15.1.4 Gas Control with 4 TMFCs
If your system is equipped with four TMFCs, you can select either O2 Enrich
or 3Gas as the
Operating Mode
(
see Figure 54 below
) for fermentation.
Figure 54: Controller Setup Screen (4 TMFCs)
The gas process loops you will find in the
SUMMARY
screen are labeled
AirFlo (1), O2Flo (2), and CO2Flo (4). There is also a third loop called
Gs3Flo (3), for the addition of a gas of your choosing. The loops’ numbers,
1-4, correspond to the gas connections on the cabinet (
see Figure 1a
).
#
NOTE:
Any loop name ending in Flo represents a certain gas (e.g., AirFlo, O2Flo,
etc.) with a dedicated TMFC. If the gas loop name does not end with “Flo”,
it represents the presence of a gas solenoid valve rather than a TMFC.
The Gs3Flo (3) gauge screen (
see Figure 55 on the following page
) allows you
to set parameters for the TMFC that controls this gas.
With 4 TMFCs,
you can select
O2 Enrich or 3Gas
as the Operating
Mode.
