I'm still learning my set up....this video is very helpful
My set up if to automate a generator remote start.....
I have a power station built into my utility truck, everything runs off a battery bank, climate control for electronics, and even the cab.....vehicle security, and anything I may add in the future....
The System recharges the battery bank with solar, and when the vehicle is running, but on cloudy days, when the vehicle sits, it needs another option....
So I've given the system the ability through a pair of mechanical "fingers" to push the start and stop button on a generator remote that is directly powering a large battery charger.....
So from your video, I will be wiring A1 to the "Permissions System" which consist of 3 individual Permissions, first, a 12 volt timer allows power from 7am to 5pm 7 days a week.....second, if the vehicle is driving, which isn't really necessary, since it has two dc to dc chargers, one each for logic, and power battery banks wired into the alternator.....third is an override switch, incase the vehicle is going to be sitting for a while, and generator noise isn't an issue....
I'm going to use the "S" switch terminal to trigger the two relays....
When the generator is running, a simple 12 volt adapter will send a signal to a dedicated hour timer relay, that will send a signal to delay 10 minutes, then press and hold the stop button for 3 seconds.
The 10 minute delay is to give time for the engine to stop.....which will cancel the "stop signal" from repeating.
A Voltage Monitoring relay, if it drops below my set voltage, will send a trigger signal to delay 10 minutes, push and hold the start button for 3 seconds and delay for 10 minutes.....
This will give the engine time to start, and begin making 120 volts of electricity to the charger, and the 12 volt adapter, which will start the 1 hour timer, and cancel the "Low Voltage" request.
After one hour, the generator is shut off via the remote....
Now of course, I always make things more creatively complicated....just how I think.
So two battery banks will be sharing this generator starter.....so both have Voltage monitoring relays, so if the logic battery bank needs a recharge, it starts the generator.....BUT!!!!....both battery banks will have access to a N/C solenoid connected to the opposite battery bank.....in other words, while the logic battery bank is charging, the main cable to the power battery bank will be disconnected, and vice versa, so whichever bank called for recharging, gets a full hour (the charger automatically stops charging when batteries are charged completely, even if the generator is still running).
So the second battery bank will be "on hold" until the hour is up, and the 10 minute delay between stop and start.
So at this point, as long as I keep fuel in the generator.....the system is completely autonomous, with no human assistance needed. 😃👍
Martin, thumbs down my arse! This video/tutorial is spectacular. The demos directly after the sheet review are spot on.
Thank you for the detailed explanation!
I got an OMRON timer but it's quit similar.
Both me and my electrician didn't know how to make it work the way we want it, now with your video it's clear!
חיבור טיימר חשמלי
Your video is great, I am using two of these to literally push buttons on a generator remote.....Your video clearly explains what I need to double check in my settings
Thank
Your presentation was good, my first encounter with this device was in an exam and I did not know hell how to wired it, but now if I had to resit that exam, Ican do it with confident. Thanks to you.
Thanks for your valuable video on Timer Rely. I have one similar that I was trying to energize through a micro switch. You were very helpful in my initial hook up and trouble shoot. Thank you very much!
Thank you so much. Those diagrams are cryptic to decipher and your content did wonders to help in that direction. In my case I need the on/off delay using it on a towel warmer that I want it to stay on when I flip the switch for a set period of time and then switch off again. To be honest, my electrician did not have a clue of such multifunction relays even existed.
Great explanation of how the diagrams work
Can't have any better explaination than this.thankyou very much.
I use those multifunctional ON Delay OFF Delay Timers all the time at work. They come in handy for a wide range of tasks be it for switching conveyors on and off or to delay a function from turning on until after a signal is confirmed to be on for a certain period of time.
Thank you for the great video. This is the first time I've used one of these and was confused by the instructions.
Very good explanation of the functionality. Thanks
Thank you very much for the clear explanation, you really helped me to make the full use of these multifunction relay.
I appreciate your putting in the time and effort it must have taken to bring this all together. I never understood how versatile these devices were until seeing your video even though I’ve read the descriptions given by sellers on Amazon. The features of ac or dc input and output as well as the delay start are just what I’ve been looking for. Thanks a lot.
