Scenario with a circuit breaker: If the countercurrent feeding into the power grid cannot
be eliminated by sending a command from the SmartLogger to lower the solar inverter
output power, and Maximum protection time is exceeded, the SmartLogger drives the
relay to switch off the circuit breaker by controlling the DO port to prevent
countercurrent. When the DI port detects that the circuit breaker is switched off, the DO
port of the SmartLogger and the relay will be switched off, and the SmartLogger will
restore to the initial state.
Connect the DO ports in series to the 12 V power supply loop of the relay coils. You are advised to use
the 12 V power output port on the SmartLogger to power the relay coils. You can also prepare a 12 V
power supply.
