MPM up500 smema issue | 31 August, 2016

I have a smema conveyor connected to the downline fmi connection on my up500 but the fmi sugnals show the coneyor ready signal going ro the upline ready input (screenshot). The downline ready output is activated qhen a board is output from the printer and waiting to transfer to the conveyor. The machine doesn't transfer because it doesn't get downline ready input. Tried connecting conveyor to upline fmi port on printer but then no inputs are activated. Machine is setup for l to r flow with right initialization selected. Also after about 90% of prints the machine says "pcb did not unload" but it is at the output conveyor and is unloading.

Any ideas?

Some of the MPM machines have a SMEMA configuration in the software. Not sure about the UP500.

Yeah, it's set to use SMEMA for down line. I have the conveyor conected to downline fmi on up500 (right side of machine,) but the Upline Ready light is activated on the up500 when the conveyor is ready and not the downline like I would expect to see. Tried connecting the conveyor to the other port (upline) and I don't get any signal from the conveyor shown on the up500 inputs. I do think it's a configuration issue some how though.

If you force a signal (hardware short across Pins 1>2 on SMEMA end of cable) does it indicate downline available?

Looks like I've got to reconfigure the fmi connections. Only pins 1 & 2 populated and when I jump the fownline pins the upline ready signal is activated. I'll reference the diagram and setup the connections for smema.

"Fuji" interface?

It does look like it was setup for fuji or siemens connection. I did get the smema signals working; had to add the connections for pins 3 & 4 on both ports and move some of the existing connections according to the smema diagram. Also, I wasn't seeing any downline ready signal and found that a jumper was removed in the Master module preventing the signal from working. Installed the jumper and smema works with my downline conveyor.

I still get the message "board did not unload" even though it outputs on the printer conveyor and transfers to the downline conveyor now. I have checked all of the printer's conveyor sensors and they all respond in the diagnostics and adjustment seems ok so I'm not sure why I still get that message. It's annoying because the transfer system has to be 'initialized' before eevry print so I'm unable to use a board loader until that is resolved.
