0: deactivated
Evaluation of motor protection relay or motor protection switch
1: Thermal protection high-activated (error "F53" when open)
2: Thermal protection low-
active (error „F53" when closed)
Evaluation of auxiliary contact compressor contactor
3: Fault monitoring through switch-on feedback from the compressor
contactor normally open contact.
4: Fault monitoring through switch-on feedback from the compressor
contactor normally close contact.
Choice 3 or 4:
When a compressor is switched on, feedback is expected at the digi-
tal input after 60 seconds at the latest.
If this feedback does not come, fault F53 is triggered.
