The flow volume is measured using a pulse encoder in the water appa‐
ratus. The flow volume is monitored. If the limit value (adjustable in the
parameter menu) is undershot, a warning is first output. If the flow volume
is not increased above this limit value, then the system switches to fault
mode and the preparation process is interrupted.
If flow measurement does not function, the system can be
operated with a preset value. You can find the setting for this
in the service menu.
9.11 Redilution
This function is used by the control to monitor a downstream redilution
unit. For this, the running signal of the transfer pump is signalled via a
potential-free contact. Additionally, the control has an input, which moni‐
tors a limit switch n the water supply line. If the limit switch is not active
‘5
s’
after switching on of the pump, a fault message appears on the touch
panel and the fault indicating relay triggers.
