A command or setting write operation is required to update the state of all the remote and local security operands
shown above. Changing the password, or any other setting, does not take the relay out of service. The relay is
taken out of service when a settings file is written to it.

CHANGE LOCAL PASSWORDS
Proper password codes are required to enable each access level. A password consists of 1 to 10 numerical characters.
When a
CHANGE COMMAND PASSWORD
or
CHANGE SETTING PASSWORD
setting is programmed to “Yes” via the front panel
interface, the following message sequence is invoked:
1.
ENTER NEW PASSWORD: ____________.
2.
VERIFY NEW PASSWORD: ____________.
3.
NEW PASSWORD HAS BEEN STORED.
To gain write access to a “Restricted” setting, program the
ACCESS LEVEL
setting in the main security menu to “Setting” and
then change the setting, or attempt to change the setting and follow the prompt to enter the programmed password. If the
password is correctly entered, access will be allowed. Accessibility automatically reverts to the “Restricted” level according
to the access level timeout setting values.
If an entered password is lost (or forgotten), consult the factory with the corresponding
ENCRYPTED PASSWORD
.
If the setting and command passwords are identical, then this one password allows access to both com-
mands and settings.
If a remote connection is established, local passcodes are not visible.
