ALARMS
ON-BATTERY
When the UPS is operating on the batteries, the ON BATT LED will illuminate
and the audible alarm will sound once every ten-seconds. The alarm will stop
once the UPS returns to the AC normal mode.
LOW BATTERY WARNING
When the batteries reach the pre-determined level the BATT LOW LED will
illuminate and the audible alarm will sound two beeps every five-seconds. This
condition will continue until AC returns or the UPS shuts down from battery
exhaustion.
SELF TEST
The self test feature is useful to verify the correct operation of the UPS and the
condition of the batteries. With the UPS in the AC normal mode, press the ON/
Test/Alarm Silencer Button for 1-beep (2-seconds) to perform a battery test.
The UPS will perform a ten-second self test. During the self test, the UPS will
switch to battery power and the ON BATT LED will illuminate and the audible
alarm will sound. If the UPS fails a self test, one of the LEDs will remain
illuminated indicating the type of problem.
UPS FAULT
When the UPS detects a hardware fault, the FAULT LED will illuminate and the
UPS will sound a constant alarm. The fault condition, in some instances, may
be reset by turning the UPS off and then on again.
LOAD SHEDDING FUNCTION
The output receptacles are electrically wired into two segments to support the
"Load Shedding Function". The user can control the two segments individually
or both at the same time. The Load Shedding Function is controllable by the
Power Monitoring Software or the SNMP card.
OFF Button
Press the OFF button for 1-beep (2-seconds) to turn the UPS off. NOTE: The
input circuit breaker MUST be turned to the off position for the 208V models.
OUTPUT VOLTAGE SETTINGS
The inverter output voltage setting may be changed by the user to set the
desired Inverter output voltage. The inverter output voltage setting can be either
120VAC (208VAC) default or 110VAC (240VAC). The inverter output voltage
can be changed by using the Output voltage setting software. The software
program is available for download on the web site.
OVERLOAD
When the amount of load attached to the UPS exceeds its power rating, the
OVERLOAD LED will illuminate and the UPS will sound a constant alarm. This
alarm will remain on until the excess load is removed or the UPS’s self protec-
tion circuit shuts the UPS down.
COMMUNICATIONS PORTS (RS232 and USB)
The RS232 communication port is a standard DB9 female with both RS232 and
simulated contact closure capability. The UPS will poll the port and activate
the port for RS232 or contact closure in accordance with the type of cable it
finds connected to the port. To change the port configuration requires the unit
be turned off and restarted with the desired cable connected. The pinout for the
port is depicted per the chart below:
Pin 1: Simulated contact closure Low Battery Warning, NO
Pin 2: /TXD
Pin 3: /RXD and receive UPS shutdown command (connect to pin9 for 4-sec-
onds. The shutdown command is only active in the battery mode)
Pin 4: Not Used
Pin 5: Ground
Pin 6: Not Used
Pin 7: Not Used
Pin 8: Simulated contact closure AC fail, NO
Pin 9: Atx Signal (high level: 12V ± 2V, low level: -15V ± -2V)
WEAK/BAD BATTERY
The UPS automatically tests the battery’s condition and will illuminate the
REPLACE BATT LED and sound the alarm. This alarm will be repeated until
the batteries pass a self test. If the battery is weak or bad, the REPLACE
BATT LED will illuminate and the alarm will beep three times every five-minutes
until the battery is replaced. It is recommended that the UPS be allowed to
charge overnight before performing a battery test to confirm a Weak/Bad Bat-
tery condition.
NOTE: If the UPS has a REPLACE BATT Alarm after reconnecting or replacing
the batteries, the user must initiate a self test to clear the REPLACE BATT
Alarm. To initiate a self test see section 4 "SELF TEST".
POWER MONITORING SOFTWARE
The UPS comes with a Power Monitoring Software CD. See the software CD
for the installation of the Power Monitoring Software.
USB PORT
The USB protocol is HID. The HID USB driver is standard in the Windows OS.
Simply plug the USB cable into the UPS and the computer then follow the
prompts on the screen.
OPTION SLOT
The option slot on the rear panel of the UPS is for option cards. Contact your
local dealer for the available option cards.
RJ11 REPO (Remote Emergency Power Off) PORT
In the AC or the Battery mode short pin4 to pin5 for approximately 0.5-seconds
to shutdown the UPS. The UPS must be turned off and then back on again to
restart the UPS.
