and reverses.

• Check that SW-1, switch 7 is set correctly.

 

• 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.

• 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 SW-1, switch 4 is ON.

 

• Check motor as described on previous page.

• 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 SW-2, switches 1 and/or 2. Go to

 

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.

• If a shadow loop is used, check for proper wiring. A mis-wired shadow loop detector will cause the

 

 

gate to reverse.

 

• 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
