9 SENSOR SETTING
─ When sensors are reselected, sensor curve will be transferred into the standard value. For example,
if temperature sensor is SGH (120°C resistor type), its sensor curve is SGH (120°C resistor type); if
it is SGD (120°C resistor type), the temperature sensor curve is SGD curve.
─ When there is difference between standard sensor curves and used sensor, user can adjust it in
“curve type”.
─ When sensor curve is inputted, X value (resistor) must be inputted from small to large, otherwise,
mistake occurs.
─ If there is not oil pressure sensor, but there is only low oil pressure alarm switch, user must set the
oil pressure sensor as “None”, otherwise, maybe low oil pressure shutdown occurs.
─ The headmost or backmost values in the vertical coordinates can be set as same as below:

10 COMMISSIONING
Please make sure the following checks are made before commissioning:
— Ensure all the connections are correct and wire diameter is suitable.
— Ensure controller DC power has fuse, and controller’s positive and negative connection with start
battery are correct.
— Take proper action to prevent engine from crank success (e. g. remove the connection wire of fuel
valve). If checking is OK, make the start battery power on; choose manual mode and controller will
execute routine.
— Set controller under manual mode, press “start” button, genset will start. After the cranking times preset,
controller will send signal of Start Failure; then press “stop” to reset controller.
— Recover the action to prevent engine from crank success (e. g. connect wire of fuel valve), press start
button again, genset will start. If everything goes well, genset will goes normal running after idle speed
running (if configured). During this time, please watch for engine’s running situation and AC generator’s
voltage and frequency. If something abnormal occurs, stop genset and check all wire connections
according to this manual.
— If there is any other question, please contact SmartGen’s service.
