YSI Profiler System USER Manual
We recommend that you arrange some way to verify a working communications system on site.
With a cellular modem or any wireless setup in the Profiler system and a cell phone, you could
collaborate with a colleague to check communications between remote and base sites. The base
user can use LoggerNet to initiate actions that are prearranged. If there are problems, some
troubleshooting can be done on site by using cell phone vocal communication in combination.
If you have problems and they are not obvious, consult your communications manual and double
check setup configuration during configuration of your Profiler system.
6.3 Maintenance – Servicing the Sonde
Refer to your sonde manual for specific care and maintenance procedures. Care and
maintenance depend on both the sonde model and the sensors you have installed. Other than the
obvious visual inspections and cleaning, calibration frequency varies from sensor to sensor.
There are some specific concerns when servicing a sonde used in the YSI Profiler. These points
are made below.
As previously mentioned when the time comes to disconnect the sonde from the winch for
calibration or service you must wait for the profile to end. If that is not possible, then you must
turn power off to the winch motor.
Ideally sonde servicing should take place by rotating a spare sonde into service while the system
is in between profiles (idle at Park). When this is not possible and the sonde must be removed
for on-site calibration, then the system needs to be stopped temporarily.
Connect a lap top to the Controller Assembly using the Diagnostic Cable. Start LoggerNet™
and connect to the station. Use the Ports and Flags function to track activity. At this point Flag
2 should be OFF (low). No other flags or ports should come ON except for Port 8 which will
turn ON briefly every 20 seconds. If the Ports are flickering ON and OFF, then the system is
probably in the middle of a profile sequence. Do not disconnect the sonde if this is the case.
Turn Flag 2 ON (high). This puts the Profiler system into Setup Mode keeping it in idle mode
for the duration of the service procedure.
Once sonde servicing is complete, connect the sonde to the winch cable and verify proper sonde
operation using the LoggerNet™ flags
.
If you are satisfied with the tests, you can exit Setup mode by setting Flag 2 OFF (low). If you
want to start a profile immediately, then set Flag 5 ON (high). Otherwise the profiling routine
will be determined by the clock and you may be required to wait for some time.
IMPORTANT:
YSI recommends that after you service a sonde you should start a profile and verify
sequence operation before departing the remote site.
