We have a pramac genset equipped with a AC03 controller and time to time in AUTO mode it changes alone to MANUAL mode. Please, can anyone help? Best regards. FGaspar

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.

Hello. Maybe you have solved your problems. But I still want to share the helpful article to you. https://www.dieselgeneratortech.com/diesel-generators/why-diesel-generator-fail-to-start.html

We are Perkins diesel generator OEM. Can provide 22KW to 2200KW diesel generator set with Perkins engine. https://www.dieselgeneratortech.com/perkins

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

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.

Hi, Something is wrong with the govener (stuck or bent). Look to see for obstruction when you crank the throttle. Or maybe a better spring on it.
Good luck

Start looking at your safety circuits.

1. High water temp
2. Low Oil
3. Low water etc...

From the manual these are the protection circuits.

• Engine protection: low oil pressure, high engine temperature.
• Genset protection: under/over voltage, overload, battery charger failure, battery voltage out of limits,
under/over frequency, start failure.
• Circuit breaker protection: IV poles.
• Differential protection.


Any one of them will trip the fuel relay closed. What you may be able to do is disconnect one at a time each protection circuit and see when the fuel relay opens. (Make sure to reconnect each one if it had no effect on the fuel solenoid)

Once you isolate which circuit it is in then you can chase wires or change the bad switch.

Thanks for choosing FixYa.

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.

my 500 kva diesel generetors dosnt work since mornning its workes after 4 houres when the weather changed

My answer:

Not much in your original ? to go by as far as any history background of the Genset - if it indeed is a Powermate? Is it? And if so - is it already USED or is it BRAND NEW right out of the box - like many others here who I've already helped out and solved their problem(s)?

If this Genset is USED how many hours are on it. Try to be as accurate as you can - if known? Also - If this is not YOUR originally purchased Genset, but rather bought 2nd hand - did it work right when you first bought it?

Is so BRAND NEW or even USED - then I minds well tell you this first (if you don't already know this). After which I have some tech troubleshooting ??'s I need answered so I can pinpoint the problem.


As you are now hopefully but painfully aware - Powermate has gone totally Bankrupt, and is no longer in business as of this past year or so.

There is hope though - as I state below in the previous Footnote I posted to many having similar problems.

Previous Footnote: It's too late now for all those out there that unfortunately bought these now still Brand New "unserviceable" Powermate units that won't start for whatever, whether still Brand New "NIB", or whether taken out of the box and still not used, and are now seeking some kind of service on them (btw it's a sign of the present day GOP ran economic woes we are in AND it will only get worse - CHINA is going on the very same downward skid right now thanks to you know who - W!). If you buy anything today "made in China" - esp their cheap knockoff Gensets - you better be making a GOOD buying decision - otherwise you will be in the very same situation you are in now with your Powermate Gensets - as China is starting to collapse from within just like this USA economy of ours has been doing for the last 5-6 years to no end! All politics aside as well - as blame is put where it is deserved in my books and we can only blame YOU KNOW WHO! Sorry but true!

NOW -

Any inventory stock of their (Powermate) Gensets - that were once formerly sold in the USA & Canada - have been totally liquidated out to a company in Georgia I was told, and it was said to be true.

I was able to get this NEW added info through another source said to be VERY accurate btw - so hopefully it is.

BUT -

Before you blame me for any possible incorrect Powermate info posted above in regards to that PRAMAC Co, or their contact info - read the GOOD NEWS below first, unless the BRAND NEW part doesn't apply to you here.

The GOOD NEWS is that I spoke with a very close contact inside Home Depot (not saying who so don't even ask), and that person gave me some very GOOD NEWS for those that act on it NOW!

Not tomorrow - Not next week - Not next month - and certainly NOT NEXT YEAR!

DO IT RIGHT NOW!!

I spoke with my Home Depot Corp contact today (using your "not starting" dilemma - as my own - to get a response) to see if anything could be done from their point of view and here's what I was told to do.

What I was told is that if I (you) bring in my (your) ORIGINAL HOME DEPOT CASH REGISTER DATED RECEIPT and speak to the (whichever Home Depot store applies here) Home Depot Store Manager there, and explain to them that the brand new never used Powermate Genset they sold me (you in this case) won't start - they would send your Genset out to their local Genset Service Vendor FREE OF CHARGE BTW, and hopefully get it started for you.

Anything more then that - you would be on your own if it was damaged by you or someone else that tried using it improperly.


NOW - as for your Genset there and the OVER-VOLTAGE condition you say you are experiencing.

I guess my first ? is - Which volt meter are you reading?

The one on your Genset possibly, or from a known Good Quality & good working hand-held DVM meter? If your AC panel meter is defective then that is not going to help matters at all. If your Genset control board is shot most likely something caused that condition from an electrical/electronics standpoint either on the board itself inside the "front panel control box" or else inside the "Gennie power head".

Usually an OVER-VOLTAGE condition occurs when a modification has been done to the Genset, such as say a new (or possibly a bigger wattage) replacement "Gennie power head" that is not rated properly to your engine speed (which btw should be ~ 3600 RPM max). Did you make any such modifications to your stock Genset recently?

If not - then we need to make sure you are getting the proper AC output measurements using a known good DVM meter set to the AC scale and either on 400 or 1000 volts depending on your meter's settings. Hopefully you're not using one of those defunct $3 cheapy Harbor Freight Tools meters either?

With the Genset running at normal idle what voltages are you reading at the 120VAC & the 240VAC outlets - from HOT to NEUTRAL only? Low - High - Sporadic - what? Be precise here - very important!

