Description:

This error code indicates that the Corner Post Display Unit (PDU) is not receiving the required messages from the Selective Control Valve Control Unit (SCC). This can occur due to communication failures, wiring issues, or faults within the SCC or PDU.

Reaction:

There is no immediate reaction from the control unit; however, the absence of these messages can lead to incomplete or missing information regarding selective control valves on the PDU, affecting the operator’s ability to monitor and control these valves.

Recommendations:

• Inspect Communication Lines:
  • Check the wiring and connectors between the PDU and SCC for any signs of damage, loose connections, or interference.
• Verify SCC Operation:
  • Ensure that the SCC is functioning properly and transmitting the required messages.
• Update Software:
  • Update the software of both the PDU and SCC to the latest versions to ensure compatibility and proper communication protocols.
• Reset the System:
  • Perform a system reset to reestablish communication between the PDU and SCC.
• Consult Technical Support:
  • If the communication issue persists, contact technical support for further diagnostics and solutions.

Note:

Regular checks and maintenance of communication lines, along with timely software updates, are essential for preventing such issues and ensuring reliable operation of selective control valves.
