It will reset itself a couple of times, then lock out if the event continues.
  • Page 44 What is it? This alarm shows there is fault current flowing in the utility connection. Downstream Fault SELF Why is it an alarm? If there is a downstream fault, the PureWave SMS-250 system should not move Detected to the Island mode because the utility is better at restoring the voltage than the PureWave SMS-250 system.
  • Page 45 What can the user do? A reset may clear the problem. If not contact S&C. Lost Synchronize What is it? The PureWave SMS-250 inverter synchronizes to the voltage input at its terminals using a SELF Phase Lock Loop (PLL). The PLL should always be locked to the input voltage. However, it is possible that the PLL could lose its lock.
  • Page 46 Why is it an alarm? Current feedback is essential to the PureWave SMS-250 inverter. If we lose a power supply, the current feedback will not follow the primary current. This will cause misoperation of the inverter.
