  If the Alarm LED is on for the RX side of your cias Protection Device, it could be due to several reasons. First, check for misaligned rays and perform the pointing procedure. Second, remove any obstacles present in the protected field. If these steps don't resolve the issue, the Tx or Rx circuit might be faulty and require replacement. Alternatively, the microwave front-end Rx or Tx could be faulty, needing replacement as well.

How to troubleshoot a Fault LED on the Tx side of a cias MICRO-RAY Protection Device?

  To troubleshoot a Fault LED on the Tx side of a cias Protection Device, begin by checking the power supply voltage, as it may be experiencing high or low voltage. Also, verify that the temperature is within the range of -35C° to +65C°. If these are not the cause, the oscillator in the Tx ray may have failed, requiring replacement of the Tx front end. As a last resort, the Tx ray itself may be faulty and need replacement.
