IFM Electronic AS interface AC2616 Notice De Montage page 13

Operation AC2616
Check the safe functioning of the unit. Display by LEDs:
• LEDs yellow (analog 1 / 2) on:
LEDs yellow (analog 1 / 2) flashing: analogue signal outside the
LEDs yellow (analog 1 / 2) out:
• LED green (A/D power) on:
• LED green (AS-i) on:
• LED red (FAULT) on:
LED red (FAULT) flashing:
* The LED state reflects the status of the voltage from which the sen-
sor is supplied, i.e. it depends on the selected link position.
**Periphery fault
A periphery fault is indicated if at least one of the signals analogue
1 or analogue 2 is outside the value range or nothing is connected
to at least one analogue channel.
