The detection of short-circuits and line interruptions is ensured – similar to the sensor
inputs.
In operating mode 2 (intLC), changeover between the 2 internally defined setpoints W1
and W2 can be implemented by means of an external (potential-free) contact.
The settings described under Input 3 can also be made from a BACS connected to the
AZL5 via RS-232 and bus interface.
An external predefined setpoint exists with Int LC bus.
An external predefined load exists with Ext LC bus.
