Torque
This strategy guides the operator in reaching the desired target torque, without any angle reading.
Parameter | Description |
|---|---|
Required tag number | A specific number must be written in the TAG of the end fitting tool. |
Name | Name of the tightening program. |
Rundown complete torque | Torque value from which the tightening operation starts. |
Torque min | Lower torque limit. |
Torque max | Higher torque limit. |
Change bolt limit | If the torque applied reaches this limit, the message Change screw is shown on the wrench display. |
Target torque | The torque target. |
Torque units | Select the unit of measurement. |
Torque correction coefficient | When extensions are used, the wrench measurement might be compensated to show a more accurate torque value. To calculate the correction coefficient, please refer to How to calculate the Torque Correction Coefficient. When extensions are not used, Torque correction coefficient = 1. |
Batch size | Number of tightenings the batch will perform. |
Max consecutive NOK | Number of accepted NOK to have an OK result. |
End cycle time | Starts when the torque goes below the Rundown complete torque after reaching the 3rd percentage. |
Ratchet time | Starts when the torque goes below the Rundown complete torque without reaching the 3rd percentage value. This allows the operator to release the torque for a while and recharge during the tightening operation. |
A | Torque max | B | Target torque |
C | Torque min | D | Rundown complete torque |
The green area indicates the OK result area.
The torque result is the maximum torque measured during the tightening.
During the tightening operation, LEDs, buzzer and vibration are activated as follows:
LEDs:
First radial gradient LEDs (two directions): torque over 1st percentage (30% of the Target torque).
Second radial gradient LEDs (two directions): torque over the 2nd percentage (60% of the Target torque).
Third radial gradient LEDs (two directions): torque over the 3rd percentage (95% of the Target torque).
Torque vs. Angle A
Torque max
B
3rd percentage
C
2nd percentage
D
1st percentage
Buzzer
The beep starts when the torque goes over the Rundown complete torque value; the signal increases when the 1st percentage, the 2nd percentage, the 3rd percentage, and the Torque max are reached.
Vibration:
Starts together with the third radial gradient LEDs.
At the end of the tightening operation, LEDs, buzzer and vibration are activated as follows:
LEDs:
Blue LEDs: torque result between Rundown complete torque and Torque min.
Green LEDs: torque result between Torque min and Torque max.
Red LEDs: torque result over Torque max.
Buzzer
Two beeps indicate the end of the operation; if the final result is in the red area, the signal in continuous.
To stop the buzzer, start a new tightening operation or press a button on the tool controller.
Vibration:
Stays active until the torque applied is released.
