SCALE INSTALLATION & ELECTRICAL CONNECTIONS

The 202-DDG-04 scale is designed to be mounted inside the vehicle cabin, it is not for outdoor use. The following steps will walk you through how to correctly mount and install the gauge.

1. CHOOSE MOUNTING LOCATION
   The gauge can be mounted in the dash panel either using an existing factory gauge hole or by creating one. If this option is unavailable or not desirable, Right Weigh has an optional bracket (202-BR) that can be purchased separately to mount the gauge. See below for a detailed list of options for mounting into the dash:
   a Use an available 21/16” (52mm) factory  agauge hole.
   b Remove and replace a factory installed drive axle air suspension pressure gauge.
   c Cut a new hole in the dash panel using a 21/16” (52mm) hole saw as shown.
   Make sure to check behind the dash panel for internal wires and components that may need to be moved to avoid damage.
   d Use Right Weigh 202-BR bracket or an aftermarket bracket to mount the gauge..

2. INSERT 202 GAUGE
   Insert the gauge into the mounting hole or bracket. Hold the gauge in a position so the display appears level on the dash panel or bracket. Note that the thickest portion of the gauge bezel indicates the bottom of the display. Screw the gauge nut onto the back of the gauge until it is tight.

3. INSTALL BEZEL STYLING COVER (OPTIONAL)
   If desired, place chrome styling cover over the front of the gauge bezel. Press until both sides snap into place.
   

4. CONNECT TO POWER AND GROUND
   Connect the wiring harness to power and ground. Be sure the RED wire is connected to a SWITCHED positive (+) power source (DO NOT CONNECT DIRECTLY TO BATTERY) and the BLACK wire to chassis ground (-). Supply voltage must be between 9 and 32 volts DC.  DO NOT connect directly to a battery or any constant power source, gauge should be connected to a switched source so that it can be disconnected from power when not in use. Most users connect the power to the ignition switch.
   Connect the wire harness to the connector on the back of the gauge.

5. DUMP AIR FROM SUSPENSION SYSTEM
   

6. INSTALL NEW STREET TEE FITTING
   Remove the suspension air line fitting from the top of one of the air bags.
   Insert a street tee fitting into the top of the air bag that matches the thread size of the vehicle suspension. Reinstall the suspension air line and fitting into the street tee. For
   more information on the parts needed for air line installation, see Appendix A.

7. INSTALL NEW 1/4” AIR LINE
   Install a new 1/4” air line and fitting into the remaining port on the tee.

8. ROUTE AIR LINE TO GAUGE
   Route the new 1/4” air line from the tee fitting assembly to the gauge. Secure air line with zip ties. Insert the air line into the push-to-connect fitting on the back of the gauge.
   

9. REPEAT STEPS 6-8 ON SECOND, THIRD, AND FOURTH HCVS OR AXLE GROUPS

10. AIR UP SUSPENSION TO CHECK FOR LEAKS

11. RE-ASSEMBLE DASH PANEL IF NEEDED

AIR SENSOR CONFIGURATION

The 202-DDG-04 gauge has four internal air pressure sensors and can be used to monitor up to four separate axle groups with one Height Control Valve (HCV) each, or a combination of of axle groups with a total of four HCVs. Follow the steps below to configure the gauge to your application:
From the Home screen, select the WRENCH icon.
From the System Setup screen, select SETTINGS.
From the Settings screen, select the RIGHT ARROW. If monitoring an axle group with four HCVs, all four air sensors must be set to Average together. If this is the case, select AVERAGE ALL. If you have more than one axle group being monitore, select USER CONFIG and then select the RIGHT ARROW to continue to the next screen.Select CONFIG INPUTS.
If monitoring an axle group with two Height Control Valves (HCVs), the two air sensors connected to that axle group must be set to Average together. For any axle groups with one HCV, the sensor for that group must be set to be Independent from the rest. To set the desired configuration, select the blue buttons between the numbers (air sensors 1, 2, 3, and 4) until each is set correctly for your application. If monitoring an axle group with two HCVs, the air lines from this group MUST be connected to two adjacent air sensors, such as sensors 1 and 2 or sensors 3 and 4, so they can be averaged together. Sensors 2 and 3 and sensors 1 and 4 CANNOT be averaged together.

CHANGING AIR SENSOR NAMES

The default settings for the gauge can be changed to make the information specific to your vehicle configuration. To change the default air sensor name, follow these steps:
From the Home screen, select the WRENCH icon.
From the System Setup screen, select SETTINGS.
From the Settings screen, select the RIGHT ARROW and then select CONFIG NAMES.
Press the first sensor or sensor group to change the name.Select the appropriate name from the list. Press the RIGHT ARROW for more options.
Repeat the process for each additional axle group.

ESTIMATED STEER

If the 202-DDG-04 load scale is used to monitor a tractor’s drive axle group, the Estimated Steer option can be enabled. Estimated Steer will not work for straight trucks or anyone who slides their fifth wheel regularly. To enable Estimated Steer, follow these steps:

CALIBRATION

The 202-DDG-04 load scale must be calibrated both empty and loaded to work properly. The scale associates the air pressure in the suspension system to the weight you enter at the time of calibration. You will need to calibrate once while the vehicle is empty, and again while the vehicle is loaded for the axle group(s) being monitored.

