5.4.1 Access Levels & Codes
Access levels can be used to prevent changes
to parameters by unauthorised personnel.
The X-STREAM menu system supports four
prioritized access levels, which can be acti-
vated and deactivated separately, and should
be supplied with their own access codes.
Level four has the highest priority and is
used for factory settings — only qualied
EMERSON service personnel have access
to this level.
Level three gives access to system admin
parameters, e.g. for conguring data acqui-
sition systems communication.
Level two covers the expert settings, e.g.
basic settings for calibrations and measure-
ments.
Level one is the user level and includes
• parameters which should be set by trained
personnel only.
• functions, not to be started by any person
(e.g. start calibrations).
All menus not assigned to one of these levels
are not editable or of minor relevance.
Within this manual, the descriptions of the
menus and procedures also indicate, which
level the menus are assigned. These assign-
ments cannot be changed.
Access codes for levels 1 to 3 can be de-
ned, activated and deactivated by the client.
The analyzer is delivered with the following
settings:
Level Access code Status
1 00000001 Off
2 00000002 Off
3 00000003 Off
Notes!
If a low level is locked (status On), all higher
levels will also be locked.
If a high level is unlocked (status Off, or code
entered when requested), automatically all
lower levels will also be unlocked.
For above reasons, it is always possible to
enter a higher code than requested, to gain
access to a menu (e.g. if access code 1 is re-
quested, you may also enter access code 2).
