Overview
The Tensor system
The Tensor system consists of a range of tightening tools powered by brushless electric motors and differ-
ent drive units.
Motors are available in different sizes. All tools are protected from overheating of the motor. Electrical pro-
tection 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-shoot-
ing 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.

Operation
Ergonomic guidelines
Consider your workstation as you read through this list of general ergonomic guidelines and see if you can
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 convenient reach range by determining where parts or tools should 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 reducing 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.
■Make sure to take frequent breaks.
■Avoid extreme arm or wrist postures, particularly for operations requiring a degree of force.
■Adjust for convenient field of vision by minimizing movement of the eyes and head during the work
task.
■Use the appropriate lighting for the work task.
■Select the appropriate tool for the work task.
■Use ear protection equipment in noisy environments.
■Use high-quality inserted tools or 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 wheel is either bent or if it is not guided properly. Make sure to
use the correct flanges for cut-off wheels and avoid bending the wheel during cut-off operation.
■When drilling:
The drill might stall when the drill bit breaks through. Makes sure you use support handles if the
stall torque is too high. The safety standard ISO11148 part 3 recommends using something to ab-
sorb the reaction torque above 10 Nm for pistol grip tools and 4 Nm for straight tools.
■When using direct-driven screw or nutrunners:
Reaction forces depend on tool setting and joint characteristics. The ability to bear reaction forces
depends on the operator’s strength and posture. 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.
■Use dust extraction system or mouth protection mask in dusty environments.
Operating instructions
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 EN ETVST101-370-20F
14 © Atlas Copco Industrial Technique AB - 9836 8433 01
Troubleshooting
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.
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 re-
suming operation. Check that the wiring on the remote start connector is correct. For further information
see 9836 2258.
If the tool becomes very hot
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 correc-
tions are not enough, choose a tool of the next higher capacity.
