Reagents Purge
ACID & BASE PURGE 50s , 3
ACID & BASE PURGE defines the operation time (50 seconds
by default) of the acid and base pumps to prime the reagents
during the Install New Reagent cycle. The reagent priming and
the subsequent reactor purge operation is repeated three times
by default.
The reagent purge is activated by START NEW REAGENT
CYCLE function in Install New Reagents menu or alternatively
by RUN REAGENTS PURGE function in Zero Calibration menu.
REACTOR ACID FILL 300p
REACTOR BASE FILL 450p
REACTOR WASH TIME 100s
The REACTOR ACID/BASE FILL time defines the quantity of
acid and base reagents injected into the reactor at the end of the
ACID & BASE PURGE phase described above.
When the acid and base reagents are injected into the reactor,
the reagents are mixed in the reactor for the duration of
REACTOR WASH time (100 seconds by default) to balance and
neutralize the reactor pH.
8.3.4.5
Pressure/Flow Test Program
TIME 08:15
BioTector performs an automatic pressure and flow test every
day at the TIME programmed (at 08:15 hours by default).
PRESSURE TEST FAULT 6.0l/h
Each time BioTector is started up and every day during online
operation at the programmed TIME above, BioTector
pressurizes the system with oxygen gas and uses its mass flow
controller to detect any gas leak in the system. If the measured
flow is less than or equal to the programmed PRESSURE TEST
FAULT flow level (6.0 l/h by default), the pressure test passes.
If the flow is greater than programmed PRESSURE TEST
FAULT setting, the pressure test fails, and BioTector generates
a “05_PRESSURE TEST FAIL” fault and stops. This fault is
logged in the fault archive. In TC – TIC systems, BioTector
generates a “07_TIC PRESSURE FAIL” fault if TIC reactor
pressure test fails.
The pressure test cycle can be disabled by setting PRESSURE
TEST FAULT setting to 0.0 l/h. When disabled, BioTector
automatically displays an “OFF” message on the screen and
logs a “29_PRESSURE TEST OFF” warning in the fault archive.
If the pressure test is skipped during the startup sequence with
the “Quick Startup” function (see Section
for details) a “28_NO PRESSURE TEST” warning is logged
in the fault archive. This warning cannot be acknowledged by the
user, it can only be acknowledged automatically by the system
the next time the pressure test is passed.
PRESSURE TEST WARN 4.0l/h
PRESSURE TEST WARNING, which is typically 30% less than
the PRESSURE TEST FAULT setting (4.0 l/h by default), gives
an advanced warning of a possible gas leak in BioTector.
The pressure warning can be disabled by setting PRESSURE
TEST WARNING to 0.0 l/h. When disabled, BioTector
automatically displays an “OFF” message on the screen.
If the flow measured during Pressure Test is less than or equal
to 6.0 l/h but greater than 4.0 l/h, BioTector generates a
“26_PRESSURE TEST WARN” and continues to run. The
warning is logged in the fault archive. In TC – TIC systems,
BioTector generates a “27_TIC PRESSURE WARN” if TIC
reactor pressure test fails.
