Swell Event
In case of configuring Swell event as “on”, the screen that configures Swell start voltage and Swell end voltage
are displayed. In case of configuring Swell event as “oFF”, the screen immediately moves to reference voltage
percentage setup screen.

Swell Start Voltage
Swell start voltage is configured as a percentage to reference voltage. Swell start event is generated when the
measured voltage goes above start voltage.
Setup range Description
102.0 - 999.0% [default 110.0%] Percentage of Swell reference voltage
