No alarm on the control panel and the elevator is not operational. How will you start the troubleshooting? Here is my simple and conventional way of fault finding.
The moment you walked back into the lift room and saw the motor turn over - That is ETO candy. The feeling of fixing the problem is why I love this profession. Nice fix!
As a Elevator Troubleshooting Technician, it's like a drug. You get addicted to it. It's weird because you start looking forward to breakdowns like these!
I like your methodical approach to fault finding,I see a lot of guys just panic & say "lets try this,lets try that"just slow down & work through it.Another one in the bag,good job.
Very cool, videos like this are my favorite. You identify an issue, investigate possible causes, test following schematics and solve the problem. I just found your channel in the last week or so and I watch evey video of yours that pops up.
Sticky relays are so common. 🤣 First thing to do is to tapp on it lighty with a screwdriver handle to unstick it. Or just manually bridge the terminals for elevator call to be able to hear if the relay clicks when it powers on. 🙂 Best wishes, a Swedish Marine electrician. 🤜💪
I'm an electrician but not a marine one. I use the F*ck stick(a screwdriver) and slap the relay. I call it the f*ck stick because you'll swear like hell on one if you get frustrated
I am working in IT, but for the logical approach of troubleshooting I am indeed considering recommending this to some colleagues who seem to completely miss any logical or structured approach to diagnosis and troubleshooting.
Very good man. You are the best! I am a electrician trainee in a maersk vessel in Brazil . But the company called Aliança ( from a group of maersk). I am a problem f22 in a similar elevator.
Hello Mr. Leckyjake, First of all my name is Eyad, am working as electrical engr. (earlier as marine side and recently on electro mechanic Contractor). really appreciated your effort for proficiently on troubleshooting as well as your videoed explanation. i have some clarifications and very important to understand and need your reply once you are free for that. i will start with your video on Reverse Power Trip on Genset#4 and your act by replacing VCB#3 instead VCB#4 and vise versa after RUN genset#4 (with health VCB#3) founded same problem (reverse power trip VCB) occurred again so your solving problem by opening VCB#4 (ITS NOT UNDERSTOOD FOR ME) as I assumed if still revers power activate even with other VCB SURELY its NOT DUE TO VCB AT ALL , AND COULD BE FROM GENSET SIDE. sorry for long message but really i would like to know the correct . ALL RESPECTFUL FOR YOU AND YOUR FAMILY.
Yup, there are times that in troubleshooting, I also call it “chasing the rabbit”, that you have a hard time catching it. But after spending sometimes a long time trying and finally getting the problem, or “catching” the rabbit, that feeling you get afterwards is the reward for all the hard work spent tracking it down. Good video, thanks for sharing!🙂
I just had that feeling with my #1 computer at home. My external backup drive for odd months was intermittent - hardest problem to fix. Switched drives, then power supplies (which never break). Of course it worked as long as it sat idle. Mid-backup (2 hour job) it would fail, and... yes... it was the power supply (wall wart). I didn't have that voltage as a spare from my parts box. I had to order one, so I ordered two to have a spare. Four days later with a new PS, it worky-worky! Yay! I also get that feeling when solving software problems, which even occur on my Linux system... usually after a major update.
This was a great shared experiences ,if you are able to make more videos from this content I would be verry thankful and not only me I think! Keep develop you account.
Lecky sir, salute to you for your magnificent job. I just request you to put some videos of boiler troubleshooting, coz I had problems in calibrating sipart as aux boiler was not firing and giving air servo error although dp transmitter was giving 4-20mA signal. Another common problem is boiler water level control is not operating in auto as feed water valve is defective, despite water controller giving 4-20mA signal,pilot burner toowas not firing due to defective cable. Plz suggest some easy ways of troubleshooting like this, thank u
Very clear and informative. We have installed one local brand elevator in our building. It got damaged by lightning strike and that company is dead now. I am sure that something is wrong in the control board but the wiring are too messy; no label, no colour code or numbering. Beside that no document or service manual. Now I don't know where to start.
Good day sir, we have the same type of elevator, can you share your insight regarding f54 alarm? From my troubleshooting, my locking magnet (retiring cam) is not being energized. The power for LM relay should come from the SIO board. But some conditions I think is not satisfied. Hope you can somehow help me. Thanks and continue to inspire our fellow ETO/Elect.
@@whatevernamegoeshere3644 I assume with relays being mechanical devices and especially in marine or industrial environments that may have to deal with vibration dirt and corrosion (at sea everything will start corroding) you are right. Also relays able to switch a certain amount of current are readily available these days. For anything drawing higher currents a contactor would be used anyways. But I also can imagine that with "older" equipment switching everything over makes economically no sense.
@@alexanderkupke920 Corrosion and vibration might not be a factor at all. It really depends on the relay. There are ones that are completely molded into a solid brick of plastic. Another thing is that you would really not replace those relays with solid state relays. It's 24V DC, so a simple BJT would make a whole lot more sense
I didn't understand how you found the problem???? Electrician never guess only check the voltaje secuence in the contact mca because there are several contact relays for safety or interlock until be activate the main contactor MC, in spite of the coil from the relay you changed was working properly maybe or i suppose the contact was broken so that the circuit was open or interrupted in that point. The only way to be sure why the main relay was not activating is checking in the electric diagram all the contact one by one in the ladder diagram begin for the main voltage making sure there are voltage present from the one contact till the last, each one involve in the start secuence of the main contactor MC which is responsible to run the Electrical Motor. Good Job!!!! Amazing i'd like to see in next video a out the frecuency driver from motor or if maybe in that case don't use any only main contactor, because i worked in one elevator with two speed motor directly start.
thanks for your kind attention really appreciated and please go ahead (full ahead not to ASTERN) and good luck for everything and last i excuse for other remarks could i highlighted ? thanks for everything and good luck
jack i have a doubt, at 7:24 when u r checking relay MCA , if the relay is working properly and we measure voltage across P24 and N24 shouldn't the voltage reading be zero ? what i mean is since we are getting 24Vdc(26 in ur case) doesn't that indicate the that circuit is open somewhere ?
I am not entirely sure about those specific ones, but I think those might be monitoring switches to actually check the physical position of the contactor being opened or closed. I have seen similar things for either monitoring and alarm systems, or just if you wanted to logically couple a contactor state with a low voltage (e.g. 24 V) control circuit without adding a relay in parallel.
wow i was not expecting so many control boards for a single lift(one electronic, 2 relay boards), ¿why so complicated?, plus all ancient DIP packages, looks like a 1990's controller, is the ship that old?
From what I know ships do not have a spare of everything. But they carry quite a lot of spares. Of course the more critical a system is, the higher are the chances for spares being on board or the system even has a redundant system. (Radio, gps, coffee maker,...) Also for certain components if possible the shipbuilders usually try to use common modules, so a spare would work in a number of places.
