Chassis

[Scruff]

I have a chassis which has no sweep run or sweep reverse from the managers control. Have tried changing boards, tried chassis on other lane, still don't work! Can any of ya's help me find out where the problem may lay?

Re: Chassis

does the sweep run using other methods(cycling machine etc)? or sweep doesnt run at all period?

Re: Chassis

Scruff,

1. Check your c1 & c2 pins and sockets
2. Check your fuses or cb's on the chassis.
3. If you have and omega board make sure the ground wire is hooked up & the little #3 board is in also.

Re: Chassis

MY sweep operates normaly in cycle and can be run from the Sa also. It just won't operate from the backend control. I have checkd all of my c1 & c2a pins etc, and all seem fine. [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img]

Re: Chassis

have you replaced the switch

Re: Chassis

Yes I have replaced the switch, that was one of the first things I tried. It is definantly in the chassi. I have narrowd it down to that.

Re: Chassis

it has to be

faulty c1 plug wire/pin or
broken joint on contactor

physically pull each wire, to make sure its not broken, and then meter each wire for continuity.

Re: Chassis

Scruff,

Sounds to me as if it's in your low voltage circuit since everything else is normal. Check the wires and pins from your C2A plug to both switches.

Also do you have a relay in the mechanics control box?

Your sweep run switch over rides almost everything in the PCB and is the same as a direct ground to the relay itself which of course will energize the relay unless you get the other side which will trip the CB.

Re: Chassis

I don't have a reley in the control box. I am currently going through my C2A plug and checking all the wires now. It is definantly in the chassis it self, and if it aint in the C1 or C2A, well then I'll be buggerd if I know!

Re: Chassis

scruff, i'll be coming through geelong, on the 27th-29th, i'll pop in and see if i can help you out

Re: Chassis

One side of the switch goes to ground in the chassis. Its grounding point is the same as SA,SB,TA2,TA!,etc. etc. so that side of the circuit is good because your machine goes through a cycle ok.
The other side of the switch goes to the #3 board connector socket on the motherboard in the chassis. It goes there so it can bypass all the electronics in the chassis by going through the switch when you activate it.
Most likely you have a loose or open connection somewhere between the C2a wire and the #3 board socket. The wire is C2a-21 and is on the third row down from the top and is the wire on the end of the row closest to the foul line. Follow it to #3 socket terminals 28-29. Terminal 1 of the sockets start closest to the table and sweep relays. Re-solder also.
