TROUBLESHOOTING CHART
OPERATOR DOES NOT
RESPOND TO
COMMAND.
• Battery not connected. At least one charged battery must be connected for the operator remote control to operate. Verify battery
fuse is intact. Check battery connections and battery voltage to be above 11.5Vdc. Replace batteries if necessary.
• STOP button connection loose or disconnected. Press the RESET button and verify that the STOP LED lights up and then turns off
after 10 seconds. Verify the wire connects between the STOP and CTRL PWR terminals.
• Radio module not plugged in. Verify the green Radio module (located next to the coaxial connector) is properly mated with both
4-pin connectors.
GATE STOPS
AND REVERSES
IMMEDIATELY AFTER
IT STARTS MOVING.
• Obstruction sensed. Check safety devices and gate for obstructions.
• A fault has occurred. Check Diagnostic LED for possible error codes.
• Force set too low. Adjust FORCE setting until gate completes a full open/close cycle without reversing. The force setting may need to
be adjusted in cold weather, as the gate will not move freely.
• Loops are reversed. Make sure that the Safety loop and Shadow loop are connected properly. The gate may trigger the Shadow
loop as it moves, so it must be connected to the correct input.
• Low or defective battery. At least one charged battery must be connected for the units to operate. Verify battery fuse is intact.
Check battery connections and battery voltage to be above 11.5Vdc. Replace battery if necessary.
GATE OPENS BUT
DOES NOT CLOSE.
• An open input is continuously activated. Check the open loop or vehicle probe to make sure they are clear of objects. Verify
connections and operation for these devices.
• Low battery. Measure the voltage across the battery. Voltage should be above 11.5Vdc. Replace battery if necessary.
• (Optional Accessory) Entry system output is connected to the OPEN input, and is “stuck” opening. Verify entry system connections
and operations.
• Obstruction blocking close photoelectric sensors, shadow loop, or safety loop. Check photoelectric sensors for alignment and verify
all connections and operation for safety devices.
• (Optional Accessory) Close safety edge is damaged or on an obstruction. Verify operation and connection of close edge.
• Verify that the Timer-to-Close is ON and adjusted to desired delay.
• Gate opened by a force obstruction reversal. Check the Diagnostic LED and clear gate path of any obstructions.
• The Interrupt loop or Shadow loop is obstructed (optional accessories).
• Obstructed close photoelectric sensor or edge (optional accessory). Check connections and operations of safety devices.
• Low battery. Measure the voltage across the battery. Voltage should be above 11.5Vdc. Replace battery if necessary. GATE DOES NOT CLOSE
AUTOMATICALLY WITH
TIMER TO CLOSE
ENABLED.
GATE 2 CLOSES
BEFORE GATE
1.
ALARM CONSTANTLY
SOUNDS 5 MINUTES.
SOUNDS WHENEVER A
COMMAND IS ISSUED.
ALARM IS BEEPING
3 TIMES ON A
COMMAND GATE
RUNS TOO SLOW.
• An open input is continuously activated. Check the open loop or vehicle probe to make sure they are clear of objects. Verify
connections and operation for these devices.
• (Optional Accessory) Entry system output is connected to the OPEN input, and is “stuck” opening. Verify entry system connections
and operation.
• Operator in Party mode after RESET button pressed while at the OPEN limit. Use a remote or the SINGLE BUTTON to close the gate
and reopen it. Verify that the TIMER RUNNING LED is flashing.
• Double entrapment occurred. Two successive obstructions were encountered while moving the gate. Press the reset button and
ensure that the gate path is clear of all obstructions. Check the FORCE setting to make sure it is properly set.
• Low battery. Measure the voltage across the battery. Voltage should be above 11.5Vdc. Replace battery if necessary.
• Open and Close Limits are set too close together. If the Open and Close Limits are set within the ramp down distance of each other,
the gate will run at slow speed all the time.
• The gate is starting within the ramp down distance from the Open or Close Limit. Gate will run slow to limits if motion is started
within the ramp-down distance from the limit.
• Lock/Bipart Delay not set. Slide the Lock/Bipart Delay switch to ON. Verify that Gate 1 starts moving first on open and last on
close.
• Gate is excessively heavy. Verify that the gate is within the ratings for this product. Disconnect the operator(s) and verify that both
gate(s) operate easily. If the gate(s) are harder to move in one direction verses the other, the gate must be adjusted.
• Gate is unbalanced. Disconnect the operator(s) and verify that gate(s) operate easily in both directions. If the gate(s) are harder to
move in one direction verses the other, the gate must be adjusted.
• Bad motor connection. Check the motor wires and connections for possible loose or corroded terminals.
ALARM BEEPS
WHEN RUNNING.
• Low battery. Measure the voltage across the battery. Voltage should be above 11.5Vdc. Replace battery if necessary.
