Start, Zeroload, Work Governor handle Preheat Stop Run Start CAUTION - If the engine needs emergency stop, please hold the "emergency stop" key until the engine stop. - - CAUTION Don't decrease the speed by using the governor handle or frequency-regulation knob when driving the appliance load. The voltage and frequency will decrease if the speed is reduced, which may result in fault. 4. CONNECTION OF THE LOAD 4.1 the choice of the electric cable The choice of the electric cable depends on the allowable current of the cable and the distance between the load and the generator. And the cable section should be big enough. If the current in the cable is bigger than the allowable current, it will become over hot and the cable will be burnt. If the cable is long and thin, the input voltage of the electric appliance will be not enough, causing that the generator doesn't start. In the following formula, you can calculate the value of the potential "e". Potential (v) = 1 58 Length Section area Current (A) 3 3. Electric fan Electric fan is installed in the radiator. Please make sure that the fan can rotate, and there is no noise of the fan or abnormal vibration. As the power of the electrical fan is delivered from the generator, it wouldn't rotate when engine is just started, or idle at the low speed. The power indication lamp will light and electric fan will start if the engine speed increases to deliver electricity. Once the voltage reaches a stable state, the electric fan will go on rotating even if the engine speed decreases. Long time low-speed idles after starting or idles soon after stopping the engine may result in abnormal rising of the cooling water temperature. Increase the speed of the engine to generate the stable electricity and make the cooling fan work automatically, if the unit has to idle for a long time. If there is over current or short circuit in the electric fan, or something entangled by the fan, please cut off the power and check the following parts: Fuse If the fuse near the single-phase breaker in the control box is burnt off, please check the fault reason and replace the fuse if necessary. Make sure the electric fan can function well. Circuit protector If circuit protector of the electric fan is at OFF position, eliminate the fault and turn it to ON position to check if the electric fan can rotate normally or not.
