Hello, i am trying to troubleshoot a 9161 (machine not ready) alarm on startup. I've followed the fault tree and even replaced a thermal 24vdc contactor in the circuit, but still no help.

If anyone has ever had this alarm in the past, what steps did you take to correct? Also, if any available documentation, that would be helpful too.
Thanks
Andy

Andy,

Probably not much help but my book says:
Cause: No "machine ready signal" or "hydraulic on" signal.
Action: Check breaker QFB2, QFB3 and thermal relay QFB6.
Check the "machine ready signal" and connections.
Check the magnetic contact and thermal relay of hydraulic pump motor.

Afraid that is about all the help I can offer. If you have found a solution, please post for the rest of us.

I just got this error too. It is not listed in my book. What manual are you looking in that lists it and shows a trouble tree? I need to get that book.

Fixed, at least for now. Pressed a reset button on the keyboard circuit board under the monitor. Now we see it it happens again.

My original post is about all the help I can offer. Its from the instruction manual that came with the lathe.

which book is that? Title, publication number? Is it a Hyundai or a Siemens book? Mine books do not have this error in them.

Again, it is the instruction manual that came with the lathe. The manual has 9 books and one of the books lists the alarm codes. The alarm code book has the following info:

This information is from 1996 so its validity is questionable.
