What does the LCD initial screen
mean? |
 |
You can generally view the measured values and all the alarms
on this screen, and can view and change data using menu by and the FUNCTION key.
If you do not press any key for 10 minutes, the screen goes off automatically.
By pressing any key, the LCD lights up again. |
|
 |
|
What is the command F0 used for? |
|
After pressing F0, you must put in a password. If you
put in the password '000000', you can change any individual setting,
all from one screen. |
|
|
|
What is Current State F1? |
|
By pressing F1, you can view the current rectifier settings as well as
alarm history data |
|
|
|
What is the EDIT F2? |
|
With EDIT F2, you can configure the system, set the upper/lower
values, configure the system operations, set the output voltage, etc.
|
|
|
|
What is Time Change F3? |
|
With F3, you can change the current time. |
|
|
|
What is Sound (On) F4? |
|
With F4, you can activate and deactivate audible alarm (sound). |
|
|
|
What is System State F5? |
|
With F5, you can view data and alarms stated
in real time for AC distributor, DC controller, rectifier units, and
the battery. |
|
|
|
What should I do when load sharing is not activated
between rectifier modules? |
|
There are three internal variable resistors on the front
plate of the rectifier module. Compare the load sharing state and
balance the load, turning the middle variable resistor clockwise using
a crosshead screwdriver. If the load is not shared even though you
try to adjust it, establish the output voltage again on the control
unit or check the load sharing state again by turning the rectifier
off and on. If the rectifier module does not work even after turning
it off and on, you have to replace the rectifier module. |
|
|
|
What should I do when the measured voltage
is different between rectifier modules? |
|
This situation means that the sensing reference of measuring
voltage is low. You can complement the value by adjusting the first
variable resistor using a cross-head screwdriver. |
|
|
|
What should I do when the AD alarm occurs? |
|
This alarm sounds when the upper/lower limit values
are wrongly specified for input/output voltage and current; when the
setting value is correct, but the actually measured value is different
from the measurement data; when the extension rack is used, and a
communication error occurs between the main rack and extension rack.
For the AD alarm, consult with the customer service representative.
|
|
|
|
What range is the input voltage?
|
|
It is 418~342V for 380V and 242~198V for 220V. |
|
|
|
What is the variable range of
the output voltage? |
|
The output voltage can be specified in the range of 56~48V, and
the current limit can be specified with 90~110%. |
|
|
|
What should I do when the DC alarm occurs? |
|
If a fuse for load and battery has blown, check the
fuse number whose error has occurred on the DC controller screen and
remove the cause of error. If no fuse has blown but the alarm sounds,
you have to replace the DSRC-ADI board. |
|
|
|
What are the RF alarms? |
|
AF, TH, OV, UV, MD, and CL problems of the rectifier unit
activate the alarm. |
|
|
|
What should I do in Fail
in the AF (ac fail)? |
|
This occurs when the AC input is abnormal in the unit.
If the main input is normal but a specific unit generates this alarm,
switch off the unit and replace it.
|
|
|
|
What should I do in Fail
in the TH (thermal)? |
|
This over-temperature alarm occurs when the internal
temperature is higher than 130 degrees. You have to cool or replace the unit. |
|
|
|
What should I do in Fail
in the OV (over volt)? |
|
This output high voltage alarm occurs when the output
voltage of the rectifier unit is greater than the upper limit value.
Press the reset switch of the unit or turn the input switch OFF/ON.
If the alarm does not disappear even after these measures, you have
to replace the unit. |
|
|
|
What should I do in Fail
in the UV (under voltage)? |
|
This output low voltage alarm occurs when the output
voltage of the rectifier unit is lower than the lower limit value
and when the output interval is instantaneously short. Press the reset
switch of the unit. If the alarm does not stop even after these measures,
you have to replace the unit. |
|
|
|
What does Fail in the MD (hold
mode) indicate? |
|
The operator has made the state
Standby, it is regarded as normal. |
|
|
|
What does Fail in the CF (communication
fail) indicate? |
|
There is a communication error between the rectifier unit
and the control panel. Consult with the customer service representative. |
|
|
|
What does Fail in the NC (no connection)
indicate? |
|
It occurs when the unit input switch gets disconnected during
normal operation or when the operator was forced to disconnect the switch. |
|
|
|
What does Fail in the CL (current
limit) indicate? |
|
It occurs when the current of unit is greater than 100%. |
|
|
|
When does the MJ (major) alarm
occur? |
|
It occurs when the fuse for output voltage, output current,
battery or load has blown out. |
|
|
|
When does the MN (minor) alarm
occur? |
|
It occurs if there is an error in input voltage, input current,
rectifier unit.
|
|
|
|
What methods are used to generate
alarms? |
|
Voltage method and contact point methods are alternatively
used: the voltage method has 0V for normal working and DC 52V for
an error, and the contact point method has low impedance (L) for normal
working and high impedance (H) for an error.
