WARNING
Read this entire manual and all other publications pertaining to the work to be performed before installing, operating or servicing this equipment. Practice all plant and safety instructions and precautions.
Failure to follow instructions can cause personal injury and/or property damage.
The engine, turbine or other type of prime mover should be equipped with an overspeed (overtemperature or overpressure, where applicable) shutdown device ( s), that operate s total ly independently of the
prime mover control device(s) to protect against runaway or damage to the engine, turbine or other
type of prime mover with possible personal injury or loss of life should the mechanical-hydraulic governor(s) or electric control(s), the actuator(s), fuel control(s), the driving mechanism(s), the linkage(s)
or the controlled device(s) fail.
Any unauthorized modifications to or use of this equipment outside its specified mechanical, electrical
or other operating limits may cause personal injury and/or property damage, including damage to the
equipment. Any such unauthorized modifications: (i) constitute "misuse" and/or "negligence" within
the meaning of the product warranty thereby excluding warranty coverage for any resulting damage
and (ii) invalidate product certifications or listings.
CAUTION
To prevent damage to a control system that uses an alternator or battery-charging device, make sure
the charging device is turned off before disconnecting the battery from the system.
Electronic controls contain static-sensitive parts. Observe the following precautions to prevent damage to these parts.
•
Discharge body static before handling the control (with power to the control turned off, contact a
grounded surface and maintain contact while handling the control).
•
Avoid all plastic, vinyl and Styrofoam (except antistatic versions) arou nd print ed circ uit boards.
•
Do not touch the components or conductors on a printed circuit board with your hands or with
conductive devices.

Application
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The Woodward DSLC-2
TM
control is the direct successor of the microprocessor-based DSLCTM synchronizer and
load control designed for use on three-phase AC generators. The DSLC-2
TM
control combines synchronizer, load
sensor, load control, dead bus closing system, var, power factor and process control, all integrated into one powerful package.
Applications allow up to 32 generators to be paralleled and controlled. A dedicated Ethernet system provides
seamless communications between DSLC-2
TM
and MSLC-2TM units. A second Ethernet port is provided for customer remote control and monitoring capability using Modbus TCP allowing DCS and PLC interfacing. Modbus
RTU is available through a separate RS-485 port.
DSLC-2 function summary
Original DSLC functions include:
• Selectable for phase matching or slip frequency synchronizing with voltage matching and automatic
dead bus closure capability
• Automatic generator loading and unloading for bumpless load transfer
• Droop, base load and isochronous load control capability
• Process control for cogeneration, import/export, pressure control or other processes
• Isochronous load sharing with other sets equipped with DSLC controls
• Var or power factor (PF) control
• Built in diagnostics
• Multifunction adjustable high and low limit alarms and load switch wit h re lay outputs
• Digital communications network to provide load sharing, var/PF sharing and other informatio n ex-
change between controls
• Reverse power relay
Additional DSLC-2 functions include:
• One dedicated Ethernet line for precise system communications between all DSLC-2’s and MSLC-2’s
on the system
• Ethernet Modbus/TCP for remote control and monitoring
• Serial Modbus RS-485 for remote control and monitoring
• Applications with up to 32 DSLC-2 and 16 MSLC-2
• Automatic segment control (self recognizing of the segment)
• Process control with up to 32 DSLC-2 or 1 Master MSLC-2
• Full setup, metering and diagnostic capability through the PC program ToolKit
Synchronizer
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Either phase matching or slip frequency synchronizing may be selected. Phase matching provides rapid synchronizing for critical standby power applications. Slip frequency synchronizing guarantees that initial power flow is
positive for all ge nerators. For both sync hronizing methods, the DSLC-2 control uses actual slip frequency and
breaker delay values to anticipate a minimum phase difference between bus and generator at actual breaker closure. The DSLC-2 control provides a safe automatic dead-bus closure function. Deadbus closing permission is
granted to only one DSLC-2 or MSLC-2 control in the whole system, through locking tech niques done over the
communications network. This assures that a race condition will not cause two or more breakers to close simultaneously on the dead bus. Additional synchronizer features include voltage matching, time delayed automatic multi-shot reclosing, auto-resynchronizing and a synchronizer timeout alarm. Each of these features may be enabled
or disabled during setu p.

