Product Description
After reading this chapter, you should be able to identify the product features and system applications.
The Bulletin 1402, Line Synchronization Module (LSM), is designed to meet the needs of manufacturers, system integrators, and users of 3 phase alternators and cogeneration systems or for applications that require two three–phase systems to be synchronized with each other. The module provides means for automatic synchronization, load sharing, and high speed power system monitoring.

General Description

The Line Synchronization Module (LSM) is a two slot 1771 form factor module that fits into a standard Allen–Bradley 1771 I/O chassis. It performs three functions:
1. Measures appropriate parameters from the two three–phase systems and provides control and error signals to implement engine governor control for synchronization.
2. Provides an analog output that is representative of the ratio of the power being supplied by the alternator to the output rating of the alternator, reads an analog input that represents the ratio of the total system load being supplied to the total system capacity, and provides an error signal to adjust the alternator for proper load sharing based on the instantaneous load requirements.
3. Performs as a multi–function digital power monitor for the system.
These functions provide data and control signals which are communicated to the PLC-5 via the 1771 backplane.

Product Description

Synchronization and Load Share Errors

In order to synchronize two three phase systems without high instantaneous energy transfer, the voltage, frequency, and phase displacement of the two systems must be matched. Kilowatt Load Sharing can be implemented by matching the ratio of power system load to system capacity to the ratio of actual alternator power to rated alternator power. The LSM provides the following information to allow the user’s system to achieve the necessary control actions.
Voltage Match Error (in steps of 0.05 percent)
Frequency Match Error, or slip (in steps of 0.01 Hz)
Synchronizing Bus to Reference Bus Phase Match Error (in steps of 1
degree)
Load Sharing Error (scalar quantity between 0.000 and 1.000)

Module Configuration

All voltage and current measurements are true RMS. The power measurements are calculated from the instantaneous voltage and current measurements. The remainder of the monitoring information is derived from these values.
Before the LSM can perform its intended functions, it must be configured by the user. The module is configured by providing the required data via a block transfer to the module. The block transfer data can be entered into the PLC-5 manually or with the 6200 Version 4.4 I/O Configuration Software. The 6200 Software can also be used to monitor the operation of the module.

Installation
The Bulletin 1402 Line Synchronization Module (LSM) should be installed in a Bulletin 1771 I/O chassis that is located in a dry, dirt free environment away from heat sources and very high electric or magnetic fields. The module is designed to operate in an ambient temperature between 0 and 60° Celsius. The LSM is typically installed in a local rack in order to maximize data transfer rates.
This equipment is classified as open equipment and must be installed (mounted in an enclosure during operation as a means of providing safety protection. The enclosure chosen should protect the LSM from atmospheric contaminants such as oil, moisture, dust, corrosive vapors, or other harmful airborne substances. A steel enclosure is recommended to guard against EMI (Electromagnetic Interference) & RFI (Radio Frequency Interference).

Mounting

Power Supply

Chassis Grounding

The enclosure should be mounted in a position that allows the doors to open fully. This will allow easy access to the wiring of the LSM and related components so that servicing is convenient.
When choosing the enclosure size, extra space should be allowed for associated application equipment such as, transformers, fusing, disconnect switch, master control relay, and terminal strips.
The LSM mounts in two slots of a Bulletin 1771 Series B, I/O chassis. Mounting dimensions will vary with the size of the chassis selected. Refer to the appropriate 1771 literature for specific dimensions.
The LSM backplane power requirement is 1.1A at 5V DC. Refer to the appropriate 1771 literature for additional information on available power supply current.
For correct and reliable performance, the grounding recommendations specified for Allen–Bradley PLC systems must be followed.

Swing Arm

Wiring

The LSM requires the use of a Cat. No. 1771-WC (10 position, gold contacts) Swing Arm.
There are two sets of terminals associated with the LSM; a 10 position swingarm and an 8 position fixed terminal block. All customer wiring to the LSM is accomplished via these terminals on the front of the module. The 10–position swingarm is used to make all of the voltage (PT) connections to the module as well as the Load Share connections. These connections are designed to accommodate wire size 0.5 mm

mm
(14 AWG). The 8–position fixed terminal block is used to make all of the current (CT) connections. These connections are designed to accommodate gauge wire size 0.5 mm
3.25 mm Phasing and polarity of the AC current and voltage inputs and their
relationship are critical for the correct operation of the unit. Figure 2.1 through Figure 2.5 shown on Pages 2–7 through 2–11 provide wiring diagrams to help ensure correct installation.
Two (2) conductor shielded wire (22 gauge or greater) should be used for Load Share wiring. The shield shall be grounded at the PLC Chassis ground point only.

