FCC RULES COMPLIANCE

The equipment covered in this manual has been tested and found to comply with the

limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits

are designed to provide reasonable protection against harmful interference when the

equipment is operated in a commercial environment. This equipment generates, uses,

and can radiate radio frequency energy and, if not installed and used in accordance

with the instruction manual, may cause harmful interference to radio communications.

Operation of this equipment in a residential area is likely to cause harmful interference

in which case the user will be required to correct the interference at his expense.

ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS

Static electricity can damage electronic circuitry, particularly low voltage

components such as the integrated circuits commonly used throughout the

electronics industry. Therefore, procedures have been adopted industry-wide which

make it possible to avoid the sometimes invisible damage caused by electrostatic

discharge (ESD) during the handling, shipping, and storage of electronic modules

and components. Siemens has instituted these practices at its manufacturing facility

and encourages its customers to adopt them as well to lessen the likelihood of

equipment damage in the field due to ESD. Some of the basic protective practices

include the following:

•Ground yourself before touching card cages, assemblies, modules, or

components.

•Remove power from card cages and assemblies before removing or installing

modules.

•Remove circuit boards (modules) from card cages by the ejector lever only. If an

ejector lever is not provided, grasp the edge of the circuit board but avoid

touching circuit traces or components.

•Handle circuit boards by the edges only.

•Never physically touch circuit board or connector contact fingers or allow these

fingers to come in contact with an insulator (e.g., plastic, rubber, etc.).

•When not in use, place circuit boards in approved static-shielding bags, contact

fingers first. Remove circuit boards from static-shielding bags by grasping the

ejector lever or the edge of the board only. Each bag should include a caution

label on the outside indicating static-sensitive contents.

•Cover workbench surfaces used for repair of electronic equipment with static

dissipative workbench matting.

•Use integrated circuit extractor/inserter tools designed to remove and install

electrostatic-sensitive integrated circuit devices such as PROM’s (OK Industries,

Inc., Model EX-2 Extractor and Model MOS-40 Inserter (or equivalent) are highly

recommended).

•Utilize only anti-static cushioning material in equipment shipping and storage

containers.

For information concerning ESD material applications, please contact the Siemens

Technical Support Staff at 1-800-793-7233. ESD Awareness Classes and additional

ESD product information are also available through the Technical Support Staff.

SECTION 1

INTRODUCTION

1INTRODUCTION

1.1 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.

1.1.1 Current Sensor Board

The current sensor board is designed to monitor up to three lamps. The main board

contains all the circuit components needed to create the digital outputs that

represent the state of the lamps, including the sensors themselves. A Current

Sensor Adapter board may be used to interface the lamp circuit to the current

sensor board. Figure 1-1 displays the current sensor module.

Document No.: SIG-00-11-10 Version: A.1

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. This is accomplished in a relatively

simple, easy, and minimally disruptive manner. Figure 1-2 shows the current sensor

adapter board.

2.1 Installation Overview

The current sensor system consists of two components, the current sensor and an

optional current sensor adapter board. A typical three lamp signal installation is

shown in Figure 2-1.

WARNING

VERIFY ALL COMPONENTS AND WIRING ARE PROPERLY

INSTALLED AND MEET THE RAILROAD'S OR AGENCY'S

APPROVED WIRING OR INSTALLATION 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.

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. Figure 2-2 displays a current sensor adapter mounted on a signal

terminal block. The optional current sensor adapter cab be installed on each lamp

terminal.
