DKG 705 AMF ATS - Home Mega Global Solution

DESCRIPTIONThe DKG-705 is a comprehensive AMF unit for a singlegenerating set operating in standby or parallel withmains modes. The unit has two option levels, thestandard version being for standby and the ‘full’ one forparallel with mains applications.In AUTOMATIC position, DKG-705 monitors mainsphase voltages and controls the automatic starting,stopping and load transfer of the generating set in caseof a mains failure and once the generator is running, itmonitors internal protections and external fault inputs. Ifa fault condition occurs, the unit shuts down the engineautomatically, indicates the failure source on the LCDdisplay and turns on the red ALARM led.The DKG-705 unit is able to transfer the load betweenmains and genset in 4 different ways:-transfer with interruption: there will be a powerinterruption period duration during the transfer-no break transfer without synchronization: transferwill be made without power interruption. The unit waitsuntil mains and generator phases match and makes aquick transfer.-no break transfer with synchronization (availableonly with ‘full’ version): transfer will be made withoutpower interruption. The unit operates the governor andAVR control outputs to synchronize the generator withthe mains and makes a quick transfer.-soft transfer (available only with ‘full’ version): transferwill be made without power interruption. The unitoperates the governor and AVR control outputs tosynchronize the generator with the mains and makes asmooth ramped transfer.The operation of the unit is controlled with front panelpushbuttons. The LOAD TEST, TEST, AUTO and OFFpushbuttons select the operating mode. Other buttonsselect the program mode entry/exit, display parameterscroll, alarm mute and lamp test functions.The DKG-705 provides a comprehensive set of digitallyadjustable timers, threshold levels, input and outputconfigurations and operating sequences. Theunauthorized access to program parameters is preventedby a 3 level password system. All programs may bemodified via front panel pushbuttons, and do not requirean external unit.The fault conditions are considered in 3 categories asWarnings, Load-dumps and Alarms. Measured valueshave separate programmable limits for warning andalarm conditions.The service request indicator lamp turns on at theexpiration of either engine hours or time limits.It is possible to monitor the operation of the systemlocally or remotely with the WINDOWS based PC utilityprogram.The unit is designed for front panel mounting. It is fittedinto the cut-out with steel springs removed. Connectionsare made with 2 part plug and socket connectors.STANDARD MEASUREMENTSGenerator Volts: U-N, V-N, W-NGenerator Volts: U-V, V-W, W-UGenerator Amps: U, V, WGenerator KW: U, V, W, totalGenerator KVA: U, V, W, totalGenerator KVAr: U, V, W, totalGenerator pf: U, V, W, averageGenerator Frequency,Mains Volts: R-N, S-N, T-NMains Volts: R-S, S-T, T-RMains Frequency,Synchronoscope Phase AngleSynchronoscope Voltage Match U-RBattery VoltageEngine RPMEngine Coolant TemperatureEngine Oil PressureEngine Oil TemperatureEngine Fuel LevelOPTIONAL MEASUREMENTS (‘full’ version only)Mains Amps: R, S, TMains KW: R, S, T, totalMains KVA: R, S, T, totalMains KVAr: R, S, T, totalMains pf: R, S, T, averageSTATISTICSFollowing incremental counters provide statistics aboutpast performance of the generating set:Generator KWh, KVAh, KVArhEngine Hours RunEngine Hours to ServiceTime to ServiceNumber of Engine CranksNumber of Genset RunsNumber of Genset on LoadDIGITAL INPUTSThe unit has 8 fully configurable digital inputs. Eachinput has following programmable parameters:-input channel name: selectable from a list of 32,-alarm type: shutdown / load-dump / warning / no alarm-alarm polling: on engine running / always-latching / non-latching operation,-contact type: NO / NC-switching: BAT+ / BAT-ANALOG INPUTSEngine analog inputs are provided for followingfunctions:-Coolant temperature-Oil pressure-Oil temperature-Fuel levelThe analog inputs connect to resistive sender units toprovide precise and adjustable protection. The inputshave programmable sensor characteristics so that theyare suitable for any type and any brand of sensors.RELAY OUTPUTSThe unit provides 7 relay outputs with programmablefunctions, selectable from a list of 112 entries.In addition to genset control signals any specific alarminformation may be output as a relay contact.Using two DKG-705 Relay Expansion Modules, thenumber of relays may be increased up to 23, 16 of thembeing volt-free contacts.