Installation

PT and CT Transformer Selection

For proper monitoring and synchronization, correct selection of current transformers (CT’s) and potential transformers (PT’s) is critical. The following paragraphs provide the information required to choose these transformers. Also refer to transformer operational characteristics Pages 3–2 and “Factory Configuration Parameters” listed on Page B–2.
PT Selection
The LSM is designed for a nominal full scale input voltage of 120V AC. The user must supply transformers to scale down the system L–N (Wye) or L–L (Delta) voltage to the full scale input rating of the module. The PT’s should be selected as follows:
Wye (Star) Configuration – PT primary rating = L–N voltage or nearest
higher standard size. PT secondary rating = 120 Volts.
Delta or Open–Delta Configuration – PT primary rating = system L–L
voltage. PT secondary rating = 120 Volts.
PT quality directly affects system accuracy. The PT’s must provide accurate linearity and maintain the proper phase relationship between voltage and current in order for the Phase Error, Volts, kW, and Power Factor readings to be valid. Instrument accuracy Class 1 or better is recommended. The LSM PT inputs represent a O.O2 VA burden.
CT Selection
The LSM uses current transformers (CT’s) to sense the current in each phase of the power feed from the synchronizing voltage source, and may optionally be included in the ground or neutral conductor. The precision of the selected CT’s will directly affect the device accuracy.
The CT secondary should have a rating of 5A full scale and a burden capacity greater than 3VA. The LSM Module CT Inputs represent a burden of 0.0025VA.
ATTENTION: The CT primary rating is normally selected to be equal to the current rating of the power feed protection device. However, if the peak anticipated load is much less than the rated
!
system capacity, then improved accuracy and resolution can be obtained by selecting a lower rated CT. Generally, the CT size should be the maximum expected peak current +25%, rounded up to the nearest standard CT size.

Chapter 2
PT an
ing Connections
Installation
Other factors may affect CT accuracy. The length of the CT cabling should be minimized because long cabling could contribute to excessive power load on the CT and inaccuracy. The CT burden rating must exceed the combined burden of the LSM plus cabling plus any other devices connected in the measuring circuit (burden is the amount of load being fed by the CT, measured in Volt–Amps calculated at 5A full scale.).
Overall accuracy is dependent on the combined accuracy of the Bulletin 1402, the CT’s, and the PT’s. Instrument accuracy Class 1 or better is recommended.
ATTENTION: A CT circuit must not be opened under power. Wiring between the CT’s and the LSM should include a terminal
!
block for shorting the CT’s. Open CT’s secondaries can produce hazardous voltages, which can lead to personal injury or death, property damage or economic loss.

Connection for Three Phase WYE (Star), 4 Wire Systems
Figure 2.1 shown on Page 2–7 provides a wiring diagram for 4–wire WYE (Star) systems. The “Voltage Mode” of the LSM should be set to “1” (as described in Chapter 3, “General Operation”) for 4–wire WYE systems.
The LSM senses the line to neutral (or ground) voltage of each phase. The PT primaries and secondaries must be wired in a WYE (Star) configuration as shown in the figure. Voltage input leads should be protected by circuit breakers or fuses at their source. If the power rating of the PT’s is over 25 Watts, secondary fuses should be used. Wiring and polarity marks must be exactly as shown for correct operation.
Connection for Three Phase WYE (Star), 3 Wire Systems
Figure 2.2 shown on Page 2–8 provides a wiring diagram for 3–wire WYE (Star) systems. The “Voltage Mode” of the LSM should be set to “1” (as described in Chapter 3, “General Operation”) for 3–wire WYE systems.
The LSM senses the line to neutral voltage of each phase. The PT primaries and secondaries must be wired in a WYE (Star) configuration as shown in the figure. Voltage input leads should be protected by circuit breakers or fuses at their source. If the power rating of the PT’s is over 25 Watts, secondary fuses should be used. Wiring and polarity marks must be exactly as shown for correct operation.

