|
Accidental engine starting can cause injury or death to personnel working on the equipment. To avoid accidental engine starting, disconnect the battery cable from the negative (−) battery terminal. Completely tape all metal surfaces of the disconnected battery cable end in order to prevent contact with other metal surfaces which could activate the engine electrical system. Place a Do Not Operate tag at the Start/Stop switch location to inform personnel that the equipment is being worked on. |
Prepare the Machine
- If the machine is portable, then move the machine to a smooth, level surface that will support the weight of the machine.
- Turn off the machine with the engine switch to the OFF position.
- Use proper Lock out and Tag out procedures. Attach a "Do Not Operate" warning tag to the machine start switch or the controls before you perform any service to the machine. These warning tags Special Instruction, SEHS7332 are available from your Caterpillar dealer.
Applicability
The Fluid Property Sensor is offered as an aftermarket attachment for use on all diesel fueled, off-highway engines, both Caterpillar and competitive brands, providing a fleet solution for equipment owners.
Choosing the correct Fluid Property Sensor is important. For most applications, the Non-Isolated Sensor will be used. The Isolated Sensor will be used in Marine applications only.
Electrical Requirements
This sensor is designed to operate on 12 or 24 volts DC, negative ground. Current draw of the control package is less than 2.0 amps. External solenoids or other loads driven by the control and connection of a Caterpillar Electronic Technician (ET) communications adapter will add to the current draw.
Note: 464-7820 Electrical Installation Gp must be used when the Fluid Property Sensor is used in all applications.
Remote Monitoring Requirements
Remote monitoring requires that a telematics system, such as Product Link, be installed on the machine or equipment to transmit the data off board. The Fluid Property Sensor does not include any required hardware to install a data monitoring and recording device.
Features
The Fluid Property Sensor supports J1939 protocols for communication with a monitoring and recording device.
The configuration parameters are already programmed into the ECM. When connected, CAT ET will display Engine Oil Temperature, Viscosity, Density, and Dielectric properties.
Installation of Product Link or VIMS
Inorder to collect Engine Lubrication Oil data using the installed Fluid Property Sensor kit, there must be a data monitoring and recording device, such as Product Link, installed on the machine or equipment. The Fluid Property Sensor kit does not include any required installation instructions or hardware to mount a data monitoring and recording device.

Additional Parts Needed for Installation
Fluid Property Sensor Mounting Bracket
A mounting bracket must be fabricated to support the Fluid Property Sensor. Since the kit can be used on a large range of engines in both stationary and machine applications, no universal mounting bracket design is possible. A bracket must be field fabricated to allow mounting of the sensor to a structural component of the machine. Leave room for electrical connection and room at each end for Engine Lubricating Oil line connections.
Fittings and Adapters
Due to the large range of engines that this system may be used on, a list of all Engine Lubrication Oil line fittings, sizes, styles, and adapters are not possible. As a starting point, the inlet and outlet of the sensor adapter is a 37 degree Flare for 1" oil lines. This must be adapted to the correct size oil line tubing required for each engine. It is likely that the supply and return fuel lines will be of different sizes. It is recommended that the oil line tubing be new and in good condition. The tubing MUST be clean inside. Any small particles that are carried from the inlet hose through the transducer from the system and dislodge the particles. If hoses are equipped with O-ring fittings, the O-rings must be new.
Wiring Diagram
Note: During Installation, it is important to protect wiring in key locations. Key locations are any area where the wiring could be nicked or cut and come in contact with the chassis. Avoid installation practices where there could be excessive flexing, chafing, or cutting of the wiring.
