The Track Circuit Alarm Wizard provides a facility for configuring thresholds for track circuits, trained using recent data.
In Centrix R75 the feature evolved from a heavily manual process into a simple 2-step process. The method for threshold calculation was also heavily improved.Prior to this release, the Track Circuit Alarm Wizard allowed configuration of thresholds on a single channel, and required multiple steps to configure the thresholds. This process has been streamlined to allow thresholds to be configured for multiple assets in a single process.
How to use

Once all the alarms are showing Done (with a green tick), you can press Save Generated Alarms to save the alarms.
Manual mode
If you are unhappy with the thresholds generated from the automatic mode, or want to be more selective with the training data used to calculate the thresholds, you can use the manual mode.
To start manual mode, select Manual after opening the Track Circuit Alarm Wizard from the Alarms sub menu.
Unlike Automatic mode, this mode works by selecting a Site and Channel that represents the track circuit, so will work without configuring any Assets.
The training data will be shown, and the initial thresholds will be calculated automatically;
You can use the Cut function to remove unwanted regions from the training data set;
Select the data you want to remove on the graph (click and drag), then press the Cut (scissors) button. The thresholds will be automatically re-calculated.
Click the Reset button to undo any removed data.
