1 INTRODUCTION
This document details the installation and operation requirements of the DSE8660 MKII module and is
part of the DSEGenset® range of products.
The manual forms part of the product and should be kept for the entire life of the product. If the
product is passed or supplied to another party, ensure that this document is passed to them for
reference purposes.
This is not a controlled document. DSE do not automatically inform on updates. Any future updates of
this document are included on the DSE website at www.deepseaplc.com
The DSE86xx MKII series is designed to provide differing levels of functionality across a common
platform. This allows the generator OEM greater flexibility in the choice of controller to use for a
specific application.
The DSE8660 MKII module is designed to provide differing levels of functionality across a common
platform. This allows the generator OEM greater flexibility in the choice of controller to use for a
specific application.
Synchronsing and Load Sharing features are included within the controller, along with the necessary
protections for such a system.
The user also has the facility to view the system operating parameters via the text LCD display.
The DSE8660 MKII module has been designed to monitor the mains (utility) supply and automatically
start/stop one or more generator sets equipped with DSE8610 MKII controllers depending upon the
status of the mains (utility) supply.
The powerful ARM microprocessor contained within the module allows for incorporation of a range of
complex features:
Text based LCD display
True RMS Voltage
Current and Power monitoring
USB, RS232, RS485 and Ethernet Communications
Fully configurable inputs for use as alarms or a range of different functions.
Synchronising and load sharing with load demand start/stop
Integral PLC to help provide customisation where required
Data Logging
R.O.C.O.F. and vector shift protection for detection of mains failure when in parallel with the mains.
The DSE Configuration Suite PC Software allows alteration of selected operational sequences,
timers, alarms and operational sequences. Additionally, the module’s integral front panel configuration
editor allows adjustment of this information.
Access to critical operational sequences and timers for use by qualified engineers, can be protected
by a security code. Module access can also be protected by PIN code. Selected parameters can be
changed from the module’s front panel.
The module is housed in a robust plastic case suitable for panel mounting. Connections to the module
are via locking plug and sockets.

2.6.1 VA RATING OF THE CTS
NOTE: Details for 4 mm² cables are shown for reference only. The connectors on the DSE
modules are only suitable for cables up to 2.5 mm².
The VA burden of the module on the CTs is 0.5 VA. However depending upon the type and length of
cabling between the CTs and the module, CTs with a greater VA rating than the module are required.
The distance between the CTs and the
measuring module should be
estimated and cross-referenced
against the chart opposite to find the
VA burden of the cable itself.
If the CTs are fitted within the
alternator top box, the star point
(common) of the CTs should be
connected to system ground (earth) as
close as possible to the CTs. This
minimises the length of cable used to
connect the CTs to the DSE module.
Example:
If 1.5 mm² cable is used and the
distance from the CT to the measuring
module is 20 m, then the burden of the
cable alone is approximately 15 VA.
As the burden of the DSE controller is
.5 VA, then a CT with a rating of at
least 15 VA + 0.5 VA = 15.5 VA must
be used. 0.5 VA, then a CT with a rating of at least 15 VA + 0.5 VA = 15.5 VA must be used. If 2.5
mm² cables are used over the same distance of 20 m, then the burden of the cable on the CT is
approximately 7 VA. CT’s required in this instance is at least 7.5 VA (7 + 0.5).

2.6.2 CT POLARITY
NOTE: Take care to ensure correct polarity of the CT primary as shown above. If in doubt,
check with the CT supplier.
Take care to ensure the correct polarity of the CTs. Incorrect CT orientation leads to negative kW
readings when the set is supplying power. Take note that paper stick-on labels on CTs that show the
orientation are often incorrectly placed on the CT. It is more reliable to use the labelling in the case
moulding as an indicator to orientation (if available).
To test orientation, run the generator in island mode (not in parallel with any other supply) and load
the generator to around 10 % of the set rating. Ensure the DSE module shows positive kW for all
three individual phase readings.

