  If the Danfoss Accessories sensor displays a yellow light, it could be due to several reasons. First, check the wiring if the AO is configured but not connected (especially for 0 – 20 mA output). Second, ensure that the sensor type matches the DGS specification by verifying the gas type and measuring range. Also, check if the sensor is properly connected to the printed circuit board. If the sensor is damaged, order a replacement from Danfoss. Finally, check the power supply to ensure the supply voltage is within the correct range.

What to do if the zero-measurement drifts on Danfoss Accessories?

  If the zero-measurement drifts on your Danfoss Accessories, it's because the DGS-SC sensor technology is sensitive to the environment. All ppm measurements below 75 ppm should be disregarded, and no zero-adjustment should be made.
