8.5 The Password Menu
The DF-310E Process Oxygen Analyzer may include optional password protection which can be
used to limit access to the Control Menu, the Set-Up Menu, and the Diagnostics Menu.
Note: When the Password entry is selected from the Main Menu, a DISABLING ALARMS
message appears which notifies the user that the alarms have been temporarily disabled. The
alarm overlay messages will not show in the display. Relays will remain in the alarm state
that immediately preceded the Disabling Alarms message.
The password operates on two levels, a Master Password to establish overall control of the
system, and an Operator Password to allow partial access to the system. If the selected level
requires a password, the display will present a password prompt. The password menu is
displayed in Figure 46.
Figure 46: Password Menu
The two-letter codes adjacent to the Set-Up, Control and Diags entries in the display are used to
indicate the level of password that is required to access the Set-Up, Controls or Diagnostics
menus. There are three possible settings for each entry:
MA (Master) - Indicates that the master password must be used to access the menu.
OP (Operator) - Indicates that the operator password or master password can be used to
access the menu.
NU (Not Used) - Indicates that no password is required to access the menu.
