the IP address into your browser's address field and press the Enter key.
The Login screen is shown below.
To log in, enter your user name (admin, user, or guest) and password and click
“Submit”. Once you are logged in, you can log out at any time by clicking the
“Logout” button on the navigation menu illustrated in the following section.
If you have forgotten your password; press the “Forgot password” button. The
system will ask you for a password recovery email address. If you provide the
correct email address, the system will automatically generate new passwords for all
users and send them to that address.

Page 12
3.3 Navigating the web interface
After you log in to the web site, the "Dashboard" page will be displayed. A navigation
menu will also be shown on the left allowing you to access different parts of the
system.
3.3.1 Dashboard
This is the default page after login. All users have access to this page. The dashboard
gives a general overview of the current system status. The following information is
displayed:
1. Last Reaction.
2. Reagents Status.
3. Last Faults or Warning.
4. Trend Graph
On the dashboard page, a trend graph is displayed plotting the most recent (typically
20) analysis results. In a multi-stream analyzer, the user can click on the relevant
stream number button (from 1 to 6) and the measured parameter (e.g. TOC, TP, etc.)
to view and switch between streams as illustrated in the example picture below:

Page 13
3.3.2 Reaction Graph
On this page, the user can view the current reaction graph from the analyzer. The
graph will refresh periodically.
When the analyzer is stopped an empty graph will be presented.
The drop-down menu below the reaction graph can be used to change the scale of the
graph. This could be useful when the CO2peaks are small.

Page 14
3.3.3 Remote Control
This page provides an interface which allows the user to control the analyzer directly.
The user can navigate through all software menus, start and stop the analyzer, change
settings etc.
To take control of the analyzer, press the “Connect” button. You will then be presented
with the Analysis Data Screen. Operators can use the 6 navigation buttons below the
screen to operate the BioTector in the same way they would use the physical keypad.

Page 15
Only one user can use this function at any given time. While a user is remotely
controlling the analyzer, all further remote connection attempts by other users will be
rejected. While a user has already been connected to the BioTector remotely and is
controlling it, if a second user or more users try to connect to the same BioTector,
system displays “Another web-user is controlling the system” message and it will
not allow the control of the BioTector remotely by more than one user.
It is recommended that users disconnect from the analyzer as soon as they have
finished all remote operations. If a specific user remains idle for 5 minutes while
connected, the system will automatically disconnect that user.
Control of the system locally at the BioTector, physically using the membrane keypad
and system software menus, always has operational priority. In other words, when a
user is controlling the BioTector locally, it will not be possible for any other users to
connect to the BioTector and control it remotely using the BNCU. Local control of the
BioTector overrides all BNCU remote control functions.
When a user “e.g. user A” presses any key on the analyzer, any remote control
attempt by another user “e.g. user B”who is trying to control the analyzer remotely
using the BNCU, will be rejected and disconnected until the analyzer has been idle for
60 seconds. “The system is being controlled locally” message is displayed
indicating that a user is controlling the BioTector locally, physically using the
membrane keypad.
Note: Keyboard short-cuts are available for operating the screen. See table below
summarizing these shortcuts. Please note that, depending on the browser, the user
may have to click on the virtual screen to activate this feature.

table. The user may:
Specify the number of items per page using the drop down menu.
Search for any number or string in the archive.
Type in a number or text in the “Search” input box. System automatically
displays the relevant faults containing the searched number or text.

Page 18
3.3.6 Download
On this page the user may download the selected data in the same format as can be
downloaded from the BioTector. To do this, select the items to download by clicking the
appropriate check box. The user may also specify the number of analysis results
“reaction records” to download by using the drop down selection field.
After the selection is made, click the “Download” link. Depending on the number of
items this operation may take a few seconds or a few minutes to complete. Depending
on the type of the browser used, the system will either download the data or prompt
you to save the data to a preferred location. Once the required data has been
downloaded, it can be viewed as a text file. System generates cached (pre-generated
and stored) analysis data (reaction archive/records) automatically for each month for
easy access and download.
Restriction: user and admin have access to download functionality.

Page 19
Section 4 Setup
There are three individual pages, which are Contacts, Alarms and Passwords, that
can be used to customize the behavior of the system.
Restriction: only admin has access to these pages.
4.1 Contacts
The BNCU system allows up to 5 email notification recipients. Simply enter the desired
email addresses into the form and click the Save button. A notification will be displayed
at the top of the page to indicate that data has been saved successfully.

Page 20
4.2 Alarms
The user may control how and when an alarm will be sent to the listed contacts. The
upper part of the page allows the user to setup alarm filtering. The user may disable
alarms entirely by un-ticking the Enable Alarm check box. You can also
disable/enable different levels of alarms.
Alarm levels include:
Faults
Warnings
Notifications (Notes)
The lower part of the page presents an interface where the user may configure alarms
which trigger when a particular metric has exceeded a threshold. By default, there is
no Reaction Alarm configured. The user may add a Reaction Alarm by pressing the
Add button. Once a new alarm is created, the following parameters may be specified:
Stream: The stream identification (from 1 to 6) to monitor.
Data: The measured parameters (e.g. TIC, TOC, etc.) to monitor.
Threshold: Value above which an alarm will be sent.
Alarm Message: Content of the alarm message when the measurement
exceeds the threshold.
