7.1 Maintenance
SECTION 7 - MAINTENANCE AND TROUBLESHOOTING
Inspection and service of this gate operator by a qualified technician should be performed anytime a malfunction is observed or
suspected. High cycle usage may require more frequent service checks.
When servicing the gate operator, always check any secondary (external) reversing devices (loops, photocells, etc.) for proper operation. If
external reversing devices cannot be made operable, do not place this operator in service until the malfunction can be identified and corrected.
Always check the inherent reversing system when performing any maintenance. If the inherent reversing system cannot be made
operable, remove this operator from service until the cause of the malfunction is identified and corrected. Keeping this operator in
service when the inherent reversing system is malfunctioning creates a hazard for persons which can result in serious injury or death
should they become entrapped in the gate.
When servicing this gate operator, always turn power OFF!!
7.2 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 alarm 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 plugs are properly inserted into P2 and P8.
Constant alarm is heard: This indicates that the operator is in a hard shutdown condition. The alarm will continue to sound for
five minutes, and then will “chirp” once every five seconds. The operator-reset button must be pressed or power must be
removed and then reapplied to return the operator to normal operation.
Short “alarm chirp” 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 operator-reset button is pressed or until power is removed from the operator.
Operator runs for 1 second and stops, two short “alarm chirps” are heard: This indicates that there may be a fault with the
primary current sensor circuit. Check that the black current sensor wire has been passed through the hole in the primary
current sensor donut on the circuit board with the correct number of loops (1/2 HP motor - 2 loops, 1 HP motor - 1 loop).

Complete System
Activate the primary (inherent) reverse system by blocking the gate
with a solid object. When the gate reverses, block the gate in the
opposite direction prior to the limit being reached. The entrapment
alarm should activate. Press the reset button to silence the alarm.
Check for sagging. Tighten if necessary.
Check for alignment, tightness and wear.
Check vehicular exit and reverse loops for proper operation.
Check manual release for proper operation.
Pulleys Check for alignment. Check setscrews.
Complete check of gate and gate operating system.
Check emergency vehicle access device for proper operation.
Grease Wheels, guide rollers and limit nuts if necessary.
Inspect for damage. Check gate wheels. rollers and guides for wear
and grease if necessary.
Check that the gate reverses on contact with an object in both the
opening and closing cycles.
Adjust the reversing sensor and/or clutch if necessary.
Check secondary (external) reverse device(s) stop or reverse the gate
when activated.
