FAULTPOSSIBLE CAUSEFIX

OPERATOR FAILS TO RUN 1) No stop control

2)Fault in the operator check the yellow diagnostic LED at the top right of the GL board next to the programming dip switches.

3)An accessory is active or malfunctioning check the red input status LEDs, D11-D31

4)Low or no high voltage power.

5)Low or no secondary voltage power

6)Improper TB11/TB12 wiring (Master/Second)

7)No LEDs illuminated on GL board

➤Check the green LED (D17) on GL board. If the green LED is off, check to make sure a stop control has been installed across terminals TB1-3 and TB1-5 of the Terminal Strip.

➤If the yellow LED blinks six times, there is a master/second unit communication failure. If operator is a single unit, make sure there is a jumper across terminals TB1-11 and TB1-12. If operator is in a dual gate configuration, make sure that the communication wiring between the two units is undamaged and complete.

➤If the yellow light is solid, the board needs to learn the motor. Follow the directions on page 14.

➤If any red LEDs are on, check the corresponding input. An installed accessory may be wired incorrectly or malfunctioning. Remove the accessory and test the operator.

➤If the open or interrupt loop LED is on, make sure factory plug-in loop detectors are working properly and appropriate loops are installed on the loop input terminals.

➤Measure the incoming voltage at the unit’s on/off switch. It should be within 5% of the operator’s rating when running. Make sure that the proper wire gauge was used for the distance between breaker and operator by consulting the wiring specifications section on page 12 of this manual.

➤Measure the voltage at terminals R1 and R2 in the operator. This voltage should be within 5% of 24VAC. If the high voltage power is good and the secondary voltage power is bad, check to make sure the circuit fuse is not blown and that the correct primary tap is used on the transformer. If fuse and tap are correct replace the transformer.

➤Stand-alone Operators: Make sure there is a jumper installed across TB11 and TB12.

➤Master/Second Operation: Make sure that the master/second wiring is installed correctly and is intact (not damaged).

➤If both primary and secondary power is good, check to make sure that the J2 connector is making good contact with the pins on the GL board. If all is good, replace GL board.

devices.

 

 

 

➤ Measure the incoming line voltage at the unit’s on/off switch. It should

 

 

 

 

be within 5% of the operator’s rating when running. Make sure that

 

 

 

 

 

 

 

the proper wire gauge was used for the distance between breaker and

 

 

 

 

operator by consulting the wiring specifications section on page 12 of

change in voltage. The voltage at the operator should be within 5% of

 

 

 

 

the operator’s rating when running.

 

 

 

 

➤ Check the number of amps currently being drawn from the panel.

 

 

 

 

Make sure that the total power being drawn does not exceed the

 

 

 

 

panel’s rating.

2) Problem in the motor

 

section on page 12 of this manual.

 

 

 

➤ Perform a visual inspection of the motor. Examine the motor’s labels

 

 

 

 

for any distortion or signs of overheating. Replace the motor if it is

 

 

 

 

humming, grinding or making excessive noise. Note: Repeated motor

 

 

3) Problem in the contactor

 

problems indicate poor primary power.

 

 

 

➤ Examine the contactor for sparking, smoke or burn marks. Remove

 

 

 

 

the wires from one side of the contactor, then measure the contact

 

 

4) Rail slippage

 

points for high resistance (above 1 ohm). Replace the contactor.

 

 

 

➤Observe the drive wheels as they move the gate. If the wheels slip on

 

 

 

 

the rail, tighten the compression springs until the rail no longer slips.
