2 INTRODUCTION
This document details the installation and operation requirements of the DSE8800 Series modules,
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. You will not be automatically informed of updates. Any future
updates of this document will be included on the DSE website at www.deepseaplc.com
The DSE8800 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 DSE8810 controller has been designed to allow the operator to start and stop the generator, and
if required, transfer the load to the generator either manually (via fascia mounted push-buttons) or
automatically. Additionally, the DSE8860 automatically starts and stops the generator set depending
upon the status of the mains (utility) supply.
The user also has the facility to view the system operating parameters via the LCD display.
The DSE8800 module monitors the engine, indicating the operational status and fault conditions,
automatically shutting down the engine and giving a true first up fault condition of an engine failure by
a COMMON AUDIBLE ALARM. The LCD display indicates the fault.
The powerful ARM microprocessor contained within the module allows for incorporation of a range of
complex features:
•Text and graphical colour LCD display (supporting multiple languages).
•True RMS Voltage, Current and Power monitoring with minimum and maximum holt
•Harmonic Display
•Communications capability (RS485, RS232 and Ethernet)
•Engine parameter monitoring.
•Event log and instrumentation data log
•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
•Fuel tank level monitoring to track fuel filling operations and detect fuel leak/theft
•Engine ECU interface to electronic engines.
Using a PC and the DSE Configuration Suite software allows alteration of selected operational
sequences, timers, alarms and operational sequences. Additionally, the module’s integral fascia
configuration editor allows adjustment of a subset of this information.
A robust plastic case designed for front panel mounting houses the module. Connections are via
locking plug and sockets..
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.

Accuracy ±1 % of Nominal (1 A or 5 A) (excluding CT error)
3.5.1 VA RATING OF THE CTS
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
0.5 VA, then a CT with a rating of at
least 15+0.5 V = 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).
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.
NOTE: - CTs with 5 A secondary windings are recommended with DSE modules. 1 A CTs
can be used if necessary however, the resolution of the readings is 5 times better when using
5 A CTs.

3.5.2 CT POLARITY
Take care to ensure the correct polarity of the CTs. Incorrect CT orientation will lead 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.
TO GENERATOR
TO LOAD SWITCH DEVICE
POLARITY OF CT PRIMARY
NOTE:- Take care to ensure correct polarity of the CT primary as shown above. If in
doubt, check with the CT supplier.
3.5.3 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 will result 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.
3.5.4 CT CLASS
Ensure the correct CT type is chosen. For instance if the DSE module is providing overcurrent
protection, ensure the CT is capable of measuring the overload level you wish to protect against, and
at the accuracy level you require.
For instance, this may mean fitting a protection class CT (P10 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 you require. The DSE module is accurate to better than 1% of the full-scale current reading.
To maintain this accuracy you should fit Class 0.5 or Class 1 CTs.
You should check with your CT manufacturer for further advice on selecting your CTs
labelled as p1,
k or K
labelled as p2,
l or L

3.6.5 CHARGE FAIL INPUT
Minimum voltage 0V
Maximum voltage 35V (plant supply)
Resolution 0.2V
Accuracy ± 1% of max measured voltage
Excitation Active circuit constant power output
Output Power 2.5W Nominal @12V and 24V

Current at 24V 105mA
The charge fail input is actually a combined input and output. Whenever the generator is required to
run, the terminal provides excitation current to the charge alternator field winding.
When the charge alternator is correctly charging the battery, the voltage of the terminal is close to the
plant battery supply voltage. In a failed charge situation, the voltage of this terminal is pulled down to
a low voltage. It is this drop in voltage that triggers the charge failure alarm. The level at which this
operates and whether this triggers a warning or shutdown alarm is configurable using the DSE Config
Suite Software.

NOTE : DSE can supply a suitable magnetic pickup device, available in two body thread
lengths :
DSE Part number 020-012 - Magnetic Pickup probe 5/8 UNF 2½” thread length
DSE Part number 020-013 - Magnetic Pickup probe 5/8 UNF 4” thread length
Magnetic Pickup devices can often be ‘shared’ between two or more devices. For example, one
device can often supply the signal to both the module and the engine governor. The possibility of this
depends upon the amount of current that the magnetic pickup can supply.

3.9 COMMUNICATION PORT USAGE
3.9.1 CAN INTERFACE
Modules are fitted with the CAN interface as standard and are capable of
receiving engine data from engine CAN controllers compliant with the
CAN standard.
CAN enabled engine controllers monitor the engine’s operating
parameters such as engine speed, oil pressure, engine temperature
(among others) in order to closely monitor and control the engine. The industry standard
communications interface (CAN) transports data gathered by the engine controller interface. This
allows generator controllers to access these engine parameters with no physical connection to the
sensor device.
NOTE:- For further details for connections to CAN enabled engines and the functions
available with each engine type, refer to the manual Electronic Engines and DSE Wiring.
