is stored in the electronic key. The ECM will then compare this ID to the list of authorized keys. The
following table tells the operator the status for starting the machine. The status light is located near the key
start switch.
Table 1
Green light The machine will start.
Red light The key is not authorized.
Note: MSS will not shut down the machine after the machine has started.
Security Management
The MSS has the capability to allow you to program the system to automatically activate at different time
periods with different keys. The MSS can also be programmed to reject a specific electronic key after a
selected date and time. When you turn the key to the OFF position and the MSS is active, you have a 30
second interval in order to restart the machine with an unauthorized key. Also if the machine stalls, there is
a 30 second interval for restarting the machine. This 30 second interval is counted from the time of turning
the key to the OFF position.
Note: Know your machine's settings because the use of an electronic key is no guarantee that the machine
can be restarted.
An expiration date can be set for each electronic key that is contained in the list of keys for the machine.
The key will no longer start the machine when the internal clock in the security system passes the
expiration date. Each entry in the list of keys can have a different expiration date.
Spare keys are available from your dealer. Before a key can operate the machine, the MSS must be set to
accept that particular key. Contact your Caterpillar dealer for information on additional features of the MSS.
