Functional Description

The TECTA™ B16 Detection System provides a fast, simple to use, on-site water testing solution de-signed to detect E. coli and Total Coliforms and Enterococcus. The system consists of the TECTA™ B16 Detection Instrument and the TECTAlert™ Test Cartridge. The system negates the need for lengthy and expensive off-site tests and can return negative results in 18 hours, with positive results in as little as two hours.

Figure 1-1. The TECTA™ B16 Detection System

The TECTA™ B16 Detection Instrument is a self-contained bench top device that houses 16 incubation chambers. The chambers are identified by light rings on a graphic display on the touch screen.



Figure 1-2. The TECTA™ B16 Detection Instrument

The TECTAlert™ CCA, ECA and ENA Test Cartridges are self-contained single use sample bottles and testing cartridges for combined EC/TC, Rapid EC only and Enterococcus tests, respectively. Samples are collected in the cartridge to the 100ml line and the cartridge is closed and labelled. The cartridge has a tamper evident closure and it does not need to be opened to perform the test. Each cartridge con-tains pre-measured amounts of growth media that support the enrichment of the target bacteria if pre-sent in the sample.

Figure 1-3. The TECTAlert™ CCA Test Cartridge

The cartridge is placed in one of the 16 chambers prompted by the touchscreen for incubation. As target bacteria such as E. coli or Total Coliforms or Enterococcus begin to multiply, they emit a specific enzyme that interacts with a proprietary chemical substrate in the cartridge, releasing fluorescent molecules from the substrate. The fluorescent molecules collect in the base of the cartridge where they can be moni-tored by the instrument. The concentration of fluorescent molecules allows the instrument to continu-ously monitor the level of bacteria in the cartridge.



The higher the level of bacteria in the original sample, the faster the instrument can return results. High levels of contamination can return results in as little as two hours, with lower levels taking longer. A very fast result indicates severe contamination. A negative result is returned after a period of 18 hours.

The touchscreenThe TECTA™ B16 Detection Instrument is controlled via a 7 inch resistive touchscreen. Instructions are given to the Instrument by touching the screen with a finger tip or stylus. Because the screen is resistive, it can be operated with a gloved finger. Care should be taken not to scratch the surface of the screen. An external keyboard and/or mouse can also be used.

USB portsThe TECTA™ Instrument is equipped with USB ports at the front left and rear top left of the Instrument for QWERTY keyboard and/or mouse connection as well as for copying data to a USB drive. A USB hub may be connected to either of the ports to allow the external keyboard and mouse to use the same port while leaving a spare port for data transfer.

Network PortThe TECTA™ Instrument is equipped with an RJ45 (8P8C) Ethernet socket for LAN connection. The connection is located at the rear top left above the rear USB connection. The network port is non-secure and the Instrument should only be deployed behind a firewall.

Test ModesThe TECTA™ B16 Detection System can perform two test modes. It also has a validation mode that is used to ensure the system is operating within the specified parameters.

Standard ModeThis test will incubate a sample at 35°C (EC/TC test) or at 41.5°C (rapid EC or Enterococcus tests) for up to 18 hours and will detect the presence or absence of E. coli and/or Total Coliforms (EC only for the rapid EC test, Enterococcus for the Entero test). The test indicates either a presence/absence or a quan-tity estimate, depending on instrument configuration, along with the time to result for both E. coli (for rapid EC and EC/TC tests) and Total Coliforms (for the EC/TC test) and for Enterococcus (ENA - Entero test). This test can be useful to return a quick response as the TECTA™ B16 Detection Instrument will alert the operator as soon as the target bacterium is detected. Typically, the faster the response, the more severe the contamination.

The light ring on the touchscreen will indicate red for a positive (contaminated) result, green for a neg-ative (clear) result or amber for a test in progress.

The report will give details of the test parameters selected, date and time of the test as well as any iden-tifying data entered such as the source of the sample.

