Important notes regarding the use of Tyco TraceTek Fast Fuel Sensor and

TraceTek sensing cable:

•

Tyco TraceTek sensors must be installed as per manufacturer

recommendations.

•

Do not run the Rosemount 702 Transmitter for long periods (more than

two weeks) with a Tyco fuel sensor in the leak state as this will more

rapidly deplete the power module.

imperative that both PV and SV be mapped to the host system so as to make

a good interpretation of the condition and status of the leak detector.
