3 Field of application / Function range
multicount 3D6-0-LCD-EP-.../3D6-1-LCD-ES-... is a compact, easy-to-use energy meter counting active as
well as reactive energy (for consumption and recovery).
This energy meter was designed in accordance with the standards DIN EN 61036 (IEC 1036),
DIN EN 61268 (IEC 1268) and the requirement specification 2.0 revision 12/97 by the German Electricity
Association (VDEW)
Dual-tariff meter function (HT/LT) (multicount 3D6-1-LCD-ES-... only)
Consumption during high tariff and low tariff times is saved separately. Switching from high to low tariff times
and vice versa is either carried out by means of a digital signal to be applied externally, e.g. from the energy
supplier, or via an internal clock. A display flashing on the front of the device indicates which tariff is active at
the moment. When operated with the KBR Energy Bus, switching over can also be carried out centrally via the
Multimaster or PC.
Convenient operation and display
The LCD serves to either display the measured values directly or enter the respective parameters and confi-
guration data. In addition, six LEDs serve to show the status and monitor the functions. Four buttons facilitate
clearly structured navigation through the menus.
For 100 to 500 V networks
The multicount 3D6-0-LCD-EP-.../3D6-1-LCD-ES-... can be applied in three-wire as well as four-wire
networks. The unit can be implemented in 100 V as well as in 500 V networks for direct measurement. Using
a transducer adaptor, up to 700 V can be connected to the meter. Higher voltages can only be connected via
external voltage transformers; primary and secondary voltage can be freely programmed. The measuring
voltage inputs of the device measure directly, i.e. they are not metallically separated by a voltage transformer!
For energy supply networks with outer conductor connected to the earth potential, suitable suitable control gear
with electrical isolation (e.g. voltage transformer) must be used.
x/5A or x/1A freely programmable
The measuring inputs for current must always be fed via current transformers, while the transformer ratio is
programmable. The primary current value as well as the secondary current value can be selected.
Programmable pulse output
Active energy or reactive energy proportional pulses can be output via a programmable output laid out as S0
interface. The pulse output type (in proportion to active or reactive energy for consumption or recovery) as well
as the pulse values (number of pulses per kWh or per kVArh) and the pulse length can be configured. These
pulses can be processed fo example by a master system for data acquisition or optimization, a maximum-
demand monitor or a central process control.
Each pulse is visualized by a flashing LED.
Serial port for connection to the KBR Energy Bus (multicount 3D6-1-LCD-ES-... only)
The multicount 3D6-0-LCD-EP-....has a serial port (RS485) is designed for conveniently configuring the
instrument via computer and optional software.
The interface offers the possibility to equip the multicount 3D6-0-LCD-EP-... with the funtionality of the
multicount 3D6-1-LCD-ES-... with an optionally available upgrade.
The multicount 3D6-1-LCD-ES-... has a serial port (RS485) for operation with the KBR Energy Bus.
A large amount of information that cannot be shown on the display can be read from the device via the Energy
Bus.
This allows both the online measured values for phase voltages, phase currents, individual power factors and
individual performance, as well as an entire series of data to be read out from the long-term memory.

