5 5  If an analog photocell (i.e. a 3-wire 0-10V photocell, not a Cresnet or internal occupancy sensor photocell) is defined in the ShowRunnerCLC™ configuration but you are not receiving a reading when looking at the photocell in XPanel or running the sr show photocell command, perform the following troubleshooting steps:
