Is anyone familiar with this alarm on a TM-1? It was unaccompanied by any other alarm and the machine was just sitting at the time, had been drilling and tapping into 6061 alum earlier, nothing strenuous. I've called the HFO and set up service, but I have a rush job this weekend, working OT and would like to run the LH parts on one and RH on the other. Is there anything I can check until the srv people get here next week? Details: reset cleared conditions with a loud click, I removed tool holders from machine, no orientation problems etc. After a couple of minutes of watching it I heard a loud click and it alarmed again so I shut it down and killed the main.

Thanks
