3.2 Logging In and Out

To access the device you must first have completed the initial setup procedure (see

Section 2 Commissioning and Startup for details). To access the device you type

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 11

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 12

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 CO2 peaks are small.

Page 13

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.

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 17

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 18

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 19

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.

Page 20

 Normal Message: Content of the alarm message when the measurement

returns to normal.
The reaction alarm will be sent only once when the threshold is crossed.
For example a system may have one alarm configured as follows:

Stream ID: Stream 1

Data: TOCmg/l

Threshold: 3.42

When the TOCmg/l measured result exceeds the 3.42 threshold value on stream 1, an
alarm “Alarm Message” will be sent to all of the contacts. As long as the measured
results remain above the threshold value, no further alarms are sent. When the
measured result drops below the threshold value, the “Normal Message” is sent.

To make changes into an existing alarm, the alarm must be first removed using the
Remove button and a new alarm should be created using the Add button.

A notification message “Data Saved” is displayed at the bottom of the page to indicate
whether data was successfully saved or not.

Alarms will be sent by email to the contacts listed on the “Contacts” page (see section

4.1 Contacts for details). The system will also send notifications when the SD card

usage is dangerously high.

Page 21

4.3 Passwords

This page allows the admin user to change passwords for various users. The default
passwords for admin, user and guest are “admin”, “user” and “guest” respectively. To
change the passwords enter the current password for the admin user in the first text
input box and fill the other text input boxes with new passwords for admin, user and
guest. Then, click the Save button to save the changes.

The changed passwords will take effect the next time a user attempts to log in. A
notification will be displayed at the top of the page to indicate whether data was
successfully saved.

Page 22

4.4 System

Warning: This page contains advanced features. Please use with care and avoid
unnecessary modifications in this page.

4.4.1 System Information

Such information includes OS “operation system”, system uptime, IP address, SD
card usage, hardware and software version, system serial number and BNCU time
information.

4.4.2 Stream Names

This function allows the user to name the streams for the optional BioTector Master
Network Control Unit.

Page 23

4.4.3 Timezone Configuration

This section is used to set the time-zone of the network-control unit. It does not
affect the time used in the analyzer.

4.4.4 Network Configuration

This section is used to program or modify the network settings of the device during
commissioning or when it is necessary. Any unnecessary changes in this section
should be avoided.

Changing the IP address will cause the page to become unresponsive. System
commissioning and startup procedures described in Section 2 Commissioning and

Startup may need to be followed to regain access to the BNCU.

Page 24

4.4.5 S.M.T.P. Server

This section is used to configure the device to use your S.M.T.P. Server. This
allows the device to send emails. The device has been tested with a number of
S.M.T.P. Servers but is not compatible with every server. It is known to work with
Google's S.M.T.P. Servers such as gmail.

When a local S.M.T.P. Server is used, you may need to specify a DNS server for
the Network Configuration (see section 4.4.4 Network Configuration for
details) for the device to send e-mails successfully.

You can also click the Test button and enter an email address to test your
configuration.

4.4.6 Security

This section contains the security options available for you. It is intended to be
used by those with advanced Networking/Security knowledge only.

Note:

 The BNCU ships with a certificate from the BioTector Certificate Authority

(C.A.)

 The BioTector C.A. is based on a self-signed certificate

 This means that the C.A. and consequently the certificates issued will not be

trusted by default. This leaves you with four options:

1. Avoid using HTTPS.

2. Add an exception for each certificate.

3. Add the BioTector C.A. certificate to your company's active directory.
If it does not work with Firefox, use Google Chrome. This will make
BioTector issued certificates to be trusted.

Page 25

4. Provide your own certificate and private key for the device to use.

The security page contains the following options:

 Make HTTPS Mandatory

▪ All connections to port 80 are redirected to port 443
▪ This forces all users to use a secure connection

 Use BioTector Certificates

▪ This will restore the system to using the factory shipped certificates

and private key

 Get C.A. Cert.

▪ This option allows you to download the current Certificate Authority

certificate

 Get Device Cert.

▪ This option allows you to download the current device certificate

 Upload Certificate

▪ This form allows you to upload your own certificate, private key and

C.A. certificate to the device

Page 26

4.4.7 System Update

This section allows you to update the software of the BNCU when necessary.
Manual Update requires a software update package, which can be obtained from

the distributor or the manufacturer.

Page 27

4.4.8 System Commands

This section is for sending system commands to the device such as reboot,
shutdown etc.

Create Diagnostic Report function generates a diagnostics report for analysis.
When the report is created, a link is generated, which can be used to download the
report.

To ensure data consistency, it is recommended that you power off the BNCU
through the web interface (system page) using the Shutdown function. Cutting off
the power supply directly from the BNCU may cause data inconsistency or loss.

Reboot function can be used in the event of a communication problem with the
BioTector. For testing or during any software upgrade procedures, Fast Reboot
can be used as the system will not wait at the default IP address for 100 seconds.

Convert to BNCU-Master/Slave function allows the user to convert a Master unit
to a Slave or vice versa.

4.4.9 Database Commands

The Clear Reaction Archive and Clear Fault Archive functions can be used to
clear the archives when necessary.

