System Overview

The MTRwrench 85 is a mechanical click-wrench combined with an electronic torque transducer. The tightening programs are configured and assigned to the wrench with the Power Focus 6000 or with the Power Focus 8, which communicate wirelessly with the MTRwrench 85 using the MWR-KIT as gateway.

For more information on how to manage and configure the MTRwrench 85, refer to MWR-KIT Product Instructions, Power Focus 6000 User Guide and Power Focus 8 User Guide.

Configuring Tightening Programs

The MTRwrench 85 tightening programs are configured and managed via Power Focus 6000 or via Power Focus 8.

To communicate with Power Focus and receive tightening programs, the MTRwrench 85 must first be linked to an MWR-KIT connected to the Power Focus.

If during operations the MTRwrench 85 goes out of radio range, the wrench will continue working with the last tightening program assigned by the Power Focus and can store up to 10000 results. Once the MTRwrench 85 is back within radio range, the Power Focus retrieves the collected results and communicates any potential changes applied to the assigned tightening program during the out-of-range period.

For more information on how to enable and manage the communication among the devices, refer to MWR-KIT Product Instructions.

For more information on how to configure tightening programs, refer to Power Focus 6000 User Guide or to Power Focus 8 User Guide according to the controller in use.

Tightening Strategies

This section provides an overview of the tightening strategies that are available to configure tightening programs to operate the MTRwrench 85.

For more information on how to configure tightening programs, refer to Power Focus 6000 User Guide or to Power Focus 8 User Guide according to the controller in use.

Torque Control Strategy

The Torque Control Strategy helps the operator achieve the desired target torque, without any angle reading.

The main parameters that define this strategy are the following:

Parameters with an asterisk are mandatory.

A	Change screw	E	Minimum Torque
B	Maximum Torque	F	Trigger torque
C	Final Torque	G	Tightening Program Start
D	Click Torque

A result is OK if the Click Torque is within the upper and lower torque limit values defined for the selected tightening program.

For more information on how to configure tightening programs, refer to Power Focus 6000 User Guide or to Power Focus 8 User Guide according to the controller in use.

Torque Control / Angle Monitor Strategy

The Torque Control / Angle Monitor Strategy helps the operator achieve the desired target torque while monitoring the angle.

The main parameters that define this strategy are the following:

Parameters with an asterisk are mandatory.

A	Change screw	G	Tightening Program start
B	Maximum torque	H	Angle measurement start (at Trigger Torque)
C	Final torque	I	Minimum Angle
D	Click Torque	J	Angle at Click Point
E	Minimum Torque	K	Maximum Angle
F	Trigger Torque

A result is OK if:

• the Click Torque is within the upper and lower torque limit values defined for the selected tightening program,

and

• the Angle at Click Point is within the upper and lower angle limit values defined for the selected tightening program.

For more information on how to configure tightening programs, refer to Power Focus 6000 User Guide or to Power Focus 8 User Guide according to the controller in use.

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. Always 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.

Turning On the Wrench

Once the MTRwrench 85 is on, the Progress LEDs on the HMI start blinking with white light show that a MTRwrench 85 requires a zerozero adjustment is required.

The Radio Communication LED on the HMI starts blinking to notify the MTRwrench 85 wireless communication is ON.

Turning Off the Wrench

Performing a Zero Adjustment

A zero adjustment is required in the following situations:

• After turning on the MTRwrench 85.

• After a minor overload of the transducer.

To perform a zero adjustment, proceed as follows:

Handling the Wrench

Correct handling:

• Tighten in even strokes.

• Hold the MTRwrench 85 by the middle of the handle when performing a tightening.

• Apply force only in the tightening direction.

• The force applied to the wrench must be one-handed, uniform, parallel and continue until the tool clicks.

• Keep a tightening speed that enables you to immediately stop tightening as soon as the MTRwrench 85 clicks.

Wrong handling:

• Do not apply any force to the wrench after the automatic release (click).

• Do not apply force to the wrench in any direction other than the tightening direction.

  

• Do not touch the body of the MTRwrench 85 during tightening operations. Positioning the thumb on the tube alters the click value!

  

• Do not hold the battery housing of the MTRwrench 85 during tightening operations.

  

Running Tightening Operations

The MTRwrench 85 can store up to 10000 results. If the wrench is turned off, or if it goes out of radio range, the results can be retrieved by the Power Focus once the MTRwrench 85 is on again, or when it is back within radio range.
