What does it mean when solenoid valve does not open?
1. Solenoid Valve Not Opening A solenoid valve should open when it’s required to. If it doesn’t, it means there is a fault somewhere. It could be insufficient voltage across the wire leads of the solenoid valve coil, which is usually termed as power failure.
What kind of solenoid is used for air system purge?
ASCO or SMC brand 2-Port solenoid valves are most commonly used for the air system purge. These solenoids are also used in the Coolant Refill and TAB options. Note: MAC 3-Port poppet style solenoid valves are also used for the air system purge. There is a plug on port number 3 when MAC 3-way poppet style solenoid valves are used.
What should I do if my solenoid is not activated?
Use the approved replacement solenoid. If these solenoids leak air when the solenoid is not activated, it is likely that debris holds the plunger in an open position. Follow this procedures to clean the 2-Port air purge solenoid valve: Remove the red cap [1]. Push the solenoid coil assembly [2] down to compress the spring inside.

What kind of solenoid valve does a Haas machine use?
3-Port poppet style solenoid valves are the most common solenoid valves used on Haas machines. These illustrations show how a normally-closed MAC 3-Port poppet style solenoid valve operates: Black arrows illustrate air pressure from the air supply. Grey arrows illustrate exhaust flow from the machine.
Why is my solenoid not working with correct air pressure?
If you command the solenoid to open or close without the correct air pressure, the solenoid can go into an intermediate state that may not correct itself when the machine has correct air pressure. To move the solenoid out of the intermediate state, close the air valve and power off the machine.
