MONITORING FEATURES
The Inverter includes an RS232 communication option
called UPSCOM. This is an RS232 connection to a
PC that can monitor in real time the three phase
information related to the UPS output and any abnormal
conditions that have occurred. Standard commercially
available software is provided. The RS232 Feature
is included at no additional charge.
Front Panel LCD
display and LED indicators.
This will report all
Inverter parameters. These includes input and output
voltages, currents, frequency, DC voltage and current,
as well as many other functions.
LCD Display.
Real time status, data
or historical events are displayed and the LCD display.
The Inverter parameters, real time clock, inverter,
buzzer also can be set through this LCD, The LCD
is back lighted by LEDs.
Status LEDs.
A series of LEDs representing
all the important information of the Inverter provide
information to the user. These LEDs are especially
important when abnormal conditions occur. LED descriptions
are as follows:
INVERTER ON
- Inverter is running normally.
INVERTER SS - Inverter
static switch is on while the reserve static switch
is opened (off).
SHORT CIRCUIT
– Inverter output is in short circuit state.
FUSE / OVERTEMP
SD – Inverter has shutdown due to
either fuse open or the temperature is too high.
INVERTER FAIL
SHUTDOWN – Inverter has shutdown
due to inverter AC output voltage too low.
BYPASS ON SHUTDOWN
– Inverter shutdown due bypass breaker is
closed when the inverter is running.
HIGH DC SHUTDOWN
– Inverter shutdown due to DC bus too high
when the inverter is running.
OVERLOAD SHUTDOWN
– Inverter shutdown due to overload of the
inverter for a period greater than the inverter
can accept. The inverter will start after 7 seconds.
70% LOAD
– load connected to the output is over 70%
of the UPS rating.
110% LOAD
– load connected to the output is over 110%
oh the UPS rating.
125% LOAD
- load connected to the output is over 125% of the
UPS rating.
150% LOAD
– load connected to the output is over 150%
of the UPS rating.
RESERVE AC FAIL
– reserve AC magnitude is out of range.
RESERVE FREQ
FAIL – reserve frequency is out of
range.
BATTERY LOW –
DC bus (or battery) is lower than 108VDC, low
battery shutdown will occur soon.
OTHER OPTIONS
DC INPUT BREAKER
OPTION
The optional DC Inout breaker disconnect is offered
to provide protection for the input.
SHOCK MOUNT OPTION
The cabinet can be shock mounted, using optional
rubber on coil type isolators. This will be enable
the unit to withstand shock levels as specified
in MIL-STD-901
RUGGEDIZING OPTION
This option will add conformal coating and other
additional internal structural members to allow
the unit to meet many portions of MIL-STD-810.
TURN ON SERVICE
OPTION
We offer a turn on service that will ensure the
Inverter has been properly installed and the full
warranty is in effect (failures caused by incorrect
installation are not covered by the warranty.) If
this option is selected, the customer will also
automatically receive an additional 3 months added
to the warranty at no additional charge.
SPARE PARTS
KIT OPTION
We offer a spare parts package that includes one
of each board, spare fuses, spare semiconductors,
and spare fans. These spare part kits are priced
lower when ordered with the initial order then if
they are ordered later on.

BATTERY
LOW SHUTDOWN – inverter shutdown
due to DC bus (or battery) is lower than approximately
100VDC (lower than the acceptable DC voltage of
the inverter).
HIGH DC – DC voltage over
150 VDC
EMERGENCY STOP – Inverter
shutdown due to emergency stop switch pushed.
DATA LINE – Blink when data
is transmitted to or received from the communication
port.
Warning LEDs.
When abnormal condition occurs, these LEDs will
light to warn the user of the cause of the fault
condition. Therefore all these LEDs are off under
normal condition. These LEDs are:
RESERVE FAIL – Reserve AC
input is abnormal either due to AC magnitude out
of range or frequency out of range.
FUSE/TEMP - Either inverter fuse
is open or over temperature has occurred.
OVERLOAD – Output is overloaded
by over 110%, 125% or 150%
HIGH DC – This LED will
light as long as the DC voltage is over 140VDC.
BAT LOW – This LED will
light when the DC voltage is lower than 108VDC.
BAT LOW STOP – This LED
will light when the DC voltage is lower than 100VDC,
inverter on is inhibited.
FAULT – The inverter is
off due to abnormal conditions such as overload,
short circuit, high DC, fuse over temperature, bypass
breaker on emergency stop.
Since these LEDs are located behind the transparent
window, the user can use them clearly without opening
the door.
AUDIBLE ALARM – The audible
alarm will beep under either one of the following
conditions:
INVERTER IS OVERLOADED-
> 110% beep once every 3 seconds
> 125% beep once every second
> 150% beep twice every second
INVERTER IS SHORT CIRCUITED –
Beeps continuously
FUSE OPEN– Beeps continuously
HEAT SINK OVER TEMPERATURE – Beeps
continuously
HIGH DC SHUTDOWN – Beeps continuously
BYPASS ON STOP - Beeps continuously
EMERGENCY ON STOP - Beeps continuously
The buzzer will also beep once every time the inverter
is switched on or off to acknowledge to the user
that his key entry is valid and accepted.
COMMUNICATIONS OPTIONS
We offer options for communications with this UPS
series. Some popular options available at additional
cost include the following:
UPSCAN: This is a hand held remote
display and control module with LCD and LED display
that can monitor via RS-485 UP to 99 UPS Units at
a remote distance of up to 3,000 feet.
UPSCALL: This is a modem that
will automatically dial out to a specified number
when an abnormal situation occurs.
NETAGENT: This provides capability
to monitor the UPS over the internet. It includes
the appropriate additional SNMP card and microprocessor.
The software required is provided by MEGATEC at
additional cost.
