To use the SOURCE wiring mode, remove the jumper between the +24V and the OP terminals. Connect +24V
to the common port of the external controller, and connect the OP terminal to the COM terminal. If you intend to
use an external power supply with the SOURCE wiring mode, remove the jumper between the +24V and the OP
terminals. Connect the external power 0V to the OP terminal, and the positive side of the external power +24V to
the corresponding DI terminal via the contact on the external controller.
