Signification
The turn-on delay of the pump only functions
after a restart of the control system (e.g.
after a power failure). With "normal" switch
operation via the levels N1 and N2, this
setting is not relevant.
This function may be used to avoid the
simultaneous switch-on of several pumping
station after mains failure.
After having reached the turn-off level, the
pump is still running for the adjusted amount
of time.
If the adjusted value is reached, the
monitoring system of the pump motor current
effectuates the shutdown of the pump,
accompanied by a notice of malfunction.
The malfunction has to be acknowledged
manually by pressing the key
Attention : If the nominal current is
adjusted to 0 A no monitoring of the motor's
charging rate occurs !
The pump P1 is briefly started if no request
occurs by the switch-on level within 24
hours.
If the ATEX mode is enabled, the 24h
starting is only taking place if the turn-off
level is exceeded.
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.
The evaluation of the thermal contacts TH1
(control loop) can be deactivated. If this
contact is open, the pump is shut down
and an error is signalled. After the contact
TH1 (control loop) has cooled down and
been closed again, the pump restarts
automatically.
After cooling down, the activation of the
pump in case of malfunction TH2 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.
