7.1.5 Performance Characteristics – EMC
Configuration of equipment:
Fitted with an unscreened power cable. Also included were two separate mA
output cables, each individually screened. Each signal pair was fitted with
ferrite bead (Servomex part No. 2824-0017). The screens and drain wires were
terminated at the glands.
Results:
Met the requirements of EN 61326, Table 4, Class B (Equipment for use in
domestic establishments) in respect of conducted and radiated emissions.
Met the requirements of EN 61326, Table A1 (Equipment for use in industrial
establishments) in respect of electrostatic discharges, fast transients/bursts,
surges, conducted RF disturbances, voltage dips and interrupts.
An additional error of 3% FS over the intrinsic error given in Table 7.2 may be
observed at some frequencies under the influence of radiated RF fields
specified for industrial environments.
Connection of additional or other signal/control cables and pressure
compensation could lead to a deterioration in performance at some RF
frequencies.
