Frequently Asked Questions
The 'Black cross valve front failed to close' error has occurred. What should I check first?
Check the central 24V supply path from the LEC to the cross-valves, and verify wiring and connections.
My cross valves are not getting pressurized air (7 Bar). Where do I troubleshoot this?
Check the air tube from the Feeding valve in the Bridge pneumatic panel, then check the air outlet 1 from the Main Valve in the Main pneumatic panel. Also, repair any air tubing leakage.
What if a single cross valve fails to close and seems stuck?
Ensure both air feed and voltage are okay. For the stuck valve, remove its cover, confirm the flag does not move when commanded, indicating it needs replacement.
