Denition of terms
3 Denition of terms
Below, you will nd brief explanations of the terminology used in this manual.
Root-mean-square value:
By denition the square of the average value of a periodic or pulsating value is
referred to as the root-mean-square value. multimess D6 exclusively uses the
RMS values of pure periodic values.
Instantaneous root-mean-square value:
The value determined by the multimess D6 during its measurement intervals.
Measurement interval:
During a measurement interval, the electrical quantity “Voltage”or “Current”
of one phase is scanned. The resulting scanning spots are available for further
calculations. This interval is mainly determined by the A/D conversion.
Measuring cycle:
The measuring cycle is the time the measuring device needs in order to mea-
sure all the values recorded by the device for all three phases.
Firmware:
The operating system software implemented in the multimess D6’s microcon-
troller.
Load prole memory:
Saves the actual values of the measurment periods with timestamp.
Measurement period maximum value:
The measurement period containing the highest (maximum) value that oc-
curred.
Active/reactive power periods:
Actual active or reactive power within a measurement period.
Measurement period:
The period of time used to determine the average power demand. Typical inter-
vals: e.g. 15, 30, 60 minutes.
DIN rail
Top hat rail / mounting rail acc. to DIN EN 50022

Application/range of functions
4 Field of application/range of functions
multimess D6 is a compact, easy-to-use energy meter that records active as well
as reactive energy (for consumption and recovery).
This energy counting device was designed in accordance with the standards
DIN EN 61036 (IEC 1036), DIN EN 61268 (IEC 1268) and requirement specica-
tion 2.0 revision 12/97 by the German Electricity Association (VDEW).
Dual-tari counter function (HT/LT)
Consumption during high tari and low tari times is saved separately. Switch-
ing from high to low tari 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 ashing on the front of the device indicates which tari
is active at the moment. When operated with the KBR Energy Bus, switching can
also be carried out centrally via the Multimaster or computer.
Convenient operation and display
The LCD serves to either display the measured values directly or enter the re-
spective parameters and con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 400 V networks
The multimess D6 can be applied in three-wire as well as four-wire networks.
If the measuring value displays in the three-wire network are incorrect, a ze-
ro-point creator should be used. The unit can be implemented in 100 V as well
as in 400 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, whereby 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 po-
tential, 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 an S0interface. The pulse output type (in
proportion to active or reactive energy

Application/range of functions
for consumption or recovery) as well as the pulse values (number of pulses per
kWh or per kvarh) and the pulse length can be congured. These pulses can be
processed by, for example, a master system for data acquisition or optimization,
a maximum-demand monitor or a central process control.
Each pulse is visualized by a ashing LED.
Serial interface for connection to the KBR Energy Bus
In its default conguration, the multimess D6 has a serial interface
(RS-485) for operation with the KBR eBus.
A large amount of information that cannot be shown on the display can be read
from the device via the Energy Bus.
Thus the online measuring values of the individual power factors and the indi-
vidual power as well as a large amount of data can be read from the long-term
memory.
Extensive storage functions
In addition to its counting functions, the multimess D6 oers extensive memo-
ry functions:
4-quadrant load prole memory to record the cumulated active and reactive
power
Memory to record the daily energy values for 365 days
Memory for the previous month’s maximum measurement period
Event memory (4096 entries), for logging actions of the meter such as mains
failures, tari switches, delete functions etc.
These memory functions are only available via the KBR eBus.
Synchronization
Synchronization as well as high/low tari switching can be controlled centrally
via the KBR eBus or 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 on this device or on our software products please don’t hesitate
to contact us. We will be glad to assist you. Please see the cover sheet of this
manual for your contact address.

5 Connecting the multimess D6
5.1 Installation and assembly
The housing of the multimess D6 has been designed for wall mounting on a
35 mm DIN rail. The module is assembled to the mounted DIN rail.
Caution
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 energy ow direction and the correct assignment to the
voltage paths must be observed!
For the wiring of the pulse output, we recommend to exclusively use shielded
twisted pair material to avoid disturbance (e.g. installation line I-Y(ST) Y 2x2x-
0.8mm, whereas the shielding may only be connected on one side).
During installation, please also observe our notes on safety measures against
overvoltage and lightning in the chapter“Protective measures” of this manual.
Note
You should take the following points into consideration when connecting
the device to the three-phase network
to be measured:
- Energy ow direction
- Assigning of measuring voltage input/current transformer input
Rotary eld:
As soon as the multimess D6 is connected to the mains, it will automatically
detect the rotary direction.
Current transformer connection:
Energy ow direction:
When mounting the transformers, observe the current ow or energy ow
direction. If the current transformers are inserted the wrong way round, the cur-
rent will have a negative sign for active power input. In this case, interchange
the pins of the terminals k and l of the aected transformers.

7.2 Display of power measurement
The total active power measurement is identied by a„p“ in the rst place,„s“
identies the total apparent power measurement and„q“ identies the total
reactive power measurement.
Active power during energy consumption is displayed without a polarity sign,
during energy recovery with a negative polarity sign. For inductive reactive
power, the measured value is preceded by an„i“; capacitive reactive power is
identied 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 signicance„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.
7.2.1 Display for energy consumption or recovery
Whether energy is recovered can be determined by means of the polarity sign
for the active power and the continuous counter.
7.2.2 Display of the power factor
If the power factor λ is measured, this is indicated by “PF” (power factor) in the
rst of the two spaces in the display.
By denition the power factor is the relationship of the active power to appar-
ent power