Connection for Three Phase Delta, 3 Wire Systems with 3 PT’s & 3 CT’S
When configured for ungrounded (floating) Delta operation, the LSM senses the L–L voltages between each of the phases. The “Voltage Mode” of the LSM should be set to “2” (as described in Chapter 3, “General Operation”). Figure 2.3 shown on Page 2–9 provides the wiring diagram for this configuration. Wiring and polarity marks must be exactly as shown for correct operation.
Connection for Three Phase Open Delta, 3 Wire Systems with 2 PT’s & 3 CT’S
When configured for ungrounded or Open Delta operation, the LSM senses the L–L voltages between each of the phases. The “Voltage Mode” of the LSM should be set to “4” (as described in Chapter 3, “General Operation”). Figure 2.4 shown on Page 2–10 provides the wiring diagram for this configuration. Wiring and polarity marks must be exactly as shown for correct operation.
Connection for Three Phase Open Delta, 3 Wire Systems with 2 PT’s & 2 CT’S
When configured for ungrounded (floating) Open Delta operation, the LSM senses the L–L voltages between each of the phases. The “Voltage Mode” of the LSM should be set to “4” (as described in Chapter 3, “General Operation”). Figure 2.5 shown on Page 2–11 provides the wiring diagram for this configuration. Wiring and polarity marks must be exactly as shown for correct operation.
Neutral Connection
The voltage reference terminal, “Neutral”, of the LSM serves as the zero voltage reference for voltage readings. A low impedance Neutral connection is essential for accurate measurement. The length of the wire should be as short as possible. It should be made using a dedicated size 2.0 mm AWG) wire, or larger, to a point in close proximity to the LSM. This will provide minimal voltage error due to other distribution voltage drops.
The connection point for “Neutral” is the point where the PT secondary leads are common.

Installation
Current Transformer Connections
The LSM is equipped with four CT inputs, designated I1 – I4. Inputs I1 – I3 are used to measure the current in the synchronizing circuit. These inputs are wired as shown on Pages 2–7 through 2–11 in Figure 2.1 through Figure 2.5. Input I4 is optional and is typically used to measure current in the neutral or ground conductor. The primary rating for I4 can be different than the primary rating for transformers I1 – I3. However, the secondary rating for all of the CT’s must be 5 Amps.
Current connections may remain unused for a system that only performs synchronization. Unused terminals should be wired to chassis ground for noise immunity.

Maintenance

Calibration

Field
Service Considerations
The LSM does not require any special maintenance.
The calibration interval for the LSM depends on the user’s accuracy requirements. To meet general operating requirements, regular calibration is not necessary.
Contact your nearest Allen–Bradley Sales Office for calibration or service information.
If the LSM requires servicing, please contact your nearest Allen-Bradley Sales Office. To minimize your inconvenience, the initial installation should be performed in a manner which makes removal easy.
1. A CT shorting block should be provided to allow the LSM current inputs
to be disconnected without open circuiting the user supplied CTs. The shorting block should be wired to prevent any effect on the external protective relays.
2. All wiring should be routed to allow easy maintenance at connections to
the LSM terminal strips, the swing-arm, and the LSM itself.
2–6
ATTENTION: A CT circuit must not be opened with primary current present.. Wiring between the CT’s should include a
!
terminal block for shorting the CT’s. Open CT secondaries will produce hazardous voltages, which can lead to personal injury or death, property damage, economic loss or CT failure.

General Operation
This chapter:

describes each function
defines operating parameters
Functional
The LSM has six different modes of operation. These modes are described below.
Configuration
Before the LSM can perform its intended functions, it must be configured by the integrator/OEM or user. Configuration is accomplished by sending the appropriate information to the module via the “Block Transfer Write” mechanism. Configuration data is compared with acceptable values. The user can obtain acknowledgment of the configuration data by using the “Block Transfer Read” mechanism for access to the module’s response. If out–of–range or illegal values were entered, an error indication that identifies the illegal or out–of–range entries is returned. If the data is acceptable, an acknowledgment indication is returned. The new configuration data is then used to scale the monitoring data and to set up the synchronization and load sharing functions.
Whenever new configuration data is sent to the LSM, all module functions (synchronization, load–sharing, and monitoring) are terminated, and the values for “Amps Demand”, “kVA Demand”, and “kW Demand” are cleared. The values for “kW Hours” and “kVAR Hours” are maintained at the values present before the new configuration data was sent. The new configuration data is then evaluated. Upon acceptance of the new configuration data, the module resumes normal operation.
A detailed description of the required configuration data follows. See “Block Transfer Communications”, on Page 4–2 in the Application Information chapter of this manual and Appendix B, “Block Transfer Tables and Discrete I/O Definition”, for a detailed description of how the module performs block transfers and how the associated data is organized.

