If you are trying to connect a 2 wire sensor to a 4 wire card, see picture for connection. Regards, Marcjan Attachment 2 wire.JPG (241 Downloads)

Give us all the details how you connect the sensor, i.e. to what pins, other channels connected or bridged? A picture of the cover (with connection details would be nice too. Regards, Marcjan
