HOW THE VEND/BY-PASS SWITCHES WORK
SINGLE PRICE VENDERS
1. The Vend Motor and Vend Motor Switches are shown in the stand-by position. (See figure 1 and figure
2)
The arm of the Vend Motor Switch A is in the cam notch (low cam).
The arm of the By-Pass Switch B is on top of the cam (high cam).
2. a. Set up a credit.
b. Make a selection.
(Pushing a select switch causes the vend motor to run and the arm of the by-pass switch drops in
the cam notch and breaks the circuit to the vend relay coil - cancels credit.)
c. The Vend Motor continues to run through the notch.
d. The arm of the Vend Motor switch reaches high cam causing the vend motor to continue to run.
e. A fraction of a second later, the By-Pass switch arm reaches high cam and forms a by-pass around
the Vend Motor Switch. If a jam occurs, all other selections will work.
f. The Vend Motor continues to run to the stand-by position.
SIID VENDER
A. Vend Motor Switch
The vend motor switch, one (1) for each circuit, is located on the Vend Motor Assembly and secured by
two screws.
The normally closed contact of the Vend Motor Switch is in the Vend Motor Coil Circuit. This normally
closed contact opens in the Vend Motor Coil Circuit to keep the Vend Motor running via the SIID
Controller Board, until the arm of the Vend Motor Switch drops in the cam notch and the vend motor stops.
The normally open contact of the vend motor switch has no function.
