Installation Instructions ER1301WS Installation: Parts List (ER1319): Braun ER1301WS electronic controller 100465-002 is exclusive for Weight Sensor ramps. Install Weight Sensor RA200 models as outlined in this section. Item Qty. 1 1 Description Control Box - ER1301WS Part No. 100465-002 Installation Procedures: 1. Mount ramp assembly using the eight holes shown in Photo C. Mounting hardware must be minimum 7/16" or 12mm diameter.
Installation Instructions User Inputs/Outputs The weight sensor controller has five required user inputs and five optional user outputs. At least four user inputs are required to be connected in order for the ramp to function, whereas none of the user outputs must be connected (optional). Below is a list of the user inputs and outputs, including the designated connector pin number, wire color, and description.
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.
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.
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.
Manual Operating Instructions 5. Turn (tighten) the “T” handle 90° to secure handle in the engaged (locked) position. 6. Verify mechanism is reengaged (locked). View customer installed sensor LED, or pull on the Hand Hold to ensure no movement occurs. 7. Stow the remaining portion of the platform by using the electrical system. To Manually Raise or Lower Ramp: 1. Raise and hold platform assembly up to gain access to the self-locking release pin. 2.
Maintenance, Lubrication & Adjustments Exterior Maintenance and Lubrication frame. A de-greasing agent and brush may be used if necessary to remove large buildups. Do not spray water directly into cassette or at the electrical connectors . Clean away debris that may be built up in beeper that may reduce or prohibit audibility. Note: In order to ensure proper and consistent performance of the Braun RA200, routine maintenance in the form of cleaning, lubricating, inspecting, and adjusting is essential.
Maintenance, Lubrication & Adjustments Exterior Maintenance and Lubrication (continued) Front Cover Hinge: The front cover opens and closes via a spring loaded hinge. See Photo E. Clean and lubricate the front cover hinge. A light oil may be used on the front cover hinge but should be limited to reduce the possible buildup of debris. Allow hinge to dry before applying lubricant (light oil).
Maintenance, Lubrication & Adjustments Exterior Adjustments (continued) Floor Level Sensor Stow Level Sensor Photo H Photo I 2 MM 2 MM Floor Level Pick-Up Set Screw 1. The floor level (up) sensor pick-up (see Photo H) should be adjusted (via the set screw) 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.
Maintenance, Lubrication & Adjustments Exterior Adjustments (continued) 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).
Maintenance, Lubrication & Adjustments 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.
Maintenance, Lubrication & Adjustments Interior Adjustments Photo Q Overall View Full Out/Deployed Positional Sensor Photo R Pick-Up Plate Full In/Full Out Position of Carriage: The carriage houses two sensors that provide positional feedback of full out (see Photo R) or full in/stowed (see Photo S) for the carriage and platform assembly. The proximity sensors switch on and off as the sensor head passes over a metallic pick-up plate mounted on the cassette frame.
Maintenance, Lubrication & Adjustments Interior Adjustments (continued) Manual Release System: If the release cable is difficult to pull to unlock the system, inspect the guide and slider shown in Photo T. Manual Release (dotted lines represent deployment) Photo T Confirm no dirt, metal shavings, or other foreign debris are present and restricting the slider. Also, check compression spring to verify the open end of the spring is not binding the movement of the slider.
Maintenance, Lubrication & Adjustments Interior Adjustments (continued) Chain Tension: Equal tension on the left and right drive chains is necessary to reduce binding effects on the carriage bearings and allow for smooth movement throughout the in/out cycle. An excessively loose chain may enable the drive sprocket to “jump” teeth, thus providing a binding situation.
Maintenance, Lubrication & Adjustments Interior Adjustments (continued) 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.
Inspection List Exterior Inspection Below is a list of routine inspections which should be done to ensure optimal ramp performance and prevent excessive wear leading to poor operation and possible component failure. Refer to the specified pages within this manual for further details. These ramp inspections should be performed if the ramp has unusual malfunctions, the bus is undergo- Inspect For What ing routine service, or after every 500 completed cycles, whichever comes first.
