1. Setting
Manual operation
Pull over the lever toward hand wheel until lever stands perpendicularly.
If lever does not stand perpendicularly, pull over it again turning hand wheel slowly.
There is casting mark to indicate rotating direction on hand wheel
Clockwise is close direction and counter clockwise is open direction.
No need to position the lever to original for electrical operation.
Once electrical power is on, the lever automatically return its original position by internal clutch mechanism.
Limit switch setting
Pull over the lever for manual operation and turn hand wheel to move actuator full close (Or open) position
Loose the bolts tightening cam by L-wrench, and turn CLS(Or OLS) cam to CW (or to CCW), so that cam may hit the lever of close (Or open) limit switch.
Then tighten the bolt by L-wrench
Torque switches
Torque Switches are set by factory before delivery and therefore no need to set the switches again, but just do as follows for check if switches functions well.
Push the lever of close switches by screw driver until it sounds "click" then actuator should stop immediately. If it stops, switches work well.
Check open switches as per just same with above.
No guaranty in performance once these switches are set again.
Before setting, if it is really necessary to adjust, please consult with factory.
