The torque scale sectors are factory-set and are a reference for
cam calibration. Do not modify their position or you will not be
able to accurately adjust the torque limiter anymore.
Actuators are calibrated and tested in factory according to the
torque stated on orders. If no torque is specified, the actuator is
supplied with the limiter calibrated to the maximum output torque.
In both cases, the torque limiter can still be adjusted if necessary.
To adjust the torque limits, set the tip of the cams to match the
required percentage of maximum torque
1. For the closing
torque limit, set the
tip of cam (1) on the
required percentage
on the CLOSE scale
2. For the opening
torque limit, set the
tip of cam (2) on the
required percentage
on the OPEN scale
On the opposite figure, the
closing torque limit is 100%
and the opening torque
limit is 70%.
How to adjust a cam
1. Turn the setting screw of the corresponding cam with a flat
blade or a Philips screwdriver.
