UPS Operating Modes
The UPS automatically calls up the modes in the table below. The LCD automatically updates
when the mode changes (Section 3.5, “The LCD and the Menu Tree,” Figure 3.5.1).
The modes below and on the next page are called up by you to adjust the unit to local conditions
(Section 3.6, “Controlling the UPS”):
Sense Type
This broadens the input parameters to accommodate the frequency and voltage fluctuations created by a
backup generator or a noisy line. If the unit constantly switches between Line and Battery modes due to a
noisy line, switching the parameters to Generator stops this.
The factory default setting is Normal, where the unit runs on Normal parameters. Switching to Generator
makes it run on Generator parameters.
