Hi,
As this image shows this CAT 312BL machine with serial number 9FS00946 shows these alert lights even after engine is started.
After starting the engine, bottom 03 alert indications & charge alert indicator should be turned off if these fluid levels ok and relevant sensors, ecu ,monitor, alternator & wiring lines fine.
( coolant level, engine oil level & hydraulic oil level alerts)
After starting this machine within first 05 minutes of high idling then alert indication for engine oil pressure comes on with the alarm buzzer and stays with the warning light flashing and alarm buzzing.
it takes about 2,3 minutes to comes on [alert indicator and alarm buzzer] after starting the engine
& at first this warning comes intermittently and after little while this stays continuously. All this thing happens with in first 05 minutes after starting.
As operator says he has worked with these warning lights and alarm buzzer for about 1.5 hour until it automatically stops the engine. And he has started it again at that moment and immediately all the alert indicators above mentioned have illuminated again. but engine oil pressure alert and buzzer have turned on quicker than the earlier as above mentioned.
As he said now that the engine automatically stops with these conditions with in about 15-20 minutes of work.
I told him that not to run the machine any more with these issues until solve it.
1.Which of these 05 alert indicators responsible to turn off the engine for safety in combination with the ecu ?
2.If engine shuts off due to one of these indications, how long will it takes to turn off the engine ?
3.I would like to know your ideas about that why engine oil pressure warning comes on like this and reasons for engine shutdown?
I think this oil pressure warning can come up because of a bad pressure switch, low engine oil pressure due to various engine issues( bearing leakings etc.), a wiring issue or ecu fault.
I did not check any thing until now ( fault codes, engine oil pressure using a gauge, senders conditions, supply voltages, wiring, etc. ) because machine is working at little far from where i live.
4.Could this be a something else because of all these alerts comes on at the same time ?
So if you have any ideas it will be helpful to me.
Thank you.
