2. For each three-wire circuit component on the machine:
a. Actuate the component (e.g., press the Stop button) and verify that the machine shuts
down (as indicated by the operator alarm).
b. If needed, de-actuate the component. For example, release an Emergency Stop switch or
close an access door, so the next component can be tested.
