MANUAL SPECIAL NOTATIONS
In the Alstom manuals, there are three methods used to convey special informational notations to the reader. These notations are warnings, cautions, and notes. Both warnings and cautions are readily noticeable by boldface type two lines beneath the caption.
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 an operating or maintenance procedure, practice, condition, or statement, which if not strictly adhered to, could result in damage to or destruction of equipment. A typical caution found in a manual is as follows:
CAUTION
Turn power off before attempting to remove or insert circuit boards into a module. Boards can be damaged if power is not turned off.
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
A capacitor may be mounted on the circuit board with a RTV adhesive.
Use the same color RTV.

General Description
1. SECTION 1 – GENERAL DESCRIPTION
1.1. SCOPE OF MANUAL
The purpose of this manual is to describe the principal features of the Alstom Model 5E,
5F, 5G and 5H Electric Switch Machines and tell how to properly inspect, service and test the switch machine, and identify both recommended spare parts and replacement parts. Spare parts are identified in this manual.
To order a switch machine complete refer to the Alstom Signaling Inc. Product and
Parts Catalog. The illustrated catalog also includes all the parts necessary to complete the total layout.
1.2. SWITCH MACHINE FEATURES
The Alstom Model 5E-5H Electric Switch Machines incorporate all of the features required to meet interlocking practices. They can be used at single switches, doubleslip switches, movable-point frogs, and derails, regardless of variations in switch fitting standards and weights of rail. They are notably suitable for use in subways or on rapid transit properties.
5E, 5F, 5G, and 5H switch machines weigh between 900 and 1100 pounds. Models 5E and 5F are about five feet eight inches long by eight inches high by 38 inches wide.
Models 5G and 5H are one foot longer.
1.2.1. Single Control Versus Dual Control
The 5E and 5G Switch Machines operate by the internal electric motor only; they are single-control machines.
The 5F and 5H Switch Machines are operated by a motor or by a mechanical hand throw lever; they are dual control machines.
P1293, Rev. Oct/12 1–1 Alstom Signaling Inc.
General Description
1.2.2. Controllers
Some applications require that a low voltage (10-24 VDC) control from the relay house switch a biased-neutral controller mounted in the switch machine. A biased-neutral controller is actually a device with heavy-duty contacts that control the high current feed wires to the motor.
The 5G and 5H Switch Machines contain biased-neutral controllers. Machines are available that work on low or high voltage DC (24 VDC or 110VDC). The higher operating voltage allows faster movement and less line loss in the cables. Control circuits to the machine operate on 10 or 24 VDC.
Other applications use heavy-duty control relays in the relay house instead of a biasedneutral controller. The 5E and 5F Switch Machines do not contain biased-neutral controllers; control relays for these switch machines are housed externally. The control circuit uses two biased-neutral control relays.

General Description
1.3.1. Model 5E Switch Machine
The Model 5E Switch Machine is designed for power operation only. A hand crank is provided for making and checking adjustments and for emergency use. The hand crank mechanism has an automatic motor cutout device to prevent power operation with the crank in use.
Control and overload relays are housed externally. The two-wire control circuit uses two biased-neutral control relays and a neutral overload relay. Three wires for motor control are required between the relay housing and the switch machine. The number of indication wires required depends on the type of circuit used.
1.3.2. Model 5F Switch Machine
The Model 5F Switch Machine is the same as the Model 5E machine except that it contains a dual-control mechanism. The Model 5F machine, therefore, is designed for both power and hand-throw operation. A hand crank is provided for making and checking adjustments. The hand crank mechanism has an automatic motor cutout device to prevent power operation with the crank in use.
The gear train is designed in the Model 5F machine to permit removal and replacement of the friction clutch and intermediate gears without disassembling the dual-control mechanism.
1.3.3. Model 5G Switch Machine
The Model 5G Switch Machine is designed for power operation only. A hand crank is provided for making and checking adjustments and for emergency use. The hand crank mechanism has an automatic motor cutout device to prevent power operation with the crank in use.
This switch machine contains a biased-neutral controller. Control energy (10 to 12 or 24 to 32 volts DC) is applied to the controller either through relays located near the switch machine, or directly through the switch control lever. The controller also provides overload protection and dynamic snubbing of the switch machine motor.
1.3.4. Model 5H Switch Machine
The Model 5H Switch Machine is the same as the Model 5G machine except that it has a dual-control mechanism added. This machine is designed for both power and handthrow operation. A hand crank is provided for making and checking adjustments. The hand crank mechanism has an automatic motor cutout device to prevent power operation with the crank in use.
The Model 5H Switch Machine gear train is designed to permit removal and replacement of the friction clutch and intermediate gears without disassembling the dual-control mechanism.

General Description
1.4. MODEL 5 SERIES SWITCH MACHINE COMPONENTS
The switch machine has a DC motor at one end to drive the gear train, which moves the throw bar and the lock rod. To ensure the throw bar and lock rod continue to move easily, preventive maintenance includes inspection; always replace any worn parts.
Figure 1–1 shows the components of a Model 5G switch machine.
P1293, Rev. Oct/12
Figure 1–1. Model 5G Switch Machine Components
1–5 Alstom Signaling Inc.
General Description
Operating energy is derived from a central source, fed through external control relays, and applied to the field windings and armature of the motor. After the machine has operated to the called position and locked the switch, a dynamic snub arrangement stops the motor. A ceramic permanent magnetic detent restrains the motor armature after the dynamic snub stops armature rotation at the completion of a stroke or whenever energy is removed from the motor.
Underneath the outer cover is an inner cover over the gear train.
For maintenance purposes or emergency use, a hand crank is inserted through the top cover. Table 1–2 summarizes the major common components provided on all 5 Series
Switch Machines.
P1293, Rev. Oct/12 1–6 Alstom Signaling Inc.
General Description
1.4.1. Switch Machine Serial Numbers
The underside (inside) of the Gear Compartment Cover has a name plate that includes the switch machine part number and serial number. The switch machine serial number is also stamped on the frame, typically near the mounting holes closest to the motor end.
The name plate attached to the top of the motor case specifies the motor part number and motor serial number.
See Figure 1–2 for the locations of the motor and switch machine name plates and the stamped serial numbers.

