen.

When a critical alarm is triggered, the device will display the message "ALARM" in the top line in the Standby State. The various screens have to be accessed using the read button. Depending on the type of alarm, the letters C, N or B will be shown:

C: Critical alarm, due to an internal or external problem that directly affects the measurement. This will be flashing.

N: Non-critical alarm, does not affect the measurement but it does affect the operation of the meter. This will be flashing.

B: Battery-low alarm. This will be flashing.

, will have three possible states:

Off, when there are no communications. This is the default status.

Steady on,once the meter is associated.

Flashing, there are two cases:

•Continuous periodic flashing, indicates that the communications module in the meter is working correctly during the association process, but it is not yet associated with the concentrator. The flashing period lasts 2 seconds, 1 second on and 1 second off.

•Short double flashing, indicates that the meter has a connection and is associated. The shutdown time is 0.3 seconds.

R , indicates that the LED verifies the reactive measurement. Not available in three-phase energy meters

kvarh

, indicates open circuit breaker due to power control (PC) actuation. Not available in three-phase energy meters.


CIRWATT B 400

2�7 - VERIFICATION PULSES

The device has two verification LEDs, one for verifying the active energy and another for the reactive energy.

The weight of the LEDS depends on the version of the meter, and is 20,000 imp/kWh (kVArh) for an indirect and semi-indirect meter, and 4,000 imp/kWh (kVArh) for a meter with a direct connection.

The LEDs remain on when the current is lower than the meter's starting current. Once the starting current is exceeded (due to the presence of either active or reactive power consumption), the LEDs turn off and emit pulses proportional to the energy measured, as per the rate indicated on the rating label.Both LEDs have metal rings and a profile to set and help position the verification head.

2�8 - BUTTON

It relies on two keys with a short and long press system. A short press is one lasting less than 2 seconds, and a long press is one lasting more than 2 seconds. The effect of pressing each key depends on the version of the meter. One of the keys is sealed to prevent unauthorised personnel from operating the meter.

2�9 - RATING PLATE

The rating plate is located on the front of the meter and contains the specifications required in IEC 62052-11:

Manufacturer's identification mark and place of manufacture Type designation and certification markings. The number of phases and the number of conductors in the circuit to which it can be connected (e.g., three-phase 4 wires) Serial number of the meter (9 numeric characters), unique number for each meter.

2�10 - ENCLOSURE

The dimensions of the enclosure of the CIRWATT, as well as its anchor points, are in accordance with the DIN 43859 and DIN 43857 standards.

2�11 - CONNECTIONS

Laser marking on the meter enclosure. Contains a figure showing the electrical connections. When necessary, a brief installation manual is also included to facilitate the start-up process.

2�12 - AUXILIARY CONTACTS (DEPENDING ON VERSION)

The meter may have a series of auxiliary contacts with varying functions depending on the version.

2�12�1 - VERSION WITH TARIFF INDICATOR OUTPUT

The meter has a relay output (250 V and 5 A ~) indicating the activation of the tariff that has been programmed into it.

2�12�2 - VERSION WITH PULSE INPUT

The meter will have a maximum of 4 inputs for counting pulses from other devices, such as water and gas meters. The minimum pulse width time that the meter can detect is 30ms, and the maximum rate it can read is 8 pulses per second.

The inputs are self-powered at + 5V, with a maximum current of 8 mA per input. As a result, a voltage must never be applied to the inputs; rather, it must be a potential-free contact.

2�12�3 - VERSION WITH LEAKAGE CURRENT MEASUREMENT

The meter will have an input for connecting an external transformer of the Circutor WN series, which will allow reading the differential current (leakage) present in the installation.

2�12�4 - VERSION WITH OPTOCOUPLER OUTPUT

The meter has optocoupler outputs to emit pulses based on the energy recorded. The maximum voltage that can be applied is 24 V DC.


CIRWATT B 400

2�13 - REAL-TIME CLOCK

The meter has a real-time clock capable of keeping the date and time with a drift of less than 0.5 seconds/day, as specified in the UNE EN 61038 standard.

The clock maintains this accuracy whether it is powered from the mains or by its own battery.

2�14 - RESERVE POWER

The meter has a battery that allows the clock to remain operational in real time. This battery is not removable and is sized to supply power for 5 years without plugging in the meter. When the meter is plugged in, the battery consumption is zero. The use of laser-sealed batteries minimises the amount of self-discharge, which makes it possible to guarantee the battery for the 20 years of the meter's useful life.

