is there anything special you have to do yo use the cooling fans in c++ of can we just hook them up the the power distribution board?
You can connect them separately to the Power Distribution if you wish, but:
<R55>D The supplied fans attached to speed controllers may be powered from the power input terminals.
is we hook them directly up to the power board they will just run on full power right?
is that a good idea or bad
I think Alan is saying that it is overkill to connect the fans to the power board. The fans are not required to have a dedicated circuit with a breaker. You will already have 12V (2 wires) coming from the power board to the V+/V- terminals on the victor motor controller. You can connect the wires for the fan of each victor to its own V+/V- terminals. The fan will run full speed all the time whether you hook them up to the power board or the V+/V- terminals.
so we can hook them up to the victor or the jaguar?
The cooling fans mounted on the victors can be powered from the V+/- terminals on the Victor. The Jaguar fans are terminated internally.
If you are installing seperate cooling fans from the provide KOP muffin fans, you could install those with power directly from the distribution board or from a spike with a PWM output. I would only power from the spike if you felt you needed to cycle the fans on and off.
When we have used the muffin fans in the past, we have just had them wired straight to the power distribution board.
Oh! Which fans are you thinking of?
There are small fans mounted on the Victors. Those are the ones we’ve been talking about. The suggested way to wire those is to connect the blue and red wires to the Victor power input terminals.
There are small fans already built in to the Jaguars. They take care of themselves and you don’t need to worry about them.
There are also some additional Victor-sized fans and a couple of much larger fans in the Kit of Parts. Is that what you’re asking about? You can connect them to the output of a Spike if you want to be able to turn them on and off using your program. You can also connect them directly to a 20A branch circuit from the Power Distribution board. I wouldn’t recommend any other options.
