12A. IGNITOR SWITCHB. IGNITOR UNITBLN0123456220/240AWiring DiagramFault FindingPreliminary Electrical SystemsCheckA. EARTH CONTINUITY CHECK - Appliance must beelectrically disconnected - meter set on Ω (Ohms) x1 scale and adjust zero if necessary.a) Test leads from any appliance earth point to earthpin on plug. Resistance should be less than 0.1ý (Ohm), check all earth wires for continuity andall contacts are clean and tight.B. INSULATION CHECK - Appliance electricallydisconnected, all switches ON.a) meter set on Ω (Ohms) x 1 scale.Test leads from L to N in appliance terminal block.If meter reads «0» then there is a short circuit.b) meter set on Ω (Ohm) x 100 scale.Repeat test with leads from L to E. If meter readsless than ∞ (infinity) there is a fault.NOTE - Should it be found that the fuse has failedbut no fault is indicated - a detailed continuity check(i.e. by disconnecting and checking eachcomponent) is required to trace the faulty component.It is possible that a fault could occur as a result oflocal burning/arcing but no fault could be found undertest. However a detailed visual inspection shouldreveal evidence of burning around the fault.STARTIsolate applianceand carry out:A: Earth Continuitycheck.Has inlet fuse blown?Carry out:C: Polarity check.Electricity supplyshould now besatisfactory.Carry out:D: Resistance toEarth check.Inlet wiringfaulty.Rectify anyfault.Isolate appliance andcarry out:B: Insulation check.Rectify any faultincluding replacingfuses as necessary.SOCKET(face view)PLUG (with coverremoved)Earth WireGreen/YellowNeutral WireBlueBrownBlue GreenYellowGreenYellowBrownBlue( )FUSE( )EN LNO YESNO YES