2�15 - OPTICAL COMMUNICATIONS PORT

Every version of the device has an optical serial communications port, as per the IEC 62056-21:2003 standard. The communications port is fully compatible with the optical ports approved by the leading electricity companies.

On the surface of the cover there is a profile for properly attaching and placing the optical heads.

2�16 - PLC COMMUNICATIONS BLOCK (OPTIONAL DEPENDING ON VERSION)

The CIRWATT Type B can be equipped with an advanced communications system through the electrical distribution network (PLC). This system allows the meters to be connected to the network without the need for extra wiring, with the consequent cost reduction in the reading process and the option of telemanagement. It is based on DCSK modulation and contains a repeater system.

2�17 - RS-232/RS-485 COMMUNICATIONS BLOCK (OPTIONAL DEPENDING ON VERSION)

The meter can have RS232 or RS485 serial communications. Up to two completely independent channels may be available, with speeds of 9600 to 38400 bauds.

2�18 - ETHERNET COMMUNICATIONS BLOCK (OPTIONAL DEPENDING ON VERSION)

The CIRWATT Type B can be connected to an Ethernet network, thus providing direct access to the meter via IP.

2�19 - RESET

Locally, the device can be reset to the initial factory conditions

16

CIRWATT B 400

Instruction Manual

2�20 - CONTRACTS

In addition to the basic measurements, the device must carry out a set of calculations to ensure proper billing, which gives rise to the concept of "contract".

A contract refers to the set of parameters that structure how the measurement to be taken by the analyser is processed in order to reflect the contractual billing agreements.

2�20�1 - NUMBER AND ALLOCATION OF CONTRACTS

The meter has three contracts defined.

2�20�2 - CONTRACT PARAMETERS

A parameter is considered to be defined if it has an assigned value, and undefined if it is blank.

A parameter that is not used cannot have any value assigned from previous parameterisations, and thus it will remain undefined.

Activation dateDate from which the meter – analyser has to use the contract parameters to calculate the data nec-essary for billing.

SeasonSeason refers to each period of time into which a calendar year can be divided and during which the billing conditions associated with it do not vary. The maximum number of seasons is 4.

Two types of seasons are considered:

Winter/Summer Season. They split the year into two unique seasons bounded by the dates of the official time change. No parameterisation of any kind is needed and they are automatically adjusted each year.

Defined seasons. Each season begins on a specific date, the end of which is the start date of the next season, chronologically, regardless of the year. Each season is identified by a number starting with 1, which increases by one unit, up to a maximum of 4.

Types of daysThe days of the year are classified as:Working�Holidays�

A working day is Monday through Friday. They are all subject to the same tariff over the course of a season.

A holiday is any Saturday, Sunday and any other days specified as such. They are all subject to the same tariff over the course of a season.Public holidays other than Saturdays and Sundays will be identified by date, the format of which may contain wildcards.


CIRWATT B 400

Tariff periods� Type of dayA tariff period refers to each time block during which a specific tariff is applied. For the regulated mar-ket and ATR, these periods are defined annually by the government. There may also be other periods agreed on a contractual basis between a Customer and the Marketer. There will be a minimum of one time block and a maximum of six. Each period is identified with an increasing number, starting with 1.

Type of dayThe type of day refers to the set of tariff periods allocated to each of the 24 hours in a day.

Each type of day is identified using a number starting with 1 and increasing by one for successive types.

Working days and holidays have a type of day associated with them for each season. Every special day has a type of day associated with it.

PowerEach tariff period has an associated power, which corresponds to the value of the power contracted in each period. It forms the calculation basis for billing the excess power demanded from the mains.

If this parameter is not defined for any tariff period, this will be taken to mean that there is no power contracted by period, meaning the excess power will not be calculated. If the power is defined for at least one tariff period, the remaining periods for which it is not defined will be assumed to have a zero power defined, meaning the excess power will be calculated based on all the periods.

2�21 - CLOSE OF BILLING PERIOD

The billing period is closed when, at a given time, the following values are stored in a memory register:

Values indicated by the energy totalizers at a given time. (absolute reading)

Energy values measured from the previous close or from the start-up of the meter, if it is the first close. (incremental reading)

The measurements and calculations to be stored are as follows:

Absolute and incremental values of active energy. Absolute and incremental values of inductive and capacitive reactive energy. Calculation of the 15-minute maximum average active power. Calculation of excess power.

The closings are based on the total measurements and all the tariff periods of the active contracts.

Each closing has a date and time associated with it. A minimum parameterisable time, expressed in minutes, must elapse between two consecutive closings. By default, this time is 10 minutes.

