User Access Limitations
To change some of the configuration settings of an ECO unit it will be necessary to
have access at an appropriate level. When the user attempts to access a variable
or function that requires approved access, Xtralis VSC will display the logon dialog
shown in figure 25.

There are three levels of access available for the user to select
User – This is the minimal access level that allows key functions to be
performed by authorized personnel on a day to day operational basis, such
as.
o
Resetting latched alarms
o
Retrieving event logs
o
Flow Normalisation
Administrator - This is the normal access level for important functions to
be performed only by sufficiently trained and experienced service
personnel on an operational level above that of the user, such as.
o
Modification of the Detector Configuration
o

Distributor - This is the advanced access level that allows full access to

commissioning, such as.

To gain access at the selected level the user is required to enter the specified PIN
for that level of access. These PINs should be held by the site authority and only
distributed to personnel that are sufficiently trained for that level of access. The site
authority can obtain the PINs from the local Xtralis Sales representative or
distributor.
