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. |
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.
