Owner's Manual
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.
The LPX1700 is shipped from the factory with the potentiometers set at
the minimum force setting. Turn the potentiometer 1/8 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 on Page 18.
TIMER TO CLOSE SETTING
The Timer to Close is controlled by the setting of the “AUTO CLOSE
TIMER” potentiometer on the control board, see Figure 21. When the
pot is adjusted fully counter-clockwise the Timer-To-Close is disabled.
Turning the pot approximately 1/4 turn clockwise will enable the Timer
To Close function with a delay of approximately 2 seconds between the
gate reaching the full open position and automatically closing. To
increase the time delay continue to turn the pot in the clockwise
direction to a maximum delay of 60 seconds (one minute).
AUTO RE-CLOSE (TIMER-TO-CLOSE FUNCTION)
If the Timer To Close function is enabled (see above), this activates the
Auto Re-Close feature on the motor control board. When the auto-re-
close is activated, the gate will re-close after stopping and backing-off
from a non-contact sensor input if the close movement was initiated by
the Timer-To-Close function on the control board. The gate will
additionally re-close once if the sensor input was received from a
contact sensor. The gate WILL NOT re-close if the inherent overload
sensor was activated or on the second sensor input received from a
contact sensor in the same close cycle. In the Slave Mode the Timer To
Close is automatically disabled.
FINAL INSTALLATION CHECKLIST
(Before powering up the operator for the first time.)
1. Use a voltmeter to assure the service voltage to the
operator is appropriate per the operator nameplate
label. Connection to an improper High Voltage AC
service is the most common cause of board failure in
new installations and is NOT COVERED BY
WARRANTY!
2. No accessory equipment is installed in the control box.
3. Routing for all wiring from the field devices into the
operator has the wires well clear of the motor V-belt and
the limit switches.
4. The junction box cover is securely fastened.