Only enter on-the-ground weight of axle or group being monitored. DO NOT use gross weight, tare weight, etc.
Follow calibration steps on the next page, once these are complete the gauge will be ready to use!

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. Make sure the Height Control Valve (HCV) has fully inflated the air bags. If needed, briefly dump the air from the suspension and allow the HCV to refill the system.
   

4. From the Home screen, select the WRENCH icon.

5. From the System Setup screen, select CALIBRATION.

6. From the Calibration screen select the appropriate axle group. For more options, press the RIGHT ARROW.
   

7. From the Calibration screen select EMPTY. Select YES to enter new calibration data.

8. Enter weight from scale ticket for the corresponding axle group and then press ENTER. If the value you have entered looks correct, select YES to save calibration data.

9. Repeat process for all axle groups being monitored, including steer axle if using Estimated Steer feature.

LOADED CALIBRATION POINT
Repeat “empty calibration point” steps 1-3 with the vehicle fully loaded

4. From the Home screen, select the WRENCH icon.
5. From the System Setup screen, select CALIBRATION.
6. From the Calibration screen select the appropriate axle group.
For more options, press the RIGHT ARROW.
7. From the Calibration screen select LOADED. Select YES to enter new calibration data.
8. Enter weight from scale ticket for the corresponding axle group and then press ENTER.
If the value you have entered looks correct, select YES to save calibration data.
9. Repeat process for all axle groups being monitored, including steer  axle if using Estimated Steer feature.

OPERATING & WEIGHING

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. Make sure the Height Control Valve (HCV) has fully inflated the air bags. If needed, briefly dump the air from the suspension and allow the HCV to refill the system. (This may take several minutes depending on the type of HCV.)
   

4. From the Home screen, select WEIGHT.

5. From the Summary screen, you can view the weight of the axle group(s) being monitored, the estimated steer weight (if this feature is turned on), and the total weight.

6. From the Summary screen, you can select the RIGHT ARROW to view each weight separately and the net weight.

By selecting ZERO, the net weight will reset to 0. This reading will display the net change in total weight since the last time the ZERO button was pressed.
Press the HOME button at any time to return to the Home screen.

SECURITY PIN CODE

To protect calibration data from unwanted changes, you can set a security PIN code. When a PIN is set, the user will be required to enter the PIN in order to get into the calibration screens. Follow these steps to set a PIN code:
From the Home screen, select the WRENCH icon.
From the System Setup screen, select CALIBRATION.
From the Calibration screen select the RIGHT ARROW and then select SET PIN.Enter a unique PIN code (up to 6 digits).
If a PIN code is forgotten or lost, please contact Right Weigh technical support listed on page 2 for instructions on how to reset the PIN code.

In rare cases, it might be necessary to reset the calibration data back to the original default values. To reset the calibration data to the default values, follow these steps:
From the Home screen, select the WRENCH icon.
From the System Setup screen, select CALIBRATION.
From the Calibration screen  select the RIGHT ARROWand then select RESET CAL DATA.To reset the calibration back to the default values (erase any previous calibration data) select YES.

FACTORY DEFAULT

If there is a problem with the gauge, it may be necessary to reset it completely back to factory default settings. This will remove previously set calibration data, air sensor configuration and names, PIN code, etc. To reset the gauge, follow these steps:
From the home screen, select the WRENCH icon.
From the System Setup screen, select CALIBRATION.From the Calibration screen select the RIGHT ARROW twice and then select FACTORY DEFAULTS.

To reset the gauge back to the factory default settings, select YES.

TROUBLESHOOTING

will cause the vehicle weight distribution to shift between the Se 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 air bags. This wil cause the suspension to have a different air pressure than what is noramlly needed to hold up the given weight.
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.
There is a significant air leak in the suspension system| Check air lines for leaks. Having a leak could cause the HCV to refill the suspension at regular intervals to maintain the vehicle’s ride height. lf there is a significant leak the gauge display will slowly decrease in value and then quickly increase in value when the HCV refills the suspension system.
The Height Control Valve (HCV) is malfunctioning or broken| If the HCV is not functioning correctly, the air pressure applied to the suspension system could be inconsistent and/or antic. To test for an HCV problem. acquire a weight reading from the Right Weigh gauge and write it down (refer to gauge operating instructions for proper procedure). Drive the vehicle around the block and return to the same location. Acquire a second reading from the Right Weigh gauge. If the two readings are significantly different then the HCV might be malfunctioning.
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 vehide marker lights or the AUX/ABS wire). If there is a bad connection in the circuit which causes voltage to &op 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 Will Not Calibrate Low/High| Air pressure in the system is not changing| To enter low or high cal mode, the gauge must see a measurable change in air pressure. Make sure you calibrate high when the vehicle is near the legal limit and calibrate low when the truck is empty. Also. be sure the air line is connected directly to an air bag – NOT the main air supply or brake system.
