Introduction
The Braun RA500 In-Floor Ramp
(to be referred to as RA500
throughout this manual) is designed for use in low-floor transit
vehicles. The RA500 provides
vehicle access to people with
disabilities (wheelchair passengers or standees using other type
mobility aids).
The self-contained “drop-in” electric unit requires no pre-assembly.
The electrical components are
internal and easily accessible.
The RA500 features a 32” wide
ramp in a 38” wide package. A
“floor pocket” built into the chassis/floor system allows for simple
installation (dimensional requirements specified in the Installation
section).
The RA500 is specifically designed to be operated by an
attendant. The ramp is controlled
by either a “one-touch control” or
a “press and hold control”.
Page The RA500 provides fully automatic operation of ramp functions.
The electric system is controlled
by a electronic controller board
which activates an electric motor
in opposite directions for deploy
and stow functions (powering a
chain drive system).
Obstruction sensing is a standard
feature with the RA500 ramp.
The RA500 also has an optional
weight sensitive pad on the ramp
platform. The ramp will not
operate with 15 kilograms on the
platform when equipped with the
weight sensitive pad.
Instructions are provided for
manual operation of the ramp
in event of power or equipment
failure. See Manual Override for
further details.
Read and become familiar with
all operation safety precautions,
pre-operation notes and details,
operating instructions and manual
operating instructions before attempting operation.
Terminology: Become familiar
with the terminology that will be
used throughout this manual.
Become familiar with the identification of RA500 components
and their functions. Contact your
sales representative or call The
Braun Corporation at 1-800-THE
LIFT® if any of this information is
not fully understood.
Direction: The terms “left”,
“right”, “in” and “out” will be used
throughout this manual to indicate
direction (as viewed from the outside of the vehicle looking directly
at the ramp). Refer to the Terminology Illustrations for clarification
of direction terms.
RAMP TERMINOLOGY
Ramp Components
Refer to the Terminology Illustrations 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 the
control box is commonly referred
to as the “controller”.
Pan Weldment (Housing):
The pan is the aluminum (casing)
mounted in the vehicle floor system which contains the electrical
components that power the ramp
electrical systems. The fixed
sub-floor cover protects the components from above. The cover
is easily removed for access to
drive components. The sub-floor
provides an antiskid surface for
entry and exit when the ramp
is deployed. The RA500 ramp
stows into the sub floor
providing an unobstructed antiskid surface for entry and exit
when the ramp is not in use.
Stowed Position: Stowed
position is achieved when the
ramp platform assembly is fully
retracted (resting fully in the pan
weldment).
Obstruction Sensing: An obstruction sensing feature is standard with the RA500 ramp. The
controller monitors the instantaneous movement of the electric
motor, and calculates a “real time”
running average of the current. It
then compares the programmed
peak (maximum vs. instantaneous) and delta (instantaneous
minus running average) limits to
determine if an obstruction has
been encountered.
Ramp Platform: The ramp
platform is the aluminum ramp
section assembly featuring a full
antiskid surface.
Chain Drive Assembly: The
electric motor driven chain drive
deploys and stows the ramp platform assembly.
Ramp Actions and Functions
Extend: Extend is the action of
the platform moving out of the
pan weldment (housing).
Retract: Retract is the action of
the platform moving in to the pan
weldment (housing).
Deploy: Deploy is the action of
the ramp assembly extending to
ground level when the DEPLOY
(OUT) switch is activated.
Stow: Stow is the action of the
ramp assembly retracting inward
to the stowed position when the
STOW (IN) switch is activated.
Note: the one touch controller activates both the stow and
deploy functions, dependant upon
the state of the RA500.
Manual Override: Manual
operation is achieved through
the use of a mechanical release.
Simply pull the release and use
the hand hold provided on the
ramp platform to manually deploy
or stow the ramp. Minimal physical effort is required to stow and
deploy the ramp platform. Slow
steady motion results in the least
resistance and easy operation.
See pages 12 and 13 for detailed
manual release procedure.
Weight Sensing Pad (optional):
The platform can be equipped
with a weight sensing pad. This
optional feature will cause the
ramp not to operate in the event
that 15 kilograms or more is on
the ramp platform.

