Terminology
Introduction
The RA200 provides fully automatic operation of all ramp
functions. Basic ramp operation
procedures are identical for all
RA200 models. The operating
instructions contained in this manual address the operator input
switches and the corresponding
ramp functions. Instructions are
provided for manual operation of
the ramp in the event of power or
equipment failure.
Terminology: Become familiar
with the terminology that will be
used throughout this manual.
Become familiar with the identification of RA200 components
and their functions. Contact your
ramp sales representative or call
The Braun Corporation at 1-800THE LIFT if any of this information is not fully understood.
Direction: The terms “left”,
“right”, “front” and “rear” will be
used throughout this manual to
indicate direction (as viewed from
the outside of the vehicle looking
directly at the ramp’s front cover).
Refer to the Ramp Terminology
Illustrations for clarification to
direction terms.
Ramp Components
Refer to the Ramp Terminology
Illustrations and discriptions on
pages 2 and 3.
Control Box (Electronic Controller): The remote mounted
control box provides the logic
to manage the inputs in order
to produce the desired outputs
in terms of ramp function and
performance. In general terms of
abilities and features, the control
box is commonly referred to as
the “controller.”
Ramp Cassette (Housing):
The ramp cassette is the metal
structure (casing) mounted under
the vehicle which contains and
protects the platform and carriage
assemblies. The cassette contains all ramp components except
the control box when the ramp is
in the stowed position.
Carriage Assembly: The carriage assembly consists of the
steel weldment that contains the
four track rollers, the main rotation
axle and the electric drive motors.
The carriage assembly powers the
platform assembly in and out of
the housing during operation.
Platform Assembly: The platform assembly consists of the flat
aluminum laminate upon which the
wheelchair travels, the sensitivity
edge, the supporting hinge, the
associated skid pads, and pressure mat.
Cable-activated Manual Release
System: A cable-activated man-
ual release system disengages or
“unlocks” the carriage assembly
drive chains to allow the platform
and carriage assemblies to be
manually moved out (extended) or
moved in (retracted), should it be
necessary. Complete details and
manual operating procedures are
provided on page 10 and 11.
Ramp Actions and Functions
Extend: Extend is the action of
the platform and carriage assembly moving out of the ramp cassette (housing).
Retract: Retract is the action of
the platform and carriage assembly moving into the ramp cassette.
Deploy: Deploy is the action of
the platform and carriage assembly extending and raising (elevating) to floor level when the DEPLOY (OUT) switch is activated.
Stow: Stow is the action of the
platform and carriage assembly
lowering to stow level, and fully
retracting when the STOW (IN)
switch is activated.
Stow Level: Stow level is the
height at which the platform and
carriage assembly extends and
retracts.
Floor Level: Floor level is the
height that the platform assembly
raises (elevates) to in order for
the wheelchair to enter or exit the
vehicle.
Obstruction Sensing: An obstruction sensing feature is standard with the RA200. The controller monitors the instantaneous
current of all the electric motors,
and calculates a ‘real time’ running average of the current. It
then compares programmed peak
(maximum vs. instantaneous) and
delta (instantaneous minus running average) limits to determine if
an obstruction has been encountered. The programmed limits for
the different models of the RA200
are selected while configuring the
controller during ramp installation procedures (see Installation
Instructions for detailed information).
Obstruction Force: The obstruction force is the maximum allowable force (pounds or Newtons)
the ramp exerts on a object during
a specific movement. There is a
different force for each of the four
movements (extend, retract, raise,
lower). This force is a direct result
of the obstruction sensing current
limits, usually specified by the
customer.
Note: Further details regarding
ramp control switches and the
corresponding ramp functions are
provided in the Ramp Operating
Instructions below and on page 8
and 9.

