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. |
Program start | Torque value from which the tightening operation starts. |
Torque min | Lower torque limit. |
Torque max | Higher torque limit. |
Maximum torque 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 | This parameter is not editable. |
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 Program start after reaching the 3rd percentage. |
Ratchet time | Starts when the torque goes below the Program start 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 | Program start |
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:
White LED: activated when the torque value goes over the smartHEAD's Min load value.
First, second and third radial gradient LEDs turn green in sequence when the three thresholds defined for the tool in use are reached.
For further information, refer to Tool LEDs.All three radial gradient LEDs green: torque between Torque min and Torque max.
All three radial gradient LEDs red: torque over Torque max.
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 Program start 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 behave according to the configuration of Result Indicator and Duration defined for the tool in use.
For further information, refer to Tool LEDs.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.
