The different operating states
Permeate production
: Production of product water. The VFEED, PHP and PASC relays are energized.
STAND-BY: Unit is waiting on request. The unit is ready for operation, all relays are off.
Flushing (to prevent deposits on the membrane surface): Factory activated in the main menu, flushing (when the unit
is switched on), before/after water production and/or cyclically after a certain number of hours. The cyclic flushing can
also be done in STANDBY mode.
Notice
: Never deactivate the flushing function! (Avoidance of microbial contamination)
The production is controlled by the two level switches in the permeate tank:
• PS
HIGH
starts the production
• PS
LOW
stops production
In the MinPressure condition, the unit starts the water production: it opens the input solenoid valve and starts the
pressure pump.
To avoid damage, a delay of 3 seconds is given after the input solenoid valve has opened.
When the MaxPressure condition is reached, the control unit goes into stand-by mode: the input solenoid valve closes
and the pressure pump stops.
In the menu it is possible to deactivate one or both level switches and to operate the system with only one or no level
switch at all. If both level switches are deactivated, the system goes into continuous production after switching on the
power supply.
When the controller is switched on, a module flush is first carried out (if activated in menu 11).
After switching on the control system and module flushing (if activated in menu 10), the control system goes into
production mode if the Min. pressure condition is underrun.
If programmed in menu 11 CLEANING the control unit starts an interval rinse during production as well as in standby
(against standstill contamination) as soon as the countdown for the rinse interval has ended. The countdown for the
rinse interval is reset at each rinse.
11.2 Operating states
After switching on the power supply, the version
number of the control software appears for a few
seconds.
Then the controller returns to the last operating state
before switching off.
WAITING
