MONITORING
FEATURES
The UPS 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 required. The
RS232 Feature is included at no additional charge.
Front Panel LCD display and LED indicators.
This will report all UPS parameters. These included
input and output voltages, currents, frequency,
battery voltage and battery current, as well as
many other functions.
LCD Display.
Real time status, data or historical events are
displayed and the LCD display. The UPS parameters,
real time clock, inverter, buzzer also can be
set through this LCD, The LCD is back lighted
by LEDs.
Status LEDs.
24 LEDs representing all the important information
of the UPS 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
– UPS 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 320VDC, low battery shutdown
will occur soon.
OTHER OPTIONS
BATTERY DISCONNECT
OPTION
The optional battery disconnect is offered to
provide protection for the batteries. The electrical
code requires a disconnect near the batteries.
We will mount this inside the battery enclosure
if ordered.
SHOCK MOUNT
OPTION
The UPS and battery cabinets can be shock mounted,
using optional rubber on coil type isolators.
This will be enable the unit to receipt shock
levels as specified in MIL-5-901.
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 UPS 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 295VDC (lower than the acceptable DC
voltage of the inverter).
RECT AC FAIL – Rectifier
AC magnitude is out of range.
ROTATION ERROR – Rectifier
AC phase rotation is incorrect
RECTIFIER SHUTDOWN – Rectifier
shutdown due to DC bus too high (over 445VDC),
will automatically restart 30 seconds after abnormal
situation has been cleared.
HIGH DC – DC voltage over
430 VDC and the bus voltage will be limited to
this voltage
BOOST CHARGE – The battery
is being boost charged by the rectifier.
BATTERY TEST – Battery is being
tested (automatic feature of the UPS)
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:
RECT AC FAIL – Rectifier AC input
is abnormal either due to AC magnitude out of
the range or phase rotation error; rectifier shutdown.
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 430VDC.
BAT LOW – This LED will light when
the DC voltage is lower than 320VDC.
BAT LOW STOP – This LED
will light when the DC voltage is lower than 295VDC,
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 se 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
BACK-UP
> 320 VDC, beep once every three seconds
< 320 VDC, beep twice every second
< 295 VDC, no beeping (silence due the battery
shutdown)
INVERTER IS SHORT CIRCUITED – Beeps
continuously
FUSE BROKEN – 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.
DCMON: This is a battery monitor
module that will monitor all the batteries in
each 29 battery string. This feature can provide
information on a defective battery before problems
cascade to other batteries in the total battery
bank.
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.