Page RAMP OPERATION
Operation Notes and Details
The RA500 ramp provides vehicle
access to people with disabilities
(wheelchair passengers or standees using other type mobility
aids). The commercial oriented
RA500 ramp is operated by the
transit vehicle driver/attendant.
Unless your transit agency has
a published policy stating that
driver/attendants do not aid ramp
passengers, safe entering and
exiting of ramp passengers is
the responsibility of the driver/
attendant.
As stated in the Ramp Operation
Safety section, all information in
this manual is provided for the
safety of passengers, attendants
and bystanders. Recognize the
seriousness of this information.
Read and become familiar with
all ramp operation safety precautions, pre-operation notes and
details, operating instructions and
manual operating instructions
before attempting ramp operation procedures or assisting ramp
passengers boarding and exiting
the vehicle.
Ramp Access Doors and Interlocks
Attendants must become familiar
with the vehicle ramp access door
system and interlock(s), as well
as the proper operation of the
ramp.
Vehicle ramp access door configurations and operation procedures vary. Ensure the ramp door
is fully open before activating the
ramp (an interlock typically prevents ramp operation unless the
door is fully open). Attendants
and passengers must keep clear
of the area in which the power
door operates. Ensure the path
is clear before closing the door.
Be sure the door is fully closed
before attempting to drive the vehicle (interlocks typically ensure
this).
Page Interlocks are required by nearly
all transit authorities. Vehicle
interlocks typically prevent vehicle
motion if the ramp is not stowed.
In some cases, the ramp cannot
be operated if interlock conditions
are not met. Interlock requirements may include: the vehicle
transmission must be engaged in
Park, the parking brake must be
engaged, the ramp access door
must be fully open and/or others.
Multiple interlocks may exist.
Instructions for operation of interlocks and door systems cannot be
addressed in this manual due to
the variety of procedures required
for operating them.
General instructions for safe
operation of the ramp are provided. Ramp safety and ramp
passenger safety information is
included. It is the responsibility of the attendant to properly
open and close the ramp access
door(s), to activate interlock(s), to
properly activate the ramp power
functions as well as assist ramp
passengers.
Do not operate the ramp if you
suspect ramp damage, wear or
any abnormal condition. Discontinue use immediately and
contact The Braun Corporation
at 1-800-THE LIFT®. One of our
national Product Support representatives will direct you to an
authorized service technician who
will inspect the ramp.
RAMP OPERATION
Operation Procedure Review
The Braun Corporation recommends that transit agency supervisors and driver/attendants
review the safety precautions and
operation procedures appearing
in this manual with the ramp sales
representative (or vehicle converter) before attempting ramp
operation.
Any questions or concerns can be
answered at that time. Operate
the ramp through all functions to
ensure the proper use and operation is understood.
Transit agency supervisors
should train and educate all
driver/attendants on the proper
use and operation of the vehicle,
door system, interlock(s), ramp
and ramp passenger safety.
The ramp owner’s/service manual must be stored in the rampequipped vehicle at all times.
WARNING
Read and become
familiar with all ramp
operation safety
precautions, preoperation notes and
details, operating
instructions and
manual operating
instructions prior to
operating the ramp.
If this information is
not fully understood,
contact The Braun
Corporation immediately. Failure to do so
may result in serious
bodily injury and/or
property damage.
Preventive Maintenance:
Maintenance is necessary to
ensure safe and trouble free
operation. General preventive
maintenance consisting of careful inspections and cleaning the
ramp system should be a part of
your transit agency’s daily service
program. Simple inspections
can detect potential operational
problems.
Regular preventive maintenance
will reduce potential operation
downtime and increase the
service life of the ramp, as well
as possibly detecting potential
hazards.
A generic Daily Preventive
Maintenance Schedule is
provided in this manual for your
transit agency’s use. The form
can be tailored to your particular
application.
Exposure to harsh weather, environmental conditions, or heavy
usage may require more frequent
maintenance and lubrication
procedures.
Preventive maintenance visual
inspections do not take the place
of the procedures specified in
the Maintenance and Lubrication
Schedule provided in this manual.
Refer to the Maintenance and
Lubrication section in this manual
for further details.
