monitor, pressure depth sensor, and
float switches are designed for dependability and durability, all
electronic devices are vulnerable to wear, malfunction, or failure,
particularly in a harsh sewer environment. However, many system
problems can be avoided altogether by performing routine
maintenance and inspections. The design of the monitor enables the
user to perform general diagnostics and troubleshooting to prevent,
isolate, and correct many problems easily. These serve to minimize
unnecessary monitor downtime and data loss.
This chapter provides routine maintenance instructions as well as
general diagnostic and troubleshooting guidelines for isolating and
correcting monitoring system problems.
Warning: Remove the monitor from the manhole before
replacing the battery packs or performing service activities
which may involve disconnecting cables from the monitor.
In addition, disconnect telephone service at the network
interface box before disconnecting cables from the monitor
lid. These activities help prevent possible shock or injury
to personnel as well as damage to the equipment during
service visits at the monitor location.
