Standard Limit Ramp
The standard limit ramp is positioned
on the drive rail so it will make
contact with the limit switch and stop
approximately 2 inches (5 cm) from the
drive wheel.
Limit ramps are attached to the
underside of the drive rail when the
gate is fully open and fully closed.

Two truss head screws secure each limit ramp to the drive rail. The bolts
are spaced about 4 inches (10 cm) apart.
The limit switch must be set ⅜-inch (9 mm) from the base of the drive
rail. A screw on the limit switch allows for slight adjustments in height. If
XtremeDrive wheels are used, you will need to raise the drive rail
¼ to ½ inch (3 to 13 mm) along the gate uprights and the entire
drive rail path. The limit switch placement will need to be adjusted
accordingly.
All the limit ramps are the same length.
NOTE: For a 50VF-series SlideDriver, you will need to order four (4)
Slow Down Limit Ramp Kits.
Be sure to securely fasten all limit ramps to the underside of the
drive rail when installing a 50VF-series operator.
