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.
