Rotary actuators 135 • M140 • M150 • M180
20 Version 2.0 - June 2012 Operating instructions
5.1 Setting a limit position switch
You need to set the limit position switch before you can take the rotary actuator
into operation. Set the two limit position switches separately. Try out the sequence
of operations for each limit position switch once.
ATTENTION
Risk of damage from incorrectly set limit position switches
The limit position switches WE 1 and WE 2 turn off the motor in a path-dependant
way.
Do not change the factory setting if the actuator is delivered together with the flap.
• If actuator and flap are delivered separately, set the limit position switches
WE
1 (di
rection of rotation clockwise) and WE 2 (direction of rotation anti-
clockwise).
Hint: The cam disks (45.1) to (45.4) inside the cam block (40) can be adjusted
separately. The pairs of screws are allocated to each cam ring by height.
