2.2 EUT Description
FLOCKMAN is an Automated control system for poultry production.
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.

2.3 EUT Test Exerciser
The volt free contact for Auger Cereal turns on once every 60 seconds for 10 seconds, a mains
powered light bulb was connected to this input to indicate the contact was opening and closing. 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.

3.0 EMISSION RESULTS
3.1 Radiated Disturbance
3.1.1 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.

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.

3.2 Conducted Disturbance
3.2.1 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.

3.4 Mains Voltage Flicker
Uncertainty of measurement: +/-3.8% for a 95% confidence level.
Measurements made according to the EN 61000-3-3 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.

4.0 IMMUNITY RESULTS
4.1 Performance Criteria
General performance criteria for immunity testing are defined below:Criterion A
During testing normal performance within the specification limits.
Criterion B
During testing, temporary degradation, or loss of function or performance
which is self-recovering.
Criterion C
During testing, temporary degradation, or loss of function or performance
that requires operator intervention or system reset occurs.
Criterion D
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.
