The DSE5520 is an AutomaticMains Failure Control Moduledesigned to provide advanced loadshare functionality for diesel andgas generating sets that includenon electronic and electronicengines. The module also providesexcellent engine monitoring andprotection features.

The module monitors the mains(utility) supply and upon detectionof a loss in power automaticallystarts the generating set.

The module’s synchronisingfunctions include automaticsynchronising with built insynchroscope and closing ontodead bus. Direct and flexibleoutputs from the module areprovided to allow connection tothe most commonly used speedgovernors and automatic voltageregulators (AVRs).

The module has the ability tomonitor under/over generator volts,over current, under/over generatorfrequency, under speed, overspeed, charge fail, emergencystop, low oil pressure, high enginetemperature, fail to start, low/highDC battery volts, fail to stop,generator short circuit protection,reverse power, generator phaserotation error, earth fault protection,loss of speed signal, fail to open,fail to close, out of sync, MPUopen circuit failure, negative phasesequence and loss of excitation.

OPERATIONThe module is operated using the front STOP/RESET, MANUAL, AUTO andSTART pushbuttons. Three of these push buttons include an LED indicator.Additional pushbuttons provide LCD display scroll, lamp test, mutefunctionality and breaker control.

BUILT-IN FUNCTIONS• Alternator under/over volts• Alternator under/over frequency• Warning or shutdown on engine temperature, over/under speed, oilpressure

• Warning, shutdown or electrical trip on battery volts or over current• Shutdown or electrical trip on reverse power, phase rotation or shortcircuit fault

• Earth fault shutdown• Adjustable crank cycle/attempts• Full remote control and telemetry• 9 configurable digital inputs• 5 configurable and 2 fixed relay outputs• System lock input• Load switching control push-button inputs• Restricted access to programming via PIN number• Loss of excitation• Negative phase sequence• ROCOF/vector shift (mains (utility) decoupling)• Peak lopping• Peak shaving• Mains (utility) reverse power

INSTRUMENTATION ANDALARMSThe DSE5520 module provides advanced metering and alarm functionalityvia the LCD display. The information can be accessed using the display scrollpushbuttons. The table below shows the instrumentation and alarm featuresthe module provides.

TELEMETRYThe module gives the user fulltelemetry facilities when using theoptional communications software.The module can be connected to aPC using the DSE810 PC interfaceor by using a suitable modem.

The PC software is MicrosoftWindows™ based. All access intothe module can be configured tobecome password protected toprevent unauthorised entry. ThePC software allows the module tobe controlled from a remote location.

COMMUNICATIONSThe DSE5520 has a number ofdifferent communicationcapabilities.

SMSMessagingWhen the module detects an alarmcondition, it has the ability to sendan SMS message to a dedicatedmobile number, notifying an engineerof the problem. (GSM Modem andSIM Card required).

Remote CommunicationsWhen the module detects an alarmcondition, it dials out to a PCnotifying the user of the exact alarmcondition (modem required).

BuildingManagementThe module has been designed tobe integrated into new and existingbuilding management systems.

PC SoftwareThe module has the ability to becontrolled, configured and monitoredfrom a remote PC, using theDSE810 interface.

EVENT LOGThe module includes acomprehensive event log thatshows the 25 most recent alarmconditions and the date and timethat they occurred. This functionassists the user when fault findingand maintaining a generating set.
