Fault Codes (4)6 and (4)7 Over/Under Voltage!

These fault codes indicate issues with the AC supply voltage either exceeding or dropping below the acceptable range. Both errors can affect the performance of the device and require immediate attention to ensure safe and reliable operation.

Fault Code (4)6: Over Voltage!

Fault Code (4)7: Under Voltage!

Fault Code (4)6 occurs when the AC supply voltage exceeds 260V. This over-voltage condition can cause damage to the device and should be addressed promptly to avoid any potential harm.

Checks to Perform

  1. Measure the AC Voltage at the SUPPLY Terminals
    • Use a reliable multimeter or voltmeter to measure the voltage at the SUPPLY terminals.
    • Ensure the voltage reading is below 260V.
  2. Ensure the Voltage Is Below 260V
    • If the voltage exceeds 260V, the issue is likely with the incoming power supply.
  3. Consult Your Electricity Provider or a Qualified Electrician
    • If the voltage remains high, contact your electricity provider to report the over-voltage condition.
    • A qualified electrician may need to inspect the power supply and make any necessary adjustments or repairs to ensure the voltage is within safe limits.

Fault Code (4)7 is triggered when the AC supply voltage drops below 190V. This under-voltage condition can prevent the device from operating properly and should be addressed to maintain stable performance.

Checks to Perform

  1. Measure the AC Voltage at the SUPPLY Terminals
    • Use a multimeter or voltmeter to check the voltage at the SUPPLY terminals.
    • Ensure the voltage reading is above 190V.
  2. Ensure the Voltage Is Above 190V
    • If the voltage is below 190V, the issue lies with the incoming power supply.
  3. Consult Your Electricity Provider or a Qualified Electrician
    • If the voltage remains low, contact your electricity provider to report the under-voltage condition.
    • A qualified electrician can inspect the electrical system to identify and resolve the issue.

Post-Check Actions

  1. Once the AC supply voltage is within the correct range (below 260V for over voltage, above 190V for under voltage), reset the device and verify that the error code is cleared.
  2. If the error persists despite resolving the voltage issue, or if you are unable to adjust the voltage, seek further assistance from technical support.

Preventative Recommendations

  • Regularly monitor the incoming AC voltage to ensure it stays within the required range.
  • Install a surge protector or voltage stabiliser to prevent damage from fluctuating supply voltages.
  • Ensure the system is installed correctly according to the voltage requirements outlined in the device manual.
