This parameter isused for the calculation of the engine rpm.If this parameter is set to ‘0’ then themagnetic pickup input is not used.P_626=1 : This is the multipliercoefficient of the alternator when theengine RPM is computed from the gensetfrequency.6 620 Hysteresis Voltage V 0 30 This parameter provides the mains andgenset voltage limits with a hysteresisfeature in order to prevent faulty decisions.For example, when the mains are present,the mains voltage low limit will be used asthe programmed low limit P_512. When themains fails, the low limit will be used asP_512+P_620. It is advised to set thisvalue to 10 volts.705-UE.doc - 40 -
DATAKOMDKG-705 User’s ManualGroup Parameter DefinitionUnit Min Max Description6 621 Engine Heating Type - 0 2 This parameter defines the engine heatingmethod. The genset will not be put underload before engine heating is completed.0: engine is heated during the perioddefined by the Engine Heating Timer(P_622).1: engine is heated until the coolanttemperature reaches the temperaturedefined by Engine Heating Temperature(P_623).2: engine is heated until the coolanttemperature reaches the temperaturedefined by Engine Heating Temperature(P_623) and at least during the perioddefined by the Engine Heating Timer(P_622).6 622 Engine HeatingTimerSec 0 240 This is the period used for engine heatingfollowing the program parameter P_621.6 623 Engine HeatingTemperature?C 0 80 This is the temperature which is used forengine heating following the program6 624 Maintenance Period(Engine Hours)6 625 Maintenance Period(Days)6 626 RPM from GensetFrequencyparameter P_621.h. 0 2500 The SERVICE REQUEST led indicator willturn on after this quantity of engine hoursfrom the last service. This is useful toprevent the periodic maintenance frombeing omitted. If the period is set to ‘0’ noSERVICE REQUEST will be indicateddepending on engine hours, howeverservice may still be requested on a timelimit basis (see also parameter P_625).day 0 2500 The SERVICE REQUEST led indicator willturn on after this amount of time from thelast service. This is useful to prevent theperiodic maintenance from being omitted. Ifthe period is set to ‘0’ no SERVICEREQUEST will be indicated dependingtime, however service may still berequested on an engine hours basis (seealso parameter P_624).- 0 1 Following the value of this parameter, theRPM display will use either the magneticpickup input or the genset frequency forengine RPM calculation.0: The magnetic pickup inputs are used forRPM calculation. The magnetic pickupfrequency will be divided by P_619 (CrankTeeth Count).1: The genset frequency is used for engineRPM calculation. The genset frequency willbe multiplied by P_619 (Crank TeethCount / Multiplier Coefficient).Thus for 1500 rpm gensets, P_619= 30,For 3000 rpm gensets, P_619= 60.6 627 Genset L-L Voltages - 0 1 0: Display genset L-N voltages,1: Display genset L-L voltages.6 628 Mains L-L Voltages - 0 1 0: Display mains L-N voltages,1: Display mains L-L voltages.705-UE.doc - 41 -
