Certification Checklist Diagnostic Procedures
The following operations and conditions must be functionally verified in order for the lift to be FMVSS 403/404 compliant. If an operation does not function as described or a condition is not met, follow the referenced procedures to correct the problem or contact a Braun Corporation Product Support representative at 1-800-THE LIFT®.
•Vehicle movement is prevented unless the platform is fully stowed.
1.Verify lift stowed signal - pin 7 on the pump module has a +12 volt signal OR pin 9 has a ground signal (depends on interlock used).
2.Refer to the interlock installation instructions.
•Lift operation shall be inhibited unless the vehicle is stopped and vehicle movement is prevented.
1.Verify vehicle secure signal (pin 6) has a +12 volt signal.
2.Refer to the interlock installation instructions.
•The platform will not fold/stow when occupied.
-Refer to Platform Fold Pressure Adjustment procedures.
•The inner rollstop will not raise if occupied.
-Call Product Support
•The outer barrier will not raise if occupied.
-Refer to Outer Barrier Fold Pressure Adjustment
•Verify platform lighting when lift is deployed.
1.Replace bulb(s) in the light housing.
2.Check fuse (5 amp fuse on circuit board; F13)
•An audio warning (and visual warning for public lifts) will activate if the threshold area is occupied when the platform is a least 1" below floor level.
1.Remove the threshold warning plate
2.Verify the threshold strip switch connectors are connected (see illustration on Page 3)
3.Replace the threshold strip switch
4.Reinstall the threshold warning plate
•Platform movement is prohibited beyond the position where the inner rollstop is fully deployed.
-Call Product Support.
•Lift platform movement shall be interrupted unless the outer barrier is deployed.
-Call Product Support.

Platform Fold Pressure Adjustment
1.Position the platform at the floor level loading position.
2.Loosen the hex nut on the adjustment screw (do not remove hex nut).
3.Turn the adjustment screw counter clockwise until the platform does not fold when the Fold button is pressed.
4.Turn the adjustment screw clockwise in 1/4 turn increments and press the Fold button until the platform folds completely (Note: return the platform to floor level position after each attempt to fold the platform).
5.Turn the adjustment screw an additional 1/8 turn after the platform folds successfully.
6.Tighten the hex nut without moving the adjustment screw.
7.Verify the platform will not stow while occupied.

Note: Secure adjustment screw and tighten hex nut following adjustment.
Outer Barrier Fold Pressure Adjustment
1.Lower the platform to the ground level loading position.
2.Remove the pump cover.
3.Turn the adjustment screw (shown below) counter clockwise until the outer barrier does not raise when the Up button is pressed.
4.Turn the adjustment screw clockwise in 1/4 turn increments until the outer barrier raises and fully locks in position when the Up button is pressed. DO NOT turn the adjustment screw beyond this position.
5.Verify the outer barrier will not raise when occuppied.
6.Reattach the pump cover.

Platform Angle Adjustment
Adjusting the platform angle based on the relationship of the platform at ground level directly affects the angle of the platform when positioned at floor level.
Unfold the lift and visually examine the angle of the platform when positioned at floor level. Lower the platform fully and note the angle of the platform when it reaches ground level also. The outboard end of the platform (toe) must contact the ground first when the platform is lowered (all lift models).
Millennium “NL” Series:
The platform angle should be adjusted so there is a balance between the angle at both positions (equal amount of angle). Angle A should equal angle B as shown in Figure C.
Century “NCL” Series:
Vista “NVL” Series:
The platform angle must be adjusted so the outboard end of the platform (toe) is angled down slightly when positioned at floor level. See Figure D. The outboard end of the platform must contact the ground first to ensure the spring-loaded outer barrier unfolds fully.
Adjustment Procedures: Adjustment Allen screws are provided on each side of the lift platform for adjusting the platform angle. Details and photos are provided on the opposite page.
Base Plate Wedges: Installations where base plate wedges are used require more platform angle adjustment than normal.
Platform Stop Blocks: When adjusting platform angle, ensure both stop blocks are making full contact with the vertical arms (details on opposite page).
Floor Level Adjustment: Following platform angle adjustment, set floor level positioning as detailed in
Platform Floor Level Adjustment
(details on page 8).

Platform Floor Level Adjustment
Before setting floor level position:
•Adjust platform angle as detailed on page 6.
•Ensure both stop blocks are making full contact with vertical arms (details on page 7).
Floor Level Adjustment:
1.Position platform at desired floor level position (passenger loading/unloading height).
Position platform such that:
a.the inner roll stop is laying flat on the threshold plate
b.platforrm has not begun to fold
Note: Use hand pump to position platform at proper posi-
Diagnostics: Diagnostic codes have been established in event the lift platform floor position does not set (the lift does not sound three “beeps” - see Step 5 above). The control board located inside the pump hous-
tion if unable to stop platform when powering lift.
2.Turn Lift Power switch Off.
3.Press Floor Position Set button (located between pump housing and lift tower).
4.While pressing the Floor Position Set button, turn the Lift Power switch On.
5.Continue pressing the Floor Position Set button until the lift sounds three “beeps.”
6.Release the Floor Position Set button.
7.Cycle lift to verify that platform stops at the set floor level position. Note: If platform does not stop at
