Owner's Manual

engages the leaf on the open limit switch when approached from the
center of the threads on the limit nut threaded shaft. Listen carefully for
the "snap action" of the limit switch. It may be necessary to try this
operation several times until the "click" of the limit switch is clearly
identified. Once the exact position of the click is noted, rotate the limit
nut about two or three slots on the limit nut (each slot on the limit nut
equals approximately 1" of gate travel) more in the direction to the back
of the operator away from the gate. This will give the operator time to
stop the gate after the limit switch has been activated and prevent
banging of the gate on its mechanical stop.
Now, manually push the gate to the desired closed position. The closed
limit switch and limit nut will be the closest to the front of the operator.
Repeat the limit nut adjustment described previously. In this case, the
limit nut will be rotated towards the front of the operator. Again, after
carefully noting the position of the click on the engagement of the limit
switch, rotate the limit nut two or three slots on the nut toward the front
of the operator toward the gate.
When the setting of the limit nuts has been completed, manually move
the gate to the center of its travel.
The final setting of the limit nuts will be accomplished after the
operator has been powered up.
SETTING THE LIMIT SWITCHES FOR RIGHT-HAND
OPERATION
The wiring must be configured for right hand operation as described on
Page 15. Follow the same procedure as listed above, EXCEPT NOTE
that the Open and Close limit switches are REVERSED, see Figure
19a.
SETTING THE OBSTRUCTION DETECTION
OVERLOAD FORCE
The operator is equipped with an obstruction detection circuit which
will detect MOST obstructions in the gate's path. See Figure 20. The
overload force can be independently adjusted for OPEN and CLOSE
with the potentiometers on the controller board labeled, "OVERLOAD
FORCE". Turning a potentiometer clockwise increases the force
required to activate and turning it counterclockwise decreases the force
required to activate the overload device.
The GSX1000 is shipped from the factory with the potentiometers at
the minimum force setting. Turn the potentiometer 1/4 turn clockwise
to prevent the overload circuit from tripping due to the gate's inherent
friction.
