Components that are monitored by the Implement ECM to control the operation of the Cat® Production Measurement application

The Cat^® Production Measurement application is an electronic system that provides an accurate weight of the material that is loaded by a wheel loader. This application is a distributive system using the following:

• Implement system hardware

• Implement ECM information

• Communication Gateway ECM for data storage

• Machine display module

Reference: For the diagnostic code and event code procedures for components that are used in this application, refer to the Troubleshooting manuals for the applicable machine. To access the manuals, go to SIS web (https://sis.cat.com). Enter the serial number prefix for the machine into the "Serial Number or Prefix" field on the web page. The serial number prefixes for the applicable machines are listed on the cover of this manual.

Cat^® Production Measurement Components

Machine Display Module Interface

This application utilizes the machine display module to interface with operators and technicians.

Reference: For details about the machine display module, refer to Systems Operation, UENR5155, "950M/962M/966M/972M/980M/982M INFORMATION MONITORING SYSTEM".

Store Button

(1) Store button

The store button provides one switch to ground input to the Implement ECM. The same common ECM ground circuit is used for the button that is used for the other Implement ECM connected switches and sensors.

When the store button is pressed, the ECM will detect that the button input circuit is grounded. The Implement ECM response will be dependent on the system mode that is currently active.

The Implement ECM does not monitor the store button for diagnostics.

Sensors

This application is a distributive system that utilizes the following components of the Implement control system:

• Lift cylinder head end pressure sensor

• Lift cylinder rod end pressure sensor

• Lift linkage position sensor

• Tilt linkage position sensor

• Hydraulic oil temperature sensor
