Function:
Low Power Detection
must be Enabled (par. 22-21) and commissioned (using either par. 22-3*,
Tuning Auto Set-Up
, or par. 22-20 ) in order to use Dry Pump Detection.
Messages in the Local Control Panel display (if mounted) and/or signal via a relay or a digital output.
The frequency converter trips and motor stays stopped until reset.
Function:
Defines for how long the Dry Pump condition must be active before activating Warning or Alarm
Function:
Read out of calculated No Flow power at actual speed. If power drops to the display value the frequency converter
will consider the condition as a No Flow situation.
Function:
Make corrections to the calculated power at No Flow Detection (see par. 22-30).
If No Flow is detected the setting should be increased to above 100%. If however No Flow is not detected the
setting should be decreased.
Function:
Motor Speed Unit
To be used if par. 0-02,
Set used speed for the 50% level.
This function is used for storing values needed to tune No Flow Detection.
