TIDA-00637: Pilot Signal States to Verify

Part Number: TIDA-00637

Hello TI...

I am working on 3-phase EV charging station for that I am studying TIDA00637 design guide in this regards I have below queries..

 I am using TIVA series controller TM4C1231, I have generated the PWM signal and given to PILOT circuit OPAM TL082. I successfully generated the +12V,-12V signal.

However, I want to verify the states of EV as mentioned in 4.1.2 in TIDA-00637.

How I can do this??

In the notes it has written that we can apply resistive load my question is

Can I simply use the 2.74kOhm to check its states??
