Note: The system will be limited to 50 keys on older machines. This limitation is due to software limitations on the Machine ECM that utilizes a version of software that does not support the larger key storage.
The ECM can store five configuration parameters that identify each electronic key. These parameters are listed below:
- "Security Type"
- "Description"
- "Access Level"
- "Expiration Date"
- "Security ID"
The parameters are not stored in the electronic key. A complete list of the configuration parameters that are available in the Caterpillar Electronic Technician (ET) are listed below:
- Add an electronic key.
- Change the information that is related to the electronic key.
- Access level
- Expiration date
- Description
- Delete an electronic key.
- "Security Bypass Times"
- Set the internal clock.
- "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 Testing and Adjusting, "Scheduled Access - Program" section addition information on item 4.
Note: A single electronic key can be used on as many machines with an MSS as desired. 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 2015A or later of the Caterpillar Electronic Technician (ET).
| Security Type | Description | Access Level | Expiration | Security ID |
| Key | Operator 1 | Master | "- - - - - " | 0:183243096 |
| Key | Operator 2 | Standard | "- - - - - " | 0:110105956 |
| Passcode | Operator 3 | Standard | "10/24/2016" | 245865321 |
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 Caterpillar ® Electronic Technician (ET). 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 the following items: 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.
Passcodes are utilized on some machine in place of electronic keys. This passcode will be a number assigned to an operator to allow authorized operation of the machine. Refer to the machine Operation and Maintenance Manual for additional information.
Note: Duplicate descriptions for the electronic keys are not advisable.
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 Machine Security System with the Caterpillar Electronic Technician (ET).
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.
The security type identifies the type of security access that is being utilized. There are currently two types of security identification.
- Key
- Passcode
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 "Dash lines". "Dash lines" indicates 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.
