SCALE INSTALLATION & ELECTRICAL CONNECTIONS

INSTALL STRAIN SENSOR

Follow the steps on the included 218-SK or 221-SK installation kit manual to install all strain sensors onto the vehicle

CHOOSE LOCATION

The 201 series 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 series scale

Be sure to choose a location that is easily accessible and safe from potential damage (forklift posts, tire caps, etc

DO NOT mount the scale directly to the chassis or any other main beam unless it is approved by the vehicle manufacturer. Doing so may void the warranty with the vehicle manufacturer

INSTALL CONNECTION HARNESS

Follow the steps on the included 226-SK, 228-SK, or 229-SK installation kit manual to install the connection harness

SET NUMBER OF CONNECTED STRAIN SENSORS

Once the gauge is connected to power, it will automatically turn on and display “bAr -” on the screen. Set the gauge to the
number of strain sensors that are connected to the gauge using the UP arrow button

• bAr 0 = 0 strain sensors
• bAr 1 = 1 strain sensor
• bAr 2 = 2 strain sensors
• bAr 3 = 3 strain sensors (not applicable – will result in set up error)

If you need to change the number of strain sensors at any point, follow these steps

1. Turn off the scale
2. Press and hold the C HIGH button and the MENU button, press the POWER button, then release all 3
3. Use the UP arrow button to change the number of strain sensors to the number desired
4. Turn off the scale to save setting

OPERATING MODES

Each vehicle configuration requires a specific operating mode. The modes available on this gauge are

AVG – Straight Truck, Tractor, or Trailer (One Axle Group)
IdP – Straight Truck, Tractor, or Trailer (Separate Axle Weights)
F1b2 – Trailer with One Front Axle and Two Rear Axles or Straight Truck with Spring Steer and Walking Beam Drive Suspension
See the tables on the following pages to find your vehicle configuration and set the gauge to the corresponding operating mode

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

SENSOR CHECK & ADJUSTMENT

At this time, you should have the scale and all strain sensors installed onto the vehicle. Once this is complete, it is time to adjust the strain sensor(s).

ENTER DIAGNOSTICS MENU

With the scale turned off, hold down the MENU button and then press the ON/OFF button – release both at the same time. This will display the software version on the scale

CHECK SENSOR VALUES

Press the MENU button three times; a four digit number will appear representing the raw output from sensor A. For applications with multiple sensors, hit the UP ARROW to see the values for sensors B and C

ADJUST STRAIN SENSOR

• In this example, strain sensor A is out of range and needs to be manually adjusted until it is between 6.500 and 7.500.

• With the gauge displaying the sensor value that needs adjusted, remove the sheet metal cover of the corresponding strain sensor

• Find the mounting block with TWO set screws and loosen one set screw. GENTLY push the end of the sensor bar with an appropriate tool

• Pushing inward will lower the number and pushing outward will raise the number
  NOTE: It takes a very small amount of force to adjust the sensor

• While holding the sensor bar in place, tighten both set screws and re-check the display. It may take a moment for the scale to settle on a number. Repeat process until range is within 6.500 and 7.500.

SENSOR CHECK & ADJUSTMENT

CALIBRATION & UNITS

CHANGING UNITS

With the gauge on, press and hold the UP ARROW and then press the MENU button. This will toggle the settings between pounds and kilograms

CALIBRATION

The 201 series load scale must be calibrated both empty and loaded to work properly. The scale associates the weight you enter with the air pressure in the suspension system at the time of calibration. You will need to calibrate once while the vehicle is empty, and again while the vehicle is loaded for each axle group being monitored.

EMPTY CALIBRATION POINT

1. While the vehicle is empty, obtain axle group weights from a certified in-ground scale.
2. Park on a level surface. Shift the transmission to neutral and set the parking brakes. Chock the wheels to prevent unexpected vehicle movement, then release the parking and service brakes
3. Press the ON/OFF button to turn on the Right Weigh load scale.
4. Press the blue MENU button to select the proper axle group or calibration set.
5. Press and hold the C LOW button until the “C/L” symbol appears.
6. Adjust the value using the UP and DOWN arrows so that it matches your scale ticket for the axle group.
7. To save, press and hold the C LOW button until the “C/L” symbol disappears

LOADED CALIBRATION POINT

3: Press the ON/OFF button to turn on the Right Weigh load scale.
4: Press the blue MENU button to select the proper axle group or calibration set.
5: Press and hold the C HIGH button until the “C/H” symbol appears.
6: Adjust the value using the UP and DOWN arrows so that it matches your scale ticket for the axle group.
7: To save, press and hold the C HIGH button until the “C/H” symbol disappears

9: Repeat steps 4-7 for all axle groups or calibration sets

SET/CHANGE PIN CODE

It is optional to set a security PIN code on the scale. Once a PIN code is set, the feature is enabled and the 5 digit number will be required to gain
access to the calibration and operating mode settings.
Once the PIN code feature is enabled, it can be changed but the feature cannot be disabled without resetting the calibration values. If you
would like to disable the PIN code feature, please call Right Weigh Technical Support listed on page 2.

