Troubleshooting Guide

If your gate opener does not function properly after it is installed, use this guide before calling the GTO/ PRO Service Department.

Audible Alarm Indications

Symptom

1)Gives one short beep and no operations when you press the remote.

2)Gives a three second tone, 1 second of silence, and then another three second tone repeatedly.

3)Gives a constant tone.

Diagnosis

1)There is a power problem with the Mighty Mule 500/502, PRO-SW2500/2502, PRO-SW3000/3200 and PRO- SW4000/4200.

-The battery could have a dead cell in it.

-The battery could be low. Disconnect the transformer or solar panel and check the battery voltage. If the battery is fully charged, the voltage should be between 12.5 vdc to 13.5 vdc. Any voltage reading below 12vdc is low.

-The battery could be dead or disconnected at battery or board. The transformer or solar panel is powering the board with the charge voltage. Disconnect the transformer or solar panel to see if the board still powers up.

-The fuse is blown. Replace the fuse.

2)On the Mighty Mule 500/502, PRO-SW2500/2502, PRO-SW3000/3200 and PRO-SW4000/4200, the board is giving a limit switch error. Check the connections on the power cable. If this does not work, check the terminal voltages on the circuit board that is supplied to the limit switch. The voltage across the orange and green and the brown and green should be 5 vdc without the arm connected. If the board is good, the arm will need repair.

3)Mighty Mule 500/502, PRO-SW2500/2502, PRO-SW3000/3200 and PRO-SW4000/4200

-The battery could be very low at about 10 vdc. Flip the power switch off and back on to see if it will clear the alarm. If the alarm is not cleared, check to make sure that there is power at the outlet. There could be a tripped breaker or GFI. The transformer could be unplugged. The transformer could be blown. If there is no charge power from the transformer, the green light will be off.

-The board has sensed an obstruction two times in a row. If the alarm clears by switching the power off and on, the board is sensing an obstruction.

o Something on or about the gate is causing the arm to push too hard to open or close the gate. Look for something in the path of the gate or something unlevel, out of plumb, or that is binding or pinching.

o This can be due to a low battery when the unit is charged with a solar panel. Test the charging circuit and the solar panel in direct sunlight.

o If the alarm will clear by switching the power off and on, the board is sensing an obstruction. Disconnect the arm from the gate. If it is still obstructing, increase the Stall Force. Max it out if you have to. However, do not leave the Stall Force at this setting when connected to the gate. If the arm is in the middle of its cycle, it extends a couple of inches, retracts a couple of inches, and the tube does not hit the limit switch when retracted, the rev counter in the arm is bad.
