●
COMPLETE
●
Active the primary (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
Alarm
Backup System
If operator is equipped with option DC backup system, check to be sure the system opens the
gate upon loss of AC power
If operator is equipped with option DC backup system, check the batteries for any leakage or
loose connections. Batteries should be replaced every two years
Check emergency vehicle access device for proper operation
Inspect for damage
Check that the gate reverses on contact with an object in both the opening and closing cycles
Check vehicular reverse and shadow loops for proper operation
Check manual release for proper operation
Overall Check: Complete check of gate and gate operating system
Check screws and nuts

SYMPTOM(S)
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 UL/Edge input 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 secondary safety devices. Any activated safety devices will hold the gate open and indicates a
problem with the safety device
Check the loop detectors. Any activated safety devices can hold the gate open and indicates a 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)
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
Check accessory inputs and clear then as necessary
