Finally got the pieces that i think i need to get into credit sales. My first Nayak balked at the 28 volts running in my system and never worked. Got the replacement last week coupled with a external stop button,and power converter. I am using a microcoin with a led 6 timer. Nothing else. The wiring diagram for the stop seems self explanatory except for the normally open ,normally closed wires....what do i hook them to? And would i install the pulse 1 to led6 pin 8?
