Is there any wrong in this manner?
Please help us.

Indicates that input signal "locking valve 25V" to board CPxx has not been set, i.e. the 25-V voltage supply of locking valve Y315 must be verified.

 

Thank you for the reply Mr. Chock I found the problem the F4 Bridge leg was little burnt hopefully the problem is in control.
Thanking you.
