6.6.15 RF: Fault and warning log reset
To clear the fault and warning log, press and hold the b 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.
6.6.16 PW: Password settings
The inverter is equipped with a password protection system. If a password is set, the inverter parameters will be accessible and
readable, but no modifications are admitted.
When the password (PW) is "0" all parameters are unlocked and can be modified.
When a password is used (PW value other than 0) all modifications are blocked and "XXXX" is displayed on the PW page.
If a password is set, user navigation is admitted in all pages, but on any attempt to make modifications to a parameter, a pop-up
window is displayed, requesting entry of the password. The pop-up window enables the user to exit the window or enter the password
for access.
When the correct password is entered, the parameters remain unlocked and modifiable for 10'.
To cancel the password timer, enter the PW page and press + and - at the same time for 2 seconds.
On entry of the correct password, an opened padlock symbol appears, while on entry of the incorrect password will display a flashing
padlock symbol.
If the incorrect password is entered 10 times consecutively, the same padlock error symbol appears with inverted colours, to indicate
that no password will now be accepted until the unit is switched off and on again. After the factory settings are restored, the password
is reset to "0".
Any change to the password is applied when Mode or Set is pressed, and any subsequent change to a parameter requires entry of
the new password (e.g. the installer makes all settings with the default PW value = 0, and the last thing he/she does is to set the PW
so that the machine is totally safe without any further actions).
If a password is lost, there are two options to modify the inverter parameters:
