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 positive)
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.

Product manual 1.9
AS220
6 Display Control
Page 14 of 67
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 Display Control
Page 15 of 67
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 Display Control
Page 16 of 67
6.3 Scroll mode
The operating display is the standard display function. The measured values involved are displayed 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).

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.

b) The demand reset disable time can be configured to be cancelled by a power failure.
c) If during an activated demand reset disable another reset is executed through the optical or
electrical data interface, then on the display all segments show the letter “E”.
d) The demand reset counting mechanism can run either from 0..99 or from 1..12, to correspond to the months of a year. The number of the reset counting mechanism simultaneously
serves as an auxiliary Identifier for the preceding values.

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.

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 interface
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 clock
See Section 9.5.4
b) External tariff control using communication interface
The demand and tariffs can be controlled by the optical or electrical interface too.

Page 24 of 67
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 clock
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.

9.5.3.2 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):

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 conformity with EN 62056-61 (OBIS).
The load profile memory possesses the following characteristics:
•
•
•
Number of channels:
Measuring quantities:
Memory depth:

- 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 stored 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
Product manual 1.9

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.

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.

•
•
file of the meter the following events can be recorded with the current time &
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 supplement 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:

13.9 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

16.2 AM700 module – RS485 + DLMS protocol support
The AM700 module offers the following features:
•
•
RS485 interface for connection up to 32 meters to a bus
EN62056-21 to DLMS protocol converter
Electrical characteristics:
Protocol:
Baud rate:
Terminating resistor:
terminals brought out: RT+ (Data+), RT- (Data-)
as per EN 62056-21
max. 9600 baud
The bus has to be terminated with 100 ohm.
By using the RS485 interface up to 32 meters can be connected with a line length of 1000m.
The used protocol corresponds to EN 62056-21. In that case the IEC meter address should be
used for reading the meters. In the following figure describes the way to use the RS485
interface in combination with different meter types.

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

17.4 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.

18.1 Reading and configuration tool alphaset
The alpha Meter can be read out, set and parameterized via the optical or electrical interface, in
accordance with the EN 62056-21 protocol.
For this purpose, you need the alphaSET readout and setting tool, which can be used to alter
and read out the meter's register contents, load profile and logfile data and all setting
parameters. The program is a 32-Bit application and runs under Windows 95/98, Windows
2000, Windows XP and Windows NT.
AlphaSET supports the following functionality:
Readout parameters
• standard data list
• Service list (second data readout list)
• Log file
• Load profile of billing data
• Profile of instrumentation parameters
• Complete meter configuration
Change of meter parameters
• Identification and passwords
• Switch time clock parameters
• Demand reset parameters

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
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.
