6. ERROR MESSAGE OF THE TEST
6.1 During the test, if the UPS emits a quick beep, it means the battery level is low. Please leave the UPS in normal
mode for at least 10 hours, and the batteries will be fully charged.
6.2 If the UPS emits a continuous beep during the test, it may be in an overload situation. The over load may result in
an unexpectedly short runtime during a blackout. Please turn off the computer and check if any equipment can be
removed from the UPS.
6.3 If the UPS emits a continuous urgent beep for 12 seconds after test, it means that the batteries are no good and
may need replacement.
6.4 The frequency auto-select function allows the UPS to detect the city power frequency and apply the appropriate
one (50 ~ 60Hz).However, if the frequency of city power is abnormal (outside the range 47 - 68Hz) the UPS will switch
to backup mode for protecting your computer (even the city power voltage is O.K.).
6.5 LED/Alarm Indication:
Visual, audible indicator
Green LED, no alarm
Red LED flashing, slow beeping, 2 beeps / 4 sec.
Red LED flashing, quick beeping, 4 beeps / sec
Red LED flashing, urgent beeping, 8 beeps / sec
Red LED flashing, long beep
Red LED flashing, one beep / 4 sec.
If any abnormal condition occurs, and the item 5.3 can not be executed, you will need to reset your UPS. Please push
the button for at least 10 sec. to shut down the UPS, and push the button again to re-start the UPS.
7. COMPUTER INTERFACE PORT
Pin2 : AC Power Failure
Pin4 : Common GND of Pin2 & Pin5
Pin5 : UPS Battery Low
Pin6 : Turn off UPS
Pin7 : GND of Pin6
The computer interface port is diagramed above for
your reference. Use Pin4 as the common of Pin2
and Pin5, Pin2 and Pin4 will become close loop from
open when the utility is fail, Pin5 and Pin4 will
become close loop from open when the battery level
is low.
The UPS will shut down when the high level from RS-232, sustained for 3 seconds, is applied between Pin6 and Pin7.
