You can either ensure that PSCN is never sparked when the EMP activates, or use a correctly positioned CONV to sub-frame convert BREL and NTCT back into PSCN.

 enganK is correct, I reversed engineered a eraser and it had those, I recommend alot of layering and the use of EHOL

you can use conv tmp brel ctype pscn

 A better option is to sandwhich the PSCN wire in between two lines of CONV(PSCN) with a tmp of SPRK and a tmp2 of 1 so that it converts anything except SPRK into PSCN.  That way, both the resulting NTCT and the resulting BREL are converted back into PSCN.
