If any parameter data status is found invalid (e.g. from restore with different de-
vice), invalid data status parameter will be skipped and continue with update of
other parameters.
12.1.5 Password Protection
Two kinds of passwords are available, user password and manufacturer pass-
word:
User password: used to protect parameter settings from unauthorized or un-
●
intended changes.
Manufacturer password: used for service purposes ONLY.
●
Code
Name
b0.20 User password
b0.21 Manufacturer password
Both passwords always read as 0.
Possible operations with passwords are as below:
Set user password
●
The default setting of user password is '0' (inactive). Enter any integer num-
ber between 1 and 65,535.
Change user password
●
Enter the existing user password and then modify to the value of any integer
number between 1 and 65,535.
Clear user password
●
Enter the existing user password and modify to '0' to deactivate the password
protection. If the super user password is entered the user password will be
cleared directly.
When a user password is set all parameters can only be changed if the correct
password (user or manufacturer) was input by the user. Parameter b0.00 can al-
ways be changed as this just changes the view, but does not allow other param-
eters to be changed.
If the user password can't be remembered anymore or was set by accident, our
service department can help with a super user password.
User password protection does not affect frequency adjustment with Up and
Down buttons in running status or frequency saving.
After a boot process the password protection will be active if the password pro-
tection is activated.
