WARNING

Read this entire manual and all other publications pertaining to the work to be performed before in-

stalling, operating, or servicing this equipment. Practice all plant and safety instructions and precau-

tions. 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 (overtempera-

ture, or overpressure, where applicable) shutdown device(s), that operates totally 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 gov-

ernor(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 dam-

age 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) around printed circuit boards.

Do not touch the components or conductors on a printed circuit board with your hands or with con-

ductive devices.

Changes

2016-09-08

New features related to new software version 1.1504 or higher

Added a 2 seconds delay time to the missing member 7594 alarm to compensate time

delays from other/external Ethernet members.

Manual

Describes installation of latest ToolKit version on page 50 ff

2016-04-27

New features related to new software version 1.1503 or higher

The IP address of network A is configurable.

Ethernet channels A and B can be Enabled or Disabled in ToolKit. Items 7860 controls

network A and 7861 controls network B. These items are found in Menu 5.1 –Interfaces

In a Ring Structured application, the MSLC-2 Tie breaker control that connects segment

8 to segment 1, must have item 4544, “Basic segment number”, set for 8. The System A

PT will connect on the segment 8 side of the breaker while the System B PT will connect

to the segment 1 side. The PT connections are opposite all other Tie mode MSLC-2s in

the system.

Utility Unload function operates correctly in a Utility mode control with all segment break-

ers closed.

Synchronizer menu (Menu 1 –Synchronizer), added items 4717, “Phase window ring

structure”, and 4718, “Voltage window ring structure”, to use when attempting to close the

last segment in a ring bus application. There is no active synchronization done when at-

tempting to close the last tie breaker in a ring bus application.

Utility Unload with all 8 segments closed: In case of a closed ring, a check in TIE MSLC2

was added, for direct open the breaker if all segments are closed. For Utility MSLC2 Un-

loading is done therefore. Refer to chapter “Special Function - Synchronizing the last

breaker in a ring structure” for details.

ToolKit

Use version 5.0.2 or higher

Corrections

Modbus address 50082 for reading Discrete Inputs DI22 “Modbus reset”, and DI23 “Sys-

tem Update”are now available. (Appendix C –Data Protocols –Digital Inputs 2)

(2014-01-15)

New features with software revision 1.15xx or higher

Redundant Ethernet with communication handling for Network A and Network B is imple-

mented. Refer to Menu 5.1 –Interfaces on page 90 for details and further description on

page 176ff.

System update function added (parameter 7789, page 86).

Modbus slave (device) parameter Network A (parameter 5351) / Network B (parameter

5451) adjustable in the range from 0 to 255 (page 93).

Now, the Network B-UDP/Modbus IP_Addr is full adjustable

(see Menu 5.1 –Interfaces, page 91).

The closing of the last Breaker in a ring structure is now configurable with extended

ranges of phase angle (parameter 4717 Phase window in ring structure) and voltage win-

dow (parameter 4718 Voltage window ring structure).

Refer to Menu 1 –Synchronizer/

Synchronizer Control on page 67 for details.

Phase angle compensation MCB (parameter 8841) added by a tunable for a phase angle

deviation (parameter 8842) in the range of +/- 180.0°.

CB close hold time (parameter 3417) with extended setting range (page 67).

In case of Utility Unload, the load is ramped to the Unload trip level with the Unload ramp

rate.

The fixed frequency and voltage ramp rates of the digital potentiometers are replaced by

configurable ramp rates (%rated/s) for Frequency- and Voltage- Raise/Lower.

f: DI raise/lower frequency parameter 4713/ 4714; see page 67

V: DI voltage raise/lower parameter 4715/4716; see page 76

Changes

Manually synchronization within Permissive Synchronizer mode possible now.

Extended range of power factor: Power factor reference parameter 5620 configurable be-

tween - 0.5 and 0.5. Refer to Menu 4 –Voltage/Var/PF Control/Var Control on page 78

for details.

A new Lamp Test function for LEDs on housing is provided.

Connection plausibility check: System B not connected but Auxiliary Busbar connected,

will lead to the Alarm "System B mismatch" (parameter 7770).

Refer to NOTE at page 35 for details.

New energy counters implemented (see Menu 5.3 and Menu 8 on pages 96/109):

System A pos./neg. active energy counter (kWh,

parameters 2510&2520/2512&2524)

System A pos./neg. reactive energy counter (kvarh,

parameters 2511&2522/2513&2526)

Further setpoints are made adjustable via interface by source selection:

Frequency control setpoint source (parameter 7783, page 66)

Voltage control setpoint source (parameter 7784, page 76)

Monitoring GAP via Ethernet is possible (Woodward service, only!).

The Basic segment number can be set in addition via Interface (Basic segment number

source parameter 7786, page 84)

New segmenting mode: Well-known bus segmenting now is enhanced for device seg-

menting. Refer to New segmenting mode: Well-known bus segmenting now is enhanced

for device segmenting. Refer to page 169 for details.

Data telegram 5200 updated according to the new features.

Refer to Data Protocol 5200 on page 201 for details.

Set minimum values of IDs 10411..10415 from 0000 to 0001 (page 94).

Number of DSLC communicating (4708) and Number of MSLC communicating (parame-

ter 4707) deleted.

ToolKit

New version 4.5 available. Description updated (page 50).

Revision of several menus with additional headers for better overview.

The number of the connected Device is displayed on each menu page heading.

LED for Phase rotation mismatch alarm is displayed on the Home page.

ToolKit connection via Ethernet is now implemented for the connection of multiple de-

vices. One of maximum 16 MSLC can be selected in Tool Device (page 55).

Synchronizer mode (parameter 4602) in ToolKit display extended with “Manual” for man-

ual synchronizer function (see ToolKit homepage, page 61 and Menu 8, page 107).

Overview screens for DSLC-2 and MSLC-2 modified for redundant Ethernet with addi-

tional LED and text for each Unit ID (page 115ff). For description see page 176ff.

Additional alarms (see Menu 8 –Control Status Monitor/

Alarms, page 108):

Connection plausibility check System B mismatch (parameter 7770)

Phase rotation mismatch (parameter 7777)

Communication error NW A (parameter 4615),

Communication error NW B (parameter 7787)

transfer.

Improved tie-breaker unloading function with bumpless transfer, when the connected util-

ity MSLC has a closed breaker.
