SOLAR RADIATION SENSOR INSPECTION

BHE074061751W02

1. Shine an incandescent light (approx. 60 W) directly on the solar radiation sensor from approx. 100 mm {3.9 in}.

2. Using a tester, connect the positive (+) lead to solar radiation sensor terminal A, the negative (-) lead to terminal B and verify that the output voltage is approx. 0.45 V.

  • If the voltage is not normal, replace the solar radiation sensor.
