sounds if no throttle cable is connected and your running it off the govennor to be asking this question ,(if it had a throttle cable increasing it would bring speed up) the govenor speed is adjustable by the little screw on the top of carbarator that is connected to silver half moon (looking clip) use care to not overspeed engine if done while running , and a little bit goes a lot on the screw

Locked Rotor is reported as an overcrank fault "OC".

You first need to verify the engine fails to crank, which is likely a starter motor or start circuit failure.

If the engine cranks three separate times and then the OC fault occurs, it simply means the engine did not run... more likely a fuel issue.

But either can be caused by numerous reasons.

I think you can ask your supplier, they most know their generator.
If you plan to have a new diesel generator set, maybe you can consider Cummins, Volvo, Perkins, as well as China made generator: Yuchai, Shangchai, Weichai, Ricardo etc.
Here is the website:

Are there any faults listed on the control display? If display is dark then likely a battery issue. Check battery voltage with a Digital Multi Meter (DMM). It should be at least 12.5VDC.

Six steps of start-up Shangchai generator set :
A.Unscrew the deflation screw on the fuel injection pump, use the fuel hand pump to remove the air in the fuel system, and fix the adjusting control handle on the throttle position of the suitable starting speed;
B.Pressthe generatorstart button to start the diesel engine. If the diesel engine can't start in 10 seconds (up to 15 seconds), it should wait for 1 minute before starting for the second time. If it can't start for three consecutive times, should check and find out the cause of the failure;
C.After diesel generator set start up, the no-load speed gradually increases to 1000-1200 r/min (note not to run at low speed for a long time). After the diesel engine is preheated, the speed is increased to the rated speed. When the outlet water temperature reaches 55 degrees Celsius and the oil temperature reaches 45 degrees Celsius, full load operation is allowed;
D.After starting the diesel engine, pay close attention to the reading of oil pressure gauge (2.5-3.5kg/C?in normal operation). If the oil pressure gauge does not indicate, stop immediately and check whether the ammeter has charge indication;

E.After the diesel generator set is put into normal operation, should observe the changes of water temperature, oil temperature and oil pressure at any time, and should handle the reading of power meter, frequency meter, ammeter and voltmeter in time if abnormalities are found;
F.When each instrument of the genset indicates normally, can turn on the load switch to send power to the load. With the change of load of the genset, if the frequency and voltage are not within the prescribed range, should adjust the frequency and voltage in time to maintain the rated value. It is strictly prohibited that the genset carry load at low speed, so as to avoid damage to the equipment.

if you have an scr pack, that has 6 pins, there are two for ac, two for gates, and two for the excitation field.
The two gate wires come off your adc controller.

Safety shutdowns:
  1. Loss of coolant
  2. High water temperature
  3. Low oil pressure
Likely one of these. If no indicators at a panel check at the connector.
