Proprietary and Confidential
This chapter provides the information to help you troubleshoot issues related to the 100W and 100WP ERT
modules.
The following table describes possible issues and provides suggested actions to resolve the issue.
Issue
Action
Cannot program the ERT module. Check the programming device and software version. Program ERT modules using
the FC300 handheld computer running Field Deployment Manager (FDM)
software.
Cannot read the ERT module. An ERT module that is not programmed will not transmit an SCM. Reprogram the
ERT module and perform a reread. If an ERT module is not initially programmed, it
will not bubble-up and listen for an SCM.
Marginal readability due to water ERT module
location (for example, an ERT module deep
inside a pit).
Consider reprogramming the endpoint for Hard-to-Read (H2R) mode. This
increases the output power to Fixed Network levels.
Note This mode will reduce battery life.
The ERT module in a Fixed Network is not
reporting.
Perform a Check ERT and verify the ERT module is in FN mode. If the CCU's
pathway is obstructed, consider including an 8-channel repeater. Systems that utilize
Fixed Network v4.0 software and a CCU100 may require a Repeater 100.
The handheld programmer is locked up and
button presses produce no response.
Soft boot the handheld by pressing and holding buttons A and B until the screen
fades. Release the buttons and allow the handheld to reboot.
