Device Moisture Sensor Bad Reading Alert

Updated June 22, 2026 1 min read

Device Moisture Sensor Bad Reading

Priority: High

Definition: The Controller is unable to get a valid moisture reading from the Moisture Sensor

Example:

When this occurs, the controller cannot communicate with the moisture sensor thus it can’t get the information from the sensor either such as temperature or moisture readings. This can impact your programs running if they are assigned to the programs. 

This can also be seen as a two-wire communication alert.

Commonly this alert is caused from damages in the field such as damaged wire splices, corrosion, poor splices, damaged two wire path, or water filled boxes with poor splicing. 

Action Needed: This is an alert and action 

Troubleshooting:

-Remove the sensor and test the sensor at the controller to narrow down if it’s the device or a field related issue.

-Replace the splices with DBR/Y-R splices according to specifications

-Isolate and repair any damages in the two-wire path
