EnglishFollow the steps below to ground test a <strong>CE</strong> <strong>Source</strong> <strong>Four</strong> <strong>jr</strong>/<strong>Zoom</strong>andluminaire.courtesy Audio-Visual of Services1. Plug the luminaire into the PAT outlet and attach the test clipto the PAT point on the luminaire.Phone: 0870 080 2342mail: www.sxsevents.co.ukenquiries@sxsevents.co.uk2. Set the PAT device to test at 10 amperes and press the GO/TEST button.If your PAT device doesn’t allow you to change the amperage, itcan still be used for the test. However, the earth tether, whichconnects the burner assembly to the body of the unit, may gethot enough to cause injury and could become permanentlydiscoloured. This is normal for test currents above approximately20 amperes.The PAT device should read less than 0.5 ohms. Most <strong>Source</strong><strong>Four</strong>s give a reading of less than 0.1 ohms, if in good condition.The Insulation testThe insulation proves that the internal insulation is in goodcondition. You can use standard PAT devices to perform theinsulation test. Follow the steps below to test the luminaire’sinsulation.1. Plug the luminaire into the PAT outlet and attach the test clipto the PAT point on the luminaire.2. Set the PAT device to test at 500 volts D.C., then press theG0/TEST button.A reading below 1M ohms indicates a possible or imminentfailure. Moisture build-up around the lamp holder or in theconnector or foreign matter accumulated around electricalconnections can cause a low reading.Why a <strong>CE</strong> <strong>Source</strong> <strong>Four</strong> <strong>jr</strong>/<strong>Zoom</strong> may give a fail readingThe majority of appliances must fulfill a ground resistancerequirement of 0.1 ohms or less. Some simple, low-cost PATdevices assume the 0.1 requirement and do not offer a methodfor reading the actual resistance or for setting the fail level to 0.5ohms. These devices may provide a fail reading for an acceptableunit if the resistance is slightly above 0.1 ohms. If in doubt, checkwith your PAT device supplier and verify that the PAT device cancorrectly test a luminaire for the 0.5 ohm condition.How often to testYour local regulatory authority has guidelines on the testingfrequency.www.sxsevents.co.uk12 • <strong>CE</strong> <strong>Source</strong> <strong>Four</strong> <strong>jr</strong> & <strong>CE</strong> <strong>Source</strong> <strong>Four</strong> <strong>jr</strong> <strong>Zoom</strong>
