Overview

• The Tensor System
• Technical Product Data

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.

Socket Release Function

It is recommended to use the socket release function on all the ETP ST101 tools. When the function is enabled, the socket rotates backwards 3° after a completed tightening. The aim is to reduce tension on the reaction bar and to make it easier to remove the tool.

The socket release function is turned on from the controller.

On Power Focus 4000:

• Push the Prog button

• Use the navigation buttons to follow the path > Pset > Programming+ > Options > Socket release > Mode On

Tool Display

The tool display is turned on from the controller.

On Power Focus 4000:

• Push the Prog button

• Use the navigation buttons to follow the path > Tool > Configuration > Accessory bus > ST bus > Mode

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.

Installation Instructions

• Fitting of the Tool Cable

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.

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

Check the rotational direction of the tool before start! A start in an unexpected rotational direction can cause bodily injury or property damage. Moving parts can crush and cut.

• Make sure that the rotational direction of the tool is correct before starting the tool.

• Keep hands and fingers away from moving parts.

Dual Trigger

Dual trigger (Recommended to use during operation)

WARNING

Crushing Hazard

The Dual trigger forces the user to use both hands to operate the tool. If not used, the operator can accidentally start the tool while adjusting the crowfoot, thus resulting in a serious hand injury.

• Make sure the tool cannot be started once the Dual trigger has been released.

• Always test the tool by first releasing the trigger of the Dual trigger, then push the trigger of the tool. If the tool starts; stop working.

Operating

Make sure that the tool is in correct working order and that the controller is correctly programmed to avoid unexpected behaviour from the tool, which may result in operator injury.

Check that the tool is in the correct running direction by looking at the function light situated above the tool handle, by turning the reverse ring (only for ETV/ETD DS or by turning the arm on the trigger knob (only for ETP DS).

The soft-start function facilitates entering the screw head and thread.

The duration of the soft start is adjustable, see the manual for the drive unit.

Troubleshooting

• Overheated Tool
• Power Focus 3000/4000
• Power Focus 600/6000

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.

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.
