programmable on off outputs power on value

Post by Blue 12 »

this should be an easy one, If i want to trigger a second fuel pump for example above 3000 rpm, but the power on value is set to "on", does this cycle the pump with key on and shut it back off again quickly, or does it stay running until the motor is started and then uses the rpm to trigger?

I was going to pwm both pumps, but it looks easier/cheaper to just rewire the regular relays to activate the second pump only when needed. (2 bosch 044s are a bit of a strain on the motorcycle charging system at idle!)

You might get a very short pulse, but nothing useful. Set "power on" to "off".

a short pulse may be a good thing to get air out, ill try it both ways and see what happens. as long as it doesnt stay on for the duration of time the key is on and not running it should be good.
