So what was happening ... motor over-load causing a breaker to trip? Or an error signal causing a reset, or partial close-down? Or what?

i think the issue makes a bad signal that causes reset

H'mmm. smile

Obviously (and hopefully), this was a situation that should never occur.

Any alarms to alert the user(s)?

In other words, what was happening to the patient?

OK ... so what's your remedy (solution)? What do you plan to do with this 760 now? think


If you don't inspect ... don't expect.

there is no user alarm just " abnormal restart, EST recommended" displayed.
and as you know after 3 time of this error the device POST PASSED and ....
I opened the screws of the electro-motor and adjust the shaft according to service manual, so the problem is solved.
the device was working 2 hours well, but i will check it tomorrow again.

That makes sense. Medical equipment is usually designed to be wheeled down smooth hospital corridors* and nothing more. Unless you go for military spec. equipment.

My spelling is not bad. I am typing this on a Medigenic keyboard and I blame that for all my typos.

Good Man. Well done! smile

In case anyone else was (is) wondering, EST (in this context) means "Extended Self Test" (rather than Electrical Safety Test).

@Robert:- just for you, the so-called "friction-less piston"; there's quite a lot of interesting stuff on that (Japanese) site, by the way.
