Maintenance
CAUTION
Radar RF Exposure Hazard. Although the RAVEN-EYE® microwave power level is very small (~15
mW) and is well below government stated exposure limits for uncontrolled environments, users of this
product should follow proper safety protocols for the handling of devices with radar frequency
transmitters. Avoid placing the head and other vital organ areas within the microwave beam (within 1
meter of the microwave aperture).
IMPORTANT NOTE:
Delicate Instrumentation. Handle with care to prevent damage to the microwave transmitter. Damaged
transmitters can result in higher signal power levels, which can interfere with essential terrestrial
microwave links.
5.1
Preventive maintenance
Monitor the inside pressure and humidity from the RAVEN-EYE
®
sensor, when the inside pressure falls to
atmospheric pressure and the humidity raises above 75%, return the instrument to manufacturer for inspection and
service.
Examine the RAVEN-EYE
®
sensor on an annual basis to look for corrosion or damage. Make sure that no swelling,
blistering, pitting or loss of material has occurred on the upper and lower portions of the main PU enclosure.
If the attached level sensor is used, examine the enclosure and the four M5 SS bolts. Inspect the cables and
connectors for any damage or corrosion and tighten all connectors in the system.
The only parts of the RAVEN-EYE
®
system that can be replaced by the user is the cable and the bail or sensor
mount assembly. If the sensor becomes defective, it must be replaced as a complete unit and/or returned to
FLOW-TRONIC S.A (refer to section 7 on page - 28 -).
Check the electrical connections
Examine the cable connectors on an annual basis for corrosion and tightness. If corrosion is found, clean and dry
the connectors to make sure that no moisture is on the connector pins. If corrosion is severe, replace the cables.
