Green Constant
When you set a sensor input to "green constant," the sensor must turn on before the ready
signal begins and turn off after the ready signal ends. That is, it must stay actuated constantly
during the ready signal. However, the sensor must turn off, at least momentarily, outside the
ready signal.
