Low Input Pressure Alarms
At any time, if the input pressure of either gas drops to 40 PSI, a
visual and audible Low Input Pressure alarm will be activated. The

to 150 times for Oxygen and the gas supply indicators will fl ash
Green to black.
3.5. Low Input Pressure Shut Off
The device will automatically shut off should the input pressure of
either gas drop to 35 PSI. This indicates that the drive gas is now
exhausted to the point where the device will no longer function
correctly (see also the Note in 3.6).

“Failsafe” protection circuit.
Should the output pressure diff erential of the internal mixer valve
exceed 2 psi the “Fail Safe” protection circuit will activate, a
continuous alarm will sound and the device will shut off .
Note:
The shut off alarms will cease to function completely should
the O
