Optional Equipment - Section 6 OM6004 Page 6-2 Haulpak Payload Meter OPERATION AND FUNCTIONS When power is applied to the Payload Meter, a self test function turns on all LED segments and the deck mounted lights. The LED segments remain lit for 3 seconds. Then the time of day is displayed for 7 seconds. When the 10 second self test is complete, the deck mounted lights turn off and normal display logic begins. NOTE: For best results, the truck should be positioned on a level surface with rear tires not positioned on large rocks or berms while being loaded. DISPLAY LOGIC The Payload Meter displays payload weight, the time of day, or 0 according to the following logic. 1.
Time of day is displayed if the wheel brake lock is off. 2. Payload weight is displayed when the wheel brake lock is on and the payload is greater than 5% of rated payload. 3. 0 is displayed: a. For one second after the wheel brake lock is switched off or b. The wheel brake lock is on and the payload is less than 5% of rated payload or c. The body is up. METRIC / SHORT TON SELECTION The payload meter can display either metric tons or short tons. The displayed payload weight can be changed to metric tons by installing an EB0865 jumper wire in the plug socket provided in the payload meter harness near the number 21 pin payload meter connector. To display and store short tons - no jumper.
To display and store metric tons - install jumper.
