LCD DISPLAY SELECT SWITCH
Momentarily press the "SELECT" switch on the front panel to browse through different power readings on the LCD Display. The LCD Display will show which one of four operational modes your UPS is currently in: Normal, Economy,
"NORMAL"MODE OPERATION
"ECONOMY'MODE OPERATION "ON BYPASS" MODE OPERATION
OPERATION ON BYPASS-VOLTAGE OUT OF RANGE
While in Bypass Mode, the UPS monitors the input voltage, which on Bypass equals the output voltage. If the output voltagepasses out of 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 voltagewas too high or too low a t one time, but has returned to nominal.
Bypass Voltage Condition | LCD Display Message |
>15Oh Higher than Nominal | BYPASS AC TOO HI |
>20% Lower than Nominal | BYPASS AC TOO M |
Was Too High. Now Nominal | BYPASS AC WAS HI |
Was Too Low. Now Nominal | BYPASS AC WAS LO |
OPERATION ON OVERLOAD
When the UPS detects an output overload, it will commence a countdown (the length of time depending on the severity of the overload). If the UPS is still overloaded a t the end of the countdown, the UPS will automatically shut down and go into Bypass Mode.
Overload Condition | LCD Display Message | Countdown to Shutdown | |
102% | - 125% | Overload 102% | 1 minute |

| Load=XXXOhX.XXKW |
