Password Entry

SMCS - 4490

There are three levels of password protection on the EMCP 3 control panel. All of the adjustable parameters
are associated with a specific level of security that is required in order to make an adjustment to the

arameter.

The passwords only affect changing parameters from the EMCP 3 control panel. Changing parameters with
the Caterpillar service tool does not require passwords.

The level of password protection that is required for each setpoint is identified on the parameter setpoint
entry screen. A security level identification number "1", "2", or "3" next to a padlock symbol is displayed on
the parameter setpoint entry screen. Level 3 security is used for the most secure setpoints and Level 1
security is used for the least secure setpoints.

If the EMCP 3 is currently at the required level of protection when viewing a parameter, then the padlock
will not appear.

If a parameter is displayed with a padlock, but there is no security level identification number associated
with it, then the parameter cannot be changed from the EMCP 3 display.

Level 1 and Level 2 passwords are disabled when shipped from the factory. If desired, Level 1 and Level 2

asswords can be user defined on initial startup of the EMCP 3.
