2.3 Phase Absent Screen

This screen is one of the Voltage / Current Parameter Screens and is useful to indicate if voltage or current in

any phase is absent. Hence, user will know which voltage or current is missing and take corrective action.

This screen indicates that all three

phases (V & I) are absent.

This screen indicates that V2,

I2 and I3 are absent.

This screen indicates that all

three phases are present i.e.

all inputs are present.

2.4 Individual Harmonics

XXXX

2.5 Load Health Monitor Screen

The Individual Harmonics can be accessed by

pressing the Enter key followed by the Up and

Down keys taking through the 31 harmonics.

Similarly, pressing the “ ” key at the quit screen

The Load Health Monitor Menu is one of the System Parameter

Screens and shows the health status of the three phase load. The faults

can be monitored by pressing the Enter Key followed by the Up and

Down keys taking through all the different errors (if any) of the Three

Phase load. Types of Error shown :

1) Phase Fail 2) Unbalanced Voltage

3) Unbalanced Current 4) Phase Reversal

5) Under Frequency 6) Under Voltage

7) Over Current 8) Over Voltage

This screen is one of the Voltage / Current Parameter Screens.
