Digital Input Control
• Set Control—To configure conditional energy for digital input
control:
1. Write command code 9020 to register 8000.
2. In register 3227, set bit 6 to 0 (preserve other bits that are
ON).
3. Configure the digital input that will drive conditional energy
accumulation. For the appropriate digital input, write 3 to the
Base +9 register. See the digital input templates in Table A–3
on page 122 in Appendix A—Meter Register List
on page 119.
4. Write 1 to register 8001.
5. Write command code 9021 to register 8000.
• Clear—To clear all conditional energy registers (1728–1747),
write command code 6212 to register 8000.
• Verify Setup—To verify proper setup, read register 1794. The
register should read 0 when the digital input is off, indicating that
conditional energy accumulation is off. The register should read 1
when conditional energy accumulation is on.
Incremental Energy
The meter’s incremental energy feature allows you to define a start
time, end time, and time interval for incremental energy
accumulation. At the end of each incremental energy period, the
following information is available:
• Wh IN during the last completed interval (reg. 1748–1750)
• VARh IN during the last completed interval (reg. 1751–1753)
• Wh OUT during the last completed interval (reg. 1754–1756)
• VARh OUT during the last completed interval (reg. 1757–1759)
• VAh during the last completed interval (reg. 1760–1762)
• Date/time of the last completed interval (reg. 1763–1765)
• Peak kW demand during the last completed interval (reg. 1940)
• Date/Time of Peak kW during the last interval (reg. 1941–1943)
• Peak kVAR demand during the last completed interval (reg. 1945)
• Date/Time of Peak kVAR during the last interval (reg. 1946–1948)
• Peak kVA demand during the last completed interval (reg. 1950)
• Date/Time of Peak kVA during the last interval (reg. 1951–1953)
