  • Page 14: Mounting Instructions

    Welded socket LFV 330 has a defined thread starting point. This means that every LFV 330 is in the same fork position after being screwed in. Remove therefore the supplied seal from the thread of LFV 330. This seal is not required when using a welded socket with O-ring in front.
  • Page 15 For this reason, do not use an overly long extension tube for LFV 330, but check if you can mount a level switch on the side of the vessel in horizontal posi- tion.

    The operator of the system is responsible for taking suitable meas- tion occurs ures to rectify faults. Causes of malfunction The device offers maximum reliability. Nevertheless, faults can occur during operation. These may be caused by the following, e.g.: • Sensor • Process • Voltage supply • Signal processing Fault rectification The first measure to take is to check the output signal. In many cases, the causes can be determined this way and the faults quickly rectified. LFV 330 • NAMUR...
