  • Page 10 FEC920: USER GUIDE This instrument is intended for industrial temperature and process control applications within the requirements of the European directives on safety and EMC. Installation may be carried out only by qualified personnel. To prevent hands or metal tools coming into contact with parts that are electrically live the instrument must be installed in an enclosure.
  • Page 11 FEC920: USER GUIDE USB DEVICE PRECAUTIONS Note: The use of U3 USB Flash drives is not recommended. Precautions against electrostatic discharge should be taken when the instrument terminals are being accessed. The USB and Ethernet connections are particularly vulnerable. Ideally, the USB device should be plugged directly into the instrument, as the use of extension leads may compromise the instrument’s ESD compliance.
  • Page 12 FEC920: USER GUIDE 2 CYBERSECURITY WHAT’S IN THIS CHAPTER This chapter outlines some good practice approaches to cybersecurity as they relate to use of the FEC920 instrument, and draws attention to several FEC920 features that could assist in implementing robust cybersecurity.

  • Page 47 FEC920: USER GUIDE Adding parameters to the input and output tables can be achieved only through the proprietary software package ‘iTools’, running on a PC. It cannot be configured through the user interface. The following description assumes that the user is familiar with ‘iTools’. Section 9 of this manual shows how to set up an iTools link to the unit and the iTools on-line help system and its PDF version (HA028838) should be referred-to as necessary.

    The client identifier is a unique id used by DHCP servers that implement option 61. Each FEC920 product will have a unique ID built up from its MAC address. If the DHCP server is configured to use option 61, then it will use this ID instead of the MAC address to assign a dynamic IP address.

  • Page 72: Archiving

    Note: For remote archiving, the host computer must be set up to respond to ‘pings’. This is because the FEC920 pings the host whilst establishing connection, and if it does not receive a response, the archive attempt fails.

  • Page 83: Channel Trend Configuration

    FEC920: USER GUIDE Note: Break High impedance values would be used typically for sensors which have a high nominal impedance when working normally. Input sensor break detection is not supported for secondary inputs. The internal circuit acts as a ‘pull up’ on the secondary input which therefore saturates high in the event of a sensor break.

  • Page 84: Alarm 1 Menu

    FEC920: USER GUIDE SPAN EXAMPLE In an input range of 0 to 600 degrees C, the temperature range between 500 and 600 degrees is of most interest. In such a case, Span Low is set to 500 and Span High to 600 so that the instrument trends only the required part of the temperature range, effectively magnifying the area of interest.

This shows that the alarm is Off, Active, SafeNotAcked or ActiveNotAcked. For ‘Auto’ and ‘Manual’ alarms only, ‘SafeNotAcked’ means that the alarm trigger source has returned to a non-alarm state, but the alarm is still active because it has not been acknowledged.
  • Page 86 FEC920: USER GUIDE Active Read-only. Shows the status of the alarm as ‘Yes’ if it is active, or No, if inactive. The active/inactive state depends on the Latch type (above) and acknowledgment status of the alarm. Always shows ‘No’ if the alarm is inhibited (below).

  • Page 91: Totalizer Configuration

    The totalizer block in the FEC920 is intended to automate this process. It uses the built-in sampling rate of the FEC920 (125mSec) as the sampling period for the totalization process. In addition, it provides two separate parameters which can be used to adjust the results of the totalization process so that the output from the block is scaled in the correct units.
