| • Check the PULSE LED on the circuit board. PULSE 1 should blink as the primary (or single) operator | |
| is running. PULSE 2 should blink as the secondary operator is running. If either PULSE LED is not | |
| blinking as the respective operator is running, check that the magnetic sensor is within 1/32 inch of | |
| the magnetic counter ring. | |
| • Replace the magnetic sensor. | |
| • Replace the circuit board. | |

| 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. | |

| • 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 | |
| above section if operator now opens but will not close. | |
| • 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 20 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. | |
