The All-O-Matic SW-350DC PRO is a 24V brushless DC swing gate operator, rated for gates up to 2,000 lb on the ½ HP model and 2,500 lb on the 1 HP, and up to 22 ft long. We diagnose and repair SW-350DC PRO operators and their ALL-BLDC PRO board, including ones we didn't install, starting with what the board's lights and event log say.

MODE light blinks once every two seconds: a problem with the motor sensor feedback.
MODE light blinks twice every two seconds: motor overload detected.
MODE light blinks three times every two seconds: the gate is jammed.
ALARM light on for 5 minutes: the operator shut down after the gate hit an obstruction twice before reaching fully closed.
AC/PWR ON light blinking about every half second: the main board fuse is blown.
LOW-BATTERY light on: the batteries are low, turned off or disconnected.
Event log MOTOR SF: motor sensor fault. Check the motor harness connections.
Event log MOTOR OL: motor overload. Check the gate hardware and the operator's capacity.
Event log FUSE BLOWN: motor fuse blown. Replace the fuse on the main board.
Event log EEPROM ERROR: processor error. Replace the board.
Event log MON-CLOSE FLT: fault on the monitored close input. Check the entrapment device alignment and function.
Most SW-350DC PRO faults are repairable. The board's lights and event log name the fault, and the board, batteries, limit switches, arm and fuse are separate parts. Replacement makes sense when the gearbox or motor has failed out of warranty late in the unit's life, or when the gate is beyond the operator's rating: 2,000 lb on the ½ HP model, 2,500 lb on the 1 HP, and 22 ft long.
For gates beyond that rating, All-O-Matic's SW-375DC PRO is rated to 5,000 lb and 30 ft. Older AC swing operators, including the discontinued SW-350 AC, retrofit to the DC PRO model, which has battery backup built in. We confirm the gate's weight and length and the mounting pad on site first.
The SW-350DC PRO is a current All-O-Matic product, from a manufacturer based in Van Nuys. We confirm the board, battery or limit part for your unit before we schedule the repair.

Veritas Access Solutions repairs All-O-Matic SW-350DC PRO operators across Los Angeles, Ventura and Kern counties, including operators another company installed. We read the board's lights and event log, diagnose on site and give you a written diagnosis before any work. Call 661-605-3266, or text a photo of the operator.
The built-in obstruction sensing (ERD) reverses the gate when it makes contact. If it hits an obstruction twice before reaching fully closed, the operator shuts down and the ALARM light stays on for 5 minutes. Find what the gate is hitting or binding on before resetting it.
Repair, in most cases. The board, batteries, limit switches, arm and fuse are separate parts, and many units are still under warranty. Replace it when the gearbox or motor has failed out of warranty late in its life, or the gate is beyond its rating of 2,000 to 2,500 lb and 22 ft.
It runs on two built-in 12V 7Ah batteries, rated for up to 250 cycles. Dip switches set what happens as the battery runs down: fail-safe opens the gate before the battery drains, fail-secure locks it closed, and auto-open opens it 45 seconds after power is lost.
Turn the operator power off, push the foot pedal down and move it to the left to lock it down, then push the gate open. The foot pedal has a kill switch, so the operator stays disabled while the pedal is down.
Yes. We check the board, limits, batteries, safety devices and primary-secondary pairing before quoting, whoever installed it.
It depends on the fault, whether the part is under warranty, the condition of the batteries and whether it is a single or double gate. We price after an on-site diagnosis rather than over the phone, and the estimate is free.
