TROUBLESHOOTING SYMPTOM Gate closes, but will not open. Obstruction in gate's path does not cause gate to stop and reverse. Photoelectric sensor does not stop or reverse gate. Edge Sensor does not stop or reverse gate. Alarm sounds for 5 minutes or alarm sounds with a command. Alarm beeps three times with a command. On dual-gate system, incorrect gate opens first or closes first. Alarm beeps when running. Maglock not working correctly. Solenoid lock not working correctly. Switched (SW) Accessory power remaining on. Accessories connected to Switch (SW) Accessory power not working correctly, turning off, or resetting. POSSIBLE CAUSES a. Vehicle loop detector active b. Low battery with LOW BATT option set to CLOSE a. Force adjustment needed a. Incorrect photoelectric sensor wiring b. Defective photoelectric sensor a. Incorrect edge sensor wiring b. Defective edge sensor a. Double entrapment occurred (two obstructions within a single activation) a. Low battery a. Incorrect Bipart switch setting a. Expansion board setting b. Constant pressure to open or close is given a. Maglock wired incorrectly a. Solenoid wired incorrectly a. In limit setup mode a. Normal behavior SOLUTIONS 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. a. Refer to the Adjustment section to conduct the obstruction test and perform the proper force adjustment that is needed. 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. 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. a. Check for cause of entrapment (obstruction) detection and correct. Press the reset button to shut off alarm and reset the operator. 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 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). a. Pre-warning is set to "ON" b. Constant pressure to open or closed is given 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). 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). a. Learn the limits a. Move accessory to accessory power "ON" 36
