I am familiar with picaxe and stamp to the point of knowing what they are. I am too old and grumpy to learn more about them.
I know they have great potential for people who want to figure it out. Only cheap and simple for people who have the hardware and understand the chip.
Seems like a lot of bother just to run a basic dump load, battery box fan, or trigger a relay? Another "sledgehammer to crack a nut"?
My circuit is very accurate. The battery voltage needs to be replicated. A test point would introduce potential errors for most users.
Getting the battery voltage is not so hard. Get a 6V spring-top lantern battery, or 4 Ds in a holder. That will be about 6.5V.
Get the 'real' batteries to 6.5V below where the shorting circuit will activate.
Series them for the trigger voltage.
So 59V trigger, 59-6.5= 52.5V on the batteries. (That's 13.125V for each 12V) Should be easy to get them to there for a few minutes?
Then adjust the blue pot until the yellow LED lights.
Typing that, and the 15 second voltage increase, makes me believe 6V hysteresis is not enough for automatic reset. 9 or 10V sounds better.
Removing the charging amps alone will quickly drop the battery voltage quite a bit, the dumping TS-60 will drop it more very fast. The grid is down so the batteries will be loaded(?) dropping the voltage even faster. Could lead to cycling faster than I would want.
Another glitch may be cold batteries, or automatic equalization. The TS60 can decide the batteries need to be 60V or more. If the shut-down circuit is set for 59V, then the batteries will never (automaticaly) get to the voltage the TS60 wants them to be.
Add the unfamiliar to me XW into the mix... and now I have a headache.
Perhaps in the interest of bandwidth we should email, then post whatever it is we think up to see if anyone thinks of potential problems?
