ADS ForeSITE FS-UL-4G Manual
Maintenance and Troubleshooting
The device should be periodically checked to ensure no degradation or cracking of the housing
that could introduce water or moisture intrusion.
The desiccant packet should be changed during each battery installation. This may be required
more frequently in high humidity or moisture installations
Occasionally, debris or insects may become built up inside the cone of the ultrasonic
transducer. To clean, use a soft brush or cloth and isopropyl alcohol to clean the sensor. DO
NOT SCRUB the face of the transducer as this may damage the sensor.
If sensor readings are erratic, check the installation site to ensure no obstructions are in the
path of the sensor measurement and clean any build-up within the transducer cone.
If experiencing inconsistent data communication:
• Verify antenna connection
• Ensure proper sealing around antenna connection
• Check antenna cable for any damage
• Ensure antenna is not placed on or within 12 inches (304mm) of any large metal objects
and has a relatively clear path to local cellular towers.
