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)
• Synchronization Status
— Frequency Within Limits
— Voltage Within Limits
— Phase Within Limits
— Synchronization Mode Conflict Failure
— Phase Rotation Mismatch Failure (3 phase synchronization mode only)
— No Reference Bus Voltage Present Failure
— No Synchronizing Bus Voltage Present Failure
— Reference Bus Over Voltage Failure
— Synchronizing Bus Over Voltage Failure

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.

Installation
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
2
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.
2–3
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:
• introduces the user to the controls and operation
• 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.

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.

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

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:
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.

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.

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

Upon successful configuration, or on power up with a previously configured
module, the LSM will be in one of the following modes:
• Monitor Only

• Synchronization and Monitor
• Synchronization and Monitor with Load Share

Synchronization and Monitor with Load Share
In this mode of operation, data is returned for Synchronizing Bus voltage,

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

To process numbers to be sent to the LSM in this format, a number greater

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.

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.

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.

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.
