Table motor overheating

[pazzo81]

I have 82-70 machines with SS chassis, Omega tek with expanders. I have a chassis that overheats the table motor. I have changed all the C1 pins and the table relay. I have also recrimped all the ends for the wires on the table contacts. No other chassis overheats this motor.

Does anyone have any ideas?

hi pazzo81 what condition is the contact in what other things have you replaced in the chassis

[pazzo81]

The table relay and contacts are new. I completley replaced the unit. I replaced all C1 pins and some C2A pins. I tested the rest of the C2A pins to make sure they had good crimps and snug pin connections. The table motor is a Westinghouse with a Solid State switch. That is also new. If I put another chassis in the machine it doesn't overheat the motor. Only this chassis does it. I'm not sure what else is in the table run circuit (chassis side) that is left for me to try. Thanks

interesting have you tried putting the chassis onto another lane

[pazzo81]

I haven't. I like to keep chassis' in the lanes they come from. I think I'll make an exception this time though because I am all out of ideas. lol I'll let you know how it goes. thanks

swap individual parts with known good ones (taken from another lane that has no issues) until the problem moves. Dont assume just because a solid state switch or contact is new that it works too. Ive gotten faulty ones before. What switch are you using?

same hear ive had a few parts like that over the years

This is the second relay I put in. The first one was the AB with new upper and lower contacts. Then I put in a Siemens relay. The motor has a qubicaAMF switch in it. It works fine with all other chassis' I've tried.

Have you swapped the motor with the lane next to it?

Do you have a jumper cable for your motors? Handy to have an extension cord for the motor plugs and easy to make up. Lets you plug your sweep plug into the table motor and vice verse. I plug the sweep plug into the table and run from the SA cam switch. Let the table cycle half a dozen times while feeling it for overheating (or if it cuts out). This eliminates the motor from the motor circuit. Swapping the chassis with another lane will narrow it down to motor circuit or chassis issue.

double check all wires on contactor and make sure they are in the right places. also make sure they go to the right positions in the C1 plug. Two wires swapped could cause this issue. There are diagrams posted on this site to help trace these wires

Im thinking the same, must be some swapped wires there

[pazzo81]

I moved it to a lane that didn't have a solid state switch and it works fine. It only seems to overheat the motors with the solid state switches.
