HIGH
The system operating pressure can be controlled by
means of a pressure switch between the high pressure
pump and the RO modules. If a maximum pressure set
on the pressure switch is reached during production
(e.g. due to an overly restricted concentrate valve), the
system can be stopped.

11.6.10 Upstream softening
system INFIL
If the upstream softening system is e.g. equipped with
an automatic backwashing device and has a potential-
free switching con-tact to show the backwashing, then
the control system can shut down the WL-ROC system
for the duration of the filter backwashing and put it on
hold.
It is also possible to connect an upstream 1-col-umn
softening system to the control so that the RO unit goes
into standby mode for the duration of the regeneration.
