Fig. : Flow Diagram Level Regulation Module
There are two level regulation modules with different assemblies, i.e. for
machines with a single blood pump and with a double blood pump. The level
regulation module and the level regulation pump
LRP
are assembled on the
inside of the rear door. The level regulation module and
LRP
have the following
functions;
•
Setting of the level in all blood side chambers (3/2 way solenoid valves

,
VPV
,
VPE
,
VPU
,
VPD
and diaphragm pump
LRP
)
•
Monitoring of the blood side pressures (pressure sensors

•
Test of the blood side pressure sensors in preparation (3/2 way solenoid
valve
