Introduction

2 INTRODUCTION

This document details the installation and operation requirements of the DSE7400 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 DSE7400 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 DSE7400 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 (via fascia mounted push-buttons) or automatically. Additionally, the DSE7420 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 DSE7400 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 based LCD display (supporting multiple languages).

• True RMS Voltage, Current and Power monitoring.

• Communications capability (RS485, RS232 or Ethernet)

• Engine parameter monitoring.

• Fully configurable inputs for use as alarms or a range of different functions.

• 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.

3.5.1 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).

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.

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

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.

3.7.2.1 CONTACTOR COILS

Use output D, the normally open relay:

Generator

DSE output drives the contactor coil, via external slave relay if required. When the DSE module requires the contactor closed, the output energises (closing the internal relay) When the DSE module requires the contactor to be open, the output is de-energised (opening the internal relay)

3.7.2.2 UNDERVOLTAGE (UV COILS)

Use output C, the normally closed relay :

Generator

DSE output drives the UV coil, via external slave relay if required. When the generator starts, the UV is powered via the normally closed relay. The breaker is now ready for the close signal to be given. When the breaker is to be opened, the Open Generator Pulse relay is operated, removing power from the UV coil for one second. This causes the breaker to trip (open) as the UV is no longer powered. The Open Generator Pulse relay switches back to its closed state, ready to power the UV coil the next time the

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. Part No. 057-004

Specification

3.9.2 USB CONNECTION

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:

• DSE7400 series module

• 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 be connected to the module for configuration by PC.

NOTE:- Refer to DSE7400 Series Configuration Suite Manual (DSE part 057-160) for further

details on configuring, monitoring and control.

3.9.3 USB HOST-MASTER (USB DRIVE CONNECTION)

USB Type 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)

NOTE:- Refer to DSE7400 Series Configuration Suite Manual (DSE part 057-160) for further

details on configuring, monitoring and control.

Specification

3.9.4 RS232

The RS232 port on the controller supports the Modbus RTU protocol. The Gencomm 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.

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.

• Sierra Fastrak Xtend GSM modem kit (PSU, Antenna and modem)* DSE Part number 0830-001-01

NOTE: *For GSM modems a SIM card is required, supplied by your 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 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.

Specification

3.9.5 RS485

The RS485 port on the series controller supports the Modbus RTU protocol. The DSE Gencomm register table for the controller is available upon request from the DSE Technical 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. This allows for a large distance between the module and a PC running the DSE Configuration Suite software. The operator is then able to control the module, starting or stopping the generator, selecting operating modes, etc. The 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).

3.9.6.5 FIREWALL CONFIGURATION FOR INTERNET ACCESS

As modem/routers differ enormously in their configuration, it is not possible for DSE to give a complete guide to their use with the module. However it is possible to give a description of the requirements in generic terms. For details of how to achieve the connection to your modem/router you are referred to the supplier of your modem/router equipment.

The module makes its data available over Modbus TCP and as such communicates over the Ethernet using a Port configured via the DSE Configuration Suite software..

You must configure your modem/router to allow inbound traffic on this port. For more information you are referred to your WAN interface device (modem/router) manufacturer.

It is also important to note that if the port assigned (setting from software “Modbus Port Number”) is already in use on the LAN, the module cannot be used and another port must be used .

Outgoing Firewall rule

As the module makes its user interface available to standard web browsers, all communication uses the chosen port. It is usual for a firewall to make the same port outgoing open for communication.

Incoming traffic (virtual server)

Network Address and Port Translation (NAPT) allows a single device, such as the modem/router gateway, to act as an agent between the Internet (or "public external network") and a local (or "internal private") network. This means that only a single, unique IP address is required to represent an entire group of computers.

For our application, this means that the WAN IP address of the modem/router is the IP address we need to access the site from an external (internet) location.

When the requests reach the modem/router, we want this passed to a ‘virtual server’ for handling, in our case this is the module.

Result : Traffic arriving from the WAN (internet) on port xxx is automatically sent to IP address set within the configuration software on the LAN for handling.

NOTE:- Refer to DSE7400 Series Configuration Suite Manual (DSE part 057-160) for further

details on configuring, monitoring and control.

Maximum 40 additional inputs (All can be configured as either digital, resistive, 0-10V or 4-20mA when using DSE2131)

NOTE: As a termination resistor is internally fitted to the host controller, the host controller must be the ‘first’ unit on the DSENet®. A termination resistor MUST be fitted to the ‘last’ unit on the DSENet®. For connection details, you are referred to the section entitled ‘typical wiring diagram’ elsewhere in this document.

NOTE : DSE7400 series module does not support the DSE2510/2520 display modules.

3.10.1 DSENET® USED FOR MODBUS ENGINE CONNECTION

As DSENet® utilises an RS485 hardware interface, this port can be configured for connection to Cummins Modbus engines (Engines fitted with Cummins GCS). This leaves the RS485 interface free for connection to remote monitoring equipment (i.e. Building Management System, PLC or PC RS485 port).

While this is a very useful feature in some applications, the obvious drawback is that the DSENet® interface is no longer available for connection to expansion devices.

Example of configuring the DSENet® for connection to Cummins QST GCS using the DSE Configuration Suite Software:

3.11 SOUNDER

The module features an internal sounder to draw attention to warning, shutdown and electrical trip alarms.

Sounder level 64db @ 1m

3.11.1 ADDING AN EXTERNAL SOUNDER TO THE APPLICATION

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:
