CPEC306 Closed-Path Eddy-Covariance System

Do not connect or disconnect the EC155 gas analyzer head or the CSAT3A son- ic anemometer head from the EC100 electronics while the EC100 is powered. Doing so can result in unpredictable performance of the system or damage to the instrument head.

Grounding electrical components in the measurement system is critical. Prop- er earth (chassis) grounding will ensure maximum electrostatic discharge (ESD) protection and higher measurement accuracy.

Use care when connecting and disconnecting tube fittings to avoid introduc- ing dust or other contaminants.

Do not overtighten the tube fittings. Consult the manual for information on proper connection.

The CPEC306 power source should be designed thoughtfully to ensure unin- terrupted power. If needed, contact Campbell Scientific for assistance.

Retain all spare caps and plugs as these are required when shipping or storing the CPEC306 system.

IMPORTANT NOTE: This Quick Deploy Guide is meant to be a general reference to give the installer an overview of the steps required to make this system operational. The Owners Manual is the definitive source for detailed installation instructions and information.

4. Connect the EC155 and CSAT3A to the electronics.

5. Ground the tripod and the enclosures.

6. Connect the system plumbing.

7. Wiring.

Connect the SDM from the main enclosure and EC100 power cables to the EC100 electronics.

Draw the EC100 power cable and EC100 SDM cable through the feedthrough at the bottom of the CPEC306 enclosure and connect them to the DINrail.

8. Datalogger

Insert a MicroSD card into the datalogger and connect power.

Turn on the +12 Vdc power supply and use either LoggerNet, PC200W, or PC400 on a laptop to configure settings and zero/span. If using the CR1000KD keypad, use the instruc- tions on the front page of this quick deploy guide.

1. Connect to the datalogger

2. Connect and select the Const_Table within the EasyFluxTM DL program.

3. Confirm all the sensors used at the site are set to -1. To change a value in this table, right-click on the current value and select View/Modify from the pop-up menu. Press Apply once the new value has been entered. Once all of the sensors and constant settings are correct, scroll to the bottom and set ApplyAndRestart to true.

4. Review the Public table and confirm that site specific variables are set appropriately. Note: Setting these variables does not require an ApplyAndRestart.

2. Setup and mount sensors

Mount the EC155 bypass tube.

Connect the CM250 mount to the crossarm and then connect the sensors mounted on the Mounting Platform, as shown. Use the bubble level on the CSAT3A to level the platform.

3. Mount the enclosures. Mount the enclosures on the legs of the tripod as shown.