General Description
1.5. SAFETY PRECAUTIONS FOR MAINTAINERS
WARNING
WHEN USING THE HAND CRANK ON THIS SWITCH MACHINE, KEEP
A FIRM HOLD ONTO THE HAND CRANK. IF THERE IS SPRING IN THE
SWITCH POINTS WHEN THE MACHINE BECOMES UNLOCKED, THE
HAND CRANK WILL ACCELERATE RAPIDLY IN THE DIRECTION IT IS
BEING TURNED. IF NOT CAUTIOUS, INJURY BY THE CRANK’S
SUDDEN MOVEMENT COULD RESULT.
Safe practices and common sense should always be followed when working around any equipment. Remember that good common sense and an understanding of the equipment is essential to any safety policy. The information following describes the health and safety standards for testing, alterations, repairs, improvements or maintenance for all maintenance personnel.
NOTE
Only authorized personnel who have reviewed and understand the information contained in this manual should be working on or around the switch machine. Maintainers should work in pairs at the switch site.
1.5.1. General Recommendations
Maintenance personnel shall comply with all local laws, rules, statues and regulations of governing or regulatory bodies within the geographical area of operations of the property (or Authority). The requirements of these bodies or the user’s safety manual, whichever are more stringent, shall apply. When specific standards and details are not set forth in the manual, job specifications, or in the local laws and regulations referenced, standards published by the Occupational Safety and Health Administration
(OSHA) shall be applied.
P1293, Rev. Oct/12 1–10 Alstom Signaling Inc.
General Description
1.5.2. Proper Attire
1. Wear hard hats at all times.
2. Wear only leather work shoes that are not worn-out and are in good repair.
Sneakers or tennis shoes are unsafe.
3. Wear clothing of proper fit. Loose fitting clothing is a hazard.
4. Avoid wearing belt type key rings, and never carry tools in hip pockets.
1.5.3. Train Control Room (TCR) Work
All personnel working in the TCR areas shall observe the following outlined safety precautions.
1. Assume busses are energized.
2. Use proper size fuse pullers for inserting and replacing cartridge type fuses. Do not substitute hand tools for fuse pullers.
3. Do not use frayed or worn extension cords. All extension lights must have a protective cover over the bulb.
4. Use extension cords of the three-wire type. If a two-pronged adapter is used, it must have a ground wire attached to a known ground.
5. Use proper socket wrenches (AAR type) when working on entrance racks or racks with AAR terminals. Do not use open end or adjustable wrenches.
1.5.4. General Safety on Property
1. Never go out on a track of an operating railroad alone. Flagmen familiar with operating procedures and safety regulations should accompany all field maintenance personnel for maximum safety.
2. Always be alert and watchful as if each man were by himself. Be aware of the area you and others are at all times. Yell or shout a warning if a dangerous situation develops.
P1293, Rev. Oct/12 1–11 Alstom Signaling Inc.
General Description
1.5.5. Safety at Wayside
1. Check for a safe place to go before starting a job and be sure that enough safe places are available for all personnel on the track. Avoid sudden unplanned moves.
2. Never attempt to complete a job when a train is approaching.
3. When standing along the track in clearance, stand where the train operator can see you and take precautionary measures.
4. When crossing the tracks in front of or behind a stopped train, cross at a great enough distance from the train to be prepared for the train to proceed in either direction.
5. If boarding or dismounting a train, wait until the train comes to a full stop and operator gives permission. When carrying equipment or plans, always hand them up or down to allow free use of your hands.
6. Never step or walk on rails. Slipping off may result in serious injury.
7. Never lay tools or equipment on the rails. Objects left on a rail may derail or damage a train and flying debris could endanger personnel along the track.
8. When taking shelter from an approaching train, always watch for a train on the adjacent track.
9. Exercise special caution in tunnels, curves, turnouts and on grades, as it is very difficult to determine the direction from which a train is approaching and how close is it.
1.5.6. Safety at Station Platforms
1. Jumping up or down between the station platform and track level is dangerous.
When working on tracks or equipment in platform areas, always move into and out of the area at track level.
2. Before stepping out into the track area from a track level TCR, ensure that no train is passing. If a train is standing at the platform, wait until it has passed before exiting.
3. Before ascending steps from track level area to a station platform, ensure that no train is entering or standing at the platform.
4. Before stepping off a platform onto a stairway to the track level, be sure no train is entering or is at a platform behind you.
P1293, Rev. Oct/12 1–12 Alstom Signaling Inc.
General Description
1.5.7. Safety at Switch Machines
1. Keep fingers, feet, tools and equipment out of switch points. Closing points can trap and crush hands and feet or damage tools and equipment. A wedge properly inserted between points will prevent an inadvertently energized switch machine from causing personal injury or equipment damage.
WARNING
ALWAYS BE PREPARED FOR IMMEDIATE SWITCH MOVEMENT.
FAILURE TO DO SO COULD CAUSE YOU TO BE INJURED BY
UNEXPECTED OPERATION.
3. Never step on switch rods. Rod movement can cause serious foot injury or loss of balance.
4. Because the switch machine is often activated from a remote station (a train control room), be sure to notify this station that maintainers are working on or around a given switch machine. This notification may prevent the equipment from being activated during the reported service.
When the hand crank is inserted, the motor is electrically cut off and the machine can not be activated. Insert a hardwood wedge into an open switch point (the gap that is formed between the through and alternate track) to prevent the point from closing. Use these features as protection, but never leave a hand crank inserted in a switch machine or wedge in the switch points when a train is approaching and the switch must be thrown.

