Password Function (
P
)
By means of the password function, the station can be protected against accidental or
unauthorized parameter changes. The password can be entered in the form of a number
between 0 and 999. The value 0 (display: 000) indicates that the password function is dis
-
abled. After a sequence of digits has been entered and confirmed by pressing the ENTER
key, three dashes (- - -) are displayed. The station is password-protected as of this point
in time. All settings can still be viewed.
To disable the password function, the three dashes (- - -) are displayed again in the cor
-
responding menu. The password must now be entered and confirmed with the ENTER
key. If the password is correct, then the three zeros (000) are again displayed; the dashes
remain displayed in the event of an error.
The password is the same for all programs, e.g. it is independent of the preset program.
A program choice (manual / Tool selector) is also possible with an activated password.
If the user wants to change a parameter at a password protected station, the station
must be unblocked by the password. The display changes immediately to enter password
by the (+)/(-) keys. Then the password can be entered with the (+)/(-) keys and can be con
-
firmed by ENTER key. The station checks the password and returns to the parameter.
If no password is adjusted by the user, the station resets automatically to the actual
value display after 8 seconds.
If the password was not entered correctly, the parameter cannot be changed. The pass
-
word check is indicated again via (+)/(-) keys. The check can be stopped and changed to
the next parameter by the ENTER key.
If the password was entered correctly, the param
-
eter can be adjusted via the (+)/(-) keys. The input can be ended and changed to the next
parameter with the ENTER key. The unblocking of the station still remains for 30 seconds
after the last key activity so that for the following parameter changes the password
does not have to be entered again. If no function key is pressed within 30 seconds, the
unblocking expires and the password must be entered again at the next parameter set.
If the password protection should be active again after an input before expiry of 30
seconds, the station must be turned off for a short time or the existing password has to
be changed.