Operation
Pre-Operation Notes
Operation Procedure Review:
The RA200 operator should review all safety precautions and all
operation procedures appearing
in this manual prior to attempting
to operate ramp. Failure to do so
may result in serious bodily injury
and/or property damage.
Operate the ramp through all
functions to ensure the proper
use and operation of the ramp is
clearly understood. Be sure to
review the manual operation procedures, particularly the proper
re-engagement procedure of the
manual cable release system
(see page 10). Any questions or
concerns should be forwarded to
your Braun representative.
Do not operate the ramp if it is
suspected to be damaged, have
excessive wear, or any abnormal
condition. Discontinue use immediately and contact an authorized
Braun representative.
Preventative Maintenance:
Maintenance is necessary to
ensure safe and trouble-free
ramp operation. General preventative maintenance consisting of
inspecting, cleaning and lubricating procedures should be part
of a scheduled routine. Simple
inspections can detect potential ramp operational problems.
Adjustments can be made as
needed (details in Maintenance
and Adjustments section).
Regular preventative maintenance will reduce potential ramp
operation downtime and increase
the service life and reliability of
the ramp, as well as enhancing safety. Exposure to harsh
weather elements, environmental
conditions or heavy usage may
require more frequent mainte-
nance and lubricating procedures.
See the Maintenance and Adjustments section for more detailed
information.
Cold Climate Recommendations: The vehicle in which the
ramp has been installed should
be stored in a garage or other
sheltered place if possible, especially during inclement weather
conditions. When the ramp is not
in use, it should be in the stowed
position to prohibit rain, snow, ice,
dirt, mud, or other foreign materials from entering the ramp opening or building up on the platform
surface.
Ramp Operating Instructions
Ramp Operating Instructions
address the required controller
inputs and the corresponding
ramp functions. Instructions for
customer specific display panels
and interlock options will not be
addressed due to the boundless variations in application and
installation of the ramp. Manual
Operating Instructions are addressed in the event of power or
equipment failure.
Before Operating Ramp: Always park the vehicle on a level
area, away from vehicle traffic.
Place the vehicle transmission
in “Park” and engage the park or
emergency brake.
Customer Interlock: The ramp
controller requires a (+) 24V signal be supplied which interlocks
the ramp functions with a customer supplied vehicle signal. If
this interlock signal is not present,
the controller will not provide any
outputs necessary to operate the
ramp. If the interlock signal is lost
during ramp operation, the platform assembly will automatically
complete the ‘full stow’ sequence,
and the controller will not function any further until the interlock
signal is present once again.
Operator Input Switches: The
RA200 electronic controller provides fully automatic operation of
all ramp functions, which are protected by the obstruction sensing
feature. Ramp functions can be
performed from any position the
platform assembly happens to be
in at the time the operator input
switch is activated.
Two-Way Toggle Operation:
In two-way toggle mode, there
are separate switches for deploy
and stow functions. One of the
switches must be pressed and
held or locked into position (continuous input signal required) for
the RA200 to operate. The ramp
will move in the selected direction
until the switch is released (signal
interrupted), the unit reaches the
end of the travel, or a “halt condition” occurs (details follow).
Halt Conditions: Several conditions can cause a normal sequence to terminate (stop):
• Obstructions (details below)
• Customer Interlock signal lost
(see Customer Interlock)
• Manual Release System ‘unlocked’ signal present (see
Manual Operating Instructions:
Mechanical Method)
• Control Box Manual Input Switch
pressed (see Manual Operating
Instructions: Electrical Method)
• Weight sensed on platform
Obstructions: The controller
performs obstruction sensing (see
RA200 Terminology: Obstruction
Sensing) on all stow and deploy
movements of the ramp (in, out,
up, down), whether operated normally or with the manual override
switches. The selected obstruction response mode configured
Page 8
Page 11
Operation
in the controller during installation immediately stops movement when obstructed. Once an
obstruction has halted the ramp,
the controller automatically resets
and awaits operator input for
further operation.
Note: The ramp will sense an
obstruction and halt with any
substantial weight on the platform
(built-in safety feature). The ramp
will continue when the weight is
removed from platform.
Operation Functionality
The 100465-002 easy ramp control box incorporates a Microchip
PIC microcontroller that executes
a sequential program from a
built-in flash memory. This sec-
tion gives a brief overview of the
operational functionality that the
firmware provides in the operation
of the ramp.
“Close All Doors” Input: An
optional input, “Close All Doors,”
may be used to cause a stow
sequence. This input is also a
momentary pulse input. At the
completion of a stow cycle, the
control box will de-activate the
“Open Door” output. The door
should then automatically close.
Opening Door: The control box
opens the door using the “Open
Door” output. For the duration of
the ramp deployment and stow
cycle, the door shall never be allowed to close. At the completion
of a stow cycle, the control box
will de-activate the “Open Door”
output. The door may automatically close or close after the driver
signals the door to close.
If the door fails to open after an 8
second timeout period, the “Open
Door” output will be deactivated
and the ramp will not be deployed.
The leading edge ovstruction strip
would be wired with the pressure
mat and therefore behave similarly.
Ramp Alarm: Prior to any motion of the ramp, an alarm output
is activated for a few seconds.
The alarm output sounds for the
duration that the ramp platform is
not fully deployed or fully stowed.
This continuous output is used to
power an audible alarm and/or
lights. For the lights to flash, a
special harness (ER1320A) is
used with a built-in flashing unit.
One-Touch Operation: A momentary pulse input from an operate button will start an automated
deployment sequence. The user
does not have to continue to
press the operate button for the
ramp to complete its motion. In
a similar manner, the user need
only push the operate button once
again to start a stow sequence.
Ramp Enable: The ramp must
first be enabled by applying a momentary pulse signal to the ramp
enable input (momentary pushbutton switch). Once enabled,
the “Ramp Enabled” normally
open (N.O.) output is activated.
Then, the ramp may be operated
using the “Ramp Operate” button.
The ramp is automatically disabled when the platform becomes
fully stowed at the end of a cycle.
The ramp may also be disabled if
the enable push-button is pressed
again.
Obstruction Sensing: The
control box can sense if the ramp
platform is obstructed during
movement using a pressure mat
and over-current circuitry. If one
of these detection techniques occurs, the ramp is halted. If three
consecutive obstructions during
the deployment cycle occur, the
auto-stow feature described in
Section 3.10 will execute.
Pressure Mat Detection: The
top surface of the ramp platform
is covered with a weight or pressure sensitive mat. If a passenger is on top of the platform,
the ramp will not move when
activated. If the ramp is already
in motion and weight is applied to
the platform, the ramp will halt its
motion. Additionally, the platform
may be equipped with a pressure
sensitive edge strip that senses
obstructions at the leading edge.

