Entry of password (PW)

It is very important to study chapter «Safety notes on settings and
parameterization»!
Before changing to the parameter settings range, a password must be entered. For that
purpose, the display shown below appears.
First, the pointer points to the first character of the line «Access without PW». Access
without PW is always available for access level «Enduser».
• If a valid password has been entered, there will be no more password prompt when
accessing this parameter setting level until the end of the legitimation period is reached,
or until legitimation is manually deactivated
• If required, access to the parameters can be deactivated on the bottom line of the main
menu before the legitimation period expires
If a password shall be entered, line «Enter password» is selected by means of
decrementing (pointer points to the first character of that line) and selected by pressing
ENTER.
Then, the pointer jumps to the first position of the password entry line. Now, through
incrementing or decrementing, a character (digit or letter) can be selected. A character
is confirmed by pressing ENTER. If a wrong entry has been made, the last character
can be edited again by pressing ESC.
The other password positions can be selected, edited and entered in a similar way.
Hence, when making an entry, there is always only one character visible.
When the last character of the password is reached, the entry is to be confirmed by
pressing ENTER.
• The passwords are linked to the access levels (Service, OEM, Siemens). This means
that the parameters available for editing are only those associated with the access
level
• When leaving the parameter setting level, a backup is offered
