4.2 Power supply The meter's power supply is a capacitive power supply for dedicated nominal voltage level from 220V–240V (-20% .. +15%). The power supply is designed to withstand an over voltage >440V for longer than 12 hours.

4.3 Readout during power outage The behaviour of the AS220 during power outage is described below

• Readout using the display After pressing the alternate button the LCD will be switched ON. The segment test will be displayed first. After pressing the alternate button again the next data of the standard data readout list will be displayed for about 10s. The LCD will be switched OFF after the following events:

- Without pressing the push button within 10s. - At reaching the end of the standard data readout list

• Readout by optical port

After pressing the alternate button the LCD will be switched ON. After the segment test will be displayed the standard data readout list of the meter can be read by the optical port. At the end of the communication the LCD will be switched OFF.

By using the exchangeable battery the readout feature is available even if the meter is not powered for longer than 4 years, depending on the number of readouts without main power.

4.4 Model variants The alpha Meter is available in several different model variants.

4.4.1 Direct connected meter (DIN version)

- 220V .. 240V, 5/60A class 1 or 2 - 220V .. 240V, 5/100A class 1 or 2

5 Measured value acquisition Page 11 of 67


5 Measured value acquisition

5.1 Measuring module The measuring module (Fig. 1) comprises a shunt for the current transformation, a voltage divider plus a highly integrated customized circuit (ASIC). The analog measured variables obtained are digitized in the ASIC and fed to a downstream digital signal processor, which uses them to compute the active or reactive powers plus the corresponding energies, and forwards energy-proportional pulses to the tariff module. By using both digital multiplication and integration, significant advantages can be achieved in terms of measuring stability and flexibility. The scanning frequency has been selected so as to ensure that the electrical energy contained in the harmonics is acquired with the specified class accuracy.

5 Measured value acquisition Page 12 of 67


5.2 Measuring principle The alpha Meter's basic hardware can be used to acquire the following measured variables: - Active demand (+P), - Active demand (-P), - Reactive demand (Q1, Q2, Q3, Q4 or +Q=Q1+Q2 and –Q=Q3+Q4) - Apparent demand (+S, -S)

5.2.1 Active demand and energy calculation The active power is obtained by multiplying the current and voltages values in accordance with Equation (1): p(t) = u(t) * i(t) (1)

5.2.2 Reactive demand and energy calculation The AS220 reactive energy measurement is implemented according the phase shift method. The reactive energy calculation is done by using a 900 phase shift between voltage and current and a following multiplication of voltage and current according eq. 1.

5.2.3 Theft resistant measurement (always run posit ive) The AS220 can be ordered with an optional theft resistant measurement that records negative energy flow as positive energy flow. This feature can be used to deter power theft or minimize the effects of improper meter wiring. The following equation shows how total active power is calculated using theft-resistant measurement. P = |+/-P| Theft-resistant measurement applies of registration of active, reactive or apparent energy. Instrumentation values, including active energy +P and –P, are also signed normally. Therefore, instrumentation can be used to investigate the meter service wiring, while the theft-resistant measurement guarantees that active energy is properly registered. Operation of the LCD energy direction indicators is modified by the theft-resistant measurement. With the theft-resistant option, the –P arrow is not used. The +P arrow signals all positive or negative active energy flow. The following figures shows how the energy direction indicators appear for negative active and reactive power when using standard measurement and theft-resistant measurement.

The display consists of the following items: Operating display The definitions for import and export of energy have been agreed in terms of the load reference arrow system (VZS). For defining the transmission direction of active and reactive power, the specifications of the load reference arrow system likewise apply. The VZS assumes that the power utility's contracting party is importing energy (+A) from the supply grid. Display of activated tariff The tariffs T1 to T4 and M1 to M2 switched on at any one time are continuously displayed. In addition, the following applies: Arrow to the right: Indicator for positive active power

Arrow to the left: Indicator for negative active power

Arrow pointing upwards: Indicator for positive reactive power

Arrow pointing downwards: Indicator for negative reactive power

The relevant symbols will flash when the meter is not programmed to measure this energy direction. The symbols for the measured variable involved have been switched off if the power is below the device's start-up threshold. Identifier and value range All digits are separated by dots (OBIS separator or decimal point). Time particulars (h, min, sec) are separated by colons, date particulars (year, month, day) by the top dots of the colons. Alarm Indicator Alarm indicator: This indicator will be displayed if any error message of the meter

occurs (F.F, F.F.1, F.F.2)