Manual Operating Instructions
The RA200 has the capability of
being manually operated (mechanical or electrical methods). If
you experience power or equipment failure, refer to the stepby-step instructions to manually
operate the ramp. Always use extreme caution when operating the
ramp manually. Read all Manual
Operating Instructions carefully
and thoroughly prior to performing manual operating procedures.
Follow all Ramp Operation Safety
Precautions at all times.
Mechanical Method
Cable-Activated Manual Release System: A cable activated
manual release system disengages (unlocks) the carriage assembly drive chains to allow the
platform assembly to be manually
extended or retracted as required.
A T-handle is provided on the
release cable for activation of the
manual release system (details
follow).
After manually extending or
retracting the platform assembly,
it is extremely important that the
cable-activated manual release
is positively reengaged to secure
(lock) the platform assembly
before loading a passenger or
continuing vehicle use (details
provided). Failure to reengage
and secure the platform may
result in unintended ramp
movement, which may result
in serious bodily injury and/or
property damage.
injury. The unlocked signal may
also be used to supply a visual
display to the operator that the
ramp is unlocked and must be
secured prior to any additional
operation of the ramp or vehicle.
Note: The unlocked sensor
LED is not supplied (customer
installed).
Self-Locking Release Pin: A
self-locking release pin allows
the platform assembly to be
disconnected from the elevation
mechanism, allowing a raised
platform to be manually lowered
in the event of a power failure.
See Photo below. The release
pin should only be used when
the platform will not lower under
electric power, as stated in the
Electrical Method section (next).
To Manually Extend or Retract
Ramp:
1. Turn (loosen) the manual
release “T” handle 90°.
2. Pull the “T” handle fully outward (3" to 4").
3. Turn (tighten) the “T” handle
90° to secure handle in the
disengaged (unlocked) position.
Self-Locking Release Pin
4. Verify mechanism is disengaged (unlocked). View
customer installed sensor LED.
5. Carefully move the platform
in or out to desired location
using the platform Hand Hold.
Reengage Carriage Assembly
by Drive Chains:
1. Position the ramp platform
manually so that only 15 cm
is extended out of the cassette.
2. Turn (loosen) the manual
release “T” handle 90°.
3. Push the “T” handle fully
inward until handle contacts
shaft shoulder (3" to 4").
4. Grasp the platform Hand Hold
and move the platform slightly
outward until platform locks
into position (secured by
reengaging the carriage assembly with the drive chains).
Note: Do not push platform
inward to lock as it may then
create a binding condition in
the release mechanism and
will not release easily in the
future
Manual Release System Security Sensor: A proximity sensor
detects when the cable-activated
manual release system is disengaged (unlocked) and provides a
ground (-) "unlocked" signal to the
controller. The unlocked signal
disables all controller functions so
that the mechanism can be manually operated without the risk of

