Switch Adjustments
Adjustment Procedures
Full In:
When the Full In Switch is deactivated (de
-
pressed), inward travel of the lift during Stow function
is stopped. Power is removed from the pump motor
and In Solenoid.
The lift is fully stowed when the rubber bumpers are
compressed 1/8
"
to 3/16
"
and the pump shuts off.
1. Fully deploy lift and lower platform to the ground.
2. Loosen set screw and rotate front cam so that
screw is approximately at the 9:30 position.
3. Tighten set screw.
4. Stow lift.
5. If lift fully stows but pump continues to run, loosen
set screw and rotate front cam clockwise.
6. If the lift stops and is not fully stowed, loosen set
screw and rotate front cam counterclockwise.
7. Tighten set screw securely upon final adjustment.
Full Out:
The Full Out Switch prohibits outward travel
of the lift during Deploy function. Power is removed
from the pump motor and the Out Valve when this
switch is activated (pressed). The platform will not
raise or lower until this switch is activated (pressed).
1. Fully deploy the lift and lower platform to the
ground.
2. Loosen set screw and rotate the rear cam so the
set screw is on top (12:00 position).
3. Rotate cam counterclockwise until switch is acti-
vated (pressed).
4. Tighten set screw securely upon final adjustment.
Platform Unfold:
When the Platform Unfold Switch
is activated (pressed), it will prohibit the lift from stow-
ing anytime the platform is deployed (unfolded) during
the Stow function. Up / Down travel of platform is only
allowed when the switch is activated (pressed).
1. No adjustment available, bend microswitch lever if
needed.
Outer Barrier Occupied:
Power is removed from the
pump and Up Valve when the switch is deactivated
(depressed) while the Outer Barrier is occupied a
minimum of 3” above the ground. Power is stopped to
the pump and an audible and visual alarm will also be
activated during the Up function.
1. No adjustment available, bend microswitch lever if
needed.
Inner Roll Stop Occupied:
The switch interrupts
downward travel of the platform during the Down
function by removing power from the Down Valve. An
audible and visual alarm will also be activated at that
time.
The switch is deactivated (depressed) two places
during the lift cycle. First, when the Inner Roll Stop
is occupied in the range of 1
"
below floor level to the
point when the Inner Roll Stop is locked in the upright
position. This deactivation stops the downward travel
and triggers an alarm.
Second, when the Inner Roll Stop is in the full up and
locked position, the Inner Roll Stop Occupied Switch
is also deactivated (depressed). This does not stop
the platform or set off the alarm due to the deactivated
(depressed) Inner Roll Stop Deployed Switch.
1. No adjustment available.
Inner Roll Stop Deployed:
This switch is deactivated
(depressed) when the Inner Roll Stop mechanically
locks. The purpose of this switch is to override the In-
ner Roll Stop Occupied switch from stopping downward
travel whenever the inner roll stop is deployed and
locked.
1. See Floor Level for adjustment procedures.
Floor Level:
The Floor Level Switch has two functions.
Power is removed from the pump motor and the Up
Valve by the switch when activated (pressed) once the
lifting cylinders have reached full extension.
The switch also allows threshold sensing when the
switch is deactivated (depressed) denoting that the
platform is 1” below floor level.
Inner Roll Stop Deployed is automatically adjusted
when setting Floor Level.
1. Raise platform to floor level using the manual back
up pump. Stop raising platform once inboard end of
inner roll stop fully contacts vehicle floor.
2. Loosen the (4) screws attaching the microswitch
bracket to the Rear Outer Vertical Channel.
3. Slide microswitch bracket down until microswitch is
activated (pressed).
4. Tighten the (4) screws attaching the microswitch
bracket.
Stow Level:
The Stow Level Switch sets the height
at which the platform will be manually folded. It also
insures that the lift is compact enough to fit through the
lift bay opening during the Stow function. The switch
is activated (pressed) at and below Stow Level. Power
is removed from the Down Valve when this switch is
activated (pressed).
1. A good starting reference is to raise the platform
so that the Outer Vertical Channel top edge is 1/2
"
lower than top edge of the Inner Vertical Channel
(red Stow Level arrow decals should be aligned).
2. Loosen the (2) screws attaching the microswitch to
the Rear Inner Vertical Channel.
3. Rotate the bottom of the microswitch bracket inward
to lower Stow Level. To raise Stow Level, rotate the
bottom of the microswitch bracket outward.
4. Tighten the (2) screws attaching the microswitch
bracket.
