DN 501E dispenses 2

Recommended Posts

Been lurking for a while and finally need some help. I have an older live display 501E that has been working great. I recently started having an issue with 1 slot where I have Gatorade. The Gatorade dispenses but when the slot comes back to the motor switch arm the arm goes back down and the motor continues until the next slot. On its way to the next slot it dispenses a 2nd Gatorade. I know the camb is set correctly and I have replaced the motor switch. I have completely removed the entire assembly and don’t see any issues at all. I have a gif that shows it happening.

Any ideas?D509B84A-1F43-4EDE-9403-429CB4D395AC.gif.60926ce7461fbe91a6d4f737e1e59b79.gif

The motor switch is bad.

Maybe I am confused on my terminology but I have already replaced the arm on the bottom of the cam which I believed to be the motor switch. The same thing is happening with both switches.

The metal piece is part of it but the entire gray piece with the two screws holding it is the switch.  You need to replace the gray part but you usually buy a "motor switch" which includes the metal arm.

If you did change the whole thing already, then try unplugging the power to the motors and clean the brake (metal part above the cam that BARELY moves slightly up and down as though it's loose).  If it's sticky, even a little, it will allow the motor to run.

It looks like the switch arm might be too deformed to disengage the switch.

Then the harness might be broken.

Thanks for advice. I did replace the entire switch. I will work on cleaning the brake. Any idea what I should use to clean it with?

The motor does stop it just doesn’t stop where it should. The brake sticking makes sense.

Clean with windex. DO NOT LUBRICATE.

Lube will become gummy and sticky in the cold and attract dust.

Looks like you installed the metal lever on backwards? All my motors has the it the other way? did you deform the metal arm after you installed it backwards?

Correct me if I'm wrong.

The motor switch in the gif is a replacement ordered. After I determined that wasn’t he problem I put the original one back on. That switch lever is different than the ones I had. 

On a side note I cleaned the brake release and it appears to be working correctly again. 

Thank you for everyone’s help.

That is a wrong switch on your motor.  It should have just a 90 degree bend at the end.

You are right! I didn't notice until you mentioned it. Looks like a Vendo switch.

That is a Vendo door selection switch from the Univendor 2 series and some Vmax doors.

I thought it was odd. I sent it back to who I purchased it from.
