  • Page 20: Start-Up

    In general, we would recommend that you have the start-up carried out by the service of the company Berthold. IMPORTANT When operating the EVU, you must adhere to the manual "Mould Level Shieldings". Berthold recommends building a separate power connection for each meas- urement channel (Fig. 3). 47344BA2 Rev.05, 05/2019...
  • Page 21 LB 452 4 Start-Up The advantages of a separate power connection for each measurement channel are: Each measurement channel is supplied by its own Functional reliability in voltage source. the event of surges or short circuits If there is a fault in the power supply for one Redundancy strand, the other measurements can still be carried out without interference.
