Autoweigh
The TPMS will automatically weigh a load in the truck body immediately before a load is dumped. The load will be weighed and recorded in memory if the following conditions are met:
The body up indicator is off.
The hoist control has been in the FLOAT position for 10 seconds or more before the hoist control is moved to the RAISE position.A load will be recorded each time these conditions are met.Payload Operator Display
Illustration 1 g01032563
Payload Indicator (1) - This liquid crystal display (LCD) indicates the weight of the material that is located in the truck. The weight is displayed in kilograms or pounds. Refer to Service Manual, RENR4725, "Truck Payload Measurement System" for information on changing the units.A fault code will be displayed if a malfunction is detected in the system. If a malfunction is indicated, a fault code such as "ChX TRA.FAULT" will be displayed. The fault code informs the operator that a machine system requires attention. The problem should be reported in order to allow maintenance to take appropriate action.Load Indicator Lights

Illustration 3 g03167176
External Load Indicator Lights (2) - External load indicator lights (2) are the external red lights and the external green lights that are located on each side of the truck.These indicator lights inform the operator of the loader and the operator of the truck when the load has reached target payload weight. External lights (2) are only active during loading.During loading the green lights will turn on when the preset lower target weight has been reached or exceeded. The green light signals the loader operator to continue loading at a reduced rate.The red lights will turn on when the preset upper target weight has been reached or exceeded. The loader operator should stop loading when the red lights remain on.Refer to Service Manual, RENR4725, "Truck Payload Measurement System" for information on changing the values for the lower target weight and the upper target weight.TPMS Switches

Typical Example
TPMS Switch (3) - Push down on the bottom half of the switch in order to activate the TPMS. Push down on the top half of the switch in order to deactivate the TPMS. Auxiliary Switch (4) - If required, depress the auxiliary switch to record the current load.Cycle Data
Throughout the truck load cycle, several conditions are monitored. The data that is collected during each load cycle is stored into the memory. Later, the data may be downloaded through the ET service port by using a laptop computer. For more information, refer to Service Manual, RENR4725, "Truck Payload Measurement System".The memory can contain the data that is collected for 1000 load cycles.Download load cycle data before the memory limits are reached. If the memory limits are exceeded, some of the memory space will be cleared automatically. The oldest load cycle will be deleted in order to clear the memory space. Deleting the oldest cycle allows new load cycle data to be stored. Data will be retained for the most recent 1000 load cycles.Clear Totals
