LED indicationLED P: (power supply): On = operating, fast flash = cold start
LED 1: (collective alarm): On = internal fault, flashing = no fieldbus connection
LED 2: (operating mode): flashing 1 (1:1 ratio) = active, normal operation; flashing 2 (7:1 ratio) = active, simulation
LED 3: (status fieldbus): flashing = fieldbus receive channel active
LED 4: (status fieldbus): flashing = fieldbus response channel active
LED 5: (status service bus): flashing = service bus receive channel active
LED 6: (status service bus): flashing = service bus response channel active
Relative humidity95 % non-condensing
