I am a relatively new owner of a 1987 Quick Turn 10N. I got it a few weeks ago and it was packed with chips and really dirty. I powered it up to start with to ensure that it had made the move ok and everything worked fine. This Safety switch (on the back side of the machine) got moved to the on position during the move and caused fuses to blow until it was moved to the off position.
After a cleaning for a couple of weeks with it powered on and off I got a #9 alarm (Detecting No Signal X) and heard clicking coming from the rear cabinet. I powered down the machine and disconnected the power completely so as not to trip the safety switch. The cabinet was very clean inside and nothing looked out of place. I was really impressed with this 35 year old machine.
When I reconnected the power and turned on the main, all of the fuses blew. I have looked through all of the manuals that I got with the machine and can't find any mention of this switch or its function. I suspect that it causes the 3 phases to go to ground so that you can't go into the cabinet when it is energized but I am not sure. Maybe there is a specific sequence that I am not following.
So, can someone explain how this safety switch works and how it should be set? Also, if you have any other ideas of why I could suddenly be blowing fuses or what the source of the #9 alarm is, that would be appreciated also.
To clarify on the switch, turning to the left is 'Off' and to the right is 'On'.
Thanks in advance.
