On the FZJ101, the J inputs are pins 3 and 4, the K inputs are 12 and 13, the Q outputs are 9 and 10, the Not-Q outputs are 6 and 7.
The Clock input is pin 14 ( triggers on the low-going edge ). The Set input is pin 11, and the Reset is pin 5 ( both active low, regardless of Clock ).
mhh... dont realy know what al this means. but i read reset pin 5... when i did the measurements today on the FZJ101 and touched pin 5 it woud stop and start again the contactor switched off and back on again.