This entry is used to indicate if the system being monitored is wired in a WYE, a Delta, or an open Delta. A value of “1” will indicate a WYE system, a value of “2” will indicate a three transformer Delta system, and a value of “4” will indicate a two transformer Open Delta system. Line–to–Neutral values will be provided only when a WYE is configured.

Maximum Synchronizing Bus Output Power
This entry is used to specify the power level at which the load sharing output voltage will be at its maximum value.

Number Of Demand Periods
This entry specifies the number of demand periods that should be averaged to determine the actual demand. The value must be between 1 and 15.
Synchronization
functionality of the synchronization process is based on the
The synchronization discrete outputs from the PLC–5 received via the PLC backplane. The “Initiate Synchronization” output from the PLC–5 begins the synchronization process when it is asserted. It must remain asserted during the entire process. If the initiate signal is removed, the synchronization process is terminated. In addition to the initiate signal, one of the “Auto–Synchronization”, “Check Synchronization”, or the “Permissive Synchronization” discrete outputs from the PLC–5 must be asserted. If more than one of those signals is present, the synchronization fails and the “Synchronization Failure” discrete input to the PLC–5 will be asserted.
Additional information pertaining to the cause of the failure may be obtained by reading the appropriate block transfer data from the “Synchronizing Bus Error Parameters” table. (See Appendix B, “Block T Definition”, for additional information.) If new setup information is received via block transfer while the LSM is in the Synchronization mode, synchronization is terminated. The new configuration data is evaluated and normal operation is resumed upon acceptance of the data.
ransfer and Discrete I/O
3–4
The “Auto–Synchronization” discrete output from the PLC–5 causes the LSM to issue the appropriate error signals, both continuous discrete inputs and via block transfer, to cause, via the PLC–5, the synchronizing bus voltage, frequency, and phase to align with the reference bus. Once these conditions are satisfied, the “Close Breaker” discrete input to the PLC–5 is asserted based on the synchronization configuration. In the event a “dead reference bus” condition exists, the “Synchronization Failure” discrete input to the PLC–5 is asserted. Additional information pertaining to the cause of the failure may be obtained by reading the appropriate block transfer data from the “Synchronizing Bus Error Parameters” table. (See Appendix B, “Block Transfer and Discrete I/O Definition”, for additional information.)
The “Check Synchronization” discrete output from the PLC–5 causes the LSM to function in the same manner as the “Auto–Synchronization” discrete output from the PLC–5 except it will not assert the “Close Breaker” discrete input to the PLC–5. This mode is useful for testing the system.

Synchronization Continued
The “Permissive Synchronization” discrete output from the PLC–5 prevents the LSM from issuing any error signals, but it asserts the “Close Breaker” discrete input to the PLC–5 if the synchronization criteria are satisfied. This mode also recognizes a “dead reference bus” condition and asserts the “Close Breaker” discrete input to the PLC–5 to allow an operator to bring the synchronizing bus on line when the reference bus has failed.
The “Enable Single Phase Synchronization” discrete output from the PLC-5 allows for single phase synchronization. In this mode, only the voltages applied to the V3 inputs of the synchronization bus and reference bus are used for synchronization. Any voltages applied to the V1 and/or V2 inputs are not used for synchronization purposes (i.e. phase rotation, dead-bus conditions and over-voltage conditions). Other than not using the V1 and V2 inputs, single phase synchronization does not change the operation of Auto, Check or Permissive synchronization functions.
Voltage Match Error = 100 (Reference Bus Voltage – Synchronizing
Bus Voltage) /(Reference Bus Voltage)
Frequency Match Error = (Reference Bus Frequency) – ( Synchronizing
Bus Frequency)
Phase Match Error = (Reference Bus Voltage Zero–cross Degrees) –
(Synchronizing Bus Voltage Zero–cross Degrees) [This calculation is performed on either both rising zero–crosses or both falling zero–crosses and the result is adjusted to provide a value between –180 degrees and +180 degrees.]
In the “Delayed Acceptance Window” method of synchronization, the “Close Breaker” discrete input to the PLC–5 is asserted after the “Voltage Match Error”, the “Frequency Match Error”, and the “Phase Match Error” have all remained continuously within their respective acceptance windows for the configured delay time, called: “Acceptance Window Delay”.
In the event the reference bus and synchronizing bus systems are opposite in phase rotation, the synchronization fails. This is indicated by the “Synchronization Failure” discrete input to the PLC–5. Additional information pertaining to the cause of the failure may be obtained by reading the appropriate block transfer data from the “Synchronizing Bus Error Parameters” table. (See Appendix B, “Block Transfer and Discrete I/O Definition”, for additional information.)
Important: While still indicated in single phase synchronization mode, phase rotation mismatch will not set the “synchronization failure” discrete input to the PLC-5.

