Alarms become “1” when
thresholds exceeded.
Note: Additional Status Alert is
Located at addr 0xBD (see Table

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.
