Alarm sounds for 5
minutes and then
chirps once every 5
seconds. Operator
will not run.
Symptom
Possible Solution(s)
•
Check the input LEDs. Any ON will hold the gate open and indicates a problem with a keying device.
•
Check the external 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 2 is ON.
Gate opens but will
not close.
Gate closes but will
not open.
Gate closes and then
re-opens.
Gate starts to close,
then reverses to
open.
•
Operator may be in a “soft shutdown.” Check input LEDs. If any are ON, momentarily disconnect,
then re-connect the wire going to the respective terminal. Operator should open.
•
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-1, switch 1. 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 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.
•
Check that the reverse sensitivity is properly adjusted.
•
Disconnect the gate from the operator and check that the gate operates freely without any binding.
•
Check the loop detector LEDs and input LEDs. Any that flash ON will cause the gate to reverse.
•
Check for proper loop wiring. A mis-wired loop detector will cause the gate to reverse.
•
Continue troubleshooting.
•
Check for any input or loop detector LEDs that are ON.
•
Check that the operator is running in the proper direction (see “gate closes but will not open” above).
•
Operator is in a “hard shutdown” condition. Alarm Reset button must be pressed to return operator
to normal operation. See pages 29 and 30 for “hard shutdown” information.
7.3 Built-in Diagnostics
This gate operator is designed with built-in diagnostics that will alert you to potential or existing problems that the microproces-
sor has detected. Specific fault conditions are checked and the operator will signal that a fault exist through the built-in alarm.
Constant tone is heard when power is applied:
This indicates that the limit switch wire harness is not connected to the circuit
board. In this condition, the operator will not run and the tone will continue until the fault is corrected. Check to be sure that
the limit switch plug is properly inserted into P3.
Constant tone is heard:
This indicates that the operator is in a hard shutdown condition. The tone will continue to sound for
five minutes, and then will beep once every five seconds. The alarm reset button must be pressed or power must be removed
and then reapplied to return the operator to normal operation.
Short tone is heard every five seconds:
This indicates that the operator has been in a hard shutdown condition in excess of five
minutes. This will continue until the alarm reset button is pressed or until power is removed from the operator.
Operator runs for 1 second and stops, two short tones are heard:
This indicates that there may be a fault with the current
sensor circuit. Check that the black current sensor wire has been passed through the hole in the current sensor donut with the
correct number of loops (DC motor - 2 loops).
