# Overview

# General Description

Powered by a new battery generation from Atlas Copco, Tensor SRB Cordless Nutrunner delivers one-handed operation with accuracy, traceability and flexibility. The SRB reports wirelessly to the Power Focus 6000 system and takes full advantage of Virtual Stations, able to perform low reaction strategies as a Turbo Tight and Tensor Pulse, and traditional strategies as the two steps. The Tensor SRB is ideal for low toque application where the reaction force hits the operator wrist. It is light weight and has a great balance – ergonomically designed to prevent operator fatigue.

# System Functionality

The POWER FOCUS system sends the tightening program and the batch size to the tool, where it is stored and executed. The tightening result is then sent back to the POWER FOCUS. See schematic figure below.

The tool has the same basic functionality as other tools, but due to the nature of the wireless communication, where the tightening data is stored in the tool, all features in the POWER FOCUS software may not be available for this tool.

# Installation

# Installation Requirements

# Installation

For installation guideline, see Power Focus 6000 user guide.

# Setup Quick Guide

When using the Tensor Pulse strategy shown here, the tool will calculate and install dynamic torque.

The Residual Torque Correlation Factor (RTCF) is used to translate installed dynamic torque to static torque. During the setup of parameter settings the torque installed may be higher or lower than presented on the POWER FOCUS display screen. The RTCF affects the presented value, make sure to check the residual torque with an ST Wrench or similar if the joint settings are done with parts in ongoing production.

1. Start with setting the default parameters

   Parameter | Default
   --- | ---
   Target torque | Specified torque required
   Run down speed | Max
   Pulse energy | 80%
   Reaction Force Turning Factor (RFTF) | 40%
   Residual Torque Correlation Factor (RTCF) | 100%

   Settings that use 4-8 pulses to install the torque will give the best mix of accuracy, speed, and ergonomic.

   - Always do the settings on the intended joint.

   - Reusing the same joint for many tightenings may affect the result.

2. Adjusting the run down speed

   1. Choose the hardest joint in the batch and set the target torque to the specific torque required.

   2. Tighten the joint with standard POWER FOCUS settings.

   3. Check the torque and the number of pulses.

   4. If needed, decrease the run down speed down to 800-1200 rpm to achieve at least 4 pulses.

3. Adjusting the pulse energy

   1. Choose the softest joint in the batch and set the target torque to the specified torque required.

   2. Tighten the joint with standard POWER FOCUS settings with adjusted run down speed.

   3. Check the torque and the number of pulses.

   4. Increase pulse energy up to 100% to achieve maximum 8 pulses.

4. Adjusting the RTCF

   1. Choose a joint in the batch and set the target torque to the specified torque required.

   2. Tighten the joint with standard POWER FOCUS settings with adjusted run down speed and pulse energy.

   3. Use an ST Wrench or similar to check the residual torque.

   4. Do a number of tightenings to check and change the RTCF, see Power Focus 6000 Configuration manual. The torque shown on the POWER FOCUS should match the torque shown on the ST Wrench.

5. Tighten a number of joints with the new RTCF to see if required results are met. If the tool does not perform as intended, redo steps 2 through 4 to fine tune the setup.

6. Tighten as many joints as needed to check the tool capability on the intended joint.

# Installation Instructions

# Torque Adjustment

For installation of the torque adjustment, see Power Focus 6000 Configuration manual.

The torque adjustment factor is stored in non-volatile memory in the tool. Any changes made to the torque adjustment factor in the POWER FOCUS 6000 will update the stored value in the tool.

# Rapid Backup Unit

The Rapid Backup Unit (RBU) has the form factor of an SD card. The RBU contains all the current network configurations and settings. During the installation and configuration some of the parameters are saved on the card. In case of a failure, it is a quick task to remove the card and put it into a new tool and all functionality remains the same.

When the RBU is transferred from one tool to another, the new tool will be updated to the software on the card. Since there is a chance of loss of data during the update procedure, it is good practice to make sure the new tool is already running the same software version as the old tool, to minimize the risk of data loss.

This RBU can not be used for anything but storing the tool configuration data and software. Reformatting the card, as well as manipulating the data on the card through other means than ToolsTalk Service 2, will result in an unusable card.

Note that the saved results associated with the tool will be lost when the RBU is transferred to another tool.

The MAC-address is associated with the RBU, not with the tool itself. When transferring a card to a new tool, the tool's MAC-address will therefore be the RBU's MAC-address.

# Tool Conversion

When converting a tool (for example, by changing the front part), you are required to update the tool information in order to reflect the changes made to the tool. For more information see ToolsTalk Service 2 User Edition user guide

WARNING

Risk of injury

Tool modifications, when not done properly, can cause bodily injury, damage to the tool, or produce undesired results, due to the altered characteristics of the tool.

