We have Honeywell's TDC3000 DCS in our plant... Recently we have observed too many noise counts in the UCN... The counts are observed in all the nodes.... We have in all 08 UCN nodes... (9,10,15,16,17,18,19,20 resply)... The Ground resistance is around 1.6 Ohms... All UCN taps are properly tightened... Cables are properly fastened to the LM modules of PLC... We isolated on LM which was giving a higher noise count rate and switched off the LM completely... Despite that the noise counts are increasing unabated... If anyone has come across such a problem, may please share information...
Thanks and regards