Theory of Operation
2. SECTION 2 – THEORY OF OPERATION
2.1. GENERAL
This section discusses the basic operation of the 5E, 5F, 5G, and 5H Switch Machines and highlights the main differences between the four versions. Table 1–1 compares and summarizes the principle features of each switch machine.
2.2. POWER OPERATION
A switch machine is an electro-mechanical device consisting of a motor and gear train which moves the rails (points) into position for a rail vehicle to change route.
The motor uses a clutch and gear mechanism to move the throw bar. The throw rod connected to the throw bar moves the switch points. Depending on the direction of rotation of the switch machine motor, either the near or far switch points close.
The lock rod is connected to the switch points by the lock connecting rod. The lock rod mechanically locks the switch points against any movement away from the position of correspondence, which is defined as the point where the position indicated by the switch call circuitry “corresponds” with the indications provided by the point detector circuits. The switch machine remains in the locked position until the machine receives a signal to reverse the action.
The point detector rod is connected to movable switch points by the point detector connecting rod. The point detector rod operates the detector as the switch points move, providing the associated circuits of the display panel and signal control relays with the switch point position indications. Figure 2–1 shows the cam bar and point detector rod along with the detector yoke. Figure 2–2 shows each of the four operating positions.
The point detector motor control contacts remove energy from the motor after each stroke.

2.5.1. Motor
The 24- or 110-volt motor is fastened to the end of the machine frame with four fasteners that can be easily removed.
The magnetic detent is a permanent magnet holding device mounted on the outer motor frame. It includes a front bearing for the motor armature, thus making the motor a complete unit. Figure 2–8 shows the motor and its detent.
Figure 2–8. DC Motor
In Models 5E and 5F, the circuit includes the snub-resistor lead, one-half of the snub rectifier, point-detector contacts, and the opposite field coils of the motor. In the Models

P1293, Rev. Oct/12 2–9 Alstom Signaling Inc.
Theory of Operation
The switch machine motor converts 110 VDC (or 24 VDC) electrical energy to mechanical energy, providing a rotating motion for driving the gear train. Reversing current flow to the motor and energizing different field coils changes direction of rotation. Figure 2–9 shows the motor connection diagram as viewed from the commutator end of the motor.
Figure 2–9. Motor Connection (Series Split Field) Diagram
Electrical motors are furnished with series split-connected field coils. The internal arrangement of the field coils does not permit changes in the field coil connections.
Each field coil is stamped with Alstom drawing number and resistance value.
Resistance of 110-volt coil is 0.354-ohm; resistance of 24-volt coil is 0.105-ohm.
When viewing the motor from the commutator end, the armature rotates to the right when positive energy is supplied to Terminal 6 and negative energy to Terminal 4.
Positive flow is through the armature to Terminal 1, through field coils F3 to F4 and then to Terminal 4. Viewed from the commutator end, the armature rotates to the left when positive energy is supplied to Terminal 3 and negative energy to Terminal 6. Positive flow is through field coils F1 and F2 to Terminal 1, through the armature and then to
Terminal 6.
NOTE
Field coils F1 and F2 are energized for rotation to the left and coils F3 and
F4 are energized for rotation to the right.
P1293, Rev. Oct/12 2–10 Alstom Signaling Inc.
Theory of Operation
2.5.1.1. Commutator and Brushes
The commutator is part of the armature to which the windings are connected. The commutator consists of an insulated steel hub with wedge shaped insulated copper segments arranged around the hub.
Brushes made from current conducting material ride on the commutator, making an electrical connection between the commutator and the power supply. Brushes ride on the outer edges of commutator bars that are connected to armature windings, and are seated to match the shape of the commutator. To insure proper electrical contact, brush pressure to the commutator is set to 1-1/4 to 1-3/4 pounds.
The commutator and brushes work together to provide current to the correct armature winding(s) to generate torque as shown in Figure 2–10.
Figure 2–10. Commutator and Brushes
A heater is located over the commutator and brushes to eliminate moisture in the motor area. The heater is energized by a 110 VAC source.
P1293, Rev. Oct/12 2–11 Alstom Signaling Inc.
Theory of Operation
2.5.1.2. Magnetic Detent
At the completion of each stroke, the overrun of the motor generates a current. This current flows through a low-resistance circuit. Flux generated in this circuit quickly slows and stops armature rotation.
• In Models 5E and 5F, the circuit includes the snub-resistor lead, one-half of the snub rectifier, point-detector contacts, and the opposite field coils of the motor.
• In the Models 5G and 5H, the circuit includes the snub-resistor lead, one-half of the snub rectifier, the snub contact in the controller, and the opposite field coils of the motor.
The holding device magnetically locks the motor armature when it is not rotating. A permanent ring magnet is fixed to the housing cover while a similar magnet is attached to the armature shaft. These magnets, shown in Figure 2–11, slow the motor to prevent unwanted armature rotation after energy is removed from the motor.
With the motor de- energized, the poles of the armature magnet line up with the poles of opposite polarity in the fixed magnet. A magnetic detent effect, produced by a magnetic-flux linkage between the magnetic poles, prevents armature rotation.
P1293, Rev. Oct/12
Figure 2–11. Schematic Diagram of Holding Device,
Showing Magnetic Detent Effect
2–12 Alstom Signaling Inc.
Theory of Operation
When the motor is energized, the motor torque overcomes the magnetic restraining force, and the armature magnet rotates parallel to the fixed magnet. At the completion of the switch stroke, the dynamic snub on the motor again stops the armature rotation, and the holding device securely prevents any more armature rotation.
It is necessary to overcome the initial holding force of the holding device when hand cranking the machine, but once started, cranking is easy to do. The full restraining effect returns any time cranking slows down enough or stops permitting the magneticflux linkage to overcome the cranking torque.

2.5.2. Hand Crank Cutout Switches
The cutout switch, shown in the open position in Figures 2–12 and 2–13, removes all power to the switch machine motor. The cutout switch is engaged via the mechanical interaction of the hand crank being inserted into the blocking plate. To insert the hand crank, the hole in the blocking plate must align with the hole in the clutch pinion. When the blocking plate moves, the contact plunger also moves and opens the control line to the motor armature.

