dogcow Posted March 9, 2011 Share Posted March 9, 2011 having a problem with a dn368, its been vending 2 cans, then nothing for 2 cycles then 2 cans again. i've attached a picture of the cam settings the one on the far left is the one with problems. it was previously 16.9oz water and i reset it for cans (all cams pictured should be set for cans), i thought i set it right and it seemed to be working right but i got complaints from the location. any thoughts?

Technivend Posted March 9, 2011 Share Posted March 9, 2011 The picture on the left is showing 3 valleys on the cam. This should make the machine drop one, nothing, then work right for 2 more vends then nothing. I would start by setting the cam the same as the picture on the right. Any chance you have taking the motor out or removed the cams from the motor? It is possible to put these in 180 degrees off. Link to comment Share on other sites More sharing options...

Technivend Posted March 9, 2011 Share Posted March 9, 2011 Cam should be set in position 3. Rear spacer set in hole 19 as per Dixie http://dixienarco.com/comSite/CustomerService/PackageSetups/tabid/164/Default.cfm Valley meaning the notch that the switch falls into to stop the motor. Your video shows the switch fall into the valley that shouldn't be there and stop the motor prematurely. The product should vend on the next try as it needs to turn more to complete the cycle.

NinnJinn Posted March 9, 2011 Share Posted March 9, 2011 The column that is double vending, is it a single stack? or is it a double stack? Link to comment Share on other sites More sharing options...

Technivend Posted March 9, 2011 Share Posted March 9, 2011 If you look at the holes on the brown cams you will see they are numbered. The hole with the 3 is where you want to be/ Link to comment Share on other sites More sharing options...

The hole with the 3 is where you want to be/ i adjusted the cam settings correctly but it is still vending 2 cans , then none, then 2 cans again heres the cam settings, the left one is the problem column, the one on the right is functioning correctly heres a view up from the delivery door, the empty column is the one which isn't working right Link to comment Share on other sites More sharing options...
dogcow Posted March 16, 2011 Author Share Posted March 16, 2011 here im triggering the switch manually of the malfunctioning column, maybe this video will help in diagnosing this video is different from the last, because its taken after i corrected the cam setting Link to comment Share on other sites More sharing options...

Technivend Posted March 17, 2011 Share Posted March 17, 2011 All I can see in the pictures is that the Dr Pepper looks like it has a small metal shim and I can't see if there is one in the empty column. If you could take a video from the underneath of the vend cycle, that may help. Also maybe a picture from the top with the good column and bad column, both empty. If all you setting are correct you could have a bent sidewall or twisted rotator cup. To check this you would remove the cup and check both with a straight edge. Have you tried swapping motors out with another column? If not try this and let us know what happens. If it stay in the column it is mechanical, it could follow the motor if the motor is drifting a little too much.

I highly doubt it is the rear spacer but anything is possible. There are so many variables in a machine that what is working in one column should be duplicated in a non-working column. To swap the motor, makes sure the motor cams and rotor are the same in the machine, unplug the machine, remove the wires, remove the 4 screws, pull the motor forward while holding the rotor, mark the rotor with a marker. It isn't hard, just be sure you have agood screwdriver that is the right size. The screws can be stubborn. Link to comment Share on other sites More sharing options...