SET PIN CODE

With the gauge off, press and hold both the C LOW and C HIGH buttons, then press the ON/OFF button. Release all three buttons. The gauge will display “CodE”.

Press the MENU button and “00000” will display on the screen. Enter a 5 digit PIN code using the 1, 2, 3, and 4 buttons. Press the MENU button again to save the code. **If the display shows “—–”, then there is already a code set

CHANGE PIN CODE

With the gauge off, press and hold both the C LOW and C HIGH buttons, then press the ON/OFF button. Release all three buttons. The gauge will display “CodE

Press the MENU button and “—–” will display on the screen. Enter the previous PIN code. If the code entered is correct, the display will show “Good

Press the MENU button and enter the new 5-digit PIN code using the 1, 2, 3, and 4 buttons. Press the MENU button again to save the code.

OPERATE & WEIGH

Follow these steps while weighing your vehicle

1. Park on a level surface. Shift the transmission to neutral and set the parking brakes.
2. Chock the wheels to prevent unexpected vehicle movement, then release the parking and service brakes.
3. Press the ON/OFF button to turn on the Right Weigh load scale
4. Adjust the suspension or the load itself until the Right Weigh load scale displays a weight value below your legal limit.
5. Press the blue MENU button to display other axle groups or calibration sets.
6. Press the ON/OFF button to turn off the Right Weigh load scale

TROUBLESHOOTING

Erratic / Inaccurate

Weight Readings

| The vehicle is not parked on a

level surface

| Park on level concrete ground. Parking on sloped or banked surfaces will cause the vehicle weight distribution to shift between the axle groups. Additionally, if one or more of the vehicle’s wheels are in a pothole, that could result in additional pressure or torque on the suspension.
The vehicle’s brakes are on| Release the parking brakes when weighing and/or calibrating. When the

vehicle brakes are set, they could apply additional pressure or torque on the suspension air bags. This will cause the suspension to have a different air pressure than what is normally needed to hold up the given weight.

App Won’t Connect to

the Gauge

| Scale is connected to a constant

power source

| Connect the scale to a switched power source between 9 and 32 VDC (typically either the vehicle marker lights or the AUX/ABS wire). If the gauge is powered too long it can stop transmitting a Bluetooth signal and may need to be disconnected and reconnected to work again.
Scale is connected to another device| Disconnect the scale from the other device before connecting through your

device.

Phone requires re- set| To reset your phone – close the app, turn off Bluetooth, and wait 10 seconds. Then open the app and turn the Bluetooth back on. Try rescanning for the scale. If this still doesn’t work, in some cases it is necessary to restart the phone completely.
Scale Does Not Power On| Scale is not connected to a switched power source of between 9 and 32 VDC| Connect the scale to a switched power source between 9 and 32 VDC (typically either the vehicle marker lights or the AUX/ABS wire). If there is a bad connection in the circuit which causes voltage to drop below 9 volts, the scale will not power on. Test the power source with a voltmeter.
Scale is connected directly to

the battery

| Connect the scale to a switched power source between 9 and 32 VDC (typically either the vehicle marker lights or the AUX/ABS wire). The scale is active anytime it is connected to power, even if the display is off. To reset it, disconnect and reconnect to the power source, wait 10 seconds, then try again to turn the display on.
Polarity is incorrect| Correct the polarity. The red wire must be connected to positive and the black to negative.
Cannot Change

Calibration Data

| The scale has an active

user-defined security PIN code

| If the scale is protected with a PIN code, the PIN must be entered before calibration data can be changed. To understand how to reset the PIN code, see page 16. If the PIN code has been forgotten, please call Right Weigh technical support listed on page 2 for further assistance.
Gauge reading “noAir”| One or more air inputs are not receiving air (If 2 air sensors are set to Average mode and one isn’t receiving air, gauge will read noAir message)| Check that all air inputs are receiving air. Pull airline out of air fitting(s) on the back of the gauge. Follow the airline along the vehicle to the airbags to check that it hasn’t been pinched or damaged. Dump suspension and refill to ensure air bags are full.
Lift Axle being measured is in the up position| If an air input is measuring a lift axle on the vehicle and the lift axle is in the up position, the air bags will be deflated of air and the gauge will read the noAir message.

APPENDIX A

• It is very important that all wiring connections be made watertight. Connections which are not watertight can allow moisture to travel through the individual strands of the wires and make it’s way into the scale, causing permanent damage to the electronics
• Heat shrinkable splices are included in the 226-SK, 228-SK, or 229-SK Installation Kit.
• Crimp each end of the wire into the connector with        a wire crimp tool (tool not provided).
• With a heat gun or heat torch, heat the connector until it shrinks completely around each wire end. Make sure you do not burn the wire jacket
• After all connections have been made, heat shrink the entire group of splices so that it seals on the outer jacket of both cables.
