OPERATOR FAILS TO WORK:
A. The overload kicked out. The overload in the
VS-GSLG is inside the motor. If it opens, you must
wait until the motor cools, which automatically re-
sets the overload.
B. Main power disconnected at the master distribution
panel. Reconnect power.
C. The secondary fuse has blown. Replace the fuse.
D. Motor control may have sensed a fault. Refer to the
motor drive display for fault codes.
MOTOR OPERATES, BUT THE GATE DOES NOT
MOVE:
A. Check to see the clutch is engaged.
B. Make sure the clutch is adjusted properly. (Factory
clutch settings are very light.)
C. Be sure the main chain is not broken.
D. Check for broken or disconnected internal drive
chains.
E. Check for loose set screws on pulleys and sprock-
ets.
MOTOR LABORING:
A. Check the gate to be sure it is not bound up.
B. Check the drive chain for obstruction.
C. Check the brake to be sure it is releasing.
TROUBLESHOOTING
LIMIT SWITCH GETTING OUT OF TIME:
A. Tighten tension on the main chain to be sure it is not
jumping teeth on the drive sprocket.
B. To check chain jumping, you must mark the drive
sprocket and chain with a piece of chalk. Run the
operator. Then check marks to be sure they match.
GATE STOPPING PART WAY:
A. Check the clutch setting. Do not overtighten.
B. Check adjustment of the maximum run timer.
(see page 10)

GATE STAYING OPEN WITH AUTOMATIC SYSTEM:
A. If the vehicle detector “DETECT” light is on, check the
drive for unwanted metal, retune the detector, and
check surface and loop wires for damage.
B. Verify dip switch #1 is turned on.
C. Make sure the close limit switch isn’t held open.
