All-O-Matic OH-200 Manuals & Support

The All-O-Matic OH-200 is a commercial overhead operator for tilt-up gates, often used at underground parking and apartment garages. It moves gates up to 800 lb and 22 ft wide, 6.5 to 8 ft high.

The OH-200 DC has a brushless motor, a loop detector rack, soft start and stop and integrated battery backup. The OH-200 AC uses the simple All-O-Matic AC board.

Identify your model

The model and serial number are on the label inside the control box. DC PRO units have the ALL-BLDC PRO board with an LCD display. Earlier DC units have an LED-only board; use the earlier board manual below for those.

Track rails come in a standard 144 in length, and custom lengths are available.

Troubleshooting

The ALL-BLDC PRO control board has an LCD and input LEDs. Note which LEDs are on before you change any settings.

Gate does not run and the ALARM LED is on

The gate hit an obstruction twice before it reached full close, and the operator shut down.
Press the red RESET button next to the radio connector, then check that the gate is not bound up or jammed.
Retest the ERD (obstruction) sensitivity after you clear the cause.

Gate does not run

STOP LED on: the STOP input is open. It is a normally closed input, so check the device or the jumper.
MON_FAULT LED on: a monitored photo eye or edge is missing or faulty. The gate then runs only on constant pressure.

Opening or closing LED is on but the gate does not move

If the AC PWR LED blinks, replace the fuse at the bottom right of the board.
Check that the gate moves freely and the limits are set correctly.
Check that the motor harness is plugged in tight with no loose wires.

MODE LED blinks

1 blink every 2 seconds: motor sensor feedback problem. Check the motor harness.
2 blinks: motor overload.
3 blinks: the gate is jammed.

No power or slow gate

AC PWR_ON LED off: check main power, the AC power switch and the 10 A fuse on the EMI board. If the fuse blows again, check the bridge rectifier.
Gate runs slow: set the variable speed to 100%, then relearn the soft stop. Put the gate on the closed limit, press and release RESET, and run one full cycle without stopping.

AC models

Press RESET and count the MON-FAULT blinks to see which UL mode the AC board firmware is in.
A lit 24VDC overload light means a shorted accessory.

Common questions

UL 325 (2018) boards need monitored entrapment devices for the open and close directions. If a device is missing or faulty, the MON_FAULT LED lights and the gate runs only on constant pressure. Wire monitored photo eyes or edges, then press RESET.

Unlock the quick release on the drive arm and carriage, then move the gate by hand. Reconnect and lock it before you run the gate.

The operator shuts down after two obstructions before full close. Clear the obstruction, then press the RESET button next to the radio connector.