Function G is exactly what I am looking for- lol. I have been thinking I'd have to use a full PLC. I am looking to trigger an electro/mechanical diaphragm valve as a pulse jet for a bag house dust filtration- self cleaning mech. I believe I'll have to stack 2 so that I can adjust the on time. But I'll use the 0.5s to trigger the second relay. Thank you so much for taking the time to make this video. I'm always amazed at the wealth of knowledge that is shared on here- and how remarkedly easy it is to find.
I found this very interesting and I may have use for it !!!
Thank you so much Sir for your amazingly explained tutorial,
it was really informative
Super explanation. Thanks for aiming your content so novices can follow easily and not assume anything.
Nice explaination in simplest way!
Great video and extremely informative! An application for the 'G' mode that is relevant to what I would use it for in industrial maintenance would be for a dust collection system. We would use it connected to an air solenoid and other relays and contactors to use compressed air to pulse back into the system to blow the dust or debris off off the filters to prevent build up. Extremely useful if you have a very dusty or dirty process and helps extend the life of your filters. Keep up the good work good sir!
Very interesting explanation. Learnt a lot. Thank you Sir
that relay is a nice piece of kit my friend.
Fantastic , this really helped me understand those opaque charts for each function of the timer . I don't have the same model but it helped as a primer to understand the charts on the data sheet for mine (Omron H3DK-M2)
Thanks helped me complete my first control box
Thank You so much. I appreciate the methodical explanation
Thank you for these vedio i learned how to setting my timing relay
Thank you for the info and posting , perhaps you may want to install a contactor on the switched side of your timer relay that can handle the amps of your well pump. This device is quite a toy for any engineer. I used one for my well also, since the well went dry after pumping for about a minute, I would pump for 45 seconds, then shut down for 30 minutes , then repeat. This went into a large 50 gallon chlorinated tank at atmospheric pressure which then had another pump on it to feed the home. Always had water thanks partly to this little device.
Expellant effort toward instruction of relay
Very nice explanation.. It is good for beginners to understand. Thanks for your service. God bless
Finally found a complete video on on of delay timer, today i installed a on of delay relay in engine circuit and couldn't figure out why it was not starting .... but not everything is clear,thanx sir.
You nailed it my guy, this is just very understandable.
Very good information. Thank you for reviewing these switches. It's been 20+ years since last time I designed a control panel for a packaging machine and now I need to create another panel. Question? Is there a reason not to use a motor contactor for the pump?
Cheers mate youve helped me understand this. Engineers make this stuff clear as mud.
Very useful piece of automation... Thanks for sharing
Thanks a lot for detailed information how does timer relay work.
This is EXACTLY what I was looking for and I did find it interesting, great job on breaking down each function. However, my pump is also a 1/2 HP 120 volt unit so I would need to use the other device you mentioned in your video. Can you provide a link for the Relay you used? Thanks!
Love it!!
I made the same mistake with the wiring.
Hours and hours lost.
I am so lucky I am good looking as I am not very bright.
I am using a totally different timer Finder 84C but the same wiring problem
Excellent presentation as usual. I would suggest that the “G” setting might be useful for pressurisation units on, for example central heating systems. The system may be pressure stable and therefore not trigger the pump for extended periods; however it is necessary to pulse the pump to prevent seizure.
very good , thank you for your explanation
Pulse generator is for power on delay, you use it to apply power to a circuit, and then, after the delay period, it either does a reset of the mechanical system, or sets the machine to a defined state. Often used so when power is applied, there is a short delay before the machine gets power applied. For things like a large fan, power on, then a delay before the pulse sets a latching contactor to power on the fan, and then it runs while power is applied, allowing the overload relays on the contactor output to operate in case of phase loss or overcurrent, and then you can press stop if needed, or just cut the power. Saves wear on the main power switch from having to make the large motor load, and also allows transients to settle if the power comes back on after a mains failure.
Liked, subscribed. Good detail, in explanations!
Excellent video, highly apriciate, just one question if you can provide me with an answer, can I connect a PNP induction sensor directly to this specific time delay relay _ and if you can give an indication how to do the wiring? I would be grateful.
Very educative thanks a lot sir...
Amazing video much thanks
have to give it a thumbs up...lol nice video --planning on controlling glow plug timing on a marine diesel...
can you please make a similar video about how phase sequence relay work
Great video, thanks.
This is a good job
Scintillating or not, this video was EXACTLY what I was looking for. Thank you sir for posting it!
