    All connections herein are factory set and should not be adjusted on site. It is strongly advised to only open this compartment after consultation with Elster. Figure 2-1: SPU Compartments For all external connections to the meter the connection holes in the bottom of the rear compartment should be used (see Figure 2-2).

  • Page 10: Installation Instructions

    Installation Instructions holes shall be equipped with certified stopping plugs; non-certified plugs (e.g. used for transport or storage) shall also be replaced by certified plugs. The client is responsible to provide suitable glands and stopping plugs, with regards to e.g. thread type, hazardous area certification, ingress protection. The rear compartment contains the field terminal board (see Figure 2-3).
  • Page 11 Installation Instructions Be Aware! Special attention needs to be taken when the UFM Series 6 must be installed in accordance with MID. Please see the Operation and Maintenance Manual of your particular flow meter, latest valid revision. For FM and CSA Approved UFM Series 6 Meters, please also see the related control drawings and installation remarks in the UFM Series 6 Safety Instructions manual.

    Switches and LED Indication 6 Switches and LED Indication 6.1 Switches on the Field Terminal Board The field terminal board contains four switches, SW1 to SW4 (see Figure 6-1) to control communication lines and power input. Figure 6-1: Switches on the Field Terminal Board 6.1.1 This switch is placed for the line termination of the serial communication lines (see Table 6).

  • Page 21: Sw2 And Sw3

    Switches and LED Indication In practice the line is terminated at the last meter in the RS485 multidrop network with a resistor. The ‘SW1’ switch has two separate line terminations, one for each RS 485 port.  ‘SW1-1’: is the line termination of port 1: (pin number 1-3 of TB3, see Table 6).
