DKG-705 AUTOMATIC MAINS FAILURE AND REMOTE START ...

DATAKOMDKG-705 User’s ManualGroup Param. Definition Unit Min Max Description10 A12 Max PhaseDifferenceDeg. 0 20 This is the maximum phase difference betweenthe mains phase-R and the genset phase-U toenable a NO Break Transfer. Note that theDKG-705 adjusts the GOV output to bring thegenset to the same phase with the mains.10 A13 Governor Start - 0 255 This is the rest value of the governor controloutput. Always set this value to 128, which isthe mid-course. However, if needed, enginefrequency adjustment may be made throughthis parameter.10 A14 AVR Start - 0 255 This is the rest value of the AVR control output.Always set this value to 128, which is the midcourse.However, if needed, genset voltageadjustment may be made through thisparameter.10 A15 Frequency LockGain- 0 255 This parameter defines the reaction speed ofthe governor output to phase differencesbetween genset and mains phases duringsynchronization. The standard value for thisparameter is 32. But it must be readjusted forthe engine during manufacturing. If thisparameter is too high, a phase oscillation mayoccur. If it is too low, the phase locking will beslower.10 A16 AVR Gain - 0 255 This parameter defines the reaction speed ofthe AVR output to voltage differences betweengenset and mains phases duringsynchronization. The standard value for thisparameter is 64. But it must be readjusted forthe genset during manufacturing. If thisparameter is too high, a voltage oscillation mayoccur. If it is too low, the voltage matching willbe slower.10 A17 Genset PowerRatingKW 10 2400 This value will be used in future load sharingoption.10 A18 KW Ramp KW/s 0 240 In case of a soft transfer, the load’s activepower (KW) will be transferred to the mainswith this rate.10 A19 KVAr Ramp KVAr/s 0 240 In case of a soft transfer, the load’s reactivepower (KVAr) will be transferred to the mainswith this rate.10 A20 KW Gain - 0 255 This parameter defines the reaction speed ofthe KW control during soft transfer. Thestandard value for this parameter is 64. But itmust be readjusted for the genset duringmanufacturing. If this parameter is too high, aKW oscillation may occur. If it is too low, theKW transfer will be slower.10 A21 KVAr Gain - 0 255 This parameter defines the reaction speed ofthe KVAr control during soft transfer. Thestandard value for this parameter is 64. But itmust be readjusted for the genset duringmanufacturing. If this parameter is too high, aKVAr oscillation may occur. If it is too low, theKVAr transfer will be slower.10 A22 Controller ID - 0 15 This is the address of the unit in aninterconnected group for use in paralleloperation.705-UE.doc - 49 -
