Info

Process Unit 73 LF Installation and Start-Up Installation of the Process Unit 73 LF must be carried out only by specially trained personnel in accordance with this instruction manual and per applicable local and national codes. Make sure that the technical specifications and input ratings are observed. For information on installation, refer to chapter 10. Start-up of the Process Unit 73 LF must be carried out only by specially trained personnel in accordance with this instruction manual and per applicable local and national codes. Before first start-up, a complete parameter setting procedure must be performed. At ambient temperatures below 0 C, LC display readability might be restricted. This does not affect instrument function. Real-time clock, logbook, cal record and sensor statistics are battery backed for approx. 1 year. After longer power outages these data can be lost. In that case the Process Unit displays ”Warn Time/ Date” and the date is reset to 01-01-1990. Time and date must be updated. II Information
Information on Electromagnetic Compatibility Compliance with Interference Immunity Requirements All inputs and outputs of the Process Unit 73 LF are electrically isolated to each other. The isolation voltages are limited to approx. 50 V by gas-filled surge arresters (to meet EMC requirements to NAMUR). Option 351 (Remote Interface) For connecting the RS 485 interface, twisted and/or shielded cable must be used. To meet the radio interference limits at the RS 485 interface, terminal 15 (shield) must be grounded. Do not use the protective conductor for grounding! The Process Unit 73 LF meets the following generic standards: Electromagnetic Emission EN 50081-1 Domestic, Commercial and Light Industry Immunity to Interference EN 50082-2 Industry and can therefore be used on residential, commercial and light industrial premises and in industry.
