When the timer button is pushed, the lower circuit is activated. The basket lift lowers,
closing the normally open upper microswitch. The motor loses power when the basket
lift rod moves down and opens the lower, normally closed microswitch. When the timer
times-out, the upper circuit is activated. The basket lift rises, closing the lower
microswitch. When the rod clears the upper microswitch, it opens and power is again
cut to the motor. Pushing the timer button again restarts the cycle.

To computer/controller
via interface board
When the product button is pushed on the computer/controller, current flows through
a coil in the basket lift relay. The lower circuit is activated and the basket lift lowers,
closing the upper, normally open microswitch. The basket lift rod moves down,
opening the lower, normally closed microswitch and removing power from the motor.
When the computer/controller times-out, the relay coil loses current and the upper
circuit is activated. The basket lift rises, closing the lower microswitch. When the rod
opens the upper microswitch, power to the motor is lost again. Pushing the product
button again restarts the cycle.
