tab (refer
to Section 8.1.6 , Testing the Measurement Operation of the CRVW3
(p.
27)
, and Section 8.2.8.2 , Validation with DevConfig
(p. 47)
)
•
Watch the LED activity as the device operates to ensure proper
function (see Section 8 , Installation of Individual CRVW3 Stations
(p.
15)
)
You should be aware of the siting and installation issues discussed in Section
8.2 ,
Field Deployment of the CRVW3
(p. 33)
, and check them for any
discrepancies. You should observe the solar panel operation (–RC option) to
ensure it is charging the battery properly. You can also double-check antenna
operation using a temporary base station radio and a laptop running LoggerNet
(see Section 10 ,
Complex (Large) Radio Networks
(p. 58)
). Using the Terminal
mode of the CRVW3 from DevConfig can also be used to perform maintenance
(see Appendix B , Terminal Mode from Connect Screen or DevConfig
(p. B-1)
).
13. Troubleshooting CRVW3 Networks
By following the tasks outlined in Section 11 , Operation of CRVW3 Networks
(p. 88)
, and Section 12 ,
Maintenance of CRVW3 Networks
(p. 96)
, for operating
and maintaining your network of CRVW3 stations, you can identify problems
with the system when they emerge or very soon after they occur.
The Status Monitor is a key tool for identifying that a problem in the system
exists (see Section 11.1 ,
Monitoring Automatic Data Collection
(p. 88)
, for
guidance about using Status Monitor ). Some common indicators that
something is wrong with a station are:
•
Automatic (scheduled) collection is not working as shown by the
Status Monitor
or Table Monitor
• You can’t connect to the station in the LoggerNet Connect Screen
•
Clock checks ( Setup Screen ) are not working
• Manual collection doesn’t work ( Custom Collect and Collect Now )
• You can’t view the Station Status ( Summary and Status Table)
•
The station is able to communicate, but the data that is collected from
that station has problems
You should troubleshoot problems as soon as possible after they arise. Some
clues relating to the source of the problem can change (become more obscure)
over time. Small problems can often escalate into larger ones, due to cascading
consequences.
Troubleshooting a part of the system that has never worked is strongly related
to the installation process. Review Sections 7 through 10 as a first step of
investigation in such cases.
When a problem arises in a system area that used to work but has recently
stopped working, the main question to ask is “What changed?” What changed
in the system to cause the station to stop operating? When did the failure
begin? Examine key aspects of the system and its recent maintenance history to
obtain clues about changes made to the system. Sometimes a change to the
system that seems harmless or unrelated turns out to be the cause of the
trouble.
