PROTECTED PARAMETER MODE
The Protected Parameter Mode is accessed from the
normal display mode by pressing the PAR button with
program disable active. In this mode, the operator has
access to the list of the most commonly modified controller
parameters that have been “unlocked” in the configuration
parameter lockouts module. Depending on the code
number entered in the lockout module, access to the
unprotected parameter mode and hence, the configuration
parameter modules, is possible. The controller returns to
the normal display mode if the unprotected mode and
configuration modules cannot be accessed.
