Motorized Rotary Actuator

4.3 Principle of operation

4.3.1 Manual adjustment

By turning the crank wheel the position of the actuator can be adjusted. This also turns the
motor.
Only carry out manual adjustment when the motor is not in motion. If a positioner is used, the
actuator will automatically move back to the original position. Therefore only carry out manual
adjustment when the actuator is disconnected from the power supply.
It is not necessary to use an extension for a greater mechanical advantage during manual
operation. Use of excessive force can damage the equipment.

4.3.2 Removing the cover

Disconnect the device from the power supply before starting any maintenance or adjustment
work.
● Loosen the four socket-head screws at the corners of the cover
● Grip the cover and lift to remove