Load Control
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Load control begins at breaker closure when the load control function takes control of the DSLC-2 speed bias
output dire ctly from the synchronizer. The matching of s ynchronizer s lip frequency to initial load (unload trip
level) can result in a bumpless transfer to load control. On command, the adjustable ramp allows smooth, timecontrolled loading into base load, isochronous load sharing or process control. A ramp pause switch input allows
holding of the load ramp for warm-up or other purposes. The base load control is an integrating controller. The
integrating base load control provides accurate load control when in parallel with a bus where frequency may
vary. The DSLC-2 control provides switch inputs to allow raising or lowering the internal digital base load reference. The control also provides an analog input for remote load setting.
When unloading, an adjustable unload ramp provides time controlled unloading to the unload trip level. When
load reaches the unload trip level, the control issues a breaker open command to separate the generator set from
the system. The ramp pause switch i nput is in effect while unloading to allow holding of the unload ramp for
cool-down or other purposes.
The load and unload ramps also provide smooth transition between base load, isochronous load sharing and
process control any time the operating mode is changed.
The DSLC-2 control includes several additional load control features:
• Load droop operation provides safe operation in parallel bus applications in the event of a circuit breaker
aux contact failure.
• A frequency trimmer function pr ovides accur ate frequency control in isochronous load sharing systems
by compensating for small varia tions in speed setting between units.
• Adjustable load switch output with independent pick-up and drop-out points provides a signal when the
specified load is exceeded. The load switch output can be selected as a reverse power trip.
• Load raise and lower inputs can be used to adjust speed before synchronizing.
• Voltage raise and lower inputs can be used to adjust voltage before synchronizing.
• A droop tr acking functi on is available automatically by a network fault or by a discrete input.

Process Control
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
A cascade PID process controller is provided for cogeneration, import/export control, pond level maintenance,
pressure maint e na nc e or other application. An adjustable bandwidth signal input filter, fle xible PID controller adjustments and control selectable for direct or indirect action, allow the process control to be used in a wide variety
of applications.
The analog i nput “Proc ess Signal Input” provides the real value for the DSLC-2 control. The control i ncludes an
internal digital process reference which may be controlled by raise and lower load switch contact inputs or by the
analog input “Process Signal”.
Adjustable ramps allow smooth entry to or exit from the process control mode. When the process control mode is
selected, an adjustable ramp moves the load reference in a direction to reduce the process control error. When the
error is minimized or the reference first reaches either the specified high or low load pick-up limits, the process
controller is activated. When a limit is reached, the control will hold the load r e fer e nce a t that limit until process
control is obtained.
When unloading from the process control, an adjustable unload ramp provides time controlled unloading to the
unload trip level. When load reaches the unload trip level, the DSLC-2 control automatically issues a breaker
open command to remove the generator set from the system. The ramp pause switch input allows holding of the
unload ramp for cool-down or other purposes.
Additional functions include s e le c ta ble and adjustable process high and low limit switches and alarm activation.
Var/PF Control
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The var/PF functions control the reactive power component of the generator in parallel systems. In an infinite bus
system, the controller compares either the kvar load or power factor (selectable) on the generator with an adjustable internal reference and makes corrections to the voltage regulator until the desired kvar load or power factor is
obtained. For higher performance, the “Voltage Bias” output, can be directly connected to compatible voltage
regulators with analog voltage setting input. The control has raise a nd lower voltage discrete inputs for manual
voltage adjustment. The control also has raise and lower contact outputs to activate a voltage regulator MOP
when an anal og input is not provided on the AVR.
The var/PF controller will limit the generators kvar output to the generator rated reactive power setpoi nt whe n
connected to an infinite bus. A DSL C-2 must be in baseload or process control or a MSLC-2 must be in control.
This will protect the generator when connected to an infinite source. This feature is not active when the DSLC-2
is in the load sharing mode (iso la te d).
The DSLC-2 control provides var sharing between multiple units when in an isolated bus application. The c ontrol
computes an average var value for the system and uses it as the reference input to the var controller. The control
includes an adjustable voltage reference and voltage trim function in the sharing function to maintain system voltage. The analog input “Reactive Load” is activated by closing both the voltage raise and lower discrete inputs.
This allows remote control of the PF reference setpoint when in power factor control. Each power factor setpoint
either external or internal is calculated to a var load setpoint. var load setpoints are r e str ic ted within the range -10
% to 100 % generator rated reactive power.
The DSLC-2 control has a selectable voltage range alarm which is activated if the analog output to the voltage
regulator r eaches high o r low saturat ion. The D SLC-2 control also has selectable and adjustable high and low
voltage limit switches and alar m outp uts.

