Set points are entered into memory in three steps: display,
select, and activate, as described below:

1. Press the

VALUE

key until the desired set point is dis-

played flashing on the LCD.

2. Press the

ENTER

key to select this set point. The dis-

played value stops flashing and the

SETUP

icon

flashes on the LCD. This indicates that the value has
been stored in memory but is not yet active. If a new
set point is displayed but not selected by pressing the

ENTER

key (set point value still flashing), then the

displayed set point is not entered into memory and
the original value is maintained. Multiple set point
changes can be made in this fashion without chang-
ing the active settings. For each of these changes, the

SETUP

icon continues to flash.

3. Press the

FUNCTION

key to activate these settings in

the Trip Unit. The

SETUP

icon no longer flashes,

which indicates that any selected settings are also
currently active. The

FUNCTION

key should always be

pressed following set point changes to ensure that the
active settings match the stored settings.

The set point change steps are summarized as follows:

• Display set point – Press the

VALUE

key until the

desired setting is flashing.

• Select set point – Press the

ENTER

key; the setting

stops flashing and the

SETUP

icon starts flashing.

• Activate set points – Press the

FUNCTION

key to acti-

vate the settings; the

SETUP

icon stops flashing.

Always confirm settings on the Trip Unit after making
changes by exiting and re-entering Setup mode and
rechecking each changed setting.
