VS-GSLG OPERATOR INSTALLATION GUIDE

You'll find the complete electrical circuit print inside the operator cover. The power supply must be ample and not taken from an

overloaded line, as faulty operation will result. The supply must be of correct voltage and phase. For proper wire gauge, refer to

"Wiring Specifications" on Page 32.

Proper thermal protection is supplied with the operator. The motor contains a thermal overload protector (single phase) to protect

from overheating the motor due to overload or high-frequency operation.

Refer to the photo on page 7 when following these instructions.

Adjust the limit nuts by depressing the detent plate and turning the nuts in the desired direction of travel. To allow for additional

travel in the open direction, for instance, rotate the open limit nut so that it moves to the left on the shaft. To allow for greater

travel in the close direction, rotate the close limit nut so that it moves to the right on the shaft.

Special Notes for Setting Speeds using LSO-2 & LSC-2:

Limit switches LSO-2 and LSC-2 control when the operator accelerates to maximum speed and decelerates to minimum speed.

It is recommended that LSO-2 and LSC-2 are adjusted first* so the gate slows to near stop before hitting LSO-1 or LSC-1 as

these will apply the brake upon activation.

* These are adjusted by slightly loosening the two screws which hold them in place and sliding toward or away from the center

of the limit box. Care must be taken not to adjust too close to the center as the limit nut may travel past the switch and start

accelerating at the end of the cycle.

A. Power supply must be of correct voltage and phase.

B. Always disconnect power from operator before servicing.

C. Keep clear of gate during operation.
