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 avoid delivering high static voltages yourself: 1. 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, at least touch a conductive part of the equipment chassis with your other hand before touching the boards. 2. Always hold the boards by the edges and avoid touching the component s.

Principles of Measurements Wind Measurement Both wind speed and direction are measured using advanced ultrasonic technology. The sensor utilizes ultrasound to determine horizontal wind readings. The array of three equally-spaced ultrasonic transducers on a horizontal plane is an ideal design that ensures accurate wind measurement from all directions, without blind angles or corrupted readings. The wind sensor has no moving parts, which makes it virtually maintenance free. Wind speed and wind directions are determined by measuring the time it takes the ultrasound to travel from each transducer to the other two. The wind sensor measures the transit time (in both directions) along the three paths established by the array of transducers. This transit time depends on the wind speed along the ultrasonic path. For zero wind speed, both the forward and reverse transit times are the same. With wind along the sound path, the up-wind direction transit time increases and the down-wind transit time decreases. The wind speed is calculated from the measured transit times using the following formula: Vw = 0.5 x L x (1/ tf – 1/tr where: Vw = Wind speed L = Distance between the two transducers tf = Transit time in forward direction tr = Transit time in reverse direction Measuring the six transit times allows Vw to be computed for each of the three ultrasonic paths. The computed wind speeds are independent of altitude, temperature and humidity, which are cancelled out when the transit times are measured in both directions, although the individual transit times depend on these parameters. Using Vw values of two array paths is enough to compute wind speed and wind direction. A signal processing technique is used so that wind speed and wind direction are calculated from the two array paths of best quality. The wind speed is represented as a scalar speed in selected units (m/s, kt, mph, km/h). The wind direction is expressed in degrees (°). The wind Columbia Weather Systems, Inc.
14 Orion 420 Weather Station ________________________________________________________________________
direction reported indicates the direction that the wind comes from. North is represented as 0°, east as 90°, south as 180°, and west as 270°. The wind direction is not calculated when the wind speed drops below 0.05 m/s. In this case, the last calculated direction output remains until the wind speed increases again to the level of 0.05 m/s. The average values of wind speed and direction are calculated as a scalar average of all samples over the selected averaging time (1 ... 900 s). The sample count is based on a 4 Hz sampling rate. The minimum and maximum values of wind speed and direction represent the corresponding extremes during the averaging time.
Pressure, Temperature, and Relative Humidity (PTU) Module Barometric pressure, temperature, and humidity measurements are combined in an advanced sensor module (PTU) utilizing a capacitive measurement method for each parameter. The PTU module contains separate sensors for pressure, temperature, and humidity measurement. The measurement principle of the pressure, temperature, and humidity sensors is based on an advanced RC oscillator and two reference capacitors against which the capacitance of the sensors is continuously measured. The microprocessor of the transmitter performs compensation for the temperature dependency of the pressure and humidity sensors. Barometric pressure is measured using a capacitive silicon BAROCAP® sensor. The sensor has minimal hysteresis and excellent repeatability, as well as outstanding temperature and long-term stability. Temperature is measured with a capacitive ceramic THERMOCAP® sensor. Relative humidity measurement is based on a capacitive thin film polymer HUMICAP®180 sensor. The sensor is highly accurate with negligible hysteresis and excellent long-term stability in a wide range of environments. Radiation Shield: This module is mounted in a specially-designed radiation shield which protects the sensors from both scattered and direct sunlight and precipitation. The composite material in the plates offers excellent thermal characteristics and UV stabilized construction. The white outer surface reflects radiation, while the black inside absorbs accumulated heat. The internal sensor module is easily replaceable and readily available as a spare component. To order a replacement module, please use catalog no. 9581.

Orion 420 Weather Station 15 ________________________________________________________________________
Rainfall Measurement Rainfall is measured with an impact sensor, which detects the size and impact of individual rain drops. The signals resulting from the impacts are proportional to the volume of the drops. Hence, the signal from each drop can be converted directly to the accumulated rainfall. This measurement method eliminates flooding and clogging, as well as wetting and evaporation losses. The sensor transmitter uses RAINCAP® sensor 2 technology in precipitation measurement. The precipitation sensor is comprised of a steel cover and a piezoelectric sensor mounted on the bottom surface of the cover. The precipitation sensor detects the impact of individual raindrops. The signals from the impact are proportional to the volume of the drops. Advanced noise filtering technique is used to filter out signals originating from other sources than raindrops. The measured parameter is accumulated rainfall. Detection of each individual drop enables computing of rain amount with high resolution.

