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

Control Board L.E.D. Indicators:
OPEN 

This indicator is lit when an open signal is present. This signal can come from such devices as button 
stations, radio receivers, keypads and telephone entry systems.

This indicator is lit when a closed signal is present. This signal typically comes from three-button stations.

This indicator is lit when there is a break in the stop circuit. Make sure there is a stop button wired in and 
working properly.

This indicator is lit when a signal from a single-button station or radio receiver is present.

This indicator is lit when an open/reset signal is present. This signal can come from loop detector or other 
switch wired to oepn/reset input terminal #50.

OPEN OBST 

This indicator is lit when an open/reset signal is present. This signal can come from a loop detector or 
switch connected to terminal #50.

This indicator is lit when a reversing signal is present. This signal is generated by a loop detector wired 
to the safety loop terminals.

SHADOW LOOP  This indicator is lit when a reset signal is present. This signal is generated by a loop detector wired to the 

reset loop terminal #11.

These indicators are lit when the open #1 limit switch is activated on a right-hand operator, or the close 
#1 switch on a left-hand. If this indicator is lit and the gate is not in its full open/closed position, the limit 
may need adjusting or the limit switch may need replacing.

 

These indicators are lit when the close #1 limit switch is activated on a right-hand operator, or the open 
#1 on a left-hand. If this indicator is lit and the gate is not in its full open/closed position, the limit may 
need adjusting or the limit switch may need replacing.

Motor Board L.E.D. Indicators:
NON LABELED  One of these two indicators will be lit when the motor is running the gate open, and the other is lit when 

the motor is running the gate closed.

This indicator is lit when the motor is running in either direction. This function is not used on this operator.

Indicates AC power is supplying the unit.

Indicates the operator is running on batteries.

Indicates batteries are being charged. Light goes out when batteries reach 90% of full charge.

Operator is in open then lockout stage.

Flashes when controls/motor are in lockout mode.

The optional surge protector should be connected to 
any inputs that have an accessory connected to it. This 
includes the 3-button station, so it must be connected 
to 1, 2A and 3 in all cases. The green wire connected to 
ground, which is electrically the same as terminal 4. The 
red wires connect to terminals 2A and 24VDC+. This 
will cause the 2 amp fuse to blow if this section of the 
module becomes shorted. With any of the other inputs 
connected to the surge protector, if their protection line 
becomes shorted due to a surge over the rating of the 
module, the corresponding LED on the main board will 
remain lit, causing a constant signal to the controller. If 
this is found, please replace the entire surge protector 
with a new unit.