6.2 Display Modes The following principles apply for display control: Alternate button

• pressing briefly (<2s) switches to the next list value or menu option • pressing for longer (2s < t < 5s) either activates the menu options currently being

displayed or causes preceding values to be skipped • pressing the alternate button for longer (>5 s) returns you from any display mode back

into the scroll mode (rolling display)

Further principles:

• The display control and the edit function for settable values are handled by means of "single-hand operator control" in conformity with the stipulations of the VDEW -Specification, i.e. it is never necessary to operate more than one control at any one time.

• Depiction of the different values on the display in the various display modes can be parameterized.

• The default status for the display is the operating display. A change from the operating display to the "Menu [A]-key" (i.e. call or load profile).

• From standard, second or load profile call mode you jump back into the operating display through the end-of-list identifier, or automatically if no control is operated within a defined time of 30 minutes, for example, or if the alternate button has been pressed for longer than 5 s.

• The end of a list is designated in the display with the word "End" in the value range. Different operating modes for the display:

• Scroll Mode

• Display test

• Call mode "Menu alternate button" - Standard call mode ("Std-dAtA" , displaying all the list's register contents) - Second call mode ("Abl-dAtA" , displaying all the list's register contents) - Load profile call mode ("P.01" , displaying load profile values) - Log file call mode ("P.98" , displaying of log file data)



6.3 Scroll mode The operating display is the standard display function. The measured values involved are dis-played in rolling mode, with the data relevant to billing being displayed for a configurable duration (e.g. 10 s). While a measured value is actually being displayed, then it will not be updated in the scroll mode.

6.4 Display test mode

Pressing the alternate button (<5 s) causes the meter to switch over from rolling display to display test mode, in which all segments on the display are activated. The display test mode is retained from approx. 3 seconds after the alternate button is released. During the display test mode, you can press the alternate button to switch to the "A-button menu"

6.5 A-button menu The first value displayed in the menu list is the single-call menu option entitled "Std-dAtA". Every time you press the alternate button briefly again, more menu options as available will be displayed, e.g. the load profile "P.01" or the second alternate list “Abl-dAtA” . For purposes of menu option selection, the alternate button must be held down for at least 2 s. If the time limit after the last touch on the button has been reached (this can be parameterized in a range from 1 min to 2 h) or the alternate button has been kept depressed for not less than 5 s, the meter will automatically switch over to the scroll mode. While a measured value is being displayed in this mode, it will be updated in the display once a second.

6.5.1 Standard mode (Menu Option "Std-dAtA") The first value displayed in the call list is the Identifier and the content of the function error. Every time the alternate button is pressed again, further data will be displayed. In order to call up data more quickly, existing preceding values can be skipped and the value following the preceding values can be displayed. You do this by keeping the alternate button pressed down for longer than 2 s. If the time limit after the last touch on the button has been reached (this can be parameterized in a range from 1 min to 2 h) or the alternate button has been kept depressed for not less than 5 s, the meter will automatically switch over to the operating display. Extending the time limit gives you an option for testing the meter without any software tools, since the LED will flash either for +P, -P, +P/-P or Q1.. Q4, etc., depending on the measured variable being displayed (active or reactive power consumption). The final value in the call list is the end-of-list identifier, which is designated in the display's value range by the word "End" .

6.5.2 Second Standard mode (Menu Option "Abl-dAtA")

Furthermore the meter supports second standard data list (“Abl-dAtA”). The handling of this list is the same as described in chapter 4.5.1. The main difference between the 2 lists is that the “Abl-dAtA” list can be set without breaking the certification seal (see chapter 7.2).



6.5.3 Load profile mode (Menu option „P.01“)

6.5.3.1 Date selection for the day block The first value displayed in the list is the date of the most recent available day block in the load profile. Every time the alternate button is pressed briefly (<2 s) again, the display will show the preceding available day in the load profile. If the alternate button is pressed for >2 s, then for precise analysis of the day block selected the day profile will be displayed in increments of the demand integration period, provided no events have led to the demand integration period being cancelled or shortened. If the time limit after the last touch on the button has been reached (this can be parameterized in a range from 1 min to 2 h) or the alternate button has been kept depressed for not less than 5 s, the meter will automatically switch over to the operating display. The final value in the call list is the end-of-list identifier, which is designated in the display's value range by the word "End" .

