The CO
2
gas supply should be 99.5% pure and
should not contain a siphon tube. Gas pressure
to the unit must be regulated to less than 30
psig. Failure to do so could cause tubing to
burst.
Set the Scale Low value to correspond with the minimum value of the process
output in electrical units. For 0-5V, set to 0. For 1-5V, set to 1. For 4-20mA, set
to 4.
Set the Scale High value to correspond with the maximum value of the process
output in electrical units. For 0-5V, set to 5. For 1-5V, set to 5. For 4-20mA, set
to 20.
Set the Range Low value to the minimum temperature (or humidity or CO2) that
will correspond with the Scale Low value (default is 0.0).
Set the Range High value to the maximum temperature (or humidity or CO2) that
will correspond with the Scale High value (default is 100.0).
6. If an offset (or calibration) is needed, adjust the o.CA parameter accordingly

Once all changes are made refer to Section 14 to relock the controllers.
GASG301 Built In Gas Guard System
An optional built in gas guard system is available to allow two tanks of CO2 to be
connected to an incubator requiring approximately 15 psig of gas pressure. The unit is
designed to automatically switch from the primary tank to the secondary tank when low
gas pressure of approximately 10 psig is detected on the primary tank. This allows for a
continuous supply of CO2 to an incubator after the primary tank is empty. In addition,
the user is notified of a tank empty scenario via an audible and visual alarm.
The CO
2
gas supplies must be equipped with two stage regulators to ensure that the
incoming gas to the unit is regulated to appropriate levels. The high pressure stage
should have a 0-2000 psig range, and the low pressure gauge should adjust from 0-30
psig. When connecting the gas supplies, adjust each tank output to 20-25 psig. If the
