we have one of the new katolight gensets, it a natural gas fed generator, 100 kw , 480 3 ph.

it has been cranking and starting at intermittent times, i am reasonably sure the transfer switch is not causing the problems, anyone seen this before?

the transfer switch is the latest ansco switch.

its new and under warranty, the start up tech was just kinda like a cow looking at a new gate:confused:
 
start ckt

start ckt

Must be some sort of short on start terminals maybe crushed pipe or water in pipe. There are many anti grounding fanatics who dont understand control ckts if that crushed pipe is crushed on an ungrounded control ckt your emergency stop ckts wont work so good. try to stop that conveyer belt as it is ripping someones arm off. You got something against cows??
 
Can you run the generator on manual mode ?? if so you have to do some baisc troubleshooting

if it has been cranking and starting at intermittent times, i am reasonably sure the transfer switch is not causing the problems, anyone seen this before?

did you or the installer check the Natrual gas supply to make sure the gas metering device can handle this kind of load ?? that go the same with natural gas piping from the meter to the generator

one of most common cranking and intermentents time typically will be either fuel or ingtion system

you should have at least 7 or 14 inch water colloum for gas pressure depending on which regulater it have from the factory.

also there some generator do have automatic shut down feature if following items

overcranking
low fuel pressure
low votage [ generator battery and chargeing system]
fail to read the rpm
low engine oil pressure [ it will automatically bypass it for first 10 sec or so to get the engine up to the speed ]

those is most common item will cause hard cranking or interment running

but there are few other along the way

did you check the natural gas filter before reguator ? this one of few spots that it will get screwey on this if you pick up some debries along inside the pipe it will get the reguator mess up the same thing with the nozzle port for intake manfold where the natual gas do run into the intake manfold [ if this engine is turbocharged it will be right before the turbocharger intake and check all the rubber hose aka socks and check all the socks are tight and have no way have a leakage during starting

very poor fuel qualinty will do this as well

if this engine was shipped with fuel system set up on LPG gas it will not run right as well it have to recalberated to run on natural gas both have diffrent gas charatics

hope this will cover most common engine realted issuse as long you isolated the transfer switchgear and working propely on that part

there one trick i do once a while spray either [ starting fluid ] to the intake port and see if the engine do run if it do run for few seconds then you have fuel related issuse if not then you have some issuse with ingtion but for most part they are electronic and it should be petty much set up by factory unless soemthing mess up along the way

Merci , Marc

I don't understand how having the circuit grounded would make it work better in the event of conductor damage.

Control ckt

Control ckt

If the control transformer is not grounded and a fault to ground happens on say a stop circuit for a piece of machinery by a forklift crushing a pipe the control ckt wont blow and drop out the motor until it is fixed. if the seriesed stop circuit remains bridged by a damaged pipe the emergency stop circuit will be disabled from the point of the bridge out. This is why it is always important to physically check that the ground is connected on control ckts so if a fault occurs it will blow the control fuse and drop out the equipment.

You got something against cows??

:grin:

mooooo, no, i love cows, they give good milk.

that was a favorite saying of my grandpaw, it's a nother way of saying, he was'nt much help! it the start up tech does not know what to do, he's not much of a tech, you savie?


thanks for the suggestions, since its under warranty first i will watch to see what the contractors do to solve the problem, since it is their problem;)

this genset has the electronic display(digital), :roll:

Ok,I'm at a loss as to why no one thinks the ATS has anything to do with this. The ATS tells the Genset to start.
It sounds like the ATS is seeing a power failure OR a voltage drop that falls under what the ATS is looking for.
Sounds like the Mfgr. needs to get someone in there that knows how to set the parameters of the ATS.
I can't see how anything else other than the ATS is causing this.
Unless,As posted earlier the start circuit is grounded.

the generator cranks for a 2 seconds or 3, then stops, it usually never starts, it just cranks for a couple seconds,

yes, it runs in manual mode....;)
