When Tracker expansion boards are used with the system to control up to 16 additional entry points,
relays 1 and 2 are designated as tracker command relays and connect to the Tracker expansion
boards. In this diagram, relay 0 is used to control the gate operator and relays 1 and 2 are connected
to the tracker expansion boards. The relay 2 shorting bar is set for normally open (NO) contacts.