6.5.3.2 Load profile values of the selected day Display of the day block selected begins by showing the oldest load profile values stored on this day (the value stored at 0.00 h is assigned to the preceding day), beginning with the lowest OBIS Identifier from left to right (time, Channel 1 value, .. Channel n value). Every time the alternate button is pressed briefly (<2 s) again, the next available measured value for the same demand integration period will be displayed. Once all the period's measured values have been displayed, they are followed by the data of the next available demand period. The last value in the call list is the end-of-list identifier, which is designated in the display's value range by the word "End" and which appears after the final load profile value of the day selected. If the alternate button is pressed for >2 s, the meter will switch back to the day block previously selected from the date list. If the time limit after the last touch on the button has been reached (this can be parameterized in a range from 1 min to 2 h) or the alternate button has been kept depressed for not less than 5s, the meter will automatically switch over to the operating display.

e) The counting of the historical data reset is counting with the highest reset counter at first (see item f). Optionally the meter can be programmed, that “*1 is always the last demand reset. If there is the next reset, *1 value goes to *2 and so on.

f) Resetting via the data interface is safeguarded by a password and/or terminal cover opening

g) During the test mode every demand reset will be performed always directly without delay.

h) A demand reset can be carried out on a daily, monthly or yearly base.

i) After power up the AS220 meter checks whether an automatic reset has to be executed during the power outage time. In that case the demand reset lockout time will not be started.

j) Optionally it is possible to configure the meter in a way, that the meter accepts only one demand reset during one month.

k) Up to 3 automatic demand resets in one month can be programmed.

8 Identifier system and data readout lists Page 21 of 67


8 Identifier system and data readout lists The alpha Meter's Identifier system can be parameterized by the user, with a total of 3 Identifier digits provided for the display and the readout over the optical and electrical interfaces. The user has the option for using an own identifier system but to follow the international standardization the OBIS Identifier system (EN 62056-61) is recommended (see appendix, chapter 20).

8.1 Standard data readout list In the attached table you will find a sample of the standard data readout list of a meter with active and reactive and demand measurement and 2 tariffs.

9 Tariff characteristics

9.1 General remarks The tariff module of the alpha meter processes the counting pulses provided by the measuring module, monitors the integrated communication modules, and operates the meter's interfaces. Depending on the meter parameterization involved, all or only some of the functions described below will be supported. Furthermore it is possible to use a separate tariff source for the energy and the demand tariffs.

9.2 Energy tariff control Overall, the meter provides 6 energy register sets for acquiring the following quantities:

• Imported and export active energy +A and -A

• Reactive energies R1 .. R4 of the 4 energy quadrants

• Combination of reactive energies, e.g. +R=R1 + R2

• Apparent energy a) Internal tariff control using internal clock See Section 9.5.4 b) External tariff control using communication inte rface

The energy and demand tariffs can be controlled by the optical or electrical interface or the communication module.

9.3 Maximum demand tariff control The block demand calculation is provided for up to 4 separate programmable maximum registers for active, reactive or apparent calculation. The total parameters provided for the block demand measurement are as follows:

• Duration of the maximum period: 15 min (configurable in the range of 1..60 min) • Up to 4 separate maximum registers each with 4 maximum tariffs M1..M4 and 4

cumulative counting mechanisms (*) • Input variables for the 4 maximum values are user-selectable, e.g. +P/Q1, +P/+Q/+S • Maximum tariffs and energy tariffs are independent of each other • Temporary maximum demand measurements • Overlapping maximum demand measurements • Each maximum value is assigned a time stamp • Saving up to 15 preceding-month values

a) Internal demand tariff control using internal cl ock See Section 9.5.4 b) External tariff control using communication inte rface

The demand and tariffs can be controlled by the optical or electrical interface too.



