MSS3s Machine Security System Caterpillar


Key Information

Usage:

120G 11W
You may configure the machine security system to recognize 255 authorized keys. This list contains those keys that will disarm the machine security system. The user adds keys to this list.

The ECM can store five configuration parameters that identify each electronic key. These parameters are listed below:

  • Description

  • Access level

  • Expiration date

  • ID1

  • ID2

  • Key Type

The parameters are not stored in the electronic key. A complete list of the configuration parameters that are available in the Cat ® Electronic Technician (Cat ® ET) are listed below:

  1. Add an electronic key.

  2. Change the following information that is related to the electronic key.

    1. Access level

    2. Expiration date

    3. Description

  3. Delete an electronic key.

  4. Security bypass times

  5. Set the internal clock.

  6. Fleet configuration

Note: Refer to the Testing and Adjusting, "Key - Program" section for additional information on items 2.a, 2.b,2.c,3, 5, and 6. Refer to the Systems Operation, "System Disarm Feature" section for additional information on item 4.

Note: A single electronic key can be used on as many machines with an MSS as desired. A separate key for every machine is not necessary. Key strategies will vary depending on machine fleet usage. The following parameters can be different on each machine: Description, Access Level and Expiration Date. The ID will be the same on all the machines.

Note: The features of the MSS are supported in version 2015B or later of the Cat® ET service tool.

Table 1
Security Type  Description  Access Level  Expiration  Security ID 
Key  Operator 1  Master  "_ _ _ _ _"  0:183243096 
Key  Operator 2  Standard  "_ _ _ _ _"  0:110105956 

Security Type

The security type identifies the type of security access that is being utilized. There are currently two types of security identification.

  • Key

Security ID

The ID that is stored in the electronic key is a 16-digit number that is displayed as two 8-digit numbers in the Cat ET service tool. This field is known as "Security ID". When the numbers are combined, the complete ID number is formed. The ECM uses this ID to associate a key to the set of parameters in the list of keys. Entries in the list may have the same information for Description, Access Level, and Expiration Date. You may choose a description of 11 characters or less for each key in the list of keys. There can be multiple entries in the list with the same description. Create a description so that the key describes either the owner of the key or the function of the user.

Note: Do not make duplicate descriptions for the electronic keys.

Access Level

You may assign one of two access levels to a key in the list of keys. The levels are either "Standard" or "Master". Both access levels allow the key to disarm the system for operation. The master access level also gives the user the ability to modify the settings of the MSS with the Cat ® ET service tool.

The standard access level is for normal operation of the machine. The master access level should be restricted to those persons that need to modify the settings of the machine security system.

Expiration Date

An expiration date may be assigned to any key in the list of keys. This expiration date is defined in 6 hour intervals on a given date. The third entry in Table 1 contains an expiration date. For all of the other keys in Table 1, the column with the expiration date is filled with "Dashed lines". "Dashed lines" indicate that those entries do not have an expiration date. The machine security system has an internal clock. Once the internal clock has passed the expiration date for a key, that key will no longer disarm the system. However, the entry will not be deleted from the list of keys. A new expiration date can be set, or the feature can be disabled. A possible use for the expiration date is used with a rental contract.

Note: If the machine is running when the expiration date and time are reached, the machine will continue to run. When the machine is shut down and the 30 second grace period has timed out, the machine will not be allowed to restart.
