MODULAR SAFETY INTEGRATED CONTROLLER MOSAIC
Channel configured as Redundant (Pair of sensors connected), conditions:
1.
Sensor supply overload. Input channel overload. Read value over threshold. Read value under threshold. Disconnected sensor:
When one of these diagnosis is detected the RED led relative to the channel with the problem will flash. The RED led of the other channel remains ON
(no flash). If one of the above diagnosis is detected at the same time on both sensors the RED led of the second channel will flash while the RED led of the
first channel remains ON (no flash).
2.
Read value from sensor pair out of tolerance diagnosis: both LEDs of channel pair will flash.
