11.3 Configure the Relay Driver Outputs (Switching Outputs)
NOTE: All the explanations in this section are based on the configuration of switching outputs, be-
cause the parameterization is independent of whether the alarm devices are actuated directly via
the switching output or via a connected relay module. When relay driver outputs are described in
the following, the information also applies equally to the switching outputs.
Before connecting and configuring the relay driver outputs, be sure that no alarm devices are con-
nected to the relay contacts. Otherwise, it would be possible for unnecessary alarms to be trig-
gered. Also make sure that the relay driver outputs have been connected properly.
Before the relay modules or other approved alarm devices or units are connected to the relay driv-
er outputs, turn off the voltage to the system. Then check to make sure that the required
MGO modules are present in the system in the slots provided for them. Then make the cable or
plug connections to the relays or relay modules to be actuated. The alarm devices (or other de-
vices to be actuated) should not be connected to the relay contacts until after the relay driver out-
puts have been configured. Otherwise, false alarms could be triggered.
Then turn the voltage back on. After the system has been turned on, the message
“AUER SUPREMA MDO Module” and the current software and hardware revision nos. appear on
the display of the front panel (MDO module).
The module then performs a self-test and starts the system with the message “system start in
progress”. After the system has been started successfully, the number of inputs corresponding to
the plugged-in MAI modules appears in the “Measure/List” menu.
NOTE: If this procedure is not over in 5 minutes, check the installation again and, if necessary,
call in an MSA service technician to correct the problem.
Configure the Relay Driver Outputs
Up to 40 relay driver outputs can be actuated per each plugged-in MGO module. Be sure that the
first 8 relay driver outputs in the system are permanently assigned to the common alarms. The
other relay driver outputs (starting with relay driver output 9) can be configured as desired.
The relay driver outputs are configured in the “Setup/Relay Outputs” menu. The individual options
are described below.
NOTE: The name of the menu or of the input or option field used by the PC operating software is
given in parentheses.
Option field “Relays” (“Output number”): Choose the number of the relay driver output to be con-
figured.
Option field (beside “Relays” field) (“kind of switching”):
NOTE: When the relays are inhibited by using the LOCR connection on the MRC TS module, the
switching direction selected in the “open circuit/closed circuit” option field must agree with the
Normally energised When having been set (alarm, failure), the relay driver output gives out
a LOW signal, i.e. the connected relay is de-energised (normally ener-
gised principle)
Normally de-energised (Relay is de-energised) When having been set (alarm, failure), the relay
driver output gives out a HIGH signal i.e. the connected relay is ener-
gised (normally de-energised principle)
