All-O-Matic SL-150 Manuals & Support

The All-O-Matic SL-150 is a heavy-duty slide gate operator for commercial and industrial gates up to 60 ft. The DC PRO runs a 24 VDC brushless motor: 1/2 HP for 3,000 lb or 1 HP for 4,000 lb.

The SL-150 AC is 115 VAC, 1/2 HP for 1,500 lb or 1 HP for 2,500 lb. Both have a 30:1 gearbox with internal clutch, a foot pedal release and a loop detector rack.

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.

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.
FP_DISABLE LED on: the foot pedal release is down. Lift it to clear the kill switch.
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 the UL mode. The firmware must match the monitored devices wired.
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.

Press down the foot pedal release on the operator. The pedal also cuts power to the motor, so lift it before you run the gate again.

It uses two 12 V, 7 Ah batteries in the control box. Check battery voltage on the LCD, and replace both batteries together when they no longer hold a charge.

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

All-O-Matic offers the TK-1000 tandem kit to run two operators on one gate.
