Adjustment Procedures
Lift Out Switch:  The Lift Out Switch stops inward 
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.  
Full Out Switch:  The Full Out Switch stops out-
ward 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 1/2".  The platform will not raise or lower 
until this switch is activated.  
Floor Level Switch:  See page 6 for procedures.
Stow Switch:  The Stow Switch controls the height 
of the carriage/platform before it moves inward dur-
ing the Stow function (activated by the torque tube-
mounted Stow Cam).  Rotate the cam in to decrease 
platform height.  Rotate the cam out to increase plat-
form height.  Adjust cam so lifting arms are aligned.  
View the platform position in the housing.
Barrier Down Switch:  This platform-mounted 
switch prohibits the platform from raising unless the 
outer barrier is in the full up position.  The Up func-
tion is prohibited if the outer barrier detent pin is not 
fully engaged also.
Drive Chain Adjustment
In event the drive chain sags 1/2" or more, adjust 
tension as detailed.  Tighten to eliminate visible sag 
but do not overtighten.
1.  Remove bottom pan.
2.  Pull the manual release cable and lock. 
3.  Remove adjustment bolt (tensioner) access 
cover.  
4.  Loosen inside jam nut.  Secure tensioner and 
tighten outside jam nut. Tighten to eliminate vis-
ible chain sag but do not overtighten.
5.  Lock jam nuts together making sure the ten-
sioner roller is horizontal.  Release and push the 
manual cable in fully.  Ensure platform is locked 
by moving the platform in and out until chain 
release assembly engages chain.
Carriage Ride Height Adjustment
The carriage horizontal arms move (roll) in and out 
of the housing tracks on roller bearings.  Follow-
ing installation or extensive lift operation, clearance 
between horizontal arms and tracks may diminish.  
The eccentric shaft mounting plate allows height 
adjustment.  
   
Remove eccentric plate mounting screw.  Using 
screwdriver or small rod, rotate the shaft clockwise to 
increase carriage height.  Rotate the shaft coun-
terclockwise to decrease carriage height.  Reinstall 
mounting screw in nearest retainer hole.  Adjust 
left and right side eccentric shafts (screw positions 
may vary from side to side).  Adjust height such that 
horizontal arms do not contact top or bottom of tracks 
(align center). 
Calibration Procedures
Platform Sense Calibration
1. Place 20 lbs. in the center of the platform.
2. Press UP button on the hand-held pendant to raise 
the platform a minimum of 3" above stow level. 
3. Press and hold 50# CAL button on control board.  
While pressing the 50# CAL button, press and 
hold the STOW button on the hand-held pendant.  
The platform will lower to stow level, raise slightly, 
lower to stow level, and begin inward travel.  
Release the 50# CAL button when the platform 
begins moving inward.  The platform sensing is 
now calibrated. 
4.  After calibration, the LCD screen should read “PF 
OCCUPIED” when 50 lbs., or more, are present 
on the platform.  If 50 lbs. does not activate the 
“platform occupied” signal readout, recalibrate with 
less weight to lower the “occupied” setting or more 
weight to increase the “occupied” setting.  
Ground Sense Calibration
1. Press hand-held pendant DOWN switch to lower 
platform fully to ground level.
2. While continuing to press the pendant DOWN 
switch, press and then release the control board 
O_BAR/GROUND LVL  button.
3. Release the pendant DOWN switch.  Ground 
Level sensing is now calibrated.
4.  After calibration, the outboard roll stop should 
not unfold (down) until the platform is fully on the 
ground.
Outer Barrier Occupied Calibration
1. Press hand-held pendant DOWN switch to lower 
platform fully to ground level.
2. Once outer barrier is fully unfolded (ramp position), 
release the pendant DOWN switch.
3. Press and hold the control board O_BAR/
GROUND LVL  button.  While holding O_BAR/
GROUND LVL button, press hand-held pendant 
UP switch to raise the outer barrier.  Be sure to 
release O_BAR/GROUND LVL button when outer 
barrier reaches approximately half full up (vertical) 
position. 
4. After calibration, the LCD screen should read 
“OUT-BAR OCCUPIED” whenever there is weight 
present on the outer barrier.
