4. Positioning the sensors inside the shield. Before placing the sensors in the shield, attach
a piece of tape to each sensor and mark one with a “1” and the other with a “2” using a
permanent marker so it easy to identify the sensor number on the Climate Maintenance
Log form (Appendix A.3. Climate Protocol Maintenance Log). With the sensor cables
secured, slide the sensor into one of the large plastic retaining brackets and push to the
bottom of the tube until it cannot go any further (remove the small retaining brackets to
create more space). Coil the sensor cable into 2-3 loops and secure at a couple of places
using plastic cable ties or electrical tape, so the cable does not interfere with the fan once
the shield is assembled. Repeat the same process with the other sensor and position the
sensors so they don’t touch the walls of the tube directly (they can touch each other).
5. Mount the shield on a cross arm. The top of the shield can be mounted at the end of a
sensor cross arm (CM206) and at a height of 2 m from the ground. Slide the shield into
the cross arm and tighten the Phillips screws so it does not slide. Watch the “Mounting
the temperature/RH sensors” video in the Climate Protocol section of the TEAM portal
(http://www.teamnetwork.org/en/protocols/threat/climate) for more information.
6. Assemble the rest of the shield. Position the shield tube on the base of the roof and
secure with the four clamps. Connect the sensor cables (10 pin connector next to the
tube). Route these cables along the cross arm and down to the enclosure. Secure the
cables to the cross-arm and the tower using plastic cable ties.
7. Connect the terminals from the shield to the CR1000. Remove the U-shaped pre-wire
connectors if there are any at the end of the cables. Using a cable cutter, strip about 1 cm
of the plastic shield to expose the bare cable. Using the diagram in Figure 12 connect the
cables to the correspondent connectors in the data logger (both the American and
European versions use the same connections).
8. Connect the power and tachometer cables to the data logger. Following the same
process to connect the power cable (which carries the tachometer signal) in the
appropriate slots in the data logger (make sure the power cable goes into the SW-12 V
slot). Use Figure 15: as a reference.
