SECTION 3 - MAINTENANCE AND TROUBLESHOOTING
3.1 Maintenance
When servicing the gate operator, always check any secondary (external) reversing devices (loops, photo sensors, 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 the gate operator, be sure that the AC power switch is turned OFF AND battery plug is disconnected (Page 15).
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.

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 the batteries for any leakage or loose connections. Batteries
should be replaced every two years. P/N 1801-009. Two (2) required.
Check vehicular reverse and shadow loops for proper operation.
Check manual release for proper operation.
Complete check of gate and gate operating system.
Check emergency vehicle access device for proper operation.
Inspect for damage. Check gate hinges 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 if necessary.
Check secondary (external) reverse device(s) stop or reverse the gate
when activated.
3.2 Diagnostics Check
Have the following diagnostic tools available: VOM meter with minimum voltage memory or min-max range to check voltage
and continuity. Meg-ohm meter capable of checking up to 500 megohms of resistance to properly check ground loop integrity.
A malfunction can be isolated to one of the following:
• Gate Operator • Loop System • Keying Devices.
Disconnect all external inputs to the circuit board.
1. Check the input indicator LED’s. They should only come ON when a keying device (card reader, push button, etc.) is
activated. If any of the input LED’s are ON continuously, this will cause the gate operator to hold open. Disconnect the keying
devices one at a time until the LED goes OFF (see troubleshooting guide).
2. If the operator stops or holds open, check external secondary entrapment protection devices for any shorts or malfunction.
3. A malfunction in a loop or loop detector can cause the gate operator to hold open, or not detect a vehicle when it is present
over the loop. Pull the loop detector circuit boards from the loop ports on the operator circuit board. If the malfunction persists,
the problem is not with the loop system. For more information refer to the loop detector instruction sheet and the DoorKing
Loop and Loop Detector Information Manual. Continued on next page.
