Applications

The MWR-25 TA is a mechanical click-wrench combined with an electronic torque transducer.

The MWR-25 TA are equipped with the ISM band radio interface (characterized by a frequency equal to 868 MHz / 915 MHz) for wireless connection with Focus 61.

The MWR-25 TA works with Focus 61, which defines the tightening programs for the MWR-25 TA.

For more information about the configuration and the use of the MWR-25 TA, refer to the Focus 61 User Guide.

LEDs

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.

Wrong handling

• The operation of the MWR-25 TA must be carried out by the middle of the handle.

  

• Pull / Push only in the tightening direction.

• Do not touch the body of the MWR-25 TA during tightening operations. Positioning the thumb on the tube alters the click value!

  

• Do not hold the body of the MWR-25 TA during tightening operations. The operation of the MWR-25 TA must be carried out by the middle of the handle.

  

Correct handling and click tightening

• The screw should be tightened in even strokes.

• The closing speed should allow an immediate interruption of the tightening operation as the MWR-25 TA clicks.

• The operation of the MWR-25 TA must be carried out by the middle of the handle.

• The force should be one-handed, uniform, parallel and applied with no interruptions until the tool clicks.

After the automatic release (click), the MWR-25 TA must not be moved further.

Operating Instructions

• Adjusting the click-torque
• Tightening Test

Adjusting the click-torque

Tightening Test

The Focus 61 sends the tightening program (Pset and Job) to the MWR-25 TA.

For more information on the configuration and the use of MWR-25 TA, refer to the Focus 61 User Guide.

When the MWR-25 TA receives the tightening program and the wrench is ready for use, the blue LED flashes.

Load the MWR-25 TA following the direction of the arrow as shown on the label on the MWR-25 TA body (see the figure below):

During the measurement (MWR-25 TA is loaded with torque), the yellow LED flashes.

At the end of each tightening, the LEDs are alight according to the test result:

• Green LED: Tightening OK

• Red LED: Tightening NOT OK
