4 pole 230 V 50 Hz. RPM 1500 4 pole 120/110 V 60 Hz. RPM 1800 Run the genset check the frequency and correct the RPM.

Greetings ! Could you please give further information ? Is this Genset overspeed at first start, or any time when you crank it overspeed?

@@northjayhoon9789 every time when we start the gen set trip on over speed, over speed setpoint is 1650, speed probe is healthy, engine trips during cranking

Thank you for your info, Your Genset RPM should be 1500, Your generator voltage 230 volts and 50Hz at 1500 RPM If you don't have any issue with fuel line and injection pump, your engine RPM should remain the same rpm ,even after loading In this case adjust the engine RPM at 1550 and then load the genset see if the engine RPM remain at 1500 if so! your problem solved.

Greetings Thank you for your inquiries I'm wondering if you could tell me about your Genset controller First I need to know about Genset controller and then we need to finde the event code , after that I can tell you what problem you have with your generator.

@@northjayhoon9789 Engine all parameter shown on ( Enercon Simatic HMI)

Kw fault code can be displayed on generator overview It tells us the generator was overloaded Calculate the current on generator overview parameters when it is fully loaded and then check the maximum current shown at your Genset ,if it is loaded 100% which mean you need to reduce the load It should not be load more than 80%

Thanks a ton Sir.

Greetings! Thank you for your enquiries. You got 2 MPU , one of the sensor is responsible for your starter motor while you cranking the engine, as soon as the engine starts the sensor sends the signal to the GSC the GSC cuts the power on starter motors relay meanwhile the starter motor disengage. The second MPU is monitoring the engine speed when you loading the generator the RPM drops and the GSC (Genset Controller) accelerate the engine through the LCG. However some engines have only one MPU but twin are more reliable.

Check your battery voltage make sure it is fully charged otherwise you have problem either with starter motors solenoid or relay please click on this link watch this video it could solve your problems. czcams.com/video/W8UOMo2-gVE/video.htmlsi=nSVv097Oid6tu8Uj

Thank you for your enquiry ! Will try with another video.

Please, can you give me your WhatsApp number so I can send you a video clip of this problem

Greetings Thank you for your enquiry! Can you tell me about RPM and the voltage in your country? If the voltage is 110 v 60Hz the RPM should be 1800 for 220 v 50Hz the RPM should be 1500. First make sure stabilize your engine speed , either there is problem with your fuel line or the injectors are bad . 01 Check the fuel line and the pump pressure . 02 inspect the injectors . If they are all ok Do a compression test make sure you don't have any problem with your engine after inspection when you got all ok the engine speed stabilized , check the voltage if still the voltage fluctuating please check the AVR.

the RPM 50/52/48 And Voltage 400/420/389/380

Speed ​​and voltage are unstable

Thank you for your enquiry! If your generator's controller indicates/ warning high battery alarm, definitely you need to check DC alternator . An alternator's output is controlled by an integrated voltage regulator, which is designed to prevent overcharge. You may have a faulty voltage regulator and it does over charge your battery.

Glad it was helpful!

Will upload soon

Glad I could help

Glad it helped!

Greetings If you have already check the wires : L N 3c Ground The next step is to check all components at the PCB in the outdoor unit if everything looks good at the outdoor next check the PCB board at the indoor units.

Greetings If you have replaced the sensor and still have the same problem please check those two wires which connected to the sensor either there is loose connection or one of the wire has been corroded. Note:for loose connection you need the inspect the sensor connector If there is loose connection engine vibrations will cause loose the signal.

@@northjayhoon9789 Hello, thank you for your information, I replaced the harness by making a new one other than the one it came with and it continues to present the problem, I believe that the problem is caused by the fuel, I notice that the engine slows down as the load of each section of the hotel where it is installed. Sometimes you have to turn it on up to 3 times for it to start.

Greetings Unexpected shutdown is an electrical problem, it happens if there is loose connection where the negatives circuits are grounded at the engine, or there is power interruption happens with circuit which is supplying power to the fuel cut solenoid .

@@northjayhoon9789 appreciated sir!

Did you get it resolved?

Greetings First start overspeed means there is a problem with the fuel line The fuel from filter housing returns back to the fuel tank after some hours , while the generator is standby In this situation before you start the engine please run the prime pump for two minutes and start the engine , if the engine did not overspeed which mean the fuel line gets empty when it is standby for two or three hours Note: if your generator doesn't have an electric fuel prime pump Pump it manually.

Greetings Thank you for your request Please send me an email to north.jayhoon@gmail.com I will send you the wiring diagram. All the best

Could you please tell further about local connectivity? Is this generator running as a backup?

Thank you for your consideration This is a 12 years old generator the previous service providers screws up everything We have been trying to fix them.

Greetings Check the input circuits at the indoor PCB make sure they are ok you may have a blown fuse once you figure out with the current problem that you mentioned your AC is off at all not starting After you are able to run the unit connect a single wire to the 3c circuit in indoor and the other end of wire should reach to the outdoor connect it to the 3c circuit of outdoor this wire should be isolated from the rest of wire Run the AC unit and wait 20 mins if the erro comes back then you need to check the PCB board at the outdoor there are so many component you have to check sometimes the PCB itself goes bad

Hi, you found the problem yet? I have the exactly issue like you. I haven't checked the wire yet. Ch05 shown up occasional after 30 min or so. After I turned off everything for any hour or so, it will be back to normal, depending on luck.

How much does it cost to do this work?
