Description
Fault Code (4)5 is triggered when the device detects an unexpected voltage at the heater output terminals. This can occur if the terminals are connected to a power supply or if there is an incorrect or faulty connection in the heater wiring.
Checks to Perform
1. Ensure Heater Output Terminals Are Not Connected to Any Supply Voltage
- Verify that the heater output terminals are not accidentally connected to any external power supply.
- Double-check the wiring to ensure there are no unintended connections to live circuits.
- If the heater is part of a larger system, ensure no back-feeding of power from other devices or sources.
2. Inspect Heater Wiring for Incorrect Connections or Faults
- Carefully examine the heater wiring for any signs of damage, incorrect connections, or short circuits.
- Look for wires that may have come loose or are incorrectly attached to the wrong terminals.
- If there are any signs of wear or faults, repair or replace the wiring as needed.
Post-Check Actions
- After making the necessary corrections, reset the system and check if the error persists.
- If the fault code clears, monitor the system during normal operation to ensure the issue does not reoccur.
- If the error remains after performing these checks, contact technical support for further guidance and assistance.
Preventative Recommendations
- Regularly inspect and maintain the heater wiring to prevent faults or incorrect connections.
- Ensure that all connections are made according to the manufacturer’s wiring diagrams and instructions.
