o
USB communications: use the EC100 USB cable to connect a PC to the base of the
EC100 enclosure.
o
RS-485 communications: use cable CABLE3TP-L for lengths less than 500 ft. The
connector on the EC100 panel labeled RS-485 displays which terminals are for
receiving and transmitting.
o
Analog output: use cable CABLE4CBL-L or CABLE2TP-L. Again, the customer
specifies the length of this cable at time of order. The connector labeled Analog
Outputs on the EC100 panel indicates where each wire should be connected (CO

O, and two ground connections).
7. Wire power and ground (power reference) cable CABLEPCBL-L to the EC100. Feed the
cable through one of the cable port openings in the base of the EC100 enclosure and
attach the ends into the green EC100 power connector. Plug the connector into the female
power connector on the EC100 panel. Ensure that the power and ground ends are going to
the appropriate terminals labeled 12V and ground, respectively.
8. Connect the power cable to a power source. The power and ground ends may be wired to
the 12V and G ports, respectively, of a Campbell Scientific data logger or to another 12 VDC
source.
9. Once power is applied to the EC100, three status LEDs on the EC100 panel will illuminate.
The power LED is green and the sonic and gas LEDs are orange until the unit has warmed
up and is ready to make measurements at which time the LEDs become green. If, after
several minutes, the LEDs turn red, a diagnostic flag has been detected. Check the
individual diagnostic bits to determine the specific fault. Diagnostics may be monitored
using the Status Window of
ECMon , the user interface software included with the IRGASON
(see Settings (p. 19)), or with a data logger (see Data collection and data processing (p. 42)).
The diagnostics may reveal that the unit needs service such as cleaning the optical windows
on the gas analyzer, clearing the sonic transducers of ice or debris, etc. (see
Maintenance
(p. 31)).
7. Settings
Operation of the IRGASON can be customized by changing settings. Factory defaults work well
for most applications, but the user may adjust the settings with a PC using either the Campbell
Scientific
ECMon software (see ECMon (p. 24)) or Device Configuration Utility (see Device
Configuration Utility (p. 26)), or with a data logger using the
EC100Configure()
instruction
(see EC100Configure() instruction (p. 49)).
