How To Set Alarms

Updated over 5 months ago

Setting alarms in Farsight® is a useful process. Alarms help you automatically keep track of specific events that are of particular importance to your operations, like faults, silent outages, warnings, misalignments, temperature checks and others.

Requirements

  • A Farsight® account

  • An onboarded asset that has been correctly setup and can now be monitored

Create Alarm Trigger - Preset

Go to: Alarms > Alarm Triggers > Create Alarm Trigger

  1. Navigate through the different tabs for Preset, Advanced and Expression alarm triggers

  2. Setup alarm notifications for In-App, Slack, Email and Teams, depending on subscription level

  3. Choose the desired alarm type from the dropdown

  4. Set the desired severity from 1 to 5, with 5 being the least severe

  5. The area is automatically set by your choice of preset alarm types. For Advanced and Expression alarms you will be required to select one of the pre-existing areas, or define a new area

  6. Select Alarm Trigger Targets from the dropdown. You can choose multiple assets for monitoring

  7. The Asset Group is disabled when a selection is made in the Assets Selector (first input). Since Alarm Triggers can be either manual or automatic selection of sites and assets, each field will be disabled if the other one is used

  8. Set your own custom alarm message

  9. Set your own custom detail code in the format: <description><code>

  10. Set your alarm trigger delay. If you click on More Options you can also set end delay

  11. Set the minimum time between triggers and between endings. Choices are for minutes, hours, days and weeks

  12. Toggle on to enable the alarm trigger

  13. Click on the Save Configuration button to save the alarm

Create Alarm Trigger – Advanced

Go to: Alarms > Alarm Triggers > Create Alarm Trigger > Advanced

  1. Name your new alarm

  2. Set up a custom alarm message

  3. Pick your area from the dropdown. The alarm area works as an added layer of categorization. Areas such as Environmental, Error and Stop are all a type of category.

  4. Set up a custom alarm code

  5. Select Alarm Trigger Targets from the assets in the dropdown

  6. Asset group is auto completed

  7. Select alarm type depending on chosen target

  8. Select the severity from 1 to 5 with 5 being the least severe

  9. Add extra alarm Criteria. You will have to name the Indicator, Operator and give details. See notes for examples

  10. Clear all filters and start over

  11. Set your trigger Delay

  12. Enable the alarm Trigger

  13. Save Configuration

Example Alarm Candidates

When adding a new criteria, you will be given the chance to set your own custom settings. See below 2 these examples:

Advanced

a). Alarm for Blade pitch angle misaligned

Condition:

  • Blade Position (°) > 20

    AND

  • Wind Speed (m/s) > 15

    Description: Should be triggered when the blade pitch angle is too high for the current wind conditions.

b). Alarm for Turbine Overheating

Condition:

  • Rotor 1 Temperature (°C) > 90

    OR

  • Rotor 2 Temperature (°C) > 90

    OR

  • Stator 1 Temperature (°C) > 90

    OR

  • Stator 2 Temperature (°C) > 90

    Description: Should be triggered when the temperature exceeds 90°C for any rotor or stator.

Create Alarm Trigger – Expression

Go to: Alarms > Alarm Triggers > Create Alarm Trigger > Expression

  1. Click on Glossary to see what available signals you can use

  2. Write the expression you want to use

Expression Glossary

You can check the expression glossary for examples you can use.


​

  1. Switch between tabs to see expressions available for various manufacturers

  2. Use the filter to search for an expression

Example Alarm Candidates

Expression-based

a). Alarm for Underperforming turbine v1

  • Expression: WTUR1.W < (WNAC1.WdSpd * 10) AND WNAC1.WdSpd > 5

    This should trigger if the turbine's active power is less than 10kW per m/s of the wind speed reported at the nacelle level.

b). Alarm for Underperforming turbine v2

  • Expression: WTUR1.W < (NomP * 0.70) AND WNAC1.WdSpd > 10 AND WNAC1.WdSpd < 25

    This alarm detects if a wind turbine is significantly underperforming (producing much less active power than its nominal capacity) even when the wind speed is high enough that it should be operating near its rated power. This often indicates a fault, curtailment, or major inefficiency.
