9.8.4 TIME REJECT conditions
THe TIMe Reject LED will light for the following reasons:
1. A "RED" TIme Reject LED on the AXIS Unit indicates a Final step Time Reject.
2. An "ORANGE" TIme Reject LED on the AXIS Unit indicates a 1st step TIme Reject. May
cause a LOW TOrque Reject.
CAUSES:
1. THE amount of time specified on the Parameter Set screen is insufficient.
2. THe socket did not engage the fastener properly.
3. THe fastener did not engage the workpiece properly.
4. The socket is split or damaged.
9.8.5 TORQUE RATE REJECT conditions
TorquE RAte (RAte) is defined as the change in torque divided by the change in degrees of
rotation (ANgle) during a specific interval.
1ST RATE
1.
A "RED" 1ST RATE Reject LED on the AXIS UNit indicates that the Torque Rate, as
measured from Threshold1 (THR1) to 1st TORque, is above the high limit specified
on the PARameter Set screen. May cause a LOW TOrque Reject.
2.
AN "ORAnge" 1ST RATE Reject LED on the AXIS UNit indicates that the Torque
Rate, as measured from THR1 to 1st TOrque, is below the low limit specified on the
Parameter Set screen. MAy cause a LOW Torque Reject.
2ND RATE
1.
A "RED" 2ND RATE Reject LED on the AXIS UNIT indicates that the Torque Rate, as
measured from 1st TORque to CROSSOVER RAte 2 Torque, is above the high limit
specified on the Parameter Set screen. May cause a LOW TORQUE REJECT.
2.
AN "ORANGE" 2ND RATE Reject LED on the AXIS Unit indicates that the torque
RATE, as measured from 1st TORque to CROSSOVER RAte 2 Torque, is below the
low limit specified on the PArameter Set screen. MAY cause a LOW TORQUE
REJECT.
3RD RATE
1.
A "RED" 3RD RATE Reject LED on the AXIS UNIt indicates that the rate, as
measured from CROSSOVER RAte 2 Torque to fastening end, is above the high limit
specified on the PARAmeter Set screen. May cause a LOW TORQUE REJECT.
2.
AN "ORANGE" 3RD RATE Reject LED on the AXIS UNIt indicates that the rate, as
measured from CROSSOVER RAte 2 Torque to fastening end, is below the low limit
specified on the PARAmeter Set screen. May cause a LOW TORQUE REJECT.
CAUSES of HIGH RATE Rejects:
Reduced lubrication, thread obstacle, reduced joint compression.
CAUSES of LOW RATe Rejects:
EXcessive lubrication, thread obstacle, excessive joint compression.
