It sounds like the LEM was hooked up right.
Possible things to cause overcurrent not to work:
D3 in reverse. D3 bad. R12 not 10k, R15 not 330 Ohm, R11 not 1k, Bad U8 (comparator), U8 in reverse, D8, D9 in backwards or bad, R9 not 2k.
These would be really important: R14 not 750 Ohm 1%, R18 not 3k 1%. Not 500 Ohm pot for VR1.
