Front Panel Program Disable
There are several ways to limit the programming of parameters from the
front panel buttons. The settings of the parameters in the Lockout Module, the
code number entered, and the state and/or function programmed f or the User
Input (Terminal #7) affect front panel access.
It is possible to have the program disable function on versions with the
User Input, even if the User Input is not programmed for program disable
(PLOC), by the use of a code number. Versions that do not have the User Input
are dedicated to the program disable function.
The following charts describe the possible program disable settings
depending on your model.