2.5.3. Friction Clutch
The friction clutch shown in Figure 2–14 reduces gear mechanism shock and motor burnout. The friction clutch is typically adjusted to slip when motor operating current exceeds 12 to14 amps for 110V switch machines or 17 to 20 amps for 24V switch machines. The overload relay, located in the control circuit, opens the switch motor control circuit approximately 3 seconds after the clutch begins slipping. To reset an overload condition, the switch must be called to the opposite position.
The pinion gear of the motor meshing with the bevel gear drives the clutch body. Inside are friction disks compressed against the clutch body. Some disks are engaged with the pinion shaft. Other disks (metal) are engaged with the clutch body. The pinion is driven until torque to drive the remainder of the gear train increases enough to cause the friction disks to slip. When the friction disks slip, the clutch body continues to rotate though the pinion stops.
WARNING
FRICTION DISCS IN OLDER CLUTCHES MAY CONTAIN ASBESTOS.
FOLLOW PROPER ASBESTOS HANDING PROCEDURES
ACCORDING TO LOCAL REGULATIONS.
THE ASBESTOS CONTAMINATION MAY EXTEND TO NEARBY
SURFACES AND GREASE.
An adjusting nut is provided to increase or decrease the amount of pressure on the friction disks to the clutch body. The maximum amount of torque that the friction clutch pinion must provide for the switch machine to move the switch points and provide for switch point pressure is closely related to current draw of the motor.

2.5.4. Cam Bar, Throw Bar, Point Detector Mechanism
The cam bar, throw bar and point detector mechanism work together to provide the actual movement of the switch points. The locking of the switch points in the near and far positions, and indication of switch point positioning is obtained by the mechanical operation of the point detector.
A roller drives the cam bar. Movement is along the length of the machine frame. First movement of the cam bar causes the point detector to swing to the center position by the point detector dog on the cam bar, intercepting lower rollers on point detector yoke.
See Figure 2–16.
Figure 2–16. Cam Bar Centering Point Detector
With continuing motion of the cam bar, the lock rod dog on the cam bar, unlocks the lock rod by withdrawing from the notch in the lock rod, as shown in Figure 2–17.
Figure 2–17. Lock Rod in Locked and Unlocked Positions
P1293, Rev. Oct/12 2–19 Alstom Signaling Inc.
Theory of Operation
Final cam bar motion towards the point detector unlocks the throw bar. The throw bar dog on the cam bar withdraws from the throw bar locking surface, as in Figure 2–18.
Figure 2–18. Throw Bar Dog Unlocking Throw Bar
After the cam bar moves completely to the unlocked position, the cam roller drives the throw bar and switch points to the opposite position, as in Figure 2–19.
P1293, Rev. Oct/12
Figure 2–19. Cam Roller Moving Throw Bar
2–20 Alstom Signaling Inc.
Theory of Operation
Following movement of the throw bar to the opposite position, the cam roller continues moving and pulls the cam bar back toward the motor end of the machine. The throw bar dog on the cam bar slides against the locking surface of the throw bar, thus locking the throw bar in the opposite direction. The lock rod dog positions itself into the slot in the lock rod, locking the lock rod in place.
Final movement of the cam roller and cam bar releases the point detector yoke by the point detector dog moving away from the lower rollers on the point detector yoke. The point detector yoke is then allowed to swing into a new position depending on the positioning of the point detector rod and the lock rod.

2.5.5. Lock Rod
The Lock Rod, when released by the cam bar lock dog, follows the movement of the switch points and locks the switch points in the near of far positions. Two lock rod arms

P1293, Rev. Oct/12 2–22 Alstom Signaling Inc.
Theory of Operation
The two lock rod arms ensure that false point detection is not obtained when the switch machine is locked if the lock and detector rods have not moved together. This provides protection against a broken or loose point-detector connection or a broken or loose lock rod. This protection is obtained by the interference between the end of the contact yoke and a blocking arm as shown in Figure 2–22. This view shows the point-detector contact yoke from the motor end of the switch machine.

Theory of Operation
2.5.6. Point Detector Rods
The point detector rod follows the position of the switch points. When released, the point detector yoke drops into the grooves cut in the top of the rod, showing the point position. Figure 2–23 illustrates the point detector rod in extreme positions and the point detector yoke engaged to the rod grooves.
If the point detector rod moves far enough from the extreme positions, the point detector yoke swings to a center position, such as when a switch is improperly trailed.
Locating notches are provided on the rods to allow initial adjustment of the rods to the switch layout.
Figure 2–23. Point Detector Rod Normal and Reverse Positions
The point detector rod is connected to movable switch points by the point detector connecting rod as shown in Figure 2–24. The point detector rod operates the detector as the switch points move. The point detector contacts remove energy from the motor after each stroke and provide the associated circuits of the display panel and signal control relays with the switch point position indications.

2.5.8. Point Detector Circuit Controller
The switch machine includes a point detector circuit using point detector contacts and point detector rods.
The point detector circuit controller is an over-and-lock type of circuit controller. Some point detector contacts indicate and verify that switch points are within the proper distance of the stock rail. These contacts then verify that the points are locked at the end of the point movement. Other contacts control the motor operating circuit. When the point detector is not in a closed position, contacts shunt the indication circuit to prevent false indications due to grounding or induced currents. Figure 2–27 shows a top view of circuit controller contacts. See Figure 2–22 for examples of engaged contacts.

2.5.8.2. Motor Control Contacts
During motor operation, both motor control contacts are closed due to detector yoke pivoting to center position. Only one of the two motor control contacts provides energy to the electrical circuit for the motor winding. At completion of movement, the detector yoke pivots, as shown in Figure 2–29, opening only that motor control contact providing energy to the electrical circuit, thereby de-energizing motor. The other motor control contact, still closed, is part of motor snub circuit and is in position to apply energy to switch the motor for next switch movement.

