Zeus Function Description
system is supplied with an O2 safety flow adjustable between 0.4 and
12 L/min. As an option, a 0 to 10L/min regulated O2 outlet for an O2 flowme-
ter is installed.
4.2.2 Feed-in of compressed
gases with reserve gas
cylinders As an option, it is also possible to connect a maximum of 2 reserve gas cylin-
ders.
The following function description is based on the example of O2, and is iden-
tical for N2O.
O2 flows out of the reserve gas cylinder from the cylinder connection through
the filter (23) to the pressure sensor (24). The pressure sensor signal is pro-
cessed in the CS Block PCB (see also function description for
CS Block
PCB ). The compressed gas flows on to the pressure reducer (25) and is
reduced to an output pressure of 5.5 bar. The non-return valve (26) prevents
compressed gas from flowing out of the connected CS line via a cylinder con-
nection which may be open.
4.2.3 CS Block PCB The CS Block PCB combines a processor system for pressure sensor signals
and a CAN interface on a PCB (
Figure 10 ).

The cylinder pressure reducer of the AIR reserve gas cylinder feeds
directly into the CS AIR connection in place of the CS. The O2 and
N2O reserve gas cylinders have a separate cylinder feed-in!
