Entering a password

4-4
Note:
If the protection is operated from a personal computer using the DIGSI communication
software, the test addresses are identified by a four-digit number. This number will be
stated in brackets in the section below.
For most operational functions, the input of a password is necessary. The "password"
is a predefined key sequence which must be entered before any inputs can be made.
This applies for all entries via operator keypad or user interface which concern the
functions of the 7SS601 measuring system, such as:
• system design parameters for operating language, interface and device configura-
tion,
• marshalling of command relays, alarms, binary inputs, LED indications,
• setting of operational parameters (thresholds, functions),
• starting of test procedures.
In order to indicate authorized operation and to prevent unintended alterations, the
password must be entered before any alteration can be performed.
When a menu item is selected which requires password input, press one of the keys
+ or – to inform the system of the intended alteration. The display then shows the
prompt "&: " which indicates that the password is required. The password itself con-
sists of the key sequence – + –.
The entered characters do not appear in the display; instead only a symbol "#" ap-
pears. After confirmation of the correct input with E the display responds with
"&: 2.B". Press the key E again.
If the password is not correct, the display shows "&: :521*". Pressing the keys + or –
allows another attempt at password entry.
By pressing the enter key E one more time the menu item is displayed again, this time
with an underscore to indicate that alterations can now be made. Use the keys + or –
in order to change the presented text or numerical values. A flashing cursor indicates
that the system operates now in alteration mode, starting with the first alteration and
ending after confirmation of the altered item with the enter key E. The alteration mode
is equally ended when the setting menu is left or after an internal waiting time.
Subsection 3.3.1 describes how to navigate in the operation tree.
