Frequently Asked Questions
What is the first step when diagnosing error ID 66039?
Check if the cross valves receive 24V supply from both the central path and by verifying that air pressure is supplied to the feeding valve.
How should I check for low pneumatic pressure (7 Bar)?
First, check the pressurized air feed from the Feeding valve in the Bridge pneumatic panel. If necessary, also inspect the Main Valve's air outlet and repair any tubing leaks.
What does it mean if the cross-valve flag moves but the sensor reading doesn't change?
This indicates that the optic sensor is faulty and should be replaced, assuming the valve still receives proper voltage.
