IDEC SmartRelay Manual
IDEC SmartRelay expansion modules, operating states
IDEC SmartRelay expansion modules know three operating
states: The LED is lit green, red or orange.
FL1B-CAS2, communication states
The FL1B-CAS2 knows three communication states: The
LED is lit green, red or flashes red/yellow.
FL1B-CAS2, behaviour on communication failure
• If the FL1B-CAS2 voltage fails, communication between
the IDEC SmartRelay system and the expansion
modules, which are arranged to the right of the FL1B-
CAS2 expansion module, is interrupted.
Recommendation: Position FL1B-CAS2 on the far right-
hand side!
• If communication is interrupted, the switching outputs are
reset after about 40 to 100 ms.
