Display parameter leds at
right
describe
the measurement on the display.
Phase indicator leds at left
describe the
phase related to the display:
2 phase leds are on for Ph-Ph values.
All 3 leds are on for total
cosø, kW,
kVAr.
All leds are off for frequency.
For THD values, THD led,V or A led
and related phase ledsare on
together.
Alarm led
turns on if any fault condition
occurs. If the alarm list is displayed, this
led flashes.
Step leds
turn on if the related capacitor
bank is activated. If the capacitor bank is
faulty, the led flashes once every 5
seconds. When the step is about to
become active or inactive the led flashes
differently.
C- led
shows insufficient regulation.
C+ led
shown excessive regulation.
OK led
indicates a balanced system.
Current display:
If the current
transformer (CT) ratio is lower than
200/5A, currents are displayed with 0.1A
precision. Otherwise they are displayed
with 1A precision.
Voltage display:
If the voltage
transformer (VT) ratio is lower than
50.0/1, voltages are displayed in volts.
Otherwise they are displayed with in kV
with 0.01kV precision.
kW, kVA, kVArdisplay:
If the
VTxCTproduct is lower than 1000, then
values are shown with 0.1k precision.
Otherwise they are shown with 1k
precision.
Capacitor bank rating display:
The
display shows alternatively CAPxand the
rating in kVAr. If the capacitor is single
phase, the related phase led turns on.
Otherwise all phase leds are on.
