AERONET Instrument Troubleshooting Interface - Solutions for SENSOR HEAD CABLE COMMUNICATION ERRORS Flag

Description
The sensor head is connected to the control box via a multi-conductor cable that carries both power and digital communication signals. If this cable or its connectors are damaged, corroded, or not fully seated, communication between the sensor head and control box can fail, interrupting measurements. These errors frequently co-occur with robot errors or filter wheel errors when the root cause is inadequate 12 V power rather than a cable fault specifically.

Solution Level 1 (< 5 minutes)
Typically, errors will not occur if you can successfully read out the temperature.
1. Check/reseat the the connector panel and both ends of the sensor head cable.
2. Ensure that adequate 12 V power is being supplied to the instrument.
Sensor cable errors in conjunction with robot errors often indicates a problem with connections or 12V power.

Solution Level 2 (more involved)
Model 4 and 5:
1. Check/reseat internal connections. See Internal check control box.jpg
2. Try a different cable and connector panel (if available).

Model T:
1. Try a different cable and connector panel (if available).

Solution Level 3 (last resort)
1. Return instrument for maintenance.
