When debugging the generator set, professionals will remind the user to carry out an overhaul every few weeks to ensure that the generator set is in good working condition and can be put into use quickly in an emergency. Sometimes the standby unit fails to start, what is the reason? This article analyzes for you.
1. Diesel generator can not start automatically
- This is the more common cause of failure to start, check that the switch is not left in the OFF reset position and the emergency stop button is not pressed. Always double-check this after work or maintenance has been performed on your generator to ensure your generator will continue to start automatically when backup power is required.
2. Starter battery failure
- Batteries that have been idle for extended periods can accumulate too much lead sulfate on their plates if they are not kept fully charged, or if they are discharged and charged too many times. This could result in the battery not charging or not starting at all. Generally speaking, if the battery has been idle or has been used for more than three years, it is time to replace it.
3. Liquid leakage
- Oil, fuel, or coolant leaks can prevent the generator from starting. Maintenance, including hose and coolant replacement, can effectively prevent this from happening.
4. Fuel problem
- Not having enough fuel can also be one of the reasons for the inability to start. Regularly perform a direct visual inspection of the fuel level in the tank and top it up as needed.
- Likewise, too much fuel could be a factor. If too much fuel is added, the high fuel level alarm will sound.
- Spoiled diesel fuel can also cause problems with generators. Diesel can degrade over time, especially when water gets into the tank. Water in the fuel tank encourages microbial growth and can clog fuel filters and restrict fuel flow to the engine. Check the fuel regularly for discoloration or unusual odors.
5. Coolant problem
- Low coolant levels and low coolant temperatures may prevent your generator from starting. The coolant level is low, most likely due to an external or internal leak. If the coolant does not cool down or does not flow properly due to a radiator problem, it can cause the engine to overheat.