The meter – analyser keeps a record of the last 12 closings of each of the contracts that it has, ar-ranged chronologically from most recent to oldest. The types of closings are:

Immediate closing� Closing that is done at any time by way of a manual command using a button or a communications message. The power values used are those recorded through the end of the 15-minute integration period immediately prior to when the command is given. The energy values

18

CIRWATT B 400

Instruction Manual

used are those indicated by the totalizers when the command is received. Closing using the button affects all active contracts, whilst closing using a communication message can affect one or more active contracts.

Automatic closing� These are programmable parameters that specify the date on which each contract is automatically closed. The date may contain wildcards for the month and year. This type of closing can affect one or more active contracts.

An extraordinary immediate closing is automatically done in the following cases:

Change in transformation ratio. Affects every contract.Change of power contracted by period. Affects the modified contract.Change of season or type of day. Affects the modified contract.

2�22 - MAXIMETER

The maximum refers to the highest value of average active power demanded in a 15-minute period in the time between two consecutive billing period closings.The 15-minute periods will coincide with the integration periods of the 15-minute load curve; that is, for each hour, they will start at minute 0, 15, 30 and 45, ending when the next period begins.

The maximums are associated with each of the tariff periods defined and with all the periods as a whole. Each of these values is stamped with the date, time and minute when it was recorded.

The 15-minute periods where a synchronism event, an outage or a power restoration occurs, or that have an invalid bit, change in parameters or a tamper event, will not be considered for the purposes of calculating the maximum.

2�23 - DEFINED, ACTIVE AND LATENT CONTRACTS

A contract is said to be defined when at least the seasons and the types of day are defined.

A defined contract is active when it is being used to do the calculations necessary for billing.

The three-phase TB meter allows for latent contracts. The purpose of latent contracts is to allow the parameters of the active contract to be modified at some date before it goes into effect. A contract goes from latent to active on its activation date, even if the device is not powered or when it is initial-ised after power is restored.

Once the activation date of a latent contract is reached, the analyser has to automatically close out the immediate extraordinary billing cycle of the affected contract. The parameters defined in the latent contract will be incorporated into the active contract, the parameters of the latent contract become indefinite, and the contract that had been latent until that time will be deleted.

If there is an active contract and contracts other than the existing one are defined and activated, at the time of activation, the information recorded will not be altered and the data on all the active contracts will be displayed and stored.


CIRWATT B 400

2�24 - CONTRACT MODIFICATIONS

A contract is modified when a parameter that was previously defined in a contract is defined, changed or deleted.

The modification may affect an active contract or a latent contract (if any). Although the parameters of a contract comprise a unique set, the modifications may be made partially and independently, by groups of parameters. These groups are determined by the consistency that must exist between them. If the group of power is modified, it may also be necessary to modify the group of seasons and types of days beforehand, in order to maintain consistency. The groups are:

Holidays (up to 15).Power.Automatic billing closing date.Seasons (4) and types of days (6).

The modification is done for complete groups, such that the existing parameters are deleted and re-placed by those defined in the modification.

Modifying the Powers, Periods and Types of Days groups results in the billing cycle being closed before the modification is implemented. If the two groups are modified in a single operation, only one billing close occurs. The rest of the groups are immediately implemented and do not generate any closings.

If the modification involves a reduction in billing periods, when it is activated and the billing cycle is closed, the behaviour of the meter – analyser will be as follows:

Store in memory and make available for display the records of the closings made until that time.

Store the values of the global totalizer and those whose period number is still active. From then on, the global totalizer and the totalizers for the periods whose number is maintained with the new definition will be displayed and continue to increase, whilst those that were deleted will stop being recorded and displayed.

If contract modifications are made that involve expanding the billing periods, when they are activated, the billing will be closed out and the information recorded until that moment and the values of all the totalizers will be stored. The totalizers for the new periods start from an initial value of zero, and the existing totalizers increase from their previous value.

2�24�1 - MODIFYING AN ACTIVE CONTRACT

The modification of an active contract may affect one or more groups of parameters. Its activation will be immediate. Depending on the parameters and before they can change, the billing cycle of the affected contract will be automatically closed.

2�24�2 - MODIFYING A LATENT CONTRACT

The modification of a latent contract may affect one or more groups of parameters and does not gen-erate any automatic closing.If the activation date is prior to the current date, it will behave as a modification of an active contract and will not take into account said activation date.

20

CIRWATT B 400

Instruction Manual

If a modification is made with an activation date different from the existing one and after the current date, the date of the last modification received is regarded as the new activation date.

