Check the Alternate Substation tables for up-to-date information on 

Alternate Substations that can feed the primary sub.
For more information on Alternate Substation tables, see the Adding 

Alternate Substation Information section in the SCE Maintenance chapter 

of the TNS End User Guide. Also see the Alternate Substation Mapping and 

Creating and Using Alternate Path Tables sections in the Building and 

Searching Alternate Paths chapter of the TNS Operational Process Guide.

There is one byte within the Total Consumption reading (present or frozen) which 

contains data that may be invaluable for diagnosing and troubleshooting issues 

prior to rolling a truck.

Total Consumption (TC) registers (Present and Frozen Daily) on the EMTR-3 

contain a three byte TC value and a one byte status. In the status, the Hour of 

Reading and Configuration field is used to establish a desired level of validity for 

the TC reading. This five bit field also serves as a quick alternate method for time 

stamping the data.

The Hour of Reading and Configuration field provides a number of different levels 

of information. There are four error conditions the field can report and if none of 

those errors are present, the field is an indication of the quality of the TC reading.
