# Impulse Single Step Tightening Program

## Rundown

Parameter name | Condition | Description | Default value
--- | --- | --- | ---
Rundown speed |  | Selected by radio buttons. Rundown speed can be selected between Max or Manual. | Max
Rundown speed | Rundown speed = manual | Specifies the tool speed during the rundown step. |
Rundown time limits |  | Selected from a shortcut menu: Off:Rundown time limits is turned off. From Trigger: Rundown time limits is turned On. The system starts to monitor the time as soon as the tool trigger is pressed and reports if the time limits are violated. From torque: Rundown time limits is turned On. The system starts to monitor the time from the specified torque value and reports if the time limits are violated. | Off
Rundown time monitoring torque | Rundown time limits = from torque | Torque value from where Rundown time limits monitor starts. |
Time min | Rundown time limits = On | Minimum allowed time for rundown. | 10ms
Time max | Rundown time limits = On | Maximum allowed time for rundown. | 5000ms
Rundown pulse limits |  | Selected from a shortcut menu: Off:Rundown pulse limits is turned off. From Trigger: Rundown pulse limits is turned On. The system starts to monitor the pulses as soon as the tool trigger is pressed and reports if the pulse limits are violated. From torque: Rundown pulse limits is turned On. The system starts to monitor the pulses from the specified torque value and reports if the pulse limits are violated. | Off
Rundown pulse monitoring torque | Rundown pulse limits = from torque | Torque value from where the Rundown pulse limits monitor starts. | 2.5Nm
Pulses min | Rundown pulse limits = On | Minimum number of pulses to reach the target. | 2
Pulses max | Rundown pulse limits = On | Maximum number of pulses to reach the target. | 50
Rundown complete torque |  | Defines the torque value for when snug is reached and rundown is completed. | 5Nm

## Tightening

Parameter name | Condition | Description | Default value
--- | --- | --- | ---
Target torque |  | Final target torque for the tightening. |
Pulse Energy |  | The Pulse energy delivered in the action pulse expressed in a percentage of the maximum energy the tool can deliver in each pulse. |
Residual torque correlation factor |  | The term Residual torque correlation factor is similar to a calibration and adjusts between the dynamic torque, measured in the electrical tool, and the residual torque, measured by a control tool. | 100%
Torque limits |  | Selected by radio buttons. Limits can be Automatically or Manually selected |
Torque min | Torque limits = manual | Minimum torque for the step. |
Torque max | Torque limits = manual | Maximum torque for the step. |
Time limits |  | Selected from a shortcut menu: Off:Time limits is turned off. From rundown complete: Time limits is turned On. The system starts to monitor the time as soon as rundown complete is reached and reports if the time limits are violated. From torque: Time limits is turned On. The system starts to monitor the time from the specified torque value and reports if the time limits are violated. | Off
Time monitoring torque | Time limits = from torque | Torque value from where the Time limits monitor starts. |
Time min | Time limits = On | Minimum allowed time for tightening. | 10ms
Time max | Time limits = On | Maximum allowed time for tightening. | 1000ms
Pulse limits |  | Selected from a shortcut menu: Off: No pulse limit monitoring. From rundown complete: The monitoring starts when the Rundown complete torque is reached and reports if the number of pulses is outside the limit. From torque: The monitoring starts when the specific torque value is reached and reports if the number of pulses is outside the limit. | Off
Final pulse monitoring torque | Pulse limits = from torque | Torque value from when the pulse limits are monitored. |
Pulses min | Pulse limits = on | Minimum number of pulses to reach the final target. | 2
Pulses max | Pulse limits = on | Maximum number of pulses to reach the final target. | 50
Premature torque loss detection time |  | A constant increase in torque is assumed when moving from rundown to tightening. A socket slip of, or a broken screw head can cause the torque decrease. This may be detected in a monitoring window. | 200 ms