allow normal ramp operation).
The switches can also be used
in event of an electrical problem
remote from the ramp electrical
system (such as a problem with a
vehicle installed control switch or
interlock circuit).
Note: There must be power to
the ramp system (electronic controller) in order to use the manual
input (override) switches.
Each respective override switch
can be used to move the ramp
platform in the stated direction
(as labeled); OUT (extend), IN
(retract), UP (raise or elevate) or
DOWN (lower). The IN and OUT
switches use the control logic to
limit the travel to the maximums
as set by the respective sensor
pickups. Caution! The UP and
DOWN switches are not limited
to the sensor pickups, and thus
manual over travel can occur.
Over travel may result in damage
to ramp components or serious
bodily injury if not used with
extreme caution.
Electrical Method
Control Box Manual Input
(Override) Switches: Manual
input switches are located inside
the electronic control box. Do
not use manual input switches
to operate the ramp when load-
ing or unloading a passenger.
These momentary contact switches are provided as an override
for maintenance and service
purposes only. Manual input
switches should be activated by
qualified technicians only.
A service technician can use the
manual input (override) switches

so that the elevation motor stops once the
platform has gently touched against the
top cover lip (see Photo G on page 13 ), or
vehicle threshold if further from the center of
the vehicle. Incorrect setting of this pickup could result in a large gap between the
platform and the threshold (too low) or in the
ramp retracting into the stowed position due
to obstruction sensing (too high).

smooth transition of the ramp platform into the
cassette. Ramp skid pads, located on the back
corners of the ramp (see Photo J), reduce friction
at the point where the ramp corners contact the
top of the guide rail. See Photo K. Carefully observe the ramp skid pads when adjusting the stow
level sensor pick-up. Note: An incorrect setting
of the stow level could result in excessive wear,
premature failure, or the shearing off of the ramp
skid pads (pads are replaceable).

Maintenance, Lubrication & Adjustments
Floor Height: Variable height adjustments are
made by screwing the four threaded bar ramp
supports in/out to achieve the desired floor level
height. Once initially set during installation, this
height should not require altering. Two items to
note.
1. When increasing the height, the maximum
is achieved when the ramp toe contacts the
inside of the front cover (see Photo M). If the
maximum is surpassed, the front cover will
remain partially open when the ramp is in the
fully stowed position, thus allowing foreign
material and debris to enter the cassette.
2. When decreasing the height, the non-used
portion of the threaded studs must be cut off
to maintain proper clearance for main axle
rotation (see Photo N). Failure to do so may
result in the inability of the platform to lower
to stow level due to a binding condition of the
main axle, possibly causing damage to the
elevation motor.

