The EIB Delta-Meters are suitable for installation in distribution boards
or small enclosures, for wall mounting or panel mounting.They can be
snapped onto 35 mm mounting rails, according to DIN EN 50 022.
Connection: The electrical connection is carried out via screw terminals.
The terminal markings and insulation strip lengths are embossed in the
terminal area of the meter.(Wiring diagrams can be found in section 5.3).
The connecting screws should be tightened using the following torque:
Main terminal:
– Direct connected meter (M5 screw) 2.0 Nm
– Transformer rated meter (M4 screw) 1.2 Nm
When connecting aluminium conductors, the contact surfaces of the
conductors should be cleaned, brushed and greased.The connecting
terminals should be re-tightened after approx. 6 to 8 weeks.
Maintenance procedures can be simplified by using external terminal blocks
when connecting a transformer.
Fuse protection: The voltage circuit should be protected by a series-
connected,
miniature circuit-breaker, in order to prevent the meter from being
damaged in the event of a short circuit or overload.
– Direct connected meter max. 65 A (63 A)
– Transformer rated meter max. 6 A
Seal: To protect the EIB Delta-Meter from being tampered with after
installation and programming, it is possible to seal the device at four points.

Various measurement methods are used in the EIB Delta-Meters depending
on the type of meter.The following equations are vector equations.
Measurement method with one measuring element
This method only produces the correct result if the phase load is symmetrical.
P = 3 · IL3 · UL3
This method is not suitable for carrying out
accurate measurements in polyphase
voltage networks as 100% symmetrical
loading seldom occurs.
Measurement method with two measuring elements
This method is used in polyphase voltage networks without a neutral
conductor (three-wire network) with symmetrical or asymmetrical loading.
P=U
L1 · IL1 + UL2 · IL2 + UL3 · IL3
ΣI=I
L1 + IL2 + IL3 = 0
P = UL1 · IL1 - UL2 (IL1+ IL3) + UL3 · IL3
P = IL1(UL1 - L2) + IL3(UL3 - L2)
This method (with 2 measuring elements) is not suitable for carrying out
accurate measurements in networks with inductive or capacitive loads with a
low cos ϕ. In this case, the method that uses 3 measuring elements should
be selected.
Measurement method with three measuring elements
This method is used in polyphase voltage networks with a neutral conductor
(four-wire network).It can however also be used in networks without a
neutral conductor, provided that an artificial neutral point is created.
P = UL1 · IL1 + UL2 · IL2 + UL3 · IL3
This method is very accurate, even in the
case of asymmetrical loads and low cos ϕ.

Active and reactive power: Capacitive or inductive loads cause a phase
angle shift between the phase current and phase voltage.
The maximum permitted phase angle shift is often contractually defined by
the power supply companies. So that the specified values are not exceeded,
power factor correction systems are often installed and the consumption is
monitored using reactive energy meters or combination meters.
So that energy consumption can be measured in installations with current and
voltage levels beyond the nominal measuring range of the EIB Delta-Meter, it is
necessary to use current and/or voltage transformers.It is important that the
secondary current and voltage of the measurement transformers, lie within the
permitted measuring ranges of the transformer rated meter. In order to
guarantee the required level of accuracy, the selected transformers should
have a higher accuracy class than the meter.The current transformers must be
connected with the correct polarity (K1 ⇒ L1, k1 ⇒ l1).
Note: The secondary measuring circuits of the transformers must be laid
separately to the main power cables to eliminate induced current errors.
The terminal block indicated above is not absolutely necessary for the
installation but simplifies servicing procedures.

Power consumption of the secondary measuring circuits: If current
transformers are to be connected to an EIB Delta-Meter, it is necessary to
consider the power consumption of the entire secondary measuring circuits
when selecting the current transformers, so that accurate measured values
are achieved.The nominal power of the current transformer (Ssec) must be
selected according to the power loss of the connected meter and the power
loss of the secondary measuring circuits.
The following applies:
Ssec ≥Scable + Smeter S = Apparent power (VA)
The table of recommended values below represents the power consumption
of the cable (Scable) as a function of the cable length and cross section.

Energy summation: If the energy of several loads is to be measured using
a single electricity meter connected to more than one current transformer per
phase, the individual lines that are assigned to the current transformer must
be operated in parallel.All current transformers used must have the same
transformer ratio.The total of all the currents may not exceed 6 A.
In the example shown (three-wire network), the meter measures the total
energy consumption of cable 1 and cable 2.The type of load (asymmetrical
or symmetrical) is not significant in this case.
The same application is possible in a four-wire network. Current transformers
must then be operated in L1, L2, L3.The current transformers must be
connected with the correct polarity (K1
⇒ L1, k1 ⇒ l1).