A friend has a chiller and he wants to be able to turn this machine on and running via an automation app and some cheap smart plugs. I soldered onto the display board start button and run button. It is a momentary connection so this relay will complete the parts I need. I think it will either operate in one shot or G. I only need 1 pulse in normally open, This will simulate a finger push of start, one more relay to simulate the run function. Love the info!!!
Was very useful for me, thank you, Thumbs up )
HI thanks for this video. I have another issue with my well if you could please let me know that would be awesome. My well's pump pressure switch shuts off due to low pressure I need a relay to turn it back on after 5 min. What can I do to do that? Right now I have to go down and manually trip the pressure switch to turn on. Please let me know really appreciate it. thanks.
Does a simple timer really work? I would imagine it is possible to get a leak that is slower than pump capacity. The pump would turn off momentarily and reset the timer. This is what happens if I leave a faucet fully open in my house. The leak would have to be massive to prevent pressure rise in the tank.
You are a life saver. I have 3 of these damn things thinking I keep getting duds, they need to work on that wiring diagram. What you have to do wire it in isn't remotely evidenced in there.
Could I use one of these for continuous loop say off for 1min then on for 10sec and repeat indefinitely?
Thank you
Tks millions
Nice video! Can that be used for a dumbwaiter?
thank you
well done ,, thanks >>>> continue......
Very interesting
How to install of twin omron timer.. to mechanism..thanks for your ans.
I appreciate what you are trying to achieve but why wouldn't you use hi/lo water level switches?
I have a well that's 480 feet deep and is a low yield well. I can only pump it for about 30 minutes every 3 hours and desperately need a timer that I can simply press a button and have it run for 30 minutes then automatically shut off. Would you have any recommendations? As a note it's 240v and about 1hp.
Im building a Oxygen system for my Glass Shop.. Perfect tool for delaying the compressors and I can use the signal from the OEM pressure switch to feed the timer signal and a separate power supply for the load....Just what I needed to know.
Can I have timer on for 10 seconds and Off for 50 seconds? Or only equal time off and on?
In Europe, practically every major supplier of electrical installation material has a large selection of such timers in its delivery program. And even Chinese companies start to selling this.
They are widely used e.g. for illumination of staircases. Energy costs here promote these timers.
My application is 230V, 10A, I want R to start 10 sec after I switch off U, then R shall run for 10-15 sec before shutdown. Can U help?
Can you switch with a negative?
Thx
Hi.
Is this timer solid state ?
Good
You can use the switch output of the timer to pull in a contractor for the pump .
Yes indeed. That's how I use these to power up a 25-hp irrigation pump -- I use 2 timers in series that energizes the contactor to run the pump 4-hours per day. The timers save me the time of having to traveling 1/4 mile down a very steep hill to the panel and back to when I used to operate manually.
3/4 HP single phase motor @ 240 volts uses 6.9 Amps when running. Just googled this info out of curiosity.
thankssssss
You need a contractor with this
could even drive a contactor with the relay you show here
Would be useful in a wye delta starter.
great little video, not sure what for but i need one of those now lol, except for what they are they're kinda expensive to just have kicking around to play with, amusing reverse psychology with with the thumbs, but would be way more amusing to those in the know if you didnt explain it all the way lol any how thanks for the vid, and the product, hope i remember it when I actually need one.
Can you make it with magnetic relay and overload relay
Sure you can -- I use these to power my 25-hp irrigation pump. I use 2 timers in series that energizes the contactor to run the pump 4-hours per day. The timers save me the time of having to traveling 1/4 mile down a very steep hill to the panel and back to when I used to operate manually.
Does anyone else hear that red led? I cant hear it every time , but at least about 20min spot I can. I suppose it is whining from power supply. Nice video!
Very interesting, of course.
👍
OMG I cant believe with a channel like this you wouldnt just build one with a arduino or 555 circuit opto isolator mosfet massive contactor
18:15 how to dupe the abs light in youre car so the safety inspector thinks youre abs is working.
Well pumps with control boxes have start and run circuits. I dont know why they wouldnt include this very situation with the control box? I dont think its special --saying that you want to stop flow after a time you feel may be in error....a good problem to solve..... Its not like you to get the specs ..mm incorrect..its always lollol funner :)
triggered cause its not exactly on .3
No practicals on the connections
