NOTEThe operation of the MICROLOK II Development System is described ingreater detail in SM-6800C. A feature of the Development System that isof particular use in troubleshooting is the System Event Log. The SystemEvent Log indicates the presence, warnings, and errors of any faultyMICROLOK II I/O PCBs.

US&S does not provide shop maintenance procedures for the MICROLOK II system circuit boards.The boards are not repairable in the field.

1.1 Overview of New Executive Features

1.1.1. Vital Isolated Output BoardVersion 8.00 of the MICROLOK II Executive supports a new vital isolated output board (OUT8.ISO)that provides eight isolated outputs. The vital isolated output PCB provides eight vital isolated outputsfor double break control of relays and bipolar relays.

Introduction

1-2 SM-6800L, Original, January 2005

1.1.2. LAMP16 BoardVersion 8.00 of the MICROLOK II Executive includes support for GELcore Railway RM4 series LEDsignals with 12-Volt module, Revision C. Contact US&S Customer Service for specific details andlimitations.

Version 8.00 of the MICROLOK II Executive eliminates critical errors when the LAMP16 board isconfigured to operate in MODE 0 and low lamp current is detected. Low lamp current is now loggedas a warning when MODE 0 operation is selected.

1.1.3. ECode Track BoardVersion 8.00 of the MICROLOK II Executive includes a new feature that is intended to prevent ECodetrack code dropouts that may occur when transmitted track codes are changed quickly.

The ECode track driver has been enhanced to allow the application programmer to directly determinewhen a transmitted track code becomes valid. A new system bit (CODE.VALID) is set for eachECode track after a newly selected track code has been sent at least twice. The applicationprogrammer may use this bit in logic equations as desired to insure that a selected track code is alwayssent enough times to be registered as valid by the receiver at the other end of the track.

A second new system bit (VALIDATE.CODE) may be set for each ECode track by the applicationprogrammer to ensure that any track code that is sent once is sent twice. This bit automatically forcesvalidation of transmitted track codes without specific intervention by the application programmer.

Version 8.00 of the MICROLOK II Executive also supports "pre-shunt" detection for ECode trackcircuits to allow faster, non-vital detection of track shunt. When the ECode receiver detects a missingtrack code, a new system bit (NV.QUICK.SHUNT) is set for the track. This bit may be used by theapplication programmer in logic equations to facilitate faster non-vital detection of a track shunt.

1.1.4. MICROTRAX Track BoardVersion 8.00 of the MICROLOK II Executive includes a new feature that is intended to preventMICROTRAX track code dropouts that may occur when transmitted track codes are changed quickly.

The MICROTRAX track board driver has been enhanced to allow the application programmer todirectly determine when a transmitted track code becomes valid. A new system bit (CODE.VALID) isset for each MICROTRAX track after a newly selected track code has been sent at least twice. Theapplication programmer may use this bit in logic equations as desired to ensure that a selected trackcode is always sent enough times to be registered as valid by the receiver at the other end of the track.

A second new system bit (VALIDATE.CODE) may be set for each MICROTRAX track by theapplication programmer to ensure that any track code that is sent once is sent twice. This bitautomatically forces validation of transmitted track codes without specific intervention by theapplication programmer.

Version 8.00 of the MICROLOK II Executive also supports "pre-shunt" detection for MICROTRAXtrack circuits to allow faster, non-vital detection of track shunt. When the MICROTRAX receiverdetects a missing track code, a new system bit (NV.QUICK.SHUNT) is set for the track. This bit maybe used by the application programmer in logic equations to facilitate faster non-vital detection of atrack shunt.

Vital Isolated Output Board


2. Vital Isolated Output Board (OUT8.ISO)2.1. IntroductionVersion 8.00 of the MICROLOK II Executive provides support for the vital isolated output PCB(OUT8.ISO). Older versions of the MICROLOK II Executive software will not support the vitalisolated output PCB. The vital isolated output PCB provides eight vital isolated outputs.

2.2. Functional DescriptionThe vital isolated output PCB (Figure 2-1) provides eight vital isolated outputs for double breakcontrol of relays and bipolar relays. Each output provides a positive (+) and a negative (–) connectionthat is isolated from the house battery and other outputs.

