Switch LED Diagnostics
Lift Out Switch: The Lift Out Switch stops in-
ward travel of the carriage/platform during Stow
function (activated by the housing-mounted Lift
Out Cam). Move cam in to increase inward
travel. Move cam out to decrease inward travel.
Diagnostic LED “LIFT OUT” will be illuminated
when the switch is not contacting the cam.
Full Out Switch: The Full Out Switch stops
outward travel of the carriage/platform during
Deploy (Up/Down) functions (activated by the
housing-mounted Full Out Cam). Move cam in
to decrease outward travel. Move cam out to
increase outward travel. Carriage rollers must
be inside housing a minimum 1.3 cm (1/2"). The
platform will not raise or lower until this switch
is activated. Diagnostic LED “FULL OUT” will
be illuminated when the switch is contacting the
cam.
