RailNET In a NEMA Enclosure Installation Manual
RailNET In a NEMA Enclosure allows for easy installation by using mindful packing techniques.
Site Considerations
Pre-construction
- Find the transducer location first. This is the center of the site. The center of the transducer must be located between two ties. This allows the cable at the bottom of the transducer to enter the Carflex conduit without binding.
- Find the tower locations. Since the center of the antennas and the center of the transducer must line up, the towers will be offset from the transducer. (The antennas mount to the side of the tower.)
Areas to Avoid
Comet Electronics recommends that the following site areas are avoided. Use this list as a guide only. Since all installations are unique in some manner, avoiding these areas is not always possible. A survey of each site should be done to determine preferred equipment locations, conduit runs, and antenna configuration based upon the particular application. The user and the system integrator must ensure correct and accurate system operation in the event the areas described below cannot be avoided.
- Large metallic objects and obstructions in close proximity to the reading area
- Areas where reverse train movements occur
- Areas where train switching moves occur
- Areas where “building” moves occur (dropping and adding cars)
- Areas where train stoppage in front of reader systems is likely to occur
- Areas with severe or multiple curves in the track
- Switches
- Track joints
