Introduction

This Special Instruction provides information for installation of the 230-5824 Kit . The operation of the Machine Security System is covered in the Systems Operation, RENR2462, "Machine Security System (MSS)". Refer to that manual for more information.

Do not perform any procedure that is outlined in this publication, or order any parts until you understand this information.

Note: Before you install the Machine Security System on a machine, check for other electronic control modules on the machine. Machines that are equipped with other electronic control modules must NOT use the Machine Security System to disable the "MAIN POWER" of the machine. This will prevent the Machine Security System from disabling the other electronic control modules on the machine in the event of a failure of the Machine Security System.

Required Tools

The following tools will be required to install the Machine Security System. The list below contains the recommended Caterpillar service tools.

Required Reference Material

• The Electrical System Schematic for the machine

Note: You can use the Electrical System Schematic to locate the machine harness connectors that are used when you install the Machine Security System.

Setting The Time And The Date

It is necessary to set the correct time and the date for the Machine Security System. Use the following procedure in order to set the time and the date.

Note: Changing the clock requires a "Master Access Level" key or a factory password. When using a "Master Access Level" key, you must ensure that the MSS is not in the 30 second grace period before inserting the key. To determine if MSS is in the 30 second grace period, view the "MSS Status" LED. When the 30 second grace period is active, the "MSS Status" LED will be illuminated GREEN with the key switch in the OFF position.

1. Connect the Cat ET to the service connector via the communication adapter.

2. Place the "Master Access Level" key into the key start switch and turn the key to the ON position.

3. Start the Cat ET.

Final Assembly

Follow operating procedures to add additional keys and configure the system.

1. Install the 7K-1181 Cable Straps in order to secure the retrofit harness to the machine harness. Check for pinch points and clearance from moving parts.

2. Assemble the instrument panel. Replace the covers for the machine.

Troubleshooting

The machine fails to start

Indicator light does not turn on

Verify that all connections are tight.

Check the indicator light.

Indicator light remains red

The indicator is red for five seconds after attempting to start the machine. This indicates one of the following problems:

• The key in the key start switch is not authorized for that machine. Refer to Service Manual, RENR2462, "Machine Security System (MSS)", "Key - Program".

• The exciter coil is not working properly. Check the resistance of the wiring for the exciter coil.

Indicator light becomes green but the engine will not start

The indicator light displays a green light for 30 seconds after you attempt to start the machine. This indicates that the Machine Security System has recognized a valid key for the machine. Ensure that all of the standard starting requirements for the machine have been met. Examples of the starting requirements are listed below:

• Interlocks in the operator seat

• Hydraulic interlocks

• The machine is in the correct gear

• Fuel level

• CAT data link is functioning correctly

Once you have verified that all of the starting requirements have been met for the machine, then check the wiring on the output circuits of the ECM for the MSS.
