Welcome to our series of PowerCore training videos. This video is called Input/Output menu.
We're at the home screen, so we'll hit the menu button
and enter our passcode. Hit enter and go down to input/output.
We have "Digital Inputs," "Analog Inputs" and "Relay & Digital Outputs."
Digital inputs, hit enter and you'll see Digital Input 1 is disabled.
2 and 3 are set for floats (auto start maintained, auto stop maintain).
Digital 4 is set for low coolant level. Digital 5 is set for low lube oil and Digital 6 is disabled.
You can also set speed set points in digital inputs.
You can have, I think you can have five, yes five speeds. You can have five inputs
where if you activate those inputs it goes to a different speed every time you
make that that input active, or you could use just one or two of them. So that's quite a feature.
So, let's change one, just so you get an idea. Digital Input 1 is disabled. The function
is disabled, so you hit enter and there's a menu in here. Let's just choose, go either direction,
but let's just choose "Fuel Leak" which will be shown on the display if this input goes active.
You hit enter, "Fuel Leak". "Active" is active on a ground or B-. You can change that to be
active on a B+ or you can change it to where a contact opens when you have the fuel leak.
Action for a digital input, not used if it's not a shutdown, itt would be not used like the float
starts up you would have enough use there. You can have it be a warning, a shutdown,
a controlled shutdown which is similar to an auto stop,
or you can pull a relay in with it (you can turn a relay output on with it).
So, let's back up with the back button and go to Analog Inputs.
Analog Input 1 is disabled. So, go to the menu and we have quite a choice.
There's a difference between a resistive sender input for instance and a 0-5V or 4-20mA input.
The difference is if you go down here and choose a Datcon oil pressure sender
for Analog Input 1, you're done because we know what the lookup table is for the Datcon
oil pressure just like we do for the Murphy or the VDO. We know what those look up tables are.
Let's change an Analog Input 1 to a 4-20mA input for gearbox pressure.
We don't have a lookup table for that built into the controller, so at the end of the analog menu
there's a sensor setup. When you choose a 0-5V or 4-20mA analog input this sensor setup appears. You
hit enter because you have to tell this controller what 4-20mA mean. 4mA generally equals zero. 20mA
in this case would equal a thousand pounds. What we know from experience in a gearbox oil pressure
isn't going to be a thousand pounds and you would lower this to what 20 milliamps represented.
That way we're calibrated. We know what 4 and 20 means and we're linear in between.
Relay and digital outputs.
Relay 1, a 10A relay is set for crank, which is a factory default. ECU Enable. Common alarm.
Not used. You can choose from many things in the menu for relay to act on.
As you come down here you see the two 5V outputs
that are not used. We have 2 dedicated 5V outputs on the MPC-20 and you can get in there and choose
what you want for those to be activated on and that's those are actually 5V when they turn on.
Digital output.
Digital output 3 and 4 are both high side FETs for 2 amps. You can select what you want those to be.
The low side FETs are already assigned to throttle decrease and throttle increase for our
mechanical throttle actuator because we require grounds
to be pulsed out for the throttle actuator. So those are already set but you can change those.
Hit the back button, back to the input output menu and that concludes our video on Input / Output.
Thank you.