Power Monitoring
In addition to the synchronization function, the LSM provides an extensive array of monitoring information. This data is accessible through one of several different block transfers. (See Appendix B, “Block Transfer Tables and Discrete I/O Definition”, for additional information.) All voltage and current measurements presented by the LSM are true RMS. The power measurements are calculated from the instantaneous voltage and current measurements. The remainder of the monitoring information is calculated from these values.
The LSM will clip the input voltages at approximately 1.25 times the maximum voltage input level. If this clipping takes place, the value 999 will be returned in every data field affected by the clipped channel.
The monitored values are scaled and reported based on the configuration entries that were provided by the user. This function is terminated if new configuration data is received. The new configuration data is evaluated and normal operation is resumed upon acceptance of the data. During synchronization those parameters not required for synchronization are monitored at a reduced priority. This allows critical synchronization data to be updated at a faster rate.

Load Sharing
The load sharing function allows multiple synchronizing buses to split the load requirements on a power system based on the relative capacity of each of the alternators. To use this function, the LSM must be configured with a “Maximum Alternator Output Power” entry, a “Load Share Full–Scale Voltage” entry, a “Load Share Deficit” entry, and a “Load Share Excess” entry. The first entry specifies the maximum desired power output for the alternator. The second entry specifies the load share output voltage that will be created when the alternator is operating at maximum power. The third and fourth entries define the regions where load sharing activity will take place. The region between these two entries is the dead–band where no corrective action takes place if the discrete inputs are being utilized for control. The full–scale voltage is configurable to be between 2 and 4 volts.
The load sharing function is enabled when the “Load Share Disable” discrete output from the PLC–5 is not asserted and the “Isochronous/Droop” discrete output from the PLC–5 indicates isochronous mode. If new setup information is received via block transfer while this function is enabled, load sharing is terminated. The new configuration data is evaluated and normal operation is resumed upon acceptance of the data.
The LSM provides a “Load Sharing Output” voltage that is resistively coupled to the dual function input/output terminals. The magnitude of the output voltage is calculated from the following formula:
(“Load Share Full–Scale Voltage”) (Actual Power) / (“Maximum Alternator Output Power”)
The “Load Sharing Input” voltage is measured from the dual function input/output terminals. The load sharing input is calculated by:
(“Load Sharing Input Voltage”) / (“Load Share Full–Scale Voltage”)
The “Load Share Error” is a fraction and is expressed as:
(Load Sharing Input Voltage) / (Load Share Full–Scale Voltage) – (Actual Power) / (Maximum Alternator Output Power)
If the error is negative, the alternator is supplying too much of the load requirements and the “Reduce Power – load share adjust” discrete input to the PLC–5 is asserted when the error exceeds the “Load Share Excess” entry. If the error is equal to zero, the load is being properly shared. If the error is positive, the alternator is not supplying enough of the load requirements and the “Raise Power – load share adjust” discrete input to the PLC–5 is asserted when the error exceeds the “Load Share Deficit” entry.
The LSM load sharing circuit is isolated from the external circuitry whenever load sharing is disabled, droop mode is indicated, or if power is removed from the module.

