Internal signal description
Symbol
Name
Description
ZCR
Zero crossing signal
Provides positive pulse every time the line voltage crosses zero
AW
Active energy
Pulse frequency signal proportional to active energy
RW
Reactive energy
Pulse frequency signal proportional to reactive energy
SW
Apparent energy
Pulse frequency signal proportional to apparent energy
LIN
Line frequency signal
This signal is high when the voltage channel value is rising and it is low when
the voltage channel is falling. Basically this signal is the sign of dv/dt.
BFR
Base frequency range
This signal is high when either the voltage line frequency is outside the
nominal band or the voltage register is below 64.
It is cleared when the voltage line frequency is inside the nominal band and
the voltage register goes above 128.
MA
Stepper motor signals
Signal available in MOP and MON to drive a stepper motor
MB
BIT
Tamper flag
This signal provides the information on the tamper status. If low no tamper is
detected, when high a tamper condition has been detected. This signal is part
of the status register but is also available on the SDATD pin when in
standalone mode.
BIL
No load condition
Provides information on the load condition. This signal is part of the status
register but is also available on the SCLNLC pin when in standalone mode.
BIL=1 no load condition, BIL=0 normal operation.
