Turn-on Behavior and Failure Behavior MAO Module
After turn-on, at the analog outputs a 0 mA signal is issued for 10 - 15sec.
If the settings for FREEA / FREEB are done locally on the MGO or MAO modules (position INT),
or if no such modules are installed in the rack, then the switches FREEA / FREEB on the MIB have
to be set to the ON position.
Configuration MAT Module
Two solder bridges are provided for each input on the bottom of the circuit board for 3 or 5 wire
operation of the sensors:
CAUTION!
The solder bridges for 3 wire operation must only be closed when passive detectors (MPI module)
are connected. For 5 wire operation with active transmitters (MCI module), the solder bridges must
be open!
