Overload Messages

When the UPS detects an output overload, its LCD will switch to the following display:

OVERLOAD!

LOAD1 = XXX% X.XKW

OVERLOAD!

LOAD2 = XXX% X.XKW

The UPS will then begin a countdown. If the UPS is still overloaded at the end of the countdown, the UPS will automatically go to BYPASS MODE to protect its inverter. The duration of the countdown varies with the severity of the overload, as follows:

Overload Condition	Countdown Duration
102% - 125%	1 minute
125% - 150%	30 seconds
> 150%	Immediate Bypass

Bypass Messages

While in BYPASS MODE, the UPS monitors its input voltage and passes that input power along to connected equipment. The UPS will not provide battery backup in BYPASS MODE. If the output voltage deviates from an acceptable range (between 15% higher and 20% lower than nominal), the UPS displays the condition on its LCD and stops supplying output power to its load. If power levels return to an acceptable level, the UPS resumes supplying power to the load, and its LCD reports that output voltage was too high or too low at one time, but has returned to nominal.
