IFM Electronic AS-interface AC2501 Montageanleitung Seite 7

Supply the slaves with voltage via the AS-i power supply. Addressing is
carried out via the IR addressing cable E70211.
When the ifm AS-i power supplies SL are used the communication can
be deactivated via a plug on the power supply.
Function check inputs
In case of a fault the high or low activity (NO or NC principle) of the
function check inputs can be set separately for each input via a para-
meter bit. In case of a fault the red LED of the corresponding input
lights and in addition LED 2 (FAULT) flashes.
