1 INTRODUCTION

1.1 Overview

This document provides the specific guidelines along with Dos and Donts practices for installation, commissioning and adjustment of Multi Section Digital Axle Counter of AzLM system. This document is more of a ready reference hand book for installer and maintainer for the system.

1.2 Recommended Tools

Drilling jig from Alcatel / Chembre Tool Kit ETU001

REFERENCE COUNT DIRECTION (RCD)

The reference count direction (RCD) must be defined for the track layout independent of the direction of travel. The use of RCD ensures that the correct order of counting into and out of a section is maintained throughout a series of detection points. Without the RCD the system cannot be correctly configured. According to figure 1, axles are counted in the section when a train passes Rail Contact1 in the direction of the arrow or a train passes Rail Contact2 in the opposite direction of the arrow. Axles are counted out of the section when a train passes Rail Contact1 in the opposite direction of the arrow or a train passes Rail Contact2 in the direction of the arrow.




2 INSTALLATION OF RAIL CONTACTS (SK30H)

Figure 2: Fitting of Rail Contacts on Rail Web

2.1 Selection of Installation Point on Rail

When choosing the new location for installing Rail Contact, all signalling aspects like overlap, shunting

limits etc. have to be considered. The rail contact is mounted on the rail as shown in Fig. 2 between two sleepers. Any embossments on the rail web must be removed else another location for the rail contact has to be

selected. On double-track lines the rail contact should be mounted preferably on the outside rail.

Recommended spacing 1 m Distance to a rail joint (fishplated or welded or insulating joint)

If the condition of the track is poor, the rail contact should have a distance of approximately 2 m to the next welded rail joint. This is recommended for reducing strain on rail contacts due to vibration.

Mandatory spacing 2 m Distance to the rail contact of same type (Sk30, Sk30H) of a neighbouring detection point. This is recommended for avoiding influence of flux between each other. The operator must ensure that other equipment used or installed at the track does not influence the

correct functioning of the detection points of Zp30H (AzLM) (e.g. detection points of other manufacturers).




2.2 Rail Mounting Holes

It is extremely important that the mounting holes are drilled in the correct position to ensure accurate adjustment of the Rail Contacts and therefore reliable working of the system. The following approximation formula can be used for calculating the height of the holes on the rail web. It is to be noted that all the heights are to be measured from the foot of the rail.

Approximation formula a = (0.409 * h) It is important to note that, this formula is only a general one for an intial guideline. Experience from a pilot installation is more indicative for actual height. Same applies for old rails or rail with other profile.

Figure 3: Drilling Position for installation of Rail Contacts

a = a calculated 1.5 mm a1, a2, a3 must not differ from each other by more than 1 mm. b = 13 mm 0.2 mm c = 148 mm 0.2 mm

As seen in Fig. 3, position "a" of the mounting holes depends mainly upon the height of the rail h. Indicative examples for various rail profiles with a rail height between 140 mm and 180 mm and a rail width between 125 mm and 150 mm are indicated in the following table. They refer to "Flat Bottom" rail profiles as shown in Figure 3. Suitability of other rail profiles such as "Bullhead" or rails with a width less than 125 mm or larger than 150 mm must be individually established.

Rail Profile 90 lb 52 Kg 60 Kg a [mm] 56 mm 63 mm 68 mm

With the calculated dimension "a", the maximum adjustment of the Tx heads should be possible without infringing on the clearance profile or touching the rail.




2.3 Drilling

The final three holes of diameter 13mm are to be made on the rail web. A pilot drill of 6mm or 8mm diameter can be made for convinience.

2.4 Use of Drilling Jig (Recommended)

The drilling jig consists of: Drilling template Mounting device for the drilling machine Templates for the standard rail profiles Fastening device The drilling machine Optionally, drilling machine may be made available from Eldyne.

2.5 Mounting of Rail Contact

The rail contact must be mounted on the rail so that the Tx heads are on the outside and the Rx heads

on the inside of the rail. The heads may get damaged if left loose on the rail. The three M12 bolts must be tightened to 45 Nm by means of an adjustable torque wrench supplied only with the Tool Kit ETU001.

Each Tx head is mounted on an aluminium casting with two M8 bolts. It is important that the teeth and

grooves of the aluminium casting and the Tx head are correctly lined-up. The four M8 bolts must be tightened to 25 Nm by means of an adjustable torque wrench supplied only with the Tool Kit ETU001.

