8. Troubleshooting and Maintenance
Troubleshooting
The following checklist will help in troubleshooting problems:
Problem Possible Cause
No data Faulty wiring – check all wiring and terminations
No power – check fuse in the data recorder and power at
sensor. There is no fuse in the sensor itself.
Wrong address requested -- make sure the data recorder is
set up to request data at the proper address
Wrong address set in sensor -- use the identify command to
make sure the sensor is responding to the proper address, if
not double check internal address dip switches since on
power-up they override any address set by the software.
Command or address is wrong case – all ACCUBUBBLE
commands are capital letters, make sure address is proper
case and commands are upper case.
Garbled data Multiple sensors set to the same address -- check address
settings of all SDI sensors. Remove all other sensors from
the recorder and add them one at a time.
Command issued to a wild card address (* or ?). Remove all
other sensors from the recorder and try again.
Erroneous data Wrong units selected -- use the M command and look at the
units field. Verify that the desired units are selected.
High unstable readings when bubbler is utilized – Unit has
not been configured for use at the site. Use the XPC and
XPT commands as described in Chapter 6 – Installation to
configure the unit for the site.
High unstable readings when bubbler is utilized – Water in
the orifice line. Use 0XPR+240! To purge line for four
minutes.
Low readings when bubbler is utilized – Check for leaks in
the system by using the XPL command.
Erroneous offset entered -- display the field calibration
offset using the M3 command and verify it. Re-calibrate the
offset.
Erroneous user scale and offset entered – display the user
scale and offset using the M3 command and verify.
CAUTION: Do not remove the microprocessor from the ACCUBUBBLE for
any reason. If there is a problem with the processor, please notify Sutron
Customer Service at (703) 406-2800. Only factory-trained personnel with
specialized tools can remove the microprocessor without damaging the unit and
the processor.
