The main advantage of the ECO mode is that it
reduces the consumption of electrical power by
not running in the online mode. When this mode
is selected, the system works as an offline UPS
system, powered by Bypass source if Bypass source
is inside user’s defined range. Outside this range, the
UPS system will switch to online mode with 10ms
interrupt.
Three possible cases:
1. If Normal AC source (Mains 1) and Bypass AC
Source (Mains 2) are available:
15
and
17
LED are ON.
The load is supplied with AC power but not protected
in ECO mode.
2. If Normal AC source (Mains 1) is available, but
Bypass AC source (Mains 2) is not available:
15
LED is ON.
The audio alarm sounds intermittently.
The load is automatically supplied in Normal mode
via the Normal AC input.
3. Both Normal and Bypass AC sources not available
or out of tolerance:
15
LED is ON.
16
LED is ON.
The audio alarm sounds intermittently.
The load is powered by the battery power from the
UPS.
The LCD display indicates the battery remaining
back-up time.
