printr-o comanda externa prin
intrarea auxiliara J5.
In acest caz PresSystem asteapta
doar comanda externa, fara sa ia in
considerare presiunea masurata. In
modul F1 este activata protectia de
supratensiune amperaj.
 F2: dispozitivul este configurat
sa Porneasca/Opreasca pompa
printr-o comanda externa prin
intrarea auxiliara J5.
In acest caz PresSystem asteapta
doar comanda externa, fara sa ia in
considerare presiunea masurata. In
modul F2 este dezactivata protectia
de supratensiune amperaj (numai la
versiunea COSφ).
 F3: utilizatorul poate porni sau
opri pompa din butonul ON/OFF.
In acest mod de operare nici o
protectie nu este activa,
dispozitivul fiind controlat in
totalitate manual (utilizatorul
porneste sau opreste pompa
manual)
 F4: dispozitivul este configurat
sa functioneze in modul
Automat, dar ajustarea presiunii
maxime apare doar daca
aceasta este mai mare decat
presiunea inregistrata la Prima
Utilizare.
 F5: dispozitivul este configurat
sa opereze in mod Automat fara
protectia Lipsa Apa. In practica,
daca presiunea masurata este
mai mica decat presiunea de
Lipsa Apa (Led Dry Running),
PresSystem nu va afisa nici o
eroare.
 F6: Dispozitivul este configurat
sa foloseasca modul de operare
tip Presostat. PresSystem
with an external command on the
auxiliary input J5.
In this case the device waits only for
the external command without
considering the measured pressure.
In F1 is enabled overcurrent
protection
 F2: the device is configured to turn
on/off the pump with an external
command on the auxiliary input J5.
In this case the device waits only for
the external command without
considering the measured pressure.
In F1 is disabled overcurrent
protection (only COSφ version)
 F3: the user can turn on/off the
pump pressing the ON/OFF button.
In this way, no protection is enabled
and the device control is totally
manual (user turns on or off the
pump)
 F4: the device is configured to
operate automatically but the
updating of the maximum pressure
occurs only if this is greater than the
stored pressure during the first
startup.
 F5: The device is configured to
operate automatically but is not
control of a dry running.
In practice, if the measured pressure
is lower than the pressure of dry
running (Led RUNNING DRY), the
device does not indicate any alarm
 F6: the device is configured to
operate like a pressure switch. The
