5 amp fuse...the next question where
to find a 5 amp fuse for 36V. You can find millions of 5A fuses
for 12V, but a 36V one is going to be hard to come by. Trial and
error with varying 12V fuses might work...but it's going to be a
real pain trying to get that to work. If the fuse is hooked to
the field, and it goes over 5A, then the fuse blows.......how is
that going to turn off a relay or contactor? If you ran the field
though a relay or contator coil...well, you're asking for
trouble. Now you have the drive motor field and coil field that
you need to think about...some coils don't like sharing power with
other things.
Personally I would not put a fuse on the field. A small SepEx
controller would be the best option, but barring that I would hook
a relay going to the field to the micro switch on the PB6. (If
you are using a foot pedal) When you touch the pedal the field
comes on long before the armature gets power...unless you stomp on
the pedal. So power (+) goes to the microswitch, to the + on the
field relay coil, to "-". (Although I can't recall if there are 3
pins on the microswitch or 2)

This is a question to anyone using a non-alltrax controller that
is not using field weakening (36v straight to field)... It is my
understanding that the field should use no more then 5 amps.
Please correct me if wrong. I have looked at quite a few ckt
diagrams for different controller installs and do not see any
fuses on the field. Has anyone installed a 5A fuse on the field
ckt? I am thinking of installing such a fuse, which if it blows,
will turn off my solenoid killing all power to controller. Does
this make sense? Am i being over cautious?
