not close. |
| • | Check the secondary safety devices. Any activated will hold the gate open and indicates a problem | |
|
|
|
| with the safety device. |
|
|
| • Check the loop detectors. Any activated can hold the gate open and indicates a problem with the | |
|
|
|
| loop detector or ground loop. |
|
|
| • Operator may be in a “soft shutdown.” Activate any keying device to determine if operator returns | |
|
|
|
| to normal operation. |
|
|
| • If automatic close is desired, be sure | |
|
|
| • Check motor as described on previous page. | |

|
| then | |
|
|
| • Check to be sure that the operator is running in the proper direction. Turn power OFF, and then back | |
|
|
|
| ON. Activate a keying device. Operator should run in the open direction. If operator runs in the |
|
|
|
| close direction, turn power OFF and change direction switch |

|
|
| • Be sure that the respective LED on the control board lights when the keying device connected to the | |
|
|
|
| respective terminal is activated. If LED does not light, momentarily place a jumper wire from |
|
|
|
| terminal 1 to the input terminal being checked. If LED lights and gate opens, problem is with the |
|
|
|
| keying device. If LED does not light, replace control board. |