Interior Maintenance and Lubrication
The following items can be accessed through the interior
of the ramp by removing either the top or bottom cover.
Bottom Cover: The snap-on bottom cover can be
removed for easy access. The bottom cover is easily
removed via two draw latches on each side (see Photo
P), along with four bolts across the front (see Photo O).
When replacing, make sure to install a new tie wrap on
the latches in order to secure the bottom cover. Inspect
the bottom cover seals and replace when necessary.
Top Cover: Only remove the top cover when deemed
absolutely necessary to obtain access to specific parts
not available via the bottom cover. Remove the ramp
mounting hardware and lower the ramp assembly in
order to remove the top cover. Replace the double sided
foam tape seal whenever the top cover is removed.
Cleaning and Lubrication: All interior parts
of the ramp, accessible via the top or bottom
cover, may be cleaned with high pressure
air only. Use a cleansing cloth to wipe away
debris deposits and large buildups.
Ensure guide rails are clean and free of all
debris. Carriage track rollers are sealed and
do not require lubrication.
Note: Ramp controller includes an Obstruction Sensing Feature. Debris build
up or obstructions (rocks, sand, dirt) in the
guide rails can result in the ramp stopping
or reversing direction during in-out functions
(if obstructed). Again, ensure the guide rails
are clean.

Chain System: The ramp utilizes a 3 chain system.
Two drive chains, left and right, provide the means
for the carriage to travel along. The third chain, in
the rear of the cassette, interlocks the left and right
drive chain to rotate in sequence (or equal time).
During normal operation, none of the 3 chains move.
However, during manual operation of the ramp, all 3
chains travel equal distances. To lubricate, a light oil
may be used on the chains, but should be limited to
reduce the possible buildup of debris.

Drive Chain Drive Chain
Inspection and Adjustment: Braun specifies a
drive chain tension that requires a force gauge and
metric tape measure for accurate setting, inspecting, or adjusting on all models of RA200 ramps.
Braun recommends the Wagner Force Dial gauge
model FDK 20 or FDN 100. These gauges can be
found at www.wagnerforce.com.
1. Remove the bottom cover of the ramp assembly.
2. Position the ramp in the fully deployed position.
3. Measuring from the back of the carriage the
distance L1 = 200mm (for all models), hook the
force gauge to the outside edge of the drive
chain (photo Y).
4. Pull the force gauge inward until the center of
the drive chain linkage measures approximately
85mm from the edge of the extruded housing (L2
in photo Y). The nominal chain tension (on the
force gauge) should read 5.5 kg ± 0.5 kg (55N ±
5N). Adjust the tension by tightening the respective locknuts as required. Note: Improper chain
tension may result in poor ramp performance,
difficult ramp operation or excessive wear/ pre-
mature failure of respective drive components.
5. Repeat steps 3-4 for the opposite drive chain,
again ensuring the tension force is within the
recommended range.
6. Proceed with the Carriage "Full Out" Alignment to
ensure proper chain tension and alignment.

Carriage “Full Out” Alignment: When the
carriage is deployed to the “Full Out” position, the front bar of the carriage should align
parallel with the union bar of the housing.
This alignment will help ensure that a fully
deployed and elevated platform will properly
align with the bus threshold. Properly maintaining this carriage alignment will also help
provide optimal performance during the in/out
movement of the carriage and platform.
Locknuts

Accurate inspection of the carriage alignment can be done by measuring the distance
behind each drive motor from the rear carriage
bar to the rear housing (L3 and L4 in Photo
Z). Comparing the two distances, increase
the chain tension on the side of the longest
distance, via the tension locknut, 1/2 turn
for each 1mm difference. Cycle the ramp
several times, observing the full out alignment of the ramp with the bus threshold.
Stopping once again at the fully deployed
position re-measure the distance behind each
drive motor from the rear carriage bar to the
rear housing and adjust the chain tension accordingly until the full out alignment from side
to side is within ±1mm. Note: If the chain
tension of one side is overly increased, it may
result in a binding condition of the track rollers in the guide rail and lead to obstructions
sensed by the control box.
