Learn how to set up Vutlan logic schemes: Logic schemes & Logic schemes panel
Example
For example, you have a telecommunication rack with servers and equipment. You need to activate fans inside a rack when the temperature reaches 36°C. If the temperature reaches 44°C you need to activate fans, alarm the siren for 90 seconds, and notify the administrator via e-mail and SMS.
You have:
# | Device | Description |
|---|---|---|
1 | Temperature | Temperature sensor installed inside a rack |
2 | Power-1 Fun | Controls fans |
3 | Power-2 Alarm | Controls siren alarm |
4 | Mail admin | Notification via e-mail. Created by user |
5 | SMS admin | Notification via SMS. Created by user |
1. Edit the thresholds of "High warning" and "High alarm" levels for the temperature sensor. Set "High warning level" to 36°C and "High alarm level" to 44°C, with useless "Low" thresholds set to minimum.
2. Configure relay settings. Choose a name and set "Pulse duration", it determines the time at which the alarm will be activated.
3. Create "E-mail" and "SMS" notifications. Follow the steps in the section: Creating notifications.
4. Go to the "Logic Schemes" menu. Add 3 logic schemes as follows:
a. First logic scheme will turn on "Power-1 Fun" when the temperature reaches 36°C (high warning level).
b. Second logic scheme will turn on the "Power-1 Fan" when the temperature reaches 44°C (high alarm level). The "Power-2 Alarm" is switched to pulse for 90 seconds, as it was previously configured. SMS and e-mail notifications will be sent.
c. Third logic will turn off the "Power-1 Fan" and "Power-1 Alarm" when the temperature falls into "normal" ("Normal" level is between "low warning" and "high warning" levels. Thus below 36°C in this example).
