Xray on de move, wit de fault.
It reminds me of a riddle I used to ask my kids.
Make a 12 word sentence with these words. Defeat, deduct, defence, detail.
Answer: De feet of de duck go under de fence before de tail.
Honestly, I thought it was clever, even if the kids thought Dad had lost it.
This time, I had a mobile xray machine (xrays on de move) that had a drive fault (de fault). What a cow of a problem this was!
Turn the key, press the push bar and the machine would trundle away quite happily. After a while, it would hiccup, splutter (metaphorically) and roll to a stop, throwing up a Drive Fault message. The machine is very heavy as you would imagine. It carries a series of batteries, like car batteries, an xray generator, plus big drive motors to move the machine around.
Looking through the service manual gave some clues as to what the problem might be, what sections of the machine to look in and some tests to try.
None of this information was any good. Drive Fault error.
Fortunately, there is an identical machine in de hospital (oops) so I could swap parts between machines. The problem was in the push bar. It has miniature sensors that detect push pressure. That tells the drive logic to deliver battery power to the drive motors.
The push bar had been pushed one too many times and caused the sensors to fail.
A new push bar and presto, xrays on de move, widout de fault.
Next, a tale of flash and bang.
