3.6.1 SHUNT CONNECTION
ake care to ensure the correct polarity of the sensing wires, incorrect orientation will lead to negative
current readings. o test the orientation, run the generator and supply load. Ensure all current
readings are of correct polarity.
3.6.2 SHUNT ACCURACY
Ensure the correct shunts are chosen. For instance if the DSE module is providing overcurrent
protection, ensure the shunt is capable of measuring the overload level you wish to protect against,
and at the accuracy level you require without exceeding the maximum mV input.
For instance, this may mean fitting a larger shunt than required to measure overload currents which
will reduce the resolution of the reading.
he DSE module is accurate to better than 1% of the full-scale mV reading. o maintain this
accuracy you should fit accuracy class 0.5 or better.
You should check with your shunt manufacturer for further advice on selecting your shunts.

he 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. he level at which this
operates and whether this triggers a warning or shutdown alarm is configurable using the DSE
Configuration Suite Software.

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. he industry standard
communications interface (CAN) transports data gathered by the engine controller interface. his
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.

3.9.2 USB CONNECTION
he 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.
o connect a module to a PC by USB, the following items are required:
• DSE7450 Controller
• DSE Configuration Suite PC Software
(Supplied on configuration suite software CD or available from
www.deepseaplc.com).
• USB cable ype A to ype B.
( his 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 be connected to the module for configuration by PC.
NOTE: Refer to DSE7450 PC Configuration Suite Manual (DSE part 057 169) for further
details on configuring, monitoring and control.
3.9.3 USB HOST MASTER (USB DRIVE CONNECTION)
USB ype A connection for USB Host facility for USB storage device for data recording.
Maximum size of externally storage device is 16Gb (see viewing the instrument pages)

3.9.4 RS232
he RS232 port on the controller supports the Modbus R U protocol.
he Gencomm register table for the controller is available upon request from the DSE echnical
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.
Many PCs are not fitted with an internal RS232 serial port. DSE DOES NO recommend the use of
USB to RS232 convertors but can recommend PC add-ons to provide the computer with an RS232
port.

• For SMS only, a ‘normal’ voice SIM card is required. his 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 will enable the modem to answer an
incoming data call. Many ‘pay as you go’ services will not provide a CSD (Circuit Switched
Data) SIM card.

3.9.5 RS485
he RS485 port on the series controller supports the Modbus R U protocol.
he DSE Gencomm register table for the controller is available upon request from the DSE echnical
Support Department.
RS485 is used for point-to-point cable connection of more than one device (maximum 32 devices)
and allows for connection to PCs, PLCs and Building Management Systems (to name just a few
devices).
One advantage of the RS485 interface is the large distance specification (1.2km when using Belden
9841 (or equivalent) cable. his allows for a large distance between the module and a PC running the
DSE Configuration Suite software. he operator is then able to control the module, starting or
stopping the generator, selecting operating modes, etc.
he various operating parameters (such as output volts, oil pressure, etc.) of the remote generator
can be viewed or changed.
NOTE: For a single module to PC connection and distances up to 6m (8yds) the USB
connection method is more suitable and provides for a lower cost alternative to RS485 (which
is more suited to longer distance connections).