The eight outputs are jumper selectable (JP1 – JP8) to drive normal vital relays or outputs can becombined to drive bipolar relays. Always verify that jumpers JP1 – JP8 are in the correct positionbefore installation and applying power.

Output voltage is dependent on two factors, isolated output battery source and load resistance. Thespecifications for these boards are listed in Table 2-3.

Outputs are controlled by “high side” software-controlled switches. Loads should be connectedbetween the positive (+) and negative (–) connections provided on the upper 48 way connector. Thewiring diagrams in Figure 2-2 and Figure 2-3 shows the pin out and jumper selection for normal loads.

Pairs of outputs can be wired to be configured as bipolar relay drive. Outputs 1 and 2 are used for asingle bipolar drive as are 3 and 4, 5 and 6, 7 and 8. The wiring diagrams in Figure 2-4 and Figure 2-5shows the pin out and jumper selection for bipolar loads. When using bipolar drive, only one of theoutputs of any bipolar pair can be assigned to be on at any given time.

CAUTION

Damage may occur if Jumpers JP1 – JP8 are set incorrectly. Verifycorrect settings before installation.

Each output is protected with a polyswitch, which acts like a circuit breaker. When the over currenttrip point is reached (approximately 0.75amp), the polyswitch switches to a high impedance. Theswitch resets to its normal low impedance when the additional load or short is removed. Shortedoutputs will not cause any damage to the board and will not be detected in the System Event Log of theMICROLOK II Maintenance Tool.

CAUTION

BVCOR2 is vital battery to power the isolated sections of the outputcircuitry. When JP9 is cut, (refer to Figure 2-3 or Figure 2-5), thebattery connected to BVCOR2 is independent but not isolated fromthe battery connected to BVCOR1. While BVCOR1 must be withinthe voltage range of the specified board, BVCOR2 does not have tobe with in the voltage range.

There are two inputs for vital battery provided on the upper 48-way connectors labeled BVCOR1 andBVCOR2. BVCOR1 and BVCOR2 are connected together by a wire jumper, JP9, located on the rearof the board between the upper and lower connectors. (Refer to Figure 2-6 for the location of jumperJP9.)

BVCOR1 is vital battery to the output circuitry and it must be in the range of the rating of the boardbeing used. N17065801 is a 12-volt version of the OUT8.ISO board, and the battery must be between9.8 and 16.2 volts. N17065802 is a 24-volt version of the OUT8.ISO board, and the battery must bebetween 18 and 32 volts.

BVCOR2 is vital battery to power the isolated sections of the output circuitry. When JP9 is cut, (referto Figure 2-3 or Figure 2-5), the battery connected to BVCOR2 is independent but not isolated fromthe battery connected to BVCOR1. While BVCOR1 must be within the voltage range of the specifiedboard, BVCOR2 does not have to be with in the voltage range. For example, for a 12-volt version ofthe OUT8.ISO board (N17065801), BVCOR1 must be between 9.8 and 16.2 volts, but BVCOR2 canbe anywhere between 9.8 and 32 volts.

For a typical installation using a single battery, the vital battery source from the VCOR will be appliedto BVCOR1 (pins A24 and C24) input and jumper JP9 will be installed.

There are multiple pins for both BVCOR1 and BVCOR2 provided on the upper 48-way connector.Multiple pins are only required if more than one of the outputs is driving the lowest specified load andthey can be on at the same time.

For more information on upper connectors, refer to Section 2.3.1.

2.2.1. Noise Protection

2.2.1.1. Relay Coil SnubRelay snubs are intended to dissipate large electromagnetic surges from the coil inductance and toprevent these surges from interfering with normal operation of the MICROLOK II system. It isrecommended that all relays being driven by MICROLOK II be snubbed to prevent unwanted monitor



errors. This is particularly true where the coil load to the MICROLOK II relay driver is being brokenby a series contact.

Relay snubs can also be installed on other relays that are not directly controlled by MICROLOK IIoutputs, but may be contributing to possible noise due to their close proximity to the MICROLOK IIwiring.

US&S recommends the use of transorbs (J792736-0002) for relay snubbing. They will have minimaleffect on relay timing.

Resistors are also suitable relay snubs. When using a resistor loading of the MICROLOK II output aneffect on timing (relay drop away) must be considered.

