Hach BioTector B7000 User Manual page 73

Using the Commissioning menus, follow below procedures:
In Reaction Time menu, program the INTERVAL time depending on the required sample
analysis frequency.
In Sample Pump menu, confirm that the Sample Pump FORWARD and REVERSE times are
correct. In order to test the Sample Pump forward and reverse times, go to Process Test,
Sample Pump Test menu and select the PUMP FORWARD TEST and PUMP REVERSE
TEST. Sample Pump times can be set individually for each stream in Sample Pump menu.
Adjust the Sample Pump FORWARD times and confirm that sample liquid coming from each
stream bypasses the system and drips into the drain pipe on the side of the BioTector.
If the SAMPLER is used, then the default sampler time is 100s. This default time must not be
changed unless the time programmed in the PLC of the sampler is also changed. See
sampler user manual for details.
In Stream Program menu, set the required multi-stream parameters (stream operation
sequence, number of reactions to run at each stream and operation range for each stream).
Automatic range change function should not be used in multi-stream systems.
In COD/BOD program menu, if COD and/or BOD parameter is required, program DISPLAY
with the required parameter. Install the necessary STREAM and TOC, TN, NO
for each stream. If required, the factors for each stream can be obtained following the
procedures described in information sheet "I030. TOC to COD or BOD Correlation Method".
In Reagents Monitor menu, if required, activate/deactivate the reagent monitoring function,
program the reagent volumes and set the relevant reagent warnings.
In Autocal Program menu, if required, program the automatic zero and span calibration
cycles.
In 4-20ma Program menu, set the required parameter for each stream and set the full scale
of each 4-20mA channel. In order to program the correct full scale of each 4-20mA channel,
see System Range Data screen and Stream Program menu.
In Relay Program menu, if installed, set the required ALARM levels for each stream. Set the
required idle state and the fault conditions of the COMMON FAULT relay.
In Data Program menu, if required, program the relevant configuration parameters for the
specific output device communication port.
Program the concentration(s) of the standard solution in the Span Calibration menu (see
Section 2.2 Calibration Menu). The concentration of the calibration standard used must be
typically greater than 50% of the full scale of the RANGE the calibration is carried out. In
order to see BioTector calibrated ranges, see System Range Data screen.
standard solution, see procedures described in Section 6 Calibration Standards or information sheet
"R009. Standard Solutions for BioTector Multi-component Analyzer".)
Connect the standard solution to the MANUAL/CALIBRATION port. If these ports are not
available, use the SAMPLE 1 port. Avoid the manual purging of the calibration, manual grab
sample and sample lines using the Simulate menu, because the system reactor may get
contaminated during the automatic sample valve and pump synchronization process. To
purge these lines, it is recommended to use PUMP FORWARD TEST and PUMP REVERSE
TEST functions in the Sample Pump Test menu. It is recommended that the standard solution
is located at the same height as the sample pump. Run the Span Calibration cycle using the
RUN SPAN CALIBRATION function in Span Calibration menu. A minimum of five complete
analysis cycles is recommended for the span calibration.
