Product Related Safety Precautions
The following are general safety precautions that are not related to any
specific procedures and therefore do not appear elsewhere in this
publication. They are recommended precautions that personnel must
understand and apply during many phases of installations, operations
and maintenance.
10 __________________________________________________________________ M210485EN-B
Chapter 1 ________________________________________________________ General Information
WARNING
For safety reasons, do not install the mast alone.
WARNING
For safety reasons, do not install the mast when wind speed is over
7 m/s.
WARNING
Always wear a safety helmet during mast installation.
WARNING
Be careful when erecting or tilting the mast. See that there are no
power lines or other obstacles above or behind the mast.
WARNING
Secure the mast properly with guy wires to prevent it from falling.
Tighten all the adjustment screws properly.
WARNING
Be sure that there are no persons under the mast during erecting or
tilting the mast.
WARNING
When erecting the mast with the winch, do not touch the wire with
your bare hands. Do not try to guide the wire.
WARNING
To minimize shock hazard, the instrument chassis and cabinet must
be connected to an electrical ground. The power cable must either be
plugged into an approved electrical outlet or the instrument must be
carefully grounded to a low-resistance safety ground.
VAISALA _______________________________________________________________________ 11
Installation Manual _________________________________________________________________
WARNING
Do not operate in an explosive atmosphere. Do not operate the
equipment in the presence of flammable gases or fumes. Operation of
any electrical instrument in such an environment constitutes a
definite safety hazard.
WARNING
Do not attempt internal service or adjustment unless another person,
capable of rendering first aid and resuscitation, is present.
WARNING
Do not service alone. Under no circumstances should any person
reach into parts and assemblies that are AC powered.
WARNING
Operating personnel must not remove instrument covers. Component
replacement or internal adjustments must be made by qualified
maintenance personnel. Do not replace components with the power
cable connected. Under certain conditions, dangerous voltages may
exist for some time even with the power cable disconnected. To
avoid injuries, disconnect power and discharge circuits before
touching them.
WARNING
Do not service the live system outdoors. Do not open units outdoors
when the enclosure contains line voltage levels.
CAUTION
Do not install substitute parts or modify the unit. Improper
modification can damage the product or lead to malfunction. Contact
Vaisala for repairs to ensure that safety features are maintained.
CAUTION
Be careful not to damage the sensors when tilting the mast.

Chapter 1 ________________________________________________________ General Information
NOTE
Send old batteries to secondary lead smelter for recycling. Place
neutralized slurry into sealed containers and handle as applicable with
state and federal regulations. Large water-diluted spills, after
neutralization and testing, should be managed in accordance with
approved local, state, and federal requirements. Consult the state
environmental agency and/or federal EPA (Environmental Protection
Agency).
ESD Protection
Electrostatic Discharge (ESD) can cause immediate or latent damage
to electronic circuits. Vaisala products are adequately protected
against ESD for their intended use. However, it is possible to damage
the product by delivering electrostatic discharges when touching,
removing, or inserting any objects inside the equipment housing.
To make sure you are not delivering high static voltages yourself:
- Handle ESD sensitive components on a properly grounded and
protected ESD workbench. When this is not possible, ground
yourself with a wrist strap and a resistive connection cord to the
equipment chassis before touching the boards. When neither of the
above is possible, touch a conductive part of the equipment chassis
with your other hand before touching the boards.
- Always hold the boards by the edges and avoid touching the
component contacts.
Trademarks
Microsoft, Windows, Windows NT, and Windows 2000 are

Ceilometer CT25KAM
VAISALA _______________________________________________________________________ 25
Installation Manual _________________________________________________________________
CT25KAM employs pulsed diode laser LIDAR (Light Detection and
Ranging) technology for cloud detection, precipitation, and other
obstructions to vision, and accurate cloud heights and vertical
visibility determination.
The standard measurement range of CT25KAM extends up to 25 000
feet (7.5 km) covering most heights where dense clouds appear. The
instrument is capable of reporting up to three cloud layers
simultaneously. It detects the cloud base reliably in fog, rain, snow,
and haze. If the cloud base is obscured, CT25KAM measures and
reports vertical visibility.
Extensive internal monitoring is supported by a comprehensive set of
user commands that can be given locally or remotely. Internal
monitoring includes a sensor measuring the outgoing laser pulse
energy, circuitry checking the receiver sensitivity, a sensor monitoring
window contamination, and two sensors measuring the tilt angle.
These and other internal measurements are used by the diagnostics
software and the detection algorithm for maximum reliability and ease
of use.
A special additional tilt sensor is provided as standard for
automatically compensating uneven terrain. Installation is made easy
and fast when no exact leveling is required. The cloud coverage
algorithm in the CT25KAM is a further development of the algorithm
specified by FAA. Cloud coverage (amount) is reported in 0 to 8
octas, according to WMO regulations.

