34 - MAINTENANCE SCHEDULE
Alarm
Activate the (inherent) reverse system by blocking the gate with a solid object. The gate should
reverse momentarily then stop. Restart the gate and block again with a solid object. The gate
should reverse momentarily, then stop, and go into hard shutdown with an alarm
Backup System
If operator is equipped with DC backup system, check to be sure the system opens the gate
upon loss of AC power
Battery
If operator is equipped with DC backup system, check the batteries for any leakage or loose
connections. Batteries should be replaced every two years
Fire Dept
Check emergency vehicle access device for proper operation
Gate
Inspect for damage
Reverse System
Check that the gate reverses on contact with an object in both the opening and closing cycles
Loop(s)
Check vehicular reverse and shadow loops for proper operation
Release
Check manual release for proper operation
Complete
Overall Check: Complete check of gate and gate operating system
Mounting Hardware
Check screws and nuts
35 - TROUBLESHOOTING
SYMPTOM(S)
Operator will not Power On.
Power LED is OFF
Gate opens a short distance, then
stops and reverses
Gate opens but will not close
Battery backup system will not open
gate upon AC power outage
Hard Shutdown (2 back to back ob-
structions) LED blinking, Buzzer sounds
for 5 minutes
Gate opens by itself

POSSIBLE SOLUTION
Check that power to the circuit board is turned ON
Check terminal block wiring for loose or broken wires
If voltage measures OK, check the terminal block
Check the fuses (may be both AC and DC fuses in installation)
Check the external entrapment sensors on the gate controller
Adjust Force Settings
Check the input LEDs. Any ON will hold the gate open and indicates a problem with a keying device
Check the external entrapment devices. Any activated devices will hold the gate open and indicates a
possible problem with the device
Check the loop detectors. Any activated loop detectors can hold the gate open and indicates a possible
problem with the loop detector or ground loop
Check if backup system is set to open gate automatically or requires an input to open
Check the batteries for proper voltage. Replace if necessary
Clear any obstructions from the path of the gate. Press RESET to
clear (or hard reset button)
Check accessory inputs and clear then as necessary