Read ModeThis test will provide a present/absent result from a test sample that has been preincubated for EC/TC or EC-only tests. These samples must be preincubated at 35°C (EC/TC) or at 41.5°C (EC-only or rapid



EC) in an air incubator or similar device. However, to confirm the absence of both target bacteria, the samples must be incubated for 18 hours. The Read Test takes approximately 1 minute per sample.

WARNING!You must not test a sample in Read Mode if it has already been tested for a full incubation period within the TECTA™ Instrument. Read Mode is only for use with samples that have been incubated in a separate incubation chamber. Samples that have been incubated in the TECTA™ Instrument must not be verified in Read Mode as the results may be inaccurate.

Test TypesThe TECTA™ B16 Detection Instrument performs up to three tests at the same time.

• CCA - EC/TC test: EC detects E. coli within the sample; TC detects Total Coliforms within the sample.

• ECA - EC (Rapid EC) test: EC detects E. coli within the sample.

• ENA - Entero test: Entero detects Enterococcus with the sample.

While each quadrant (chambers 1-4, 5-8, 9-12, 13-16) must run the same temperature type of Standard mode test, different test types can be run in the instrument at the same time (Entero and Rapid EC can be run in the same mantle). Read mode tests can be run simultaneously with the other test types since the sample is not incubated during these short run tests.

The FanThe TECTA™ B16 Detection Instrument may be fitted with a fan to capture odours from samples. If it is, the symbol shown in Figure 1.4 below. The fan is operated by the operator via an icon on the touch-screen and should be used to capture odours when required. If the fan is not being used this icon can be hidden via a Service-enabled configuration option.

Figure 1-4. Fan control

The Fan Control Icon displays a red centre when the fan is inactive, green when the fan is active.



ValidationThe TECTA™ B16 Detection Instrument is supplied with a single validation cartridge used to test the calibration of the optical system. Each chamber is tested using the validation cartridge using a routine available to Admin users. Validation may be performed while other chambers are running tests. Further validation cartridges can be purchased for testing multiple chambers simultaneously.

• If the lid is left open for three minutes, all tests will be cancelled.

Summary of test options(Refer to the Functional Description for a full explanation)

Test modes:• Standard Mode will continuously monitor for the presence of target bacterium during

incubation and report a quantitative result if bacterium is found to be present.

• Read Mode will very quickly read a pre-incubated TECTAlert™ cartridge for presence or absence of E.coli and Total Coliform target bacteria.

Test types:• CCA - EC/TC: Tests for E.coli and Total Coliform bacteria separately in the same

TECTAlert™ CCA test cartridge while continuously incubating water sample at a temperature of 35 Celsius.

• ECA - EC: Will more rapidly test for E.coli only in a TECTAlert™ ECA test cartridge while continuously incubating water samples at a temperature of 41.5 Celsius.

• ENA - ENTERO: Will test for Enterococcus only in a TECTAlert™ ENA test cartridge while continuously incubating water samples at a temperature of 41.5 Celsius.

Returning a chamber to use after validation failureIf any chamber has failed validation, follow the procedure for cleaning the instrument then perform the validation procedure again. If this fails to return the chamber to operation, contact your supplier for ser-vicing.



Network TabFrom the Network Screen it is possible to configure the network settings. Contact your local network administrator for support configuring network settings.

CAUTIONThe network port is non-secure. The TECTA™ Instrument should only be deployed behind a firewall. Installation is simplest if a router with DHCP enabled is used since this can be set up in advance of instrument commissioning.

Figure 4-8. The Network Screen

The “Default Gateway” should be set to the IP address of the firewall or other machine used to connect to the Internet.

The “Network”, “Subnet Mask” and “Broadcast” address of the machine should be configured appropri-ately for the network. If the Gateway IP is 192.168.0.1 then the “Network” setting would typically be 192.168.0.1, the “Subnet Mask” would be 255.255.255.0 and the “Broadcast” address 192.168.1.255. In general the IP/DHCP drop-down should be set to DHCP.