2.5.8.3. Shunt Contact
Immediately after the snub and normal/reverse contacts are opened, shunt contacts, shown in Figure 2–30 and 2–31, are closed. If the machine is unlocked, or if the point detector rod is out of adjustment, a shunt is placed on the repeater relay circuit. The shunt prevents the energizing of the repeater relays so that any outside energy present does not give a false indication when the machine is not over and locked.

2.5.9. Switch Machine Wiring
A built-in biased-neutral controller with dynamic snubbing is furnished in Model 5G and
5H switch machines. This controller provides for two-wire polarized control, either normally energized or de-energized. Overload protection is self-contained. The snub arrangement provides for dynamically snubbing the switch machine motor after it has operated and locked the switch.
CAUTION
To preserve the dynamic snubbing feature, limit the number of consecutive throws to ten (10), followed by a 60 second wait to allow cool down of the snub resistor wire before actuating an additional series of throws.

Theory of Operation
When the switch machine is to operate to the left, positive control energy is applied to the NWR wire and negative control energy to the WR wire. This causes contactor C2 to be energized. When contactor C2 picks up, the snub contact opens. Contactor C2 closes its front contact and, through the centering device, closes the back contact of contactor C1. This completes the motor circuit, and operating energy flows from terminal 5, through the front contact of C2, the reverse field of the motor, the armature, the crank contact, the operating coil of the overload relay, and the back contact of contactor C1 to negative.
As the switch machine unlocks, point-detector contacts 7D-2C close. The machine continues to operate to the left. When the machine completes its stroke, point-detector contacts 1C-8D open, de-energizing contactor C2 and opening the motor circuit. The contactor armatures return to their normally centered position and the snub contact closes. The motor armature continues to rotate, generating a dynamic current that flows from field coil through terminals 4 and 9, one-half of the snub rectifier, the snub resistor lead, the snub contact, terminals 12 and 7, the crank contact, terminal 6, the armature, terminal 1, and back to coil N.
When the switch machine is to operate to the right, positive control energy is applied to the WR wire and negative control energy to the NWR wire. This causes contactor C1 to be energized. When contactor C1 picks up, the snub contact opens. Contactor C1 closes its front contact and through the centering device closes the back contact of contactor C2 (point-detector contacts 7D-2C were closed and contacts 1C-8D were opened during the operation of the machine to the left). This completes the motor circuit, and operating energy flows through the motor in a direction to operate the machine to the right.
As the machine completes its stroke, contacts 7D-2C open, de-energizing contactor C1 and opening the motor circuit. The contactor armatures return to their normally centered position and the snub contact closes. Any overrun of the motor armature generates a dynamic current that now flows from field coil through terminal 1, the armature, the crank contact, terminals 7 and 12, the snub contact, the snub resistor lead, the other half of the snub rectifier, terminals 8 and 3, and back to coil R.

The Overload Relay, Figure 2–36, operates to release the energized contactor, which in turn opens the motor circuit whenever an overload is encountered. The operating coil is connected in multiple with external resistance wire RT. Normally, most of the operating current flows through the resistance wire and therefore, there is not sufficient current flowing in the operating coil to operate the relay.
High current, such as the motor would draw if there were an overload, heats resistance wire RT and increases its resistance. This effect causes sufficient current to flow through operating coil 0 to operate the relay. Once operated, the armature is held up by a stick coil until the control circuit is either interrupted or reversed.
A metal slug and washers slow operation of the relay so that it does not operate in response to the momentary surges of current that occur when starting or reversing the motor. When the overload relay operates, it removes energy from contactors C1 and C2.

3. SECTION – INSTALLATION
3.1. GENERAL
Model 5E-5H Switch Machines should be installed in accordance with the property’s approved switch layout. A newly installed machine should be adjusted and lubricated according to the criteria in this manual.
Satisfactory operation of the switch machine depends on it being installed properly, adjustments made correctly, all identified parts lubricated according to the lubrication chart, and maintenance performed at regular intervals. Maintain good drainage around a switch machine so it does not flood.
NOTE
After the installation is completed or after making any adjustments to the machine or switch layout, hand crank the machine first before applying
DC power to check for responses to the adjustments.
3.2. PROPERTY’S REQUIREMENTS
Although this publication gives set-up information on a typical machine installation, the maintainer should always be sure the switch layout is done in accordance with the requirements of the rail property.
3.3. INSTALLATION
The installation process consists of three elements: physical mounting of the equipment by the tracks, making necessary adjustments and electrical connections, and testing for proper mechanical movement. Details of this process are described next.
When following the procedures in this manual, the following warnings must be heeded:
WARNING
WHEN USING THE HAND CRANK ON THIS SWITCH MACHINE, KEEP
A FIRM HOLD ONTO THE HAND CRANK. IF THERE IS SPRING IN THE
SWITCH POINTS WHEN THE MACHINE BECOMES UNLOCKED, THE
HAND CRANK WILL ACCELERATE RAPIDLY IN THE DIRECTION IT IS
BEING TURNED. IF NOT CAUTIOUS, INJURY BY THE CRANK’S
SUDDEN MOVEMENT COULD RESULT.
P1293, Rev. Oct/12 3–1 Alstom Signaling Inc.
Installation
WARNING
DISCONNECT MOTOR ENERGY WHENEVER WORKING ON THE
SWITCH LAYOUT OR SWITCH MACHINE. UNEXPECTED OPERATION
OF THE MACHINE COULD CAUSE INJURY FROM OPEN GEAR,
ELECTRICAL SHOCK, OR MOVING SWITCH POINTS.
Keep the clearance between the number one rod and the base of the stock rail 1/4 inch maximum (less is desirable) to prevent the switch points from moving up relative to the stock rail. It is essential if the stock rail is beveled for AREA detail 6100 (Samson) points. During use these points pry themselves away from the stock rail when moving up. This motion may cause the point-detector rod in the switch machine to move enough to open the indication contacts. The tendency of the points to move up and in can also be reduced by keeping the ballast firmly tamped under the ties of the switch layout.
The stock rail and the switch machine must be secured to ties that are well tamped to prevent movement when the switch machine is operated against an obstruction. More than 3800 pounds can be exerted on the number one rod by the switch machine if the clutch is adjusted too tightly.
Gauge plates, extension gauge plates, rail braces, and ties must be correct. Points must fit snugly and uniformly against the stock rails without being bent by force from the throw bar. Excessive throw bar force disturbs the layout and causes excessive wear to the switch machine.
P1293, Rev. Oct/12 3–2 Alstom Signaling Inc.
Installation
3.3.1. Left-Hand or Right-Hand Layout
Different arrangements of single and dual control machines exist, depending on whether left-hand or right-hand switch machine operation is required. A typical layout of the switch machine is shown in Figure 3–1.
Models 5E and 5G Switch Machines with one lock rod and one point-detector rod are supplied for right-hand operation only. They are easily changed to left-hand operation.
Also Models 5E and 5G Switch Machines with two lock rods and two point-detector rods can be ordered for either right-hand or left-hand operation. Machines used for double slip switches can be changed in the field; however, machines for movable point frog applications require different point-detector rods from those used in the existing location, if changing from right-hand to left-hand, or vice versa.
Dual-control Models 5F and 5H Switch Machines can be ordered for either right-hand or left-hand operation. Changing from right-hand to left-hand, or vice versa is not recommended only because much more time is required to convert a dual-control machine than to convert a single-control machine.
Instructions to change switch machine models from left-hand to right-hand layout, or vice versa, are found under heading 3.6. CHANGING FROM LEFT-HAND TO RIGHT-
HAND OPERATION AND VICE VERSA.
An optional Switch Machine and Layout Sensing Kit is available from Alstom (P/N
59649-218-00) that can be used to detect point pressure at each point. For a procedure on use of this kit, see Table 3–15 for the Throw Rod Point Pressure Verification
Procedure.

