Signification
The internal acoustic transmitter is switched
on or off. This setting has no influence on
the potential-free alarm signal.
The alarm relay for the non-floating alarm
contact is synchronized or produces a
permanent signal.
If the pump changeover is enabled a
changeover of the pumps occurs after each
pump down.
The evaluation of the thermal contacts TH1
and TH3 (control loop) can be deactivated.
If this contact is open, the pump is shut
down and a fault is signalled. After the
contact TH1/TH3 (clipping circuit) has
cooled down and been closed again, the
pump restarts automatically.
After cooling down, the activation of the
pump in case of malfunction TH2/TH4 can
only be effected by acknowledging the
malfunction by pressing the key
This contact can not be deactivated by
means of the software. If the pump is not
equipped with thermal contacts, a bridge
has to be inserted as a substitution for TH2/
TH4.
The energization of all the 3 phases and the
proper phase sequence at the mains input
are monitored.
To be disabled for 230 V pumps.
If the ATEX mode is enabled, it is not
possible to switch on the pump if the turn-off
level is under-run. This also applies for the
HAND function and the 24h starting.
If the service mode is disabled, it is
not possible to set the parameters. The
modification mode is only possible for the
service mode itself.
Level measurement via dynamic pressure
measurement
Level measurement via external sensor
Level measurement via floating switch
By pressing the key sequence
, the zero point of
the internal converter is adjusted. The
adjustment has to be carried out while
the pilot tube is emerged (with barometric
pressure). This adjustment is to be carried
out by a service technician only.
