5.3 Password

pRack pR300 manages three levels of password:
•
User
•
Maintenance
•
Manufacturer
Each level includes the same rights as the lower levels, that is, the
Manufacturer can access all the screens and parameters, the Maintenance
can access the screens and parameters available in the Maintenance and
User levels, while the User can only access the screens and parameters
available in the User level.
Note: All levels display the main screens and the other information
screens.
When pressing a prompt is shown to enter the password, which
remains active for 5 minutes after the last button is pressed.
The menu screens show their own password level using an icon at the
top right: 1 line: user, 2 lines: maintenance, 3 lines: manufacturer.
The password level can be changed from menu branch F.d. at any time.
The password can also be changed in the corresponding menu branch.

5.4 Description menu

Main menu – Function tree
The following general rules apply to the user interface:
•
The parameters are grouped by functions and where necessary
repeated, for example the status of the compressors inputs/outputs is
visible in both branch C.a.a (Compressors), and in branch B.a (Inputs/
Outputs)
•
The parameters are grouped by type of access, fi rst User then
Maintenance then Manufacturer
•
The most frequently used parameters are indicated fi rst, the less
frequently used are last
•
Each user only sees the parameters and menu items that are available
for that access level
•
Only the screens and parameters corresponding to the selected
system confi guration are visible, that is, corresponding to the devices
confi gured. The exception to this rule involves the screens relating to
functions that can be enabled/disabled (e.g. set point compensation),
which are visible even when disabled.
Regardless of the current screen displayed, pressing the
