6.6.17 SF: Starting frequency
Available only for type M/M inverters in sizes 11 and 14 A.
SF is the frequency set for the pump's turn on, in a set time ST (see section 6.6.18. The default value corresponds to
the pump's rated frequency, but it can be changed pressing "+" and "-"; it can be changed in a range between Fn and
Fn-50%. When FL value is higher than Fn-50%, SF will be limited to the FL minimum frequency. For example when
Fn = 50Hz, SF can be set between 50 and 25Hz. When Fn = 50Hz and FL = 30 Hz, SF can be set between 50 and
30Hz.
6.6.18 ST: Starting time
Available only for type M/M inverters in sizes 11 and 14 A.
ST is the period of time in which SF frequency is supplied (see section 6.6.17), before the frequency is automatically
managed by PI parameter. The ST default value is 1 sec. and it its normally the best for most of the pumps. In any
case, ST can be changed between 0 and 3 secs. When Ft = 0 secs, frequency will be immediately managed by PI and
the pump will turn on at the rated frequency.
6.6.19 RF: Fault and warning log reset
To clear the fault and warning log, press and hold the buttons + and – simultaneously for at least 2 seconds. The
number of faults present in the log (max. 64) are summarised below the RF symbol.
The log can be viewed from the MONITOR menu on the FF page.
6.6.20 PW: Change password
The device has a password-enabled protection system. If a password is set, the parameters of the device will be
accessible and visible but it will not be possible to change them.
The only parameters that allow the password to be changed independently of the setting are: SP, P1, P2, P3, RP, FP,
LA, CT.
When a password is used (value of PW different from 0) all modifications are blocked and "XXXX" is displayed on the
page PW. If the password is set it allows to navigate through all the pages, but at any attempt to edit a parameter a
pop-up appears, asking you to type in the password. When the correct password is typed in the parameters are
unlocked and can be edited for 10' after the last key is pressed.
If you want to cancel the password timer, just go to page PW and hold down + and – together for 2".
When the correct password is typed in a padlock is shown opening, while if the wrong password is given a flashing
padlock appears.
After resetting the factory values the password is set back at "0". Each change of the password takes effect when
Mode or Set is pressed and each subsequent change of a parameter implies typing in the new password again (e.g.
the installer makes all the settings with the default PW value = 0 and lastly sets the PW so as to be sure that the
machine is already protected without any further action).
If the password is lost there are 2 possibilities for editing the parameters of the device:
