what is safety relay ?
Thanks for sharing the video. It gave me insight on how to handle an electrical breakdown involving the safety monitoring relay circuitry of a machine at my place of work.
Very simple and straight to understand.
Best to add mirrored NC contact from the MCR to the reset circuit so you can check if the MCR is welded shut.
simple and straight forward, thank you
Very easy to understand some job 🎉Thanks
Thanks for the informative video and please create the next video on CAT-3 safety relay.
GREAT WORK. GO LITTLE SLOW. ALSO MENTION USE OF RESET. WHY RESET IS REQUIRED. IF BY SOME REASON SOMEONE OPENS ONE DOOR OF A MACHINE, OR HIT E STOP, THEN THE SUPERVISOR MUST KNOW THE REASON TO OPEN THE DOOR OR HIT E STOP. IF THE RESET BUTTON IS CONNECTED WITH A KEY TYPE PUSH BUTTON, AND IF ONLY SUPERVISOR HAS A KEY FOR RESET BUTTON, THEN IN THIS CASE THE MACHINE OPERATOR CAN NOT START THE MACHINE UNLESS, SUPERVISOR COMES TO MACHINE AND INSERT HIS KEY AND RESET. AND THEN DOCUMENT THE REASON OF HITTING E STOP OR OPENING THE DOOR. HITTING E STOP IS ACTUALLY SERIOUS MATTER. E STOP IS NOT LIKE AN ORDINARY STOP BUTTON. THIS IS A SAFETY. SOMEONE CAN LOSE LIFE. PLEASE EXPLAIN SUCH THINGS ALSO. ONE MORE THING, THERE IS NO USE OF OTHER CHANNEL FOR OUTPUT. GENERALLY TWO CHANNEL WITH TWO MCR IN SERIES ARE USED, REDUDANTLY FOR MORE SAFETY. IF ONE MCR CANT OPEN THEN THE OTHER WILL PROVIDE SAFETY. REST, THE VIDEO IS EXCELLENT.
Great explanation
There should be 2 relays both with n/c contacts in series with reset button. This is called reducency so if one relays contacts are welded close the safety relay will not reset.
Very helpful thanks bro
Very knowledgeable video
Very Nice. I understand.
Thank you very much & if it is connected to VFD, as well how to find fault. Appreciated
S1 S2 on the VFD
Good video. You should have explained the purpose of the MCR also as this is an introduction video
Super easy to understand, great explanation!
Useful thanks
Thank you very much..you helped me
Thank you
Well Done ,
Great video tutorial 👍
,How many stop push botton can install at safety relay?
It depends how many channel relay we are using . Most of the relays have 4 ot 2 channels .
Brilliant video!
Çok teşekkür ederim

Bienvenido
Really I needed this so much Can you please make some more videos on Safety relay?

@@EASYPLCTRAINING sir I want to know how switching takes place- Like normal relay or PNP switching?
Normal relay
@@EASYPLCTRAINING Sir Can you give you mail ID- I want to share picture of Safety relay which we use!!!
@@EASYPLCTRAINING Thanks
Please do the same for pheonix contact safety relay material.
Mejor seria explicarlo con un detector de seguridad, asi podriamos ver que tenga que estar implementado todos los sistemas de seguridad. Una seta de seguridad puede estar conectada sin tener que pasar por el relay de seguridad.
👍🏻👍🏻👍🏻👍🏻
How to wire Safety relay omron G9SE 221 T30 to E-Stop with a reset switch and VFD + electrics witch on / off + reset switch + emergency stop + contactor
Sir, why are we using contactor in this circuit
Sir
How to Bypass Relay in Circuit....when Relay not working
Channel 1 light is not on what is the problem....!? Plz feedback me
Why is a 2NC e-stop needed
It's needed here in this application for greater redundancy - i.e. if there is a fault in one of the contacts the safety relay will go into fault as it's looking at both NC contacts. You could use a NC emergency stop button with a single channel safety relay, but having a 2NC emergency stop button with a dual-channel safety relay is safer, depends on what your application is.
How do you bypass it