Page RAMP OPERATION
Ramp Power Operation
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 either a ground
(-) or (+) signal be supplied, one
of these signals is required but
not both. This signal interlocks
the ramp functions. 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 stop, and
the controller will not function any
further until the interlock signal is
present once again.
Page 10
Operator Input Switches: The
RA500 Ramp electronic controller
provides fully automatic operation
of all ramp functions. Ramp functions can be performed from any
position the platform assembly
happens to be in at the time the
operator input switch is activated.
The ramp is protected by a standard obstruction sensing feature.
One-Touch Operation: In onetouch mode, the ramp will deploy
if fully stowed. If the ramp is in
any other position the ramp will
stow. The ramp function will continue until the switch is pressed
again (indicating stop immediately), the unit reaches the end of
travel, or a “halt condition” occurs
(see Halt Conditions).
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 RA500 ramp 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)
• Optional platform weight sensing pad senses a load equal to
or greater than 15 kilograms
(details below)
• End of travel reached
Obstructions: The controller
performs obstruction sensing
(see RA500 ramp Terminology:
Obstruction Sensing) on all stow
and deploy movements of the
ramp. The selected obstruction
response mode configured in
the controller during installation,
either immediately stops the present movement when obstructed,
or stops and then reverses
movement for 1 second. Once an
obstruction has halted the ramp,
the controller automatically resets
and awaits operator input for
further operation.
Weight Sensing Pad (optional):
The platform can be equipped
with a weight sensing pad. This
optional feature will cause the
ramp not to operate in the event
that 15 kilograms or more is on
the ramp platform.
RAMP OPERATION
Power Ramp Safety
Be certain there is adequate
clearance outside the vehicle before deploying the power ramp.
The ramp operator (attendant)
and bystanders must keep clear
of the area in which the ramp
operates and clear of all moving
parts. Attendants must ensure
that passengers keep clear of the
area in which the ramp operates.
Do not attempt to grip or hold the
ramp.
If you are an attendant operating
the ramp, it is your responsibility to oversee and/or assist in
performing safe passenger loading and unloading procedures.

RAMP OPERATION
Ramp Passenger Safety
Unless your transit agency has
a published policy stating that
driver/attendants do not aid ramp
(disabled) passengers, it is the
responsibility of the driver/attendant to ensure that ramp
passengers enter and exit the
vehicle on the ramp in the safest manner.
ADA requirements state that transit drivers/attendants must assist
with attaching and removing
wheelchair and occupant restraint
belts.
stability, balance, weight distribution and use of attendants as
specified in the owner’s manual
supplied with the passenger’s
wheelchair (or other mobility aid).
Wheelchair passengers must
determine, establish and practice
ramp boarding and exiting procedures under the direction of the
their personal health care professional and wheelchair representative. Those procedures should be
conveyed to the ramp attendant.
Know your passengers abilities
and needs for optimum safety.
Different types of disabilities
require different types of wheelchairs and different types of
wheelchair-equipped occupant
restraint belt systems (torso restraint). It is the responsibility of
the wheelchair passenger to have
his or her wheelchair equipped
with an occupant restraint (seat
belt) under the direction of their
health care professional.
Stabilizing Wheelchairs: Powered and manual wheelchairs
are designed to remain upright
and stable during normal operation. All activities which involve
movement in a wheelchair have
an effect on the combined center
of gravity of the occupant and
wheelchair. Be aware of the ramp
slope (angle). The slope of the
ramp has a direct effect on the
center of gravity. The wheelchair
passenger’s center of gravity and
their ability to maintain stability
and balance must be kept in mind
by the wheelchair passenger and
the attendant.
Ramp passengers (wheelchair
passengers and standees), and
attendants must use common
sense and good judgment regarding ramp safety. Each wheelchair
passenger (or standee) has a
unique set of physical abilities
combined with the physical characteristics of his or her wheelchair
(or other mobility aid) that dictate
the method in which he or she will
enter and exit the vehicle.
Attendants must never operate
the vehicle, the ramp or assist
passengers if intoxicated. Intoxicated passengers should not
be allowed to board or exit the
vehicle.