Orion 420 Weather Station 27 ________________________________________________________________________
Installing the Orion Sensor Transmitter Site Selection Finding a suitable site for the sensor transmitter is important for getting representative ambient measurements. The site should represent the general area of interest. The sensor transmitter should be installed in a location that is free from turbulence caused by nearby objects, such as trees or buildings. WARNING: To protect personnel (and the device), a lightning rod should be installed with the tip at least 40 inches (one meter) above the sensor transmitter. The rod must be properly grounded, compliant with all local applicable safety regulations.
Installing the Mounting Adapter
1. Insert the mounting adapter in the transmitter bottom side as shown in the diagram above. 2. Turn the adapter firmly until you feel that it has snapped into the locked position. 3. Align the transmitter in such a way that the arrow (at the bottom of the transmitter) points to north (see North Alignment). 4. Tighten the fixing screw to fix the adapter firmly to the mast. Columbia Weather Systems, Inc.
28 Orion 420 Weather Station ________________________________________________________________________
North Alignment To help with alignment, there is an arrow and text North on the bottom of the transmitter. The transmitter should be aligned in such a way that this arrow points to the north. Wind direction can be referenced to true north, which uses the earth’s geographic meridians, or magnetic north, which is read with a magnetic com. The magnetic declination is the difference in degrees between the true north and magnetic north. Com Alignment
1. If the sensor transmitter is already mounted, loosen the fixing screw on the mounting adapter. 2. Use a com to determine that the transducer heads are exactly in line with the com and that the arrow on the bottom of the transmitter points to north. 3. Tighten the fixing screw on the mounting adapter when done. Once the sensor transmitter is aligned to north, the transmitter can be removed from the mounting adapter without losing the north orientation.
Installing the Mast There are three acceptable methods for mounting the mast to a roof or building structure: Sloped roof mounting, flat roof mounting or wall mounting. See Optional Sensor Mounting Hardware for more information.
Columbia Weather Systems, Inc.
Orion 420 Weather Station 29 ________________________________________________________________________
Location Do not attach the sensor transmitter to a radio transmitting mast or tower. Select a mounting location that will allow the sensor cable to be routed away from other data cables to avoid interference. Never route sensor cables in tall trees. Do not mount sensors close to power lines or telephone lines. For normal roof mounting, the recommended minimum distance from power or telephone lines is 25 ft. (8 m). Use extreme caution when working close to power lines.
Mounting Method Choose the appropriate mounting method for the installation and obtain any necessary mounting hardware. Refer to Section 4 for information on optional sensor mounting hardware and accessories which are available from the factory. If the mounting hardware is not obtained from the factory, be certain to use metal parts which are plated or galvanized to assure maximum longevity. Secure the mast to the roof, using guy wires with sufficient tensile strength or to building wall using a wall-mount hardware kit.
Routing Cable Use plastic tie wraps to secure the cable to mast, particularly at the mast base. Tighten the tie wraps securely and clip off any excess length with a wire cutter tool. Route the cable back to the Interface Module
CAUTION: There may be electric wires in the wall. When routing cable through walls, we recommend that you shut off the electricity in the room(s) where you are drilling.
Any mast or tower should always be properly earth grounded to minimize electrical storm damage. The use of a properly grounded metal mast or tower, however, does not insure protection from electrostatic discharge. These items could become electrically charged resulting in damage to the sensors and/or console. This could damage the system in the event of an electrical storm. Use insulated standoffs when routing cable to help avoid this problem. Note: If the standard 50 ft. cable provided with the sensor transmitter is not long enough, it may be extended by splicing on an appropriate length Columbia Weather Systems, Inc.
30 Orion 420 Weather Station ________________________________________________________________________
of 22-gauge, stranded, seven conductor shielded cable with the same color code. When cutting and splicing, insure good s, proper color coding of the terminal leads, and a good seal. (A good solder splice, and water proof insulation are essential; merely twisting the respective wires together is not adequate.) Additional cable (Catalog No. 81545) and a water tight splice kit (Cat. No. 81580) are available from the factory. Once the sensor transmitter has been placed, route the cable back to the Orion 420 enclosure.
Connecting the Sensor Transmitter to the Orion 420 Enclosure Using a #1 Straight Slot screwdriver, attach the wires from the end of the sensor cable to the terminal block screws as shown below:
For heated sensor transmitters, connect the brown wire along with the red wire to position 1 and connect the blue wire along with the white and bare to terminal 2.

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 avoid delivering high static voltages yourself: 1. 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, at least touch a conductive part of the equipment chassis with your other hand before touching the boards. 2. Always hold the boards by the edges and avoid touching the component s.

