Phase Loss Voltage Threshold in percent of system voltage (register
134). Default is 10 (%). Any phase (as configured in register 130)
that drops below this threshold triggers a Phase Loss alert - i.e.
if the System voltage is set to 480 V L-L, the L-N voltage for each
phase should be 277 V. When the threshold is set to 10%, if any
phase drops more than 10% below 277 V, (less than 249 V), or
if any L-L voltage drops more than 10% below 480 V (less than
432 V) the corresponding phase loss alarm bit in register 146 will
be true.
Phase Loss Output
Note: The phases tested are determined by
the System Type.

Phase Loss Imbalance Threshold in Percent. Default is 25% phase
to phase difference. For a 3-phase Y (3 + N) system type (40 in
register 130), both Line to Neutral and Line to Line voltages are
tested. In a 3-phase Δ System type (31 in register 130), only Line
to Line voltages are examined. In a single split-phase (2 + N)
system type (12 in register 130), just the line to neutral voltage
are compared.

Pulse Contact Closure Duration

slowest duration that will keep
up with the theoretical max.
system power (register 135).
The open time ≥ the closure
time, so the max. pulse rate
(pulses per sec) is the inverse of
double the pulse time.

Diagnostic Alert Bitmap. 1 = Active:
Bit 0: Phase A Voltage out of range
Bit 1: Phase B Voltage out of range
Bit 2: Phase C Voltage out of range
Bit 3: Phase A Current out of range
Bit 4: Phase B Current out of range
Bit 5: Phase C Current out of range
Bit 6: Frequency out of the range of 45 – 65 Hz OR there is insufficient voltage to determine frequency.
Bit 7: Reserved for future use
Bit 8: Phase Loss A
Bit 9: Phase Loss B
Bit 10: Phase Loss C
Bit 11: Low Power Factor on A with one or more phases having a PF less than 0.5 due to mis-wiring of phases
Bit 12: Low Power Factor on B
Bit 13: Low Power Factor on C
Bit 14: Energy pulse output overrun error. The pulse outputs are unable to keep up with the total real power
(registers 3 and 261/262). To fix, increase the pulse energy register (register 144) and reset the energy
accumulators (see reset register 129).
Bit 15: Energy pulse output configuration error (present pulse energy setting may not keep up with the
theoretical max. system power; see register 135). To fix, increase the pulse energy (register 144).
