Set points are entered into memory in three steps:
display, select, and activate, as described below:
1 1 1 1.... Press the
VALUE key until the desired set point
is displayed flashing on the LCD.
2 2 2 2.... Press the
ENTER key to select this set point. The
displayed 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
changing the active settings. For each of these
changes, the
SETUP icon continues to flash.
3 3 3 3.... Press the
F U N C T I O N
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
F U N C T I O N 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 S E T U P icon starts
flashing.
• Activate set points – Press the
FUNCTION
key to
activate 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.
