section below.
T
he controller will consistently display the Home Screen on the LCD showing the highest
phase's current, in amps, and the highest temperature in
°
F (when used). Also shown is the number
of trips that have been automatically reset since the last manual reset occurred, due to either an over
current condition or an abnormal temperature value, or a combination of the two.
By pressing and holding
down one of the
buttons shown below, while the Home Screen is
present on the LCD,
the following information will be displayed on the LCD:
DOWN
button - Disp
lays, in real time,
the current in each of the three (3) load's phases and the
two (2)
temperature
sensors
,
even when the
y are not installed or have not been selected. Unused or
un-selected current and temperature sensor inputs are shown as "
0
".
UP
button - Display
s the
last automatically reset trip, including the type of trip, the trip value,
and the time since that trip occurred (in hours).
OR
The LCD shows the stored current values that caused a phase imbalance during a part (split)
winding motor startup
.
T
he current value that is displayed on the Home Screen represents the maximum current pres-
ently being sensed by the CTs and
is used for the over current trip calculation.
