6.3 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 (1/2 HP motor - 2 loops, 1 HP motor - 1 loop).