weather sensor. In addition, PWD11A can measure the intensity and
amount of both liquid and solid precipitation.
The versatility of PWD11A is achieved with a unique operating
principle. PWD11A measures an estimate of the precipitation water
content with a capacitive device and combines this information with
optical scatter and temperature measurements. These three
independent measurements together sufficiently provide data for an
accurate evaluation of the prevailing visibility and weather type.
PWD11A is calibrated with reference to a highly accurate
transmissometer. An extensive self-diagnostic procedure continuously
monitors the sensor status. Dirt and foreign particles on the lens are
detected automatically, minimizing the risk of false high values. A
special calibration kit is provided as an option for conducting field
calibration under practically all weather conditions.
PWD11A is small and lightweight, thus being easy to install on the
sensor cross arm. In addition to the standard sensor operation, the
MAWS software adds extra features such as reporting of coded
weather type identifications as plain text in the output reports.

Chapter 3 ______________________________________________________ Installation of the Mast
CHAPTER 3
INSTALLATION OF THE MAST
This chapter provides instructions for preparing the installation and
selecting the site for the station. It also contains detailed information
on installing the tiltable pole mast.
Siting Criteria
Finding a suitable site for the MAWS201MP weather station is
important for getting representative ambient measurements. When
locating the weather station, consider the items presented in the
following sections. The descriptions are not comprehensive, for
further information refer to local and WMO recommendations.
Also note the tilting direction of the mast. When installed in the
northern hemisphere, the mast tilts to west. There should be a clear
area up to 9 m on the west side of the mast. The area should be free of
obstacles preventing the mast from being erected and tilted.
Soil Evaluation
Always, evaluate the soil to determine the appropriate type of the
foundation required. When designing the foundation, the local
construction companies must be consulted to find out about the soil
and frost conditions in your area. When the soil is frost-susceptible,
make sure to always use the proper insulation.
CAUTION
For mast base installation, the soil bearing capacity has to exceed
45 kPa (940 pounds-force/sq. foot).
VAISALA _______________________________________________________________________ 41
Installation Manual _________________________________________________________________
Wind Measurement
Allow sufficient clearance for the wind sensors, that is, the station
should not be located next to a building or any other object that might
affect the airflow. Refer to Figure 29 below and Figure 30 on page 43
that provide general guidelines for the mast location.
0306-027
Figure 29
Recommended Mast Location in Open Area
In general, there should be at least 150 m (≈ 500 ft.) open area to all
directions from the mast. The minimum distance between the mast
and obstacles is ten times the height of an obstacle. Refer to Figure 29
above.
The recommended minimum length (h in Figure 30 on page 43) for
the mast that is installed on top of a building is 1.5 times the height of
the building (H). When the diagonal (W) is less than the height (H),
the minimum length of the mast is 1.5 times W.

