Password Access
Press OTHER. A three-command OTHER MENU is displayed: 2AC, BRE, and QUI. QUI
returns the front panel to Access Level 1. With BRE or 2AC displayed, press SELECT and enter
your password for Breaker Access Level or Access Level 2 by scrolling through the set of valid
password characters displayed with the (↑) and (↓) buttons. Use the (←) and (→) buttons to
move the cursor between characters. Use the SELECT button to deposit the selected character in
the password position and advance the active password character. Press EXIT to complete the
password entry and validate the password. If you press CANCEL before the password is
completely entered, the cursor moves to the active password position and you must use the arrow
buttons and the SELECT button to select a new active password character position.

(see Password Access). There are three settings options: SET GROUP (group settings, Table

select the setting dialogue, the relay comes up in SET GROUP. Push the Left or Right (← →)
