Here is how smema works: Machine A has a board to give to machine B. Machine A has an opto or a relay that will turn on or close when it is ready to pass this board to machine B. This is the "board available from previous" signal, telling machine B

Dilbert, You are both right! Just above the schematic in the Smema standard it says: "Conformance to the standard may be achieved by the appropriate design of the equipment or by providing special adaptors which enable the equipment to meet the stand

that sounds like bad relay or relay control. are you in position to check it on relay pins? I would go from there.

Switched out the mech. relay on the board loader, no change. Same behavior. Could not find a mech. relay on the printer... SMEMA wiring appears go directly to a PCB. And it is at that point that I run out of talent. If the machine weren't dedicate

Is the belt tension right? Are the axes tacho - acceleration right? On the F5 with output conveyor problem seems to be K2 relay problem. If you are open-closed the door (stop and restart the controlling) helps, the K2 is the problem.

Mike, Another thing to consider is the type of switching they may use. Older Asymtek masking machines used transitors to communicate upline and downline instead of dry contacts. The problem we had with this is dropping enough voltage across them to

It's been a long time since I did this. I think if you get a cable (maybe from some of the used equipment dealers that advertise here) you will still need to change the contacts of the relay the Fuji uses. I think they use a normally closed set of
