To change the password for Access Level 1 to BIKE enter the following:
The relay responds by setting the password, pulsing closed the ALARM relay, and transmit-
ting the response
"
Set

.
After entering new passwords, execute
PASS <ENTER>
to inspect them. Make sure they
are what you intended. Be sure to write down the passwords after changing them. Be sure to
write down the passwords after changing them. There is no communications procedure to
access the relay without the passwords.
Passwords can be any length up to six numbers, letters, or any other printable character
except the delimiters (space, comma, semicolon, colon, slash). Upper and lower case letters
are treated as different characters. Examples of valid, distinct passwords include:
OTTER otter Ot3456 +TAIL+ !@#$%^ SEL-267D 123456 12345. 12345 ab1CDE
If passwords are lost or you need to operate the relay without password protection, install
Jumper JMP103 on the main circuit board (no password protection). With no password
protection, you may gain access without knowing the passwords and execute the PASSWORD
command to discover or change the
"
forgotten
"
passwords.
SET n
The setting procedure involves answering prompting messages with new data or pressing
<ENTER> to indicate no change. When all data are provided, the new settings are
displayed and a prompt issued requesting your approval to enable the SEL-267D relay with
the new settings. When you complete all desired setting changes, it is not necessary to scroll
through the remaining settings. Type
END <ENTER> after the last setting change to
proceed to the new settings display and enable prompt. The END statement should not be
used for the relay I.D. setting. Use CONTROL-X to abort the set procedure instead.
Error messages indicate when the entered data result in out-of-range settings. If no error
messages are received, the relay is enabled with the new settings, the ALARM contact closes
momentarily, and the event buffer is cleared.
The optional command parameter n can be one of the setting descriptors (except for the ID
setting). The setting descriptor is the abbreviated description of the setting (e.g., 50P1 is the
setting descriptor for the Zone 1 phase overcurrent element). See the following list for more
descriptors. All settings prior to the one specified are skipped when the parameter n is input.
For example, typing
SET Z3DP <ENTER> will skip to the Z3DP setting and start the set
procedure there.
