Alarms become “1” when
thresholds exceeded.
Note: Additional Status Alert is
Located at addr 0xBD (see Table 8)
Note: When AC voltage input is less
than or equal to 10 V
RMS
,
• Only MINVA alarm is active.
• All measurements are forced
to 0 except power factor,
which is forced to 1.
Note: The frequency measurement
is forced to 0 as long as the SAG
voltage alarm is active.
