SYMPTOM | POSSIBLE CAUSES | SOLUTION |
Operator fails to | No Stop Control. | Check the green LED (D17) on control board. If the green LED is off, |
run. |
| check to make sure a stop control has been installed across terminals |
|

|
|
| Fault in the operator. Check the yellow | If the yellow LED blinks six times there is a master/second unit |
| diagnostic LED at the top right of the | communication failure. If operator is a single unit make sure there is a |
| control board next to the programming | jumper across J4 pins 1 & 2. If operator is in a dual gate configuration |
| dip switches. | 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 24. |

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

|
| Improper J4 Connector Wiring | |
| (Master/Second). | the J4 connector. |
|
|
|
|
| Master/Second Operation: Make sure that the master/second wiring is |
|
| installed correctly and is intact (not damaged). |
|
|
|
| Low or no high voltage power. | 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 14 of |
|
| this manual. |
|
|
|
| Low or no low voltage power. | Measure the voltage at terminals R1 & R2 in the operator. This |
|
| voltage should be within 5% of 24 Vac. If the high voltage power is |
|
| good and the low voltage power is bad, check transformer wiring and |
|
| replace transformer. |
|
|
|
| No LEDs illuminated on the control | If both primary and secondary power is good, check to make sure that |
| board. | the J2 connector is making good contact with the pins on the board. If |
|
| all is good, replace the control board. |
|
|
|
The relays chatter | Low secondary (low voltage) power. | Measure the voltage at terminals R1 & R2 in the operator. This |
when the operator |
| voltage should be within 5% of 24 Vac. If the high voltage power is |
begins to move. |
| good and the low voltage power is bad, check to make sure the circuit |
|
| breaker is not tripped and that the correct primary tap is used on the |
|
| transformer. If breaker and tap are correct replace the transformer. |
|
|
|
The operator runs | Low primary (high voltage) power. | Measure the incoming line voltage at the unit’s on/off switch as well |
slow and/or trips |
| as the meter base or sub panel. Make sure there is not a major |
the internal |
| change in voltage. The voltage at the operator should be within 5% of |
overload. |
| 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. |
|
|
|
|
| Make sure that the proper wire gauge was used for the distance |
|
| between breaker and operator by consulting the wiring specifications |
|
| section on page 15 of this manual. |
|
|
|
| Problem in the motor. | Perform a visual inspection of the motor. Examine the motor’s labels |
|
| for any distortion or signs of over heating. Replace the motor if it is |
|
| humming, grinding or making excessive noise. NOTE: Repeated motor |
|
| problems indicate poor primary power. |
