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
problems will require a site visit. When this is necessary, inform
the analyst any time a field crew is enroute to a monitor location to
troubleshoot problems so that the analyst can attempt to collect the
monitor data before they arrive. If the problem is a faulty monitor
and the analyst cannot collect the data remotely, replace the monitor
and deliver the faulty monitor to the office so the analyst can
attempt to collect the data directly. If the analyst is still unable to
collect the data from the monitor, send it to ADS for repair.
This chapter provides general guidelines for troubleshooting and
correcting problems with the FlowAlert monitor, the pressure depth
sensor, or the float switch(s).
