Product DescriptionSelf Test ModeTipV: 70.0SetV: 100 ARCTipV shows internal reference voltage in testmode. Up is on and flashing because SetV isgreater than TipV.TipV: 70.0SetV: 68 ARCDOWN is on and flashing because SetV isLessthan TipV.NOTE: Your TipV reading may vary from the above screen.Whatever it is the first time you run the self test write it downHERE: It should always be within 1/2V of that valueTIPSSelt Test is a quickway to confirm thatthe LCTHC isfunctioning properlyand that the correctsignals are reachingMACH. It helpssimplify the processof tracking down thesource of a problem.Any analysis of aproblem with plasmacutting should startwith running the selftest and using it todefine the propernext stepWhat it DoesSELF TEST MODEWhat it MeansSwitches (Tip Volts) voltage input from THCSENSOR jack to internal precision reference.Value is displayed in TIPVSwitches ARC OK input to internal signal(ON). ARC OK is ON on LCD.Switches SetV to “Test” value (separate valuefrom running SetV value)Compares TipV (reference value) to test SetVvalue. higher the DOWN arrow indicator turnson and the DOWN ouput to MACH flashes totest the input in MACH.Internal reference supplies a known DCvoltage to the TIP VOLTS circuit. It confirmsthat all of the internal electronics for readingTipV is functionalIndicates the internal circuit is reading theARC OK input correctly. Also shows if theARC OK link to MACH is working /configuredYou will not change the normal value of yourSetV value. When you return to normaloperation the SetV value will be the same asbefore.Tests internal electronics for proper operationwith changing values. Tests the UP andDOWN actions of the LCTHC and allowsconfirmation it's getting to MACH.Page 11
