Pressure Switch Wiring Question

[Matthew_H]

How are we suppose to wire the cable for the pressure switch to make the compressor turn off. Do we use PWM cables and if so what is the pinout. I am also unsure of how to code the pressure switch in the new controller. Please post your ideas. Thanks

you need to get the FRC (full size robot controller) user manual from the innovationfirst web site - it shows the pinouts for the digital inputs

and if you look at the default code I believe there is already a digital input pin setup and a relay output that will run when the pressure is low, and shut off when its high

use the grey wire that came in the kit, the thin one - I forget if it has two or three wires in it - and cable it to the signal and gnd pins of the digital input on the RC. The on/off sensor is the one with the two screws - and it doenst need power - its an on/off switch inside.

The default code already has INPUT 18 assigned to the pressure switch, and RELAY 8 assigned to a SPIKE relay per say that would be wired to the compressor.

We chopped up a PWM cable and wired it to the gray cable that was in the kit. Works fine.

I'm not sure if it's the same as last year, but the judges made up re-wire out pressure switch to the digital outputs before we could participate.
