Using the Field Unit
PhaseTrakker
AP30
22
When the Field Unit is configured for ACB Phase Sequence, the order of the
phase labels is automatically changed on the display. The positions and audible
signals, however, continue to reflect the time sequence order of the phases. If the
Sequence is set to ACB for AP20, the 2
nd
and 3
rd
Phase beeps are switched for
the convenience of users accustomed to the previous model.
Phase Labels
The phase identifications for ACB Phase Sequence are the same. The measured
phase angle is displayed next to the label of the phase identified and an audi-
ble signal is given: Top position with 1 beep for the 1
st
Phase in time sequence,
middle position with 2 beeps for the 2
nd
Phase, and bottom position with 3 beeps
for 3
rd
Phase.
