Fault load
Current flow below 0,5 A. Either
no pump is connected, or a
phase is lacking.
This malfunction can be suppressed, if for the
motor current monitoring 0.0A are set in the menu
“current limitation“.
If both pump currents are set
to 0,0A, the control system is
running in the test mode. The
pumps are not deactivated. All
functions of the control system
are enabled. The motor current
is not monitored.
Yes
Last
Fault pump 1
Fault pump 2
The motor current monitoring system has detected
an exceedance of the set limit value and has shut
down the pump motor.
Yes
IP1
Fault high water
The HW-sensor reports an alarm and switches on
the pump. The HW-malfunction acknowledges itself
when the turn-on level is reached again.
Yes
HW
Fault
I<3mA
The external sensor is selected, but the current
is <3mA. There might be a disconnection, or
the sensor might be defective. The malfunction
acknowledges itself when the sensor current is
within the normal range.
Yes
I<3mA
Fault
SW
The floating switches are connecting in the wrong
sequence (e.g. the lower floating switch is open
when the upper floating switch closes).
Yes
SW
Pump 1
Fault TH1
Fault TH2
Pump 2
Fault TH3
Fault TH4
Activation of the thermal control of the pump
motor. The malfunction TH1 and TH3 acknowledge
themselves after the motor has cooled down; TH2
and TH4 have to be acknowledged manually.
Yes
Pump 1

Phase fault
A phase of the power supply has failed.
Yes

Fault
ATEX
The ATEX mode is activated and the level is below
the switch-off point of the selected pump.
Yes

Run-time alarm
The runtime monitoring of the pump has been
exceeded 3 times in succession.