9.3.1 Synchronization of the demand period The integration period for the meter's maximum measurement function can be synchronized in a number of different, configurable ways: • Power failure a) Integration period is ended b) Integration period is not ended • Power recovery a) A new integration period is started, and terminated synchronously with the device time b) Depending on the duration of the interruption, either the integration period ongoing at the time of the power failure will be continued, or a new (and perhaps shortened) integration period will be begun. The end of the integration period is always specified by the IP raster. • Energy tariff change a) Energy tariff is switched over, and the integration period is affected if energy and power are not being jointly controlled b) The tariff is changed after a time-delay, and synchronized with the integration period raster specified by the device clock, if it has not occurred synchronously • Demand tariff change a) The power tariff will be changed immediately, the ongoing integration period switched over, and a new integration period started b) The tariff is changed after a time-delay, and synchronized with the integration period raster specified by the device clock, if it has not occurred synchronously • Demand Reset a) Ongoing integration period is ended, new integration period is started with the beginning of the new billing period b) The reset is accepted as preparation, but not actually executed until the next time the time filed in the device comes round (this does not apply for resets with the reset button or through the optical interface) • Setting device clock a) Setting the device clock causes the demand integration period to be terminated prematurely. The following integration period is terminated synchronously with the device time, and may be shortened if the resetting has not been synchronized so as to harmonize with the integration period raster.



9.4 Delta register values A Delta value or counting mechanism increment is the energy value, which has accumulated as a preceding value since the last demand reset. In comparison to the register reading, the Delta value represents the energy of the variable measured between two defined points in time. In the AS220 meter, Delta values and register readings can be displayed in parallel. When Delta values are displayed and read out, they are identified with their own Identifier, distinguishable from the meter readings.

9.5 Real time clock 9.5.1 General characteristics of the real time cloc k

The AS220 RTC (real-time clock) possesses the following characteristics:

• The time basis is derived from the internal oscillator with an accuracy of <5ppm (<+/- 0.5s per day).

• The energy for the running reserve is supplied by an internal battery (>5 years backup time).

• After the running reserve has been exhausted, the device clock will start after power up with the time and date information of the last power outage. An associated error identifier can be read out.

• Time and date can be set by using the optical or electrical interface.

• The real-time clock supplies the time stamp for all events inside the meter, such as time stamp for maximum measurement, time stamp for voltage interruptions, etc.

• It has been specified that two-digit year figures from 90 up to and including 99 are assigned to the twentieth century. Two-digit year figures in the range from 0 to 89 will be linked to the twenty-first century.

• If the real-time clock stops running the meter can be set to a predefined tariff.

9.5.2 Correction of the RTC There are several options for correcting the RTC clock of the meter. "Correcting" in this context means "synchronization" of the device clock, i.e. the clock's deviation lies in the range of 1% of the demand period. In this case, a running integration period will not be restarted. If the deviation is greater than this specified value, we speak of "setting" , i.e. the clock is synchronized and the integration period restarted.



9.5.3 Battery backup

9.5.3.1 Internal battery To keep the RTC of the meter running the AS220 owns an onboard soldered battery, which is located on the PCB under the main cover of the meter. The features of the battery are:

• Nominal voltage: 3,6V • Nominal capacity: 0,22Ah • Life time: >10 years (nominal conditions) • Shelf time for RTC: >4-5 years (nominal conditions)

9.5.3.2 External battery As an further option the meter can be equipped with an external, replaceable battery which is located under the terminal cover of the meter (see fig. 8). With this external battery the RTC running and readout without power feature works as listed below: - internal supercap: keeps the RTC running and supports the readout of the meter without

Main power in the first 12h of power outage

- internal battery: keeps the RTC running and supports the readout of the meter without Main power after the supercap is empty (4-5 years)

- external battery: the additional external battery keeps the RTC running and supports the readout of the meter without main power after the supercap is empty (>7 years):

Fig. 7 Location of the exchangeable battery



9.5.4 Internal tariff table The internal tariff table can be used to control tariff switchover functions at specified times of the day. The switching times are here defined by the switching table. For up to 4 different day types (e.g. workday, Saturday, Sunday, Holiday), different switching tables can be specified. In addition, up to 4 seasons can be defined, with an option for having different switching tables in each of the seasons concerned. The maximum possible number of switching tables is thus: 4 day types * 4 seasons =16 switching tables Example of a switching table:

- Switching table applies for Season 1 (1 Jan - 31 March) - Within Season 1, the switching table applies on workdays only - Switching times:

06:00 T1,M1 operative 22:00 T2,M2 operative, etc.

