4. Commissioning and operation
4.5 Alarm description
Three basic alarm types can be configured: alarm limit, alarm limit with delay, pressure change.
These alarms can be set using the "myWIKA wireless device" app via Bluetooth
the WIKA cloud.
For a customer connection without a WIKA app or WIKA cloud, the "Special documentation for LPWAN
tion specifications, model PEW-1000" or "Special documentation for Bluetooth
PEW-1000" must be observed.
A combination of alarm functions is possible, e.g. alarm limit for rising and falling pressure to define an operating
window for the application.
