VS-GSWG Swing Gate Operator Installation Guide

P1250 Revision X6 7-8-2011
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
fl at, 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.
