Detection of short-circuits and open-circuits of lines is ensured - similar to the sensor
inputs.
In operating mode 2 (intLC), changeover between the 2 internally defined setpoints W1
and W2 can be accomplished by means of an external (potentialfree) contact.
The settings described under «Input 3» can also be made from a BACS connected to
the AZL5… via RS-232 and bus interface.
Parameter: LC_OptgMode (intLC o.DDC / extLC o.DDC)
An external predefined setpoint via modbus / e-bus exists with «Int LC bus».
