# Overview

# The Tensor System

The Tensor system consists of a range of tightening tools powered by brushless electric motors and different drive units.

Motors are available in different sizes. All tools are protected from overheating of the motor. Electrical protection system is based on an earth fault circuit brake, Earth Fault Protector (EFP). The EFP senses small current leakage (>30mA) and if leakage occurs, the drive is switched off (30ms). Changing, interfering or tampering with the protection system voids all warranty and obligations from Atlas Copco. Trouble-shooting and re-start of the system may only be carried out by an authorized person. Check the function of the EFP on a regular basis by pressing the trip-button. The EFP should switch off accordingly.

# Installation

# Installation Requirements

# Connecting the Tool

The tool should, via its correct Power Focus drive unit, be connected to the mains, 230V/50Hz alternatively 115V/ 60Hz, single phase. See instructions for your Power Focus drive unit.

# Grounding

If the tool is mounted in a handheld or hand guided fixture, the fixture should be connected to the drive using a separate 2.5mm2 grounding cable.

# Reaction bar

Adapt and use the torque reaction bar as follows:

In this Section

- 1 Shaping the reaction bar, Fig. A
- 2 Defining the bending point of the reaction bar, Fig. A
- 3 Bending, Fig. B
- 4 Assembly
- 5 Use

# 1 Shaping the reaction bar, Fig. A

The torque reaction bar must be shaped to fit a suitable fixed support. The point of contact for the reaction bar depends on the target torque for the tightening and the length of the socket.

Determine the minimum angle a according to the table below.

To avoid overloading of the bearings for the tool drive and of the reaction bar, the point of contact on the reaction bar (K) must be as far away from the tool centre line as possible, see Fig. A.

Torque (Nm) | 200 | 300 | 500 | 750 | 1000 | 1500 | 2000 | 3000 | 4000
Angle a (degree) | 46 | 59 | 50 | 45 | 55 | 38 | 41 | 40 | 50

# 2 Defining the bending point of the reaction bar, Fig. A

Use a piece of paper to make the drawing and measurements. Use a ruler and a protractor for accurate drawings.

- Determine the minimum angle a, according to the table.

- Determine the contact point (K) of the reaction bar. Make it as far away from the tool centre line as possible.

- Measure the resulting angle a, and make sure it is greater than the table entry for the selected torque.

# 3 Bending, Fig. B

Heat the spot to red colour.

It is recommended to concentrate the heat to the inside radius in order not to reduce the original width (W), see fig. B.

- After bending, allow to cool slightly in room temperature and then chill.

After bending, attach the accompanying warning sign to the reaction bar, see fig. C, and mark the side of the reaction bar that should be placed against the support in a suitable way.

# 4 Assembly

- Place the reaction bar in the wanted position on the machine.

- Tighten the nut to a torque of 70 Nm, 90 Nm or 100 Nm respectively.

- Check regularly that the lock ring is firmly secured.

# 5 Use

- Apply the reaction bar according to figure 4 – opposite the direction of the drive of the machine – before starting the machine.

- Never put your hand on or close to the reaction bar while the machine is being used.

# Installation Instructions

# Cable Management

## Fitting of the Tool Cable

- Make sure that the tool cable is of correct type.

- Align the cable connector using the two asymmetrically positioned heads on the connector to fit in the slots in the tool handle.

- Tighten the lock nut.

- Make sure that the connection is correct by pulling, pushing, and turning the cable connector (there should be no movement).

The tool has a built in electronic memory chip that will transmit the torque transducer calibration value and angle pulses to the POWER FOCUS/drive unit. Any changes made of these values in the POWER FOCUS while the tool is connected will be stored in the tool memory.

# 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.

# Operating Instructions

# General Instructions

The tool may only be used together with the associated torque reaction bar, which is adapted to the screw joint application concerned.

1. Attach the reaction bar to the tool and insert the retaining ring into the groove to hold the reaction bar in position.

2. Attach the socket to the square drive. Insert the locking pin through the socket and square drive according to the illustration.

WARNING

# Troubleshooting

# Power Focus 3000/4000

Is the POWER FOCUS switched on and in RUN mode? Check that the correct POWER FOCUS is used (ST31/ST32/ST61/STR31/STR61-Tensor3-7, ST81-Tensor8-9). Check the fuses for the drive part. Check Drive parameters, refer to the User Guide of the POWER FOCUS/ drive unit. Check the earth fault circuit breaker on the backside of the drive. Should it have tripped, make sure to find the primary fault before resuming operation. Check that the wiring on the remote start connector is correct. For further information see 9836 2258.

# Power Focus 600/6000

Is the unit switched on? Check the earth fault circuit breaker behind the front door. Should it have tripped, make sure to find the primary fault before resuming operation. Check that the wiring on the remote start connector is correct. For further information see 9836 4954/9836 7446.

# Overheated Tool

With proper adjustment the tool can handle any normal line jobs that an operator sustains. What can cause overheating are combinations of some factors: torque above rated, too low speed, too long ramp time (motor has to give high torque for a long time), very high prevailing torque, very soft joints, short cycle time. To correct, look over speed, ramp time, tightening strategy. One stage and Ergoramp are most heat conserving when applicable. Please refer to the User Guide of your POWER FOCUS. If the above corrections are not enough, choose a tool of the next higher capacity.
