RAMP TERMINOLOGY
Introduction

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 control- ler activates both the stow and
deploy functions, dependant upon the state of the RA500.
Stowed Position: Stowed position is achieved when the ramp platform assembly is fully retracted (resting fully in the pan weldment).
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 physi- cal 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.
Obstruction Sensing: An ob- struction sensing feature is stan- dard with the RA500 ramp. The controller monitors the instanta- neous movement of the electric motor, and calculates a ???real time??? running average of the current. It then compares the programmed peak (maximum vs. instanta- neous) and delta (instantaneous minus running average) limits to determine if an obstruction has been encountered.
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
Operation Notes and Details
The RA500 ramp provides vehicle access to people with disabilities (wheelchair passengers or stand- ees 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 precau- tions,
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 con- figurations and operation proce- dures vary. Ensure the ramp door is fully open before activating the ramp (an interlock typically pre- vents 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 ve- hicle (interlocks typically ensure this).
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 require- ments 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 inter- locks 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 pro- vided. Ramp safety and ramp passenger safety information is included. It is the responsibil- ity 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. Dis- continue use immediately and contact The Braun Corporation at
Page
Preventive Maintenance:
Maintenance is necessary to ensure safe and trouble free operation. General preventive maintenance consisting of care- ful 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, en- vironmental 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.

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/at- tendant to ensure that ramp passengers enter and exit the vehicle on the ramp in the saf- est manner.
ADA requirements state that tran- sit drivers/attendants must assist with attaching and removing wheelchair and occupant restraint belts.
Ramp passengers (wheelchair passengers and standees), and attendants must use common sense and good judgment regard- ing ramp safety. Each wheelchair passenger (or standee) has a unique set of physical abilities combined with the physical char- acteristics of his or her wheelchair (or other mobility aid) that dictate the method in which he or she will enter and exit the vehicle.
Wheelchair attendants should be instructed on any special needs and/or procedures required for safe transport of wheelchair pas- sengers. Follow all safety instruc- tions regarding torso restraints,
WARNING
stability, balance, weight distri- bution 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 proce- dures under the direction of the their personal health care profes- sional and wheelchair representa- tive. Those procedures should be conveyed to the ramp attendant. Know your passengers abilities and needs for optimum safety.
Attendants must never operate the vehicle, the ramp or assist passengers if intoxicated. In- toxicated passengers should not be allowed to board or exit the vehicle.
Passengers should be positioned in the center of the ramp at all times. Attendants and ramp pas- sengers must be able to clearly view the ramp whenever boarding and exiting the vehicle. Observe your passengers at all times when they are entering and exiting the vehicle.
Different types of disabilities require different types of wheel- chairs and different types of
Stabilizing Wheelchairs: Pow- ered and manual wheelchairs are designed to remain upright and stable during normal opera- tion. 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.
The aid of an attendant stabilizing the wheelchair is recommended for optimum safety. Wheelchair passengers who are unable to maintain stability and balance should not board a ramp without assistance. Counterbalance devices
Position and fasten the wheelchair- equipped occupant seat belt before loading onto the wheelchair ramp. Failure to do so may result in serious bodily injury and/or property damage.
WARNING
Be aware of ramp slope.

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 me- chanics. 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 occu- pant and/or the attendant.

Maintenance and Lubrication Introduction
Proper maintenance is necessary to ensure safe,
A generic Daily Preventive Maintenance Sched- ule is provided in this manual for transit agency use. The form can be tailored to your particular application. Preventive maintenance visual inspec- tions do not take the place of the procedures speci- fied in this schedule.
The maintenance and lubrication procedures speci- fied 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
Clean the components and the surrounding area before applying lubricants. LPS2 General Pur- pose 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 com- ponents 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 main- tained on the same schedule as the vehicle (routine maintenance). Doing so ensures the ramp is being main-
tained regularly.
When servicing the ramp at the consecutive recom- mended intervals, inspection and lubrication proce- dures 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, environ- ment, contamination, heavy usage, etc.) may require inspection and maintenance procedures to be per- formed 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

Page 34
SYSTEMS DESCRIPTIONS
Manual Calibration Instructions for Controller
Press the ???Calibrate??? button. Once pressed, the calibrate LED should turn on.
Adjust the Deploy Limit potentiometer to the obstruc- tion sensing level desired (see Figure S). Rotating the potentiometer counterclockwise increases the force that the ramp will exert when it is deploying.
Caution: Ensure that the force exerted is not exces- sive. It is recommended to adjust the potentiometer in small amounts and check operation after each adjustment.
Adjust the Stow Limit potentiometer to the obstruc- tion sensing level desired. Rotating the potentiom- eter counterclockwise increases the force that the ramp will exert when it is stowing.
Caution: Ensure that the force exerted is not exces- sive. It is recommended to adjust the potentiometer in small amounts and check operation after each adjustment.
Once the desired force levels are reached, press the ???Calibrate??? button a second time to store the set- tings. Ensure the calibrate LED is off before return- ing the ramp to service.
