Description

ICHANNEL7

This bit indicate the current channel used to measure energy in anti-

tampering mode.

0 – Channel A

1 – Channel B

FAULTSIGN1

Configuration bit to select event that will trigger a Fault interrupt

0 – FAULT interrupt occurs when part enters Fault Mode

1 – FAULT interrupt occurs when part enters Normal Mode

VARSIGN8

Configuration bit to select event that will trigger an reactive power sign

interrupt

0 – VARSIGN interrupt occurs when reactive power changes from positive

to negative

1 - VARSIGN interrupt occurs when reactive power changes from negative

to positive

APSIGN

Configuration bit to select event that will trigger an active power sign

interrupt

0 – APSIGN interrupt occurs when active power changes from positive to

negative

1 - APSIGN interrupt occurs when active power changes from negative to

positive

ABSVARM2

Logic one enables absolute value accumulation of Reactive power in

energy register and pulse output

SAVARM2

Logic one enables reactive power accumulation depending on the sign of

the active power:

If Active Power is positive, VAR is accumulated as it is;

If Active Power is negative, the sign of the VAR is reversed for the

accumulation.

This accumulation mode affects both the VAR registers and the VARCF

output.

POAM

Logic one enables positive only accumulation of Active power in energy

ABSAM

Logic one enables absolute value accumulation of Active power in energy
