TC120 CJ Temperature out of range

Here is my problem.  We have 5 TC-120 install on the cFP. They are on module 4 to 8. Using MAX, for module 4, the CJ temparature is 223- out of range !. For other module, the CJ temperature reading is 295.5 etc. So we swap module 4 and 5. Just to see if the TC120 on module 4 is working or not. Again, using MAX, it read CJ temperature on module 4 still 223-out of range ! All other module CJ temperature reading give 295 ! Look like the TC120 are O.K but the chasis ?
 
Thanks in advance.
 
Appreciate for all the help.

You say you swapped the modules.  Does that mean you swapped the TC120 module or the CB3 isothermal blocks?  The CJC thermistor is located on the isothermal block.

Thank for the replay.
 
First we swap the CBC block module. It still inticated that CJ Temperature reading of 223. Then we swap the CBC back and swap the TC120. Still, nothing work !

Hello,

I suggest that you call in for support on this issue at 1-866-275-6964.  You can also generate a phone service request online at ni.com/ask.  It may be easier to get an engineer on the phone for this one to help determine if there is a problem with the hardware.

Take care!

Dear Field Kam,
 

                         Thanks for the replay. Unfortunely for me, my 'support service' expired. I was told that I need to 'renew' my support service. As for now, my customer order another cFP system (they currently have 5 sets). I will wait until they got the system and call in for help ( I should have 30 days of hardware support).