EDEBDA0145 / 4709-1 GB
Extensive memory functions
In addition to its counter functions, the multicount 3D6-1-LCD-ES-... offers extensive storage functions.
-4-quadrant load profile memory to record the cumulated active and reactive power
- Memory to record the daily energy values for 365 days
- Memory for the measuring period maximum of the previous month
-Event memory (4096 entries), for logging actions of the meter such as mains failures,
tariff switching actions, delete functions, and many more.
These memory functions are exclusively available via the KBR Energy Bus..
Synchronization
For synchronization of the load profile memory, a digital input is integrated into the multicount 3D6-1-LCD-
ES-... to connect the the synchronization signal of the energy supplier, for example. Synchronization as well
as high / low tariff switching can be controlled centrally via the KBR Energy Bus as well as via the internal clock.
Software (optional)
A number of software products that can be run on most Microsoft® Windows® operating systems is available
for the convenient programming and storage of long-term data.
Separate power supply
The device requires a separate auxiliary voltage for operation (see nameplate).
For questions about this device or about our software products please don’t hesitate to contact us. We will be
glad to assist you.
Please see the cover of this manual for your contact.
4 Connecting the multicount 3D6-0-LCD-EP-.../3D6-1-LCD-ES-...
4.1 Installation and Assembly
The housing of the multicount 3D6-0-LCD-EP-.../3D6-1-LCD-ES-... has been designed for wall moun-
ting on 35 mm DIN rail. The module is snapped on the mounted DIN rail.
For the wiring of the pulse output, we recommend to use twisted pair and shielded material exclusively to avoid
disturbance (e.g. installation line I-Y(ST) Y 2x2x0.8mm, while the shielding may only be connected on one
side).
During installation, please also observe our notes on safety measures against overvoltage and lightning in
chapter “Protective Measures” of this manual.
aCaution
The control voltage as well as the applied measuring voltage of the device must
be protected by means of a back-up fuse.
When connecting the current transformers, the direction of the energy flow and
the correct assignment to the voltage paths must be observed!

Rotary field:
As soon as the multicount 3D6-0-LCD-EP-.../3D6-1-LCD-ES-...cis connected to the mains, it will auto-
matically detect the rotary direction.
Current transformation connection:
Energy flow direction:
When mounting the transformers, observe the current flow or energy flow direction. If the current transformers
are inserted the wrong way, the current will have a negative sign for active power input. In this case,
interchange the pins of the terminals k and I of the affected transformers.
Assigning measuring voltage input / current transformer input:
The current transformer on terminal 20/21 (k1/l1) must be arranged in the phase where the measuring voltage
for the terminal 10 (L1) is measured. The same applies to the other transformer and measuring voltage con-
nections.
bNote

6 Measuring values of the multicount 3D6-0-LCD-EP-.../3D6-1-
LCD-ES-... and their representation
The following section provides an overview of the measuring values of the multicount 3D6-0-LCD-EP-.../
3D6-1-LCD-ES-... and their representation on the device. The respective measuring range switches
automatically in the display.
6.1 Display of active or reactive energy measurement
It can be seen in the LC display through T1 or T2 whether the period is high or low tariff. The currently active
tariff is indicated by flashing of T1 or T2. (Two-tariff counter function only fori multicount 3D6-1-LCD-ES-
...)
The five digit places and the Prefix LEDs serve to show the instantaneous meter count.
As long as the meter count does not exceed 9999kWh, the entire meter count is displayed in one menu. From
10 MWh the display is divided into several menus so that more than five places can be read. These menus can
be called up using the A key. The overall value results from simply writing out the individual values one after
another.
Exampel:

6.2 Display of power measurement
The entire active power measurement is marked with a"p"in the first position, "s"tands for total apparent pow-
er measurement and "q"for total reactive power measurement.
Active power during energy consumption is displayed without polarity sign, during energy recovery
(multicount 3D6-1-LCD-ES-... only) with a negative polarity sign.
For inductive reactive power, the measured value is preceded by an "i" capacitive reactive power is iden-
tified by a "c".
For the display of the measured values themselves the same principles apply as for the display of active and
reactive energy. The output measuring value must be multiplied with the respective display significance ”Kilo”,
”Mega” or ”Giga”, depending on the active LED.
Display of active power in W, kW, MW, GW, the apparent power S in VA, kVA, MVA, GVA and the reactive
power Q in Var, kvar, Mvar, Gvar.
6.2.1 Display for energy consumption or recovery (multicount 3D6-1-LCD-ES-... only)
Whether energy is recovered can be determined by means of the polarity sign for the active power and the
continuous meter.
6.2.2 Display of the power factor
If the power factor λis measured, this is indicated by “PF” (power factor) in the first of the two places in the
display.
by definition the power factor is the relationship of the active power to apparent power
In contrast to the cos ϕ. for the power factor λthe proportion of distorted reactive power is included in the
calculation.