Principles of Measurements Wind Measurement Both wind speed and direction are measured using advanced ultrasonic technology. The sensor utilizes ultrasound to determine horizontal wind readings. The array of three equally-spaced ultrasonic transducers on a horizontal plane is an ideal design that ensures accurate wind measurement from all directions, without blind angles or corrupted readings. The wind sensor has no moving parts, which makes it virtually maintenance free. Wind speed and wind directions are determined by measuring the time it takes the ultrasound to travel from each transducer to the other two. The wind sensor measures the transit time (in both directions) along the three paths established by the array of transducers. This transit time depends on the wind speed along the ultrasonic path. For zero wind speed, both the forward and reverse transit times are the same. With wind along the sound path, the up-wind direction transit time increases and the down-wind transit time decreases. The wind speed is calculated from the measured transit times using the following formula: Vw = 0.5 x L x (1/ tf – 1/tr where: Vw = Wind speed L = Distance between the two transducers tf = Transit time in forward direction tr = Transit time in reverse direction Measuring the six transit times allows Vw to be computed for each of the three ultrasonic paths. The computed wind speeds are independent of altitude, temperature and humidity, which are cancelled out when the transit times are measured in both directions, although the individual transit times depend on these parameters. Using Vw values of two array paths is enough to compute wind speed and wind direction. A signal processing technique is used so that wind speed and wind direction are calculated from the two array paths of best quality. The wind speed is represented as a scalar speed in selected units (m/s, kt, mph, km/h). The wind direction is expressed in degrees (°). The wind Columbia Weather Systems, Inc.
14 Orion 420 Weather Station ________________________________________________________________________
direction reported indicates the direction that the wind comes from. North is represented as 0°, east as 90°, south as 180°, and west as 270°. The wind direction is not calculated when the wind speed drops below 0.05 m/s. In this case, the last calculated direction output remains until the wind speed increases again to the level of 0.05 m/s. The average values of wind speed and direction are calculated as a scalar average of all samples over the selected averaging time (1 ... 900 s). The sample count is based on a 4 Hz sampling rate. The minimum and maximum values of wind speed and direction represent the corresponding extremes during the averaging time.
Pressure, Temperature, and Relative Humidity (PTU) Module Barometric pressure, temperature, and humidity measurements are combined in an advanced sensor module (PTU) utilizing a capacitive measurement method for each parameter. The PTU module contains separate sensors for pressure, temperature, and humidity measurement. The measurement principle of the pressure, temperature, and humidity sensors is based on an advanced RC oscillator and two reference capacitors against which the capacitance of the sensors is continuously measured. The microprocessor of the transmitter performs compensation for the temperature dependency of the pressure and humidity sensors. Barometric pressure is measured using a capacitive silicon BAROCAP® sensor. The sensor has minimal hysteresis and excellent repeatability, as well as outstanding temperature and long-term stability. Temperature is measured with a capacitive ceramic THERMOCAP® sensor. Relative humidity measurement is based on a capacitive thin film polymer HUMICAP®180 sensor. The sensor is highly accurate with negligible hysteresis and excellent long-term stability in a wide range of environments. Radiation Shield: This module is mounted in a specially-designed radiation shield which protects the sensors from both scattered and direct sunlight and precipitation. The composite material in the plates offers excellent thermal characteristics and UV stabilized construction. The white outer surface reflects radiation, while the black inside absorbs accumulated heat. The internal sensor module is easily replaceable and readily available as a spare component. To order a replacement module, please use catalog no. 9581.

Orion 420 Weather Station 15 ________________________________________________________________________
Rainfall Measurement Rainfall is measured with an impact sensor, which detects the size and impact of individual rain drops. The signals resulting from the impacts are proportional to the volume of the drops. Hence, the signal from each drop can be converted directly to the accumulated rainfall. This measurement method eliminates flooding and clogging, as well as wetting and evaporation losses. The sensor transmitter uses RAINCAP® sensor 2 technology in precipitation measurement. The precipitation sensor is comprised of a steel cover and a piezoelectric sensor mounted on the bottom surface of the cover. The precipitation sensor detects the impact of individual raindrops. The signals from the impact are proportional to the volume of the drops. Advanced noise filtering technique is used to filter out signals originating from other sources than raindrops. The measured parameter is accumulated rainfall. Detection of each individual drop enables computing of rain amount with high resolution.

