MANUAL SPECIAL NOTATIONS

In the Alstom manuals, three methods are used to convey special informational notations. These notations are warnings, cautions, and notes. Both warnings and cautions are readily noticeable by boldface type and a box around the entire informational statement.

Warning

A warning is the most important notation to heed. A warning is used to tell the reader that special attention needs to be paid to the message because if the instructions or advice is not followed when working on the equipment then the result could be either serious harm or death. The sudden, unexpected operation of a switch machine, for example, or the technician contacting the third rail could lead to personal injury or death.

An example of a typical warning notice follows:

WARNING

Disconnect motor energy whenever working on switch layout or switch machine. Unexpected operation of machine could cause injury from open gears, electrical shock, or moving switch points.

Caution

A caution statement is used when failure to follow the recommended procedure could result in loss or alteration of data. A typical caution found in a manual is as follows:

CAUTION

Changing session date and time to earlier values may affect the ability of the

History Window to store data correctly.

Note

A note is normally used to provide minor additional information to the reader to explain the reason for a given step in a test procedure or to just provide a background detail. An example of the use of a note follows:

Note: This step should be done first to validate the correct information is used.

Vital Printed Circuit Boards

SECTION 1 – VITAL PRINTED CIRCUIT BOARDS

1.1 INTRODUCTION

This manual describes the Printed Circuit Boards used to provide Vital functionality in the iVPI System.

See Alstom publication P2521B, Volume 2, Section 2, for the Vital and Non-Vital PC

Board Keying.

WARNING

iVPI contains special safety circuit components which must only be replaced by components specified by the Alstom part number.

These original-design replacement parts are manufactured to the same standards as the original parts; their performance being verified. The use of replacement parts that are not of the same Alstom part number could potentially impair the safe performance of the system.

The railroad or transit system authority and the manufacturer of an aftermarket (i.e., non-Alstom designated) part assume the responsibility that the part will not adversely affect the safe performance of the system. The authority and the manufacturer of the aftermarket part must analyze and certify in writing that use of the part will not result in a failure of the system to comply with safety regulations and safety performance. Completion of such an analysis and certification is considered due diligence and standard practice, will not be reviewed or approved by Alstom, and neither absolves the authority and aftermarket part manufacturer of responsibility nor implies approval by Alstom to use such an aftermarket part. The responsibility of any consequences resulting from using such a part remains with the authority and part manufacturer.

P2521B, Volume 3, Rev. E, Nov/13 1–1 Alstom Signaling Inc.


1.2 MANUAL SET ORGANIZATION

This manual is part of a five volume set supporting the iVPI system. The set is organized as follows:

• Volume 1, Installation, Operation, and Theory Manual, includes a general overview of the field installation and setup of the iVPI system; including capacity guidelines and allowable GTP/NVSP board combinations, system operation, and theory of operation.

• Volume 2, Subrack Configuration, describes the subrack configuration including cables and power supplies.

• Volume 3, Vital Subsystem, is this document. It includes the Vital subsystem board drawings and board reference data.

• Volume 4, Non-Vital Subsystem, includes non-vital subsystem board drawings and board reference data.

• Volume 5, Maintenance and Troubleshooting, describes system maintenance and troubleshooting, including discussion of diagnostics and references for the applicable software and hardware manuals.



1.3 SUBRACK TERMS

The iVPI System is highly modular in design, implemented in a 19-inch rack mounted card cage (Subrack) with a set of plug-in printed circuit boards (boards) that are applied in varying quantities to meet the needs of specific applications.

The terminology used to define the Subrack and its components is as follows:

• A Subrack is a Chassis with Motherboard

• A System is one or more Subracks filled with the appropriate boards for the application

• When a System is configured with more than one Subrack populated with boards, the individual populated Subracks are Subsystems

Figure 1–1. iVPI Rack and Subrack



1.4 VITAL SUBSYSTEM iVPI systems are explicitly designed for operation in the extremely harsh environments seen in railroad and transit properties. The iVPI product line is designed, validated and verified for operation per the AREMA Communication and Signal Manual, Part 11.5.1 for Class C (Wayside Signal Enclosures) and Class D (Wayside Control Rooms) environments without the need for any special environmental conditioning. In practice, each iVPI system for Vital application is comprised of system boards and the appropriate quantity and type of input and output boards required for the particular location. iVPI system board for a typical North American Rail application is:

• Vital System Processor (VSP) board

The iVPI Vital input and output boards are:

• Direct Input (DI) Board

• Single Break Output (SBO) Board

• Double Break Output (DBO) Board

• Lamp Driver Output (LDO) Board

• AC Output (ACO) Board

For typical Freight Rail, Commuter Rail, and Light Rail applications, these boards are also available:

• Code Rate Generator (CRG) board

• Genrakode Track Processor (GTP) board

In addition to the system boards listed above, the Vital system may be configured with one or more optional VSP Interface boards to simplify the physical and electrical connections to the VSP board:

• VSP P2 System ID Board

• VSP/BEX Interface Board

• VSP P3 Interface Board

In addition, the VSP/BEX Interface Board is used in each expansion Chassis configuration. This allows a single VSP board to control both Vital and non-vital boards in up to three external iVPI expansion Chassis.