The energy consumption can be read out from the LCD display of the EIB
Delta-Meter and can also be recorded and processed remotely using the EIB
communication interface.
In the case of direct connected EIB Delta-Meters, the energy in the LCD
display is identical to the energy that has been consumed. If current and/or
voltage transformers have been used, the displayed consumption value must
be multiplied by the transformer ratio (CT x VT) in order to determine the
actual, primary energy consumption.
All transformer rated meters display secondary measured values.
The light-emitting diodes next to the meter readout and the LCD display
symbols [A] and [R], flash at a rate [Zk] of:
Direct connected meter 1000 Imp/kWh (kvarh)

In addition to the energy consumption values, the multifunctional LCD
display shows the user the parameters outlined below.
➀Active power indicator: The symbol flashes dependent on the
instantaneous active power consumption.
Direct connected meter: 1000 Imp/kWh
Transformer rated meter: 5000 Imp/kWh
➁Voltage indicators: The symbols L1, L2 and L3 are constantly lit if the
corresponding phase voltage has been connected.
Note: In the case of three-wire, polyphase meters, only voltage indicators
L1 and L3 normally light up.
➂Status indicator: The text indicates whether the device is ‘OK’or there is
an ‘Error’, i.e., device or installation errors present.
➃Operational indicator: The ‘Hand’symbol lights up if a push button action
is expected.
➄Reactive power indicator: The symbol flashes dependent on the
instantaneous reactive power consumption.
Direct connected meter: 1000 Imp/kvarh
Transformer rated meter: 5000 Imp/kvarh
➅ Tariff indicators: The symbols T1, T2, T3 and T4 indicate the active tariff
and the tariff that is currently on the LCD display.
No symbol is lit = The sum of all tariffs is displayed.
Only TX flashes = Tariff X is active and is displayed.
TX flashes and TY is constantly lit = Tariff X is active, tariffY is
displayed.
➆Mode indicator: The arrow symbol changes with the display mode.
No arrow = ‘Normal mode’
Arrow lights up = ‘Alternative mode’
Arrow flashes = ‘Instrument mode’
➇Function indicator:: The arrow symbols rotate at a constant speed, if the
current lies in at least one phase above the starting current.
Note: The arrows rotate even if the direction of current flow is incorrect.
➈Unit of measurement: Indicates the unit of the measured value in the
LCD display.

Displayed energy: The energy is displayed with a resolution of 0.1 kWh
(kvarh).In ‘Alternative mode’, the consumption value is displayed with an
additional decimal place after the point, e.g., 0.01 kWh (kvarh).
In the case of combination meters, the displayed consumption value alter-
nates approx. every 6 seconds between active and reactive power.The type
of value can be seen by the unit of measurement, i.e., kWh or kvarh.
In the case of tariff meters, the displayed consumption value also alternates
approx. every 6 seconds between each of the four tariffs and the sum of the
tariffs. Using the tariff indicators, it can be determined which tariff value is
currently being shown.
In the case of transformer rated meters, all displayed consumption values
and electrical measured variables are secondary measured values.
Note: The measurement of energy consumption takes place in all display
and programming modes. In the event of voltage failure or disconnection of
the device, the current measured consumption value is maintained, in spite
of the LCD display being inactive.
The EIB Delta-Meters have a light sensor (see ‘General description’).This
has the same function as the ‘SCROLL’ button if a torch for example is shone
on the sensor.This enables the meter readings to be queried both in the
case of programmed devices and installed or sealed devices.
It is not possible to modify any settings with the light sensor.
The various read-out options of the EIB Delta-Meter are activated using a
menu-driven software.This menu is operated via two buttons:
‘SET’ button: It is used to activate the display menu [Menu mode] and the
sub-menus [3 Error] and [4 Instr].
‘SCROLL’ button: It has two different functions depending on the length of
the push button action:
●When the ‘SCROLL’ button is pressed briefly, you can jump between the
individual items in the respective menu.
●A long push button action (> 3s) switches from ‘Normal mode’to
‘Alternative mode’and from ‘Alternative mode’to ‘Instrument mode’. In all
other modes, a long push button action acts as a “Escape” function.
(The software jumps back one menu level).
Only one button may be pressed at a time.
The commands are only carried out once the button has been released.
If no buttons are pressed for two minutes during the programming, the
EIB Delta-Meter cancels the action and jumps back one menu level.This is
repeated until the meter is in ‘Normal mode’.

