3.1.3.3 Units LEDs: Auto Range Units for Monitoring
The units for monitoring are Units, Kilo-Units, and
Mega-Units. Figure 3.1 (p.8) shows the location of
these LEDs to the right of the display window. These
units are fixed, based on your selection for PT and CT
ratios so that the display is consistent with the PT and
CT sizes. They let you know the measurement unit for
the displayed function.
3.1.3.4 Alarm LED’s
The Alarm LEDs, (Alarm 1, Alarm 2) when continuously
lit, indicate that an alarm condition exists. If there is an
alarm condition when you press the Alarm Data button,
the corresponding LED blinks and the display window
shows a digit, from 1 to 8. This digit represents the
specific type of alarm condition that is occurring for the
selected alarm. The alarm cause codes are listed at the
bottom of the faceplate for easy reference. Table 3.A
describes the alarm codes by number.