Control
The user can direct the LSM to perform several different functions by sending the appropriate block transfer data to the “Control Parameters Table”. (See Appendix B, “Block Transfer Tables and Discrete I/O Definition”, for additional information.) The functions that can be initiated are as follows:
Execute Self–Test (If the Execute Self–Test option is selected, no other
control options will be executed.)
Clear kW–HR Counter
Clear kVAR–HR Counter
Self–test
The LSM automatically performs a complete self–test every time the module is powered up or when commanded by an instruction embedded in the data sent via the control parameters block transfer write. The content of the data memory before the test is executed will be destroyed. However, the configuration parameters are maintained. If the self–test request is sent via the block transfer, it is performed once. The request must be repeated for additional tests. The self–test verifies the contents of the program memory, verifies performance of data memory, verifies the stored configuration data, checks the watchdog circuitry, and checks the performance of the analog input and analog output circuits to the extent possible.
3–8
A limited self–test that checks the validity of the stored configuration data and a limited test of the performance of the analog inputs is automatically performed at periodic intervals during normal operation.
Results of the self–test, either the full version or the limited version, are indicated in the module diagnostics available from the block transfer read data. (See Appendix B, “Block Transfer Tables and Discrete I/O Definition”, for additional information.) The diagnostic information that is available from the module is as follows:

Accuracy
The accuracy of the measurements and calculations made by the LSM are directly affected by the quality of the user supplied current and voltage transformers. Accuracy is affected by both the amplitude and phase errors introduced by the user supplied transformers. It is recommended that these transformers be Instrument Accuracy, Class 1 or better. The following accuracy values are relative to the signals that are present at the input terminals of the LSM.

The LSM exchanges data with the PLC backplane via both discrete I/O and block transfers. Due to the physical size of the module’s internal components, the LSM requires two slots in the I/O chassis. However, addressing assignments are made to the lower numbered slot of the two slots used.

Setup assistance for the LSM module is provided through the 6200 version
4.4 or later I/O Configuration Software. This configuration software contains the functionality to configure the module and to monitor the data produced by an operating module.
To make use of the configuration software, the ladder must exist with block transfer instructions programmed as shown in Appendix C. (See Sample Ladder listings in Appendix C) The BTR instructions must occur through the ladder to read data from the module. These are done through the use of the sequencer and the data table values to insure that only one block transfer is active at a given time.
This software also supports the setup of the Bulletin 1400 family of power monitoring equipment. More 6200 I/O Configuration Software information on the actual use of this tool is available in the 6200 Series software user’s manual.

Synchronization and Monitor with Load Share
In this mode of operation, data is returned for Synchronizing Bus voltage, current, and power values, and reference bus voltage values. The error values and discrete inputs to the PLC–5 for synchronization and load share are modified.
Block Transfer Communications
The LSM is capable of exchanging large amounts of data with the PLC processor via the Block Transfer mechanism. The amount of data greatly exceeds that which could be accommodated by a single block transfer. As a result, the data is divided into many different “files” and can be obtained through the use of multiple Block Transfers.
The LSM uses a unique scheme for differentiating between sets of parameters, or “files”, being written to or read from the module. The size of the block transfer operation is used to define the size of the transaction and is also used as a block type ID. Each of the “files” that the LSM recognizes has a unique size and can therefore be identified by the module. This is a very important aspect of understanding how the LSM communicates with the PLC–5. The size, structure, and content of the block transfer reads and writes supported by the LSM are provided in Appendix B.
ATTENTION: Only one block transfer at a time may be issued to the LSM. This means that until a BTR or BTW to the LSM has completed, another block transfer to the LSM must not be
!
initiated. Failure to observe this requirement will result in improper operation of the data exchange with the module.
Only one block transfer at a time may be issued to the LSM. This means that until a BTR or BTW to the LSM has completed, another block transfer to the LSM must not be initiated. Failure to observe this requirement will result in improper operation of the data exchange with the module.
The LSM uses a modulus method of accepting and returning numbers greater than 1000 or between 0 and 1. The modulus method splits these types of numbers into two or more words with the range 0– 999. The modulus is given in the form 10
For example, the number 10,000 would be represented by a 10 in the modulus 10 be represented by a 10 in the modulus 10

To process numbers to be sent to the LSM in this format, a number greater than 1,000 needs to be divided by 1,000 to obtain the modulus 10 This word must then be re–multiplied by 1,000 and subtracted from the original number to obtain the modulus 10
For example, the number 12,345 would be processed as follows:

Numbers such as 12.345 need to be processed as follows:

