Extract from customer s literature: FLOCKMAN has been designed for the individual broiler grower to give similar benefits to the old more sophisticated product FLOCKMAN that is aimed primarily at the larger integrated broiler company. Although it controls lighting programs (with dawn/dusk dimming), whole cereal inclusion and automatic meal-time feeding for each day, it needs no computers nor automatic feed or bird weighers. Once started at the beginning if the crop, it needs no further input from the grower until after the house is empty, when it is stopped. Page 5 of 26

The display (LCD) cycles indicating Target Cereal Feed (15.0%) followed by actual feed (15.0 to 15.3%) then Light off Pans On, this repeated every 10 seconds. 2.4 EUT Test Configuration Mains EUT Mains HEMCS Breakout box Proximity Sensor Lamp 2.5 EUT Support Balluf Proximity Sensor, s/n EMC002 HEMCS light and breakout box, s/n EMC003 Page 6 of 26

9 3.0 EMISSION RESULTS 3.1 Radiated Disturbance Data A profile scan was taken at a distance of three metres on eight azimuths of the EUT in both the vertical and horizontal polarities of the antenna in a semi-anechoic chamber. Using the data obtained from the chamber profile-scan as an engineering guide, the EUT was then transferred onto the turntable in the Open Area Test Site. The antenna was positioned at a distance of ten metres from the periphery of the EUT. Radiated emissions were then systematically maximised by revolving the EUT and adjusting the antenna in polarity and height. The highest emissions are presented here. Emission frequency (MHz) Antenna polarity Measured quasi-peak value (dbµv/m) Class A specified quasi-peak limit (dbµv/m) Status Vertical Pass Vertical Pass Vertical Pass Vertical Pass Vertical Pass Vertical Pass Vertical Pass Vertical Pass Horizontal Pass Vertical Pass Uncertainty of measurement: +/-4.2dBµV for a 95% confidence level. The measurements reported are the highest emissions relative to the CISPR 22 Class A limits and take into account the antenna and cable loss factors. Measurements made according to the CISPR 22 test standard and Hursley EMC Services test procedure RAD-01. TEST ENGINEER: Stephen Connolly Page 8 of 26

11 3.2 Conducted Disturbance Data A filtered 230V/50Hz supply was fed to the EUT via a 50Ω/50µH Artificial Mains Network (AMN). The AMN was bonded to a conductive ground plane. Line and neutral phases and each power supply were measured separately. A spectrum analyser was set to scan between 0.15MHz and 30MHz to record the peak emission profiles. The worst-case peaks were then measured using an average and/or quasi-peak receiver and compared to the CISPR 22 Class A limits. The worst-case results from both power supplies are shown here.

13 3.3 Mains Harmonics Uncertainty of measurement: +/-5.8% for a 95% confidence level. Measurements made according to the EN standard and Hursley EMC Services procedure HAR-01. TEST ENGINEER: Andy Jones Page 12 of 26

14 3.4 Mains Voltage Flicker Uncertainty of measurement: +/-3.8% for a 95% confidence level. Measurements made according to the EN standard and Hursley EMC Services procedure FLK-01. For voltage changes caused by manual switching, the equipment is deemed to comply without further testing if the maximum RMS input current including inrush current is evaluated over each 10mS half-period between zero-crossings does not exceed 20 amps, and the supply current after inrush is within a variation band of 1.5 amps. Inrush current measurements were made in real time and the product state was altered and the load current unmonitored and the inrush was less than 20 amps and the variation was less than 1.4 amps therefore it complies without testing.

15 4.0 IMMUNITY RESULTS 4.1 Performance Criteria General performance criteria for immunity testing are defined below:- Criterion A Criterion B Criterion C Criterion D During testing normal performance within the specification limits. During testing, temporary degradation, or loss of function or performance which is self-recovering. During testing, temporary degradation, or loss of function or performance that requires operator intervention or system reset occurs. Degradation or loss of function, which is not recoverable due to damage to equipment, components, software, or to loss of data. The test standard (EN 61326:1997 / A1/A2/A3) requires the manufacturer to produce a functional description and a definition of performance criteria applicable to these EMC tests. The customer has defined Unacceptable performance criteria as a deviation of more than +/-1% for the analogue resistor values and the reference value. Other failure conditions are determined by interpretation using the experience of the laboratory EMC engineers. Monitoring of EUT performance whilst under test Radiated immunity: Remote monitoring of the product in the anechoic chamber using a video camera focused on the EUT display and a fibre-optic linked video monitor situated in the control room. All other tests: Visual monitoring of the EUT display and light one zero volt contact to verify correct function and status. Page 14 of 26
