gate cycling troubleshooting

Gate Symptom
Gate moves slowly.
Gate beeps when
opening and closing.
Gate does NOT open.
Gate does NOT close.
Gate stops premature-
ly and beeps, moves
in opposite direction.
Gate will stop before
reaching desired limit
setting.
Gate stops abruptly
while in motion.
Gate re-opens while
closing.
Gate does not learn
new limit positions.
Unable to learn limits.
Gate NOT moving
after learning limits.

• Check if GATE SPEED rotary dial is set to MAX position (LED on).
• Gate may be too heavy for operator (check manual for maximum gate weight for your model operator).
• Check if "BATTERY IN USE" LED is ON. If so, gate is on Battery back-up mode and battery is running low.
• Gate hinges may be too tight.
• Operator may be in battery back up mode. check if "Mode A" switches are set correctly.
• Check if "Gate in Motion" Alarm feature is ON ("Mode A" switch 2 is set correctly).
• Check if Power LEDs are ON on both DSP board and Toroid box.
• Check if GATE "PULL open / PUSH open" switch is set properly.
• Check if GATE DISABLE LED is ON. If so, check if GATE DISABLE input is active.
• Check if "OPEN ONLY 10K/NC" LED or "OPEN/CLS" LED is ON or BLINKING. If so, check entrapment sensor wiring.
• Check if "BATTERY IN USE" LED is ON. IF so, battery may be too low and gate is kept closed (BATTERY BACK-UP MODE
switch set to "Leave Closed").
• Check if Power LEDs are ON on both DSP board and Toroid box.
• Check if "PHOTO CLS" LED is ON. If so, check entrapment sensor wiring and alignment.
• Check if any loops are active, check SAFETY LOOP, CENTER LOOP or EXIT LOOP LED is ON.
• Check if any open command inputs are active (check if LED is ON for: RADIO, FIRE DEPT, MAX OPEN, STRIKE,
KEYPAD/RDR. Check device connected to the input that LED light is turned ON.
• Check if GATE "PULL open / PUSH open" switch is set properly.
• If "OPEN ONLY 10K/NC" LED or "OPEN/CLS" LED is ON. If so, check entrapment sensor wiring.
• If "BATTERY IN USE" LED is ON and BATTERY BACK-UP MODE switch is set to "leave Open", then battery may be too
low and gate is kept OPEN.
• If "BATTERY IN USE" LED is ON and BATTERY BACK-UP MODE switch is set to "OPEN 1-TIME", then if AC power is
lost, gate will automatically open 1 time.
• If "CLOSE TIMER" is OFF, then gate will not close automatically. A close command (radio, close) is required to close gate.
• Loop detector is defective (CENTER, EXIT, or SAFETY). All 3 loop LEDs flashing indicates loop fault.
• Loop has a short or open. Measure loop resistance.
• Check if manual release on arm is released. If so, re-lock manual release.
• If "ERD" LED is ON, an obstruction (ERD event) is detected. If no apparent obstruction, select a less sensitive ERD
setting.
• If ANY UL sensor LED is ON, entrapment sensor is triggered.
• Gate Open and Close Limits have not been learned properly. Relearn limit positions by clearing limits first,
press STOP + CLOSE button together for 5 sec (until BEEP is heard), adjust limits and relearn NEW limits.
• Bad hinge - hinge pin offsets during motion causing abrupt gate movement.
• Operator placement is not proper or arm pivot point is not correct.
• Check if "OPEN/CLS" LED is ON. If so, check entrapment sensor wiring.
• Motor cable may be compromised. Unplug cable from "Motor Inputs" and ensure wires are not broken and are crimped
properly.
• Check if closing photocell is misaligned with reflector (check photocell on "PHOTO CLS", "OPEN/CLS" or "OPEN ONLY"
inputs.
• Use jog OPEN/CLOSE buttons to learn new positions instead of using OPEN or CLOSE buttons.
• Check label to see that OPEN/CLOSE limit wiring connections are correct.
• Ensure to go into learn mode: Hold STOP + CLOSE buttons until BEEP is heard, relearn limits by using OPEN and CLOSE
buttons.
• Ensure manual release is re-engaged.
