CM AS Interface, behavior on communication failure
• If the AS Interface voltage fails, communication between
the IDEC SmartRelay system and the expansion
modules, which are arranged to the right of the IDEC
SmartRelay CM AS Interface expansion module, is
interrupted. 
Recommendation: Position IDEC SmartRelay CM AS
Interface on the far right side.
• If communication is interrupted, the switching outputs are
reset after about 40 to 100 ms.
LED (RUN/STOP) is lit
