HVG LIMIT SWITCH, SETTING / WIRING INSTRUCTIONS
1.
For all HVG operators, eight conductors are required from the limit switch to the control panel.
2.
The limit switch is pre-set at the factory, to limit full travel in both directions. Fine tuning may be required in
the field, to suit conditions.
3.
To adjust the limits:
a. Loosen the cam clamp screws.
b. Depress the pinion gear, near the switch, engaging the gear teeth.
c. Rotate the cam to trip the limit switch, several inches before full gate travel, to allow the gate to
decelerate.
d. Tighten clamp screws.
e. Repeat steps "a" and "d", for each limit switch.
