ALWAYS VERIFY PROGRAMMED SETTINGS BY
ENTERING VIEW SETTINGS AFTER SAVING.
All screens are viewable depending on the programmed
settings and/or Digitrip 1150 model. In particular, the
METER submenu may be programmed to include any-
where from one to 22 viewable screens when METER is
selected, based on the settings chosen in the PGM
SET\DISPLAY screens. Similarly, certain screens are only
viewable based on availability. For example, in the PGM
SET\AuxRLY menu, the selected relay determines the
programmable groups displayed. See Appendix D.
Depending on the Digitrip 1150 model, certain menus or
screens are not viewable or programmable. When using
the LSI factory style unit, viewing and programming menu
screens involving Ground or Earth settings are not acces-
sible. When using the LSIG factory style unit, viewing and
programming screens involving Neutral Protection are not
displayed.
4.1.5 Reset Pushbutton Operation (After Trip)
4.1.5.1 Trip Events
A Reset pushbutton operation does the following after a
trip:
a. Clears the cause of trip flashing LEDs (4) after a trip
event
b. Clears the Trip LED
c. Clears Display data
Note:
After a Trip Event
1. Observe any Trip LED flashing on Mimic Curve.
2. Observe message on LED display.
3. Push View Down pushbutton to observe
timestamp of event and view down to observe
trip current data. This data, along with
timestamp will also be stored in Event Log. The
maximum trip current value that can be
displayed is 65535 A.
4. After any trip condition, the trip unit should be
reset by pressing the Reset Pushbutton.
(See
section 4.1.4.2 on pending Alarm Events)
5. Reclose circuit breaker as desired.
See Appendix D-4 for possible Trip Events and screen data
displayed after a trip by using the View Down (down arrow)
pushbutton.
4.1.5.2 Alarm Events
Alarms are tracked in real time and a Reset pushbutton
may momentarily clear the alarm but the Alarm LED and
Alarm message will reappear if condition is still present.
The ESCape pushbutton activation will remove the alarm
message from the display and return to normal menu
viewing mode, but the yellow alarm LED will remain lit, as
the alarm is in the system
(See Appendix D-22).
Note
: A way to clear an alarm if desired, after
reviewing the alarm and its associated data, is to
enter the PGM SET Menu followed by the ALARM
submenu. The user can then revise or turn off the
associated alarm set point value.
See Appendix D-4 for possible Alarm Events and D-22 for
multiple Alarm conditions.
4.1.5.3 Data resets in Meter screen
A Reset pushbutton operation will reset data values or
group of values if the Reset pushbutton is depressed when
screen value is displayed
(See Appendix D-3 Meter Menu).

Settings
4.2.1.1 General
Before placing any circuit breaker in operation, set each
trip unit protection setting to the values specified by the
engineer responsible for the installation. Each setting is
programmed using the front panel pushbuttons and Save
when the desired settings are selected. A few settings are
interdependent (the LONG PU (
I
r) rating will indirectly
affect the SHORT PU value).
Therefore, always verify
these settings after programming by entering View
Settings Menu.
