[ausev] Scott's Conversion

[Wieser Scott]

Hi Rob,
 
I talked to KTA about your hlll/high lock problem.  They claim to have
solved this problem by installing a small relay parallel to the large
contactor.  The relay operates much faster than the contactor and
supplies the controller with input fast enough to prevent the problem
you describe... makes sense to me.

I have a Curtis 144 VDC system too and it's been working fine for me.  I
have 2 fans and the controller seems to manage the summer heat.  I can
pull >400 amps when needed (my ammeter tops out at 400).  I'd like to
have more instrumentation from it and the low speed stall whine is a
little distracting at times. 

My chief complaint has been caused by a combination of pedal safety (-
contactor opens when foot is off the accelerator) and the high pedal
lock.  I can press the accelerator faster than the contactor closes and
that means the controller thinks that I've got a high pedal and won't
start.  It's a pain, but a good safety feature that's only an issue
starting on hills (not many around here ;).  I added an override button
and that is working so far.