The installation self-test checks the connection and wiring of EIB Delta-
Meters and can detect the following installation errors:
●current or voltage connections that are missing or have reverse polarity
●current, voltage or frequency values that are outside the specified
tolerance
●internal errors
The installation self-test is carried out automatically approx.every 8 seconds.
If device or installation errors occur, they are reported on the LCD display
with the ‘Error’ signal.
To simplify the fault removal process, the various types of errors are also
displayed as installation error codes.These error codes can either be read out
in‘Alternative mode’or Menu mode [3 Error].A detailed description of the
error codes and notes on remedying the fault can be found in section 5.1.
Note: So that the EIB Delta-Meters can successfully carry out the installation
self-test, the meter must be connected with all phases and there must
be a load current of at least 100 mA per phase in the secondary
circuit.

The measured variables are measured again approx. every 5 seconds and
can either be read out in ‘Instrument mode’ or in Menu mode [4 InStr].
In the case of transformer rated meters all measured variables are
secondary values.
The measuring accuracy of all the values corresponds to the requirements of
the norm IEC 1036 within the supply voltage tolerance of ± 20 % and the
current range of 0.05 Ib(nominal current) to Imax (limit current).

4 EIB application
software
4.1 General Depending on the type of meter, the following three application programs are
available for the EIB Delta-Meter electricity meters:
●Active energy meter/1.1
●Tariff meter/1.1
●Combination meter/1.1
Active energy meter/1.1: The application software “Active energy meter/1.1”
can be used for all EIB Delta-Meter electricity meters except for the tariff and
combination meters.This applies irrespective of other meter properties
(e.g.whether the meter is a direct connected or transformer rated meter, is
used for two-, three- or four-wire systems or which operating voltage the
meter is connected to).The application software enables the transfer of the
meter reading with various transmission procedures as well as the transfer of
the instantaneous power and the status of the meter via the ABB i-bus®EIB.
Tariff meter/1.1: The application software “Tariff meter/1.1” is used with all
tariff meters that have EIB capability, i.e., the following meter types:
DZ 4000 WT E
DZ 4010 WT E
In addition to transferring the meter readings (4 tariffs and sum), the meter
status and instantaneous power, the tariffs can be controlled via the
ABB i-bus®EIB with this application software.
Combination meter/1.1: The following combination meters are programmed
using the application software “Combination meter/1.1”:
DZ 4000 K E
DZ 4010 KE
This application software enables the meter reading and instantaneous
power to be read out via the ABB i-bus®EIB.This applies to the proportion of
both active and reactive power consumption.
Warning: This device cannot be programmed correctly without Service
Release B or higher of the EIB Tool Software ETS2 V1.1.
It is therefore necessary to install Service Release B or higher on
the commissioning PC before programming the application
software. If this is not carried out, the device cannot function and
can no longer be programmed.Service Release B or higher is
available on the ABB CD-ROM and on the Internet page
www.eiba.com.

The three application programs “Active energy meter/1.1”, “Tariff meter/1.1”
and “Combination meter/1.1” have various communication objects according
to the functionality of the EIB Delta-Meter (see graphic).
Many of the communication objects are dynamic and only visible if the
corresponding parameters have been activated in the application software.
These communication objects are inactive or disabled at the start of the
project design process.Only one group address can be assigned to each
communication object.
4.2 Communication objects

