4 Initial commissioning
For initial commissioning of the EM, proceed as follows:
1. Connect the VBus®cable
2. Establish mains connection
3. Adjust the sub-address (SA)
4. Register the module in the controller (see con-
troller manual)
Note
To register the module in the controller, use
the same number that has been selected as
sub-address! Example:
If SA = 1, register the EM as module 1 in
the controller.

5.2 Display channels
Error code display
EC
Error code
Display range: 0,2
0 = OK
2 = Bus error (there has been no bus communica-
tion for approx. 1 min)
Version compatibility display
VC
Version compatibility
Display range: 0,4
This channel indicates if the controller connected has
been recognised by the module.
If 0 is indicated, the controller has not been recog-
nised or the bus communication is faulty.
If 4 is indicated, the extension module has recognised
the controller and is functioning normally.
Display of sensor temperatures
S1 … S6
Display of measured values
Display range: -40 … +260 °C
Only if a sensor is connected to the corresponding
terminal, will a value be displayed.
In the case of a line break or if no sensor is connected,
9999 will be displayed.
In the case of a short circuit, 0 will be displayed.
Display of speed
R1 … R5
Display of speed / status
Display range: 0 … 100 %
These channels indicate the current speed values of
the relays. R5 is a potential-free relay not suitable for
speed control. Therefore, its status is indicated with
0 % or 100 % respectively.
Display of the software version
PG
This channel indicates the version number of the
firmware.
Display of the version number
VN
This channel indicates the version number of the
hardware.
5.3 Adjustment channels
Manual mode
M1 … M5
Adjustment range: OFF,Auto, On
Factory setting:Auto
In the channels M1 to M5, the corresponding relays
can be switched on or off, or set to automatic mode
manually.
Manual mode
MM
Adjustment range: 0 … 5
Factory setting: 0
The adjustment in this channel determines which re-
lays are switched on when the slide switch below the
display is set to I.
0 = Relay 1 on, all others off
1 = Relays 1 and 2 on, all others off
2 = Relays 1 and 5 on, all others off
3 = Relays 1, 2 and 5 on, all others off
4 = Relays 1 and 4 on, all others off
5 = Relays 1, 4 and 5 on, all others off
Selecting the sensor type
T1 …T6
Adjustment range: 0 … 4
Factory setting: 0
In this menu, a sensor type can be selected for each
sensor input.The following adjustments are available:
0 = Resistance (the measured resistance will be dis-
played independent of the sensor type connected)
1 = Pt1000
2 = KTY
3 = PT500
4 = RTA (remote control)
Note
The adjustments made in the channels
T1 …T6 only determine the display of the
measured values in the channels S1… S6 of
the extension module.
ÎAdjust the sensor type in the controller
connected as well!
Allocating a sub-address
SA
Adjustment range: 1 … 15
Factory setting: 1
In this channel, a sub-address can be allocated to the
module. The in- and outputs of the module will be
displayed with the sub-address number in the control-
ler connected.
Note
To register the module in the controller, use
the same number that has been selected as
sub-address! Example:
If SA = 1, register the EM as module 1 in
the controller.

6 Troubleshooting
If a malfunction occurs, the display symbols will indi-
cate an error code (see chap. 3.4.2).
fuse holder
The device is protected by a fuse. The fuse holder
(which also holds the spare fuse) becomes accessible
when the cover is removed.To replace the fuse, pull
the fuse holder from the base.
WARNING! Electric shock!
Upon opening the housing, live
parts are exposed!
ÎAlways disconnect the
device from power supply
before opening the housing!
Operating control lamp is permanently off.
If the control lamp is permanently off, check the
power supply of the device. Is it disconnected?
yes
The fuse of the device
could be blown.The
fuse holder (which
holds the spare fuse)
becomes accessible
when the cover is
removed.The fuse can
then be replaced.
Check the supply line
and reconnect it.
no
In the senor temperature display channels, line breaks
or short circuits of the sensor cable will be displayed.
Error messages for sensor faults are only indicated in
the controller connected.
Disconnected temperature sensors can be checked
with an ohmmeter. Please check the resistance values
correspond with the table.
