Determining the exhaust times of the pressure switches
In order to query the exhausted status at the correct time, determine the exhaust times of the pressure
switches.
The exhaust times depend on the following factors:
–
Application, including drives and consumers
–
Configuration of the valve terminal
If the application or the configuration of the valve terminal is changed, recalculate the exhaust times.
