SAFETY INSTRUCTIONS
The operator and installer must read the appropriate safety instructions before attempting to install
or operate the equipment.
Indicates a hazardous situation which, if not avoided, will result in
death or serious injury.
Indicates a potentially hazardous situation which, if not avoided,
could result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided,
can result in minor or moderate injury.
Warning, Caution Prohibitive Action MandatoryAction
DANGER
Radio Frequency Radiation Hazard
The radar antenna emits the electromagnetic radio frequency (RF) energy which can be harmful,
particularly to your eyes. Do not look at theAntenna Unit from a close distance while the radar is in
operation, or expose yourself to the transmitting antenna at a close distance.
The distances at which RF radiation levels of 10 W/m 2exist are shown in the table below.
DO NOT approach closer than 9.1m (Safety standard is 10 W/m2) when radar is transmitting.
Note:
This value is applied when radar is installed in a public space. Value is defined as on human
body surface over a 6-minute period with the flux density averaged from the measurement.
Moreover, this measured value is measured by pointing the center of the antenna towards a
human. However this is the worst value, definition required by actual regulation is written here
as on safe side.
Distance from Antenna
9.1m
Power flux density
10 W/m2
WARNING
Do not open the radome.
Electrical shock can occur. Only qualified personnel should work inside the equipment.
Turn off the breaker in the SPU if opening the radome is required.
Wear a hard hat and safety belt when mounting the Antenna Unit.
Serious injury or death can result from falls or dropped items while installing or servicing the
radar components.
Do not use any other power except 100 to 240 VAC.
Connection of an incorrect power supply can cause fire or damage the equipment.
Turn off the power immediately if water leaks into the
equipment or smoke or fire is coming from the equipment.
Failure to turn off the equipment can cause fire or electrical shock.
Do not operate the equipment with wet hands.
Electrical shock can occur.
CAUTION
WARNING

RADIATION WARNING LABEL
Warning labels are attached to the equipment. Do not remove any label.
If a label is missing or damaged, contact us for the replacement.
WR2120 Restrictions
There are restrictions frequency band;
CH1: 9422.5MHz, CH2: 9427.5MHz, CH3: 9432.5MHz, CH4: 9437.5MHz in the following countries:
Switzerland, Lithuania, and Slovakia.
Do not disassemble or modify the equipment.
Fire or electrical shock can occur.
Use only the specified power cord.
Fire or damage to the equipment can result if a different cable is used.
Use the power supply grounded certainly.
Electrical shock or defect of operation can occur.
When a thunderbolt is expected, do not approach a system or
do not touch a hand.
There is a possibility of receiving an electric shock.
A worker's safety is guaranteed however the radar’s internal protection devices only
protect against indirect lightning and surges to the radar components. In case of a direct
lightning strike these protection devices may not protect radar or surrounding personnel.
Attach securely protective earth to the unit.
The protective earth (grounding) is required to the AC power supply to prevent electrical
shock.
CAUTION
Do not put liquid-filled containers on the top of the equipment.
Fire or electrical shock can occur if a liquid spills into the equipment.
Establish best possible surrounding space for apparatus.
This helps eliminate performance degradation and failure.
Do not impact the LCD glass.
Serious injury may occur due to broken glass.

SYSTEM CONFIGURATION
The observation system consists of an Antenna Unit (ATU), a Signal Processing Unit (SPU), and a Data
ProcessingUnit(DPU)
1) ATU(radome)
Radomeisto provide protectionforenclosedphysical environment. Inside the radome,thereisthe antenna
that rotates and radiates the radio waves. The radiated waves are backscattered by particles on the
propagationpath,return totheantenna,andareprocessedbyRFconverterto transferthesignalsto SPU
2) SPU
This unit is a relay point of LAN cable (1000Base-TX Cat5e or better, must use STP (Shielded Twisted
Pair)insteadof UTP(Unshielded TwistedPair)even to switcheson the poweroftheATU).
3) DPU(indoorunit)
DPU displaysradardataand operates theweatherradar.
Userneedstopreparetheexternalstoragedeviceforrecording theweatherobservationdataifnecessary.
DPUhas3portsforthededicatedLAN connections; ATU/SPU (LAN1),Internet(LAN2),andMONI-CON
(USB-LANadaptor).
Note: DonotinstallanysoftwareintoDPUoroperatethemonDPU,becauseitwill causeanoutofsystem
resourceproblem. Onlypre-installedapplicationcan be operated.
It is recommended to transport the observed data to the external storage, and then use WR_transfer
(pre-installed) to send data by FTPserver to share the observation data with the software whichis installed
in otherPC.

Volumescan briefoverview [3D data](Refer toFigure2.3)
This mode activates PPI scan to change the elevation angle up to 32 steps. It references the
VolumeScanPeriod andRainMaptimeindication.
Volume Scan is an observation of the azimuth rotation speed and multiple elevation angles as one
completepattern.
Observation starts at the specified minute (0 second) of every set interval. Whatever set operation
interval is used, all selected steps must be completed within the specified interval time. These
volume scan periods are also necessary to consider the elevation angle value, observation rotation
speed(rpm),movingspeedto elevationdirection(rpm),timetostabilizeafterelevationchange(fixed
at10deg.),andobservationinterval forsetting.

For example setting will fail with following settings. 6.0 rpm azimuth rotation speed for 6 rotations in
one minute would seem to be a correct setting when observing 6 elevation angles with 1 minute
intervals (setting theoperation interval to 1 (60 / [h]). However in Volume Scan, movement occurs in
the elevation direction and does not display while moving from one elevation to the next elevation
Because of the additional time required for these elevation movements the above observation
scenario of 6.0 [rpm] AZ rotation speed cannot be completed within the 1 (60 / [h]) volume scan
period.
Example of settings:
When observing these 6 elevation angles (3.5 /
5.5 / 9.0 / 12.0 / 16.2 / 22.0 [deg]) every one
minute, they can observed within a 58 second
periodbyusing settingsinTable 2.4.
(Rotationset to7.0 [rpm] in azimuthdirection)
Notes:
1> The ending time of scenario will be
different if elevation angle [deg] is
different even when using the same (0
to5)elevationnumbers.
2> Elevation movement azimuth rotation
speed [deg]isfixedat6.0deg.
3> When elevation movement mode is set to "AUTO" the upper limit value of elevation
movement speed can be set to 6.0 [rpm]. After the observation of one elevation angle the
movement to the next observed elevation can be completed faster. It is possible to select
"MANUAL",but "AUTO" settingisrecommended.
