ELEVATOR TROUBLESHOOTING | Marine Electrician

[@InTransitGaming]

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!

[@leckyjake]

Thank you. It is the satisfaction. I just can't explain that feeling. Safe sailing

[@pedroveloso9707]

kkkkk ohh yes, a few understand well that ..."yeeessss...." ..

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!

[@jackburnell3209]

It must be nice working in an environment where every device is labeled and has a manual.

[@danielelise7348]

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.

[@dwaynes5983]

You always get to the problem logically. Great skills!

[@leckyjake]

Thank you.

[@alexanderkupke920]

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.

[@christhackrsy]

Impressed by your logic and natural ability in your job, if you ever dock in the uk let us know in advance I’ll buy you a beer

[@johncantrell614]

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!🙂

[@KutWrite]

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.

[@bigmedge]

Hi Jake, thank you for providing such a thorough & methodical tutorial !! 3 questions plz sir: 1. @ 4:40, for determining that all the CPs have supply voltages, did you check for voltage by placing the multimeter’s red lead on each CP’s power pin & black lead on a chassis ground ? 2. What was the thought process that led you to make the correct assumption that it’s relay MCA, rather than contactor MC, that’s the faulty component? 3. I understand why you checked for 24v be tween P24 & N24 on either end of that circuit; but from the wiring diagram, it looks like A220 & B220 are on different circuit legs, so why was there 220v between them?

[@TheLusus]

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. 🤜💪

[@dragonfireproductions790]

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

[@jamesmaida47]

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.

[@eyadalsaadi]

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.

[@kem-zq8si]

That relay was reading good, howcome you didn't assume the contactor was bad? maybe some of you other guys can respond, i am curious.

[@alexpornes7182]

Hahhaa happy reaction sir. Napa yes!!! Hahhaa. Kakaba lang ang board or PCB

elevator is like part of the necessities onboard. if you can't fix it, all eyes are on you.

True deck and engine are always eeying on lecky. That's the challenge for a lecky.

[@jiouse5881]

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.

[@akshayrathore5673]

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 ?

[@michaelardai9703]

P24/N24 power the relay coil. The contacts are on the 220v side and pull in the MC contactor

[@leckyjake]

Thanks

[@unobono]

@@michaelardai9703still cannot understand. Shouldn't it be zero between p24 and n24 because the relay is activated?

[@keything8487]

we usually tap on relays to see if they engage.......good video

[@jesonabejuela3737]

Slamat po sir Sa video, marami akong natutunan.

[@ivanfmartinezm]

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.

Good video. At 11:53, what are those plugged in items on Magnetic contactors? Thanks.

[@alexanderkupke920]

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.

[@cck1496]

@@alexanderkupke920 Thanks for your kind reply.

[@Viper607706]

I'm confused. When you showed the n24 and m24, it displayed nearly 26v, but you stated it had 24v, isnt electrical equipment sensitive to overvoltage?

I find relays being a common issue in industrial applications. Solid state relays seem to be allot more reliable

[@whatevernamegoeshere3644]

Sadly they also offer less isolation as they are not galvanically isolated when off so the number of possible applications are tighter

[@alexanderkupke920]

@@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.

[@whatevernamegoeshere3644]

@@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

Lecky sir, salute to you for your magnificent job.

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

If that relay said it was on and had the proper voltage what made u change it and why was it the problem if it was working properly?

Am sure maybe its my misunderstands after interchange the VCB#3 on Genset #4 problem was cleared (NO REVERSE POWER TRIP ON VCB) , Cause of that logic action to open VCB#4 to find out the defective parts. Continues for my first comment on REVERSE POWER AT GENSET#4

[@leckyjake]

That is correct. Hello Eyad, First of all thank you for watching my videos and really appreciate the time. After interchanging, no more nuisance reverse power trip happen and the Generator can be put on loas using the other VCB hence there is no problem on the curcuit side of the Generator that is why I focused in opening the VCB only.

i wonder why the Elevator company did not include a relay test circuit board... to plug relays in.. and test their operation.. did you examine the contacts thru the clear plastic.

[@leckyjake]

I did not check anymore the contacts as the coil is activated but still not activating the MC so I go straight in changing it to make the troubleshooting faster

[@waynep343]

@@leckyjake i can understand that.. but i used to use relays like those. in a project.. i set up a rotary switch with piezo buzzer.. so i could close the relay by pushing a button.. with the other hand i rotate thru the contacts and i could hear changes in tone indicating the relay contacts were getting corroded so i could change it out before it totally failed. took me seconds per relay.. kept my project working with only a 10 or 15 minutes of scheduled down time a month to go thru the relay tests.. i did have banana jacks so i could take the piezo out of the circuit and hook in my ohm meter. its just sharing.. i worked on a friends 104' wooden power boat for 22 years.. my cousins are fishermen in the pacific northwest .. i went on their fishing boat while it was in harbor one day.. these guy go out in the gulf of alaska .. the poor workman ship and planning of their electric and hydraulic systems scared me . your going to take this out in 50 foot seas at -50F i went straight to their grand father and had him get involved in getting some of it corrected..
