Note1) When the wire of thermocouple is broken, the digital value will change to K8000 within 70
seconds. Practice in the ladder program a process for avoiding a risk, would be resulting from a
broken wire, and exchange the thermocouple.
Note2) From the Power-on to the converted data Ready, the digital value will be K8001. Create a ladder
program not to use the data obtained during that period.