Figure 1–2 is a block diagram of the boards in the Vital and non-vital subsystems.

1.4.1 VRD Relay

WARNING

iVPI contains special safety circuit components which must only be replaced by components specified by the Alstom part number.

These original-design replacement parts are manufactured to the same standards as the original parts; their performance being verified. The use of replacement parts that are not of the same Alstom part number could potentially impair the safe performance of the system.

The railroad or transit system authority and the manufacturer of an aftermarket (i.e., non-Alstom designated) part assume the responsibility that the part will not adversely affect the safe performance of the system. The authority and the manufacturer of the aftermarket part must analyze and certify in writing that use of the part will not result in a failure of the system to comply with safety regulations and safety performance. Completion of such an analysis and certification is considered due diligence and standard practice, will not be reviewed or approved by Alstom, and neither absolves the authority and aftermarket part manufacturer of responsibility nor implies approval by Alstom to use such an aftermarket part. The responsibility of any consequences resulting from using such a part remains with the authority and part manufacturer.

Every Vital system requires at least one B relay which is operated by the VRD and through whose front contacts all the energy for the Vital outputs is broken. This relay must be, and must only be replaced by, an Alstom VRD Relay, part number 100 ohm B relay 56001-787-05.

A front contact from the VRD Relay must be fed back into the iVPI system as a Vital input for use in the application, for example, to prevent vital timers from starting when the VRD is de-energized. The name of this Vital input may be VRDFRNT-DI.

Note: The front contact used as the Vital input is also available to supply energy to Vital outputs.


VSP Board

SECTION 2 – VSP BOARD

2.1 GENERAL

This section describes the Vital System Processor (VSP) board, P/N 31166-427-XX,

used in the iVPI system. See Figure A–1 for a board layout drawing.

2.2 INTRODUCTION

The VSP board is the Vital processing unit of the iVPI system. It provides Vital logic processing, Vital I/O control and monitoring, on-board programming, and Ethernet communications.

2.3 FUNCTION

The VSP board can process thousands of Vital expressions, read up to 320 Vital inputs

(20 DI boards), set up to 320 Vital outputs (40 Vital output boards, such as SBO, DBO,

LDO, ACO), interface to up to ten GTP boards (20 Genrakode III Track Circuits) and three CRG boards (8 coded outputs per board), process up to 332 Vital timers (32 of which are programmable without recompiling the application program), receive and transmit Vital network data, and receive and transmit non-vital controls and indications, all within iVPI’s fixed Vital 1-second cycle time.

The board includes serial and USB connections for a local maintenance and diagnostics interface, and Ethernet connectivity for a maintenance and diagnostics interface to a remote computer and Vital communications with remote systems.

Through the use of application tools available in the CAAPE program, an engineer defines the logic, I/O functionalities, and communications to implement the interlocking control functions. The Vital application is compiled using the tools and is downloaded directly to the VSP via a serial or USB type connection interface.

Within iVPI’s fixed Vital 1-second cycle time, the VSP:

• Processes up to 4000 Vital expressions

• Reads up to 320 Vital inputs (20 DI boards)

• Sets up to 320 Vital outputs (40 Vital output boards, such as SBO, DBO, LDO,

ACO)

• Interfaces to up to ten GTP boards (20 GENRAKODE III Track Circuits)

• Interfaces to up to three CRG boards (8 coded outputs per board)

• Processes up to 332 Vital timers

• Receives and transmits Vital network data (32 VSOE links, application-dependent)


VSP Board

A diagnostic program is incorporated in the logic processor program memory and tests the different operations from the CPU and peripheral boards. These checks are available through an external monitor (via the on-board serial or USB connection) or

Alstom Maintenance Management System (MMS) (via the Ethernet connections).

Figure 2–1. VSP Board


VSP Board

2.4 INDICATIONS

The VSP board has LED indications that provide a visual indication of the status of the board, the processors, serial channels, and network links. A Health LED is used to indicate board health status. See Figure 2–2 for an illustration of the board edge, including LEDs, ports, push buttons and 7-segment displays.

