Thanks accepted 🙏😂😂😂

thanks for comment brother ! see multiple reason behind this. First thing OSF stands for " Mains overvoltage fault " it will be happended due to :- • Line voltage is too high: • Disturbed line supply and power quality issues( check harmonics level).

​@@eeebackbenchers but then it should show before starting also right? It is happening only after stopping the pump. Also other 4 pumps doesn't have this issue.

kzbin.info/www/bejne/bWTLiYWVab6okNUsi=LecuEIk_zlnybYPY - in this video you will found how reset the fault

Thanks brother

Do one thing refer manual of description box and you will get the example of wiring ( simple connect common terminal with desired terminal with NO PUSH BUTTON) you will also get reference video on channel

Thanks brother for you comment , it means lots to me . Thanks again

At time 05:22 please refer page and you will get the terminal details with speed up and down parameter , still any doubt comment me back with terminal no where you want to speed up and down

Manual already in description box please find

Refer description box

sorry for late replay. An over current trip - (OCT) over voltage trip - (OVT)

Bhai ,message is not clear to me but as I understand you taking about when you put auto mode selection from panel selector switch when 02 contactor ON immediately. If this case , then wiring problem is confirm . In this case you also verify that when contactor ON and Apfc respective LED should not ON

Simply means selected capacitor bank are not sufficient to compensate system inductive power. Need to add more capacitor in this case

@eeebackbenchers but another controller showed pf has been reched!

yes. DETAILS OF PARAMETERS : V, A, F, PF, kW, kVA, Run hours, kWh (EB and DG), Old energy, Site selectable kWh / kVAh

already revert.

bhai to perform the test , no password is required. what is purpose to get maintenance password.

Memory card showing error

That's why password is required

Possible to share urs contact no

Can i get urs contact no

Thanks for comment brother, * 1NO contact assigned to start button ( you can use as per you control circuit requirement like as a start command). * Reset is used to reset the fault. 1NO- Alarm 1NC- TRIP Hope its clear now.

Kya error aa raha hai

Hello sir , I never tried this so unable to comment on this .

Thank you

You please share your contact number

Thanks for comment but I never face such problem I think you should contact to Epcos only

Thankyou bhai

Bhai Undc ( under current) Matlab ct se sufficient current nahi aa raha . Check ct output at Apfc end

Pf value kam Kaha Bata raha hai Matlab setting main enter karne ke baad ya view setting main ya , actual of kam dikka raha hai

Share your number if still there is problem I will call you

Thanks for comment , please note the digital input DI1 is assigned to : * ( forward) in 2- wire control * (Drive running) in 3- wire control Or do factory setting by default it s forward

Thankyou dost

It seems like some ct connections are loose , also check ct current output it should be higher then min. Requirement . You can also also refit the ct connector of apfc

Thanks

Sir, my L&T dual source energy meter WL4040 in not uploading daily energy readings.. please guide me.

Check faulty history and check tripping value , if set value is low the increase it If cbct used then check power cable pass though it properly And last if ct secondly used then check ct secondary polarity

Thank you to also for appreciating the efforts .

Hello Please note you don’t need to change any parameter in expert mode 1 and expert mode-2 You can keep 12 and 13 by default

Over compensation ( ocom) : means your power factor already in leading state hence it will not switch on any cap bank

@@eeebackbenchers फिर तो अलार्म नही आना चाहिए ना

Thanks for comment check following setting Main menu /complete setting/command and REf./stop Key enable /All. Try this and second reason may be your fault is permanent hence it is not resetting from DI , in such case it will reset only via Drive power ON-Off. Please try if it work , please update.

Already revert

Do one thing first Go and check io status and verify that all the IO are healthy or not as per command given. Second thing Check drive should be ready to start mode mean to say check there is no fault or any warning in this drive hmi will show red led. I think after check these points drive should be start if still not working please contact to Schneider’s customer care

Current harmonics is higher than 25% You should you detuned reactor or do harmonics study on your plan for better result

Thanks for comment

Good question, as per my knowledge mtx3.0 connector not comes along with universal kit . Secondly there is separate testing kit for MTX AND ITRP Mccb release And last if you don’t have dedicated testing kit then you need communication module and display module.

Thx a lot for reply can you please share name model of testkit suitable for LSIG setting MTX 3.0 of MCCB. Thx n Regards Rajesh

@@rajeshparmar6944 Sir this kit is not available in open market ( mean to say not for sale) , only available for L&T Service team , if you want to test our MTX3.O you can contact with L&T ( CIC customer care)

I will check all the connector of universal kit if any possibility to check MTX 3.0 then I will check n update u If you get any chance to test then please check and inform

Thanks for comment brother , right now I don’t have such setup If you have any doubt on any topic feel free to comment I will try to resolve the same.

Welcome

Basically NLP(No line power) hence it is a warning not fault. Secondly you can check following points 1. Check input supply 2. In drive parameter check main voltage ( in term of dc it should be around 600 V - actual line 400x1.5 ) calculate accordingly. And hard reset the drive If still problem presist call drive expert

To do change frequency we have to programming accordingly and we can change frequency in remote via DI and AI

Basically all the switchgear companies sell product frame wise Frame stands for standard dimensions If I say FRAME -1 , means all the rating ( 630 /800) which comes under FRAME 1 have standard size/dimension Similar for upper 3-4 rating frame 2 And then for upper rating frame 3 it also have 2 or 03 rating Rating range change as per manufacturer but concept remains same. Hope it’s clear now

Thankyou so much sir for appreciating.

Noted , actually programming pattern is almost same in both the drives . If drive arranged some where I will make video.
