Introduction

This Special Instruction will provide instructions for installation and configuration of second-generation Product Link systems, PL121SR and PL321SR.

This Special Instruction also provides instructions on replacing the first generation of Product Link (PL151 and PL201) with the second generation of Product Link (PL121SR and PL321SR) in existing installations.

The second generation of Product Link has been installed on three categories of machines.

One category of machines is referred to as "Legacy" machines. The Legacy machines are older machines that do not have a wiring harness that accommodates Product Link already installed. Connectors are not readily available to install the PL121SR and PL321SR components. The Product Link components that are used in the Legacy machines are in the Universal Installation Group.

The second category of machines is referred to as "Product Link Ready" machines. A machine is considered to be "Product Link Ready" if the machine was assembled at the factory with a wiring harness with proper connectors to install PL121SR and PL321SR components. The "Product Link Ready" machines use the components that are in the 257-0430 PL121SR Communication Installation Gp , 273-5724 PL321SR Communication Installation Gp , or the 273-5726 PL300 Communication Installation Gp (for machines that already have a PL121SR installed).

The third category of machines that are not Caterpillar machines. These machines use the components of the 257-0430 PL121SR Communication Installation Gp .

Personal injury or death can result when voiding this certification.

Structural damage, an overturn, modification, alteration, or improper repair can impair the Rollover Protective Structure's (ROPS) protection capability thereby voiding this certification.

Do not drill holes in the ROPS. Do not weld on the ROPS unless welding is specified in the procedure. Place welds only at the locations that are specified in the procedure.

To avoid possible weakening of this ROPS, consult a Caterpillar dealer before altering this ROPS in any way. The protection offered by this ROPS will be impaired if it has been subjected to structural damage.



Consult a Caterpillar dealer to determine this structure's limitations without voiding its certification.

Installing/Mounting the PL121SR Radio

Illustration 18 shows the mounting of the PL121SR radio.


Example for mounting the PL121SR radio

Select a Location for Mounting the PL121SR Radio

Refer to Illustration 19 and Illustration 20 for appropriate mounting examples.




View of a radio that is mounted in an appropriate location


View of cables with appropriate bend radius

The location for the Radio must allow enough room to prevent sharp bends in the Radio Harness or the antenna cable. The minimum bend radius of the antenna cable is 50.8 mm (2 inch). Bending the antenna cable too tightly may result in reduced performance, signal loss, or permanent damage to the cable. Refer to Illustration 19 and Illustration 20.



Do not connect the 257-9364 Universal Harness As or the 256-6804 Control Harness As directly to the PL121SR radio. Connecting either of these harnesses directly to the PL121SR radio will disrupt communications between Cat ET and the radio.

Do not mount the PL121SR radio in an area that will expose the radio to extreme conditions of heat. Exposure to high heat may make the radio inoperable.

The preferred mounting location for the radio is inside the cab or another enclosed structure. If you are unable to place the radio inside the cab, then orient the radio with the two TNC antenna connectors downward. Refer to Illustration 18.

Mount the radio more than 500 mm (19.7 inch) from the antenna in order to minimize interference between the radio and the antenna.

Mount the radio accordingly so that the antenna cable can be connected without producing any sharp bends that may damage the cable.

The maximum torque for the radio mounting bolts is 3.5 Nm (2.6 lb ft).

The maximum torque for the TNC antenna connectors is 0.68 Nm (6 lb in).

Locate the radio so that the radio connectors are not exposed to high-pressure spray or underwater immersion. Exposure to high-pressure spray or underwater immersion may compromise the connector seals and lead to connection failure.

Do not attach the radio to the ROPS.

The radio must be installed on a flat surface.

Do not mount the radio in direct sunlight.

For more specific guidelines, refer to Special Instruction, SEHS6929, "Inspection, Maintenance, and Repair of Rollover Protective Structures (ROPS) and Attachment Installation Guidelines" as well as any other published guidelines that are specific for a machine serial number.

Mounting Instructions for the PL121SR Radio

Once the location for the radio has been chosen, refer to Illustration 18. The Illustration 18 shows the proper location and size of the holes that are needed to mount the radio.

Refer to Illustration 10 for a template of the radio.

1. Lay out the necessary hole pattern. Refer to Illustration 18.

2. Drill the holes.

3. Install the required bolts, washers, and locknuts in order to secure the radio.

4. Tighten the mounting bolts for the radio to 3.5 Nm (2.6 lb ft).

5. Refer to "Completing the Installation" for information on proper application of the Data Privacy Film and Blast Zone Warning Film.

PL321SR System Installation

Installing/Mounting the PL121SR Radio and PL300 ECM

Refer to the "Installing/Mounting the PL121SR Radio" for instructions on how to mount the PL121SR Radio.

Mounting the PL300 ECM on Legacy Machines

Note: The use of threaded bosses or welded studs is the preferred method in order to attach the ECM to a machine.

The Illustration 24 and Illustration 25 show two methods for mounting the PL300 ECM on legacy machines. The mounting hardware is included as part of the 273-5726 Communication Installation Gp (PL300 legacy). A drill template for locating the hole pattern for the ECM is included at the end of this Special Instruction.

Select a Location for the PL300 ECM

When mounting the PL300 ECM, ensure that the supplied 6 m (19.7 ft) harness will connect between the radio and the PL300 ECM.

Orient the ECM module so that the ECM connector will not be subjected to high-pressure spray or underwater immersion. Exposure to high-pressure spray or underwater immersion may compromise the connector seal and will lead to connector failure.

Do not mount the ECM module in the engine compartment or in other areas so that the ECM will be exposed to extreme heat. Exposure to extreme heat may make the ECM inoperable.

Do not mount the ECM module in an area so that the ECM could be damaged.

The ECM must be installed on a flat surface.

The desired static stiffness of the mounting points for the Product Link should be 1800N/mm (ten times mount stiffness). In no case should the stiffness at the mounting points be less than 540N/mm (three times the mount stiffness).

A boss or a welded stud is the preferred mounting hardware on a machine.

The mounting torque on the mounting bolts is 12 Nm (8.8 lb ft).

Refer to Illustration 29 for the connection of the ground strap.

Mounting Instructions for the PL300 on Legacy Machines

After a suitable location has been chosen, perform the following procedure in order to install the ECM:

1. Install the isolation mount parts on the ECM.

2. Place the ECM in the desired location for the mounting bosses, the studs, or the bolts that have been chosen.

3. Place the ground strap for the ECM on one of the mounting bolts.

4. Secure the ECM by tightening the ECM mounting bolts.

Mounting the PL300 ECM on PL151 and PL201 Ready Machines

Product Link ready machines have existing mounting locations for the PL151 or PL201. If the PL151 or PL201 is installed, the PL151 or PL201 must be removed prior to installing the PL121SR and PL300. Mount the PL300. Refer to Illustration 31. If the PL300 does not fit in the space provided for the PL151 or PL201, refer to the ""Mounting the PL300 ECM on Legacy Machines" " section in this Special Instruction.

If the machine is PL121 and PL321 ready, then the mounting space and hardware that is provided will be appropriate.
