1. Insert limit buzzer. Place the bare end of the limit buzzer wire into the Limit1 OL1 terminal. Attach
the alligator clip from the other lead of the buzzer to the bare tip of the small black wire from the op-
erator arm.
2. Apply power to the circuit board
as previous seen in the instruc-
tions. The buzzer should be
sounding unless already on the
open limit switch.
3. Manually release the operator arm
and slowly move the gate from the
closed position to the open posi-
tion. If the buzzer stops and starts
again while moving to this position
make note of this for the next step.
Once the gate is in your desired
open position you are ready to ad-
just the limit switch.
4. If the buzzer had turned off and
back on while moving the gate
closed: Turn the FCC screw clock-
wise until the buzzer stops.
If the buzzer did not turn off and
back on while moving the gate
open: Turn the FCC screw counter
-clockwise until the buzzer stops.
5. Your limit is now set for the open
position and you can remove the
buzzer and put the black wire di-
rectly into the OL1 terminal.
