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
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
As per my best knowledge , I think there is NO option in AFPC Menu to change UNDC(under current ) setting . Secondly this is mandatory protection which update you that there is some issue in current input.
👏👏
Thanks for appreciation
Etasmart8t k common me ac volt denge ya dc volt
Brother 8R - means you have to use normal cap duty Contactor
And 8T means it’s designed for thyristor
Use only when you have thuristor
Nice ❤
Thankyou
Sir
Default setting is : 0.015 of In hai.
Aap default setting rakh sakte h koi problem ni h
SIR,WHEN WE KEPT THE AUTO MODE IMMEDIATELY 2NO CAPACITOR RUNNING.NO LOAD PURPOSE.BUT I HAVE NO NEEC.HOW CAN REMOVE THIS ONE

Really me pf velu settings karne K bad pf velu display per km btarahi he.is lie koi solutions btaen plz site per phasa hoa hon
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
RMC current keshe set kare
Set Nahi kar sakte it’s real time measurement

Mera APFC panel EK MINUT KE ANDAR UNDC aa rha hai phir undc off ho rha hai yani bar bar on ho rha hai capacitor . 5 amp current me

OCOM aur UNDC alarm ki setting kaise karna hai. Kaunse menu main Jana hai
As per my best knowledge , I think there is NO option in AFPC Menu to change UNDC(under current ) setting .
Secondly this is mandatory protection which update you that there is some issue in current input.
mujhe UNDC ka threshold change karna hai. kya aapke pass apfcr ki koi manual hai? @@eeebackbenchers
Undc aa raha etasmart 6r me how to solve this problem
Bhai Undc ( under current) Matlab ct se sufficient current nahi aa raha . Check ct output at Apfc end
How to solve UNDV (alarm) problem
Simply means undervoltage : check voltage level and ensure the rated voltage at defined terminals
2500/5 ki ct h undc fault h to 0.015---0.5 me se kya seting hogi
Apft
37.5amp...ok
Hello sir
how to slove UNDC
Sir
Undc means under current , means there is no sufficient current from ct
Check ct output secondary current at Apfc ct terminals and car polarity
RMS line to line voltage worg voltage show disply why problem
Verify voltage level at APFC terminals & ensure connection should be done as per manufacturer recommendation.
RMS current nahi aye toh
Matlab Jis CT se Apfc main sensing aa raha h ausmain load nahi hai
Ithd alarm aa raha hai
Current harmonics is higher than 25%
You should you detuned reactor or do harmonics study on your plan for better result
