Date Code 20080213 Instruction Manual SEL-351A Relay
Serial Port Communications and Commands
Command Explanations
If the entered password is incorrect, the relay asks for the password again
(
Password: ?). The relay will ask up to three times. If the requested password
is incorrectly entered three times, the relay closes the ALARM contact for one
second and displays an invalid access message.
Access Level Attempt (Password Not Required)
Assume the following conditions:
➤ Password jumper = ON (in place)
➤ Access Level = 0
At the Access Level 0 prompt, enter the ACC command:
=ACC <Enter>
Because the Password jumper is in place, the relay does not ask for a
password; it goes directly to Access Level 1. The relay responds:
FEEDER 1 Date: 08/10/99 Time: 08:31:10.361
STATION A
Level 1
=>
The => prompt indicates the relay is now in Access Level 1.
The above two examples demonstrate how to go from Access Level 0 to
Access Level 1. The procedure to go from Access Level 1 to Access Level B,
Access Level 1 to Access Level 2, or Access Level B to Access Level 2 is
much the same, with command BAC or 2AC entered at the access level screen
prompt. The relay closes the ALARM contact for one second after a successful
Level B or Level 2 access. The ALARM contact also closes for one second if
access is denied.
Access Level 1