DSLC-2 / MSLC-2 Systems
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The network a ddressin g of the DSLC-2 / MSLC-2 allows up to 32 DSLC-2s and 16 MSLC-2s in an application.
A DSLC-2 and MSLC-2 application can handle 8 segments. Discrete inputs inform the DSLC-2s and MSLC-2s
which segments each generator and utilities are operating on. If a MSLC-2 receives a discrete input to activate
segment 1 and 2, it will share this information with all controls over the Ethernet bus . It is not necessary to provide a segment activation discrete input to all controls. Segmenting allows the DSLC-2s and MSLC-2s to remain
connected thru the Ethernet bus, but be operating on separate load buses.
The DSLC-2 / M SLC-2 system can be applied according to following rules:
• The maximum number of DSLC-2s (Gen-CB) is 32.
• The maximum number of MSLC-2s (Utility- or Tie-CB) is 16.
• The maximum number of segments is 8.
• The segment numbers ha ve to follow a line, which can finally be closed to a ring.
• Only one MS LC-2 can be used as master control, when multiple MSLC-2 are resided in one segment.
o The MSLC-2 with the lower device number wi ll c ontrol if multiple Utility MSLC-2s are active
on the same segment
• The generator is not counted as a segment.
• The utility is not counted as a segment.
NOTE
If different MSLC-2s, located in different segments, are connected via a tie-MSLC-2, more than one
MSLC-2 is now located in the same segment. The result is the MSLC-2 with the lowest device number
becomes the master of all MSLC-2s located in this segment.

Installation
Electrostatic Discharge Awareness
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
All electronic equipment is static-sensitive, some components more than others. To protect these components
from static damage, you must take special precautions to minimize or eliminate electrostatic discharges.
Follow these precautions when working with or near the control.
Before doing maintenance on the electronic control, discharge the static electricity on your body to ground by
touching and holding a grounded metal object (pipes, cabinets, equi pment, etc.).
Avoid the build-up of static electricity on your body by not wearing clothing made of synthetic materials. Wear
cotton or cotton-blend materials as much as possible because these do not store static electric charges as
easily as synthetics.
Keep plastic, vinyl and Styrofoam materials (such as plastic or Styrofoam cups, cigarette packages, cellophane
wrappers, vinyl books or folders, plastic bottles, etc.) away from the control, modules and work area as
much as possible.
Opening the control cover may void the unit warranty.
Do not remove the printed circuit board (PCB) from the control cabinet unless absolutely necessary. If you
must remove the PCB from the control cabinet, follow these preca utio ns:
• Ensure that the device is completely voltage-free (all connectors have to be disconnected).
• Do not touch any part of the PCB except the edges.
• Do not touch the electrical conductors, connectors or components with conductive devices or with bare
hands.
• When replacing a PCB, keep the new PCB in the plastic antistatic protective bag it comes in u ntil you
are ready to install it. Immediately after removing the old PCB from the control c a binet, place it in the
antistatic protective bag.
CAUTION
To prevent damage to electronic components caused by improper handling, read and observe the precautions in Woodward manual 82715, Guide for Handling and Protection of Electronic Controls, Printed
Circuit Boards and Modules.
NOTE
The unit is capable to withstand an electrostatic powder coating process with a voltage of up to 85 kV
and a current of up to 40 µA.

Power Factor Definition
The phasor diagram is used from the generator's view. Power factor is defined as follows.
Power Factor is defined as a ratio of the real power to apparent power. In a purely resistive circuit, the voltage
and current waveforms are instep resulting in a ratio or power factor of 1.00 (often referred to as unity). In an inductive circuit the current lags behind the vo l tage waveform resulting in usable power (real power) and unusable
power (reactive power). This results in a positive ratio or lagging power factor (i.e. 0.85lagging). In a capacitive
circuit the current waveform leads the voltage waveform resulting in usable power (real power) and unusable
power (reactive power). This results in a negative ratio or a leading power factor (i.e. 0.85leading).
Inductive: Electrical load whose current waveform
lags the voltage waveform thus ha vi ng a laggin g power factor. Some inductive loads such as electric motors
have a large s t artup current requirement resul ting in
lagging power factors.
Capacitive: Electrical load whose current waveform
leads the voltage waveform thus having a leadi ng
power factor. Some capacitive loads such as capacitor
banks or buried cable result in leading power factors.

Page 40/226 © Woodward
Different power factor displa ys at the unit:
i0.91 (inductive)
lg.91 (lagging)
c0.93 (capacitive)
ld.93 (leading)
Reactive power display at the unit:
70 kvar (positive)
-60 kvar (negative)
Output at the interface:
+ (positive)
- (negative)
In relation to the voltage, the curr e nt is
lagging
leading
The generator is
over excited
under excited
Control: If the control unit is equipp e d with a power factor controller while in parallel with the utility:
A voltage lower "-" signa l is output as long as the
measured value is "more inductive" than the reference
setpoint
Example: measured = i0.91; setpoint = i0.95
A voltage raise "+" signal is output as long as the
measured value is "more capacitive" than the reference setpoint
Example: measured = c0.91; setpoint = c0.95

Discrete Inputs: Signal Polarity
The discrete inputs are electrica lly isolated which permits the po la rity of the connections to be either positive or
negative.
NOTE
All discrete inputs must use the same polarity, either positive or negative signals, due to the common
ground.

CAUTION
The discrete output "Alarm (Self Test OK)" can be wired i n series with an emerg ency stop function.
This means that it must be ensured that the generator circuit breaker can be opened, if this discrete
output is de-energized. We recommend to signal this fault independently from the unit if the availability
of the plant is important.
NOTE
The relay output [R 05] “Breaker Open” opens the breaker by opening the contacts. The contacts are
closed if the generator voltage and frequency are in operating range and no open command is active.

Slip frequency: The synchronizer adjusts the generator frequen-
cy to a point greater than the busbar. The slip frequency is determined by the s etting of Slip frequency setpoint offset (parameter
5502). The generator will always close to the bus at a higher frequency, eliminating the possibility of reverse power.

gle of the generator to that of the busbar.

The setpoint for the frequency trim is the system rated frequency
(parameter 1750). When in isochronous or load sharing mode, increasing the proportional gain, increases the sensitivity to the error between the system frequency and the desired frequency (parameter 1750). If the gain is configured too high, the result is
excessive overshoot/undershoot of the desired value. Remember
the frequency trim PID is active during load sharing. Setting the
proportional gain to high may cause instability with the load sharing function.