EIB Delta-Meter
Electricity Meters

ABB i-bus®EIB
Meter reading [EIS 11; 32 bit counter]: The measured energy consumption
values or meter readings are transferred via the 4 byte output communication
object “Meter reading”.The application software “Tariff meter/1.1” has five
meter reading objects altogether, one for each of the four tariffs and one for
the total.The application software “Combination meter/1.1” has one object for
the active energy and one for the reactive energy.The transmitted data
correspond to the values that are displayed on the LCD display.
The sending behaviour of these objects is defined in the parameter window
“Meter readings”.
Object type Measuring range Resolution Unit
4-Byte 0 ..999 999 990 10 Wh (varh) Wh (varh)
Instantaneous power (active/reactive)
[EIS 10; 16 bit counter] :The 2 byte
output communication object “Instantaneous power” is used to transfer the
instantaneous power or energy consumption.The sending behaviour of
these objects is defined in the parameter window “Instantaneous power”.
Object type Measuring range Resolution Unit
2-Byte 0 ..65534 (65535 = Überlast) 1 W (var) W (var)
The application software “Combination meter/1.1” has separate communication
objects for the instantaneous active power and the instantaneous reactive
power. In addition, it is possible to transfer the reactive power as:
●a 2 byte object [EIS 10; 16 bit counter] (see above) with a separate
“Reactive power type” [EIS 1; switching] object in order to transfer the type
of reactive power.
Telegram value “0”:inductive reactive power
Telegram value “1”:capacitive reactive power
●or as a 4 byte object with sign [EIS 11; 32 bit counter] .
Object type Measuring range Resolution Unit
4-Byte – 65534 ......+ 65534 1 var var
If the actual instantaneous power lies above 65534 W (var), the value 65535
(FF FFhor 7F FF FF FFhfor the 4 byte object) is sent as an “overload signal”.
Request meter reading
[EIS 1; switching] :The read request for the current
meter readings of the EIB Delta-Meter is transferred to the meter via the 1 bit
input communication object “Request meter reading”. Once a request signal
telegram with the value “1” has been received, the meter reading is stored
and sent on the bus once the transmission delay TWhas elapsed (if selected).
This sending behaviour is defined in the parameter window “Meter readings”.
The communication object is only visible if the option “Send on request” is
selected.
Telegram value “1”: Send meter reading
“0”: No function
Switch tariff
[EIS 14; 8 bit counter] :The 1 byte input communication object
“Switch tariff” enables the control of four different tariffs of an EIB Delta-Meter
tariff meter via the ABB i-bus®EIB.On receipt of a valid object value (1, 2, 3
or 4), the meter switches to the required tariff. Once the transmission delayTW
has elapsed (if selected), the current data of the old and new tariffs as well as
the total of all the tariffs at the time of the change are sent on the bus.

ABB i-bus®EIB
Telegram value “1”: Switch to tariff 1
“2”: Switch to tariff 2
“3”: Switch to tariff 3
“4”: Switch to tariff 4
“other values”:no function
Approximately 6 seconds after a reset or bus voltage recovery, the actual
status of the communication object “Switch tariff” is queried via the bus.
Once a response has been received, a corresponding tariff change is carried
out and the current data and total of all the tariffs is sent on the bus.
However, if there is no response after approximately a further 4 seconds, the
meter switches to the last selected tariff (prior to the reset or bus voltage
failure) and the data is sent.To guarantee this function the‘update flag’ of the
“switch tariff” communication object must be set to active (default setting).
The tariff control signal from the electricity supply company can be sent on
the EIB by connecting a tariff decoder unit to a binary input via potential free
contacts (1 per tariff).The required 8 bit value for switching the tariffs can be
generated using a binary input Serie ET/S 6.xxx.x together with the
applikation software “Value Edge Cyclic/3”.
Acknowledgement “Meter reading received” [EIS 1; switching] : If the
function “Active acknowledgement “Meter reading received”” is activated, the
EIB Delta-Meter expects an acknowledgement from the receiving EIB
devices after each transmission of a meter reading.This confirms that the
data has reached the recipient. If no acknowledgement is received after
approx. 2 seconds after the meter reading has been sent, the transmission is
repeated.The 1 bit input communication object is only visible if the
parameter “Active acknowledgement “Meter reading received”” in the
parameter window “Meter readings” is activated.
Telegram value “1”: Meter reading received
“2”: No function
Communication fault [EIS 1; switching] :If the EIB Delta-Meter has not
received a telegram at the communication object “Acknowledgement “Meter
reading received”” after sending the meter reading twice (see above), a
telegram is sent from the 1 bit output communication object “Communication
fault” to signal that there is a transmission fault. If a subsequent transmission
of the meter reading is acknowledged correctly, this error message is
removed.The communication object is only visible if the parameter “Active
acknowledgement “Meter reading received”” in the parameter window “Meter
readings” is activated.
Telegram value “1”: Communication fault
“0”: No communication fault
Fault [EIS 1; switching] :The 1 bit output communication object “Fault”
sends the state of the EIB Delta-Meter via the ABB i-bus®EIB in the form of
a group error message.An error message can have several causes and can
be decoded with the help of the communication object “Status byte” or by
reading out the error codes in the meter (see section 3.7).The sending
behaviour of these objects is defined in the parameter window “Status”.
Telegram value “1”: Fault
“0”: No fault
Fault acknowledgement [EIS 1; switching] :The 1 bit input communication
object enables the EIB Delta-Meter to be reset after an error has occured
and is only visible if the parameter “Fault acknowledgement” in the parameter
window “Status” is activated.The error message is only reset after an
acknowledgement if all the errors have previously been rectified.
Telegram value “1”: Reset error message
“0”: No function