1. Set Default Gateway to 192.168.0.1

2. Set Network (Domain Name) to 192.168.0.1

3. Set Subnet Mask to 255.255.255.0

4. Set Broadcast to 192.168.1.255

5. Set the Name Server (aka DNS Server). The name-server should be set to the value recommended by your Internet Service Provider (ISP) or your local network administrator. This can also be identi-fied by connecting a computer on the local network into a cmd prompt and typing in “ipconfig /all” as in Figure 4-9.

6. Press Save.

Email TabFrom the Email Screen it is possible to make changes to email settings. Contact your local network ad-ministrator for support configuring email.

Figure 4-10. The Email Screen

SMTP Server Address

Custom Email Configura-tion Field



Email notificationThe TECTA™ B16 Detection Instrument can be configured to send an email at the start of a test, upon detection of bacteria and at the end of a test.

• If bacteria are detected before the end of a test, an alert notification will be sent at the time of detection rather than wait until the test is completed.

• If further bacteria are detected, the instrument will send a second email, such as detection of E. coli and then Total Coliforms.

• A final completion email will be sent at the end of the test listing the full set of data listed on the Report Screen.

Note:• TECTA™ B16 supports automatic email notification of test completion in standard mode testing

only. Read mode tests will not generate an email notification.

• Only one email address can be entered. If more than one email address needs to receive notifi-cations, talk with your local administrator about an email relay configuration.

• The TEST button will send a blank email to the configured address.

• The email notification option is activated on the Preferences Screen.

The TECTA™ B16 must be connected to a network for the email capability to be accessible. See the previous section on how to configure the instrument for Network connections. Plug an Ethernet cable into the RJ45 connector at the rear left side of the instrument and connect the other end to your local network connection, preferably with a hardware firewall device like a router between the instrument and your network.

After configuring your email information as shown in Figure 4-10 press Save. Go to the Preferences Tab and ensure that the Email Notification is selected (see Figure 4-2), then press Save.

More complex e-mail settings using the Custom fieldThe e-mail configuration fields were designed to deal with the most common configurations. There are some e-mail servers that require non-default settings for things like the domain name. To support this a “Custom” field has been added to the e-mail settings page that allows users to pass any valid argument to the mailsend program used for notification e-mail. In particular, the following options are supported:

-d domain - domain name for SMTP HELO/EHLO -cc cc,cc... - "carbon copy" address(es) -bc bcc,bcc... - "blind carbon copy" address(es) +D - do not add Date header -cs character set - for text/plain attachments (default is us-ascii) -name "Full Name" - add name in the From header -v - verbose mode (this may help in debugging issues) -rt email_address - add Reply-To header -rrr email_address - request read receipts to this address

Note that care must be taken with these settings. Improper values will result in failure to send mail. Al-ways send a test e-mail before enabling!

Note:For languages other than English, special characters can cause issues with email notifications. Make sure your e-mail client has UTF-8 set as the default encoding for incoming messages. For Korean, EUC-KR is recommended.



Changing character encoding depends on the e-mail client, as follows:

•For Mozilla/Thunderbird, go to Tools->Options->Display and hit the “Advanced” button. Select “Unicode (UTF-8)” as the character encoding for Incoming Mail in the “Character Encodings” section at the bottom of the dialogue

•For Outlook, the relevant settings may be found under “Tools->Options->Mail Format->Inter-national Options (and also “Fonts” under “Mail Format”). Unfortunately, different versions of Outlook have different specific layouts, and in some cases the Options may found under “File” rather than tools. Please refer to the documentation for your version of Outlook. The important thing is to ensure UTF-8 encodings are selected, or possibly EUC-KR for Korean.

•For Google Chrome/gmail, things should “just work”, as unlike stand-alone e-mail clients, Web browsers deal with character encoding issues automatically.
