Troubleshooting
The TRITON+ flow monitor co ntains several different components
that perform many different functions. Since a malfunctioning
component increase s the risk of losing d ata, isolating the problem
component is essential to performing troubleshooting activities
efficiently. Minimizing monito r downtime is critical.
Consider the following when trying to isolate the component or
subsystem exhibiting the prob le m:
 Problems affecting only o ne of the sensor subsystems are
usually caused by one subsystem alone. The problem may exist
in the monitor processor 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 communications, clock readings, time stamps,
and data storage intervals usually arise from faulty processor
board components, 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
prob le ms with the field unit or c omponent cabling. Failures
occ urring o n t he inside (i.e., between a connector and the
printed circ uit b oard) may a r ise from problems with the
processor board.
Note: If possible , c ollect all monitor data prior to
swapping sensors or troubleshooting a monitor to prevent
possible data loss. In addition, remove the monitor from
the manhole before disconnecting cables from the monitor
to avoid possible hazards.
