Range of Functions
Channels 1, 2 and 3 (single channel):
If set to single phase, only the measured value of this channel will be relayed as current
power.
If set to three-phrase, the measured value of the channel is extrapolated to a three-phase
measurement and relayed as the total current power. The output value of channel 4
would then correspond to the sum of three three-phase measurements.
For three-phase measurements, either measuring channels 1, 2 and 3 can be used as
three different meter inputs or channel 4 can be used exclusively as a single mixed chan-
nel.
However, the measuring mode of each individual channel must be set to single phase.
Meter Pulse Monitoring:
Meter pulse monitoring can only be used to monitor digital inputs.
However, the multimess D4-1 provides an analog measured value.

Measurement Period Synchronization Using an Energy Supplier
Pulse
A measurement period synchronized pulse provides for synchronicity of the measure-
ment periods from energy supplier and energy control system. This pulse is generally pro-
vided by the network operator. If there is no synchronized pulse, the device will generate
the measurement period time itself. In the overall system, synchronization is generally
performed by the eBus master.

3 Target Values for Consumption Limits
3 individually programmable rated values for power are available. Switching between the
rated values is realized by means of floating contacts (e.g. by the energy supplier). The
switching of target values can either be performed using internal timer programs or a
target value list.
