Wiring Auto Tool Zero & Touch Plate


Staff member
There is conflicting info in the MASSO documentation about the size of resistor required to connect either ATZ or TP.

On the web site the wiring diagram for the ATZ is missing.

The TP page shows a 5.6K resistor.

In the downloaded pdf v1.19 it shows both ATZ and TP using 1K resistor.

So the question is which one is correct?

thanks for bringing the missing image to our notice and we have now fixed it.

The 5.6K resistor value should be fine, but it also depends on the voltage you run the MASSO on. So at 24v, 5.6K value is good.