Figure 4: Mounting of Rail Contact

Insulating Plate

Nylon Bush

Nut

Washer

M12 Bolt




Note: After tightening the nuts, the bolts should protrude a minimum of 2mm. If it is less than 2mm the

transmitter head and the aluminium casting must be re-checked for correct fitting. The transmitter head must not touch the rail-head. The brackets for the protective hose must be insulated from the rail. For this purpose nylon bushes are

inserted into the holes of the bracket. The rail contact cables are protected electrically and physically by means of protective hose. Mark the rail contact integral cables, before putting them inside the protective hose, as Sk1 / Sk2

according to reference count direction so that after taking out from the other end of the protective hose, those cables can be identified easily.

The protective hose must be cut to the correct length before the cable is inserted. The hose must be

made watertight with a rubber seal on the rail contact side and the hose clamp on the side of the EAK. The length of the protecting hose must be adequate to ensure that the necessary support for the cable at

the heads is provided and that the hose clamp at the EAK can be correctly installed. Exposed integral cables of rail contact at the Tx & Rx side should have adequate radius of curvature so

as to avoid stress on the cable. Measure should be taken that, this exposed part of the cable does not touch the sharp edge of the ballast.

The integral cables of rail contacts must be laid avoiding loops (i.e. going directly away from the track

and then at a right angle into the electronic unit). The integral cables of the rail contact are available with three different lengths 4m, 5.5m and 8m. Choosing right length of integral cable is very important before installation.

The rail contacts are now ready to get connected to the electronic unit. The cable should not be

shortened. Deflector plates to be installed as shown in figure 5, to protect the rail contacts from hanging metal

objects from passing train.

3. Installation of Track-Side Electronic Unit (EAK)

3.1. Housing Of the Equipment It is strongly recommended to house the EAK in the Mushroom Cover, if installed, out side the location box. EPC 001 CI Lockable Mushroom Cover with SS stand is optionally available from Eldyne. If EAK is placed inside the location box it is recommended to house the EAK with a dust cover also available optionally from Eldyne.

3.2 Connections To obtain the correct direction of counting, an axle counter reference direction has been defined. This would normally be the direction of increasing mileage. The rail contact that is first crossed by an axle in the axle counter reference direction is defined as rail contact 1 (Rx1/Tx1) and the other rail contact as rail contact 2 (Rx2/Tx2). The contacts are connected according to this definition to the terminals of the electronic unit. (see table below).

The screen of the rail contact cables is connected to the earthing bar: Remove the cable insulation for a length of approximately 45mm. Fasten the screen to the earthing bar by means of a cable tie and connect the screen to the earthing bar

using the clip supplied.




The pairs of wire have to be twisted properly as shown in Figure 6.

Fig. 6: Fixing of Rail Contact Integral Cable at EAK Side The connection for Power Supply / Communication to the EAK is furnished in the following table.

Connections Terminals Superimposed Power (+) & Data Line 3 Superimposed Power (-) & Data Line 13

It is mandetory to provide a shorting link between terminal 2 & 1 and 12 & 11 if the same pair of conductors is used for superimposed data & power supply to the EAK. Note: If separate power supply is used for installation, the communication line has to be connected between terminals 3 & 13 and the 60V power supply has to be connected to terminals 1 & 11.




4. Checking Of Power Supply Recommended power supply for track-side electronic unit (EAK) for AzLM is 54 VDC to 72 VDC. The power consumption per EAK is 9W (appoximately). The ripple content of the power supply is recommended to be lower than 24mV peak to peak. Extreme care should be taken to see that the power source does not have any change over time from

mains to battery during mains failure. Care should also be taken to see that power supply does not have any kick beyond upper tolarence

value (72VDC) during startup or charging after power failure. Care should also be taken that power supply source is not under / over loaded beyond its specification. Before installation the available voltages are to be checked at the power supply connectors 1 & 11. This must be ensured that in all the conditions the available power supply voltages should be in the above tolerance limit (54VDC to 72VDC). As there is a SMPS based DC-DC converter in the analog card, it takes much higher current during startup. Therefore care should be taken considering cable resistance and available voltage at the EAK so that the system can start up in a normal way. 5. Earthing of the Equipment The EAK has to be connected to the earth with a copper cable of minimum 25mm2 or an iron cable of minimum 50mm2. Other cross-sections may be necessary due to national regulations. The housing has to be earthed to a suitable low inductance (approximately L

7. Communication Link For communication with the axle counter central evaluator, a physical communication link must be needed. The system uses two wire ANSI T1.601communication protocol with ISDN modulation. The maximum transmission distance is 13KM with a good quality communication cable having maximum resistance of 56ohm/KM and capacitance of 45nF/KM. Though the transmission level of the system is 0dBm, yet a maximum attenuation in the communication link is 24dB. For better reliability the correct pair of star quad cable should be used with proper terminations.

