22-24 No-Flow Delay
Range: Function:
10 s* [1 - 600 s] Set the time Low Power/Low Speed must stay detected to activate signal for actions. If detection
disappears before run out of the timer, the timer will be reset.
22-26 Dry Pump Function
Option: Function:
Low Power Detection
must be Enabled (par.22-21
Low Power Detection
) and commissioned (using
either par. 22-3*,
No Flow Power Tuning
, or par.22-20
Low Power Auto Set-up
) in order to use Dry
Pump Detection.
[0] * Off
[1] Warning Messages in the Local Control Panel display (if mounted) and/or signal via a relay or a digital output.
[2] Alarm The frequency converter trips and motor stays stopped until reset.

Range: Function:
10 s* [0 - 600 s] Defines for how long the Dry Pump condition must be active before activating Warning or Alarm
3.17.2 22-3* No-Flow Power Tuning
Tuning Sequence, if not choosing Auto Set Up in par.22-20 Low Power Auto Set-up :
1. Close the main valve to stop flow
2. Run with motor until the system has reached normal operating temperature
3. Press Hand On button on the LCP and adjust speed for approx. 85% of rated speed. Note the exact speed
4. Read power consumption either by looking for actual power in the data line in the LCP or call par.16-10 Power [kW] or par.16-11 Power [hp] in
Main Menu. Note the power read out
5. Change speed to approx. 50% of rated speed. Note the exact speed
6. Read power consumption either by looking for actual power in the data line in the LCP or call par.16-10
Power [kW]
or par.16-11
Power [hp]
in
Main Menu. Note the power read
7. Program the speeds used in par.22-32
Low Speed [RPM]
, par.22-33
Low Speed [Hz]
, par.22-36
High Speed [RPM]
and par.22-37
High Speed
[Hz]
8. Program the associated power values in par.22-34 Low Speed Power [kW] , par.22-35 Low Speed Power [HP] , par.22-38 High Speed Power
[kW] and par.22-39 High Speed Power [HP]
9. Switch back by means of
Auto On
or
Off
NB!
Set par. 1-03 Torque Characteristics before tuning takes place.
22-30 No-Flow Power
Range: Function:
0.00 kW* [0.00 - 1000.00 kW] 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.
