FIGURE 6-6. Bottom of EC100 enclosure
Do not connect or disconnect the EC155 gas analyzer head
or CSAT3 sonic head while the EC100 is powered.
a. Connect the EC155 gas analyzer head. Begin by removing the black
rubber cable entry plug (pn 26224) on the bottom right of the EC100
enclosure. (This plug can be stored in the mesh pocket of the enclosure).
Now insert the cable entry plug that is attached to the large cable of the
EC155 gas analyzer head into the vacant slot. Push the connector at the
end of the cable onto its mating connector (labeled Gas Analyzer) and
tighten the thumbscrews (see FIGURE 6-6). The EC155 gas analyzer
cable is approximately 3 meters in length.
b. Connect the EC155 sample cell cable. Unscrew the sample cell connector
cover, which is found on the bottom of the EC100 enclosure. Insert the
12-prong sample cell cable connector into the female connector on the
enclosure and screw it firmly in place. The EC155 sample cell cable is
approximately 3 meters in length.
c. Connect the CSAT3A sonic head (skip this step if not using the CSAT3A).
Similar to (a), begin by removing the black rubber cable entry plug found
on the bottom left of the EC100 enclosure. Insert the cable entry plug on
the CSAT3A cable into the slot and connect the male end to the female
connector labeled Sonic Anemometer on the EC100 electronics (see
FIGURE 6-5). Tighten the thumbscrews. The CSAT3A cable is
approximately 3 meters in length.
