This error appears when the PowerRouter Shunt detection has failed.
Without it, the PowerRouter cannot measure the current flow to and from the batteries.
Therefore it switches off. The Shunt detection is Battery powered.
- Verify all battery connections and SOC; is battery voltage adequate?
- In most cases, a restart will resolve the issue.
However, should this happen very often, it could be that the shunt calibration is off and the PowerRouter must be replaced. Contact Nedap PowerRouter Support.
