Prashant what value of frequency you put to solve this problem.
Mr Perashant
This is part of your comment
((Moreover, we checked some electronics part and measured voltage at some test points....found EM monitor voltage = 0 and EM fault voltage =4.70 which indicates some fault..))
We have problem in EMV producer
Did you change this high voltage?
For our case its voltage is exact yours.
It's output is zero when we start run.
I know pin numbers
Pin 6-7 are GND
PIN5 is +24 volt
PIN4 - is EMV monitor
PIN3 -is EMV control( main board give a voltage between 0-5 V to this pin)
Pin2- is EMV fault
Pin1 - unknown for me.
