  • Page 7: Introduction

    INTRODUCTION SECTION 1 INTRODUCTION INTRODUCTION General The WIU (Wayside Interface Unit) current sensor is a component of the VIU and iVIU product lines. The WIU current sensor monitors signal lamp current to report if the lamp is off, on, or flashing. In PTC applications the current sensor monitors the energized state of the wayside signal lamps, and the signal aspect information is transmitted by the WIU to the locomotive.
  • Page 8: Current Sensor Adapter Board

    INTRODUCTION 1.1.2 Current Sensor Adapter Board The current sensor adapter board enables easy rerouting of the existing lamp wires through the sensors. By disengaging a single wire from its terminal and installing the small current sensor adapter board in its place, an extension loop (pre-wired through the sensor) is added to that lamp wire.

    DIAGRAM. FAILURE TO DO SO MAY LEAD TO INCORRECT OR UNSAFE OPERATION OF THE SIGNAL SYSTEM. CAUTION SIEMENS MOBILITY, INC. STRONGLY RECOMMENDS INSTALLING PRIMARY SURGE PROTECTION ON EXTERNAL LINES CONNECTING TO THE VIU. NOTE The WIU Current Sensor is not intended to be used for current sensing of Pulse Width Modulated (PWM) lamp detection.
  • Page 10: Current Sensor Adapter Installation

    INSTALLATION 2.1.1 Current Sensor Adapter Installation The current sensor adapter is designed to retrofit existing signal control points and make them PTC-ready with minimal effort. Figure 2-1 shows the comparison of an existing terminal board and a modified terminal board with the current sensor adapter installed.
  • Page 11: Current Sensor Wiring

    INSTALLATION 2.1.2 Current Sensor Wiring The wiring installation of the current sensor is shown in Figure 2-3 below. Lamp wiring is connected to the current sensor input connector J1. The input wires may be existing lamp wires or wires from the optional adapter board. Battery and the Vital Test Current Output are connected to J3.
  • Page 12: Current Sensor Output Connection

    INSTALLATION 2.1.2.1 Current Sensor Output Connection The current sensor output (J2) is connected using a shielded cable. The shield is terminated at the current sensor output only as shown in Figure 2-5. Belden 9939 or equivalent cable is recommended. CAUTION USE CARE TO ENSURE THE ELIMINATION OF ANY FOREIGN ENERGY SOURCES.
  • Page 13: Surge Protection

    Siemens Mobility, Inc. strongly recommends installing primary surge protection on external lines. A typical installation incorporating a surge suppressor on the wiring going to the signal lamp is shown in the figure below. Siemens Mobility, Inc. strongly recommends this type of installation.
  • Page 14: Current Sensor Module Expansion

    INSTALLATION 2.1.4 Current Sensor Module Expansion Multiple Current Sensor modules may be connected together to provide more inputs while reducing the number of individual power and test wire connections. To install an expansion module, insert J3 of the expansion module into J4 of the main module as shown in Figure 2-7.
  • Page 15: Threshold Settings

    INSTALLATION 2.1.5 Threshold Settings The current sensor module has adjustable threshold settings for each input. The settings are adjusted via DIP switches located on the front of the unit. The DIP switch settings are shown in Figure 2-9. WARNING IT IS THE RAILROAD'S OR AGENCY'S RESPONSIBILITY THAT THE INSTALLATION IS FULLY OPERATIONALLY TESTED TO ENSURE SAFETY.
