Description

Phase Loss Voltage Threshold in percent of system

 

voltage (register 134). Default value is 10 (%). Any

 

phase (as configured in register 130) whose level

 

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

Phase Loss Output

L-L voltage drops more than 10% below 480 V (less

 

than 432 V) the corresponding phase loss alarm bit in

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-neu- tral and line-to-line voltages are tested. In a 3-phase 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.

Error 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 to 65 Hz -OR- 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).
