• Field #32: Password Management
PASSWORD LEVEL 1
code=**** status=OFF
This field allows status, ON/OFF and the level, 1 or 2 to be changed as well as the password itself.
When a Level, or Status, or Password is changed, it is always required to confirm the correct
password for that level: For example, we will change the Level 1 status to On by positioning on the
word OFF, then rotating knob to change from OFF to ON. The following request for password is
displayed:
ENTER PASSWORD
....
After the correct password has been entered the screen will change to the following:
CONFIRM PASSWORD 1
P001 N
In the example, the password, “P001”, is displayed in the lower display followed by the letter “N”
indicating the status “ON”. If the example were reversed and we changed the status from ON to OFF,
the steps and confirmation display would be the same except for the letters “FF” to indicate OFF:”
CONFIRM PASSWORD 1
P001 FF
With password enabled, any attempt to access the equipment will cause the request of a correct
password. Failure to do so or an error in entering the password will cause a time-out process during
which no command will be recognized by the equipment. The timeout starts after the last action of
the jog knob plus the default timeout of 3 minutes. After which it will be possible to retry access and
input a valid password.
INVALID PASSWORD!
....
If an incorrect password is entered, it will be necessary to wait for the end of the resulting time-out
before another possibility is granted. The following error message is generated, and the display
remains frozen, preventing further operations until the time-out. Subsequently, it is possible to exit
the Screen with “Escape” and then possibly try again.