Diodes can also be used as snubs but:

1. They will definitely increase relay drop time.

2. They may cause contact burning in some circuits.

WARNING

Do not use diodes or any devices that could function as a diode in AC orDC electrified territory; otherwise, voltage induced by the device couldcause a relay to remain falsely energized.

2.2.1.2. Twisted WireUS&S recommends the use of twisted pair wiring (two to three turns per foot) for all relay loads tominimize possible noise. This should be done wherever possible on all I/O wiring.



2.2.1.3. Wire SeparationUS&S recommends the physical separation of clean and dirty wiring. Ideally, all outputs are gatheredin a bundle, inputs are gathered in a bundle, and power wiring is gathered in a bundle. Each of thesebundles is physically separated from each other (6” preferred) and all bundles are physically separatedfrom other house wiring. It is particularly important to maintain this physical separation from high-current “dirty” wiring.

2.3. Front Panel DescriptionThe front panel houses eight yellow LED’s (OUT1 – OUT8), which are illuminated when the outputhas been requested to turn on. The OUT8.ISO PCB front panel is shown in (Figure 2-7).

2.3.1. Upper-Rear ConnectorThe upper-rear connector is a 48-pin DIN 41612 Type E connector used for field wiring. Pins on thisconnector also supply the board with its cardfile slot address, which is assigned via jumpers that resideinside the cardfile-mounted housing of the connector's mating half.

Note that the jumper settings must match the board address found in the .mll application file listing.Details for correctly installing the jumpers (as well as additional information about the upperconnector) can be found in the MICROLOK II Hardware Installation Manual (SM 6800B).

Connection diagrams for the upper-connector is shown in Figure 2-2, Figure 2-3, Figure 2-4, andFigure 2-5.

2.3.2. Lower-Rear ConnectorThe lower-rear 96-pin DIN connector on the OUT8.ISO PCB plugs into the MICROLOK II cardfilemotherboard to interface with the internal bus system. Mounted alongside the connector is the 12-tabmale keying strip. Tabs on this keying strip are removed at the factory according to a specific pattern,which identifies the particular PCB. PCB keying information is shown in Table 2-1.

Each MICROLOK II cardfile motherboard has a 96-pin lower connector for each PCB slot. A femalekeying guide is installed alongside the connector. At the field location, once the cardfile PCBconfiguration has been determined, the guide is used to ensure proper PCB placement in the cardfile.Keying plugs (Part # J709146-0473) are inserted into the MICROLOK II cardfile motherboard keyingguide to match the tab pattern of the particular PCB to be installed into that cardfile slot. Table 2-1lists the keying plug locations for a slot occupied by an OUT8.ISO PCB.

Figure 2-8 illustrates the process of keying plug installation. A pair of needle nose pliers can be usedto remove a keying plug in the event one should need to be removed.

TYPE: OUT8.ISOOUTPUT: <output bit list>;

The OUTPUT section must be defined. The OUTPUT statement can define a maximum of eight bits.

2.7. Configuring Boards And Displaying Status InformationThe MICROLOK II Development System provides two options related to OUT8.ISO Boards:

• Configuring OUT8.ISO Boards

• Displaying OUT8.ISO Board status information

These two options are described in the sections below.

2.7.1. Configuring OUT8.ISO BoardsThe Development System provides options for system-configuration activities. On the program’s“System Configuration” screen, the button indicated in Figure 2-9 initiates board configuration.

The screen shown in Figure 2-9 will display a selection button for each OUT8.ISO Board that isdefined in the application. You can configure an OUT8.ISO board by clicking on the appropriateselection button. The only configuration activity that can be performed on an OUT8.ISO Board is theenabling or selectively disabling of the board.

NOTEThe board enable option is user-configurable via the development systemprogram only if the option is identified as an adjustable parameter in theapplication software.



Figure 2-9 - OUT8.ISO Button on a System Configuration Screen

The following procedure describes how to configure an OUT8.ISO Board.

1. To configure an OUT8.ISO Board, click on the selection button for the appropriate board on theSystem Configuration selection screen. After the button has been clicked, the dialog box that isshown in Figure 2-10 will appear.

2. Ensure that a check mark appears in the “ENABLE” selection box at the top of the screen. Ifnecessary, click on the “ENABLE” selection box to insert a check mark.

