The algorithm used, measures the various sensitive parameters and analyses the unit status to detect the
presence and entity of the flow. For this reason, and to avoid false errors, correct parameter settings are
fundamental, and in particular:
Wait between 15 minutes and 3-4 hours, depending on the system for the algorithm to acquired all
necessary data (otherwise the quick calibration procedure can be performed, as described in section
6.5.9.1.1)
Ensure that there are no system oscillations during regulation (if this occurs, adjust parameters GP
and GI section 6.6.4
and
6.6.5)
Enter the correct rated current setting RC
Set an adequate minimum flow FT
Set the correct minimum frequency FL
Set the correct direction of rotation
WARNING: the self-adaptive mode is not allowed on multi-inverter systems.
IMPORTANT: In both operating modes the system is able to detect the lack of water by measuring the
current absorbed by the pump and comparing it with the parameter RC (see 6.5.1). If the maximum
operating frequency FS is set with a value that does not enable absorption of a value close to the current
under full load of the pump, false water failure errors (BL) may occur. In this case, remedy the situation as
follows: turn on the utilities to reach the frequency FS and at this value, check pump absorption (easily seen
on phase current parameter C1 in the User menu), then set the current value reading on RC.
6.5.9.1.1 Fast self-learning method for auto-adaptive mode
The self-learning algorithm adapts to the various systems automatically, acquiring information within a
time interval from 15 min to 3-4 hours. If the user cannot wait for this time, an alternative less time-
consuming procedure is available. The procedure enables quick initial operation, leaving the algorithm
to proceed with tuning.
Quick learning procedure:
1) Turn on the unit or, if already powered, press MODE SET + - simultaneously for 2 seconds to
generate a reset.
2) Enter the Installer menu (MODE SET -) set FI to 0 (no flow sensor) then in the same menu go
to item FT.
3) Turn on a utility and run the pump.
4) Slowly turn off the utility to reach minimum flow (utility closed) and when this value stabilises,
note the corresponding frequency.
5) Wait for 1-2 minutes after reading VF; this is indicated by shutdown of the motor.
6) Turn on a utility to achieve a frequency that is 2 – 5 [Hz] greater than the previous frequency
reading, and then wait 1-2 minutes for another shutdown.
IMPORTANT: the method is only effective if, while gradually closing the utility in point 4) the
frequency remains at a fixed value through to reading of the flow VF. It should not be considered a
valid procedure if, after closure, frequency reaches 0 [Hz]; in this case the operations from point 3
must be repeated; otherwise leave the unit to self-learn for the time interval specified above.
6.5.9.2
Operation with specific pre-defined flow sensor
This applies both to single and multiple sensors.
Use of the flow sensor enables effective measurement of the flow and the possibility of operation in special
applications.
On selection of one of the pre-defined sensors available, the diameter of the pipeline must be entered in
inches in the page FD to ensure correct flow readings (see section 6.5.10).
On selection of a pre-defined sensor, the setting of KF is disabled automatically. The parameter disabled
message is displayed by means of an icon with a padlock.