Wheelchair attendants should be
instructed on any special needs
and/or procedures required for
safe transport of wheelchair passengers. Follow all safety instructions regarding torso restraints,

RAMP OPERATION
Ramp Passenger Safety
Wheelchairs should be operated
at a slow and constant speed
when on the ramp. Wheelchairs
should not accelerate suddenly
when on the ramp. Wheelchair
passengers should not raise the
front wheelchair wheels (pull
wheelie) when on the ramp.
Wheelchair passengers who
intend to enter and exit the
vehicle without the assistance of
an attendant must determine the
safest and most practical method
and orientation of entering and
exiting based on the physical
characteristics of their personal
wheelchair and his or her physical
capabilities to maintain stability
while the wheelchair is in motion
on the ramp.
Wheelchair Attendants: When
assisting a wheelchair occupant,
remember to use good body mechanics. When the wheelchair is
on the ramp, the attendant must
grasp the push handles (or other)
securely. Detachable wheelchair
parts such as arms or leg rests
must never be used for hand
holds or lifting supports. Doing
so could result in the parts being
inadvertently detached from the
wheelchair resulting in possible
injury to the wheelchair occupant and/or the attendant.

Installation Requirements
Braun RA500 Ramp must be
installed and serviced by a Braun
authorized service representative who has attended and been
certified by The Braun Corporation Sales and Service School for
Braun Mobility Products.
Read and become familiar with
the operating instructions and the
installation instructions contained
in this manual before beginning
installation, operation or service
procedures.
WARNING
Read this manual
before performing
installation, operation
or service procedures.
Failure to do so may
result in serious
bodily injury and/or
property damage.
Chassis Requirements
The Braun RA500 Ramp is
designed for use in low-floor
transit vehicles. A “floor pocket”
(mounting hole) built into the
chassis/floor system allows for
simple installation (accepts “dropin” unit). The Floor Pocket Clear
Opening Dimensions on the
following pages.
Outboard Support Tube: An
outboard support tube must be
positioned under the outboard
edge of the opening (minimum
40mm x 50mm steel tube). See
Figure F. The recommended
maximum height of the support
tube is 210mm above ground
level.
An optional RA500 model without
the fixed sub floor is available.
When installing this model the
vehicle floor is installed above
the ramp assembly. This model
is designed to be installed above
the frame, but below the vehicle
floor. This model does not have
the fixed sub floor on top of the
assembly.
Kneeling Vehicles: 210mm is
the maximum dimension measured with suspension lowered.
The ramp installer must provide
an appropriate framework in the
applicable location in the vehicle
(aligned center with passenger
door opening). Ramp assembly
mounting hardware and/or bracketry are directly dependant upon
the vehicle chassis and “floor
pocket” configuration (not supplied).
Page 18
EU: Installations with the support tube positioned higher than
210mm above ground level may
not comply with EU ramp slope
requirements.
Some OEM chassis meet these
specifications. The RA500 ramp
was designed to conform to these
specifications.
The ramp pan horizontal border (lip) sets on the floor pocket
perimeter (framework, sub floor,
etc.). The finished flooring can be
cut to conform to the border of the
pan for a flush transition surface
from ramp-to-floor. The finished
flooring can also go over the top
of the ramp if the optional ramp
model with out the fixed sub floor
is installed.
Door Opening: Open the door(s)
fully and check the clear door
opening width dimension. Specified minimum clear door opening width must be provided
(850mm for 825mm ramp).
Door(s) must open outward.
When closed, the door(s) should
align with and conform to the
outboard edge of the ramp pan
(rubber seal on bottom of door).
Minimum Clear Door Opening
Dimensions are defined as finished door opening, including any
intrusive door jambs, headers,
sills or hinges.
Obstructions: Any intrusive obstructions within the door opening
or the ramp mounting/operating
area (such as seats, molding,
lights, brackets, etc.) must be
removed. Trim or molding that
creates an uneven mounting surface should be removed.

MAINTENANCE and LUBRICATION
Maintenance and Lubrication Introduction
Proper maintenance is necessary to ensure safe,
trouble-free operation. Inspecting the ramp for
any wear, damage or other abnormal conditions
should be a part of all transit agencies daily service
program (preventive maintenance). Simple inspections can detect potential problems.