Configuration
The only method of configuring the LSM module is via the block transfer operation of the PLC–5. The data to be sent to the LSM must be stored in a data file of the PLC. There are two separate block transfer writes necessary to completely configure the LSM. The address of these data files must be used as the data file parameter of the BTW instruction with sizes of 35 and
12. Again, the correct sizes are necessary to identify to the LSM what type of data is being sent. The size, configuration, and contents of the block transfer tables accepted by the LSM are discussed in Appendix B.

and
The parameters sent to the LSM must be valid before the LSM will respond and begin normal operation. The validity of data sent to the LSM may be checked by requesting the Acknowledge Factory (or User) Configuration Parameters tables from the LSM. This is accomplished by initiating BTRs of size 25 or 15 from the LSM. The final non–reserved word of these tables is the overall configuration status of the previous configuration BTR. If this word is 0, the configuration succeeded and the LSM is running in one of the modes previously described. If this word is 4, one or more of the configuration parameters was out of range or illegal and all set up data is not accepted. Each word of the Acknowledge Configuration Parameters table should then be examined to determine which parameter was invalid.

Acquiring Data From the LSM
ed
The data from the LSM is returned in four tables. These tables are again differentiated by the size/ID of the BTR instruction. These tables are Synchronizing Bus Error Parameters, Synchronizing Bus Voltage/Current Parameters, Synchronizing Bus Power Parameters, and Reference Bus Voltage Parameters. The sizes and contents of these tables are provided in Appendix B of this document.
To acquire the table Synchronizing Bus Error Parameters from the LSM, the PLC–5 must issue a BTR instruction with the size of this table. The data file entry of the BTR is where the table from the LSM will be placed. Any operations using this data must then be directed to this file within the PLC–5.
Discrete Input / Output Control of the LSM
The LSM uses both discrete outputs from the PLC–5 and inputs to the PLC–5 in addition to its block transfer capabilities.

The Auto Synchronization Mode output from the PLC–5, Check Synchronization Mode output from the PLC–5, and the Permissive Synchronization Mode output from the PLC–5 are only used when the module is in a Synchronization mode (i.e. the Initiate Synchronization output from the PLC–5 is set). Only one of these Synchronization Mode outputs from the PLC–5 may be set at one time. If more than one of those signals is

present, the synchronization fails and the “Synchronization Failure” discrete input to the PLC–5 will be asserted. Additional information pertaining to the cause of the failure may be obtained by reading the appropriate block transfer data from the “Synchronizing Bus Error Parameters” table. (See Appendix B, “Block Transfer and Discrete I/O Definition”, for additional information.)
The Auto Synchronization Mode discrete output from the PLC–5 causes the LSM to issue the appropriate error signals, both continuous discrete inputs to the PLC–5 and via block–transfer, to cause via the PLC–5 the alternator voltage, frequency, and phase to align with the Reference Bus. Once these conditions are satisfied, the Close Breaker discrete input to the PLC–5 will be asserted based on the synchronization configuration.
The Check Synchronization Mode discrete output from the PLC–5 causes the LSM to function in the same manner as the Auto Synchronization Mode output from the PLC–5, except it will not assert the Close Breaker discrete input to the PLC–5. This mode is useful for testing the system.
The Permissive Synchronization discrete output from the PLC–5 will not cause the LSM to issue any error signals, but it will assert the Close Breaker discrete input to the PLC–5 if the synchronization criteria are satisfied.
The Load Share Disable discrete output from the PLC–5 when set to 1 will cause the load share function of the LSM to be disabled.
The Isochronous/Droop Mode discrete output from the PLC–5 when set to 1 indicates Isochronous mode of load share operation. If this output from the PLC–5 is cleared to 0 the LSM will operate in the droop mode of load share. While the LSM is in Droop mode, all load share errors and discrete inputs to the PLC–5 will be set to 0. The load share terminals on the front of the module will be disconnected from internal circuitry, therefore, the load share function is effectively disabled.
The Enable Single Phase Synchronization discrete output from the PLC-5, when set to 1, allows the synchronization function to ignore the V1 and V2 inputs. In this mode, phase rotation mismatch does not cause a synchronization failure, and the V1 and V2 inputs are not used for features such as dead-bus detect or over-voltage detection. This mode allows connection of the V3 inputs to single phase systems, or those systems with a single transformer per 3-phase system.

