Hach BioTector B3500s - New Reagents Program

▪ If the calculated % REMOVAL value is less than the
corresponding expected % level programmed in this menu,
BioTector displays FAIL as the RESULT on the Analysis Data
Screen and records into the reaction archives. If the calculated
% REMOVAL value is greater than the corresponding expected
% level programmed in this menu, BioTector displays PASS as
the RESULT on the Analysis Data Screen and records into the
reaction archives.
▪ For example, when the TOC result of the inlet stream (STREAM
1) is 3.4mgC/l at a given time during online operation, this result
falls into the “TOC < 4.0mgC/l 35%” category in this menu. If
the outlet stream (STREAM 2) result available after the
completion of the Detention Time, which is 32 minutes in this
example menu, is 2.1mgC/l, the % REMOVAL value is 38.2%.
As the 38.2% is greater than the defined 35% at this category,
this is a PASS condition, because the defined minimum %
organic removal from the inlet stream is achieved. If the outlet
stream (STREAM 2) result is 2.8mgC/l, the % REMOVAL value
is 17.6%. As the 17.6% is less than the defined 35% at this
category, this is a FAIL condition, because the defined minimum
% organic removal from the inlet stream is not achieved. In other
words, in this example and programmed category, the TOC
result of the outlet stream (STREAM 2) available at the end of
the Detention Time, must be less than 2.21mgC/l for a PASS
condition.
▪ When one of the Programmable Outputs is programmed as “DW
FAIL” in Output Devices  Programmable Outputs menu (see
section 8.3.5.2 Programmable Outputs for details), and if the %
REMOVAL is a FAIL condition as described above, the relevant
relay output signal is activated. When the % REMOVAL
becomes a PASS condition, the output signal is deactivated.
▪ The DISPLAY function of the DW Program menu is operational
in the TIC&TOC analysis type. When the ANALYSIS TYPE is
changed to TC or VOC (see section 8.3.1 Analysis Mode for
details), the display of the DW “Drinking Water” parameters are
automatically disabled by the BioTector.
8.2.5 New Reagents Program
SPAN CALIBRATION NO
▪ SPAN CALIBRATION (NO by default) defines if the Span
Calibration reactions are part of the Install New Reagents
procedure in Reagents Setup menu.
▪ If SPAN CALIBRATION is activated (YES), the standard solution
needs to be connected to the Calibration/Manual port of the
BioTector as part of the Install New Reagents procedure. See
concentrations of the TOC STANDARD defined in Span
Calibration menu (see Section 2.3.2 Span Calibration
for details).
SPAN CHECK NO
▪ SPAN CHECK (NO by default) defines if the Span Check
reactions are part of the Install New Reagents procedure in
Reagents Setup menu.
▪ Note that both SPAN CALIBRATION and SPAN CHECK
functions cannot be selected as YES simultaneously and cannot
occur together in the Install New Reagents procedure.
AUTOMATIC RE-START YES
▪ AUTOMATIC RE-START (Yes by default) defines BioTector to
return automatically online operation having completed the
Install New Reagents cycle.
