Torque Limiter Adjustment
Before adjusting the torque limiter, make sure the gate is in good working condition. With the gate disconnected from the gate arm, one person should be able to move the gate by hand. Be certain the gate moves freely and without binding throughout its travel.
Torque limiters are set light at the factory. They must be adjusted during installation, preferably after limit cams have been manually set. With the gate arm and gate attached, adjust the torque limiter tight enough to keep it from slipping during normal operation.The inherent entrapment protection (current sensing) feature must activate prior to any slipping of the torque limiter.
✓NOTE: The open and close current sensing may need to be adjusted before performing the following two steps. See Page 13.
To adjust the torque limiter in a Model VS-GSWG:
1.Loosen the set screw on the adjustment nut.
2.Cycle the gate open and closed while observing the torque limiter action. TURN THE OPERATOR POWER DISCONNECT SWITCH OFF BEFORE MAKING ANY ADJUSTMENTS.
To increase the torque, turn the adjustment nut clockwise one fl at, or 1/6 turn, at a time until desired output is obtained.
To reduce the torque, turn the adjustment nut counterclockwise one
flat, or 1/6 turn, at a time until desired output is obtained.
3.When fi nished, tighten the set screw to lock the adjustment nut in place.