For the "Holiday" day type, the meter incorporates a Holiday table, where a year's fixed and movable Holidays can be entered. The parameters for the integrated clock can be read off at the meter's display using a switching number. Besides tariff control, the integrated lock timer is also used to form the maximum integration period and the time stamps for maximum demand, load profile and logbook (Fig. 9).

9.5.5 Future / deferred tariff table The meter can optionally be programmed with a second internal tariff table, which has the identical structure than tariff table described in chapter 9.7.4. The future tariff table can be programmed with a fixed date (at 00:00), where the tariff table will be activated automatically. The tariff table 1 will be overwritten and the internal tariff control of the meter will only be done by this second tariff table. This feature is very useful for future tariff changes.

10 Load profile of billing data Page 28 of 67


10 Load profile of billing data By using the internal load profile storage the actual demand or energy over a selectable period (1...60min) can be stored. At the end of the storage capacity the oldest value of the load profile will be overwritten by the actual one. With the load profile memory approved by the PTB, load profile memory contents are interrogated and output in conformity with the VDEW requirements. The contents of the output data records are formatted in terms of their data structure in con-formity with EN 62056-61 (OBIS). The load profile memory possesses the following characteristics:

• Number of channels: 1-8 • Measuring quantities: +P, -P, Q1, Q2, Q3, Q4, +Q, -Q, +S, -S • Memory depth: small load profile storage

- 30 days for 1 channel (15min period) large load profile

- 260 days for 1 channel (15 min period) Remark: the size of the load profile storage decreases with the number of channels The following types of measuring values can be stor ed in the load profile storage:

• Demand values per period • Energy values per period • Energy Register every period

10.1.1 Features of the load profile storage • Load profiles are read out using the formatted "R5" command, which causes a load profile

formatted with OBIS to be output. The reply generated by the meter here is given as a self-sufficient telegram.

• Recorded profiles can be deleted using the "W5 " command defined to supplement DIN EN 62056-21

Please note: erasing the load profile memory will automatically erase the log file. • If the meter does not support the OBIS Identifier requested, it will return this as an echo

response. The part contained in the reply telegram between the two brackets (which function as separators) is omitted completely.

• If in conjunction with the load profile readout there is no entry in the inquiry for the OBIS Identifier of a measured value, the meter will respond with all available measured values in its profile.

• If the meter does not incorporate an internal device clock, then the following data will be output instead of the time stamp:

- for the date of the string: "999999" (OBIS Format: D6) - for the time of the string: "999999" (OBIS Format: Z6) - for the time stamp of the string "999999999999" • The telegram formed as the reply corresponds to the form specified in OBIS. It contains in

the "Address" field of the first data record the OBIS Identifier of the first load profile excerpt of the reply. This is followed, in accordance with the definition specified in OBIS, by a

10 Load profile of billing data Page 29 of 67


header-specific number of bracketed additional values, to which are appended the likewise bracketed elements of the load profile excerpt.

• If in the interval specified there is more than one section of the load profile, then a new header will be inserted for each such section. The formation of new profile headers during load profile transfer is explained with the events and status changes coded in the first 8 bits (Bits 7 to 0) of the profile status word. The time stamp in the header is assigned not to the transactions, but to the formation of the first profile value.

• The overall length of the telegram answered will depend on the size of the interval desired. The time stamps in the reply telegram are of the "ZSTs13" type. Output of the telegram's data always begins with the oldest interrogated value.

• If the order includes a request for a time range for which there are no entries, the meter will respond with "P.01 (ERROR)”.

• If the order requests a Identifier which the meter does not support, the meter will merely supply the values for the Identifier it does know.

