Operation AC2516, AC2566
Check whether the unit operates correctly. Display by LEDs:
• LEDs yellow AI-1...AI-4 on:
analogue signal in the measuring range
• LEDs yellow AI-1...AI-4 flashing:
analogue signal outside the measuring range, no sensor connected or
wire break
• LEDs yellow AI-2...AI-4 out:
no sensor connected (at least one LED flashes because not all chan-
nels can be deactivated via the parameter bit P1/P2 (channel activa-
tion, channel 1 is always activated)
• LED green PWR on:
AS-i voltage applied
• LED green AUX on:
external 24 V voltage applied
• LED red FAULT on:
AS-i communication error, e.g. slave address 0
• LED red FAULT flashes:
* Periphery fault
A periphery fault is displayed:
• if at least one of the analogue signals is outside the value range
• if nothing is connected to at least one analogue channel although
the respective channel is activated
• if a wire break occurred
Operation AC2517
Check whether the unit operates correctly. Display by LEDs:
• LEDs yellow AI-1...AI-4 on:
respective channel is activated
analogue signal in the measuring range or no sensor connected (it
cannot be differentiated whether the 0 V signal is applied or
whether no sensor is connected)
(channel 1 is always activated)
• LEDs yellow AI-1...AI-4 flashing:
analogue signal outside the measuring range (outside range)
periphery fault*
