2. Pick an unused relay (or relay position) to be used as the enable/disable relay. 

3. Assign the enable/disable relay to the trigger as specified on the table below. The trigger may be set to ON Mode or OFF Mode depending on the logic prefered. If the trigger is set to ON Mode, and the enable/disable relay is ON, the photocell will be enabled.
