As coins are inserted, the changer’s logic board
compares the accumulated credit to the vend price.
When adequate credit is reached, the changer’s
logic board activiates the changer’s vend relay for
250 milliseconds. This energizes the vendor’s credit
relay, cancels the changer’s credit and initiates the
change making cycle if required.
The energizing and latching of the credit relay
removes power from Jones plug line six, which
inhibits the acceptance of coins and enables the
selection switches for vending. The changer’s vend
relay’s N/C contact connects the AC hot line to the
vendor’s credit relay’s N/O contact.
When a selection switch is activated, the vendor’s
vend motor begins to run. The vend motor
mechanically activiates a motor carrier switch which
holds power to the vend motor until the motor returns
to its home position and deactivates the vend relay of
the vendor. This returns power to Jones plug line six
enabling the acceptance of coins.
