Important Notice: Shipping Damage

BEFORE YOU READ ANY FURTHER, please inspect all system components for obvious shipping damage.
The weather station is a high precision instrument and can be damaged by rough handling. Your unit was
packaged to minimize the possibility of damage in transit. Please save the shipping container for any future
shipment of your weather station.

In the event your order arrives in damaged condition, it is important that the following steps be taken immediately.
The title transfers automatically to you, the customer, once the material is entrusted to the transport company.

NOTE: DO NOT RETURN THE INSTRUMENT TO COLUMBIA WEATHER SYSTEMS until the following steps are
completed. Failure to follow this request will jeopardize your claim.

1. Open the container and inspect the contents. Do not throw away the container or any damaged parts. Try 
    to keep items in the same condition as originally received.

2. Notify the transport company immediately.

3. Request the transport company’s representative inspect the shipment personally.

4. After inspection, request a Return Materials Authorization (RMA) from Columbia Weather Systems by 
    calling (503) 629-0887.

5. Return approved items to us at the following address:

Columbia Weather Systems, Inc.
2240 NE Griffin Oaks Street, Suite 100
Hillsboro, OR 97124

6. After a repair evaluation, an estimate of the cost of repair will be sent to you.

 

ESD Protection

Electrostatic Discharge (ESD) can cause immediate or latent damage to electronic circuits. The Weather Station is
adequately protected against ESD for its 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 contacts.

The system enclosure includes the following:

  • AC power supply with 24VDC output
  • Weather MicroServer
  • RS-485 Terminal Strip
  • Two solar amplifiers

The system enclosure is weatherproof and includes hardware to mount the unit on a mast.

Weather MicroServer

The Weather MicroServer uses a small computer board that runs an embedded Linux operating system.
The MicroServer has 2GB flash memory for data logging and operation.
The MicroServer has two RS-232 COM ports and an Ethernet port.

Sunlight_2.png

The MicroServer offers the following:

  • XML Weather Data
  • FTP weather data in XML or CSV format
  • Modbus/TCP, Modbus RTU (Serial RS-232), and Modbus ASCI interfaces
  • SNMP interface
  • Weather Underground interface
  • CWOP interface
  • Three months of data logging at 1-minute interval
  • Interface to optional visibility and solar radiation sensors

MicroServer Configuration

The MicroServer is set to a default IP address of 192.168.0.50.
To connect to the MicroServer using a computer, set the computer to a static IP address of 192.168.0.49.

Use an Internet browser to connect to the MicroServer over its IP address.

Tripod and Tiedown Kit

Sunlight_4.png

The meteorological tripod is designed to provide up to 10 feet of stable, secure support for your meteorological sensors.

Constructed from welded aluminum and clear anodized for appearance and longevity, the 15-pound tripod can
easily support up to 60 pounds of equipment. An optional tie-down kit allows for additional security in high-wind areas.

To install, insert the legs into the main body and secure with stainless steel retainer pins. Extend the mast to the
desired height and insert another retainer pin. Install the guy wires to complete the set-up.

Tripod Parts List

Item # Description Qty

  1. Body/Mast Assembly 1
  2. Legs 3
  3. Retainer Pins 4
  4. Guy Wire Ring with 1
  5. Wires and Turnbuckles
  6. Anchor Screw with Chain Not included in this configuration
  7. Clamp with Strap 1
  8. Retainer Pin 1

Installing the Air (Ambient) Temperature Sensor

The air temperature sensor is installed in the self-aspirating radiation shield.

Sunlight_6.png

The temperature radiation shield should be mounted on the pole facing the north.

Installing the panel temperature sensor

The panel temperature sensor can be attached to the solar panel using a 5-minute epoxy.
Use tie wraps to secure the cable to the panel frame.

Installing the solar radiation sensor

 The solar radiation sensor can be installed on the mast using the hardware included to provide solar radiation
measurement.

Two types of brackets are provided: one for global radiation measurement, and the second for POA radiation
measurement.

Plane of Array Solar Radiation:

Install the solar sensor on the POA bracket using the provided screws, washers, and nuts. Use the two holes
marked in the photo below:

Sunlight_7.png

Install the bracket on the pole using the two sets of u-bots:

Sunlight_8.png   Sunlight_9.png

The POA solar sensor should be facing the south in order for the pole not to shadow the sensors.

Global Solar Radiation:

Remove the three top screws and discard.

Sunlight_10.png

Change the position of the U-bracket to allow for mounting on a vertical pole

Sunlight_11.png

Install the sensor on the bracket using the provided screws, washers, and nuts. Mount the bracket on the pole.

Sunlight_12.png

Make sure the sensor is level.  If not, loosen the mounting screws and adjust the leveling screws to achieve level installation.

Sunlight_13.png

Note:

Each Hukseflux LP02 solar radiation sensor comes with a unique sensitivity value. Therefore it is important that the
sensors are connected to the correct solar input (Solar 1 or Solar 2).

Sunlight_14.png

If the solar sensor is replaced in the future, then the sensitivity/factor needs to be entered in the MicroServer
interface.

Connecting sensors to the MicroServer

Sunlight_15.png

Connect the panel temperature sensor to Channel 2.

Connect the air temperature sensor to Channel 3.

Connecting to MicroServer to RS-485

Sunlight_16.png

The Modbus RTU is set to 9600 baud rate, none parity with a Modbus address of 51.

Modbus Registers

Weather MicroServer with Modbus TCP/IP Slave Interface or Modbus/RTU over COM2 (RS-485)

32-Bit Registers

All data accessed via (read only) input registers [Modbus function code 3]

Data type Long = Signed 32 bit value

Data type Float = 32 bit floating point value

sunlight_numbers.png


Notes:
For each of the available measurements, the two registers immediately following the value contain the posix time
value of the time that value was last updated. For example: Panel/Cell temperature value is stored in registers 253
and 254. The last update timestamp is stored in registers 255 and 256 and is a 32-bit integer value.

The posix time values are 32-bit integers; all the values are Modbus input registers.
