ProblemsCause/Solutions
Maintenance:• On all gates weighing 250 lb. or more, routinely grease the ball bearing rollers at least 4 times a year; grease more frequently if the gates are near a coastal area.
• Keep a few mothballs in the control box to discourage insects from entering it and damaging the control board.
• Have your gate operator tested monthly and serviced regularly by an experienced technician. The gate MUST stop and reverse on contact with an obstruction or when an object activates the non-contact sensors. If these functions are observed to operate improperly, discontinue use and have operator serviced immediately.
The operator has a 12 Vdc motor with mechanical limit switches.• To test the motor, put a voltmeter on DC and place the meter leads on the wire connections inside the plastic cover above the switches. The reading should be at least 11.5V when the system is active.
• To test the switc hes, put the meter on “ohms.” Place the leads on each of the wires on the switch. Y ou should have an open circuit. Click the switch and you should have .2 ohms. Do this for both switches.
• To test the cable, put the meter on ohms. At one end of the cable place the lead on the green wire, and on the other end of the cable place the lead on the green wire and the other wires. This should show a maximum of 1.0 ohms on the green wire and nothing on the other wires. Test each wire as you have above. If all have the proper readings, then this is not the problem.
• Note: Inspect the cable for any signs of any punctures because wires inside the PVC jacket can be shorted and the cable will still show proper ohms.
The control board: This is a micro processor board. The power that runs the gate is from the battery and recharged, through the board only, by a 18 volt 40 VA. (2.9 A) transformer.
There is one (1) green and one (1) red LED (light emitting diode) on the control board. They are for a quick reference only. All readings must be measured by a voltmeter!
The red light serves two purposes. The first is to aid in storing the personal transmitter code.
The second is to show the condition of the battery. If it is flashing, see the following section the battery. The normal state of this light is on, but dim.
If the red LED is flashing it means that the system may have reached low voltage lockout; the unit does not have enough voltage to operate the system. One of the following problems may exist:
• Broken or spliced wires from the transformer or solar panel to the control board.
• A transformer or solar panel that has no output voltage.
• Incorrect number of solar panels, or solar panels not properly hooked up.
The green light serves as a quick visual indication that the control board is receiving power from the transformer.
The transformer: Two things can cause failure: the first is shorting the leads during the installation, or letting the strands touch at the terminal on the control board. The second is a static charge (generally associated with a lightning storm or power outage); use of a surge protector will help.
Testing the battery: This is a 12 volt 7 Ah battery. The proper way to test this is to perform a load test. Place the voltmeter on D.C.; put the red probe on the (+) positive terminal and place the black probe on (-) negative terminal. Then activate the unit and watch the voltmeter. The drop should not be more than 1 volt.
Remote control range: This will vary at each installation, but generally varies from 50 ft. to 100 ft.
• Make sure that the receiver is located above metal fences.
• Moving the receiver even a few inches can change the range of operation.
• Move the receiver as far from the motor as possible to avoid the chance of electrical interference.
• Check or change the battery in the transmitter.

SymptomDiagnosis/Check
1. If the PWR OK light will not come on:A. Check the operator for inbound power.
B. The operator is in “learn” mode.
2. If the unit does not function:A. Check the operator for inbound power.
B. Make sure the ON/OFF switch is in the ON position.
C. Control board may be damaged; call the GTO Service Department.
3. If the control board lights are on but the unit will not operate:A. Press the reset button on the motor.
B. If you are using the transmitter to open the gate, jumper the CYCLE terminal. If the unit operates, the transmitter batteries may be discharged. Install fresh batteries in the transmitter. If problem persists, the receiver may be damaged. Call the GTO Service Department.
C. Disconnect the accessories from the control board and jumper the CYCLE terminal. If the unit operates; then reconnect each accessory and test each; one at a time.
4. If the gate starts: then stops or reverses:A. The transmitter button is being held too long.
B. If using a loop entry or exit, make sure the wires are connected to the correct terminal.
C. The gate operator may have been improperly installed.
D. The gate hinges are worn.
E. The gate is not level.
F. The obstruction level setting is too low.
5. If the gate opens but will not close:A. The auto-close timer (TYIR. OFF/ON DIP switch) is OFF.
B. An input (e.g., loop relay, push button, etc.) may be stuck.
C. Limit switch may be defective.
6. If the thermal overload button constantly trips (i.e., "pops out"):A. Motor current may be excessive; call the GTO Service Department.
B. Check wire connections.
C. The gate has cycled too many times for the ambient temperature.
