DSE DSE7420 MKII Controller

Product Code: DSE7420MKII
Auto Mains (Utility) Failure Control Module
The DSE7420 MKII is an intelligent, powerful auto mains (utility) failure control module with high-level features and functionality. The control module is the first module in the DSE range to include in-built SNMP and features an embedded web server. The module is suitable for a wide range of single-set gas and diesel applications.

The control module features an enhanced dual core main processor and extended memory capacity. This allows the module to deliver a faster more powerful performance to return quicker operating responses on complex applications and provides enhanced memory storage for high level data logging functionality.

245 mm x 184 mm x 51 mm (9.6″ x 7.2″ x 2.0″)
220 mm x 160 mm (8.7″ x 6.3″)
8.0 mm (0.3″)
7420-03 – 7420 MKII Auto Mains (Utility) Failure Control Module






Product Highlights
Key Features Key Benefits
Configurable power-up mode. Choose to power up the module in stop / manual / auto mode.
MPU fail delay. If an MPU failure is detected the alarm can be delayed to allow for transient in the signal.
Enhanced graphical user interface. Major design changes added to V7 to make the GUI easier to understand.
Drag and drop advanced PLC editor. Powerful PLC editor functionality as standard.
MSC ID within PLC GenComm override. PLC logic can be created to change the MSC ID to avoid having to use DSE Configuration Suite on-site.
CAN support for the DSEA108 AVR. Full communication with the DSEA108 over CAN. The DSEA108 information is displayed on the front display of the control module.
Closed transition support with check sync. The load can be transferred from generator to mains (utility) or mains (utility) to generator without a break in the power supply.
Mains (utility) and generator breaker alarms. Required to ensure the closed transition function operates correctly.
Open transition support with check sync. The phase angle between generator and mains (utility) voltages is check to be in sync before the open transition limiting potential damage to rotating machinery.
Supports 7 languages. English and 6 alternative languages can be stored in the control module.
Crank disconnect on generator voltage. Provides the ability to crank disconnect on generator voltage.
Oil pressure disconnect delay. Delays the crank disconnect on oil pressure to compensate for cold oil.
DSE25XX MKII supported over DSENet®. Increases the number of supported DSE25XX MKII to two by allowing a single DSE25XX MKII to communicate over DSENet®.
Charge alternator disable functionality. Charge alternator support can be disabled. This removes all related information from the front panel editor and SCADA.
Supports escape mode. Allows an engine to be run when it has received a shutdown command related to efficiency limits.
3 digital input functions added to allow ECU specific operations. Provides additional flexibility by allowing users to turn on additional engine functionality on supported electronic engines.
Configurable icon screens. Icon layout on module screens can be configured to suit individual applications.
Embedded web server. A web interface has been added to the control module to show the same information as the PC SCADA software across the Internet. The web interface can also be used to control the
module and clear alarm conditions.
SNMP GET, SET & TRAP support built-in. Removes the requirement for additional devices.
Simultaneous use of RS485, RS232 & Ethernet ports. Provides multiple communications options.
Support for 0 V to 20 V and 4 mA to 20 mA sensors. Provides support for a wide range of sensors and parameters.
Support for 3 kΩ resistive sensors. Provides support for a wide range of sensors and parameters.
True dual mutual standby with load balancing timer. Enables two set systems to be configured to allow for redundancy or balancing run hours.
CAN, MPU & alternator speed sensing (selectable depending on engine type). Provides complete flexibility.
Tier 4 CAN engine support. Ensures the control module can be used with the latest in modern electronic engine technology.
Fuel usage monitor and low level alarms. Allows accurate tracking of fuel usage.
Power monitoring (kW h, kVAr, kv Ah, kV Ar h), reverse power protection, kW overload protection. Provides clear accurate power measurement information.
Configurable digital inputs (8). Provides multiple installation options.
Configurable analogue / digital inputs (6) Provides multiple installation options.
Configurable outputs (8) Provides multiple installation options.
Data logging facility (20 parameters). Provides current and historical status information.
4-line back-lit LCD text display Provides comprehensive and clear indication of operation and parameters.
Five key menu navigation Provides convenient and flexible navigation of parameters.
Configurable CAN instruments. Allows the control module to read and display up to 10 instruments over CAN from 3rd party devices.
Ratiometric inputs. Removes the requirement for additional devices.
Comprehensive monitoring of the mains (utility) supply and auto changeover. A genset controller and ATS in one compact housing.
Automatic load transfer control. Ensures there is no break in power when the changeover occurs.
Customisable power up text and images Company logo can be uploaded to the start up splash screen.
Customisable front panel editor. Allows different access levels to be configured for different user groups.
Configurable CT positioning. The CT can be placed in the Generator output to provide current readings and protection or alternatively placed in the main load output to provided generator and mains (utility) readings and protection.
Compatible with the 73xx MKII when it has been configured for use as a 25xx MKII Remote Display. Provides remote display functionality.
