- Time delay relays are very important in a motor control circuit that requires sequence starting. Utilizing On delay relays allows you to time starts between motors. This video will explain how this is possible.

a well thought out explaination
The auxiliary coil M
How it will hold if it in normally closed ?
I think It will be in open state ?
Very informative. I’m a woodworking guy, and a novice in electrical automation. I am trying to automate my shop vac filter cleaning. I have a 2kw 220V shop vac, and a small 200W motor that runs the filter cleaner. I start and stop the shop vac with a remote controller. Today I run the shop vac filter cleaner manually. I would want to run it automatically with a time delay, such that it starts 5 sec after shut down of shop vac, and runs for 10-15 sec, and then shuts down. This repeats after each time I use the shop vac. Do I need a full set of interlocking contactors, relay and timers to ackomplish my goal? Can you guide me, or better still, could I ask you to create a UA-cam video on this topic, as I am sure I am not the only one struggling with this task.
Greetings to you sir. Great tutorial. Can you do two of this circuit in one so that when one motor stops, the other starts? 3 phase.
Hello Thanks for the video. Can you help me on the following:
I have 2 Air-conditioning units which I don't want to have them turn on (takeoff) at the same time as if that happens the main circuit breaker switch trips. Therefore I need some sort of a delay-On device that receives signals from the two thermostats of the two AC units and then pass them to there assigned magnetic contactors one after the other with a time difference between the two to prevent the units from turning on at the same moment which will lead to MCB tripping.
Waiting for your valuable answer.
Regards,
.
if i remove the contact M and keep the timer will the timer still count 5 seconds if i press for 1 sec i will be left with 4 seconds or will it restart waiting for a continuous 5 seconds
Dont you need a cr1 to hold the start in place? Or does the time relay hold the botton closed?
You are technical but not clear may be you should have a better video
