Indicators/settings

LED indication

LED 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
