Troubleshooting
The FlowShark flow monitoring system contains several different
components that perform many different functions. Since a
malfunctioning component increases the risk of losing data,
isolating the part containing the problem quickly is essential to
performing troubleshooting activities efficiently. Minimizing
monitor downtime is critical.
Consider the following when trying to isolate the component or
subsystem exhibiting the problem:
 Problems affecting only one of the sensor subsystems are
usually caused by one subsystem alone. The problem may exist
in the board, sensor (or other input device), or cabling.
 Problems affecting more than one subsystem usually can be
traced to a problem with the processor board, power source, or
communication lines. Problems in one subsystem can create
problems in other subsystems when the power source or
communication lines are faulty.
 Problems with communication lines, clock readings, time
stamps, and data storage intervals usually arise from faulty
processor boards, incorrect information entered on the user's
PC, or low batteries.
 Failures occurring outside a connector (i.e., between a
connector and the field input or output device) may arise from
problems with the field unit or component cabling. Failures
occurring on the inside (i.e., between a connector and the
printed circuit boards) may arise from problems with boards or
their cabling.
Note: If possible, collect all monitor data prior to
swapping sensors or troubleshooting a monitor to prevent
possible data loss. Swapping sensors or batteries does not
result in stored data loss. In addition, remove the monitor
from the manhole before disconnecting cables from the
monitor to avoid possible hazards.