A generic Daily Preventive Maintenance Schedule is provided in this manual for transit agency
use. The form can be tailored to your particular
application. Preventive maintenance visual inspections do not take the place of the procedures specified in this schedule.
The maintenance and lubrication procedures specified in this schedule must be performed by a Braun
authorized service representative at the scheduled
intervals according to the number of cycles or
elapsed time, whichever comes first.
RA500 ramps are equipped with hardened pins and
self-lubricating bearings to decrease wear, provide
smooth operation and extend the service life of the
ramp.
Clean the components and the surrounding area
before applying lubricants. LPS2 General Purpose Penetrating Oil is recommended where Light
Oil is called out. Use of improper lubricants can
attract dirt or other contaminants which could result
in wear or damage to the components. Ramp components exposed to contaminants when lowered to
the ground may require extra attention. Specified
lubricants are available from The Braun Corporation
(part numbers provided on page 30).
Recommended Intervals: These intervals are a
general guideline for scheduling maintenance pro-
cedures and will vary
according to ramp use
and conditions. Transit
agencies operating
vehicles equipped with
ramps that are not
monitored by cycles
may choose to have
the ramp system maintained on the same
schedule as the vehicle
(routine maintenance).
Doing so ensures the
ramp is being maintained regularly.
WARNING
Maintenance and lubrication procedures
must be performed
as specified by an
authorized service
technician.
Failure to do so may
result in serious
bodily injury and/or
property damage.
When servicing the ramp at the consecutive recommended intervals, inspection and lubrication procedures specified in the previous sections should be
performed (repeated). All listed inspection, lubrication
and maintenance procedures should be repeated at “8
Weeks or 200 Cycles” intervals following the scheduled
“1 Year or 1250 Cycles” maintenance.
Lifts exposed to severe conditions (weather, environment, contamination, heavy usage, etc.) may require
inspection and maintenance procedures to be performed more often than specified.
Discontinue ramp use immediately if maintenance
and lubrication procedures are not properly performed,
or if there is any sign of wear, damage or improper
operation. Contact your sales representative or call
The Braun Corporation at 1-800-THE LIFT®. One of
our national Product Support representatives will direct
you to an authorized service technician who will inspect
your ramp.

Electrical
WARNING
Improper microswitch
adjustment may
result in serious
bodily injury and/or
property damage.
Microswitches: Three microswitches (limit switches) are incorporated in the RA500 electrical
system (IN-Limit, OUT-Limit and
Manual Release signal). Details
and illustrations of the microswitches are provided. Adjust
microswitch (es) as detailed.
Note: Under normal circumstances the RA500 microswitches
should not need adjustment. If
adjustment or replacement is
required, follow the procedures
provide on the next page.
Deployed Position: When the
ramp is in the deployed position,
the OUT-Limit microswitch is activated. In contrast, the IN-Limit
microswitch is deactivated.
Manual Release State: When
the ramp’s manual release is
engaged the manual release
microswitch signals the controller that the manual release state
of the ramp has been engaged.
This signals the controller to disable the power functions of the
RA500.
Microswitch Sequence
Stowed Position: When the
ramp is in the stowed position, the IN-Limit microswitch is
activated (common and normally
open terminals have continuity).
In contrast, the OUT-LImit microswitch is deactivated.
Deploy Sequence: When the
ramp is in the stowed position,
the OUT-Limit microswitch is deactivated, and thus allows current
to pass from the vehicle’s Deploy
switch circuit and energize the
ramp’s Bidirectional motor in the
deploy direction (motor drives
chains to deploy ramp).
Stow Sequence: When the ramp
is in the deployed position, the INLimit microswitch is deactivated ,
allowing current to pass from the
vehicle’s Stow switch circuit and
energize the ramp’s Bidirectional
motor in the stow direction (motor
drives chains to stow ramp).
OUT-Limit Microswitch
The OUT-Limit microswitch is located in the outboard mounting position of the platform carrier plate.
To adjust:
1. Power or manually move the ramp to the full out
position.
OUT-Limit
Microswitch
2. With the ramp in the deployed position loosen
the OUT-Limit microswitch mounting screws.
3. Slide the switch body outward until resistance is
