V1210 V200-18-E6B K-type thermocouple reading 32767

[ToWilli7]

I have a K-type thermocouple connected to AN 3 and am getting a reading of 32767.

  Power is connected to V1 and V2 just in case if its needed. The jumpers are still set at default. I set the HW config so AN 3 is k-type.

Please check jumpers position inside module. If it is correct - please try to disconnect thermocouple from AN3 and connect to AN4 (with correct jumper settings).

If no result - configure AN3 as analog Voltage via jumpers and connect to analog input small battery with known voltage - test via Visilogic is it Voltage readings correct (ADC readings must be adequate).

If yes - replace K thermocouple to another one. If Voltage test is incorrect - module analog circuit is damaged.

Also note this from the module spec sheet:

No-on so far has directly mentioned this, but as Kratmel says, check the jumpers.  Being at default they are wrong.  Default is the small asterisk.  From your wording you appear to think that changing things in Visilogic sets the input correctly, but physical jumper position must be matched as well.

Also make sure that you have 24VDC supplied to the snap in unit where required.

Depending on the snap in there may be 2 or 3 supplied required.

I ended up moving jumper 5 over and it now works. Thanks for the help guys.