Standard system includes: Orion Sensor Transmitter 50 ft sensor cable + additional cable length if ordered Orion 420 Weatherproof Enclosure Manual Inspect all system components for obvious shipping damage (Refer to “Important Notice: Shipping Damage” in case of damage). Save the shipping carton and packing material in case the unit needs to be returned to the factory. If the system does not operate or calibrate properly, see Section 6: Maintenance and Section 7: Troubleshooting, for further instructions.
Columbia Weather Systems, Inc.
Orion 420 Weather Station 27 ________________________________________________________________________
Installing the Orion Sensor Transmitter Site Selection Finding a suitable site for the sensor transmitter is important for getting representative ambient measurements. The site should represent the general area of interest. The sensor transmitter should be installed in a location that is free from turbulence caused by nearby objects, such as trees or buildings. WARNING: To protect personnel (and the device), a lightning rod should be installed with the tip at least 40 inches (one meter) above the sensor transmitter. The rod must be properly grounded, compliant with all local applicable safety regulations.
Installing the Mounting Adapter
1. Insert the mounting adapter in the transmitter bottom side as shown in the diagram above. 2. Turn the adapter firmly until you feel that it has snapped into the locked position. 3. Align the transmitter in such a way that the arrow (at the bottom of the transmitter) points to north (see North Alignment). 4. Tighten the fixing screw to fix the adapter firmly to the mast. Columbia Weather Systems, Inc.
28 Orion 420 Weather Station ________________________________________________________________________
North Alignment To help with alignment, there is an arrow and text North on the bottom of the transmitter. The transmitter should be aligned in such a way that this arrow points to the north. Wind direction can be referenced to true north, which uses the earth’s geographic meridians, or magnetic north, which is read with a magnetic com. The magnetic declination is the difference in degrees between the true north and magnetic north. Com Alignment
1. If the sensor transmitter is already mounted, loosen the fixing screw on the mounting adapter. 2. Use a com to determine that the transducer heads are exactly in line with the com and that the arrow on the bottom of the transmitter points to north. 3. Tighten the fixing screw on the mounting adapter when done. Once the sensor transmitter is aligned to north, the transmitter can be removed from the mounting adapter without losing the north orientation.
Installing the Mast There are three acceptable methods for mounting the mast to a roof or building structure: Sloped roof mounting, flat roof mounting or wall mounting. See Optional Sensor Mounting Hardware for more information.
Columbia Weather Systems, Inc.
Orion 420 Weather Station 29 ________________________________________________________________________
Location Do not attach the sensor transmitter to a radio transmitting mast or tower. Select a mounting location that will allow the sensor cable to be routed away from other data cables to avoid interference. Never route sensor cables in tall trees. Do not mount sensors close to power lines or telephone lines. For normal roof mounting, the recommended minimum distance from power or telephone lines is 25 ft. (8 m). Use extreme caution when working close to power lines.
Mounting Method Choose the appropriate mounting method for the installation and obtain any necessary mounting hardware. Refer to Section 4 for information on optional sensor mounting hardware and accessories which are available from the factory. If the mounting hardware is not obtained from the factory, be certain to use metal parts which are plated or galvanized to assure maximum longevity. Secure the mast to the roof, using guy wires with sufficient tensile strength or to building wall using a wall-mount hardware kit.
Routing Cable Use plastic tie wraps to secure the cable to mast, particularly at the mast base. Tighten the tie wraps securely and clip off any excess length with a wire cutter tool. Route the cable back to the Interface Module
CAUTION: There may be electric wires in the wall. When routing cable through walls, we recommend that you shut off the electricity in the room(s) where you are drilling.
Any mast or tower should always be properly earth grounded to minimize electrical storm damage. The use of a properly grounded metal mast or tower, however, does not insure protection from electrostatic discharge. These items could become electrically charged resulting in damage to the sensors and/or console. This could damage the system in the event of an electrical storm. Use insulated standoffs when routing cable to help avoid this problem. Note: If the standard 50 ft. cable provided with the sensor transmitter is not long enough, it may be extended by splicing on an appropriate length Columbia Weather Systems, Inc.
30 Orion 420 Weather Station ________________________________________________________________________
of 22-gauge, stranded, seven conductor shielded cable with the same color code. When cutting and splicing, insure good s, proper color coding of the terminal leads, and a good seal. (A good solder splice, and water proof insulation are essential; merely twisting the respective wires together is not adequate.) Additional cable (Catalog No. 81545) and a water tight splice kit (Cat. No. 81580) are available from the factory. Once the sensor transmitter has been placed, route the cable back to the Orion 420 enclosure.
Connecting the Sensor Transmitter to the Orion 420 Enclosure Using a #1 Straight Slot screwdriver, attach the wires from the end of the sensor cable to the terminal block screws as shown below:
For heated sensor transmitters, connect the brown wire along with the red wire to position 1 and connect the blue wire along with the white and bare to terminal 2.
