Command Explanations
Access Level 0 Commands
ACC, EAC, and 2AC Commands (Go to Access Level 1, E, or 2)
The ACC, EAC, and 2AC commands provide entry to the multiple access
levels. Different commands are available at the different access levels as
shown in Table 10.24. Commands ACC, EAC, and 2AC are explained
together because they operate similarly.
➤ ACC moves from Access Level 0 to Access Level 1.
➤ EAC moves from Access Level 1 to Access Level E.
➤ 2AC moves from Access Level 1 or E to Access Level 2.
Password Requirements
Passwords are required at all access levels except Access Level 0. See the PAS
Command (View/Change Passwords) on page 10.31 for the list of default
passwords and for more information on changing passwords.
Access Level Attempt
At the Access Level 0 prompt, enter the ACC command:
=ACC <Enter>
The meter asks for the Access Level 1 password:
Password: ? @@@@@@
The meter is shipped with the default Access Level 1 password (OTTER)
shown in Table 10.20. At the prompt above, enter the default password and
press the <Enter> key. The meter responds:
FEEDER 1 Date: 03/05/01 Time: 08:31:10.361
STATION A Time Source: ext
Level 1
=>
The => prompt indicates the meter is now in Access Level 1.
If the entered password is incorrect, the meter asks for the password again
(
Password: ?). The meter will ask up to three times. If the requested
password is incorrectly entered three times, the meter pulses the SALARM bit
for one second and remains at Access Level 0 (= prompt).
The procedure to go from Access Level 1 to Access Level 2, Access Level 1 to
Access Level E, or Access Level E to Access Level 2 is much the same, with
command EAC or 2AC entered at the access level screen prompt. The meter
pulses the SALARM bit for one second after a successful Level 2 or Level E
access. If access is denied, the SALARM bit pulses for one second.
If you are unable to enter the correct password after the third failed attempt,
the SEL-734 asserts the SALARM Meter Word bit and displays the following
error message on a communications terminal screen:
