5.3.4 Password protection
The Expert level of the set-up menu is protected by a password, which must be entered at the beginning of the set-up menu. The
Operator level too can be protected. The Operator and Expert levels are identified by different colours in the set-up menu. Apart
from the path described in Fig. 5-6, the set-up menu can also be called from the starting display by pressing the "Up" arrow key
for a longer period.
As long as the system is being operated manually, no further password entry is required. Passwords remain valid for about
10 minutes after the last key has been pressed. After entering the password for the required level, the following display appears
for about 2 seconds:
– "Operator OK"
– "Expert OK" or
– "Incorrect password"
Operator password
When delivered, this password is not activated in the Solaris R3 control unit. By entering a 4-digit number code, all the parameters
adjustable in Operator level are protected against unauthorised access (child protection or caretaker function). The parameters
of the Operator level can only be changed with the correct Operator password or if password protection has been disabled.
Enabling and changing/reassigning the Operator password is done in the menu item: Selection 1/2\Functions\"Passw. change"
(see Fig. 5-6).
• Enter the old password in the field "present 0000" and the new password in the field "new 0000". Hereby, every digit must
be confirmed with the OK key.
• When assigning a new password, it must be entered in the "present 0000" field as well as in the "new 0000" field.
If the Operator password is enabled, the "Selection 1/2" menu item only shows "Password 0000". The Operator password is
enabled only after 10 minutes or after a restart of the Solaris R3 control unit.
Expert password
The Expert password is entered in the "Selection 1/2" menu item under "Password 0000". It provides access to all the important
system parameters required by the expert in the set-up menu (see Fig. 5-6).