The behavior of the 7-segment display on the VSP board is as follows:

• 0 = Valid operation, no error

• 1 = Non-fatal error, possibly degraded operation

• 2 = Fatal error, operation degraded or halted

• b = Bootloader Monitor mode active, run-time functionality disabled

• A series of changing signals (different series on different boards and processors) denotes a software download in progress

DI Board

SECTION 3 – DI BOARD

3.1 GENERAL

This section describes the Direct Input (DI) board, P/N 31166-429-XX, used in the iVPI

system. See Figure A–2 for a board layout drawing.

3.2 INTRODUCTION

DI boards are used to vitally input the status of devices such as switch machines, track circuits, line circuits and a multitude of other Vital signal apparatus. The DI boards contain sixteen isolated Vital inputs for DC input current sensing. Each input port has two connections to the field equipment (IN+ and IN–), and two inputs may be connected in parallel with opposite polarity to form a bipolar input circuit. Each input circuit is vitally isolated from each other, from ground, and from power using techniques that meet or exceed AREMA isolation requirements. Using a unique Vital time interval sampling technique, Vital inputs are immune from false readings due to induced AC frequencies in the range of 25 to 360 Hz. Appropriate transient protection devices are included in the input circuit on the PC board.

The DI board:

• Contains sixteen isolated Vital inputs for DC input current sensing, typical input voltage range is between 9–16 VDC

• Includes two connections to the field equipment (IN+ and IN–) for each input

• Allows two inputs to be connected in parallel with opposite polarity to form a bipolar input circuit

• Has vitally isolated input circuits, isolated from ground and from power using techniques that meet AREMA isolation requirements (2000 VDC)

• Includes induced AC frequencies in the range of 25–360 Hz to provide immunity from false readings

• Contains appropriate transient protection devices in the input circuit on the PC board


DI Board

Figure 3–1. DI Board


DI Board

3.3 OPERATION

Each DI board contains 16 isolated inputs. Each input requires two connections to the field (IN+, IN–). The inputs are DC current sensing and require a minimum of 12.8 mA.

The maximum input current is 33.0 mA. Two inputs may be connected in parallel with opposite polarity (for example, input a+ connected to input b– and input a– connected to input b+) to form a bipolar input.

Each input has an indication that is “ON” when the input is “ON” (for example, current flow from IN+ to IN– terminals). The input circuit indications are placed in sequence from 1 to 16 corresponding to inputs 1 to 16 (counting from the top of the board down).

The board has an activity indication which is “ON” for approximately 50 ms whenever data is written to the board. When the system is operating normally the activity indication flashes once each second. The board also has a health indication. It can be green, red or orange.

3.4 INDICATIONS

The DI board has LED indications that provide a visual indication of the status of the board and inputs. A Health LED is used to indicate board health status. See Figure 3–2 for an illustration of the board edge.

Vital DC Output Boards

SECTION 4 – VITAL DC OUTPUT BOARDS

4.1 GENERAL

This section describes the Vital DC Output boards, P/N 31166-430-XX, -431-XX,

-433-XX, used in the iVPI system. See Figure A–3 through Figure A–5 for board layout

drawings.

4.2 INTRODUCTION

The Vital DC Output boards are used to output to a wide variety of Vital devices such as switch machines, line circuits, signal lamps and a multitude of other Vital signal apparatus. There are three Vital output boards for the iVPI system:

• Single Break Output, SBO (P/N 31166-430-XX)

• Double Break Output, DBO (P/N 31166-433-XX)

• Lamp Drive Outputs, LDO (P/N 31166-431-XX)

All are configured with eight Vital outputs per board. The single break output is analogous to a single relay contact placed in the positive or feed side of the circuit. The equivalent to the relay contact in the solid state circuit is the FET switch. The double break output is analogous to a relay circuit with the contacts in both the feed and return sides of the circuit. With the solid-state equivalent, however, each output is completely isolated from all other outputs and/or power supplies.

4.3 OPERATION

LED indications are on each output board. Each indication lights only when the system requests the associated output to turn on.

Eight outputs on each board are divided into two groups of four. Outputs 1–4 are connected to one power supply input, while outputs 5–8 are connected to a second power supply input. These power supply inputs may be connected to different power supplies or they may be tied together external to the iVPI system.

WARNING

If the outputs are being used in a Vital application, the power supply must come from a source that can be vitally turned off—usually a front contact

(closed when the relay is energized) of the iVPI VRD Vital relay or one of its

repeaters. Refer to Section 1.4.1 for more information.