12 Inputs / Outputs Page 32 of 67


12.3 Overload Control With the AS220 it is possible to use a control output for load control opportunities. After exceeding a predefined threshold an output contact can be closed (opened). The number of overload exceeds can be counted and/or stored in a log file. The user can define 2 different thresholds for one control output.

a) The format of the selectable overload threshold and the demand are the same. b) At the begin of the period the output contact will be opened (closed) c) The output contact will be closed (opened) under the following conditions:

P15 > Pthreshold

with P15 : actual 15min demand ( P15 = P * t / tp) Pthreshold : overload threshold tp : demand period (15min) t: actual time of the 15min demand period

d) example nominal voltage: 3x230/400V current: 6A Overload threshold: 0.5kW

t = (Pthreshold / P) * 15min = 0.5/(3*230*6)*15min = 01:49 (mm:ss)

13 Security functions Page 33 of 67


13 Security functions

13.1 Error messages The AS220 meter regularly executes self-test routines running in the background. These are used to test all important parts for proper functioning. If there is a malfunction or an operator error, the error messages and/or diagnostic alarms on the display will output a detailed error Identifier, which can be evaluated via the optical or electrical interfaces. It can contain one or more error messages.

There is also an option for displaying the error message in conformity with the OBIS Identifier Number system and the VDEW Specification (Identifier "F.F"). Note that the VDEW Specification subdivides errors into 4 groups. The significance of the individual bits in each group can be selected on a manufacturer-specific base. In the alpha Meter, the following specifications for fatal errors apply, beginning from the left: If any error condition (F.F, F.F.1, F.F.2) will occur, an alarm indicator on the LCD will be activated (see chapter 6).

13.1.1 Certification relevant alarms

Error identification with ODIS Identifier F.F If an error of this kind occurs, the meter's certification will be cancelled, and the display will be frozen ("F.F * * * * * * * * "). The error identifier can also be read out through the electrical or optical interface.

13.2 Terminal cover removal detection The terminal cover opening will be detected if the event stays longer than a programmable time of 0-120s. The following actions are done:

• Error message on the LCD (F.F.1 00010000)

• Display of error symbol

• Detection of the last 10 with start and end time&date. This event list can be readout by the standard data readout list.

• After the detection of 10 events the latest event will be overwritten

The error message will be reset by use of the “Reset of event logs” or “register reset”.

13.3 Main cover removal detection The main cover opening will be detected if the event stays longer than a programmable time of 0-120s. The following actions are done:



• Detection of the last 10 events with start and end time&date. This event list can be readout by the standard data readout list.



13.4 Magnetic tamper detection The magnetic tamper detection will be active if the event stays longer than a programmable time of 0-120s. The following actions are done:






13.5 Reverse run detection The reverse run detection will be active if the event stays longer than a programmable time of 0-120s. The following actions are done:








13.6 Basic log file 13.6.1 Characteristic of the log file By using the log file of the meter the following events can be recorded with the current time & date stamp:

• Power outage • Change of time & date • Malfunction of the meter • Demand reset • Reset of load profile/logfile • Energy or demand tariff change • Loss of time & date • Change of meter configuration • Detection of terminal &main cover removal • Magnetic tamper detection • Reverse run detection • With every power outage the total active energy register T0 can be stored in

the log file

13.6.2 Certified log file The log file of the meter can be used as a „certified log file“. It is not possible to delete the log file without breaking the certification seal. Therefore it is allowed to change the meter LED and pulse output constants under the following conditions:

• The indication of the pulse constant have to be displayed on the LCD • The change of the pulse constant is done by formatted command • Every change of the pulse constants will be registered in the log file with

Time & date stamp: identifier, previous constant, new constant • The log file can only be erased by breaking the certification seal • The load profile storage has the same size as the load profile storage

13.6.3 Log file format The meter's operating logbook entries can be read out in accordance with the procedure selected for outputting the load profile: • The operating log file is treated like a load profile. The Identifier "P.98" designates the

operating logbook of the VDEW Specification meter • The operating log file is read out using the "R5" formatted commands, which are specified

as follows to supplement DIN EN 62056-21: The "R5" command causes a load profile formatted with OBIS to be output. The answer generated by the meter in response is given as a self-sufficient telegram.

• Erasure of the operating log file is performed using the "W5" command defined to supple-ment DIN EN 62056-21.

