    OVERVIEW CHAPTER 1: INTRODUCTION Figure 1-1: Note icons used in the documentation NOTE CAUTION DANGER The standard note icon emphasizes a specific point or indicates minor problems that may occur if instructions are not properly followed. The caution icon indicates that possible damage to equipment or data may occur if instructions are not properly followed.

  • Page 7: Description Of The Dgt System Units

    CHAPTER 1: INTRODUCTION OVERVIEW The entire round trip time from trip initiation at the substation into the DGT-U to confirmation from the DGT-D occurs in under 150 milliseconds. The integrity of the Trip Status state is maintained through the use of a 32-bit CRC calculation. The CRC prevents the erroneous or malicious manipulation of the Trip Status so that only true data is acted upon.

    MECHANICAL INSTALLATION CHAPTER 2: INSTALLATION Installation Considerations For a successful installation, careful thought must be given to selecting the proper site for the DGT-D and its antenna system. The location must be able to support antenna mounting at a height and in a direction that provides an unobstructed radio signal transmission path to associated DGT sites.
  • Page 17 CHAPTER 2: INSTALLATION MECHANICAL INSTALLATION Prepare the mounting surface for the fasteners to be used. (If using lag screws, a small pilot hole at each mark will allow easier starting of the screw.) Insert the 4 mounting screws and tighten them securely. Do not over-tighten. POLE MOUNTING Standard pole mounting requires the use of two pole-mount adapters (P/N 82-1743A01).

    CHAPTER 2: INSTALLATION ANTENNA AND FEEDLINE INSTALLATION Antenna and feedline installation DGT units are ordered with an antenna and feedline package, ready for installation at the station site. A number of standard feedline lengths are available. The length necessary to connect the station antenna to the DGT is determined during the site survey.

  • Page 22: Maintaining Regulatory Compliance (Rf Output Power)

    RF level from the transceiver is dependent on the gain of the antenna and feedline loss. In all cases, the maximum EIRP from the antenna must not exceed 36 dBm. Contact GE Multilin if assistance is required in determining the maximum output power setting.
