On the DIN rail assembly, the UTB labeled DED is for the dragging-equipment detector. This
UTB protects the SmartScanNG² system from transients and surges, which can be induced
onto external wiring by lightning. The UTB has two rows of connectors. The wires from the
dragging-equipment detector terminate to the bottom row of connectors. The top row of
connectors is prewired at the factory to TS4 on the System-Interconnect board.
Correct polarity need not be observed when connecting the wires from the detector. One wire
from the detector should be connected directly below the existing white wire at the top of the
UTB, and the other wire should be connected directly below the existing black wire at the top
of the UTB.
9.9.4 High-Load/High-Wide Detector
Some systems use high-load detectors. Others use high-wide detectors. If your site doesn't
use either of them, skip the instructions below and go to the next section.
When used, there is one high-load/high-wide detector per track, each having two wires.
At double-track sites, the wires from the high-load/high-wide detector on track1 connect inside
the leftmost SmartScanNG² enclosure. The wires from track2 connect inside the rightmost
SmartScanNG² enclosure.
On the DIN rail assembly, the UTB labeled HIGH is either for the high-wide detector or the
high-load detector. This UTB protects the SmartScanNG² system from transients and surges,
which can be induced onto external wiring by lightning. The UTB has two rows of connectors.
The wires from the high-load/high-wide detector terminate to the bottom row of connectors.
The top row is prewired at the factory to TS4 on the System-Interconnect board.
