Frequently Asked Questions
What is the immediate safety warning for troubleshooting this system?
Do not touch any wiring while the system is UP, as it is a High Voltage System; only an HP certified electrician may perform tests.
How do I check if the cross valves are getting proper electrical power (24V)?
Check the central 24V supply path from the LEC to the cross-valves, and inspect all wiring and connections for continuity.
What should I do if the cyan cross valve fails to close?
First, check air leakage in tubes, then verify the pressurized air feed from both the Main Valve and the Feeding valve using disconnectable fittings.
My cross-valve flag moves but the sensor state doesn't change; what does that mean?
If voltage is confirmed, it indicates that the optic sensor itself is faulty and needs to be replaced.
