Fastening Strategy Strategy used to control or monitor a fastening process
Final Angle Final angle desired in a fastening process
Histogram Printout generated from statistical data output
If NOK go to stage Gives the control system direction if the stage is NOK
Internal Transducer Transducer physically located inside the tool
LCD Screen Screen on the unit that provides directions to programming the unit
LED Screen Screen on the unit that provides the readout data from a run cycle
Linking Linking allows the user to automatically change from application to
application (max. 99) for a predefined number of steps (rundowns).
The automatic changes are available for 32 tightening groups. The
corresponding tightening groups can be selected with the Run
Screen or by external selection.
Load Refers to the amount of torque applied to a device or tool
Main Menu First menu that appears on LCD screen
Master Transducer Transducer used as a benchmark to calibrate another transducer
Max. Fastening Time (mS) Maximum time for the tool to run during the stage
Maximum Tool Speed Maximum admissible speed of tool
Mean (Xbar) Average of all readings taken in a sample
NOK Active if Torque/Angle/Yield Point are outside the programmed limits
or some other fault has occurred
NOK After Reverse If yes, the controller will report an NOK if the tool is run in reverse
Number of Repeats NOK (link-
ing)
Selects the number of times a fastener can be retightened after an
NOK before going to the linking position.
OK Active if Torque/Angle/Yield Point are within the programmed limits
Peak Torque Maximum torque achieved in a run cycle
Port Socket used for connecting a cable or peripheral equipment
Position (Linking) A number between 1 and 96 which describes rundown position dur-
ing linking
Power Supply Unit used to supply power to an electrical device
Pulses per Degree Number of encoder pulses generated by the tool when rotating the
head exactly 1 degree or 1/360 of a revolution
Range ® Statistical measurement of the difference between the lowest and
highest reading taken in a sample
Redundant Transducer Secondary transducer used to read torque
Reject Release Stopping of further operation of the system after a predetermined
number of rejected cycles has occurred
Rejected Data Data generated by unacceptable rundowns
Rejected Rundown Rundown that has not met the criteria of a fastening strategy
Remote Parameter Select Remote device for application selection
Reset After NOK (linking) Determines whether the controller will reset to linking position 1 after
an NOK
Resolver (angle encoder) Sensor for measuring rotation angle
Run Number Number of accepted and rejected rundowns
Rundown Printout Gives the control system direction for when to print
Second Transducer Frequently referred to as the Redundant Transducer
