Hi guys, thanks to all for helping me.
2000kg/hours potato frying(chips line) burner 30 kw fan motor getting trip when it is working on boil out mode.Boil out mode fresh air damper is fully opened and it is tripping when it is at 50 hz.But our observation frying mode motor is not getting trip due to fresh air damper is fully closed.so at the moment we reduce maximum forward frequency to 47 hz and motor is not tripping in both mode but we are facing a problem that combustion chamber temperature goes to high from 630 deg cen to 830 deg cen and hot steam is not
sucking completely because we reduce frequency.
weekly one time for 8 to 10 hours we are using boil out and other time it is working in frying mode.
so now we planning to run the motor in two speed.one for boil out and other for frying mode.
4-20ma analog output coming from plc.i dont like to distrub the original circuits but i would like to add one preset for boil out mode running as per preset value.
we are using 2 wire control.we dont installed any input/output card.only one DI2 is spare.only one preset is requird.
kindly see my past posting circuits diagram and inverter control terminal.
kind regards and appreciated for you valuable time.
