Inlet-Valve Fuse

 

The active-inlet valve in the quaternary pump has drawn excessive current

 

causing the inlet-valve electronic fuse to open.

Probable Causes

• Defective active inlet valve.

 

• Defective connection cable (front panel to LPM board).

 

• Defective LPM board.

Suggested Actions

❏ Restart the quaternary pump. If the error message appears again, exchange

 

the active inlet valve.

 

❏ Exchange the connection cable.

 

❏ Exchange the LPM board.