Erasing the log file automatically causes the load profile memory to be erased • If a time range is requested in the order, but there are no entries for it, the meter will

respond with "P.98 (ERROR)”. • The status word describes the event or the status change which has led to the event in the

logbook. In the status bit, however, it is perfectly possible for more than one status bit to be set to "1". Which event entails which element information is defined below:



13.6.4 Readout modes of the log file by using R5 / R6 - commands The orders listed below can be sent to the meter:

13.7 Second log file – storing meter configuratio ns A second log file can be activated in the meter. In that case it is possible to store the last 30 events of a meter configuration change with time and date stamp. This feature can be used to detect unknown manipulation of the meter programming. The following data can be stored:

• Change of meter configuration • Reset of register (billing) data • Reset of billing load profile • Reset of power quality monitoring profile



13.8 Standard register data list In addition to the log file, the following events, errors or operating malfunctions can be outputted in the AS220 in the normal readout mode, using the appropriate OBIS Identifier. All the parameters can be assigned to one of the 2 data readout list (see chapter 7.1 and 7.2).

• Number of total duration of all power failures • Number of power failures • Beginning and end of the last interruption in power supply • Number of communication processes • Number of maximum resets • Date and time of the last demand reset • Date of last parameterization • Error messages • Status information (power outage, etc., see chapter 9.7)

Additionally the following last 10 events can be displayed in the register data list:

• Counter + Start and end of power outage with time and date stamp (OBIS ID: 96.77. - counter) (OBIS ID: 96.77.xx - last 10 time & date stamps) • Counter + Start and end of reverse energy flow with time and date stamp (OBIS ID: 96.72. - counter) (OBIS ID: 96.72.xx - last 10 time & date stamps) • Counter + Start and end of main cover removal with time and date stamp (OBIS ID: 96.70 - counter) (OBIS ID: 96.70.xx - last 10 time & date stamps) • Counter + Start and end of main cover removal with time and date stamp (OBIS ID: 96.71 - counter) (OBIS ID: 96.71.xx - last 10 time & date stamps) • Counter + Start and end of magnetic field detection with time and date stamp (OBIS ID: 96.78 - counter) (OBIS ID: 96.78.xx - last 10 time & date stamps)

13.9 Data integrity In designing the AS220, special attention has been paid to measuring stability and the integrity of the billing data acquired. The extensive integrity concept is based on several different components. Crucial parts of the hardware are in redundant design. Billing data are, for example, stored in an EEPROM and also held in a buffered RAM. This means the integrity of these data can be cross-checked. In the software, checksums are regularly formed for the crucial billing and parameterization data. Any malfunction is immediately indicated on the display with an informative error message. There is also an option for closing a forwarding contact, if a malfunction occurs. Data are saved automatically in the EEPROM:

• during a power failure • after a tariff or maximum switchover • or at the latest every 24 h



13.10 Security protection against reprogramming The alpha Meter possesses different security levels.

• Password for all parameter changes

• Selectable IEC address for electrical and optical communication (only by sending the IEC address a successful communication can be achieved)

• Hardware protection by terminal cover removal

• Hardware protection b internal Jumper (under certification seal)

The security protection can be programmed as described in table 2. For optical and electrical interface the following parameters can be secured by different passwords, terminal cover opening separately.

17 Calibration and test Page 47 of 67


17 Calibration and test

17.1 Calibration The alpha meter AS220 has been adjusted in the factory, with the calibration constants matched to the software concerned. Subsequent calibration by the customer is not required.

17.2 Accuracy test using a test bench For testing the AS220 meter with a test bench the user should be aware that the AS220 has no voltage and current bridges.

17.3 Manufacturer specific test mode By sending a formatted command through the optical interface, the meter can be put into a special test mode, for reducing the test duration’s involved. In this test mode, the following parameters can be selected:

• Automatic increase in the decimal places for energy values to 3, 4 • Increase in the LED's flashing frequency (Imp/kWh)

• Increase the flashing frequency (Imp/kWh) of the pulse outputs

• Assignment of measured variables (+P, -P, Q1 .. Q4) to the LED

Remark: this feature is necessary for testing the reactive energy measurement • Selection of desired energy (T1-T4) or demand tariff (M1-M4)

If you switch over to call mode during the test mode, the Identifier selected and the corresponding measured value will remain on the display until a new call is made or the power supply is interrupted. The measured-value display is continually updated. The test mode can be quit via the following events:

• Formatted command

• 24 hours after activation

• pressing the [A]-button >5s

17 Calibration and test Page 48 of 67


17.4 Simplified test mode For a simple function test routine not requiring any special software tools, you can use the following function: if you select a power or energy value in the display, the LED will flash either in accordance with (+P/-P) or in accordance with the reactive power (Q1 .. Q4). This makes it relatively easy to detect which value is being measured. The maximum retention time of the display value can be set by the customer. If you press the parameterization key before this test, then the display values selected will be retained in the display.

