SYMPTOM POSSIBLE CAUSES SOLUTIONS
Gate closes, but
will not open.
a. Vehicle loop detector active
b. Low battery with LOW BATT option set to CLOSE
a. Check all vehicle detector inputs for an active detector
b. Check if AC power is available. If no AC power, then running on
batteries and battery voltage must be 11.5 Vdc or higher. Charge
batteries by AC or solar power or replace batteries.
Obstruction in
gate's path does
not cause gate to
stop and reverse.
a. Force adjustment needed a. Refer to the Adjustment section to conduct the obstruction test and
perform the proper force adjustment that is needed.
Photoelectric
sensor does not
stop or reverse
gate.
a. Incorrect photoelectric sensor wiring
b. Defective photoelectric sensor
a. Check photoelectric sensor wiring. Retest that obstructing
photoelectric sensor causes moving gate to stop, and may reverse
direction.
b. Replace defective photoelectric sensor. Retest that obstructing
photoelectric sensor causes moving gate to stop, and may reverse
direction.
Edge Sensor does
not stop or reverse
gate.
a. Incorrect edge sensor wiring
b. Defective edge sensor
a. Check edge sensor wiring. Retest that activating edge sensor
causes moving gate to stop and reverse direction.
b. Replace defective edge sensor. Retest that activating edge sensor
causes moving gate to stop and reverse direction.
Alarm sounds for 5
minutes or alarm
sounds with a
command.
a. Double entrapment occurred (two obstructions
within a single activation)
a. Check for cause of entrapment (obstruction) detection and correct.
Press the reset button to shut off alarm and reset the operator.
Alarm beeps three
times with a
command.
a. Low battery a. Check if AC power is available. If no AC power, then running on
batteries and battery voltage must be 11.5 Vdc or higher. Charge
batteries by AC or solar power or replace batteries
On dual-gate
system, incorrect
gate opens first or
closes first.
a. Incorrect Bipart switch setting a. Change setting of both operator’s Bipart switch settings. One
operator should have Bipart switch ON (operator that opens
second) and the other operator should have Bipart switch OFF
(operator that opens first).
Alarm beeps when
running.
a. Expansion board setting
b. Constant pressure to open or close is given
a. Pre-warning is set to "ON"
b. Constant pressure to open or closed is given
Maglock not
working correctly.
a. Maglock wired incorrectly a. Check that Maglock is wired to N.C. and COM terminals. Check
that Maglock has power (do not power maglock from control
board accessory power terminals). If shorting lock’s NO and COM
wires does not activate Maglock, then replace Maglock or Maglock
wiring (refer to Wiring Diagrams).
Solenoid lock not
working correctly.
a. Solenoid wired incorrectly a. Check that Solenoid is wired to N.O. and COM terminals. Check
that Solenoid has power (do not power solenoid from control
board accessory power terminals). If shorting lock’s NC and COM
wires does not activate Solenoid, then replace Solenoid lock or
Solenoid wiring (refer to Wiring Diagrams).
Switched (SW)
Accessory power
remaining on.
a. In limit setup mode a. Learn the limits
Accessories
connected to
Switch (SW)
Accessory power
not working
correctly, turning
off, or resetting.
a. Normal behavior a. Move accessory to accessory power "ON"
