2.4 Password
2.4.1 Access to service levels by password
Depending on password (service or OEM), different parameters are visible.
"Service" parameters, as per the actuator curves and the set-point values, are password protected. The operator must logon using the "
9876
" password.
"User" level doesn't need a password.
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 then
finally 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, only 1 character is visible. When the
last character of the password is reached, the entry is to be confirmed by pressing Enter.
Display before the first password character is entered:
Enter Password
:
* * * * * * * *
The example displays when entering the third password character:
Enter Password
:

If the check of the password entered is positive, the change to the next menu level takes place. Otherwise, the display returns to the main menu level.

then press “ Enter “ twice.

functions on the first level menu: press to choose “PW Logout” then press “Enter“.