3. After the board has the proper values for the application, click on the “DONE” button in the lower-left corner of the screen. After the “DONE” button has been clicked, the confirmation dialog boxthat is shown in Figure 2-11 will appear. The confirmation dialog box will list the changes thathave been initiated, and confirmation of the changes is requested.

4. Click on the “YES” button on the confirmation dialog box to complete the board configuration.The Development System will redisplay the system configuration selection screen (Figure 2-9).

5. Repeat the above steps for each OUT8.ISO Board in the cardfile that needs to be configured.

2.7.2. Viewing the OUT8.ISO Board Status DisplayIn addition to providing system-configuration activities, the Development System allows users to viewboard status displays of the individual I/O boards that are defined in the application. To view a board’sstatus display, click the “Board Information” button on the main screen of the Development System.After the “Board Information” button has been clicked, a “Board Information” screen, like the one inFigure 2-12, will appear.

Since there are no statistics or other parameters to view on the OUT8.ISO Board, the button for theOUT8.ISO Board is disabled, or grayed out. The button is still present to let the user know that theOUT8.ISO Board is defined in the application and it is enabled.

LAMP16 Board


3. LAMP16 Board3.1. New FeaturesVersion 8.00 of the MICROLOK II Executive includes the ability to drive GELcore Railway RM4Series, 12V, Revision “C”, LED Signals. No other revision of the GELcore RM4 Signal, nor any otherbrand or model of LED signal is supported at this time.

The LED signals must be powered from a 12 VDC source, typically this will be the system’s battery.LED signals must be located no farther than 1500 feet from the LAMP16 board (3000 loop feet ofwire). Battery supply voltage and wire gauge must be selected to ensure that an absolute minimum of1.2 amps of current flows to an “ON” LED signal. Failure to provide 1.2 amps of current can damageGELcore signals. (Refer to GELcore document INST001-RM4, dated June 8, 2004).

Slide-wire resistors are not required and must not be used with GELcore LED signals.

The LAMP16 board can operate in two modes, MODE 0 and MODE 1. MODE 1 operation will be themost reliable mode of operation. MODE 0 is fully supported and can be used if required. If usingMODE 0, the application program should designate GELcore red and green signals as 13-watt loads.In MODE 0, yellow and white GELcore signals may operate better when designated as 16- or 18-wattloads, when battery voltage is low or the distance from the LAMP16 board is greater than 1000 feet.For this reason, it is suggested that the application programmer designate ALL GELcore LED signalsas ADJUSTABLE. This will allow the most appropriate wattage range to be selected at the track site.This is not a concern in MODE 1, as all loads (except the 36-watt loads) are tested to the same currentlimits. The MODE 0, 13-watt load setting, may be used to drive an incandescent lamp if required. InMODE 0, a 13-watt load must draw at least 1.2 amps and no more than 1.9 amps when “ON”.

3.2. Application LogicBoard Type LAMP16

Address Class: 16 Bit VPA

A definition of this type of card looks like:

BOARD: <USER NAME>

[ADJUSTABLE|FIXED] ENABLE:<FLAG>

TYPE: LAMP16

[ADJUSTABLE | FIXED] [[13 | 16 | 18 | 24 | 25 | 36 ] WATT] [MODE [0|1]]

Multiple OUTPUT statements, each with different wattages, can be specified. The first output on thecard is associated with the first bit in the first OUTPUT statement. Outputs on the card are associatedby increasing number to bits in OUTPUT statements left to right and then in the order of the OUTPUT

statements. An additional wattage, 13-watt, can now be defined to drive GELcore Railway RM4Series, 12V, Revision “C”, LED Signals. No other revision of the GELcore RM4 Signal, nor any otherbrand or model of LED signal is supported at this time.

If no wattage specifiers are present, the compiler assumes a default value of 18 watts.

The MODE clause defines the value of the configuration parameter that controls the operation of lampdiagnostics. (See manual SM6800C, Section 6.2.12.1.) It is a byte whose values are limited to 0 or 1.This parameter’s adjustability is the same as the lamp wattage in the same OUTPUT statement. If noMODE clause is specified, a value of 0 will be assumed along with any adjustability attribute for thatoutput.

