Troubleshooting
If the door opener will not move.
Be sure you have gone through programming. Without programming no power is ever sent to the
operator arms.
Check wiring connections.
Check to be sure jumpers are in place between STOP, FSW OP, FSW CL to COM on terminal
block CN4.
If not using limit switches, be sure jumpers are in place between FCC1, FCA1, FCC2, FCA2 to
COMF on terminal block CN3.
Be sure the arms are locked out of manual operation.
Check all fuses, the fuses protect as follows but all are required for the arms to move:
F1: 10A – Power Supply, 24VAC
F2: 630 mA – Power supply to accessories and battery charger
F3: 630 mA – Flashing lamp output
F4: 3.15A – Electric Lock Output
If the door opener move a few inches or feet and stops or reverses directions.
Check dip switches to the left of the LED display. It should be 1:OFF, 2:OFF, 3:ON, 4:On. If the
dip switches are wrong, you must turn all power off before changing the dipswitches and then
turn power back on for the settings to take effect.
Increase the force setting to the highest force. The force setting is the A parameter, move the A
parameter to 4. If the door moves fully after doing so you may then work your way down force
settings to the lowest force setting that the door still moves correctly under.
Check the setback. The setback of the operator is important to correct operation due to leverage
the arm will have on the door.
If using limit switches, check limit switch placement and wiring. You can tell if a limit switch has
been triggered by watching to see if one of the lights above FCC1, FCA1, FCC2, FCA2 go unlit.
Whichever limit light is unlit is engaged.
