I was looking for a vacuum replacement part and Amazon accidentally came up with safety relays and now I'm here. I'm not even an electrician, I'm an artist. Thanks for satisfying my curiosity
I can't finish my expression over the result of your videos i give and spend my time following and watching your videos. I wish to have a direct contact and connection with you guys for more. kudos
I often encountered these safety relay often bypass because they say that it is hard to troubleshoot due to to many wirings, sensitivity and interlocks. That is why you need to know the importance and the purpose of thess safety relays and the consequences if you did bypassed it
Thanks for the great infos on this vid. Just wondering what happens when you try to short a relay output from A1 to S21 and suddenly sparks? Is the safety switch still functional or is it damaged inside?? Does it need replacing?? Thanks again.
@@ElectroAcademyEA I guess your assumptions about my question are not really true because the safety relay is still working correctly. Thanks for your time.
S11-S12 and S21-S22 are input switches and must be in the closed position for internal contactors K1 and K2 to be closed. Contactors K1 and K2 (placed inside the safety relay) must be in the closed position for control power to be available at terminal 14. Although 24 volts for reset power have been connected from S12 of channel 1, the system cannot be restarted without channel 2 enabled. So, the motor run contactor control power will not be out from terminal 14, without closing both the S11-S12 and S21-S22 switches.
@@ElectroAcademyEA Thank you very much for clarifying this. Please do more safety videos as there as so many different types of safety controllers in industry
When Magnetic Contactor main points are stuck with welded condition, safety relay operation alone cannot stop the motor. Then Master Relay can stop main power to the motor by shutting off its power.

Does it need replacing??
Thanks again.
Surely it will get damaged since components like capacitors, transistors, diodes, are at high risk of being destroyed.
Thank you.

S12 supplies 24 V to S34 to reset. Is s12 just looking at channel 1 ? Please advise.
S11-S12 and S21-S22 are input switches and must be in the closed position for internal contactors K1 and K2 to be closed.
Contactors K1 and K2 (placed inside the safety relay) must be in the closed position for control power to be available at terminal 14.

@@ElectroAcademyEA why we need to ground s21
Amazing video 👍
Thank you
Why do we need a Master Relay before the Magnetic contactor?
When Magnetic Contactor main points are stuck with welded condition, safety relay operation alone cannot stop the motor.
Then Master Relay can stop main power to the motor by shutting off its power.
Greatttttt
Thank you
Emergency stop doesnt stop the circuit ?
If the motor running contactor has a contact welding condition, emergency stop cannot stop that faulty contactor from operating.
