Troubleshooting
The RainAlert II 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
exhibiting the problem:
 Problems affecting only one of the components are usually
caused by one component alone. The problem may exist in the
board, communications, tipping bucket, or cabling.
 Problems affecting more than one component usually can be
traced to a problem with the processor, power source, or
communication lines. Problems in one component can create
problems in other components 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
processors, 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 board) may arise from problems with the board
or its cabling.
Note: If possible, collect all monitor data prior to
swapping a tipping bucket or troubleshooting a monitor to
prevent possible data loss. Swapping a tipping bucket or
battery pack does not result in stored data loss.