8. ADJUSTMENT OF RAIL CONTACT 8.1 Positioning of Dummy Wheel A dummy wheel is required for the adjustment of the rail contact. On main lines the device is normally set to 40mm. During adjustments the dummy wheel must be kept vertically at the centre of Rx heads.

Figure 8: Positioning of Dummy wheel

8.2 Adjustment with Tool Kit ETU001 For adjustments, tool kit ETU001 (for detailed specification refer Chapter 22) has to be used only with its dummy wheel, true RMS multimeter and adjusteble torque wrench.

Figure 9: Tool Kit ETU001

For adjustment, the test equipment must be connected to the diagnostic port of EAK and the Tx heads are moved upward or downward along the serration, if necessary. The selector switch position 1 shows the value of the output of 1st internal DC-DC Converter (Channel1)

in Analog card. This should be within the range of 22VDC to 35VDC. The selector switch position 2 shows the value of output voltage of 2nd internal DC-DC Converter

(Channel2) in Analog card. This should also be within the range of 22VDC to 35VDC. The selector switch position 4 shows the rectified Rx voltage (MESSAB1) for SK1. This should be positive

without dummy wheel. After placing the dummy wheel on Rx1 vertically on the center, the MESSAB1 voltage should be negative. In ideal condition and for proper adjustment of rail contact, MESSAB1 voltage without dummy wheel should be equal to the MESSAB1 voltage with dummy wheel but having an opposite polarity. The value of MESSAB1 should be within 80mV to 1000mV depending upon the drill position and rail profile.

Steps to adjust the rectified voltage: Turning the potentiometer (R2) on analog board, the rectified voltage without dummy wheel must be set

to positive maximum. The rectified voltage has to be checked with dummy wheel. If there is a big difference between the

positive value and the negative value, the Transmitter head should be taken pulled up or pushed down. Taking the transmitter head upwards increases the negative voltage and decreases the positive voltage and vice versa.

After getting the positive and negative voltages within the specified limit the transmitter head has to be

tightened properly with the torque wrench set at 25 Nm. For proper adjustment the positive voltage should be greater than negative voltage by a value not less than 30mV for achieving suppression of spoke trolley wheels (As shown in Figure 10) so that the rectified Rx voltage does not go to negative (Figure 11) with the specified trolley wheel. It is recommended that the adjustment should be done using a spoked trolley wheel that is normally used in the section. For fine adjustment the potentiometer R2 may be used.

The selector switch position 5 shows the value of reference voltage for SK1 (PEGUE1). This can be

adjusted by the potentiometer R1 on the Analog board and is made equal (or 2%) to the value of MESSAB1 as measured without the dummy wheel.

Keeping the selector switch at position 7, the SK2 is adjusted by measuring rectified Rx voltage for SK2

(MESSAB2) following the same way as mentioned above. For fine adjustment the potentiometer R4 on the Analog board should be used.

The selector switch position 8 shows the reference voltage for SK2 (PEGUE2) and can be adjusted

following the same way as mentioned above using potentiometer R3 on the analog board.




The voltage and frequency of the transmitter heads are to be measured by the true RMS multi meter only. For this purpose additional probe set is provided with ETU001. These readings are available at the connectors of Tx cable for both SK1 and SK2.

11. Axle Counter Central Evaluator (ACE) Axle Counter Central Evaluator is the decision making unit for multi section digital axle counter. It has the following sub components. CPU Card acts as the brain of AzLM. Two CPU Cards are required for 2oo2 system. These CPU Cards have diagnostic interfaces and an alphanumeric display. For a specific application, the CPU Cards used must be loaded with the site specific software. Diagnostic interfaces are available on CPU Card to connect it to a PC and check the system status, health messages etc. with the help of a diagnostic software. Power Supply Card has DC-DC converters. It works on 24VDC and generates 5VDC and 12VDC required for the electronic circuitry. Two Power Supply Cards are required for 2oo2 system. Serial Card receives information from detection points through ISDN communication link and provides this information to CPU Cards. One Serial Card can monitor maximum two detection points. Parallel Card is responsible for providing section information. This card takes instruction from CPU Cards and gives section clear/occupied output through potential free contact of relays in it. The reset of a section is commanded through the Parallel Card. A Parallel Card has two non-vital outputs which are also configurable through site specific software for getting different signals, for example, indication of acceptance of reset by the system or a technical defect in a section etc. All the cards are housed in a SUBRACK. The nomenclature indicates the number of Power Supply and CPU Cards and the number of I/O slots present in the subrack. Different possible configurations are

ACE-2-10 is a 2oo2 system with 10 I/O slots. ACE-2-26 is a 2oo2 system with 26 I/O slots. ACE-2-42 is a 2oo2 system with 42 I/O slots.




