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.
