Configuration
Parameter Adjustment
There are a number of parameters that are used to configure the radar for
different site conditions. These are changed by editing parameters. At the
time of writing, the parameters that the installer will need to update are:
- (1.0 to 30.0) Total manhole height (in meters).
- (0.0 to 20.0) This is the distance (in meters) from the manhole rim to the lid of the enclosure when installed.
Field Service
Important note: The BLU-X Radar has been designed as a single device. While
there are multiple components within the radar, the components are associated
with the serial number of the unit and they are not intended to be field
serviceable. If a BLU-X Radar device is not performing as expected, please
request authorization to return the device for replacement.
Normally maintenance of the unit involves the following few steps:
- Removal of the radar and support bar assembly from the sewer
- Inspection and removal of the tamper detection tag
- Visual inspection of the external surface of the radar enclosure
- Opening of the enclosure and inspection of the interior
- Inspection and replacement of desiccant
- Inspection and replacement of batteries
Step 1 above should be completed according to support bar service documentation. Steps 2-6 are addressed below.
Inspection and removal of the tamper detection tag:

Opening of the enclosure and inspection of the interior:
| No. | Description | Illustration |
|---|---|---|
| Orient the radar with the lid facing up and lift the integrated clasp to the |
side until the lid releases. Proceed to gently open the lid from the base of
the unit|
| Inspect the interior of the unit for evidence of water damage such as
pooling water, evidence of water stains, moisture in the interior, or other
signs of enclosure failure.|
Inspection and replacement of the desiccant:
| No. | Description | Illustration |
|---|---|---|
| The desiccant is located in the compartment opposite of the battery |
connectors. Remove the old desiccant packs and inspect the color indicator on
the packs to determine if the desiccant was consumed. Please estimate and
record how much the desiccant was consumed.|
| Replace with new packs of the same type.
Inspection and Replacement of Batteries:
Battery removal is described as follows:
| No. | Description | Illustration |
|---|---|---|
| Note: Please review the safety section in this document before attempting to |
replace batteries
| If you have not already done so, please disconnect the battery from the
telemetry board by separating the male and female battery connectors. Use
caution when separating the connectors.|
| Rotate the hinged telemetry assembly up to access the battery compartment.
Take care to avoid contact with wires and electronics. Make sure to use all
necessary safety equipment when accessing batteries.|
---|---|---
| Inspect battery packs and battery cables for signs of damage such as
corrosion, bloating, or discoloration. If any pack or cable appears to be
damaged, do not attempt to service the unit. Please place the unit in a safe
location, away from people and potentially flammable items then contact your
Xylem representative. If you cannot reach your representative and/or if you have identified a dangerous safety issue, please contact your local authority.
| If battery packs and cables appear to be in good condition, remove battery packs and safely discard, following all legal requirements.

Troubleshooting
Identifying an issue
Hardware Issue
Most issues are easily identified as hardware issues, such as:
- Low voltage Battery packs – as indicated by values on the Blu-X portal
- Moisture in the enclosure – evident without opening the enclosure by looking through the optically transparent lid. If the enclosure is opened, look for pools, droplets on surfaces, and corrosion of metal surfaces and connectors.
- Damage to enclosure – as indicated by cracks in the enclosure, missing pieces of the enclosure
- Damage to internal components – as indicated by loose or broken pieces in the enclosure, etc.
- Cable connectivity issues – as indicated by frayed cables or loose or disconnected cables.
If you identify a hardware issue, please return the device for service.
Configuration Issue
If the BLU-X Radar is reporting an incorrect water level, please double check
the configuration settings for the correct manhole height and radar offset
values.
Connectivity Issue
When deploying a new BLU-X Radar, if you find that data from the BLU-X Radar
are not visible on the BLU-X Portal and there are no signs of physical damage,
then it is possible that there is a wireless connectivity issue. The units
have been preconfigured for wireless connectivity and communication with the
BLU-X platform. Please reach out to your field service manager with the serial
number of the radar in question in order to receive further support.
Returning a device for service
If there is an issue which cannot be resolved or if the service technician has
identified a hardware issue, please disconnect the batteries if it is safe to
do so. Please request authorization to return the unit for replacement. You
will receive instructions to safely prepare and return the unit.