12. Connection of ACE

The following connections are to be made during installation of ACE. Power Supply to ACE. Connection to the detection point. Connection of relays.

Figure 14 : Backplane of Axle Counter Central Evaluator ACE-2-10

U1 & U2 are the connectors for 24VDC Supply to ACE. Polarity of the supply should be checked before connection. The slots S01 to S10 are used for I/O cards, either Serial or Parallel depending upon the site specific software. If the second subrack is used to convert an ACE-2-10 to an ACE-2-26, a flat cable with FRC connector of 10 pins is to be connected from C1 connector of the first subrack to the C1 connector of the second subrack as shown in figure 16 (page 21). Each I/O slot has 12-pin WAGO strip connectors numbered from X01 to X12 on the backplane of the subrack. If a Serial Card is plugged into an I/O slot, say slot 1, connectors X01/9 & X01/10 are used for communicating (ISDN) with a detection point. Connections from X01/9 & X01/10 go to Pin14 & Pin15 respectively of the PDCU that is connection with the concerned detection point. Connectors X01/11 & X01/12 of the same I/O slot are used for communicating with another detection point. Connections from X01/11 & X01/12 go to Pin14 & Pin15 respectively of another PDCU that is in connection with the concerned detection point. Connectors X01/5 & X01/6, and X01/7 & X01/8 should be made short with a small looping wire to avoid cross talk between two ISDN communication signal coming from two detection points connected with the same Serial I/O Card.




The pin assignments for a Parallel Card plugged in, say, slot 10, are given below. Connectors X10/1 & X10/2 are used for providing Vital Input No 1 (viz. Preparatory reset). Connectors X10/3 & X10/4 are used for providing Vital Input No. 2 (viz. Hard Reset). Connectors X10/5 & X10/6 are used for providing non-vital output no. 1 (viz. Reset Acceptance). Connectors X10/7 & X10/8 are used for providing non-vital output no. 2 (viz. Technical defect). Both the non-vital outputs give 4-second pulse through opto-coupler for the conditions defined in site specific software. Pull up voltages are required to use these outputs in electronic circuits. Connectors X10/9, X10/10, X10/11 & X10/12 give the vital relay output through the potential free

contact of two relays provided on the Parallel Card. The detail of connections is shown in figure 15. In 2oo2 system two different relays are controlled by two different CPUs and both are supervised by each other. When both relays are picked up only then the vital relay connected externally to the Parallel Card is picked up.

A free wheeling diode (1N 4007) should be connected across the vital relay coil as shown in the figure 15. This will help to protect the Parallel Card from higher voltage generated across the relay coil during the change of position of relay. The contacts of the external vital relay QN1 (8F-8B) can be connected to interlocking as per requirement.

13. Connection of PDCU

PDCU is the interface between outdoor equipment (Detection Point) and indoor equipment (ACE). It has a superimposing circuit for using same conductor for power and data. One PDCU is used for one detection point only. There is a 315mA fuse inside the PDCU. The power to the EAK goes through this fuse and if it is blown then there will be no power at detection point and a red LED within the PDCU will glow.

17. System Diagnosis By Computer For AzLM, the main diagnostic tool is the PC, loaded with a diagnostic software. The diagnostic PC must be a Pentium PC having a serial interface RS-232 (19200 bps) port with Windows operating system. The serial interface has to be connected to the serial interface port on the CPUCard 1 of ACE by a Nullmodem cable. This cable must have female DB9 connector at both ends. After running the diagnostic software, the system data (viz. Elements current data and Historical data) can be downloaded and analysed on the PC. The historical data may be used to reconstruct the sequential occurance of events happened in the AzLM system. The elements data includes status of section, detection point, interfaces, versions etc. The status of elements are displayed on the PC screen in a coded message format with date & time of occurance. The diagnostic messages are explained in the following chapter. Note: The nullmodem cable should always be kept connected at the CPU card end as well at the diagnostic PC end. In case the nullmodem cable needs to get disconnected, it should be disconnected from both ends. It is not recommended at all to disconnect the nullmodem cable from diagnostic PC end but keep it connected at the CPU card end.







