20 Most Recent Pramac GBW30P Encl Diesel Genset w/Perkins Eng Questions & Answers


Water level, good thermostat, good water pump, fan working? All things to check.

Sometimes an airlock will prevent water circulation

ALSO verify your temp gauge and sensor is working correctely. A failure of these may appear as high temp and even shut machine down if the sensor is bad.

The leakage fault of diesel generator is usually caused by the injection of corrosive coolant or seawater into the water radiator of the diesel engine.

Cause of failure: 1. The cooling water added to the cooling water radiator by operator is seawater, which results in the damage of internal waterway and external interface of diesel engine. Therefore, the use of diesel engines must be strictly in accordance with the provisions of the diesel engine operation. 2, the operator feed water radiator in the addition of strong anti-freeze corrosion, resulting in diesel engine waterway parts damage. Troubleshooting methods:
1.Disassemble damaged parts of diesel engine, replace damaged parts of diesel engine after washing water radiator and inner waterway of block with fresh water.
2, after assembly, adjustment, test machine found that the diesel engine returned to normal, the fault was eliminated.

1: Check if the alarm is stopped, a, low oil pressure b, high water temperature c, overspeed, etc.;

2: Check if it is overloaded, whether the inlet and outlet pipes are unblocked

3: Check if the parts are broken or loose, and check if the fuel tank is short of oil.

4: Check if the fuel injection pump is damaged

5: Check the speed sensor, electronic speed control board, actuator, etc.

You run again the generator but before running, check & mark the oil level. Then stop the generator & wait until the oil settle to the bottom of oil pan. Check the oil level again & if the oil level is higher than the marking before that's means you have an engine gasket leak.You need to replace that gasket.

what safety caused the alarm. if you cant restart it, it may be cause the problem that originally shut the engine down has not been fixed, it could be water level, low oil, high water temp, low fuel,over voltage, all of the above are probably run through the safeties. over volt, and water temp would probably clear its self after it sat a while. try turning off power to panel. for a couple minutes and see if it will reset, if not check water level. and oil levels

Check the fuel solenoid is getting power. It may be locked out by loow lube oil pressure and other things.

ALSO when restarting a diesel one OFTEN must "bleed" the fuel lines at each injector... same as when one inadvertently runs a diesel out of fuel. Crack the connectors at the injectors and crank till fuel comes out and tighten each one. Yes, it is a pain...

Did you have a auto controller?
With the switch set to AUTO, the engine may crank and start at any time without warning. Such automatic starting occurs when utility power source voltage drops below a preset pevent or during the normal exercise cycle. To prevent possible injury that might be caused by such sudden starts, always set the switch to OFF and remove the fuse before work. Ing on or around the generator or transfer switch.

The distance between the sensor and the diesel generator flywheel is too far or too close (generally this distance is approximately 2.5 + 0.3 mm). If the distance is too far, it may not be able to sense the signal. If it is too close, it may damage the working surface of the sensor. Due to the high-speed operation of the flywheel, radial (or axial) turbulence occurs. The distance is too close to pose a great threat to the safety of the sensor. It has been found that several working faces of the probe have been scratched. According to practical experience, the distance is generally about 2mm, which can be measured with a feeler gauge.

If the unit has a battery box, measure it and get the largest size that will fit and of course the correct voltage. Diesels take a lot to crank.

You can search battery sizes on the internet for physical size. NAPA has a pretty good selection.

The controller circuit card needs to be replace. This is
the one that senses if and when power is shut off. This
will automatically start the engines.

Ensure any engine control switch is set to the run position, with the load disengaged. Manually set the air shut off valve (if fitted) to the run position (see Fig. 18), Turn the key switch to the start position, which will energize the solenoid allowing the engine to crank over for a few seconds then start.

Check the instrument panel is showing normal running oil pressure, and the ammeter for charge to the engine batteries.
Allow the engine to run for five minutes checking the instruments are reading correctly. Stop the engine and check the oil and coolant levels, replenish if necessary.

Timing gears? have you pulled it that far apart? On timing gears there are usually stamped onto the gears a small dot. lign them up. Not sure why tore down so far? If you take off the diesel pump align the timing marks in the small window plate first else you will be in a mess.

You have the remote control wires incorrectly connected either at the ATS or on the generator control panel, disconenct from both ends and ohm them to make sure they are not shorted between. Then reconnect them at the generator end only. Then join them together manually, of the gen starts and stops when taken apart, the problem is in the transer switch, or incorrect terminated

Hi ,
firstly i would do a full service on it , all filter and fluids , oil/coolant water,fuel filter(s) and air filters
pay attention to any water seperators , check all fuel line connectors and unions are tight and in good order ( drawing a small amount of air into the fuel system if often the cause of ''a lack of power '')
check your diesel as it absorbs moisture and can severley effect the running of an engine .
if this has no effect
get a rag /goggles and the right size open ended spanner and slacken each fuel injector nut whilst the engine is running , listen for the engine noise going down , if it dosent this means the injector is deffective ( might need replacing or cleaning ) do this to each injector in turn , be very careful as you do this , the diesel is at 200bar pressure and can injected you ( hence the rag )
a final one is the fuel lift pump may be deffective , they often partially work and starve the engine at maximum revs , depending on your engine this will be an electric one or driven directly from the engine block , just follow the fuel lines from your diesel tank ,.
hope this helps
