I have a BMN Nitro contoller that I'm wanting to get wired up and it appears they are out of business or their website is not working.

Does anyone have a wiring diagram for the controller?

 

pin 30 is 12v
pin 87 power output to solenoids

 

Is the red wire on the BMN Box constant hot or is it the switched hot from the micro switch?

Pin 30, is it constant hot too?

If these are constant hots then what activates the solenoids?

Anyone know what the setting should be? He is wanting to set it at 3500...

 

Anyone know what to set the setting at?

Want it to come on at 3600 and off at 6700

 

switched 12v

pin 30 is 12v constant

think of a relay as a switch

pin 30 is high current input
pin 87/87a are high current outputs

pin 85 and pin 86 control the switch...if you have 12v and ground on those 2 location you have a connection between 30 and 87...if no circuit is present you have a connection between 30 and 87a.

A relays purpose is to allow a low current circuit to control a high current circuit...this reduces the current present in most of the wiring circuit which in turn reduces heat, wire size requirements, and potential for disaster in case of a short
