FILTER NX KIT 2440011 - Caterpillar

The Maximum Payload Speed Manager will activate whenever the weight of the payload exceeds the overload limit. The actions of the Maximum Payload Speed Manager will occur regardless of the location of the truck. The speed of the truck is limited when the weight of the payload exceeds the overload limit regardless of the location of the truck. The speed of the truck is limited until the payload is dumped and the weight of the payload is cleared. The speed of the truck will return to normal at the beginning of the next payload cycle.The weight of the payload is calculated as the truck is shifted into second gear. This calculation is referred to as Second Gear Re-Weigh. The weight of the payload is used to determine if the speed of the truck is safe.When the Maximum Payload Speed Manager determines that the truck is overloaded, the following actions are initiated:
The shift range of the transmission is limited to second gear.
High idle of the engine is limited to 1750 rpm.
The point for automatic retarding is reduced to 1750 rpm. Note: The settings for limited performance are not adjustable.Example of the Operation of the Maximum Payload Speed Manager
The Project Manager has determined that a 20% overload for a 793F truck is the correct limit for operating conditions at a mine. The 793F has a target payload of 240 tons. The Project Manager would set the parameters of Maximum Payload Speed Manager to the values that are listed below:Target Payload Setting - 240 tonsPayload Overload Limit Setting - 120%With these settings, the Maximum Payload Speed Manager will function in the manner that is listed below:
The payload loading lamps will display a signal to load through 240 tons.
The overload warnings will occur above 264 tons.
The engine speed will be limited to 1750 rpm in second gear above 288 tons.Configuring the Maximum Payload Speed Manager
The Maximum Payload Speed Manager requires the user to input weight information for the payload that is specific to the model of the truck. This information is used to trigger the events that are listed below:
Overload speed limiting
Overload events
Overload warningsTarget Payload
The "target payload" is the correct payload weight for the truck model. The target setting for the weight of the payload determines the correct operation for the payload monitoring systems of the truck. The setting for the "target payload" is adjustable from zero to the target weight of the truck. The target weight is 100% of the weight of payload that is calculated from the Gross Vehicle Weight of the truck. The setting for the "target payload" is recorded in the onboard memory of the VIMS Application ECM. The "target payload setting" can be input via the Advisor or Caterpillar ET. The service operation of Payload Configuration is used to set this value. Refer to the Systems Operation, "Payload System - Configure" section in this manual for instructions on entering this information into the system. Setting the Payload "Overload Limit"
The overload limit is the percentage of overload that
