When installing the switch driver, it is imperative to know which wires will
cause an OPEN or CLOSE condition on each switch.
• An OPEN condition is defined as the black wire from J1 pin 1 is
active-to-common (+ 24 Vdc red wire).
• A CLOSE condition is defined as the white wire from J1 pin 3 is
active-to-common (+ 24 Vdc red wire).
