MODEL BGUS/BGUS-D • SG/SG-D OPERATOR INSTALLATION GUIDE

VENT PLUG INSTALLATION

Gear reducers used in LINEAR gate operators will have pinned vent plugs installed prior to shipping in order to keep the oil from spilling out during transportation. During installation this pin should be removed to allow proper ventilation. See the illustrations below.

LIMIT CAM ADJUSTMENTS

The limit cams for all models of barrier gate operators have been pre-set at the factory for approximately 90 degrees of motion. If you need to adjust this further, please follow the directions below. If the arm reverses just after you attempt to open it, you may need to adjust the open direction current sensor one turn higher. Refer to Page 9 for details of current sensing adjustment.

1.For more downward travel, loosen the wing nut on the LSC-1 (down) limit cam and rotate the cam slightly in the “B” direction.

2.For less downward travel, loosen the wing nut on the LSC-1 (down) limit cam and rotate the cam slightly in the “A” direction.

3.For more upward travel, loosen the wing nut on the LSO-1 (up) limit cam and rotate the cam slightly in the “A” direction.

4.For less upward travel, loosen the wing nut on the LSO-1 (up) limit cam and rotate the cam slightly in the “B” direction.

ELECTRICAL CONNECTION AND ADJUSTMENTS

Power supply must be of correct voltage and phase.

Always follow national and local electrical codes when wiring and use a qualified electrician.

Always disconnect power from operator before servicing. Keep clear of gate arm during operation.

All LINEAR gate operators are supplied with a power disconnect switch to turn on and off the power supply available to the operator. Incoming power should be brought into the operator and connected to the labeled pigtails in the disconnect box, following wiring specifications on Page 4. A wiring connections print can be found on the inside cover of the operator.

Proper thermal protection is supplied with the operator. The motor contains a thermal overload protector to protect from overheating the motor due to overload or high-frequency operation. This overload will reset automatically after the motor cools down.