If you increase the Genset speed up to 1/2 Load speed what voltages are you now reading as well? Try not to run at Full Speed if indeed something had smoked inside the Control Panel such as the Control Board. Check that board out first for signs of damage. Does it look OK?

If this Genset has had HIGH HOURS of run-time on it have you check the "brushes" and/or "slip rings" on the ROTOR it as of yet? If it has brushes are they within factory spec? Are the SLIP RINGS clean and not arched and dirty looking? If the latter is found to be true then the SLIP RINGS need to be cleaned and polished bright again!! Very important!!

If the end plate (cover plate) is taken off (if you feel capable to do this yourself) is the inside fairly clean inside and around the SLIP RINGS & BRUSHES area? Do you smell any BURNT smell inside? If so then possibly either the STATOR or the ROTOR has gone bad! If not take an air hose and thoroughly blow out all the carbon dust & dirt and replace the "end plate" securely.

Unless it's a BRUSHLESS type Genset you have (which I doubt) then the problem possibly lies within the "power head".

Let me know what you find now that you know what to look for?

Based on that we can look still further is it's not covered above.

Best regards to all with the same problems, and hope I helped you out 100% - all political humor/truth aside.

Please post me a reply as to finding this solution being the best resolve to your Powermate problem there by following my recommendations above. Also please rate my troubleshooting fix as well.

Keep me posted and I'll follow up as well.

Best regards,

Frank

My answer:

Hello Gary,

Well - I guess you too are one in a long list of people that bought these Powermate Gensets from Home Depot and first now - WOW - after 4 years in the box you are first firing it up. 2 years in the box would be bad enough, but 4 years boxed could have even more gasket, etc related problems even more! Never know with these cheaper Made in China Gensets these days.

So - where to start on yours?

I guess I better tell you what I've already told others in your same situation unless you already know what I'm going to tell you.

I'll repost a shortened section below for you to read first as you have NO warranty option at this point, but might have a Home Depot option as you read the following below - after which I'll run through some common problems as it seems you already have the most common problem covered - as to adding the proper type and level of oil before you do anything to start the Genset - being careful NOT to over-fill the oil sump.


FOLLOW-UP ON ALL POWERMATE GENSETS

A follow-up to my original post here with some added Powermate info that hopefully will get you an Operator's Manual, service for your Genset, and more - for all your Powermate Gensets out there if you follow-up on the info here.

As you are now hopefully but painfully aware - Powermate has gone totally Bankrupt, and is no longer in business as of this past year or so.

There is hope though - as I state below in the previous Footnote I posted to many having similar problems.

Previous Footnote: It's too late now for all those out there that unfortunately bought these now still Brand New "unservicealbe" Powermate units that won't start for whatever, whether still Brand New "NIB", or whether taken out of the box and still not used, and are now seeking some kind of service on them (btw it's a sign of the present day GOP ran economic woes we are in AND it will only get worse - CHINA is going on the very same downward path right now thanks to you know who - W!).

Anything more then that - you would be on your own if it was damaged by you or someone else that tried using it improperly.

Here's another IMPORTANT FACT my contact at Home Depot told me.

Almost 95% of all the Genset problems found by the Service Center are related to the fact that people don't read the OWNERS MANUAL first, and just didn't put OIL in the Genset - as they are shipped from the MFR without OIL in the units to begin with!!!!

And here I thought everybody KNEW THAT!!

I guess sometimes you just have to ask the most OBVIOUS ??'s first huh (dumb as " it " may sound)?

If you bought your Powermate Genset from other then a Home Depot Store then you will have to contact that outlet and see what they have to say.

Some other obvious things to look for that may be the cause of a NO start condition even after adding proper gas & oil to the brand new Genset.

1 - Some Genset gas tanks come with a gas cap "blocking insert" under the gas cap that should be removed according to your manual if it states this. (Read manual section on "First Time Starting")

2 - Is the gas tank shutoff valve FULLY OPEN?

3 - Is the RUN SWITCH set to ON or RUN position (this is purely an "Electrical Switch" btw)? Is it working properly? Test it using an DVM or OHM meter! It's contacts may have become tarnished just from sitting so long?

3 - Is the choke being set to the proper position with or without using Ether spray to the Carb?

4 - Does the Carb have a Yellow or Black wire coming off of the bottom of the Float Bowl? This goes to the GAS CUT OFF SOLENOID mounted in the Main Jet inside the Float Bowl. NEVER CUT THIS WIRE as some people have suggested, as there are better ways to test the solenoid without doing that! If equipped with one - This anti-dieseling solenoid has to work properly or else flooding will occur with the gas shutoff valve OPEN.

5 - Is the Float stuck in the CLOSED position not letting gas into the Main Jet? You might try and tap carefully on the bottom or side of the Float Bowl with a hard rubber hammer first to try and see if you can dislodge the stuck Float inside. If there is a WIRE at the bottom of the Float Bowl on your model - DO NOT HIT THAT GAS SHUT-OFF SOLENOID WITH THE RUBBER HAMMER - as you will do damage to it! If this dislodges the stuck Float then your problem is solved! NEVER FORCE ANYTHING!! It's possibly that you might have to loosen the Float Bowl slightly to see if indeed gas is getting inside to the Float at all. If gas comes out readily but still no gas is getting into the Main Jet and intake then you purely have a Carb issue and nothing more! If you're not smelling gas through the air filter box then you are FUEL STARVED.

6 - As dumb as this next ? is to ask I have to ask anyway - Are you getting GOOD spark at the spark plug? Some units ship with the spark wire cap disconnected and it may look like it's on the plug, but in reality it really isn't fully connected!

That's about all there is unless you got a Defective Genset from the start. Next stop - Home Depot!
