10.4 Error 01xx … 13xx ‒ Grid Errors
Error no. Cause of error, error message and corrective measure
01xx
02xx Cause of error
Grid voltage is outside the permissible range or a phase of the power distribution
grid has failed.
Error message 0103
< Grid overvoltage slow >
– Grid voltage is too high. Overvoltage from redundant monitoring
detected.
Error message 0104
< Grid overvoltage fast >
– Grid voltage is too high. Overvoltage from standard monitoring detected.
Error message 0203
< Grid undervoltage slow >
– Grid voltage is too low. Undervoltage from redundant monitoring
detected.
Error message 0204
< Grid undervoltage fast >
– Grid voltage is too low. Undervoltage from standard monitoring detected.
Error message 0205
< Grid failure >
– A power distribution grid phase has failed.
Measure
< Check grid voltage >
– Check the grid voltage.
– Check grid connections.
– See if the power distribution grid is stable.
– Make sure the external fuses are working properly.
– Make sure the AC cable is connected securely.
