Voltage control Select the voltage signal input
input range (0-10V or 2-10V).
The voltage input is linear and
controls the mix percentage of
the respective gas, where 0V (or
2V) represents 0% and 10V
represents 100%.
Buffer pressure Set the required buffer pressure.
Only applies to mixers in “MM8000” mode.
Buffer pressure Set the required pressure by which the buffer pressure must drop
hysteresis until mixer starts refilling the buffer tank.
Only applies to mixers in “MM8000” mode
Upper flow limit Even though the mixer is capable of delivering a high output, we
recommend to set the output flow a low as possible but still high
enough to maintain buffer pressure. The lower the flow the better
mixing accuracy is obtained.
Only applies to mixers in “MM8000” mode.

, Air or “No gas”.
On devices calibrated for Argon (Ar), this gas can be selected as well
Gas 1 - P Low alarm Lower pressure alarm for Gas 1
Gas 2 - Media Media connected to “GAS IN 2”
(See Gas 1 - Media)
Gas 2 - P Low alarm Lower pressure alarm for Gas 2
Gas 3 - Media Media connected to “GAS IN 3”
(See Gas 1 - Media)
Gas 3 - P Low alarm Lower pressure alarm for Gas 3
NOTE! When certain gases (including Argon) are selected, air (or other gases)
remaining in the system will appear to have a flow even when no real flow is
present. When requesting a small flow in this situation, it will not result in any flow.
Because the gas is never replaced the situation is never resolved. To resolve this
situation, the system should be flushed briefly with a flow of at least 50 l/min with
100% of the gas in question.
