10.6.8 Air actuator in the event of fault
Parameter 50
This parameter decides whether the air actuator can
be activated externally via the input at terminal 2 in the
event of a fault lock-out.
Parameter 50 = 0: cannot be activated. The air actuator
remains closed in the event of a fault lock-out. It cannot
be activated externally via the input at terminal 2.
Parameter 50 = 1: can be activated externally. The air
actuator can be activated externally via the input at ter-
minal 2 during a fault, e.g. for cooling.
