TPT error - response (10) by tt255009

Hi,
 
I am trying to LOAD a table with the following TPT scripts.
1.       ErrorLIMIT1 = 5
2.       ErrorLIMIT2 = 5
3.       Maxsessions = 1
4.       Minsessions = 1
5.       Loader_Instance = 1
I have a file with 10 UV Values for a single Key value e.g., for primary key = 2 there are 10 UV records. I expected TPT to fail but it did not. Can anyone explain this behavior? What is the scenario in which Errorlimit is used by TPT and it fails.
 
Thanks
