GSLG-A OPERATOR INSTALLATION GUIDE

Because gates vary in construction and may have different force requirements in the open and close directions to move, the

OSCO control board has separate Multi-turn potentiometers for adjusting in both directions independently. The adjustment

should be set light enough to maintain minimal force (50-75 lbs.) should an obstruction occur, but high enough to keep the gate

moving under normal conditions without interruption.

Prior to adjusting the operator current sensing functions, make sure the gate moves freely in both directions. A badly aligned or

poorly maintained gate may cause false triggering of the current sensor. Refer to page 9 when following the instructions below.

A factory adjustment tool has been supplied to make these adjustments easier. This tool has been taped to the control box for

your convenience.

CLOSE DIRECTION CURRENT SENSE ADJUSTMENT

When the gate operator leaves the factory, it has been preset for a relatively light gate function and will require additional

adjustment. Begin by starting the gate going closed. If the operator stops and reverses, turn the close direction potentiometer

(see page 9) one turn higher, press the STOP button, and try again. Repeat this process until the gate no longer causes false

tripping of the current sensor. Note that each time the gate operator reverses, the STOP button must be pressed. Next, turn the

close direction potentiometer lower slowly while the operator is running the gate closed until the gate operator stops and

reverses again. From this point, turn the close direction potentiometer higher by 1 1/2 turns for all 115 Volt AC and 24 Volt DC

operators, and by 3/4 of a turn higher for all 230 Volt AC operators.

OPEN DIRECTION CURRENT SENSE ADJUSTMENT

Repeat the same process with the open direction potentiometer while running the gate in the open direction. Once this is done,

run the gate through several complete cycles and make sure the gate does not false trip in either direction.

This adjustable potentiometer sets the maximum length of time the motor will run before shutting down. It should be configured

for the time it takes to run the gate fully open or closed, plus an additional 15 seconds. See page 9 for details.

This adjustable potentiometer sets the length of time which elapses before the gate operator automatically closes the gate, from

the fully open position, provided no open, reversing, or obstruction signals are present. This feature can be turned on or off via dip

switch selection. See page 9 for details. Do not use the auto close timer without an appropriate reversing device

installed!

A three-wire shielded conductor cable is required to connect master and slave operators. You must use Belden 8760 Twisted

Pair Shielded Cable (or equivalent) only – OSCO part number 2500-1982, per foot). See page 9 for details of this connection, as

well as dip switch selection.

must run power to both the master and slave operators.
