Do you have a question about the FDS303 and is the answer not in the manual?
Questions and answers
Good day! Our FDS 303 has steady yellow light and fault indication on our FDS System. I already restarted it by switching off the 24VDC power supply, but nothing changes. What must be the fault of this sensor. Thank you
A steady yellow light on the Micropack FDS303 sensor indicates an internal fault. A red fault alarm is also present in this condition.
This answer is automatically generated
Can I do something about the fault or should the sensor be replaced?