Chapter 3 ______________________________________________________ Installation of the Mast
0306-028
Figure 30
Recommended Mast Length on Top of a Building
Air Temperature and Relative
Humidity
NOTE
The radiation shield is important in protecting the sensor from direct
sunlight and should always be used.
For mast installations, the height of the sensor should be set between
1.5 to 2 meters. Avoid the following installation sites to ensure correct
measurements: shaded areas, steep slopes, heat sources, swamps, high
vegetation, and places that might hold water after rains.
Precipitation
QMR101M Rain Gauge is installed on the same sensor arm with the
air temperature and relative humidity probe. In general, objects should
not be closer to the gauge than a distance twice their height above the
gauge opening.
The orifice of the gauge must be on a horizontal plane, open to the
sky, and above the level of in-splashing and snow accumulation. In
general, objects should not be closer to the gauge than a distance twice
their height above the gauge orifice.
VAISALA _______________________________________________________________________ 43
Installation Manual _________________________________________________________________
In areas of homogeneous dense vegetation, the height of the
vegetation should be kept below the gauge orifice level by regular
mowing. Sites on a slope or on the roof of a building should be
avoided. Also hard flat surfaces such as concrete should be avoided to
prevent excessive in-splashing.
Lightning Detection
SA20M Lightning Detector is installed on the sensor arm of the mast.
The main siting consideration for the SA20M sensor is interference
from local obstructions. Any conducting object, except the pole mast,
that presents a profile of approximately 30 degrees, or more, above the
horizon of the antenna ground plane is an obstruction. For a metal
building (very wide, solid metallic wall) that is 9 m (30 feet) taller
than the mounted height of SA20M, the sensor should be placed at
least 18 m (60 feet) away. Refer to Figure 31 below.
9904-024
Figure 31
SA20M Vertical Obstruction (Side View)
Horizontal obstructions do not greatly effect the detection efficiency
of SA20M. However, it is desirable to have no obstructions to the
sensor. The horizontal angle obstructed by an object should not be
greater than 5 degrees; larger angles than this will affect accurate
reporting of strike bearing in the direction of the object as shown in
Figure 32 on page 45. The size of the obstruction dictates the degree
of the inaccuracy.
44 __________________________________________________________________ M210485EN-B
Chapter 3 ______________________________________________________ Installation of the Mast
9903-051
Figure 32
SA20M Horizontal Obstruction (Top View)
Siting of the SA20M sensor also depends on the location of buried
electrical cables and electrical transformers. Site the SA20M sensor
away from emitters of electromagnetic interference, such as buried
electrical cables, and electrical transformers. SA20M will send a
message to the handheld terminal if the siting has been unsuccessful.
NOTE
SA20M can not be installed inside a closed-in structure. It must
always be installed outdoors facing magnetic north.
Present Weather Detection
Present Weather Detector PWD11A is installed on the sensor arm of
the mast. Avoid setting the system up near high brush or grass,
because foreign objects in the sample volume may cause sudden
changes in the scatter signal.
For the location of PWD11A the main requirements are:
1.
PWD11A should be sited in such a way that the measurements
will be representative of the surrounding weather conditions.
PWD11A should ideally be located in such a way that the site
has a minimum clearance of 100 m from all large buildings and
other constructions that generate heat and/or obstruct
precipitation droplets. The shade of trees should also be avoided
as trees may cause changes in the microclimate.
VAISALA _______________________________________________________________________ 45
Installation Manual _________________________________________________________________
0008-003
Figure 33
Recommended Location of the PWD11A
2.
The site should be free of obstacles and reflective surfaces
disturbing the optical measurement as well as obvious sources of
contamination. It is recommended that there are no obstacles in
the line-of-sight of the transmitter and receiver units, see Figure
33 above. If the transmitter beam is reflected from obstacles
back to the receiver unit the sensor will indicate too low MOR
values, because the reflected signal can not be distinguished
from real scatter signal. Reflections can be detected by rotating
the sensor cross arm. Any reflections will change depending on
the cross arm orientation and the visibility reading will change
accordingly.
3.
The receiver and transmitter optics should not point towards
powerful light sources. It is recommended that the receiver will
point north in the northern hemisphere, and south in the southern
hemisphere. The receiver circuit may become saturated in bright
light, in which case the built-in diagnostics will indicate a
warning. Bright daylight will also increase the noise level in the
receiver.
4.
The transmitter and receiver should face away from any obvious
source of contamination such as spray from passing vehicles.
Dirty lenses will cause the sensor to report too high visibility
values. The sensor automatically detects excessive
contamination.
5.
Although PWD11A is designed to withstand harsh weather
conditions, there are locations where the environment places
further demands on installation. Arctic and comparable
environments may cause high snow and ice accumulation
requiring additional heating. In this case, consult Vaisala or its

