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.

Installation
Installation Instructions
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
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
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.
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.
