Latched Faults Faults are cleared when the device is
either reset by the network or detects
current flowing.
The fault bits are defined as follows:
Bit Feature
0 Overload Fault
1 Phase Imbalance
2 Phase Loss Fault
3 Ground Fault
4 Network Trip Command
5 NV Memory Failure
6-> Reserved
- 307 R Current

of FLA
Current as a percentage of FLA. Ie: If
Current is 1Amp and the FLA is 1AMP the
percent would be 100%. ( % )

Current RMS
Scaled Ground Current. ( Amps )
- 311 R Scaled
FLA
Setting
The present FLA setting. The potenti-
ometer selects this value. The value is
scaled by the multiplier. ( Amps )
- 312 R Overload
Class
The present FLA class. Class settings are
device dependent.

Line Frequency The line frequency measured by the
device. The frequency is displayed in
deciHz. ( Hertz )

Feature States The feature status bits are defined as
follows:
Bit Feature
01 Class Index (00 = Class 10; 01 =
Class 15; 10 = Class 20; 11 = Class 30)
2 Phase Loss/Imbalance Enabled
3 Ground Fault Enabled
4 Auto Reset Enabled
5 Remote Reset Active
6 Dip Switch Position 0
7 Dip Switch Position 1
8 Dip Switch Position 2
9 Dip Switch Position 3
10-15 Reserved

Temperature
The temperature as seen by the micro-
controller. Accuracy ~ 10%. ( ºC )

Trip/Reset
Control
When a state change is requested the
bit will remain active until the device is
able to execute the command. The bits
are auto clearing after the state has been
changed. Any other bits will simply be
cleared.
The following bits are defined:
Bit Action
0 Cause a Trip (will override a reset).
1 Cause a Reset
- 396 R Scaled
Min
FLA
This is the min FLA setting possible in
this device. The value is scaled by the
multiplier. ( Amps )
- 397 R Scaled
Max
FLA
This is the max FLA setting possible in
this device. The value is scaled by the
multiplier. ( Amps )
- 398 R Current
Scale
Value
This value indicates the multiplier applied
to the current values. For example: If the
multiplier is 10 then all currents are read
out in deciamps. 1A => 10A. ( Scale )

- 428 R Firmware
Revision
The firmware revision is stored in 32bit
format. 0xMMmmbbbb. Where M =
Major Revision, m = Minor Revision and
b = Build Number.
- 429 R Firmware
Build
The firmware build is a 16 bit number.
0xbbbb - b = Build Number.

Checksum
The 32 bit checksum of the code. A
simple 16 bit addition checksum.

Modbus
Production
List
The Production and consumption
Registers can be used to create custom
Modbus interface ranges. An example:
If field inputs register address 0 is put
into the first slot of the production
list, the field inputs register value will
be available in the first slot of the
Modbus Production Data Register range.
Production data is data provided by the
device and Consumption data is for data
provided (written) to the device. Note
that the values must be Modbus Register
Address (i.e., Register Number - 1) not
Register Number.
