Alternate source sense(PM1230H) Alternate source sense

Alternate source sense terminals detect the status of alternate power sources.

Source 1 in the meter connects to utility and Source 2 connects to alternate source. The two terminals are connected with a 1Ph LN alternate power source. When Source 2 is turned on, voltage flows through the meter and the system is powered with alternate source.

The meter measures energy accumulation and run hours on the alternate source. The total energy used by the meter is the sum of accumulated energy for Source 1 and Source 2. Total run hours of the meter is the sum of run hours of Source 1 and Source 2. Total accumulated energy, and run hours can be viewed through meter display, and through communication.

NOTE: Old accumulated energy and run hours can be viewed through display and communication for Source 1 and Source 2.
