Linear VS-GSLG Manuals & Support

The Linear VS-GSLG is a variable speed industrial slide gate operator. A variable frequency drive runs a three phase industrial motor with programmable speed up to 24 in per second and soft start and stop.

It comes in 1/2, 1 and 2 HP for gates up to 4,000 lb. Single phase models still run a three phase motor through the drive. It uses the integral APeX controller.

Identify your model

The model number is on the label inside the cover, for example VS-GSLG-121. The first digit after the dash is horsepower, the second is voltage and the third is phase.

Horsepower: 2 = 1/2 HP, 1 = 1 HP, 7 = 2 HP
Voltage: 1 = 115 VAC, 2 = 208/230 VAC, 4 = 460 VAC, 8 = 208 VAC
Phase: 1 = single phase, 3 = three phase

Have the model and serial number ready when you order boards or motors. Parts can differ between single and three phase units.

The control board on VS models is a VS version (2510-295-VS). Do not swap in a GSLG-A board.

Manuals and documents

Troubleshooting

The APeX display shows dashes at idle, St for stop, FC for full close, FO for full open and En for an entrapment lockout. Error codes show as En plus a number.

En 00: entrapment lockout

Two obstructions in a row locked the operator out and the beeper sounds.
Clear the obstruction and press STOP or the RESET button on the cover.

En 01 or En 02: max run timer

The gate ran longer than the max run timer on open (En 01) or close (En 02).
Check for a broken chain or belt and a slipping sprocket or pulley. Check the timer setting.

Motor runs but the gate does not move

Mark the sprocket and torque limiter with a grease pen and watch for slip. Tighten the torque limiter if it slips.
Check for a broken chain or worn belts.
Check setscrews on pulleys and sprockets and look for loose keys.

Gate stops part way or stays open

Check the board for a lit safety, reverse, shadow, obstruction or stop input. Disconnect devices one at a time to find a bad one.
Check the loop detector lights. Unplug the detector and try the operator.
Make sure the gate moves freely before you raise the current sensing.

Other codes

En 03: COMM LINK failure between paired operators. Check the 3-wire shielded cable.
En 05 or En 14: battery voltage dropped after AC loss. Battery voltage must rise above 24 VDC.
En 07: low AC voltage at the controller. Restore normal AC power.

Variable frequency drive

If the drive shows a fault, note the code before you cycle power.
Speed and soft start and stop are set in the drive programming. Check those settings after a drive replacement.

Common questions

It needs at least two monitored safety devices, one for each direction of travel, before it will run. Approved devices include Miller Edge MGO20, MGR20 and MGS20 edges, the Miller Edge MIM-62 module, Omron E3K-R10K4-NR, Miller Edge RG-K-R and PG-K-R50 photo eyes, and EMX IRB-MON and IRB-RET photo eyes.

Two obstructions in a row lock the operator out and the beeper sounds. Clear the obstruction, then press STOP or the RESET button on the cover.

The max run timer ran out while opening (En 01) or closing (En 02). Look for a broken chain or belt or a slipping sprocket, and check the timer setting. Press STOP to clear it.

Connect the COMM LINK terminals A, B and C on both operators with 3-wire shielded cable (Belden 8760, Linear P/N 2500-1982). Set limits and entrapment settings on each operator alone first, then set both to dual gate.

Yes. On single phase models the variable frequency drive takes 208/230 VAC single phase in and runs the three phase motor.
