  • Page 9: Chapter 1 Introduction

    The SmartScanIS is modular and firmware driven. Hardware and firmware can be changed to meet the unique needs of a given railroad. Thus, some of the components that make up a SmartScanIS differ from railroad to railroad.
  • Page 10  Communications sent to the Harriman Dispatch Center When the SmartScanIS detects a defect, it informs the crew of the affected train. This is done by a voice transmission over an assigned radio channel. The voice is computer generated from previously digitized human speech. It tells the crew the milepost of the reporting SmartScanIS, a warning that a defect has been detected, and other defect-related information.

  • Page 11: Cautions

    STC. So too are the correct use and maintenance of all or part of the SmartScan system. Therefore, the installer, user, and maintainer must assume the risk of any injury that might occur during installation, use, and maintenance of all or part of the SmartScan system.

  • Page 26: Auxiliary-Alarm Detectors

    2.3 Auxiliary-Alarm Detectors The standard SmartScanIS can support input from as many as four external alarm devices. Any device that provides an open set of relay contacts upon alarm detection can be supported by the system. The system responds to an open contact by announcing the defect and the axle number nearest the defect.

    9.11 Checking for Hot Bearing To generate a test train to check for hot bearings: STC recommends that you use the calibrated heat source (2100-810NG) only when the outside (ambient) temperature is above 0°F (-18°C) and below 90°F (32°C). If you must use it at other times, do so only when the needle is centered on the front of the temperature meter.

    It is during the scanning process that the system checks for defects. The SmartScanIS is equipped with one of two primary means of train arrival detection, which are the track circuit or the advance transducers. In case of a failure in the primary detection method, the gating transducers act as a backup to detect train arrival.

  • Page 192: Serial Ports; Rs232 Devices

    11.1 Serial Ports; RS232 Devices There are two serial ports on the System Interface board that connect the SmartScanIS to RS232 devices. They are labeled P8 and P10 on the board. P10 is COM2 and P8 is COM3. COM1 functions as the conduit for communications with RS485 devices and is configured for this protocol when systems are shipped.

  • Page 193: Main Menu

    COM3 is the only port that displays anything as the system boots up. Consequently, you must use it if you want to see what's happening following a power-up or reset. Because COM1 and COM2 already have functions allocated to them, STC recommends COM3 as the only serial port for use with the serial interface.

    C.5 Auto-Calibration Selection of the Auto-Calibration option places the system in autocalibration mode. The SmartScanIS self-calibrates its pyrometer interface circuitry. You need only put a preheated calibrated heat source on a scanner and place the system in autocalibration mode. The system then scans all pyrometer inputs until the signal from the calibrated heat source is located.
