PRESENTATION OF SYSTEM
The LCD symbol
indicates that the bat-
tery is working (the AC source is not available),and it
will flicker every second when battery is low.
The battery symbol also could show battery level:
There are four segments to indicate the amount of
battery capacity remaining. The higher the battery
capacity, the more indicators that will be illuminated.
Each indicator designates a 25% capacity level.
Please see the following capacity level respectively.
This is:
–
100% to 76%
, all of the four indicators
illuminate.
–
75% to 51%
, three indicators illuminate.
–
50% to 26%
, two indicators illuminate.
–
25% to 11%
, only one indicator illumi-
nates.
–
10% to 0%
, none of the indicator illumi-
nates.
When the battery is empty, the symbol
will
flicker every second.
9. Output parameters (voltage & frequency):
This part
gives the information of the output, including output
voltage and output frequency.
Fig. 3.
The figure indicates that the output voltage is
230V and the output frequency is 50Hz.
10. Capacity of Load %
: The LCD gives the load informa-
tion by displaying the load percentage.
Fig. 4.
The figure indicates the capacity of Load.
Normally, the symbol
will not illuminate, but when
the load percentage is more than 110% (overload),it
will flicker every second. If over load is time out , it will
illuminate constantly.
11. Site Fault
: The Site Fault indicator
will
light when UPS is plugged into an improperly utility.
This function is only available for 120Vac models
12. Fault code
: When UPS fails, the corresponding LCD
symbol will illuminate to show the type of failure.
Battery bad
: When the battery of the UPS is bad,
the symbol
will be displayed constantly.
Over load time out
: When UPS is Over load time
out, the symbol
will be dis-
played constantly. At the same time, the symbol will
be displayed constantly, and the output voltage is
0Vac 0Hz.
Battery missing
: If the battery connection is not
good, the LCD will display “FAULT CODE 1”.
Fan fail
: If the fan is locked, The symbol “FAULT
CODE 2” will flicker every second; if the time is out.
The symbol will be displayed constantly.
Over temperature
: If the temperature of the UPS
is too high, The LCD will display “FAULT CODE 3”
constantly.
Output invalid
: If output voltage is out of range, the
LCD will display “FAULT CODE 4” constantly.
Battery overcharged
: The LCD will display “FAULT
CODE 5” constantly.
Output short circuit
: The LCD will display “FAULT
CODE 6” constantly.
Other fault type
: The LCD will display “FAULT
CODE 8” constantly.
13. Input type (Operation mode).
Fig. 5.
Operation mode indication
Normal
: The UPS accepts a input voltage range of
±20%.
Generator
: The low frequence transfer point
changes at 40Hz and there is not limit for the high
frequence transfer point.
Extended margin
: The UPS accepts a input
voltage margin of -30% to +20%.
14. Output voltage margin
: The UPS output voltage se-
lection: 110Vac / 120Vac / 127Vac o 220Vac / 230Vac
/ 240Vac.
Fig. 6.
Output voltage margin indication
110Vac/120Vac/127Vac are LV mode (low voltage).
220Vac/230Vac/240Vac are HV mode (high voltage).
Example: To a HV UPS, after selection the 230Vac
mode (default selection) by the switches “CNFG” and
“ENTER”, the output voltage will be approximately 230V,
and the LCD display will be how the next figure shows:

Indication after the selection of HV 230 Vac
mode.
