Impulse Single Step Tightening Program

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

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.
