Protecting the Keypad
5-14 Chapter 5 Diagnostic Interface-Keypad
To protect the exciter from unauthorized operation or reconfiguration, the keypad
includes two security controls, Password and Privilege Level.
The Password is a 5-digit number that protects the Password and Privilege Level
from being changed by unauthorized personnel. The default Password is 00000.
Privilege Level specifies which operational and configuration functions are disabled
in the keypad. There are three levels:
Read Only disables both the Exciter Control and the Configuration functions.
An operator can view but not edit parameters.
Operate & Read Only enables the Exciter Control function, but disables
Configuration functions. An operator can view, but not edit parameters.
Configure & Operate enables both the Exciter Control and the Configuration
functions. This is the default setting.
If you try to execute a function that is disabled in the active Privilege Level, the
keypad displays the following error message.
