Theoretical Maximum System Power – This is the
theoretical maximum power the meter expects to see
on a service. It is calculated by the meter from the
System Type (in object AV2), CT Size (in object AV3),
and System Voltage (in object AV6) - Power Factor is
assumed to be unity. The register is updated whenever
the user changes any of these parameters.

This contains a decimal value that represents the status
of all Binary_Object alert values in one number that can
be read without having to access mulitple objects (the
E50H2 has 14 values, the E50H5 has 15). It is a decimal
representation of a 14-bit or 15-bit hexidecimal value
produced by combining the alert bits into one number,
where the bit value of Object BI1 is the least significant
bit and BI14 or BI15 is the most significant bit.
Binary_Input Objects
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 Reliabilty 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 these bits into a single decimal value. AI52 represents the status of all 14 or 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 BI14 or BI15 is the most significant bit (BI15 is only present on the E50H5).