The Module Status discrete input to the PLC–5 when set to 1 indicates that the LSM has identified a potential problem. A value of 0 indicates normal operation of the LSM. Additional information pertaining to the cause of the problem may be obtained by reading the appropriate block transfer data from the “Diagnostic Parameters” Table B.11. (See Appendix B, “Block Transfer Tables and Discrete I/O Definition”, for additional information.)
If the Module Status discrete input to the PLC–5 is set to 1, all block transfer writes will be ignored and only the Diagnostic Parameters block transfer read will return valid data. Any other block transfers should not be executed at this time.
The Raise Voltage synchronization error discrete input to the PLC–5 indicates that the Synchronizing Bus has a lower voltage level than that of the Reference Bus.
The Lower Voltage synchronization error discrete input to the PLC–5 indicates that the Synchronizing Bus has a higher voltage level than that of the Reference Bus.
The Raise Speed – Frequency Adjust synchronization error discrete input to the PLC–5 indicates that the Synchronizing Bus is producing voltage at a frequency lower than that of the Reference Bus.

The Close Breaker discrete input to the PLC–5 indicates that all synchronization criteria have been met and it is acceptable to close the breaker between the Synchronizing Bus and the Reference Bus.
The Synchronization Failure discrete input to the PLC–5 indicates a synchronization error. When this bit is set, the LSM cannot perform Synchronizing Bus / Reference Bus synchronization.
When the Synchronization Failure discrete input to the PLC–5 is set, the Synchronization Status word in the Synchronizing Bus Error Parameters indicates the reason for synchronization failure.(See Appendix B Table B.6)
The Powered–up Bit discrete input to the PLC–5 indicates that the LSM has completed internal self– tests and is ready to perform block transfers with the PLC–5.
Included in Appendix B is a sample PLC–5 ladder program that interfaces with the LSM. The data files used are described in Tables 4.4 and 4.5.
ATTENTION: Executing the Control Request BTW from the sequencer file, or at a similar rate of speed could cause improper

operation of the LSM.

Data Files Used Continued
The following description applies to both files N21 and N22. The data at word 0 of N21 and N22: 1 must be the same. N2x:0 is the reset
word for the sequencer and N2x:1 is the first word in the rotation of the sequencer.
The data held in file N21 consists of the block transfer numbers needed to complete configuration in the order necessary to perform that task. This data must be as shown in the file N21 description for a sequencer size of 4. See Data File Table 4.5. The sequencer size may be altered, but no smaller than
4. If the size is expanded, the pattern of data in file N21 MUST be extended in the same fashion as it is shown below in the file N21 description.
The data held in file N22 consists of the block transfer numbers of the data desired in run mode. With the sequencer size set to 8, eight different block transfers may be executed sequentially. The numbers entered in file N22 may be altered to change the order of “run mode” block transfers being executed. The sample data as shown in the file N22 description ensures that the BTR for Synchronizing Bus Error Parameters occurs at regular intervals (i.e. 3 BTRs apart) and twice as frequently as any of the other block transfers. See Data File Table 4.5.
Note: Even though the block transfers may occur at a certain rate, the data they are transferring may not have been updated internally by the LSM. Changing the BT order in the sequencer may not significantly change the update rate of “new” data.
If more or different block transfers are desired, the sequencer size can be expanded and the files N21 and N22 MUST be expanded by the same amount.
Important: Failure to expand the data in files N21 and N22 will result in improper operation of the block transfer ladder, and possibly even a FAULT of the processor due to invalid indirect offsets. See Data File table 4–5.

Accessing BTR Data from PLC Ladder
To access a specific parameter from any of the BTRs, the BTR destination file must be known as well as the parameter number of the parameter desired. An illustration of this is an example taken directly from the Block Transfer Tables document and the example ladder diagram. (See Appendix B & C).
To obtain Synchronizing Bus Frequency in Hz from the Synchronizing Bus Voltage/Current Parameters BTR, the following words need to be read: N35:37 and N35:38.
Since the frequency is divided in 10 operations need to be performed to create a floating point representation of this number:
(N35:37
/1000)
+
N35:38 = frequency in floating point
For display purposes on a panel view terminal for example, it may not be necessary to perform this operation if the data can be divided into two fields and displayed as follows: N35:38. N35:37.
