is not necessary to recalibrate unless the suspension characteristics change. For details see “Troubleshooting”. For best accuracy, calibrate and weigh on a level surface. To calibrate or weigh the hydraulic lift, you must lift the front of the trailer slightly to pressurize the hydraulic system. Briefly release the PTO pressure to stabilize the hydraulic pressure.
I.A. Scale Display Overview Before using your Air-Weigh Tractor Scale, it is necessary to calibrate it. Before starting that process it’s a good idea to become familiar with the Scale Display. Below is a definition of the use of each button. The function and use of these buttons remain the same throughout all operations of the scale.
When selecting this calibration method, you MUST enter empty weights when the vehicle is empty and heavy weights when the vehicle is loaded heavy. Failing to do so will result in inaccurate weight readings. Alternatively, for those with hydraulic lift systems or suspensions on several vehicles, it may be more convenient to enter the RATIO and OFFSET calibration data directly, if these are known.
II.B. CALIBRATING THE TRACTOR SCALE OVERVIEW For Manual Calibration, the EMPTY and HEAVY axle weights must be entered by the user. When calibrating using this method, the EMPTY weights must be entered while the vehicle is empty, and the HEAVY weights must be entered while the vehicle is fully loaded.
II.D.1. CALIBRATING EMPTY WEIGHTS Press <ESC> one or more times until the Main Menu appears, with VIEW WEIGHTS blinking. Select PRINT,SETUP, leading to next menu. Select SYSTEM SETUP, leading to next menu. Select CALIBRATION, leading to next menu. Select MANUAL CALIBRATION, leading to next menu. Select EMPTY WEIGHT, leading to next menu.
II.D.2. CALIBRATING HEAVY WEIGHTS Press <ESC> one or more times until the Main Menu appears, with VIEW WEIGHTS blinking. Select PRINT,SETUP, leading to next menu. Select SYSTEM SETUP, leading to next menu. Select CALIBRATION, leading to next menu. Select MANUAL CALIBRATION, leading to next menu. Select HEAVY WEIGHT, leading to next menu.
II.E. Calibration by Direct Entry of RATIO and OFFSET To use this method, you must first obtain the RATIO and OFFSET values from another LoadMaxx Tractor Scale on a tractor with an identical hydraulic lift system, which already has been correctly calibrated. Then you can directly enter these values into the Tractor Scale you wish to calibrate.
On all Weight Displays, when a weight is changing, it flashes rapidly until it stabilizes. On all Weight Displays, if a particular axle (or GVW or Net) is over the alarm or warning weight, causing an alarm, a bell icon flashes rapidly between the axle name (or GVW or Net) and its weight.
Note: You can turn off the How-To-Weigh instructions temporarily, until the next time you turn the truck off and on, by pushing either of the up/down arrows < > when the instructions are visible. IV.C. Creating a PIN When the trailer scale PIN is set to 0, the operator will not need to enter a PIN to access the PROGRAM menu functions.
deactivation, by up to sixty seconds. These delays can prove useful in moderating alarm responses to weight oscillations, such as those occurring during travel. For details, see Product Application Note Installing and Programming Overweight Alarms, P/N 903-0122-000. To deactivate and reset an active warning or alarm weight alarm, simply press the Enter button <ENTER>...
(See Section IV.C for PIN setup instructions) The bottom line gives the state of the alarm feature, “(Now ON)” or “(Now OFF).” Select TURN ON/OFF to change this state to its opposite. NOTE: Remember, to deactivate and reset an active warning or alarm weight, simply press the Enter button <ENTER>...
Press the <> buttons to select the desired time period. Press ENTER. This backlight will automatically dim to the “sleep mode” after the selected operation time period. To turn on the backlight, press any button. IV.G.

VI. MENU OPERATIONS AND DEFINITIONS Press the <ESC> button one or more times to reach the Main Menu. Use the <> and <> buttons to scroll to new selections. Refer to the Quick Reference Menu Directory above for the entire menu structure. WEIGHTS DISPLAYS See Section IV.A.
SCALE TYPE See the SCALE TYPE MENU subsection, below. DISPLY SETUP MENU WEIGHT SETUP MENU LBS / KGS Changes the weight display and data entry modes to pounds or kilograms. Changing this selection will also automatically convert any calibration values previously entered to the new unit of measure. 2 OR 3 LINES Causes the Weight Displays to appear in large or normal characters.
When either DATA STREAM or OBM STREAM is selected, menu changes occur. In the first level menu screen, PRINT, SETUP will change to SETUP. The second level PRINT MENU screen is no longer an option choice. MORE OPTIONS Provides access to CAN bus options and inclinometer control. CAN PROTOCOL Used to change the databus protocol between J1939 (the default) and CANopen.
DIAGNOSTICS: ALARM WEIGHTS MENU ALRM WEIGHTS Shows the programmed warning and alarm weights for each axle group, GVW and Net. Values are shown on a different display for each axle group (or GVW or Net). Use the up/down arrows <> to scroll between the axle groups.
VII. SYSTEM TROUBLE SHOOTING The Air-Weigh LoadMaxx Tractor Scale system is extremely self- sufficient. To operate correctly, power and ground are the only tractor electrical connections needed. Ensure all connectors (male/female) make a good connection and at least 9.5 volts is entering the system. When troubleshooting, initially check for power at the connecting plugs.
VII.A. INCORRECT WEIGHT READINGS If both empty and heavy weights are always off by the same amount, see the subsection ADJUST WEIGHTS in the CALIBRATION section, above. If weights are otherwise incorrect, including 0 (zero) or unstable, ensure that the sensor is connected to the Truck ComLink or Trailer Scale correctly.
VIII. MAINTENANCE Scale Display: The Air-Weigh electronic scale display should be maintenance-free under normal operation. Keep the scale in a protected environment and treat as any electronic component. Gently use a clean, soft cloth, slightly damp with water, to wipe away dust from the display.
