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 19. 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 to
activate and turning it counterclockwise decreases the force required.
The LPX1000 is shipped from the factory with the potentiometers set 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.
See FINAL SETTING OF THE OBSTRUCTION DETECTION
OVERLOAD FORCE setting on Page 19.
SETTING THE LIMIT SWITCHES
Before turning on the main power, set the limit
switches which are located on top of the frame,
between the control box and the reducer gearbox.
See Figure 18. In a right-hand installation, the
switch nearest the control box is the open limit
switch. In a left-hand installation, the
switch closest to the gearbox is
the open limit switch.
Manually push the gate all the
way open. Press down on the
spring loaded detent plate and
rotate the open limit nut toward
the open limit switch contactor
until you hear the open limit
switch click. Rotate the limit
nut two more slots to give the
operator time to stop the gate
after the limit switch has been
activated. Release the detent
plate and make sure it drops
into the slots on both limit nuts.
Manually push the gate all the
way closed. Depress the detent
plate and rotate the close limit
nut clockwise until the close
limit switch clicks. Again
rotate the close limit nut two
more slots. Release the detent
plate and make sure both limit
nuts are firmly seated.
The limit switches are now roughly adjusted. If the gate should stop
short of fully opened or closed, or if it bangs against the end stops
during operation, the limit switches can be fine-tuned after the operator
is powered up. (See FINAL SETTING OF THE LIMIT SWITCHES, P.
19.).
