6.3.6 Wire Power and Ground the EC100
1.
Feed cable CABLEPCBL-L (pn 21969-L) through
Cable 2
at the bottom
of the EC100 enclosure (see FIGURE
) and attach the ends into the
green EC100 power connector (pn 3768).
2.
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.
3.
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 datalogger or to another 12 Vdc source.
Once power is applied to the EC100, three LED status lights on the EC100
panel will illuminate. The power LED will be green if the power supply
voltage is between 10 to 16 Vdc. The gas LEDs will be orange until the gas
head has warmed up. The sonic LED will be red while the sonic acquires the
ultrasonic signals. The sonic and gas LEDs will turn green if there are no
diagnostic warning flags. Three green LEDs indicate that the instrument is
ready to make measurements.
The EC150 power-up sequence takes under two minutes to complete. During
power up the gas LED will be orange. If after two minutes the gas LED turns
green, power-up sequence has been completed successfully. If the gas LED
turns 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
(see
), the user interface software included with the
EC150 (see Appendix
(p. A-1)
), or with a datalogger. The
diagnostics may reveal that the unit needs to be serviced (for example, cleaning
the optical windows on the EC150, cleaning the CSAT3A transducers of ice or
Maintenance and Troubleshooting
(p. 31)
).
6.4 Data Collection and Data Processing
Data from the EC150 is collected through the EC100 and then archived onto a
datalogger. A common instrument configuration is to program a datalogger to
retrieve and collect raw data from the EC150, to be used for post processing,
for which various programs have been developed.
