3.19.2 AP-3# No-flow Power Tuning
If auto set-up is disabled in parameter AP-20 Low Power
Auto Set-up, the tuning sequence is:
1. Close the main valve to stop flow.
2. Run with motor until the system has reached
normal operating temperature.
3. Press [Hand] and adjust speed for approximately
85% of rated speed. Note the exact speed.
4. Read power consumption either by looking for
actual power in the data line in the keypad or by
viewing 1 of the following parameters:
4a
4b
Note the power readout.
5. Change speed to approximately 50% of rated
speed. Note the exact speed.
6. Read power consumption either by looking for
actual power in the data line in the keypad or by
viewing 1 of the following parameters:

Function:
The frequency converter stops running and
activates a dry-pump alarm (alarm 93, Dry
pump). A frequency converter digital output or a
serial communication bus can communicate an
alarm to other equipment.
The frequency converter stops running and
activates a dry-pump alarm (alarm 93, Dry
pump). A frequency converter digital output or a
serial communication bus can communicate an
alarm to other equipment.
Function:
Defines for how long the dry-pump condition
must be active before activating a warning or an
alarm.
The frequency converter waits for the no-flow
delay time (parameter AP-24 No-Flow Delay) to
expire before the timer for the dry-pump delay
starts.

Function:
actual speed. If power drops to the display
value, the frequency converter considers the
condition as a no-flow situation.
Function:
Make corrections to the calculated power in
parameter AP-30 No-Flow Power.
If no-flow is detected when it should not be
detected, decrease the setting. However, if no-
flow is not detected when it should be
detected, increase the setting to above 100%.
Function:
To be used if parameter K-02 Motor Speed
Unit is set to [0] RPM (parameter not visible
if [1] Hz is selected).
Set used speed for the 50% level.
This function is used for storing values
necessary for tuning no-flow detection.