4.4 INDICATIONS

The output boards have LED indications that provide a visual indication of the status of the board and output status. A Health LED is used to indicate board health status. See

Figure 4–1 through Figure 4–3 for illustrations of the board edges, including LEDs and for the LDO board the push buttons and 7-segment displays.

4.5 SBO DETAILS

SBO boards contain eight vitally isolated outputs per board. Each output has one connection to field equipment (+OUT). The negative side of each group of four outputs is connected to common. This group reference is available at the board connector and each group of four outputs may be connected to a different reference. The output port on a SBO board is analogous to a relay circuit with a contact in the feed side of a circuit only. Supply voltage to the output board can be in the range of 9–30 VDC with loads up to 0.5 amps.

Appropriate points in the Vital output circuit have RF Bypass capacitors to ground to eliminate RF interference. Appropriate transient protection devices are also included in the output circuits on each PC board.

The single break output is analogous to a single relay contact placed in the positive or feed side of the circuit. The equivalent of the relay contact in the solid-state circuit is the

FET switch. Figure 4–5 shows the SBO board block diagram.

WARNING

The SBO board may fail with up to 3 milliamperes of output leakage current with the system requesting the output to be in the de-energized state. To prevent a potential unsafe condition, any load device attached to a low current Vital output circuit board must not operate and must de-activate above 3 milliamperes. This includes all environmental operating conditions and all operating values of the load device over its service life. Failure to follow this requirement may lead to unexpected operation of the load device.



4.6 DBO DETAILS

DBO boards contain eight vitally isolated outputs per board. Each output has two connections to field equipment (+OUT and –OUT) and two outputs may be connected with opposite polarity to form a Bipolar output circuit without requiring a separate external isolator interface for either the Double Break or the Bipolar mode of field connection. The output port on a DBO board is analogous to a relay circuit with contacts in both the feed and return sides of the circuit.

Each output circuit is vitally isolated from each other, from power and from ground.

Supply voltage to the board can be in the range of 10–16 VDC with loads between

250 and 3,000 ohms. Additional board voltages are to be supported as required by specific applications. Being a fully isolated double break output circuit arrangement, this output can tolerate a single point failure to ground or to power without any damage.

Appropriate points in the Vital output circuit have RF bypass capacitors to ground to eliminate RF interference. Appropriate transient protection devices are also included in the output circuits on each PC board.



Figure 4–7. DBO Board



The double break output is analogous to a relay circuit with the contacts in both the feed and return sides of the circuit. With the solid-state equivalent, however, each output is completely isolated from all other outputs and/or power supplies. Each output is isolated. Figure 4–8 shows the DBO board block diagram.

WARNING

The DBO board may fail with up to 3 milliamperes of output leakage current with the system requesting the output to be in the de-energized state. To prevent a potential unsafe condition, any load device attached to a low current Vital output circuit board must not operate and must de-activate above 3 milliamperes. This includes all environmental operating conditions and all operating values of the load device over its service life. Failure to follow this requirement may lead to unexpected operation of the load device.



4.7 LDO DETAILS

LDO boards contain eight Vital outputs per board to directly drive incandescent signal lamps or to directly drive signal lamp LED assemblies. Each output has a Sourcing

Drive (positive side switch) capable of providing a maximum output current of 3.3 amps per port. The supply voltage to the board can be adjusted externally to account for line losses to the bulb/LED signal assembly in order to get the desired voltage at the bulb/LED Signal Assembly (provided the 3.3 amps per port is not exceeded). Each port has over-current protection and over-current detection with an appropriate diagnostic.

The LDO board includes hot and cold filament check for incandescent bulbs and for

Alstom approved LED Signal Assemblies as well as an adjustable low level current detection threshold range for LED signal assemblies. Each group of four output ports shares a common reference signal. The positive side of each output circuit is vitally isolated from each other, from power and as a group of four outputs from ground.

Appropriate points in the Vital output circuit have RF bypass capacitors to ground to eliminate RF interference. Appropriate transient protection devices are included in the output circuits on each PC board.



Figure 4–10. LDO Board



The lamp drive output circuit handles high current to light signal lamps. Each output circuit can accommodate hot and cold filament checks. This output uses an FET switch in the “high side” of the circuit. Therefore, it is necessary to supply the common side of the battery or signal lighting supply to the signal lamps. Figure 4–11 shows the LDO board port interface block diagram.

Figure 4–11. LDO Board Port Interface

The LDO board includes:

• A Diagnostic Interface to iVPI VSP Board that registers all current readings and error conditions and can be read or cleared via the iVPI VSP Board.

• A Board Edge User Interface that registers all current readings and error conditions and can be read or cleared via a Board Edge User interface.