Installation
3.3.2. Mounting to Ties
All ties that support the switch machine and switch points must be well tamped for their entire length to minimize vibration from passing trains. The two extended ties which directly support the switch machine must be reasonably straight and, where required, properly framed. It is necessary to securely fasten the machine to the ties to ensure little chance of movement with respect to the rails. Also, it is important to check the switch layout plans to verify the installation is correctly made.
3.3.3. Wiring of Machine
In Models 5E and 5F Switch Machines operating circuits are completely wired at the factory. To wire the point-detector, connect the external wires to the machine through a wire entrance fitting to the terminal posts in the machine in accordance with the detail wiring plan that applies to the location.
In Models 5G and 5H Switch Machines, the biased-neutral controller, motor, and pointdetector are completely wired at the factory. In the field, the external wires for switch control, motor energy, heaters (if included), and repeater relay circuits are brought into the machine through a suitable wire entrance fitting and connected to the terminal board posts. To connect these external wires, follow the detail wiring plan for the location.
Typical switch machine wiring diagrams and repeater relay circuits are included in the appendix, and are grouped by model. Repeater relay circuits show metal connectors between some adjacent posts on the terminal board. Connectors are supplied with each new machine and must be arranged as required in the field.

3.3.5. Hand-Throw Lever (Models 5F and 5H Only)
Check that the locations of the letters N and R on the hand-throw lever correspond to the positions of the switch after the machine has been operated by hand.
3.3.6. Hand Cranking Before Applying Power
Once the installation is completed, the hand crank should be used to move the machine to the extremes of the normal and reverse throw positions. Doing this enables the maintainer or installer to check that the adjustments were made correctly and that no undue strain is placed on the layout or parts of the machine. Storage of the hand crank is normally in the toolbox compartment by the motor.

Installation
3.4. LOCK AND POINT-DETECTOR RODS ADJUSTMENT
After the initial switch machine installation is complete, several methods of making adjustments to the lock rod and point-detector rod can be followed. The particular method to be followed depends on the type of lock rod used with a given machine, condition of switch layout and customer standards and requirements. Lock rods are referred to here as narrow or wide-notched. A narrow-notched rod has 2-1/8 inch wide slots; a wide-notched lock rod has 2-5/16 inch slots.

P1293, Rev. Oct/12 3–21 Alstom Signaling Inc.
Installation
3.5.3. Temperature Considerations and Commutator Cover
The silicone-treated, moisture-repellent commutator cover keeps moisture off the commutator. At switch locations where no frost occurs, no cover is needed.
At locations where frost occurs, the cover is used only during the frost season and removed when all danger of frost is past. Replace cover at start of next frost season.
If the used cover is still in good condition, clean it thoroughly with a suitable brush or air blast after removal. The frost shield is then clean and ready for reuse at the start of the next frost season. If the used frost shield is not in good condition, discard it. Put a new one around the commutator at start of the next frost season.
3.5.4. Commutator Shield Use
The transparent commutator shield is furnished only in machines without a 15-watt heater in the motor compartment. It is best to keep shield in place all year and keep nuts tight that hold shield in place. To remove shield, loosen nuts and slide shield toward armature.

