What to do if the circuit breaker trips on my AirMan Portable Generator?
If the circuit breaker trips on your AirMan Portable Generator, it could be due to an overload or a short circuit on the load side. Try reducing the load. If that doesn't work, identify and eliminate the cause of the short circuit.
What to do if the starter rotates but the AirMan SDG400S-8E1 Portable Generator engine doesn't start?
If the starter of your AirMan Portable Generator rotates normally but the engine doesn't start, it could be due to several reasons: * No diesel fuel oil: Replenish the fuel. * Air mixing in fuel piping: Bleed the air. * Fuel filter clogging: Disassemble, clean, and change the filter. * Nozzle clogging: Disassemble and clean the nozzle. * Malfunction of controller: Check the fuse, connector, and controller.
What to do if my AirMan Portable Generator displays “Engine Oil Pressure Low”?
If the monitor screen of your AirMan Portable Generator displays “Engine Oil Pressure Low”, this could be due to: * Engine oil shortage: Replenish the oil. * Engine oil filter clogging: Change the filter. * Loosened or disconnected wiring, or connector: Check and tighten the wiring or connector. * Oil pressure switch malfunction: Change the switch.
Why won't the starter rotate on my AirMan Portable Generator?
If the starter of your AirMan Portable Generator doesn't rotate or has a low revolution speed, it could be due to: * Battery malfunction: Check the battery; charge or change it. * Charging malfunction: Change the charging system. * Alternator malfunction: Change the alternator. * Starter malfunction: Change the starter.
What causes a 'Water Temperature High' message on my AirMan SDG400S-8E1 Portable Generator?
If the monitor screen of your AirMan Portable Generator displays “Water Temperature High”, it could be due to: * Shortage of coolant: Replenish the coolant. * Slip of belt: Adjust the tension. * Radiator clogging: Clean the radiator. * Faulty thermostat: Change the thermostat. * Looseness, disconnection of wiring or connectors: Check and tighten the wiring or connectors. * Faulty coolant temperature switch: Change the switch.
Why is my AirMan SDG400S-8E1 Portable Generator producing no voltage or low voltage?
If your AirMan Portable Generator generates no voltage or too low voltage even when operated at a rated speed, the possible causes are: * Poor tightening of terminals: Check and tighten the terminals. * Broken or short-circuited circuit to exciter field winding: Repair the circuit. * Faulty exciter: Repair the exciter. * Function circuit protector (CP) for AVR protection: Reset the circuit protector. * Faulty AVR: Change the AVR. * Broken or short-circuited winding of generator main machine: Repair the winding. * Faulty silicon rectifier (mounted on generator main machine rotor): Change the rectifier. * Faulty voltmeter: Change the voltmeter.
Why is my AirMan SDG400S-8E1 Portable Generator generating too high voltage?
If your AirMan Portable Generator is generating too high voltage, even when set at the rated frequency and the voltage regulator knob is turned, the issue might be: * Loosened or disconnected wiring, or connector to AVR: Check and tighten the wiring or connector. * Broken wire or poor contact of AVR variable resistor: Repair or change the resistor. * Faulty AVR: Change the AVR.
Why is the voltage unstable on my AirMan SDG400S-8E1 Portable Generator?
Unstable voltage generation in your AirMan Portable Generator can be caused by: * Poor tightening of each terminal: Check and tighten each terminal. * Function circuit protector (CP) for AVR protection: Reset the circuit protector. * Faulty AVR: Change the AVR.
What does “Containment Level” mean on my AirMan Portable Generator?
If the monitor screen on your AirMan Portable Generator displays “Containment Level”, it could indicate: * Condensate accumulated in the oil fence: Drain the condensate. * Oil fence level sensor is not functioning: Check or change the sensor.