The integral gain corrects for any offset between the system rated
frequency (parameter 1750) and the actual system frequency. If
the integral gain constant is too large, the engine will continually
oscillate. If the integral gain constant is too small, the engine will
take too long to settle. Remember the frequency trim PID is active
during load sharing. Setting the integral gain to high may cause
instability with the load sharing function.
NOTE: The integral gain constant must be greater than the de-
rivative time constant. Not active during synchronization.

controlled in such a manner that the measured voltage does not
deviate from the monitored reference bus voltage by more than
the value configured in this parameter without the controller issuing a voltage raise/lower signal to the voltage regulator. The

General
NOTE
Beside the generator 3-phase measurement the DSLC-2 provides a busbar 1-phase measurements and
an auxiliary busbar 3-phase measurement. The busbar 1-phase measurement at the terminals 37-40
has to be connected in each application. The auxiliary busbar 3-phase AC measurement at the terminals 21-28 can additionally be used. When both measurements are used the busbar voltage has to be
connected to both inputs. With the parallel use of the auxiliary busbar measurement, the DSLC-2 can
determine correct vo ltages on all 3 phases on the bus and becomes part of the operating range- and
the phase rotation monitoring.

Password System
The DSLC-2 utilizes a password protected multi-le vel configuration access hierarchy. This permits varying degrees of access to the parameters being granted by assigning unique passwords to designated personnel. A distinction is made between the access levels as follows:
Code level CL0 (User Level) Standard password = none
This code level permits for monitoring of the system and limited access to the parameters. Configuration of the
control is not permitted. The unit powers up in this co de level.
Code level CL1 (Service Level) Standard password = "
0 0 0 1"
This code level entitles the user to change selected non-critical parameters. The user may also change the password for level CL1. Access granted b y this password expires two hours after the password has been entered and
the user is returned to the CL0 level.
Page 87
Manual 37443A DSLC-2 - Digital Synchronizer and Load Control
© Woodward Page 87/226
Code level CL2 (Temporary Commissi on i n g Level ) No standard password available
This code level grants temporary access to most of the parameters. The password is calculated from the random
number generated when the password is initially accessed. I t is designed to grant a user a one-time access to a parameter without having to provide a r eusable password. The user may also change the password for level CL1.
Access granted by this password expires two hours after the password has been entered and the us er is returned to
the CL0 level. The password for the temporary commissioning level may be obtained from the vendor.
Code level CL3 (Commissioning Level) Standard password = "
0 0 0 3"
This code level grants complete and total access to most of the parameters. In addition, the us er may also change
the passwords for levels CL1, CL2 and CL3. Access granted by this password expires two hours after the password has been entered and the user is returned to the CL0 level.
NOTE
Once the code level is entered, access to the configuration menus will be permitted for two hours or
until another password is entered into the control. If a user needs to exit a code level, the user would
enter “Details” and select “Log Off”. This will block unauth orized confi guration of the control. A user
may return to CL0 by allowing the entered password to expire after two hours or by changing any one
digit on the random number generated on the password screen and entering it into the unit.
It is possible to disable expiration of the password by entering "0000" after the CL1 or CL3 password
has been entered. Access to the entered code level will remain enabled until another password is entered. Otherwise, the code level would expire when loading the standard values (default 0000) via
ToolKit.

Off
Off: An analog signal is selected.
On: A PWM signal will be supplied on the voltage bias output.
This is a voltage signal, so the hardware output must have a jumper between terminals 18 and 19. The amplitude of the PWM signal to be utilized is configured in PWM output level (parameter
5224). The PWM signal will also be limited by parameter 5215 or
5222 and parameter 5223 if parameter 5215 is user defined.

voltage bias output functions from 0 to a 100 %.
Example:
Selected Hardware type (parameter 5251) of +/-3 V
• A setting of 50 % will provide a 0 V output.
• A setting of 25 % will provide a -1.5 V output
•
A setting of 75 % will provide a +1.5 V output

Menu 7 – Electrical Parameters
This menu contains the electrical parameters of the DSLC-2.
Figure 3-31: ToolKit – electrical parameters
Menu 7 provides all the AC measurement, volta ge, c urr ent , p ower and reactive power. The generator is always a
3-phase measurement and the busbar is mea s ured as a single phase. A configuration in Menu 5, Auxiliary busbar
available (parameter 7629), allows additionally the measurement of the busbar with 3 phases. The option of the
3-phase busbar measurement allows the monitoring of all 3 p hases and detection of the busbars phase rotation.
Menu 7 will display the auxiliary busbar measurement values when parameter 7629 is configured to“Yes”.
