Regarding pump selection - if pump #1 goes down - would changing 4 wires
in the
estop drawer be an option (thus switching #1 and #2 control?).  I'm just
trying to help
accomodate the pump selection.  If you don't think its worth the hassle
then lets
stick to the manual selection at the pump box.  Comments Tim?

Regarding the K8 estop connection.  Do you think its necessary?  Or
should we get
rid of it like I suggested?

Grant,
Yes, K8 is connected.
Pump #1 selected all of the time could be a problem if have hardware
problem w/ pump #1.  If cannot select #1/#2 remotely, then I vote for
continuing manual selection as we are doing now.  Doesn't sound like
much,
but what it means that we could not run a whole pump if #1 doesn't work.
