Step: 1 kW; Range: 1 . 3000 kW CT Ratio Gen.set phases current transformers ratio. Step: 1 A; Range: 1 . 5000 A / 5A PT ratio Gen.set potential transformers ratio. Step: 0,1 V / V; Range: 0,1 . 500,0 V / V Nominal freq Nominal generator frequency (usually 50 or 60 Hz ) Step: 1Hz; Range: 45 . 65 Hz Gear teeth Number of teeth on the engine gear for the pick.up. Set to zero, if no pick.up is used. Engine speed is counted from the generator frequency. Step: 1; Range: 0 . 500 Note: Generator frequency can be used only when generator voltage (min 5V) is present before reaching of the firing speed (Starting RPM) after start. Nominal RPM Nominal engine speed. Step: 1RPM; Range: 100 . 4000 RPM. FLTRESGOTOMAN DISABLED: Controller stays in AUT mode after Fault reset . ENABLED: Automatic switch from AUT (or TEST) to MAN mode after Fault reset to avoid automatic engine start. This function is active for Shut down protection only. DispBackLightTO Timeout after which the display backlight is switched off. Step: 1 min Range: 0 . 60 min Default value: 0 = the display lights all the time Mode IL [ OFF, MAN, AUT ] Equivalent to Controller mode changes by MODE or MODE buttons. Note: Controller Mode change can be separately password protected. RS232 mode [Standard/Modbus ] Communication protocol switch. Standard: LiteEdit communication protocol. Modbus: Modbus protocol. Note: For detail description see chapter Modbus protocol. Num rings AA Number of rings prior to open modem connection. Step: 1; Range: 1 . 30 Note: NumberRings AA change is not activated immediately. It is activated after controller is switched on or when modem is connected to controller. 4-14 Operation MN2417 Table 4-10 Engine Setpoints Start RPM “Firing” speed when iL controller stops cranking (starter goes OFF). Step: 1% of nominal RPM; Range: 5 . 50 % Starting POil When reached controller stops cranking (starter goes OFF). Step: 0,1 psi; Range: .100 . 10000 Note: There are three conditions for stop cranking: Starting RPM, StartingPOil and D+ (when enabled). Starter goes off when any of these conditions is valid. Prestart time Time of closing of the PRE.START output prior to the engine start. Set to zero if you want to leave the output PRE.START open. Step: 1s; Range: 0 . 600 s MaxCrank time Maximum time limit of cranking. Step: 1s; Range: 1 . 60 s CrnkFail pause Pause between crank attempts. Step: 1s; Range: 5 . 60 s Crank attemps Max number of crank attempts. Step: 1; Range: 1 . 10 Idle time Idle time delay starts when RPM exceeds Start RPM . Start fail is detected when during Idle state RPM decreases below 2. During the Idle time timer running the binary output IDLE/NOMINAL is opened, when it elapses the IDLE/NOMINAL output closes. Binary output IDLE/NOMINAL opens during Cooling period again. Step: 1 s; Range: 0 . 600 s Note: If the IDLE function not supported on the governor, set the Idle time nevertheless to minimum 5s to avoid Underspeed possibly caused by instability of the engine short after start. GCB CloseDelay GCB can be closed earliest GCB CloseDelay after Stabil time when all electric values are in overunder voltage and over.under frequency limits. Step: 1 s; Range: 0 . 300 s Stabil time Generator Nominal voltage is detected during genset start after starter is switched off and Idle time elapses. Electric generator protections are active since detection. Step: 1 s; Range: 0 . 300 s MinStpValvTime Binary output Stop solenoid closes when stop sequence begins and closes at least for MinStpValvTime. Example MinStpValvTime = 20 sec. a) When engine stops (RPM=0) in 10 seconds, Binary output Stop solenoid still stays closed for 10 sec. b) When engine stops in 30 seconds, Binary output Stop solenoid opens 10 seconds after RPM=0 and Vg =0 and Oil pressure = 0. Those 10 sec is fix time for safe stop. Step: 1s; Range: 0 . 180 s Note: Stop of engine is detected when all following conditions are met: RPM =0, Oil pressure < StartingPOil and Generator voltage < 10 VAC. Stop fail is detected when is difference between those conditions, e.g RPM=O and Generator voltage > 10V.

Step: 1s; Range: 0 . 3600 s AfterCoolTime Runtime of engine after cooling pump. Binary output Cooling pump is closed when the engine starts and opens AfterCool time delayed after gen.set stops. Step: 1s Range: 0 . 3600s CoolingSpeed Selects the function of the Binary output IDLE/NOMINAL during engine Cooling state. NOMINAL : Cooling is executed at Nominal speed and generator protections are active. IDLE: Cooling is executed at Idle speed and generator protections are switched off. Hint: Binary output IDLE/NOMINAL must be configured and connected to speed governor. Engine Idle speed must be adjusted on speed governor....
