Adjustment of the cams
Under normal conditions, the actuator may only be operated with the closed cover.
If work is performed on the actuator with the removed cover, the supply and control voltage must
first be disconnected. Adjustments, which need to be done in the energized state, should be carried
out with special insulated tools.
How to do it: Tolling: One special plastic wrench (is supplied together with the actuator). The
wrench is tied together with the motor by using one plastic clamp.
To move the cams, introduce the special plastic wrench in the hole of the cam and turn it round
(see both options on the enclosed pictures).
