    Limit Switch Check

    Hello All..

    Making progress on the Thermwood retrofit. Had a quick question regarding the limit switches which are NPN.
    As I understand it I am to place a resistor across the positive contact and sensor contact of the sensor and then running ground and sensor back to the KANALOG board. Is this correct? What value should the resistor be? I've attached a pdf of the schematic.

    Any help greatly appreciated.
