On the Generator Unit PC 080 there is a connector on the pcb , marked
as J 501 . It is a 5 pole receptable . On it there is plugged a 4 pole
plug and you can put it in the J 501 in two way's . But .. what is the
purpose of this connector ? On the 4 pole plug there are 2
connections , pin 1 and 2 are connected and also pins 3 and 4 . But I
do not know what this plug does . Is there anyone who can help ?
