Hey Guys a little help would be great;;

Replace a 6300FX3 board with a 6300PY4. replaced the software; changed the jumpers (mistakenly had one jumper in the wrong position thru line in still on INS)
corrected jumper; Diagnostics says "Defective Door Board or no door bd present"

power supplies appear good, P150, PV5, on IN have LED 150 on, PV5 on, no LED WD next to PV5, Jumper J1 on, J2 off, J3 off, J4 on;

Cannot move door via manual door open/close on operator.
Cleared door parameters, placed car on Auto no door cycle/ relearn.

what do yu guys think? thanks

hoistway learn OK car will take off. no doors

did the py4 not come with software?
are these two boards compatable for the swap?
no WD...no workie.

I believe P24 ties to board in different locations. Make sure you have P24.

Also
I believe there is an additional cap assy that should accompany that board swap. PN 238CW1. Your board is an replacement that will work.

Thks
Found the problem was no need to swap eeproms.The orig. did not work with the new board.
