This Time We Will Trouble Shooting In A Diesel Generator
Machine specification data :
-Enggine = Donfeng Cummins 6BTA5.9G2 ,
Prime 106KW at 1500 Rpm
- Generator = MAGNA Plus Singkronous AC Generator 80 KW
- Controler = SmartGen HGM 6100N Series
- AVR = SE 350 Regulator
this is video part 2 and in this video I will specifically describe the steps on how to fix the generator under voltage alarm and shutdown caused by Lost power sensing
before the controller shutdown the engine,
we can see here , the voltage read by the display is not Balanced.
and because the voltage read by the controller has exceeded the lowest voltage allowed to operate this generator,
the controller orders the engine to die, by disconnecting the Fuel Relay voltage,
in cases like this.
we have two possible analyzes to do trouble shooting
The first possibility, is that the controller is already damaged.
it is possible that the two,
voltages received by the controller are indeed unstable
To be sure, we have to make measurements manually at the 3-phase input terminal of this controller voltage
Come on guys, let's look at this controller's manual ,
to determine the voltage input terminal , For us to do voltage measurements manually with a multitester.
this is the problem, that occurs in the current controller.
this is a 3 phase Input Point terminal, and here we have to do Voltage Measurements manually, Using a Multitester.
and this is, the description of the terminal
In this case, I have measured the input voltage at the Terminal controller,
and found that the voltage received by the controller, is indeed unstable
In standard installations, the input voltage to the controller, is usually taken directly from the generator output terminal,
without going through a breaker
Okay friends, for the next step, let's check the condition of the generator output terminal
it turns out that it's true friends,
here we can see that there is a loose Terminal connection.
Let's open the cover of the generator cable terminals, and let's see how bad the damage is
Okay friends, after we fix the damage, let's try to restart this generator
it seems that the overall reading of the voltage 3 phase , is read properly and normally
and Let's try, to put a load of about 17 amperes on this generator,
and see what happens
Here we can see, that the voltage readings are balanced and the generator is not shutting down again.
which means, we have solved the problem with this generator
