Error SEK #15 SM 74-4 1996

Hello everyone, I am having a problem with my SM 74-4 1996 machine, we bought the machine a few months ago, we still could not get it to work 100%, the problem is that the machine blocks when turning on, SEK error #15, we have already moved the cables, but the most notable thing is when testing the locks such as a stop button, doors, among others, in Cptronic it appears that it receives the information but it does not disappear, that happens with all locks. As if you didn't press. We also already had a case of blocking without turning off the machine and enabling it.

hola a todos, estoy con un problema con mi maquina SM 74-4 1996, la maquina compramos hace algunos meses, aun no pudimos hacer funcionar 100%, el problema es que la maquina bloquea al encender, error SEK #15, ya movimos todos los cables, pero lo mas notable es al testar los seguros como un boton de stop, puertas, entre otros, en la Cptronic aparece que recibe la informacion pero no desaparece, eso pasa con todos los seguros. como si fuera que no presionaste. tambien ya tuvimos caso de bloqueado sin apagar la maquina habilito.

  • We removed almost all the main board cables and reconnected them, cleaning them, among others. We do not remove the CPtronic cables.
