3.11 Security
The Security Settingsmenudenespasswordaccessto
FLEX functions at the touch screen. If Password Security is
Disabled, anyone can access any function of the FLEX unit
via the touch screen with full, unrestricted access. When
Enabled, Supervisor Passcodes and Operator Passcodes
are enforced at the Home and Setup Screens. When a
user attempts to access any functions from the Home
screen (e.g. changing setpoint), the Operator Passcode
is requested via keypad interface. When a user attempts
to access any functions from the Setup screen (e.g. I/O
or network conguration), the Supervisor Passcode is
requested via keypad interface. Security Enabled is highly
recommended to prevent unauthorized or accidental
tampering of FLEX operations.
Note: If the Supervisor Passcode is set and forgotten, the
only recovery method is to perform a factory reset of the
