Fig. : Filling Cycle Balance Chamber Phase 2
The right side of the balance chamber is filled
with the fluid from the dialyser by the flow pump
FPA. Simultaneously the fresh fluid in the left side
of the balance chamber is delivered into the
dialyser circuit.
The concentrate pump KP is set to a fixed speed
of 20 rpm during this test. Thereby a final
conductivity ENDLF of > 0.5 mS/cm is obtained if
concentrate is connected.
This conductivity is required to test the level
sensors in the air separator LA. If the lower level
sensor LAFSU is activated the air separator valve
VLA is opened and the balance chamber valves
are switched. Thereby FPE delivers fluid into the
dialyser circuit. VLA is only closed and switched to
normal operation if the top level sensor LAFSO
detects fluid.