• A Current Monitor (LCTH) that reads the current through the output approximately every 200 milliseconds. This current can be compared to one of eight different threshold levels (0.0, 0.55, 0.75, 0.95, 1.25, 1.55, 2.05, or 3.25 amps) to turn the output off if it is not drawing the minimum required current. The use of the iVPI filament checking routines enables downgrading and prevents upgrading to signals that are not drawing the required current. The outputs are protected from overcurrent and short protection.

• A Cable Integrity Check that uses isolated voltage sensing at the output to determine if a potential exists across the output when the output is off. A separate switch for each output can be used to select the system reaction to this event (log the error or drop the iVPI Vital Relay).



4.7.1 Enable/Disable VRD Drop Switches

This is an eight-position DIP switch, one switch per output. When enabled, a CIC error causes the removal of Vital Power. When disabled, the error is still stored on the board until cleared (see Clear Switch below).

4.7.2 Low Current Threshold Switches

This is a series of 10-position rotary switches, one per output, that allow eight selections for the Low Current Threshold of the Current Monitoring function. One setting disables the Low Current Shutdown and is intended for incandescent bulb signals. Five settings indicate a possible decrease in luminance for LED signals. The 2.05 setting could be used with a 25 W load to indicate a Low Vital Power Indication. The 3.25 A setting may be used in future designs that drive two 25 W loads to indicate “One Filament Out”.

4.7.3 Toggle Switch

This switch enables maintenance personnel to monitor various functions on the LDO board. It is used to select which output to monitor and whether to display Current or

Errors for the particular output.

This switch also controls what is displayed on the 7-segment displays. See Section

4.7.5.2 for more information about the 7-segment displays.

4.7.4 Clear Switch

This switch enables maintenance personnel to clear out the Error Registers, Current

Reading Registers, and resets all board states.

4.7.5.2 7-Segment Displays

The ENT/SEL toggle switch is used in conjunction with the OUT 7-segment display and

DATA 7-segment displays to show the output number (1–8) and the current draw of each output, or to check for errors on the outputs.

• Output Current Draw: Put the ENT/SEL toggle switch UP to cycle through the outputs (1–8) on the OUT 7-segment display and the output current draw (in amps) on the DATA 7-segment displays.

• Output Error Checking: Put the ENT/SEL toggle switch DOWN to check each output for errors. If an error is present, the decimal point lights on the OUT 7segment display and the DATA 7-segment displays show the error code (E1–E4).

If there are no errors, “E –” appears on the DATA displays.

ACO Board

SECTION 5 – ACO BOARD

5.1 GENERAL

The Vital AC Output (ACO) board, P/N 31166-432-XX, operates in a manner similar to

Vital DC output boards. See Figure A–6 for a board layout drawing.

5.2 INTRODUCTION

The ACO board is used for lighting signal lamps or for operating other AC loads. The board has eight outputs divided into two groups of four. Outputs 1–4 are connected to one power supply input while outputs 5–8 are connected to a second power supply input.

WARNING

If the outputs are being used in a Vital application, the power supply must come from a source that can be vitally turned off—usually a front contact

(closed when the relay is energized) of the iVPI VRD Vital relay or one of its repeaters.

Two versions of the ACO board are available:

• P/N 31166-432-01 is capable of driving loads up to 0.8 amps and provides a high output current threshold.

• P/N 31166-432-02 is capable of driving loads up to 0.5 amps and provides a low output current threshold.

CRG Board

SECTION 6 – CRG BOARD

6.1 GENERAL

The Code Rate Generator (CRG) board, P/N 31166-459-XX, is a Vital iVPI board that

generates coded outputs. See Figure A–7 for a board layout drawing.

6.2 INTRODUCTION

The CRG board contains eight vitally isolated outputs per board. The CRG board has its own Vital processor engine for generating and proving the pulsed outputs typically used to generate cab signal outputs. Each output has two connections to field equipment

(+OUT and –OUT). The output port on a CRG board is analogous to a relay circuit with contacts in both the feed and return sides of the circuit.

Each output circuit is vitally isolated from each other, from power and from ground.

Appropriate points in the Vital output circuit have RF bypass capacitors to ground to eliminate RF interference.

6.3 OPERATION

LED indications are on each output board. Each output indication lights at the code rate requested from the system.

Eight outputs on each board are divided into two groups of four. Outputs 1–4 are connected to one power supply input, while outputs 5–8 are connected to a second power supply input. These power supply inputs may be connected to different power supplies or they may be tied together external to the iVPI system.

WARNING

If the outputs are being used in a Vital application, the power supply must come from a source that can be Vitally turned off—usually a front contact

(closed when the relay is energized) of the iVPI VRD Vital relay or one of its repeaters.