The Database reset function will reset all passwords, languages, clear reaction
and faults archives etc.

Page 28

4.4.10 Factory Reset

The Reset function sets all BNCU settings such as passwords, network settings
etc. back to factory defaults and clears all archives.

4.4.11 Web Access

Yaler software provides web access to the BNCU if the BNCU is firewall protected or it
is using a 3G connection. When necessary, a Relay Domain and Relay Server address
can be obtained from www.yaler.net and submitted in this menu to function.

Page 29

Section 5 Master Network Control Unit

The BioTector Master Network Control Unit (BMNCU) is an optional desktop unit,
connected to the network, which communicates with all other available network control
units (slaves) installed into the BioTectors.

The Master Network Control Unit page gives a complete overview of all your analyzers
on the network, allowing you to monitor them with ease at a centralized location.

The commissioning and startup procedures, described for BioTector Network Control
Unit (BNCU) in “Section 2 Commissioning and Startup” in this manual (see Section 2

Commissioning and Startup for details), can be applied for the BioTector Master

Network Control Unit (BMNCU) as well.

1. Analyzers Page
This page shows the Name, Results and system status of each of the configured

BNCUs.

Page 30

When logged in as an admin user, analyzers containing the BNCU options can be
added or removed from the displayed table using the Add function under the Add
Analyzer section with the relevant IP address and port number, which is 80 by
default. Analyzer name is optional. The preferred analysis results can be displayed
in above table by ticking the relevant parameters in the Display Configuration
section.

Page 31

When an analyzer is monitored/controlled through the master network control unit,
the user can return back to the analyzers page using the “BNCU MASTER” return
button located at the top right corner of the webpage.

Alarms configured in each individual BNCU are automatically retrieved by the
BMNCU which flags the value in red as shown in below example.

2. System Page
This is the similar with the System page of BNCU discussed in section 4.4

System above. Some options in the BNCU system page may not be applicable

to the BMNCU. Passwords, discussed in section 4.3 Passwords above, can be
set up for BMNCU in the BMNCU System page.

Page 32

Section 6 Troubleshooting

6.1 BNCU Not Communicating

 Check and confirm that 24V DC power is supplied to the unit looking at

system drawings supplied with the BioTector user manual.

 Remove the Motherboard cover and confirm that the LED located on the

right top corner of the “ETH” port on the BNCU is flashing.

 Follow procedures described in Section 2 Commissioning and Startup in

this manual.

6.2 Unknown IP Address

 Every time the BioTector and thus BNCU is powered up, the booting process

of BNCU takes approximately 45 seconds. The unit always uses its default
IP address for 100 seconds duration after the completion of the booting
process.

 When there is a communication problem due to an IP address issue, to

recover the unit, simply follow the commissioning and startup procedures
described in Section 2 Commissioning and Startup only this time log in
within approximately 150 seconds of applying power to the BioTector and to
the BNCU as described in section 2.2 Initial Configuration of the

Network Control Unit.

 Above procedure will prevent the unit switching over to the incorrect IP

Address settings. If this procedure does not help, contact your local
distributor or the manufacturer.

6.3 “Another web-user is controlling the system” Message

 When “Another web-user is controlling the system” message is displayed, it

will not be possible to control the BioTector using the BNCU, because a user
has already been connected to the BioTector remotely and is controlling it.

 When a user is connected to the BioTector, it is not possible for a second

user or more users to connect to the BioTector. Please try again later.

Page 33

6.4 “The system is being controlled locally” Message

 When “The system is being controlled locally” message is displayed, it will

not be possible to control the BioTector remotely using the BNCU, because
a user is already at the BioTector and is controlling the BioTector locally
physically using the membrane keypad.

 When a user is controlling the BioTector locally, this overrides remote control

functions therefore it will not be possible for any user to connect to the
BioTector and control it remotely. Please try again later.

6.5 Reaction Archive Not Up To Date

 When the reaction results are not up to date or not updating on the BNCU,

login to the BNCU with the username “admin”. The default admin password
for the BNCU is “admin” unless it is changed on site or during the
commissioning.

 Scroll down the System page. Under the Database Commands section,

select “Clear Reaction Archive” and select “OK”. Select “Clear Fault Archive”

and select “OK”.

 The communication will be restored when the next analysis result is

available.

6.6 Security Warnings

 When “Security Certificate” or “Untrusted Connection” warnings are

displayed while trying to connect to the BNCU, select “Proceed” or select

“Add permanent exception” to establish communication.

Page 34

6.7 “Database Error” Message

In the event of a database communication problem, the user may be unable to login or
recover the webpage. In such instances, the system may display the “Database Error”
or “ERROR: Could not connect to database” warnings as in the example above.

Follow the procedures in the order described below:

1. Try Again. This function redirects the user to the login page.

2. Create Diagnostic Report. This function allows the user to generate a

diagnostic report for analysis.

3. Clear Logfiles. This function allows the user to erase all system logfiles,
which could be the cause of “Database Error”.

4. Fast Reboot. This function allows the user to reboot the relevant network
control unit.

Page 35

5. Database Reset. This function resets the database.

6. Fast Reboot. This function allows the user to reboot the relevant network

control unit.

7. Restore from backup. This function restores the archives using a
