Braun RA200 service manual Operation

Operation

Pre-Operation Notes

Operation Procedure Review: The RA200 operator should re- view 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 pro- cedures, 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 imme- diately and contact an authorized Braun representative.

Preventative Maintenance: Maintenance is necessary to ensure safe and trouble-free ramp operation. General preven- tative maintenance consisting of inspecting, cleaning and lubricat- ing procedures should be part of a scheduled routine. Simple inspections can detect poten- tial ramp operational problems. Adjustments can be made as needed (details in Maintenance and Adjustments section).

Regular preventative mainte- nance will reduce potential ramp operation downtime and increase the service life and reliability of the ramp, as well as enhanc- ing safety. Exposure to harsh weather elements, environmental conditions or heavy usage may require more frequent mainte-

nance and lubricating procedures. See the Maintenance and Adjust- ments section for more detailed information.

Cold Climate Recommenda- tions: The vehicle in which the ramp has been installed should be stored in a garage or other sheltered place if possible, espe- cially 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 materi- als from entering the ramp open- ing 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 bound- less variations in application and installation of the ramp. Manual Operating Instructions are ad- dressed in the event of power or equipment failure.

Before Operating Ramp: Al- ways 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 sig- nal be supplied which interlocks the ramp functions with a cus- tomer 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 plat- form assembly will automatically complete the ‘full stow’ sequence,

and the controller will not func- tion any further until the interlock signal is present once again.

Operator Input Switches: The RA200 electronic controller pro- vides fully automatic operation of all ramp functions, which are pro- tected 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 (con- tinuous 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 condi- tion” occurs (details follow).

Halt Conditions: Several condi- tions can cause a normal se- quence to terminate (stop):

•Obstructions (details below)

•Customer Interlock signal lost (see Customer Interlock)

•Manual Release System ‘un- locked’ 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 nor- mally or with the manual override switches. The selected obstruc- tion response mode configured
