Hi Guys,

Thanks for your valued inputs.

The power ON button has been pressed and the machine was in NOT READY STATUS.

No input signal from X16,17,18,20,21,22 ( LK1 flat cable connected from I/O board to relay PCB Yang SML-12-001).

No input signal from X0,2,4,6,8 (LK3 flat cable connected from I/O board to operator panel)

No output signal from Y48,49,50 and 52 ( LK2 flat cable connected from I/O board to relay PCB Yang SML-12-001).

I've suspect that Relay PCB cuasing the problem? But this machine is already obselete in the market and the Yang machine builder already closed whcih difficult to find the replacement parts.

Could you please advise.

Many Thanks,
CNC Miles
