The aggregates (pumps, actuators, etc.) connected to the outputs can be switched.
In the case of modulating outputs, a signal can be delivered in the relevant value range.
The application is deactivated during the wiring test. The outputs are in a defined OFF
state; safety-related functions are deactivated.
In the wiring test, the inputs and outputs are to be checked for the following faults:
• Wiring error, that is, wires have been mixed up
• Position fault, that is, wires of sensor or actuator have been mixed up
• Discrepancy between actual type of connection and controller configuration (e.g. LG-
Ni 1000 in place of DC 0...10 V)

Data backup

and all settings) can be stored in the controller. If any time later, an unauthorized per-

trolled state after commissioning.
