OK I have FX3U48 MR/ES-A And it seems to stop giving the signal Threw Y7 to start the belt to take the product to another conveyor. The Y7 on the bottom of the PLC connects to the bottom of the 24V relay coil and the top of the coil is connected to the 24V+ of the FX2N 16 EX controller.
The only way I can get the belts to move is if I jumped a wire from the -24V of the converter to the bottom of the relay which makes the belts run all the time. I tried a new PLC New relay replaced the photo sensors tried to reenter the program in to the PLC from another since they are all programmed and wired up the same and nothing seems to work I even ran new cables from the main box to the belts and nothing seems to fix this problem.
Any suggestions?