ECode Track Board


4. ECode Track Board4.1. New FeaturesVersion 8.00 of the MICROLOK II Executive includes two new system bits associated with eachECode track. Bits <board_name>.<track_name>.VALIDATE.CODE and<board_name>.<track_name>.CODE.VALID are provided to help eliminate momentary loss of vitaltrack codes when transmitted codes are quickly changed.

CODE.VALID is set by the ECode transmitter after the currently selected VITAL track code has beensent twice. Setting of this bit indicates that the receiver at the other end of the track circuit has had theopportunity to receive and decode the track code currently being transmitted. This bit may be used inlogic equations to sequence transmitted track code changes in an orderly manner.

VALIDATE.CODE may be set by the application programmer to force any selected VITAL code thatis transmitted once to be transmitted a second time. The application programmer uses this bit when theprogrammer desires that the ECode track transmitter handle track code validation automatically. Thevalue of VALIDATE.CODE may be changed at any time during the execution of the applicationprogram. When it is not set, the ECode track transmitter functions as in previous versions of theMICROLOK II executive. That is, transmitted code changes become effective immediately whentransmission of the next code cycle is started.

Version 8.00 of the MICROLOK II Executive also supports "pre-shunt" detection for ECode trackcircuits to allow faster, non-vital detection of track shunt. When the ECode receiver detects a missingtrack code, a new system bit (NV.QUICK.SHUNT) is set for the track. This bit may be used by theapplication programmer in logic equations to facilitate faster non-vital detection of a track shunt.

4.2. Application LogicBoard Type: ECODE.TRACK

NOTEThere are new compiler defined system bits for this board that are of useto the application programmer, VALIDATE.CODE and CODE.VALID.These system bits are provided to help eliminate momentary loss of vitaltrack codes when transmitted codes are quickly changed.

MICROTRAX Track Board


5. MICROTRAX Track Board5.1. New FeaturesVersion 8.00 of the MICROLOK II Executive includes three new system bits associated with eachMICROTRAX Track Board. Bits <board_name>.<track_name>.VALIDATE.CODE and<board_name>.<track_name>.CODE.VALID are provided to help eliminate momentary loss of vitaltrack codes when transmitted codes are quickly changed. The<board_name>.<track_name>.NV.QUICK.SHUNT bit is provided as an indication of a possible shuntdue to a missed message.

CODE.VALID is set by the MICROTRAX transmitter after the currently selected VITAL track codehas been sent twice. Setting of this bit indicates that the receiver at the other end of the track circuithas had the opportunity to receive and decode the track code currently being transmitted. This bit maybe used in logic equations to sequence transmitted track code changes in an orderly manner.

VALIDATE.CODE may be set by the application programmer to force any selected VITAL code thatis transmitted once to be transmitted a second time. The application programmer uses this bit when theprogrammer desires that the MICROTRAX track transmitter handle track code validationautomatically. The value of VALIDATE.CODE may be changed at any time during the execution ofthe application program. When it is not set, the MICROTRAX track transmitter functions as inprevious versions of the MICROLOK II executive. That is, transmitted code changes become effectiveimmediately when transmission of the next code cycle is started.

The NV.QUICK.SHUNT system bit provides an indication of a possible shunt condition by reacting tothe first missed message. The track shunt status bit, the track NORMAL bit, is cleared when the unithas missed two messages indicating a track shunt. The NV.QUICK.SHUNT bit, which is normallyclear and is set to indicate a shunt condition, is set when the first message is missed. This will allowthe application logic to have access to possible shunt conditions 6 seconds earlier than with the trackNORMAL bit. The NV.QUICK.SHUNT bit also provides an early indication of the removal of ashunt. Currently, the track LINKUP bit is set when the linkup code is received and remains high untila valid user code has been received. This is on the first message for the TUMBLE.DOWN and SLEEPcodes and on the second message for all other codes. The NV.QUICK.SHUNT bit is always clearedwhen the first message containing a user code is received. This will be at the same time the NORMALbit is set for the TUMBLE.DOWN and SLEEP codes and one message before the NORMAL bit is setfor all other codes. The NV.QUICK.SHUNT bit is set by the system and is read only for theapplication logic.

5.2. Application LogicBoard Type TRX.TRACK
