Good day Peers I would like assistance, with a Siemens SIVOLT A drive 6SG24 drive. This drive is used for heating applications and has been in use for over 10 years. The drive is controlled via a 4-20mA input to control the Thyristor firing and hence heat generated by the heater on the plant. Recently (2 weeks ago) after a small plant outage the heater started firing at maximum and was uncontrollable, after detailed fault finding the fault was traced to the drive and it was noted the drive is not responsive for any signal input and consistently fires on maximum. Please see attached drive block diagram with the respective control points shown. Any assistance would be appreciated. Kind regards AttachmentSIVOLT A drive.pdf (681 Downloads) |
