Security system
The security (password) system implemented on the control
is structured into four levels. This permits selective access
to the various parameters as dictated by the active security
level. Most function codes may be read (accessed) at level
0, the base (unsecured) level. The security level required
to change or reset each parameter is listed in Table 4-1.
The security access codes for levels 1, 2, and 3 have been
programmed into the control at the factory. These codes
may be changed by the user according to Table 4-1. Access
into the system is accomplished by entering the appropriate
security code at FC 99.
The user has the option of overriding (inhibiting) one or
more levels of security by choosing the appropriate Security
Override Code at FC 92. Choices at FC 92 are standard
security mode (no override), override level 1, override levels
2 and 1, and override levels 3, 2, and 1.
The values of the three security codes, FC 96, FC 97, and
FC 98, may be read only at level 3. If the level 3 code has
been changed and forgotten, it may be retrieved with a
compact flash card or a personal computer using ProView
NXG
software.
