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.
The encoder ERT module is reporting an invalid read.
An encoder ERT module that has set the Last Good Read flag will
cause an Invalid Read to display in the FDM Consumption field.
Marginal readability due to water ERT module location
(for example, an ERT module deep inside a pit).
Consider reprogramming the ERT module 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.
