4.1.0 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 "Cutler-
Hammer DT 1150" and "Customer Settings in Use"
messages. 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 if 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
setting are listed in Appendix D-23 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
individual 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.
