l mode.
The mode of operation is determined via
the position of a jumper on the main control
board.
The controls are shipped with the jumper in
the J1 or single mode position. A variety of
output logic can be accomplished via the
single/dual jumper position and whether the
control is wired to one input switching
device (2-wire mode) or two input switching
devices (3-wire mode). The following
diagrams show how each channel (output)
of the control can be either alternately or
simultaneously energized.
