10.2.2 Errors 01-13 - Power Distribution Grid Errors
Error number Cause and corrective measures
01 The line voltage is too high. Error type: Fault (see section 10.2.1 "Error
Types and Waiting Times for Errors", page 56).
Corrective measures:
• Measure the line voltage.
If the line voltage is outside of the permissible range, adjust the line
voltage on the medium-voltage transformer as required.
02 The line voltage is too low. Error type: Fault (see section 10.2.1 "Error
Types and Waiting Times for Errors", page 56).
Corrective measures:
• Measure the line voltage.
If the line voltage is outside of the permissible range, adjust the line
voltage on the medium-voltage transformer as required.
• Ensure that external fuses are functioning.
• Ensure that the AC cables are connected correctly.
05 The power frequency is outside the permitted range. Error type:
Fault (see section 10.2.1 "Error Types and Waiting Times for
Errors", page 56).
Corrective measures:
• Measure the line voltage.
If the line voltage is outside of the permissible range, adjust the line
voltage on the medium-voltage transformer as required.
• Ensure that external fuses are functioning.
• Ensure that the AC cables are connected correctly.
08 A line conductor has failed. Error type: Fault (see section 10.2.1 "Error
Types and Waiting Times for Errors", page 56).
Corrective measures:
• Measure the line voltage.
If the line voltage is outside of the permissible range, adjust the line
voltage on the medium-voltage transformer as required.
• Ensure that external fuses are functioning.
• Ensure that the AC cables are connected correctly.
