Flow monitor
V-40 – 55 V-65 – 150 X E B
D-23 D-45 D-65 – 200 X E B
The flow monitor (F1) monitors the water supply on the water feed pump
(M1), and thus prevents the impeller from running dry. The flow monitor
must detect a flow eight seconds after switching the water feed pump on,
otherwise the pump switches off with the error message No demin
water.
This process can only be repeated twice, after waiting
30 seconds each time!
In this way, the operator has the opportunity of opening a tap
which may have been closed.
The pump can then only be restarted by switching the main
switch on the device off and then back on again.
3.8.2 Steam generation in the sterilisation chamber (E and B devices)
Position and function
The heating elements in the sterilisation chamber are used for steam
generation. The design of the elements can be found in the device-specific
operating manual.
After the program is started, the demineralised water level in the
sterilisation chamber is regulated for heating according to the WaterTime
operating mode.
The sterilisation chamber is heated with a regulated pressure. The phase
is switched to the sterilisation phase after the sterilisation temperature and
pressure is reached at the end of the heating phase.
Electrodes
The low electrode (E2) protects the heating (H1) and the chamber
electrode (E3) regulates the water level in the sterilisation chamber.
