Machine not setting pins

[Casey]

I have a machine that periodically decides not to set a rack. Bin switch is good, Shuttle Solenoid is good. It must be a wire in my c2 plug or corresponding wire in my chassis? Anyone know right off the top of their head which pin/wire i'm looking for? I'm not at work...no schematics in front of me and I don't work for a couple of days....Just wanted a heads up before I get back to work.

kinda sad that I feel the need to check in here once in a while on my days off.

thanks

Re: Machine not setting pins

Well before wiredigging, I have a quick question for ya...

You said the binswitch is good, and the solenoid is ok...

How about the SP Relay?

Whoops failed to mention that....SP relay is good too. Tried two different chassis on that machine.
You can jiggle the C2 plug and get the machine to set a rack.

What exactly is the machine doing/not doing? Is the sweep waiting at 270 or is the table short stroking to respot height and returning to zero?

Check C2 for wires of:

--BS
--S Relay
--SB Cam (responsible for firing S relay at 186 degrees)

In wireway on MP machines, there is a capacitor on the BS circuit so the Chassis can read voltage better. Make sure it's there.

Re: Machine not setting pins

If your machines have some age on them the cable from the bin switch from the wire way has a history of going out on my machines....just wire tie some 14ga wire together and crimp tool some female spade connectors and your machine will probably be fixed.

I would also replace any bad sockets/pins in the chassis plugs.
