8. RESET AND DEFAULT SETTINGS

8.1

General system reset

To reset PMW press and hold the 4 buttons simultaneously for 2 Sec. This operation does not delete settings memorised by the user.
8.2 Default settings
The inverter leaves the factory with a series of pre-set parameters, which can be modified according to user requirements. Each
modification to settings is automatically saved in the memory, while the user, when required, can always restore the default conditions
(see Ripristino delle impostazioni di fabbrica par. 8.3).
8.3

Restoring default settings

To restore the default settings, switch off the inverter, wait for complete shutdown of the fans and display, then press and hold buttons
"SET" and "+" and power up the unit; only release the two buttons when the text "EE" is displayed.
In this case the default settings are restored (writing and reading on EEPROM of the default settings saved permanently on the FLASH
memory).
After setting all parameters, the inverter resumes normal operation.
After restoring default settings, all system parameters should be reconfigured (current, gain, minimum frequency, setpoint
pressure etc.) as per the initial installation procedure
