Input connections
The START, STOP, REST TO ZERO and RESET TO PRESET inputs are on a small pcb on top of the
main pcb. The voltage between the EX+ and GND terminals (5, 12 or 18VDC) is determined by the
setting of the
P.Out
function and these terminals can alternatively be pulled down to ground by the
PULL UP
function.
