Speed alarms help monitor the speed of the production line, making sure lines run at their full potential 100% of the time. Speed alarms can help identify the otherwise hidden speed loss by notifying managers or operators about an unintentional reduction in speed.

How it works

The rule for a speed alarm is based on a percentage of the validated speed of the line. That means we define the trigger point for the alarm based on a percentage of the validated speed. Additionally, we also define the evaluation window in which we calculate the average speed before we trigger the alarm (see visualization below)

How to set it up

1. Find the sensor you want to set up the alarm on.
2. Go to the “Alarms” tab
3. Add a new alarm
4. Select the alarm type “Speed alarm”
5. Fill out the threshold x and evaluation window y
6. Add a subscriber

<aside> 🔎 Example

Let's say we want to get a notification if the line runs below 50% of its validated speed for 5 minutes. We set x to 50 %, and y to 300 seconds (5 minutes). Let's assume the line has a validated speed of 60 pcs/min. The alarm will now look at a window of the last 5 minutes of data and check if the avg. speed within this window drops below 30 pcs/min (50% of val speed).

If the last 5 minutes of data is interrupted by downtime, or a change in the configured validated speed, the alarm will not be triggered.
