And what can I do about it?
When you have a sensor that is addressed wrong on one of your sensing cables, it can cause some issues. The sensors are traditionally organized so that address 1 is at the bottom of the bin structure, and then programmed in order ascending up from there. If they are addressed improperly then they will report data from other parts of the bin structure that is not representative of the actual location of the sensors.
This is particularly a problem when the misaddressed sensor is located in the headspace area but our OPI Blue system thinks it is in the grain mass. This can cause false high temperature alarms to be raised and confuse the end user.
The above screenshot shows a bin structure with one sensor that appears to be presenting a hot spot in the bin structure. However if we look at another snapshot of this bin when the ambient temperature is cooler, the temperature at this sensor is much lower.
This is because, while this sensor is addressed as "S3", it is physically located much higher in the bin and should be addressed in the teens. Take a look at the chart view of this cable on radius A angle 245 showing S1 which is in the grain, S3 which is reported as in-grain but is actually one of the sensors not in grain, and S19 which is in the headspace area above the grain mass inside the bin structure.
As you can see, S1 is in the grain mass and has no temperature changes in 1 week. S3 which should be in the grain mass is behaving exactly like S19 which is not in the grain mass, indicating is is misaddressed.
At this point the only thing that can be done is replace the sensing cable (or sensing cable element if it is a temperature only cable). Contact your dealer to order a replacement cable as needed.
