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

-8-

ELECTRICAL CONNECTION AND ADJUSTMENTS

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 speciﬁ cations 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.

Power supply must be of correct voltage and phase.

Always follow national and local electrical codes when wiring and use a

qualiﬁ ed electrician.

Always disconnect power from operator before servicing.

Keep clear of gate arm during operation.

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.

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.

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.
