3.1.6 Warnings and notices of malfunction
The following warnings and notices of malfunction can be indicated on the display. In the fault
protocol, the data will be recorded :
2nd line on
display
Fault load
This malfunction can be suppressed, if for the
motor current monitoring 0.0A are set in the menu
"current limitation".
Fault pump 1 The motor current monitoring system has detected
an exceedance of the set limit value and has shut
Fault pump 2
down the pump motor.
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.
Fault The external sensor is selected, but the current
is <3mA. There might be a disconnection, or
I<3mA
the sensor might be defective. The malfunction
acknowledges itself when the sensor current is
within the normal range.
Fault The floating switches are connecting in the wrong
sequence (e.g. the lower floating switch is open
SW
when the upper floating switch closes).
Pump 1
Activation of the thermal control of the pump
Fault TH1 motor. The malfunction TH1 and TH3 acknowledge
Fault TH2 themselves after the motor has cooled down; TH2
and TH4 have to be acknowledged manually.
Pump 2
Fault TH3
Fault TH4
Phase fault A phase of the power supply has failed.
Fault The ATEX mode is activated and the level is below
the switch-off point of the selected pump.
ATEX
Run-time alarm The runtime monitoring of the pump has been
exceeded 3 times in succession.

Signification
Current flow below 0,5 A. Either
no pump is connected, or a
phase is lacking.
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.
