Auto Mains (Utility) Failure Control Modules


Auto Mains (Utility) Failure Control Module
The DSE7320 MKII is a powerful, new generation Auto Mains (Utility) Failure genset control module with a highly sophisticated level of new features and functions, presented in the usual DSE user-friendly format. Suitable for a wide variety of single, diesel or gas Gen-set applications. 

Featuring a new Dual Core main processor and extended memory, the module provides faster and more powerful processing power, returning faster operational responses on intensive applications and increased functionality, with data logging facility. 

Monitoring an extensive number of engine parameters, the module will display warnings, shutdown and engine status information on the back-lit LCD screen, illuminated LED's, remote PC's and via SMS text alerts (with external communication device).

Key Features & Benefits

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.
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.
Supports escape mode.
Allows an engine to be run when it has received a shutdown command related to efficiency limits.
Configurable icon screens.
Icon layout on module screens can be configured to suit individual applications.
Comprehensive monitoring of the mains (utility) supply and auto changeover.
A genset controller and ATS in one compact housing.
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.
Support for up to three remote display units
Provides the option to mimic the main control module up to 1.2 km.
Configurable inputs (8)
Provides multiple installation options.
Configurable analogue / digital inputs (6)
Provides flexibility for multiple installation options.
Configurable outputs (8)
Provides multiple installation options.
Tier 4 CAN engine support.
Ensures the control module can be used with the latest in modern electronic engine technology.
Manual fuel pump control.
Allows the fuel tank to be filled to provide reassurance of system operation.
Power monitoring (kW h, kVAr, kv Ah, kV Ar h), reverse power protection, kW overload protection.
Provides clear accurate power measurement information.
Mains monitoring and automatic start and changeover to generator power in the event of a mains (utility) out of limits or failure.
Provides the reassurance of back up power being available in an emergency.
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.
Data logging facility
Provides current and historical status information.
Customisable power up text and images
Company logo can be uploaded to the start up splash screen.
Support for 0-10 V & 4-20mA oil pressure senders.
Provides support for a wide range of sensors and parameters.
Can be configured for use as a remote display module
Single product can be used for dual functionality.
