After entering new passwords, type PAS <ENTER> to inspect them. Make sure they are what
you intended, and record the new passwords.
Passwords may include up to six characters. Valid characters consist of: ‘A-Z’, ‘a-z’, ‘0-9’, ‘-’,
and ‘.’. Upper- and lower-case letters are treated as different characters. Examples of valid,
distinct passwords include:
OTTER otter Ot3456 TAIL 123456 12345. 12345-
If the passwords are lost or you wish to operate the relay without password protection, put the
main board Password jumper in place (Password jumper = ON). Refer to Tables 2.6 and 2.7 for
Password jumper information.
If you wish to disable password protection for a specific access level [even if Password jumper is
not in place (Password jumper = OFF)], simply set the password to DISABLE. For example
PAS 1 DISABLE disables password protection for Level 1.
