- If turning on the power correctly shows ~12V, but shows a small current draw (~0.4A)., or if the detector screen shows "ERROR":
Power down the power supply. There are two power cables connected to the red power supply. Unplug both of them at the outlet (not at the power supply).
Plug back in the power supply chord first. This is the one with the white 3-pronged connector on the power supply side. Then plug in the controller power chord. Once an orange light turns on on the controller, flip the controller switch up. You should now see a green LED light up under the orange light.
- If the temperature/humidity stops updating .and/or reads very bad values:
Restart the JF4M Detector IOC. This usually reconnects the IOC to the arduino. the Arduino (and therefore the environmental sensors). If this doesn't work, try power cycling the Arduino by disconnecting the USB cable from the hub on detector rack 50. <attach picture>