2�24�3 - DELETION OF CONTRACTS

The deletion of a contract consists of setting all the defined parameters as undefined and no longer displaying that contract's data on the screen.

If more than one contract has been defined and is active and one of them is deleted and the rest are maintained, at the time of deletion, the billing for the contract to be deleted is closed out. From that moment on, the information pertaining to the deleted contract is erased and no information on it can be displayed, except for that pertaining to the closed billing periods that may exist. The remaining contracts and the corresponding totalizers are not modified.

2�25 - LOAD CURVE

The analyser has two load curves that comply with the specifications set out in Royal Decree 2018/1997 and its Complementary Technical Instructions. Both load curves store records with the number of pa-rameters required by law. The logging depth in both cases is 4000, and the integration period can be fully configured by the user. With a 1-hour integration period, it is possible to store more than 5 months in each load curve.

In the case of voltage failures, or if the clock is moved forward, any gaps in the load curve are filled with invalid zeros.

An incremental load curve value that does not completely correspond to the hour in which it is included is marked as invalid. For example, if it is a value that corresponds to the consumption of several hours.

If the load curve request asks for parameters that the device has not recorded, it will reply to the re-quest with the parameters that it has recorded and will send zero and invalid for those that it does not have recorded.

The resolution in both cases is 6 digits for the energy values measured in kWh or kVArh (the same as the one in the meter display). Any change in the recording period of the load curve results in the load curve being initialised.

2�26 - POWER EXCESSES

They are calculated based on the average power in the last 15 minutes and on the contracted power, as per RD164/2001.

Equation 1: Excess power�

Where:Pdj = power demanded in each of the period's 15 minutes i in which it was exceeded PciPci = power contracted in the period i in the period in question.


CIRWATT B 400

2�27 - EVENTS

The dates of every setup change, battery replacement, time change, billing period closings, etc., are recorded.

The meter is capable of storing up to 200 records . The data organisation within the file is rotational. This means that once the memory is full, the new data will overwrite the older data. This system en-sures that the meter always has up-to-date information that corresponds to the latest data obtained.

2�28 - DAYLIGHT SAVING TIME

The meter – analyser automatically changes the official time. If the device is without power at the time of the change, the change will take place when power is restored and the device is initialised.

The parameters that define this change have two different formats: one of them is generic, such that the time is updated annually automatically; the other relies on the parameters included in the specific message of the communications protocol. The formats are:

Generic format independent of the year, with month, day, time, delay or pre-set time change, as per the applicable law (last Sunday of March, and last Sunday of October)

Format that specifies year, month, day, time, delay or time change.

The parameters for changing the official time, regardless of the format in which they are programmed, are automatically updated at the beginning of the year, based on the generic format. If the message specified in the communications protocol for updating the official time change is received, the format will be modified as laid out in this message.

2�29 - SECURITY

2�29�1 - TAMPER DETECTOR

The device will generate an event and activate the alarm if the cover on the device is lifted. The alarm can only be deactivated via the communications protocol. The minimum time between two tamper events is 60 seconds.

When first initialised, the meter waits 72 hours before generating a tamper event to avoid false alarms during the installation by the authorised installer.

2�29�2 - PROTECTING THE INFORMATION STORED IN MEMORY

All means of accessing the meter's memory via communications are protected by read-write pass-words.

These passwords have over 4 billion combinations, which makes the meter highly resistant against attempts to alter the information stored on it (load curves, events, tariffs, setup).

2�30 - MEASUREMENT VALIDATION CRITERIA

The energy, maximeter and excess power records will be invalidated if a series of events occur that indicate that any of their values have been altered. In the specific case of load curve records, there is an invalidity bit (IV) that indicates that this record is not valid. Events that generate invalid measurements are classified as follows:

2�30�1 - TIME SYNCHRONISATION WITH DRIFT > T1 = 30 SECONDS

The 15-minute period in which the synchronism event has occurred will not be taken into account for the power calculation.

2�30�2 - TIME SYNCHRONISATION WITH DRIFT > 10 MINUTES

The measurement is invalidated, i.e. qualifier IV = 1.

2�30�3 - COMMUNICATIONS FAILURE BETWEEN METER AND ANALYSER

If the communication failure coincides with the change of the 15-minute time period and it lasts more than 30 seconds, the affected periods will not be taken into account for the power calculation.

If the communication failure coincides with the change of the hourly time period and it lasts more than 10 minutes, the measurement in the affected periods will be invalidated, i.e. the qualifier IV = 1.


CIRWATT B 400

2�30�4 - SUPPLY FAILURE IN AT LEAST ONE PHASE

The measurement for the period in which the failure occurred is invalidated, IV = 1.

3�9 - QUALITY OF SERVICE

3�9�1 - INTRODUCTION

Article 9, section 11 of Royal Decree 1110/2007 specifies that "Likewise, all metering equipment for customer metering points shall incorporate a record of parameters relating to the quality of the service. These records must include at least the number and duration of each of supply interruption lasting equal to or greater than 3 minutes detected by the metering equipment, as well as how long the line voltage is above or below the allowed limits".

3�9�2 -LINE VOLTAGE OUT OF RANGE

In order to correctly record any incidents involving out-of-range line voltages, five parameters must be programmed into the device. The base nominal voltage for the calculation, the separation threshold between low voltage and no voltage, the upper and lower voltage setpoints and the minimum duration of the incident. Ongoing incidents (still active) will be differentiated from closed incidents (that are over).

For each incident, the affected phase, the type of incident (over- or under-voltage), the date-time the incident starts and the date-time the incident ends will be recorded. The latter is recorded to the nearest second.

A - Rated voltage�

This is the rated value of the supply voltage (in three-phase devices, phase-phase voltage) that must be considered to determine whether the line voltage is over or under the specified limits. In devices supplied by voltage transformers, this rated voltage is the primary voltage.

26

CIRWATT B 400

Instruction Manual

B - Separation threshold between low voltage and zero voltage

This is the percent of the nominal voltage below which an out-of-range voltage incident is no longer considered, but rather a zero-voltage incident. This value is initially set at 50%.

C - Upper voltage setpoint

This is a percentage over the nominal voltage that, when exceeded, the line voltage is deemed to be excessive. Its value is set at 7%. Setting a zero value for this setpoint would effectively result in over-voltage incidents not being calculated.

D - Lower voltage setpoint

This is the percentage below the rated voltage that, when exceeded, results in an under-voltage situa-tion. Its value is set at 7%. Setting a zero value for this setpoint would effectively result in under-volt-age incidents not being calculated. The value of this setpoint must be such that once subtracted from the rated voltage, the result is a value that is higher than the threshold defined in the rated voltage.

E - Minimum incident duration

This is the minimum time that the voltage has to continuously remain outside the limit for an incident to be recorded. This time is initially set at 3 minutes. Setting a zero value for this setpoint would effec-tively result in both types of out-of-range voltage incidents not being calculated.

3�9�3 - POWER SUPPLY INTERRUPTIONS

In order to correctly record any incidents involving no voltage, 3 parameters must be programmed into the device. The base rated voltage for the calculation, the separation threshold between low voltage and no voltage, and the minimum duration of the incident.

Ongoing incidents (still active) will be differentiated from closed incidents (that are over). For each incident, the affected phase, the date-time the incident starts and the date-time the incident ends will be recorded. The latter is recorded to the nearest second.

A - Rated voltage and separation threshold between low voltage and no voltage�

These are the parameters already defined in the previous point. When the line voltage is below the rated voltage percentage indicated by the threshold, a no-voltage situation exists.

B - Minimum incident duration�

This is the minimum time that the voltage has to continuously remain below the threshold for an in-cident to be recorded. This time is initially set at 3 minutes. Setting a zero value for this time would effectively result in no-voltage incidents not being calculated.


CIRWATT B 400

4 - OPERATION OF THE METER

This section describes the performance of the device from a functional point of view; that is, it explains how to manage all the information it provides, as well as how to configure the system's various fea-tures.

4�1 - NAVIGATION AND DISPLAY MODES

The read button will be used to navigate through the different information screens. Navigating within the same level is done by using short presses. To move to a lower level, use a long press. The device will return to standby mode 60 seconds after the last button press.

4�1�1 - STANDBY MODE

The device is in this mode by default, as long as the buttons are not pressed.

The purpose of the standby screens is to display information cyclically, without having to perform any action on the meter. This type of navigation is exclusive to standby mode.

The Scroll line will alternate the information every 6 seconds. A short press of the read button will freeze the display on the totalizer reading that is being shown at that moment.

Use short clicks to move manually through all the totalizer readings. On devices set up as a simple active tariff, the standby screen will only show the active totalizer.

4�1�2 - READ MODE

Activated with a long press of the read button. Navigation within the same level will be cyclical.

This mode uses a display-tree structure arranged into three levels, which are used to access the in-formation.

The different information that can be shown on the display in Read Mode is accessed by either long or short presses of the Read button.
