In this case, it is necessary to install not only the additional MGO module but also additional MRO
8 TS modules, which are connected via MRC TS and MUT modules with ribbon cable to the MGO
module plugged into the rack [
→
Installation and Start-Up Guide]. 5 MRO 8 TS modules, each with
8 relays, can be connected per MRC TS module. The connection procedure is described in detail
in section 10.7 Connection of the Relay Outputs.
b] There are no free slots for MGO modules available in the existing racks.
Always turn off the voltage when connecting a new rack. After turning off the voltage supply,
mount and install the additional rack. The connection of the racks and the necessary configuration
changes [MIB module] are described in the Installation and Start-Up Guide. Take special care to
choose the correct CAN bus baudrate and CAN node no.
Additional relay modules are to be connected as described under Point 2a].
NOTE: In both cases, the relay outputs must be configured as instructed [

Installation and Start-
Up Guide].
NOTE: Whenever you connect additional outputs, always make sure that the voltage supply to the
system is still adequate [
→
Installation and Start-Up Guide]. If necessary, install a voltage supply
which meets the new requirements.
Additional Switching Outputs
As a rule, the same guidelines [especially those for the MGO module] apply here as to the con-
nection of additional relays [see section 10.7 Connection of the Relay Outputs]. Instead of the
MRO and MRC TS modules, however, MGT 40 TS modules are required, which are connected
via ribbon cable and an MUT module to the MGO module plugged into the rack [

Installation and
Start-Up Guide].
7.3 Connection of Additional Analogue Outputs
A maximum of 256 analogue outputs are provided by the SUPREMATouch, corresponding to the
maximum number of sensors that can be connected.
One MAO module makes 8 analogue outputs available. Up to 10 MAO modules can be plugged
in per rack. This is based, however, on the use of at least one additional rack containing the cor-
responding MAI modules, which make it possible to connect the sensors.
One of the following procedures must be carried out, depending on the extent to which the system
has already been expanded:
1. Not all of the 8 possible analogue outputs on an existing MAO module have been assigned. The
number of free analogue outputs is equal to the number of new analogue outputs to be connected.
No additional modules are required. The additional analogue outputs can be connected to the ex-
isting MAT or MAT TS module.
2. All existing MAO modules are assigned, or the number of free analogue outputs is smaller than
the number of new analogue outputs to be connected. A sufficient number of free slots for addi-
tional MAO modules are present in the existing racks.
In this case, additional MAO modules are required in correspondence with the number of new an-
alogue outputs to be connected.
Additional MAT/MAT TS/MUT modules are also required.