Cloud Detection
Align the ceilometer with the optical window pointing away from the
sun, that is, north in the northern hemisphere (south in the southern
hemisphere), to keep excess sunlight from out of the sensor. When
siting the ceilometer make sure that the optical window can be
oriented so that it has clear view of the sky. The lens should not be
shadowed by any obstacles.
The ceilometer does not have to be mounted vertically straight,
because it is equipped with two tilt-angle sensors.
Site Preparation
Power Supply and Communication
Lines
Before assembling the mast the power supply and communication
lines must be available. The primary AC (mains) power service must
comply with the National Electrical Code (NEC) or equivalent
specifications for grounding the primary power service entrance. The
mains must be continuous and without spikes and blackouts. If the AC
(mains) voltage is fluctuating more than the given tolerance, AC
(mains) voltage stabilizers are recommended.
The following applies to all field cabling:
- Use armored field cables.
- Cables must be suitable for underground use.
- Check the cable core diameter according to maximum allowable
drop.
- Route the cables through conduits to the equipment.
- Check cable conduit diameters or use additional termination boxes.
- Ground the cable shield at both ends.
- Use spike and overvoltage protection devices at both ends of field
cables.
Always make a detailed cabling and wiring plan. Data transmission
lines from the outdoor sites to indoor devices have to be prepared
VAISALA _______________________________________________________________________ 47
Installation Manual _________________________________________________________________
carefully. Also the power supply for the equipment used needs to be
planned carefully.
It is recommended to use a conduit to protect the cables that connect
the indoor components to the outdoor components from damage and
moisture. Note also, that traffic, standing water, and the twist and
stress caused by the connectors can damage the cables.
Required Tools
For installing the mast, you need a set of Allen keys, two adjustable
wrenches, a water level, and a big hammer.
For details on the tools that are needed in the installation procedure of
the weather station components, refer to section Preparing Installation
on page 87.
Unpacking Instructions for the Mast
Inspection of the Delivery
Check the shipping boxes for possible damage. Check that there are
no loose parts or connectors before installing the mechanics of the

Foundation
Soil and Frost Conditions
When designing the foundation, a local construction company must be
consulted to find out about the soil and frost conditions in your area.
When the soil is frost-susceptible, make sure to always use the proper
insulation.
Orientation of the Mast
Refer to Figure 36 on page 52 and Figure 37 on page 53 for the
orientation of the mast. The concrete pads for guy wires have to be
placed so that the pole mast can be tilted west (east in the southern
hemisphere) by releasing only the guy wire 1.
To ease the orientation of the mast, the two-headed arrow is cut on the
orientation plate. "N" should face north and "S" should face south to
ensure the aiming of the weather station devices to the correct
position.

With mast installations equipment grounding and lightning protection
must be done separately. The main principles are described below:
- Proper equipment grounding is required for personnel safety and
for equipment protection. A piece of equipment is grounded by
connecting its metal structures and electrical equipment to an
external buried ground rod. Individual site requirements may
dictate changes in the procedures described in this manual.
Changes are permissible as long as equivalent protection to the
original requirements is provided for the system.
- The materials used in the manufacture of the grounding systems
must be chosen to prevent them from forming an electrolytic
couple. It is recommended to use copper (Cu).
WARNING
Failure to provide proper grounding may result in personnel injury or
death from electrical shock and may severely damage equipment.

Chapter 3 ______________________________________________________ Installation of the Mast
- The equipment grounding system and lightning protection
grounding system should be located as far as possible from each
other. Minimum recommended distance is 5 m (16 ft.). Due to this
the lightning rod grounding cable is routed down from the top of
the mast via the guy wire which is insulated from the mast
construction, refer to number 2 in Figure 66 on page 78. The
equipment grounding should be done near the concrete pad for the
mast as illustrated in Figure 66 on page 78.
- The recommended grounding resistance is 10 Ω or less for both the
grounding of lighting protection rod and for the equipment
grounding. Soil conditions (sand, rocks, etc.) and ground resistance
measurement determines the design and construction of the
grounding system. Buried ground rods and / or buried wire can be
used for the ground network. The type and combination used
depend on soil conditions (ease of installation) and on the value of
measured ground resistance (the most effective way of reducing
resistance to the required value of 10 Ω or less). Measurements of
the earth resistance shall be made at least 48 hours after rainfall.
- The connection between ground rods and equipment frames and
copper cables should be made with appropriate compression lugs,
bolts, nuts, and lock washers.
- Optionally, the top of the earth electrode can be housed inside
covered pit as illustrated in Figure 67 on page 80.
