Torque switching: set
Valve damage due to excessive tripping torque limit setting!
→
The tripping torque must suit the valve.
→
Only change the setting with the consent of the valve manufacturer.
Once the set tripping torque is reached, the controls automatically switch off the
actuator (overload protection of the valve).
Setting via switches
Condition: Switch [S5] is in position OFF (hardware mode).

Default value: depending on the order
Setting range: in 8 steps (refer to tables), linear from 40 – 100 % of the maximum
tripping torque.
