LFS 10 M 2SP: 4702 - 3 Start Inhibit
I'm a little bit new to this machine and Okuma control in general so I'm having trouble shooting this alarm.
It is a 2003 LFS 10M -2SP OSPE100L
I was running programs just fine, with the robot but now the Left side spindle says:
4702-03 and the "I" key says
3-> Start key is pressed when chip conveyer operation mode is not auto mode
My chip conveyor only has FWD, REV, Stop keys on it physically. I've tried all the User parameters on or off and every combination. I've also tried to start the machine with the conveyor on and off.
I'm pretty stumped trying to figure what actually triggers this alarm. I don't recall giving the machine any different command and I don't see anywhere in the M-functions to turn this on/off.
I'm pretty good in a Fanuc ladder but lost here.
Thank you in advance.

1. Yes, ask Okuma representative.
2. Check the chip conveyor - OSP connectivity. Maybe testing all the lines with a multimeter reveals the problem.
3. Hire somebody to draft the wiring diagram for this connection. It is must have anyway.
4. Check once again and double check the point "running programs just fine, <...> but now". Maybe something happened?
5. Check the chip conveyor signals if they react to control switches on/ off
6. Double check the power supply for the chip conveyor control.
