CAUTION! If the counter is 110/220v 8 pin, i don't know how to wire since i haven't used it.
if the counter is 12/24v and 8 pin like this on the video:
- power supply 12/24v positive on pin 7, negative on pin 2
- sensor must be NPN NO:
sensor positive (brown) pin 7
sensor negative (blue) pin 2
signal (black) pin 3
- relay out pin 5,6 and 8 NO+NC
- reset pin 1 and 4
If the counter is 11 pin, there is separate supply for the sensor but i don't know the pin-out.
