LL Actuator - Installation Manual - 2020-11 9
4.4.5 Hand wind mounting and operation
1. Make sure when mounting the actuator that there is space enough between the rear adapter and any
object behind it to allow the hand wind to be operated!
2. To be able to operate the hand wind, remove the cover plug placed over the hand wind input (a).
3. Next, move the extension tube by turning the hand wind input hexagon socket (b) using a 6 mm male
hexagon key (c).
4. The maximum torque required to move the extension tube at the fully rated actuator load using the
hand wind is typically 4-6 Nm (35-50 in-lb).
Always make sure to switch o the power to the actuator before using the hand wind.
Do not apply higher torque than 10 Nm (88 in-lb) to the hand wind input.
Never run the extension tube in to the end of stroke as that may damage the actuator.
Never use any type of drill or power tool to operate the hand wind.
4.4.6 Mounting of optional external limit switches
1. The external limit switches are mounted in the two slots (a) at the bottom of the cover tube.
2. Put the sensor (b) into one of the slots and and lock it at the desired position by turning the clamp
screw 45 degrees (c).
If the sensor is mounted in the immediate vicinity of magnetic components, the
switching characteristics of the sensor may change.
