How to troubleshoot low voltage in generators benzblogs 

As you to coz your you the best tutorial ved.

Thank you sir bless you

Thank u sir

What you mean culprits sir

'culprit' here refers to the potential undervoltage cause

Bless u bro

Bless u too

Welcome air bless u

Yea boss marami tanong lang kong my itanong no prob sasagutin natin sa mkakaaya ko salmat

Bless you too

Thank you

I dont have im alone and only make breaktime coz duty time no allowed

Verry defecult

Sir im in vacation ahm if the problrm underfrenq. Take a look first is the alarm shows with load or without load now if the alarm shows without load just simply adjust the frequency accordingly to the freq.50/60 hz and also check first whin the engine start if there is voltage ok sir

Oo sir medyo expinsive lang sa bahay

No problem there is two vedio about it check the other one

Sir I have checked but couldn't find any videos related to it in your page, thank you​@@benzblogsVlogs

Yes brother

Bro before what is the nominal voltage before not drop first run without load if voltage is in normal if not check the exciter winding if have resistance thin check the diod if in good condation now if all good thin replace avr

thank you brother 👍

@@sultanalsubaie7377 your welcom brother

thank you today I have checked generator and found one cable not attached to AVR, after I connect cable voltage become normal.

Do this first start and check the rpm if stable after that if stable thin check the avr volatge fuses use multi meter to do that if volatge is zero or have 50-vac thin just excite it

@@benzblogsVlogs thank You do much for the quick answer You are saving lifes. I forgot to Say that mantainance team change the batteries with other that migh have a lower amp. That can be a reason too? Thanks again for all this videos !!!!

Only crank not run

@@benzblogsVlogs yes it only Crank it's not really running

Oo pre marami talaga

@@benzblogsVlogs ayus diay kaayo ana ba 😍

Ok tool kit ay ginagamit lamang para electronics engine meron suang tinatawag sabihin na nating block box or ecm yan jan natinmagagamit pang program ant pang troubleshoot ang toolkit

Yes sir

@@benzblogsVlogs thanks kabayan!may fuse b ang avr?anu prblima bigla mag warning voltage down tas shutdown

Sir lahat naman ng manual every engine anjan yunv sensor anong pary saan makikita

@@benzblogsVlogs salamat sa Tugon sir.

Meaning this is 3phase do one thing make a reaistance test every coil but in order to know remove first the connection mostly voltage unbalance is coil problem

@@benzblogsVlogs You're possibly or i can say your correct Sir as we measure different readings on our insulation test. Thank you for your support Sir. More power to your channel.

Sir check mona diode mo kong ayaw mgbuild ng 220

Sir nag palit kana ba ng thermostat?

Sir pano ang checking mo pra masure natin kong mag overhit ba ang engine or ang sensor lang ang faulty

If not start mean there is other problem

Check the fuel bleed it while crank after fuel bleeding it will start

Either ct connection wrong and voltage sensing wrong

Yes sir have a good day there is volatge but no current show ?

Ok new exciter rewind what you mean but still no volatge output is that xorrect?

If its buildup thin replace the avr

Just remove the power supply or the battery to reset juat split seconds

Afyer that crank 3time before start

Ganon padin po master

Check gamit k Ng diagnostic tool para ma identify mo Yung engine problem

Sir mosta man diha now lang nko nkita imo comment

This breaker over current

Check you load and check the the engine if in stable

@@benzblogsVlogs it's checked without load brother

@@samuelgetachew2013 check your comfiguration and adjust the delay time

@@samuelgetachew2013 and check the full load of your genwrator my be exceed that why its alarm BOC

Sir can you explain it properly if you don’t mind?

Ok there is lots of reason first is the load my be hundred percent load directly or your configuration is went wrong or check the alarm so we can point out what going on!

Run it dont put load or off the breaker if same voltage and frequency ok thin message me

Pweding mali ang sensing connection pwding or mali connection itself

Yes sir perkins adem4

Ok make sure you polarity is correct so we can proceed to the next

Now if you connected correctly positive and nigative to exciter and still give low voltage means ither your exciter is defective or the alternator itself have problem

Double check the resistance of the exciter ,winding ,diode and all posible like grounding check in the winding ok

May ved ka kong pano sya namatay para malaman ko din

Mostly pag ganyan electtonics sya tama nakalebrate nyo pa ng maayus sa prog ng injector

If ayaw gumana lahat to make stop dalawa lang yan cover the airintake or remove the fuel supply from intake line

Ok sir ahm ilang kva sya at anong load meron kayo

facebook.com/groups/1581429425388674/?ref=share message me here this my page im ready to help

175kva, 400v, load 70kw lng Po boss.

Ganiro sir sir tingnan mo yung usok ng engine mo sir maitim ba or maputi ang osok

Medyo puti na Po boss..bka magawan pa Ng paraan,. MSC failure muna bgo sia Ng alarm Ng under voltage. Magalaw ang hrz & rpm..bgo din ang ARv.

Thank you sir no prob

Sir ponta ka sa speed controller hanapin mo doon speed adjust pihiyin mo lang hangang omabut sa rpm Na gusto mo

Kong wala naman need mo ng loptap para e adjust

You need also to ajust the config setpoint of your module accordingly

Yes po taga samin po yan

Taga bacuag man pud ko sir

@@benzblogsVlogs kumpari mi ni sisoy, co-woker me sauna sa klift

If the light if there you can flash

Unliss if your module is not taking power supply not posible

Sir pag over voltage ganito lang gawin mo start mo check ko line to line ang voltage at ano ba ang nominal na nakaprog sa module at check mo din mga fuse

Ho bro

Fail to start sir pwedimg hinangin mgbleed ka sa fuel check ko if my fuel return and thin check duel relay is active during cranking make sure suply is distributed correctly

Ok po fuel system aandar po sya infew second at magshutdown sometime ang alarm nya under voltage sometime fail to start sir pero pag tinanggal mo sa fuel solinoid aandar sya thanks po

Okganito yan check mo oil sensor at sw mo ither jan ang my problema

Sir good day to you sir make aure rpm in a good condation if it is high voltage and the engine is normal just adjaut in your AVR in order to fix the problem

Sir filipino pwedi po tayo magtagalog

Ah ok sir if your engine mechanical or conventional normal that the frequency is 62 hz but if electronic should be 60hz but mean while if you talk about unbalance load you have to refer that to your load connection

Sir check mo yung charging alt mo sir ok normal

@@benzblogsVlogs san ko makikita ang charging Alt sir. Currently naka power up ung genset without load para ma check ko kung sa genset ba o sa load ang problem. DSE 6110 MKll panel

Send me picture

And message me in messanger or whatupp

@@benzblogsVlogs FB na lang sir. Ty

Ok sir pwedi madumihan at dina gagana di sya acuraye and reading and starting voltage nyan is ac 0-2 vac

I have a vedio on that also how toninstall mpu

Ok undervoltage means voltage its below from nominal voltage now till me what is the output of the voltage and make sure all the fuse from your sensing line is all in good condation

Double check all the fuse from sensing line going to the module and from your avr ok

The technician checked it sir today and said that the AVR is defective.

Ahm to make first use multi meter to measure each line before the breaker if the voltage same thin check you rotor diode defective

@@benzblogsVlogs tnx

Nong ng excite ka gomamit kaba ng multimter para sukatin ang boltahi or doon kalang ng check sa module? Answer first para maidentify ang prob thank you

@@benzblogsVlogs nag produced sya ng voltage nung binaligtad ko ung postive at negative ng excitor sa avr, tapos binalik ko sa original position. Nag produced na sya ng 400V, kaya nagtaka ako bakit ganun, eh original connection nya un since nabili ng company namin ung gen.set. ngaun po, nag synchronized ako at amg load umabot sa 390A which is balance naman sa ibang gen.set. yung nag increasr ng load, pumutok ung fuse ng AVR. Ano kaya problema?? Pangalawang beses na un na pumutok fuse. Ok naman mga wiring walang grounded, pati excitor ok din. Posible kaya na low insulation na ung alternator windings? Mainit din ung body ng alternator

@@agent70vids3kong ganon medyo may problima na fiose but dipa sya sira

@@agent70vids3 pwedi pa syang magamit ok lamg yan

@@benzblogsVlogs posibly po ba mangyari un na binaligtaf ung exciter saka lang sya nag produce ng 400V, tapos binalik sa dati position ung terminal ng excitor, Ok na sya. Un lang, ung tumaas ung load, pumutok ulit ung fuse ng avr

Yes sir what i can help

What the problem with your generator

@@benzblogsVlogs only 26volts output voltage i already check wiring ang all connections including fuse

3 phase the genset shutdown after alarm

Do one think send me the picture of avr

What kva you have

No voltage out put check wingding correct check avr connection correct if all corrext thin message

Yes check mo sa link in senior technician nkita ko previews week or hanapin www.jubailibros.com

@@benzblogsVlogs thankz benz try ko mangutana

Make sure lang sir na sa viltage sensing side is same na voltage nag nababasa mo sa tester doon sa breaker side if parihu thin there wrong with ither program or a wirng problem only

Baka nga sa program boss icheck ko ulit ang parameters non may mga standard rating kaba bro ng program non wala kasi ako ehhh...

Thisbis with or without load

If this happen only with load meaning you have unbalance load that why uts also unbalance your voltage

If you want to make 400volt ac shout be your alternator is 12leads in order to convert the wiring to series Y to prduce the volatge 400but your need to re connect your avr connection and to change to configuration from your module in order to work

Lot of thing to change in order to work propperly

thanks sir

Yes sir but your line to line sir if zero load what voltage?

