Operation Manual SUPREMA
8. System Expansions
will also be needed. The new MAI modules can be plugged in while the system is running. To
avoid alarm and error messages, the connected relays
(see section 5.7.2 Relay Inhibit) must
be locked. The new inputs are recognized by the system; as in case no. 1, however, they must
be preadjusted (passive sensors only), configured, and calibrated. These steps are described
in detail in
sections 6.3.1 Preadjust the Passive Sensors and, 6.3.6 Configure the Sensors and
6.5 Preliminary Calibration.
3. All of the existing MAI modules are assigned, or the number of free inputs is < the number of
new inputs to be connected.
No free slots for additional MAI modules are present in the existing
racks.
In this case, additional MAI modules (one MAI module required for every 8 sensors) with the
associated MPI/MDI modules are required, depending on the number of new sensors to be
connected. Additional MAT/MAT-TS/MUT/MGT40-TS modules will also be needed. In addition,
one or more new racks and the necessary CAN bus connecting cables are required.
Always turn off the voltage when connecting a new rack. After the supply voltage has been
turned off, mount and install the additional racks. The connection of the racks and the required
configuration changes (MIB module) are described in
sections 5.5 Systems with Several Racks
and 5.3.1 Configure the MIB Module. Be sure to choose the correct CAN bus Bit rate and CAN
node no.
Note: Whenever you connect additional sensors, always make sure that the voltage
supply to the system is still adequate
(see section 5.11.1 Calculation of the Required
Power Supply). If necessary, install a voltage supply which meets the new
requirements.
8.2 Connection of Additional Relay Driver Outputs
8.2.1 Additional Relay Connections
One SUPREMA system can provide a maximum of 512 relay driver outputs.
One MGO module makes 40 relay driver outputs available. A maximum of 10 MGO modules
can be plugged into one rack. This number, however, is based on the use of at least one
additional rack containing the appropriate MAI modules, which make it possible to connect the
sensors.
One of the following procedures must be followed, depending on the extent to which the system
has already been expanded:
1. A sufficient number of free relay driver outputs are still present on an existing MGO module.
a) Until now, only the common alarms of the MRO module plugged into the rack have been
used.
In this case, the MRO-8 module must be replaced by MRO-8-TS modules, which are connected
with ribbon cable via MRC-TS and MUT modules to the MGO module plugged into the rack
(see
Figure 5-33: Connection Diagram od the MRC-TS and MRO-8-TS Modules). 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 5.7.2 Additional Relay Outputs.
b) MRO-8-TS modules are already installed.
In this case, the connection can be made to existing MRO-8-TS modules; otherwise, additional
MRO-8-TS modules must be installed.
