Set-up / Basic Function

The structure of a concentrate supply system can be seen in the following sketches:
Figure 6-1:
The concentrate is emptied into the closed pre-filling vessel of the hydraulic part from one of two supply
containers per installed concentrate loop (C1.1, C1.2 ... C3.2). The filling level of the pre-filling vessel is
checked using a Reed contact (LS1.1, LS1.2 ... LS3.2). The filling level of the supply container can be
read off via a level indicator on the hydraulic part. When the level falls short of the Reed contact, the
system automatically switches to the remaining concentrate container of the same type. At the same time,
a container replacement request is issued. If both supply containers are empty, an error message appears
on the display.
The acid concentrate is pumped to the magnet-coupled geared pump (M1.1, M1.2 ... M3.2) via a solenoid
(Y1.1; Y1.2 ... Y3.2). And from there it is pumped via the actual pressure sensor unit (PIS1.1, PIS1.2 ...
PIS3.2) and a non-return valve (RSV1.1, RSV1.2 ... RSV3.2) to the supply loop for hemodialysis concen-
trates (acetate or lactate concentrates and acid concentrates).
Infeed to the supply loop is both at the start of the ring and at the end of the ring in the form of a pseudo
ring. Regulation of pumping capacity is carried out by comparing the actual pressure measured with the
prescribed reference value. The pump speed is changed to increase or reduce pumping capacity depend-
ing on the deviation in pressure established, in order to achieve the required loop pressure.
