Troubleshooting
The TRITON+ flow monitor contains several different components
that perform many different functions. Since a malfunctioning
component increases the risk of losing data, isolating the problem
component 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:
z Problems affecting only one 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.
z 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.
z 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.
z 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 board) may arise from problems with the
processor board.
Note: If possible, collect 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.
Some problems that occur will not require a site visit, such as
incorrect equipment identification numbers or other system
parameters the user can re-enter on the local PC. However, some
