The password disable jumper, PASSWORD, is for temporary or emergency
suspension of the relay password protection mechanisms. Under no
circumstance should you install PASSWORD jumper on a long-term basis. To
ensure the PASSWORD jumper, in particular, is not inadvertently left in the
ON position, the relay asserts Relay Word bits PASSDIS and BRKENAB to
indicate the presence of the password disable jumper (PASSDIS) and the
breaker jumper (BRKENAB). The relay ships with password disable jumper
PASSWORD OFF (passwords enabled). For temporary unprotected access to
a particular access level, use the PAS n DISABLE command (n is the access
level: n = 1, B, P, A, O, 2). For more information on this command and setting
passwords, see Password on page P.7.13.
The circuit breaker control enable jumper, BREAKER, supervises the
CLOSE n command, the OPEN n command, the PULSE OUTnnn
command, and front-panel local bit control. To use these functions, you must
