Signification Alarm
Protocol
signal
Fault pump 1 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.
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
Fault TH1
Fault TH2
Activation of the thermal control of the pump
motor. The malfunction TH1 acknowledges itself
after the motor has cooled down; TH2 has to be
acknowledged manually.
Yes Pump
TH1
TH2
Phase error A phase of the power supply has failed. Yes Dreh
Fault ATEX The ATEX mode is activated and the level is below
the switch-off point of the selected pump.
Yes Atex
Run-time alarm The runtime monitoring of the pump has been
exceeded 3 times in succession.
Yes Time
3.2 Assembly and electrical connections
All electrical connections are to be established by an authorised
professional only. Settings and adjustments on the control system
as well as the commissioning of the control system are to be
carried out by qualified persons only.
3.2.1 Mechanical fixation
The control system has to be fixed on an even surface. In order to fasten the control system, the
housing cover has to be opened.
3.2.2 Mains connection
The left cable gland is intended for the cable entry of the mains cable. The separate cables are
to be clamped into the spring terminals in the manner described below. According to the motor
which is used, a single-phase or a three-phase connection can be established.
The power supply has to be secured by an independent all-pole
fuse which can be switched off (max. 20 A).
