Limit value
Fig. 72: Cable break limit value
Define limit value for cable break by turning the operating button and confirm by
pressing it.
In the next step define whether
▪ the analogue signal only changes the setpoint
▪ 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.
Signal strength below
the set limit value
is interpreted as
a cable break.