And how about your line to nutral at zero load what is the voltage sorry late reply im sleeping the time you message me

Ill give you example if your line to line volatge is let see 240v your nutral should be 139v

If you have vedio sir send me or message me in my facebook or my group so i can help you more

Try 1234 or 0000

In the back your module there is sensing and that is connected to your alternator wich is joint with fuse

Some its inside the alternator but mostly is in the panel area if 3phae this is 3fuses

Please sir,we will like to see the where you disconnected the fuses from. A picture or video. Thankyou​@@benzblogsVlogs

Yes no prob

Juat ask no prob bro bless u

Sir i try coz you know company

For now i have training for sync using 8610 dse

Ok sir .venz. Salamat

But i can help you if you have some problem about it

Bless u sir sensya na

Sir high volatge alrm always i ask to check if engine speed if stabel thin check the avr volatge now if all ok at zelo load this. Only config you need after that put over and under voltage delay your prob solve

@@benzblogsVlogs Thank you sir. We will try your suggestions. But if the AVR are faulty, can we replace it with different type of AVR? like a generator set with shunt excitation alternator and a Stamford AS440 AVR to a Stamford MX321 AVR with pmg type of excitation?

Yes you can just follw the instruction how to do it

Bus not live meaning there is no voltage going to your module buss sensing make sure also the the aux contact is working properly for feedback going bact to the module

This happen dur to the load what module you are using

Off tge breaker run the generator adjust the voltage in tge avr using the voltage potentiomter there in the avr use multimeter to measure the voltage if its blance its always have variation 1-2 deferences

Onang tingnan mo is my nakainstall ba young breaker mo na shuntrip if meron nakaprogram yan sa module at may isanag relay yan para sa trip ng breaker mo

Ngayun tingnan mo kong nagtrip ang nreaker ibig sabihin pwedi yan common electrical trip or high current or depwndi sa program ng module mo

Medyo luma na kasi un sir, ndi ko na alam kung nasa ung module nun po, saan po makikita ung shunt

Kung ganun nga sir ang cause, panu ko po sya ulit mapapa takbo ng ma ayaos at maiwasan po ang electrical tripp

Slamat po sir ng marami

Motorized breaker bayan sir

Sorry late reply pagenerator fail to closed sir check monlan aux contac nya kong may binabato pabik sa module

@@benzblogsVlogs Oo nga pala Sir,motorized xa,nka synco pala,kaso d kuna pinagana isa, dahil maliit nlng load,tsaka may sira dn..cge Sir salamat,nka subscribe nko sau Sir hehehe

Salamat sir malaking bagay na sakin yan sr bless u and keep sfe

what happen alarm loading voltage not reached come out

Sir ganito yan loading voltage not reach ano ba ang bolatge ouput na nalabas sa generator mo ngayun kc halimbawa 400 ang ac before ang configuration tapos ngayun ang output lang ay 380 lang hindi inabot you g loading na 400

Check mo ang confige ng module sir makikita mo doon kong ano ang nakalagay na loading volatge

@@benzblogsVlogs sorry sir i can't understand speak filipino?

What you maen sir

Anong klasing alrm

Sir pag overvolage magadjust kalang sa avr mo

Simple sir ponta ka sa avr mo adjust mo doon

Nag-adjust na kami sir pero ganun pa din. Meron pa din Generator Over voltage.

Send mo nga ved para mkita ko anong naguaro

Pasensiya sir pero hindi ko nakunan ng video pero ganun yung pangyayari. Kung baga eh nag bigay siya ng generator over voltage tapos nag adjust kami sa AVR pero ganun pa din alarm na binibigay niya. Hindi kaya sa AVR ang problema?

Ganito mona sir paandarin mo teaterin mo sa module yung voltage sensing ng module if my voltage kong wala check ko fuses kong my busted now kong ok at ganon padin check mo fuse ng avr at kong ok at same walang voltage mg excite kna okay

Thank for concern i do no prob

Ano yun.sir

Pwede po ba kita ma pm sa messenger sir? Papa help po sana ako about sa generator ko po

Sana po matulungan nyo ako sir

Ayaw po kasi mag stop yung engine. At sa panel po nakaindicate na *warn stop fault

No prob sir message me i reply you there

That is what we called loose of magnitism that why whin. U put excitation it return all the magnitism in your winding and its work back to normal

What solution how can I solve it please reply as soon as possible

Do one thing tester your exciter what ohm you get it should be 10-18 0hms thats still good

Of more than that value or no value its faulty already

Sir whole alternator winding value is good condition correct ohms showing but no build up voltage

All my vlogs now no music at all