17.1 Important Diagnostic Messages The following format of diagnostic messages is used in the history files and element data files generated by the diagnostic tool. RNr CPU number from where the diagnostic messages are read out. Replica 0 Message from all running CPUs

1 Message from CPU1 (that is, CPU Card on left side of ACE subrack) 2 Message from CPU2 (that is, CPU Card on right side of ACE subrack) 3 Message from CPU1 and CPU2

Date/Time Date and time of occurrence of diagnostic event. Element Type There are several element types, e.g., section,detection point, parallel I/O card, serial I/O card etc. Element Number Each element has its own number (e.g., n=1, 2, ) which is specified in the site specific data. These element numbers are listed in

the element window of the diagnostic tool together with the names which are used in the layout plan. Diagnostic Event There are five types of diagnostic events, namely, operational name, site specific data, state, version and axles. Parameter Information about different events. RNr Replica Date/

Fig. 25: Front Panel of Reset Box (ERBM-02)

ERBM-02 is the reset box for Alcatels Multi Section Digital Axle Counters AzLM. it provides the basic resetting pulse (24VDC) for 3 seconds (approximately) to ACE to reset a particular section. The front panel of the terminal consists of: 1. PUSH SWITCH 2. RESET COUNTER 3. PREPARATORY RESET INDICATION GREEN LED 4. LINE VERIFICATION INDICATION YELLOW LED 5. SECTION CLEAR / UNOCCUPIED INDICATION - GREEN LED 6. SECTION CLOSED / OCCUPIED INDICATION - RED LED

Fig. 26: SMs Key Module The SMs Key module for multisection reset panel consists of: 1. Reset Key 2. Power On LED Indication (Yellow LED) This Reset Key acrs as the common key for all the reset boxses used in a particular installation. Additionally a buzzer is provided to give audio indication that the 3-second reset pulse is on.

SMs Key

Following steps are to be followed to initiate a reset.

1. The authorized person inserts the KEY, turns it clockwise and then pushes. (If optional Cooperative reset key is provided this has also to be turned simultaneously by another authorized person. For this H & R are to shorted at selection jumper J1 on PCB. If the cooperation / line verification is not required then P & R are to be shorted).

2. While KEY is in turned position the RESET PUSH BUTTON for a specific section is pressed

momentarily.

3. BUZZER sounds for 3 seconds and then stops.

4. The KEY is then turned back anti-clockwise and taken out. A reset operation is only possible when section is occupied or disturbed. When reset is initiated for a straight line section, that is assigned for preparatory reset in the site specific software, and the system accepts the reset, ERBM-02 front panel indicates that the system is under Reset State by means of the PREPARATORY RESET (Green) LED. The SECTION OCCUPIED (RED) LED also glows indicating that the system is waiting for a train movement through the section. With the passage of a train through the section with equal count in and out of (>1) axles, the system commands the vital relay to pick up. Contacts of this vital relay change the status of the OCCUPIED (red) LED to OFF and CLEAR (green) LED to ON indicating that the section is now CLEAR. The RESET ON LED also goes OFF indicating reset is successfully completed. If the section is a point zone, that is assigned for hard reset in the site specific software, the vital relay picks up immediately after commanding the reset provided there is no technical defect in the system. Each reset is registered in the sealed reset COUNTER unit. The count increases by one after each reset commanded by the operator. Each train, now moving into the section, is indicated by the OCCUPIED (RED) LED. A complete passage of a train out of the section is indicated by the CLEAR (GREEN) LED. ERBM-02 is very compact yet extremely rugged. It is simple to install and operate. The unit is housed in heavy sheet metal with scratchproof powder coated finish. Wedged mounting base gives the front panel comfortable view and ease of operation for the operator. The detachable top cover is locked at the rear and makes ERBM-02 tamper proof, yet accessible only to authorized service personnel if required. The field cables have their entry from the back through cable gland and are terminated at cage clamp type Wago terminals.

Only serviceable parts inside ERBM-02 two 500mA slow blow glass cartridge fuses.

EAK 0.17A 19.1 Indoor Equipment (Example) In AzLM system, the indoor equipments, that is, ACE, vital relay and reset box, work on 24VDC. Based on the above table, an AzLM system having 8 detection points, 6 sections with one ACE-2-10 central evaluator will consume a maximum current of 4.82A. Therefore the indoor fuse for 24VDC main power supply should be of 5A. 19.2 Outdoor Equipment (Example) In AzLM system, the outdoor equipment, that is, EAK, work on 60VDC. Based on the above table, the outdoor equipment, i.e. the EAKs of an AzLM system having 8 detection points will consume a maximum current of 1.36A. Therefore the indoor fuse for 60VDC mains power supply should be of 2A.
