Use the Present_Value properties of the Binary_Input objects as alerts for conditions of potential concern regarding to the system
measurement. These values are dynamic and are not latched, so if the condition is resolved, the alert will go inactive, whether it
has been read or not.
These objects support the Description and Reliability object properties and all required Binary_Input object properties. None
of them are writable. For complete assurance, check the Reliability property for a No_Fault_Detected status before reading the
Present_Value.
To test the meter's alert status, read the Present_Value of each of the Binary_Input objects representing the alert bits of interest,
or read the Present_Value of AI52, which combines all 15 bits into a single decimal value. AI52 represents the status of all 15
Binary_Object alert values in one number that can be read without having to access mulitple objects. The bit value of Object BI1 is
the least significant bit and BI15 is the most significant bit (BI15 is only present on the E51H5A).

Range
Phase A Input Voltage exceeds meter's measurement range
Phase B Input Voltage exceeds meter's measurement range
Phase C Input Voltage exceeds meter's measurement range
Phase A Current out of range
Phase B Current out of range
Phase C Current out of range
Phase A Frequency out of range
Returns "INACTIVE"
Phase Loss - Phase A voltage dropped below the Phase Loss Threshold set by
user
Phase Loss - Phase B voltage dropped below the Phase Loss Threshold set by
user
Phase Loss - Phase C voltage dropped below the Phase Loss Threshold set by
user
Phase A Power Factor less than 50% (commonly due to mis-wiring of CTs/PTs
to meter)
Phase B Power Factor less than 50% (commonly due to mis-wiring of CTs/PTs
to meter)
Phase C Power Factor less than 50% (commonly due to mis-wiring of CTs/PTs
to meter)
Real-Time Clock reset. This goes active when the meter is powered after an
interruption (since it does not use a battery backup). It indicates that the
real-time clock has re-initialized to a default setting (00:00:00:00 on Jan 1,
2000) and should not be relied upon. The clock runs, the meter operates and
even logs data (E51H5A oly), but the date and time are not correct until a
Time_Synchronization occurs.
