Technical data
S-ORC (Sensitive Oxygen Ratio Controller)
Device outlets
At a flow of approx. 200 mL
Set the N
2
O concentration in the fresh gas
between 0 and 75 %.
In case of insufficient O
2
S-ORC limits the N
2
O concentration in the fresh
gas so that the O
2
concentration does not drop
below 23 Vol%.
N
2
O flow control valve is open and at the same
time the O
2
flow control valve is closed or set at
less than 0.2 L/min.
S-ORC prevents N
2
O flow.
In case of N
2
O failure
O
2
can continue to be supplied. No alarm.
Serial interfaces
COM 1
Only connect to devices that meet the require-
ments of IEC 60950-1 for ungrounded SELV
circuits and the requirements of IEC 60601-1
(as of the 2nd edition) for exposed secondary
circuits with maximum 24 Vdc nominal voltage.
