Re: servo brake problem

Doug, I am not sure how the brake works. There is a solenoid that
is air activated, but I do not know what the solenoid does. The
other two solenoids positioned next to the brake solenoid are
functioning and allow air to pass through to affect a spindle speed
change. I assume the air pressure is required since the brake
releases when I disconnect the air line. My problem is turning off
the brake without having to disconnect the compressor. Does that
shed any light?

thanks
