SPECIFICATIONS & OVERVIEW The Right Weigh 201-EBT-04B digital load scale has four internal air pressure sensors. This scale can monitor a tandem axle air suspension drive group where all 4 air bags can have differing pressures. The 4 pressures are averaged together so that a weight can be properly calculated.

SPECIFICATIONS & OVERVIEW Estimated Steer Axle: The weight of the steer axle can be estimated if this scale is used to monitor a tractor's drive axle group. Refer to the Sensor Average + Estimated Steer or Independent + Estimated Steer Mode sections for more information. Estimated Steer is for use on tractors only, it will NOT work on straight trucks.

INFORMATION RWLS APP It is required that the operator use the Right Weigh App to connect to all MSU’s (gauges) on the vehicle. If the operator is driving a vehicle with more than one MSU, the MSU’s must be added within the app in front to back order. Bluetooth connection must be maintained with all MSU’s on the vehicle in order for the weight information...
SCALE INSTALLATION & ELECTRICAL CONNECTIONS The 201-EBT-04 scale is designed to be mounted on the outside of a truck or trailer, however it must still be mounted in a protective enclosure. A protective box and mounting bracket are included with the 201-EBT-04B. The following steps will walk you through how to correctly mount and install the scale.

SCALE INSTALLATION & ELECTRICAL CONNECTIONS CUT EXISTING AIR LINE Cut the air line going to one of the air bags in the suspension group to be monitored. ASSEMBLE TEE FITTING Choose a tee fitting that matches the size of the existing air line, then install a female NPT tube fitting onto the tee as shown.

These connections are used to send data to and from a Right Weigh remote trailer sensor or other Right Weigh gauge (use is optional, see page 13 for more information). Connect these to the remote trailer connection harness included in kit 224-SK if using the Drop &...
When installed on a tractor's drive axle group with four HCVs, the 201-EBT-04(B) can also display a trailer axle group weight if used in conjunction with Right Weigh remote trailer sensor (RTSK-01*) and connection harnesses (224-SK** & EL-004-0049**). The 224-SK and EL-004-0049 connection harnesses must be installed on the tractor to allow for connection to the remote trailer sensor.

DROP & HOOK TRAILER ENABLE FEATURE ON SCALE With the scale OFF, press and hold PRESS both the UP arrow and MENU buttons and then press the ON/OFF button. Release all 3 buttons. The scale will display “A4”. This means the scale has FOUR air sensors.
OPERATING MODES The next few pages cover the operation modes that are built into the 201-EBT-04(B). The load scale can only be setup in one operating mode at a time. If the mode is changed, the calibration data will be reset to factory defaults, requiring re-calibration.
OPERATING MODES SENSOR AVERAGE (AVG) Drop & Hook Trailer Feature Off In Sensor Average mode, a 201-EBT-04(B) installed on an axle group with four HCVs will display one weight reading for only the axle group it is connected to. Drop & Hook Trailer Feature On If the scale has been installed on a drive axle group and configured to use the remote trailer sensor, the scale will also read out a single weight for the trailer axle group.
OPERATING MODES MULTIPLE CALIBRATION MODE (4CAL) The 201-EBT-04(B) digital load scale in Multiple Calibration mode (4CAL) can store four sets of calibration data. This can be useful for an axle group which has one or more integrated air ride lift axle(s) using the same four HCVs, or a suspension which has many operating conditions.

The following is a list of additional parts needed for air line installation. This list is just a suggestion and may not be all of the parts needed for your specific vehicle. Check with your Right Weigh dealer for optional installation kits.
APPENDIX B It is important that all wiring connections be made watertight. Connections which are not watertight can develop corrosion and result in loss of contact over time. Heat shrink type butt connectors are recommended. Crimp each end of the wire into the connector with a wire crimp tool (tool not provided).
APPENDIX C GENERAL APP INFORMATION Be sure to add the scales on the app in the correct order (front to back). SCALE 1 SCALE 2 SCALE 3 If the trailer scales are in the wrong order, delete them and re-add them in the correct order.
