3 Function
System information
This device is a part of the eNet system.
High transmission reliability at a radio frequency of 868 MHz is achieved by the transmission
behaviour and bidirectional data transfer.
The range of a radio system depends on various external circumstances. The range can be
optimised by the choice of installation location.
You can find further information about the eNet system on our website.
The device may be operated in all EU and EFTA countries.

Intended use
- Energy sensor to determine voltage, current and energy values
- Transfer of the measured values to the eNet server
- Operation with power supply RMD and receiver module RMD cover or eNet server (see
accessories)
- Installation in distribution boxes on DIN rail according to EN 60715
iThe energy sensor is not officially calibrated and may not therefore be used for invoicing
purposes.
Product characteristics
- Detection of the current and voltage of four separate circuits
- Separate calculation of the effective, idle, apparent power and the effective energy for each
measuring channel
- Event or time-controlled transmission of measured value telegrams to the eNet server
- Update of the device software
iThe parameter list is in the Internet in the documentation for this device.
Functional description
The energy sensor records and calculates various characteristic electrical values of the
connected consumers. It is possible to display these values using the visualisation of the eNet
server. All the energy sensors available in the building installation can be monitored using the
eNet server (see technical documentation of the eNet server).
Time and event-controlled data transmission
The energy sensor determines the current consumption data every 0.2 seconds. The data can
be transmitted at a configurable transmission of 1...60 minutes.
In addition, data transmission can be coupled to the change in effective output. If the effective
output exceeds a value of 1...2000 W and the deviation to the most recently transmitted value is
1...50 %, the data is transferred again, but only after at least one minute.
Default setting
Time-controlled transmission, transmission interval: 15 minutes
Event-controlled transmission:
Rel. threshold value, effective output: 10 %
Abs. threshold value, effective output: 1 W
Transferred characteristic electric values
- Current
- Voltage
- Average effective output
Interval for average formation configurable between 0.2...300 s.
- Apparent output
- Fundamental oscillation idle power
- Effective energy
The total effective energy is saved to power failure-proof memory.

oConnect the circuits to be monitored according to the energy sensor connection example
(figure 3). Connect the energy sensor behind the circuit breakers.
iThe neutral conductor must be connected separately for each monitored circuit. This
means that the circuits can also be a part of different residual current protection circuits.
4.2 Commissioning
Integrating an energy sensor into the project
The energy sensor must be read in using a system scan of the eNet server and integrated into
a project.
To do this, the eNet server must be connected correctly and connected to a computer (see the
instructions of the eNet server).
oStart the commissioning interface of the eNet server. Create or open the project into which
the energy sensor is to be integrated (see technical documentation of the eNet server).
oStart the system scan in the commissioning interface of the eNet server.
oPress one of the buttons Prog (2) of the energy sensor for longer than 4 seconds.
The status LED flashes after 4 seconds. The measuring channel is in programming mode
for approx. 1 minute.
The eNet server finds the energy sensor and displays it on the commissioning interface.
The status LED of the energy sensor goes out.
oAssign the energy sensor to the installation location using the commissioning interface.
Removing an energy sensor from the project
oIn the commissioning interface of the eNet server, delete the energy sensor from the
current project (refer to the technical documentation of the eNet server).
The energy sensor is removed from the project and the parameters reset to the default
setting.
Resetting the measuring channel to the default setting
The connection to the eNet server is disconnected and parameters are reset to default setting.
oPress the Prog button of the corresponding measuring channel for at least 20 seconds.
The status LED flashes after 4 seconds. After 20 seconds the status LED flashes faster.
oRelease Prog button and press briefly once again within 10 seconds.
The status LED flashes more slowly for approx. 5 seconds.
The measuring channel is reset to the default setting.
Resetting the device to the factory setting
oReset all the measuring channels (see Resetting the measuring channel to the default
setting).
All the status LEDs flash, as soon as the last measuring channel was reset. Device is reset
to default setting.

setting.
Transmission mode Single, Double
Basic setting: Double
The transmission of all
measured value telegrams is

Transmit effective output On, Off
Basic setting: On
Transmits the average
effective output. If negative
values are displayed, then
effective output is fed in, e.g.
via a photovoltaic system.
Transmit apparent output On, Off
Basic setting: On
Transmits the current
apparent output value.
Transmit idle output On, Off
Basic setting: On
Transmits the current value of
the basic oscillation idle
output. If negative values are
displayed, this is a capacitive
idle power. Positive values
show an inductive idle power.
Transmit absolute effective
energy
On, Off
Basic setting: On
Transmits the cumulative
value of the effective energy. If
negative values are displayed,
then effective energy is fed in,
e.g. via a photovoltaic system.
Effective energy -1073741823…1073741823
Wh
Basic setting: 0 Wh (Current
value)
Displays the currently
cumulated effective energy.
The value can be reset to 0 or
set to any other value.
Transmission interval 1 … 60 min
Basic setting: 15 min
The current consumption data
is transmitted at the interval
set here at the latest. Changes
to the effective output cause
fresh transmission, however
only after one minute at the
earliest.
Rel. threshold value, effective
output
1 ... 50 %
Basic setting: 10 %
The transmission of
consumption data can be
coupled to the change in
effective output. The basis is
always the most recently
transmitted effective output
value. If the percentage
change entered here is
exceeded, then all the
measured values are resent.
Abs. threshold value, effective
output
0 … 2000 W
Basic setting: 1 W
A lower threshold value of the
effective output can be
entered here, to avoid
frequent transmission in the
lower power range. Event-
controlled transmission is only
active above this threshold
value.

Suppression length, effective
output
0 ms … 300 s
Basic setting: 0 ms
Triggers for event-controlled
transmission are often switch-
on and switch-off operations.
In order to avoid incorrect
measured values due to
switch-on peaks, this
parameter can be used to
enter a suppression period.
The measured values are only
transmitted if the effective
output is still above or below
the relative threshold value
after the set time.
Averaging length 0.2 … 300 s
Basic setting: 1 s
In the case of effective output,
it is not the current value
which is transmitted, as with
other measured values, but
the average value. It is
possible to set the period for
average value formation here.

5.3 Troubleshooting
Negative effective output or energy values are displayed.
Cause 1: This is an energy source, e.g. a photovoltaic system, feeding in energy.
Cause 2: The energy sensor is connected in reverse polarity.
Connect the energy sensor with the correct polarity.
iIf negative idle power values are displayed, this is a capacitive idle power. Positive values
show an inductive idle power.
