5.4 SM3000 Energy meter diagnostics
5.4.1 SM3000 FEATURES
The SM3000 detects the grid energy of up to 3 phases and indicates it the site overall is importing or exporting energy.
Power
ON: Meter has power
OFF: Meter does not have power or has failed
Energy
Flow
ON: Site is consuming energy from the grid
Flashing: Site is exporting energy to the grid
OFF: Energy flow is not detectable
Comm’s
Flashing: Transmitting data
5x Flash: Reset in progress
