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 23.0 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 |
| Expansion board function not controlling gate. | a. Defective main board to expansionboard wiring b. Incorrect input wiring to expansion board c. Defective expansion board or defective main board | a. Check main board to expansion board wiring. If required, replace wire cable. b. Check wiring to all inputs on expansion board. c. Replace defective expansion board or defective main board |
| 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). |
| SYMPTOM | POSSIBLE CAUSES | SOLUTIONS |
| 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” |
| Accessories connected to Accessory power not working correctly, turning off, or resetting. | a. Accessory power protector active b. Defective control board | a. Disconnect all accessory powered devices and measure accessory power voltage (should be 23 – 30 Vdc). If voltage is correct, connect accessories one at a time, measuring accessory voltage after every new connection. b. Replace defective control board |
| Quick Close not working correctly. | a. Quick Close setting incorrect b. Interrupt loop detector c. Defective Expansion board | a. Check that Quick Close setting is ON b. Check operation of Interrupt Loop detector c. Replace defective Expansion board |
| Anti-Tailgating not working correctly. | a. Anti-Tail setting incorrect b. Interrupt loop detector c. Defective Expansion board | a. Check that Anti-Tail setting is ON b. Check operation of Interrupt Loop detector c. Replace defective Expansion board |
| AUX Relay not working correctly. | a. AUX Relay setting incorrect b. AUX Relay wiring incorrect c. Defective Expansion board | a. Check AUX Relay switches settings b. Check that wiring is connected to either N.O. and COM or to N.C. and COM. c. Set AUX Relay to another setting and test. Replace defective expansion board. |
| Solar operator not getting enough cycles per day. | a. Insufficient panel wattage b. Excessive accessory power draw c. Old batteries d. Solar panels are not getting enough sunlight | a.