4.6. PREVENTIVE MAINTENANCE CHECKS
Preventive maintenance checks should be done to each switch machine, regardless of whether a switch machine operates independently or in series with another switch machine. Preventive maintenance checks are intended to serve as a reference for fault isolation procedures. If a problem is found, take the necessary action to correct it.
When performing the procedures provided in this section, the following warnings must be heeded:
WARNING
KEEP CLEAR OF GEARS AND SWITCH POINTS WHEN INSERTING
OR REMOVING A HAND CRANK. ACTIVATION OF THE SWITCH
MACHINE WHILE INSERTING OR REMOVING THE HAND CRANK MAY
CAUSE EQUIPMENT DAMAGE OR PERSONNEL INJURY. THE
SWITCH MACHINE MAY NOT BE IN ITS FULLY LOCKED POSITION.
THE SWITCH MACHINE CAN BE REMOTELY ACTIVATED WHEN THE
HAND CRANK IS NOT INSERTED. IT CAN BE ACTIVATED ONCE THE
HAND CRANK IS REMOVED AND THE HAND CRANK MECHANISM
CUTOUT SWITCH IS RESET BY MOVING THE BLOCKING PLATE TO
THE NORMAL POSITION.
WARNING
WHEN USING THE HAND CRANK ON THIS SWITCH MACHINE, KEEP
A FIRM HOLD ONTO THE HAND CRANK. IF THERE IS SPRING IN THE
SWITCH POINTS WHEN THE MACHINE BECOMES UNLOCKED, THE
HAND CRANK WILL ACCELERATE RAPIDLY IN THE DIRECTION IT IS
BEING TURNED. IF NOT CAUTIOUS, INJURY BY THE CRANK’S
SUDDEN MOVEMENT COULD RESULT.
Whenever a switch machine is repaired or rebuilt, complete cleaning and lubrication should be performed. These procedures are found in Section 6, Corrective
Maintenance.
4.6.1. After Flooding
If the switch machine is or was flooded, clean, dry and regrease it and make sure that magnetic detent is free of water. In cold weather, trapped water freezes and prevents the switch machine from operating. In this case the sealed motor bearings may require replacement.
After flooding, water-resistant grease in motor bearings may have become contaminated or washed away. If so, the motor should be disassembled and the bearings removed, then cleaned and greased or replaced. This is also true for the main-gear bearings in Models 5F and 5H switch machines. Replace lubricant between the main crankshaft and the clutch sleeve and the clutch gear area.

4.8. MONTHLY MAINTENANCE
4.8.1. Lubrication
Switch machines, located in a clean environment and making an average of less than
20 moves each day, should be lubricated at least once every three months, or when a machine has been flooded. If a switch machine makes more than 20 moves a day or is located in a dusty environment, lubricate machine monthly. An established lubrication routine is recommended for each switch machine based on its use and operating conditions.
CAUTION
Oil or grease in the friction clutch render s the clutch and switch machine inoperable.
Use an all-temperature, lithium-based, extreme-pressure grease, such as Fiske Bros.
Lubriplate MAG 1 per Alstom 91A0012, in all pressure grease fittings, on all gear teeth, on all sliding surfaces, on all surfaces not plated, painted, made of corrosion-resistant material, or coated with anti-rust film, and other parts specified in the tables.
Avoid the use of too much grease and oil; any excess should be removed. By not permitting grease and oil to drop or collect on wires, coils, commutator shield, commutator cover, or friction faces of clutch, a minimum amount of unscheduled maintenance can be expected.
4.8.1.1. Lubrication Procedures
Table 4–3 provides the lubrication procedure. Since the actual lubrication points are slightly different for the single versus dual control machines, Table 4–4 contains the lubrication details for Models 5E and 5G, while Table 4–5 contains the lubrication details for Models 5F and 5H. In addition, Table 4–6 provides the procedure for lubrication through an additional three tubes located on Models 5F and 5H.

Using a force gauge, for example, made by John Chatillon and Sons, pull outward on the twine as nearly horizontally as possible to open the contact.
Contact pressure for shunt contacts in Models 5E and 5F, measured very near point of contact, should be 2-1/2 to 3 pounds, and is adjustable.
Pressure of these adjustable contacts against it stop may be reduced to 3/4 to 1-1/4 pounds when heaters are used in machines.
Coil spring and contact openings determine contact pressure of motorcontrol and shunt contacts of Models 5G and 5H. Pressure is not adjustable for these contacts.
To decrease pressure of a normal, reverse, snub, or Models 5E and 5F shunt contact, bend U-shaped spring in until it has taken a set that gives the desired pressure. To increase pressure, release U-shaped spring from its stop and bend spring outward.

4.9.9. Shunt Contact Check and Adjustment
4.9.9.1. Models 5E and 5F Shunt Contacts C6, C7, D2 and D3
The switch machine shipped from Alstom has shunt strips A, Figure 4–3 connected across contacts C6-D3 and C7-D2. Shunt strips A are used only in a polarized repeater relay circuit. To use a neutral repeater relay circuit, shunt strip A must be removed and shunt strip B must be added between contacts C6-C7 and D2-D3, Figure 4–4 Shunt strips B, supplied with each new machine, are in a bag which also contains the motor ventilators.
When the switch machine operates, the first or unlocking movement of the locking bar simultaneously opens the snub contacts and either the normal or reverse contacts, depending on the direction of operation.
Immediately after these contacts are opened, the shunt contacts are closed. With the machine unlocked, or if the point-detector rod is out of adjustment, there is a shunt on the repeater relay circuit. The shunt prevents pickup of the repeater relays so that any extraneous energy, which may be present, cannot cause a false indication.
In a polarized repeater relay circuit using shunt strips A, Figure 4–3 the shunt is closed through terminal post C6, U-shaped spring (1), front stop (2), shunt strip (A), front stop
(3), U-shaped spring (4), and opposite terminal post D3. A similar shunt arrangement exists between posts C7 and D2.
Figure 4–3. Shunt Contacts Used in Polarized Repeater Relay Circuit
In a neutral repeater relay circuit using shunt strips B, Figure 4–4 the shunt is closed through terminal post C6, U-shaped spring (1), front stop (2), shunt strip (B), front stop
(3), U-shaped spring (4), and adjacent terminal post C7. A similar shunt arrangement exists between posts D2 and D3.
P1293, Rev. Oct/12 4–32 Alstom Signaling Inc.

After the switch points have been properly positioned, the locking movement of the locking bar permits the point-detector to complete its movement. Shunt contact finger
(5), Figure 4–3, which is attached to the movable block, moves U- shaped spring (1) about 1/16 inch before the other section of this contact finger closes the normal or reverse contact. Thus, the shunt on the repeater relay circuit is removed before the normal or reverse contacts and the snub contacts are closed.
In summary, the normal or reverse and snub contacts must be open before the shunt contacts close. Shunt contacts must be open about 1/16 inch before normal or reverse and snub contacts close.

