# Alerts There are 4 types of alerts available in the vibration use case. These are visible on the detail view of the device and in the alert tables throughout SolidRed. ### Vibration Severity Alerts Vibration Severity Alerts are based on the machine alert thresholds that can be edited by clicking on the pencil icon next to the item in the detail view. By doing so, a pop-up window will appear where the user can select which alerts to set on the device.

Machine alerts screen

From the dropdowns, the user can select pre-defined options based on the ISO10816 or add custom alerts. For example, selecting the type **General Machines** and the class **Medium Machine Class II** will define alerts for the device as the example below:

Pre-defined alerts example

The user can use these options as templates and edit the alerts according to their needs. Alternatively, custom alerts can be set by clicking on **Add Alert**. The fields the user will have to fill in are as follows: * **Alert source**: the measurement to be monitored. This can be RMS velocity on any of the three axes, peak acceleration on any of the three axes, or temperature (minimum, maximum, or average). * **Alert label**: a name to differentiate the alert and help the user identify it across SolidRed. * **Severity**: available options are intermediate, warning, minor, major, or critical. * **Threshold value**: the value that needs to be met for the alert to trigger.

Custom alerts configuration

Clicking on the plus icon below the delete icon on the last defined alert level will let the user add another severity level for the alert. Up to 4 severity levels can be defined within a single alert. Finally, clicking the save button will apply the defined alerts to the device in question. Clicking on the eye icon next to the status of the ISO ISO-based alert will display a pop-up window with further insight into the alert. In this window, the user can look at the current status, recommended actions, related measurements and FFTs to analyze the status of the monitored machine. ### Device conditions These alerts are based on the trigger thresholds configured on the device. If the threshold is configured through SolidRed, this will be available on the summary table of the alert information. For the NEON Vibration Sensor, these alerts are thresholds on the measurements and spectrum alerts on the FFTs. ### Machine fault {% hint style="info" %} Only available for NEON Vibration Sensors using the communication protocol v4 onwards. {% endhint %} The machine fault alerts are based on the Machine Fault Indicator message of the NEON Vibration Sensor in the `common_fault` mode. In this section, common faults from the categories `one_x` , `two_x`, and `n_x` are shown, as well as their possible root causes and recommended actions. The harmonics are also displayed in the alert report. ### Bearing fault {% hint style="info" %} Only available for NEON Vibration Sensors using the communication protocol v4 onwards. {% endhint %} The bearing fault alerts are based on the Machine Fault Indicator message of the NEON Vibration Sensor in the `bearing_fault` mode. Here, the magnitude, frequency, and order of the automatically detected bearing fault are displayed, as well as the harmonics sent with the bearing fault message. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.twtg.io/docs/solidred-4.1/application-dashboards/vibration/alerts.md?ask= ``` The question should be specific, self-contained, and written in natural language.