- Check the tool's max torque after modification

When connected to ToolsTalk Service 2 you will not be prompted to change the tool information. To change the tool designation to match the tool conversion, perform the same steps as those for spare part replacements. Use the tool designation of the new part to update the tool.

Since the tool has been converted, the tool information stored on the tool will no longer match the tool designation on the tool sign.

# Attaching and Removing the Battery

1. Attach the battery to the tool and make sure that it is fastened correctly. The battery can be attached pointing forward or backward to get the best accessibility and balance.

2. To remove the battery, press the button on the battery and push it out.

# Initial Configuration

# Tool Configuration

To configure the tool, see Power Focus 6000 Configuration manual or ToolsTalk Service 2 User Edition user guide.

# Tool Calibration

For information on tool calibration for this tool, see Power Focus 6000 Configuration manual or ToolsTalk Service 2 User Edition user guide.

# Operation

# Ergonomic Guidelines

Consider your workstation as you read through this list of general ergonomic guidelines to identify areas for improvement in posture, component placement, or work environment.

- Take frequent breaks and change work positions frequently.

- Adapt the workstation area to your needs and the work task.

  - Adjust for a convenient reach range by determining where parts and tools need to be located to avoid static load.

  - Use workstation equipment such as tables and chairs appropriate for the work task.

- Avoid work positions above shoulder level or with static holding during assembly operations.

  - When working above shoulder level, reduce the load on the static muscles by lowering the weight of the tool, using for example torque arms, hose reels or weight balancers. You can also reduce the load on the static muscles by holding the tool close to the body.

  - Take frequent breaks.

  - Avoid extreme arm or wrist postures, particularly during operations requiring a degree of force.

- Adjust for a convenient field of vision that requires minimal eye and head movements.

- Use appropriate lighting for the work task.

- Select the appropriate tool for the work task.

- In noisy environments, use ear protection equipment.

- Use high-quality inserted tools and consumables to minimize exposure to excessive levels of vibration.

- Minimize exposure to reaction forces.

  - When cutting:

    A cut-off wheel can get stuck if the cut-off wheel is bent or not guided properly. Use the correct flange for the cut-off wheel and avoid bending the cut-off wheel during operation.

  - When drilling:

    The drill might stall when the drill bit breaks through. Use support handles if the stall torque is high. The safety standard ISO11148 part 3 recommends using a device to absorb a reaction torque above 10 Nm for pistol grip tools and 4 Nm for straight tools.

  - When using direct-driven screwdrivers or nutrunners:

    Reaction forces depend on the tool settings and joint characteristics. Strength and posture determine the amount of reaction force that an operator can tolerate. Adapt the torque setting to the operator's strength and posture and use a torque arm or reaction bar if the torque is too high.

- In dusty environments, use a dust extraction system or wear a mouth protection mask.

# Configuration Instructions

# Tightening Programs

Assigning tightening programs and altering tightening program parameters is done through the controller the tool is paired with.

For more information, see Power Focus 6000 Configuration manual.

# Operating Instructions

# Optimizing the Performance of your Pulse Tool

It is not recommended to use extensions with pulse tools. Extensions cause vibrations, which in turn may cause wear on the tool, longer tightening time, limited accuracy and difficulty reaching maximum torque. If an extension is necessary due to accessibility constraints, it should be as short as possible. Guided sockets or extensions are strongly recommended.

## Recommended Number of Pulses

A Pulse tool well suited for your application should reach the target torque (with shut off) within 5-20 pulses. The number of pulses it takes for the tool to reach target torque can be measured with an analyzer. The tightening time can also be used a guide to know if the tool is appropriate for your application:

- ≤ 1 second for tools up to 30 Nm

- ≈ 1 second for tools up to 80 Nm

- ≈ 2 seconds for tools up to 150 Nm

- ≈ 5 seconds for tools up to 450 Nm

- ≤ 10 seconds for tools up to 850 Nm

If the target torque is achieved with less than 5 pulses (= short tightening time), the torque scatter will increase and it can be difficult to adjust to the right level, especially on hard joints.

If the target torque is achieved with more than 20 pulses (= too long tightening time) the wear will increase and more frequent oil filling and service will be required. Too long tightening time, in combination with high production rate, may also result in excessive heating of the oil. In that case the power will decrease with longer tightening time and sometimes no shut off.

If the target torque is achieved with less than 5 pulses this can be fixed by:

- Lowering the power setting during tightening.

- Reducing the rundown speed.

Changes of power settings and/or rundown speed may affect the torque accuracy.

If the target torque is achieved with more than 20 pulses this can be fixed by:

- Increasing the power setting.

- Increasing rundown speed.

Changes of power settings and/or rundown speed may affect the torque accuracy.

# LED Indicator Flash Patterns

Apart from the LED flash patterns determined by the controller, there are a number of standard flash patterns for the tool LED indicators.

The table below provides an overview of the standard flash patterns.

LED indicator | Light behavior | Status
--- | --- | ---
