Frequently Asked Questions
What does Error ID: 16044 mean?
The error indicates that the Black cross valve back failed to open.
How do I troubleshoot if the cross valves are not receiving 24V supply?
Check both the central 24V supply path from the LEC, and verify all wiring and connections. If necessary, switch the power on or off.
What should I check first if air pressure is suspected to be the cause?
First, check the air tubing from the Feeding valve in the Bridge pneumatic panel, then check the air outlet from the Main Valve in the Main pneumatic panel.
How can I test if a specific cross valve or sensor is stuck/faulty?
Check if the cross valve flag moves upon manual ordering. If it does not move, the valve is stuck and must be removed.
Who is authorized to perform the troubleshooting after this stage?
Only an HP certified electrician may perform tests from this point onward due to high voltage systems.
