Scrolling to an Address
If you are not sure of the number of the Address you
want to view or change, or if you want to scroll to
another address, you can select an Address with the
navigation keys. Two keys (double arrows keys)
change the Address block, while two (single arrow
keys) move up and down within an Address block. As
each key is pressed, the LCD identifies the newly
selected block or address.

Changing a Setting
To change the content of a memory address, the
Address must be selected and the relay must be
placed in password mode. How you then change the
address's content depends on whether the
Address content is an entered value, an option chosen
from a menu, or an option chosen from a two-level
menu. These procedures are described in this section.
If relay configuration settings have been changed the
processor system will reset when the settings are
saved. During reset the device is not operational.
The relay stores the changed information in volatile
memory until you explicitly save it, as described in the
procedures in this section. Note that saving a setting
change may be required before the relay will allow
further parameter changes related to that setting. This
will also require a re-entry of the password.

14.3.1
Entering Password Mode
To prevent inadvertent changes to the relay
configuration or loss of recorded data, any keypad
inputs that would affect the operation of the relay must
be preceded by the entry of a password that places
the relay in password mode. You do not need to be in
password mode to examine the present settings, look
at event and fault logs, or look at measured values.
Normally the relay is in Display mode when powered
up. The display has a solid rectangle on the first line of
the front panel display that does not blink when the
relay is in Display mode. In password mode, the
display shows the solid rectangle blinking on the first
line of the display.
Note: The factory-set password is six zeros (000000)
and cannot be changed. The relay remains in
password mode until you save the settings as
discussed below.
You can enter the password before or after selecting
an address, but you must enter it before you can
change the content of the address.
To place the relay in Password mode, do the following:
1. Press the Password key. The password prompt
will appear:.
ENTER PASSWORD
2. Enter the relay's password (000000) using the
number keys from the keypad. The LCD displays
each digit entered as an @ symbol:
ENTER PASSWORD
@@@@@@
3. Press the Enter key after you complete the entry.