4.9.11. Controller Contact Adjustments
Controllers are components of the Model 5G and 5H Switch Machines only.
Shims are provided behind the upper bearing support of the contactor centering shaft.
These shims permit the centering device to be properly positioned so that the back contact of one contactor makes at the same time, or slightly before, the front contact of the other contactor.
Permanent magnets blowout the arc which occurs during switch operation. These magnets are located behind the snub and contactor contacts. One pole of each magnet is stamped N to indicate which is the north pole of each magnet. If these magnets should be removed, be sure to reassemble them in their original positions with respect to magnet polarity.
When periodic inspection shows there is not enough contact wipe because of wear on the contacts, the contacts should be replaced and adjusted. New contact fingers are not adjusted.

Notice sequence of discs in clutch while removing discs.
Examine friction discs for cracks, roughness or uneven wear.
Examine metal discs for corrosion, roughness or excessive wear. Replace any defective discs. New discs do not contain asbestos.
NOTE
Corrosion is a potential problem because metal discs are hard chrome plated to increase resistance to wear; however, they are susceptible to corrosion. Chrome may peel in a clutch disc, increasing resistance to slippage.
Inspect all friction surfaces of clutch body. If roughness of surfaces noted, repair or replace clutch body.
To reassemble clutch, clean pieces of clutch with soft cloth or bristle brush.
Make sure no grease is present which does not belong.
Apply Rust-Veto™ to unpainted surfaces that do not slide or rotate against anything else.

Troubleshooting
5. SECTION 5 – TROUBLESHOOTING
5.1. GENERAL PHILOSOPHY
Troubleshooting Model 5E through 5H Switch Machines is usually done in the control location before going out to the field for inspection. In order to understand troubleshooting procedures, knowledge of how to read circuit plans is essential. Relays in the control location are checked using a volt-ohm-meter (multimeter). Also, in troubleshooting techniques, a multimeter is used to check continuity of fuses and the resistance of resistors and continuity of circuits.
5.2. POSSIBLE SYMPTOMS AND CORRECTIVE ACTIONS
Tables 5–1 and 5–2 give examples of symptoms of abnormal operation of the switch machine circuit and trackside equipment and how to begin to determine the faulty component or circuit.
A optional Switch Machine and Layout Sensing Kit is available from Alstom (P/N 59649-

Main Gear Assembly For Models 5F and 5H
If the main gear and operating crank are removed and replaced according by following actions a through h listed in Step 23, it should not be necessary to retime the dual control mechanism. Proceed as follows: a. Replace main gear and crank in frame. Be sure to insert crank in same alignment with respect to gear frame as it was before removal. This ensures that the same splines of crank and clutch sleeve are engaged with one another. b. With crank in place, and washers and nut replaced on the end of the crank, place the selector lever to the POWER position and rotate the gears until the crank points straight up. c. See that prick-punch mark on uppermost raised cam surface of clutch sleeve is on centerline of machine. This means that splines are properly engaged. d. Replace gear frame assembly. e. Check alignment of parts. Check that operating crank is in the proper position for throw bar and locking bar. f. Replace and tighten screws finger tight.
If the main gear and crank were removed by simply removing the nut and washers from the top end of the operating crank and pulling the crank out, retiming of the dual control mechanism is required. If retiming is required for any reason, proceed as follows: a. Get the main gear, grease its teeth and bearing surfaces, and place the gear over crank. Insert crank and main gear through bearing on the gear frame. Position gear frame over the base frame and secure. b. Grease sleeve and crank. Position and slide sleeve over crank so that pin marks on both the sleeve and crank are in alignment. c. Position hand throw so that it is perpendicular to the floor (mid-stroke position). Clamp into place with a C-clamp. d. Get the clutch gear, grease teeth and bearing surfaces, and place gear over sleeve such that dog on gear engages the dog on sleeve. (continued on next page)

Place lock washer and nut over stud and tighten. i. Grease bearing and place over bore in plate. Gently tap it into the bore with hammer. j. Remove C-clamp. k. Check that timing is correct:
NOTE 1
Key slot on top of crank should be in line with throw bar.
Middle of stroke positional accuracy only has to be such that machine is in region when cam bar has stopped moving.
NOTE 2
To ensure accurate final roller position, machine should be hand thrown slowly in order to prevent cam bar / roller separation from impact or momentum. Verify no separation has occurred by pushing cam bar against roller.
1. Hand throw switch machine to approximately middle stroke (see notes 1
& 2).
2. Mark the cam bar at this position relative to the base.
3. Hand throw switch machine to normal: hand throw lever fully resting in latch stand (note 2).
4. Measure the displacement of cam bar. The displacement must be 9/16” or greater.
5. Hand throw switch machine back to approximately middle stroke (notes 1

A. APPENDIX A – DRAWINGS
A.1. OVERVIEW
In this appendix the wiring and circuit application diagrams are separated by model designations and presented in this sequence: 5E, 5F, 5G and 5H.
WARNING
IF THE WIRES TO THE SELECTOR-LEVER CONTACT BLOCK
ASSEMBLY HAVE BEEN REMOVED, THE MOTOR CONTROL WIRES
MUST BE RECONNECTED TO THE OUTER CONTACT (THE
CONTACT FARTHEST FROM THE CENTER OF THE MACHINE).
INTERCHANGING MOTOR CONTROL WIRES AND SWITCH
REPEATER WIRES MAY RESULT IN THE MOTOR UNEXPECTEDLY
DRIVING THE HAND-THROW LEVER. WHILE REPLACING THOSE
WIRES, KEEP AWAY FROM SIDE WHERE HAND-THROW LEVER IS
LOCATED, DISCONNECT ALL POWER TO THE SWITCH MACHINE.
