Maintenance
Exchanging the actuator head
The part-turn actuator is pre-stressed and must be held in position!
Unscrew enclosure cover (1), turn locking plate (2) to the right, pull off actuator
head (3).
Insert new actuator head (3) as far as it goes, turn locking plate (2) to the left,
screw on enclosure cover (1).
Part-turn actuator 3SE5000-0AH00 (left or right-hand switching)
Setting the actuator head for either left or right-hand switching (at the fac-
tory)
Actuator plunger (4) turned to the left by 90° = left-hand switching.
Actuator plunger (4) turned to the right by 90° = right-hand switching.
