Password Protection
When in force, the password prevents unauthorised parameter
modification by making all parameters “read-only”.
If you attempt to modify a password protected parameter, it will cause
“PASSWORD ??” to flash on the display.
The password protection is activated/deactivated using the ENTER PASSWORD and CHANGE
PASSWORD parameters.
Activated: ENTER PASSWORD and CHANGE PASSWORD values are different
Deactivated: ENTER PASSWORD and CHANGE PASSWORD values are the same
To Activate Password Protection
By default, the password feature is disabled, i.e. both parameters have the same value, 0x0000.
1. Set a new password (anything other than the default value of 0x0000) in the CHANGE
PASSWORD parameter, for example 0x0002.
2. The ENTER PASSWORD parameter will now automatically display the new password
(e.g. 0x0002). Enter any number other than the password in the ENTER PASSWORD
parameter.