Polarity of CT Primary
2.6.3 CT PHASING
Take particular care that the CTs are connected to the correct phases. For instance, ensure that the
CT on phase 1 is connected to the terminal on the DSE module intended for connection to the CT for
phase 1.
Additionally ensure that the voltage sensing for phase 1 is actually connected to generator phase 1.
Incorrect connection of the phases as described above results in incorrect power factor (pf)
measurements, which in turn results in incorrect kW measurements.
One way to check for this is to make use of a single-phase load. Place the load on each phase in turn,
run the generator and ensure the kW value appears in the correct phase. For instance if the load is
connected to phase 3, ensure the kW figure appears in phase 3 display and not in the display for
phase 1 or 2.
2.6.4 CT CLASS
Ensure the correct CT type is chosen. For instance if the DSE module is providing over current
protection, ensure the CT is capable of measuring the overload level required to protect against, and
at the accuracy level required.
For instance, this may mean fitting a protection class CT (P15 type) to maintain high accuracy while
the CT is measuring overload currents.
Conversely, if the DSE module is using the CT for instrumentation only (current protection is disabled
or not fitted to the controller), then measurement class CTs can be used. Again, bear in mind the
accuracy required. The DSE module is accurate to better than 1% of the full-scale current reading. To
maintain this accuracy, fit a Class 0.5 or Class 1 CT.
Check with the CT manufacturer for further advice on selecting CTs.

2.10 COMMUNICATION PORT USAGE
2.10.1 USB SLAVE PORT (PC CONFIGURATION)
NOTE: DSE stock 2 m (6.5 feet) USB type A to type B cable, DSE Part Number: 016-125.
Alternatively they are purchased from any PC or IT store.
NOTE: The DC supply must be connected to the module for configuration by PC.
NOTE: For further details of module configuration, refer to DSE Publication: 057-257
DSE8660 MKII Configuration Suite PC Software Manual.
The USB port is provided to give a simple means of connection between a PC and the controller.
Using the DSE Configuration Suite Software, the operator is then able to control the module, starting
or stopping the engine, selecting operating modes, etc.
Additionally, the various operating parameters (such as coolant temperature, oil pressure, etc.) of the
engine are available to be viewed or changed.
To connect a module to a PC by USB, the following items are required:
DSE86xx MKII Controller
DSE Configuration Suite PC Software
(Supplied on configuration suite software CD or available from
www.deepseaplc.com).
2.10.1.1 USB HOST PORT (USB STORAGE DEVICE CONNECTION)
USB Type A connection for an of external USB storage device of maximum 16 GB for instrumentation
data logging.

2.10.2 RS232 PORT
NOTE: For direct connection an RS232 null modem (crossover) cable is required. This is
rated to a maximum cable length of 15 m.
NOTE: For a single module to PC connection and distances up to 6 m (20 feet) the USB
connection method is more suitable and provides for a lower cost alternative to RS485 (which
is more suited to longer distance connections).
The RS232 port on the controller supports the MODBUS RTU protocol and is for connection to a
single MODBUS master device only.
The MODBUS register table for the controller is available upon request from the DSE Technical
Support Department.
RS232 is for short distance communication (max 15m) and is typically used to connect the controller
to a telephone or GSM modem for more remote communications.
The various operating parameters (such as coolant temperature, oil pressure, etc.) of the remote
engine are viewed or changed.
Many PCs are not fitted with an internal RS232 serial port. DSE DOES NOT recommend the use of
USB to RS232 convertors but can recommend PC add-ons to provide the computer with an RS232
port.
2.10.2.1 RECOMMENDED EXTERNAL MODEMS
NOTE: For GSM modems a SIM card is required, supplied by the GSM network provider:
For SMS only, a ‘normal’ voice SIM card is required. This enables the controller to send SMS
messages to designated mobile phones upon status and alarm conditions.
For a data connection to a PC running DSE Configuration Suite Software, a ‘special’ CSD
(Circuit Switched Data) SIM card is required that enables the modem to answer an incoming
data call. Many ‘pay as you go’ services do not provide a CSD (Circuit Switched Data) SIM
card.
