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, in-
terfering or tampering with the protection system voids all warranty and obliga-
tions 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 reg-
ular basis by pressing the trip-button. The EFP should switch off accordingly.

Service intervals
Service recommendations
Overhaul and preventive maintenance is recommended at regular intervals. See
the Preventive maintenance section for detailed information regarding over-
haul of your tool and specific parts. If the machine is not working properly, it
should immediately be taken away for inspection. At the overhauls, all parts
should be cleaned accurately and defective or worn parts should be replaced.

Installation EN ETDSL21-04-i06-PS

Installation
Installation requirements
Installation
Connecting 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.
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 > Ac-
cessory bus > ST bus > Mode
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 oafter 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+ > Op-
tions > Socket release > Mode On
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
• Security check that the cable type is correct
• 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.
• Security check 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
Ergonomics
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, compo-
nent 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 as-
sembly operations.
• When working above shoulder level, reduce the load on the static mus-
cles 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 requir-
ing 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 ex-
cessive 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 absorb 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 abil-
ity to bear reaction forces depends on the operator’s strength and pos-
ture. 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 cor-
rectly programmed to avoid unexpected behaviour from the tool, which may re-
sult 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.
The tool is equipped with signal lights,
• Green = OK tightening
• Yellow = Warning – low torque (not for ES)
• Red = Warning – high torque
• Orange = Function indicator (only for SL and DL)
• Blue = Function indicator (only for SL)

Service
Maintenance
Preventing ESD problems
The components inside the tool and controller are sensitive to electrostatic dis-
charge. To avoid future malfunction, make sure that service and maintenance is
carried out in an ESD approved work environment. The figure below shows an
example of an appropriate service work station.
Service instructions
Overhaul and preventive maintenance is recommended at regular intervals once
per year or after maximum 250.000 tightening depending on which occurs
sooner. More frequent overhaul may be needed if used at high torque, high cy-
cle rate or long tightening times. If the machine is not working properly, it
should immediately be taken away for inspection.
At the overhauls, all parts should be cleaned accurately and defective or worn
parts (i.e. O-rings) should be replaced.
Cleaning/Inspection
Clean all parts thoroughly in white spirit or similar cleaning agent. After the
cleaning, inspect all parts. Damaged and worn parts should be replaced.
