Electrical connection

Connect the sensors with the terminals. The sensors must be supplied
via an external PELV or NON PELV voltage source.
All outputs (relays) must be supplied with the same voltage (e.g. 2 x
240 V AC or 2 x 24 V DC).

Operation

Check the safe functioning of the unit. Display by LEDs:
• LED green: voltage supply via the AS-i network O.K. or external
power supply o.k.
• LED yellow: input/output switched
• LED red is lit: AS-i communication error, e. g. slave address 0
• LED red flashing: peripheral fault, e.g. no auxiliary voltage