17.5 Simple creep and anti-creep test The shortened creep and anti-creep test can be shown on the LC display or the shared LED.

• Display Arrow in display "ON": meter starts measuring

Arrow in display "OFF": no energy is being measured. This applies for all 4 possible energy types (+P, -P, +Q, -Q)

• LED

"Standstill" is signaled by a steady-light at the LED. In any other case the LED indicates energy-proportional pulses.

17.6 Checksum display By configuration it is possible to display a checksum over all setting- and parametrization classes of the meter. With that 8 digit number is very easy for the customer to proof, if the meters have an identical parameterization.

19 Installation and start-up Page 50 of 67


19 Installation and start-up

19.1 Installation and general function control The meter is mechanically secured in place by first suspending it in the upper eye, and screwing it into position through the two bottom mounting points to the left and right of the terminal block. The suspension eye enables the meter to be installed in either an open or concealed configuration as desired. Using these 3 mounting points, the meter is installed on a meter panel. If the meter has started up, this will be indicated directly by an arrow in the display, and by the energy pulse LED, which will flash in accordance with the preset pulse constant (Fig. 10).

19.2 Installation check using the meter display After the meter has been properly connected, its function can be tested as follows: Scroll mode As long as the alternate button is not pressed, the scroll mode will

appear. Depending on the version involved, this may consist of one value or of several values, shown in a rolling display mode.

Display check When the alternate button is pressed, the first thing to appear is the

display check. All segments of the display must be present. Pressing the alternate

button will switch the display to its next value. Error message If the display check is followed by an error message, it can be

interpreted as explained in Section 9. Fast run-through If the alternate button is repeatedly pressed at intervals of 2s < t <5s ,

all the main values provided will appear. Creep check If the meter starts measuring, the energy pulse diode will blink

according the measured energy. The relevant arrows (+P, -P, +Q, -Q) on the display are switched ON after 2-3s. Anti creep check If the meter is in idling mode, the energy pulse diode will be

continuously lit up. The relevant arrows (+P, -P, +Q, -Q) on the display are also switched off.



19.3 Installation recommendations During the installation the following issues should be considered

WARNING

Installation must be always carried out by appropriately trained and qualified personnel in accordance with normal metering custom and practice.

The installer is responsible for the choice of connecting cables that must be appropriate for the voltage and current rating of the meter and for ensuring that the supply is properly fused. It is recommended that meters are protected by fuses equal to the meter rating. i.e. fuse for a meter.

Isolate all circuits before carrying out the installation.

Refer to the nameplate to ensure that the correct meter is being installed.

Refer to the connection diagram inside the terminal cover. Failure to comply with these instructions may result in damage and/or electric shock

23 OBIS identifiers of AS220 Page 57 of 67


23 OBIS identifiers of AS220 In the following chapter all the OBIS-identifiers are listed, that are supported by the meter AS220. All data can be readout on the LCD or optical/electrical interface. The amount of OBIS identifiers can be roughly subdivided into two large groups:

1. Identifiers for measuring values; these are starting with a number between 1 and 89. 2. Identifiers for general purpose objects ; these are starting either with a “0”, a “C” or a

“96”

23.1 Identifiers for measuring values As mentioned above, these are starting with a number between 1 and 89 (after the optional “medium/channel”-sequence); these are called “value group C” in EN 62056-61. The number represents the type of measuring, e.g. 1 = “active power +” or 31 = current L1”.

The second number (“value group D”) stands for the measuring type, e.g. x.5 = “last average” or 8 = “time integral 1”.

The third number represents the actual tariff; if 0 ⇒ no rate.

Below you will find a list of all possible combinations, delivered by the meter. In order to shorten the list, the tariff, if delivered, is represented by the placeholder “t”, this can be a cipher 0..4.
