Define limit value for cable break by turning the operating button and confirm by
pressing it.
In the next step define whether
ƒ
the analogue signal only changes the setpoint
ƒ
and the pump is additionally switched off through the analogue signal.
A setpoint change can be done through analogue signals without switching on and off
the pump through the signals. In this case, "Switched off" is selected.
If the "On/off by analogue signal" function is switched on, the limit values must be
defined for the switch on/off.
Subsequently assign the MIN signal/value and MAX signal/value.

The analogue signal
changes the setpoint and
switches the pump ON

via a limit value.
The analogue signal
changes the setpoint and
switches the pump ON
or OFF
via these limit values.
