Vaisala WMT700 - Manual (Page 186)

User's Guide ______________________________________________________________________
Problem Probable Cause Remedy
WMT700 does not respond
to any commands. The communication profile is not
correct. Configure the communication
profile to match the host
communication profile.
The wiring might be incorrect. Check the wiring, see section
Wiring on page 77
Connection works but data
messages are not available. The command has been mistyped. Use the ERRORS command to
fetch the error messages from
WMT700.
See section ERRORS — Get
Error Codes and Counts on page
116.
Data messages are not in
the expected format. The selected data message is not
correct. If you are using automatic
messages:
Check the selected data
message with the G command. If
necessary, set a new value for
the autoSend parameter.
If you are using polling:
Check that you are using the
correct data message number in
the polling command, see Table
40 on page 128.
Some items are missing
from the data messages. The configured data message does
not contain all the required items. Define the data message again
with the required items. See
section Parameter Handling
Commands on page 111.
Configuration commands do
not work. WMT700 is in measurement mode. Switch from measurement mode
to configuration mode. See
section Communicating with
Terminal Software on page 107.
WMT700 sends an error
message as a response to a
command. For probable causes, see section
Error and Event Messages on page
185. For remedies, see section Error
and Event Messages on page
185.
No signal is present on
analog outputs. Analog output has been disabled. Enable analog output with the
aout1_mode and aout2_mode
parameters. See Configuration
Parameters on page 118
Automatic data messages
are not received although
parameters have been set
correctly. WMT700 is not in continuous
measurement mode. Initiate continuous measurement
with START command. See
START — Start Continuous
Measurement on page 115.
Data from WMT700 is
temporarily lost. The data logger and wind sensor are
not in the same operating mode
(polling or automatic transmission
mode). Make sure that the data logger
and wind sensor are both in
either polling or automatic
transmission mode.
Data messages are not
received. Baud rates of the data logger and
wind sensor do not match. Change the baud rate so that it is
the same in the data logger and
wind sensor.
Parameter does not change
after S command has been
given. The parameter requires reset before it
becomes valid. Check Appendix D Configuration
Parameters on page 205 if reset
is required before the parameter
is changed.
