# Torque (Control) / Angle (control) AND

This strategy guides the operator in reaching the desired target torque and angle.

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. Must be ≥ smartHEAD Min torque value. If Program start = 0, its value is automatically set to the smartHEAD Min torque value.
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. Must be > Torque max.
Target torque | The torque target.
Trigger torque | Torque value from which the angle measurement starts (usually set to 50% of the Target torque). If Trigger torque = 0, its value is automatically set to the smartHEAD Min torque value.
Angle min | Lower angle limit.
Angle max | Higher angle limit.
Target angle | The angle target.
Torque units | This parameter is not editable.
Angle limit for rehit | If the Torque min value is reached within the specified angle, the message Joint already tightened is shown on the wrench display.
Stop condition | Select between Torque peak and Angle peak.
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. The parameter is stored in the RFID TAG of the end fitting tool. When extensions are not used, Torque correction coefficient = 1.
Angle correction | When extensions cause additional wrench bending, the wrench angle measurement can be compensated to show a more accurate angle value. To calculate the correction value, please refer to How to Calculate the Angle Correction. The parameter is stored in the RFID TAG of the end fitting tool. When extensions are not used, Angle correction = 0.
Batch size | Number of tightenings the batch will perform. Maximum value: 99. If Batch size = 0, the number of tightenings is infinite. If Batch size > 1, batch result OK only if all tightenings are OK.
Max consecutive NOK | Number of accepted consecutive NOK to have an OK result.
End cycle time | Starts when the torque goes below the Program start after reaching the 3rd percentage. Default value: 0.1 sec. Minimum value: 0.1 sec. Maximum value: 5 sec.
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. Default value: 5 sec. Minimum value: 0.1 sec. Maximum value: 30 sec.

Torque vs. Angle

A | Torque max | B | Target torque
C | Torque min | D | Trigger torque
E | Program start | F | Angle min
G | Target angle | H | Angle max

The green area defines the OK result area.

During the tightening operation, LEDs, buzzer and vibration are activated as follows:

- LEDs:

  - First radial gradient LEDs white (two directions): torque and angle over the 1st percentage (30% of the Torque min / Angle min).

  - Second radial gradient LEDs white (two directions): torque and angle over the 2nd percentage (60% of the Torque min / Angle min).

  - Third radial gradient LEDs white (two directions): torque and angle over the 3rd percentage (95% of the Torque min / Angle min).

  - All three radial gradient LEDs green: torque between Torque min and Torque max, angle between Angle min and angle max.

  - All three radial gradient LEDs red: torque over Torque max, or angle over Angle max.

  Torque Peak:

  Torque vs. Angle

  A | Torque max | B | Target torque
  C | 2nd percentage | D | 1st percentage
  E | Program start | F | Target angle
  G | Angle max |  |

  Angle Peak:

  Torque vs. Angle

  A | Torque max | B | Target torque
  C | Program start | D | 1st percentage
  E | 2nd percentage | F | Target angle
  G | Angle max |  |

- Buzzer:

  - The beep starts when the torque goes over the Program start value; the signal increases when the 1st percentage, the 2nd percentage, the angle and target values, and the Torque max are reached.
    If Angle peak is specified in the tightening program, the buzzer signal monitors the angle instead of the torque.

- Vibration:

  - Starts together with the third radial gradient LEDs.

Torque/angle results:

- If the torque/angle does not exceed the torque/angle limits, the result is taken at the Torque Peak or Angle Peak (as specified in the tightening program).

- If the torque/angle goes over the limit, the result is taken as follows:

  Torque vs. Angle

  A | Torque max | B | Torque min
  C | Trigger torque | D | Program start
  E | Angle min | F | Angle max
  G | When the Stop condition is set to Torque peak, and the torque (or both torque and angle) goes over the limits, the result is taken at the torque peak. | H | When the Stop condition is set to Torque peak, and only the angle goes over the limits, the result is taken at the angle peak.

  Torque vs. Angle

  A | Torque max | B | Torque min
  C | Trigger torque | D | Program start
  E | Angle min | F | Angle max
  G | When the Stop condition is set to Angle peak, and the angle (or both torque and angle) goes over the limits, the result is taken at the angle peak. | H | When the Stop condition is set to Angle peak, and only the torque goes over the limits, the result is taken at the torque peak.

At the end of the tightening operation, LEDs, buzzer and vibration are activated as follows:

- LEDs:

  - Blue LEDs: angle result between Program start and Torque min, or torque between Torque min and Torque max with angle below the Angle min.
    If Angle peak is selected in the tightening program, the Trigger torque value is used instead of the Program start value.

  - Green LEDs: torque and angle results within the minimum and maximum limits.

  - Red LEDs: torque result over Torque max, or angle result over Angle max.

- Buzzer:

  - Two beeps indicate the end of the operation; if the final result is in the red area, the signal is 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.
