If the Operator Does Not Work
If your gate operator does not function properly after it is installed, use this guide before calling the GTO Service
Department.
• On all gates weighing 250 lb. or more, routinely grease the ball bearing hinges at least 4 times a year; more
frequently if the gates are near a coastal area.
• Keeping a few mothballs in the control box will discourage insects from entering it and damaging the control
board.
• Clean the push-pull tube with a soft, dry cloth and apply silicone spray to it at least once per month.
Maintenance and Troubleshooting Guide
Check the Green LED on the Control Board:
IF THE LED IS OFF- This condition indicates a transformer power failure.
1. Test the transformer for voltage with a voltmeter. The acceptable range can be found in the
VOLTAGE LIMITS chart on the next page. If the transformer test shows no voltage, then
test the electrical outlet for voltage. If the outlet test shows voltage, then the transformer is dead
and must be replaced. Allow the new transformer 12 hours to charge the battery before using
the gate operator.
2. If the transformer test shows voltage, check the POWER IN terminal block on the control board
for voltage. If the terminal block shows no voltage, look for broken or spliced wires.
Check the Red STATUS LED on the Control Board:
IF THE LED IS ON–but the unit is not working
1. Check the battery in your transmitter and replace with a fresh one if needed.
2. Verify that the power cable is securely connected.
3. Replace the control board fuse if it is blown (15 ampere fuse only - DO NOT USE
A HIGHER RATED FUSE!).
IF THE LED IS OFF–
1. Make sure the ON / OFF switch at the bottom of the control box is set to ON.
2. Check all connections for looseness and corrosion.
IF THE LED IS FLASHING–
The system may be in a condition known as "low voltage lockout" (i.e., inadequate voltage supplied for the gate
operator to function.
1. Test (using a voltmeter) the voltage output of the transformer (18.0 to 22.0 Vac) or solar panel
(18.0 to 22.0 Vdc) at the control board power terminal block.
A. If the voltage is low or not reading, load test the battery at a electronics store and call your
dealer for a replacement battery if necessary.
B. If the voltage is low or not reading, test the transformer and electrical outlet. Replace the
transformer if necessary and let the battery recharge for 12 hours before using the gate
operator.
C. Check the control board for damage or corroded connections.
D. Make sure that telephone or solid core wire is not being used to connect the transformer to the
control board.
