4.1.1 Power Up Sequence

When the Digitrip 1150/1150i unit is first powered-up, two
different display messages are possible. If the Digitrip has
been previously commissioned with customer-made
settings, the display will alternate between "Customer
Settings in Use" and "Eaton-Electrical DT 1150" mes-
sages. Following this the display will enter into the main
menu (See Appendix D-1).
If Digitrip settings have not been saved previously the trip
unit is using the factory default values. On power up, the
Digitrip will then display "CHANGE FACTORY SETUP?".
This message will stay on the screen until the user
presses ESCape or the SELect pushbutton or until an
alarm or trip condition is detected.
The ESCape pushbutton action will keep the factory
settings and then will enter the main menu. The factory
settings are listed in Appendix D-25 and are not valid for
most applications. The appropriate settings need to be
defined by a qualified application engineer to provide best
overall protection and coordination for the power system.

A SELect pushbutton action will provide direct entry into
PROGRAM SETTING menu. The first item presented is
the Current CURVE type. LSIG or IEEE or (IEC) current
curve types are possible selections depending on trip unit
style. Pressing SELect again will select the curve pre-
sented in the window center and then step into the indi-
vidual elements that need programmed. The VIEW up and
down arrow selects the function while the EDIT up and
down arrow changes value. After they are set they need to
be saved by depressing the SAVE pushbutton. The saving
will place the customer settings in use. Verify the new
settings. See Appendix D-13 for program curve and D-19
for saving and D-5 for view setting menu.
