MARINE TECHNOLOGIES Bridge Mate RadaScan Manual

Hazardous Area Installations

Special Conditions of Use

Bridge Mate™ RadaScan transponders are classified as intrinsically safe apparatuses and associated apparatuses, and can be used:
· in Zones 1 and 2 with flammable gases and vapors belonging to gas groups IIA/B. (Reference: EU ATEX directive 94/9/EC,
Annex II, 1.06)
· in Class I, II and III, Div 1 hazardous (classified) locations. (Reference: USA UL STD 913)

Instructions for Safe Use

· Bridge Mate™ RadaScan transponders contain no user-serviceable parts. They can only be serviced by Marine Technologies or other
approved service representative.
· The front or back panels of the transponder should never be removed in a hazardous area.
· Transponders are only certified for use in ambient temperatures between -13° F to 131° F (-25° C to 55° C) and should not be used
outside this temperature range.
· The front cover of the transponder presents a static hazard and should only be cleaned using a damp cloth.

Maintenance and Servicing

Bridge Mate™ RadaScan transponders do not contain any user-serviceable parts. The
unique transponder ID is programmed at the factory and can only be changed by the
manufacturer.
The transponder will operate continuously for one year from the date it was switched on.
The battery replacement date is written on a label affixed to the back of the transponder.
Transponders must be serviced annually by Marine Technologies or other approved
service representative.

Switching the Transponder On or Off

Bridge Mate™ RadaScan transponders are always switched on before they are shipped. If
the transponder needs to be switched on or off, follow these steps:
Note: The front or back panels of the transponder
should never be removed in a hazardous or wet area.
1. Move the transponder to a dry, non-hazardous area.
2. Remove the back cover from the transponder.
3. Move the ON/OFF switch to the required position.
4. Replace the back cover, ensuring that the seal is good.

Positioning and Mounting

The location, range and orientation of the transponders in relation to the sensor have a significant effect on the tracking performance
of the Bridge Mate™ RadaScan system, and hence on the quality of the position data sent to the DP system.
RadaScan is a radar-based system. Metallic structures reflect the microwave beam transmitted by the sensor, and can cause multipath
interference, where ghost images are reported by the system. However, this unwanted phenomenon can be prevented by carefully
positioning the transponders according to the guidelines on the following page.
