2 INTRODUCTION
This document details the installation and operation requirements of the DSE4610 & DSE4620
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 docu ent. 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 DSE4xxx 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 DSE46xx series module has been designed to allow the operator to start and stop the generator,
and if required, transfer the load to the generator either manually or automatically. Additionally, the
DSE4620 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 DSE46xx 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 the LCD display.
The powerful A M microprocessor contained within the module allows for incorporation of a range of
complex features:
• Icon based LCD display
• True RMS Voltage
• Current and Power onitoring (Not applicable to the DSE46xx-01 variant)
• USB Co unications
• Engine para eter onitoring.
• Fully configurable inputs for use as alar s or a range of different functions.
• Magnetic Pickup Interface for engine speed easure ent (optional).
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 front panel
configuration editor allows adjustment 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.

3.7.1 VA RATING OF THE CTS
The VA burden of the module on the CTs is 0.5VA. 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 1.5mm² cable is used and the
distance from the CT to the measuring
module is 20m, then the burden of the
cable alone is approximately 15VA. As
the burden of the DSE controller is
0.5VA, then a CT with a rating of at
least 15+0.5V = 15.5VA must be used.
If 2.5mm² cables are used over the
same distance of 20m, then the
burden of the cable on the CT is
approximately 7VA. CT’s required in
this instance is at least 7.5VA (7+0.5).
NOTE: Details for 4mm² ca les are shown for reference only. The connectors on the DSE
modules are only suita le for ca les up to 2.5mm².

3.7.2 CT POLARITY
NOTE: Take care to ensure correct polarity of the CT primary as shown a ove. If in dou t,
check with the CT supplier.
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 LOAD
POLA ITY OF CT P IMA Y
3.7.3 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.
3.7.4 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

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 Configuration Suite Software.

3.10 USB PORT
USB Port USB 2.0 Device for connection to PC running DSE configuration suite only.
Max distance 6m (18 yards)
3.10.1 USB PORT USAGE
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 generator, selecting operating modes, etc.
Additionally, the various operating parameters (such as output volts, oil pressure, etc.) of the remote
generator are available to be viewed or changed.
To connect a module to a PC by USB, the following items are required:
• DSE46xx Controller
• DSE Configuration Suite PC Software
(Supplied on configuration suite software CD or available from
www.deepseaplc.com).
• USB cable Type A to Type B.
(This is the same cable as often used between a PC and a USB
printer)
DSE can supply this cable if required :
PC Configuration interface lead (USB type A – type B) DSE
Part No 016-125
NOTE: The DC supply must e connected to the module for configuration y PC.

3.11 ADDING AN EXTERNAL SOUNDER
Should an external alarm or indicator be required, this can be achieved by using the DSE
Configuration Suite PC software to configure an auxiliary output for “Audible Alarm”, and by
configuring an auxiliary input for “Alarm Mute” (if required).
The audible alarm output activates and de-activates at the same time as the module’s internal
sounder. The Alarm mute input and internal alarm mute button activate ‘in parallel’ with each other.
Either signal will mute both the internal sounder and audible alarm output.
Example of configuration to achieve external sounder with external alarm mute button:

3.13.4 FIXING CLIPS
The module is held into the panel fascia using the supplied fixing clips.
• Withdraw the fixing clip screw (turn anticlockwise) until only the pointed end is protruding
from the clip.
• Insert the three ‘prongs’ of the fixing clip into the slots in the side of the module case.
• Pull the fixing clip backwards (towards the back of the module) ensuring all three prongs of
the clip are inside their allotted slots.
• Turn the fixing clip screws clockwise until they make contact with the panel fascia.
• Turn the screws a little more to secure the module into the panel fascia. Care should be
taken not to over tighten the fixing clip screws.
