GE ASTAT XL User Manual

ASTAT XL User Manual Fout! Stijl niet gedefinieerd.68 DET-812Display Possible cause/Suggested solutionFiring Fail Px Where 'X' is phase 1, 2 or 3.The SCR did not fire as expected. The SCR may be faulty or there may be aninternal wiring fault.This trip is not adjustable.Related parameters: NoneFLC too high The ASTAT XL can support higher motor full load current values whenconnected to the motor using inside delta configuration rather than in-lineconnection. If the soft starter is connected in-line but the programmedsetting for parameter 1A Motor Full Load Current is above the in-line maximum,the soft starter will trip at start (see Minimum and Maximum Current Settings onpage 11).If the soft starter is connected to the motor using inside delta configuration, thesoft starter may not be correctly detecting the connection. Contact yourlocal supplier for advice.Related parameters: 1A, 1CFrequency The mains frequency has gone beyond the specified range.Check for other equipment in the area that could be affecting the mainssupply, particularly variable speed drives and switch mode power supplies(SMPS).If the ASTAT XL is connected to a generator set supply, the generator may betoo small or could have a speed regulation problem.Related parameters: 4G, 4H, 5G, 16FHeatsinkovertemperature Check if cooling fans are operating. If mounted in an enclosure, check ifventilation is adequate.Fans operate during Start, Run and for 10 minutes after the starter exits theStop state.NOTEModels QLxxB0023D to QLxxB0053D and QLxxB0170D do not have acooling fan. Models with fans will operate the cooling fans from aStart until 10 minutes after a Stop.Related parameters: 16JHigh Level This is a name selected for a programmable input. See Input A trip.High Pressure This is a name selected for a programmable input. See Input A trip.Input A trip The soft starter's programmable input is set to a trip function and hasactivated. Resolve the trigger condition.Related parameters: 4E, 5E, 5F, 6D, 6E, 16EInstantaneousovercurrent There has been a sharp rise in motor current, probably caused by a lockedrotor condition (shearpin) while running. This may indicate a jammed load.Related parameters: 4D, 5D, 16DInternal fault X The ASTAT XL has tripped on an internal fault. Contact your local supplier withthe fault code (X).Related parameters: NoneL1 phase lossL2 phase lossL3 phase lossDuring pre-start checks the starter has detected a phase loss as indicated.In run state, the starter has detected that the current on the affected phasehas dropped below 2% of the programmed motor FLC for more than 1 second,indicating that either the incoming phase or connection to the motor has beenlost.Check the supply and the input and output connections at the starter and atthe motor end.Phase loss can also be caused by a failed SCR, particularly an SCR that hasfailed open circuit. A failed SCR can only be definitely diagnosed by replacingthe SCR and checking the starter's performance.Related parameters: None
