System Overview
MWR-TA and Charging Cradle MWR User Guide
SYSTEM OVERVIEW
The MWR (mechatronic wrench) is based on a mechanical click-wrench combined with an electronic
torque transducer.
Torque
Angle / Time
The MWR-TA are equipped with the ISM band radio interface (characterized by a frequency equal to 868
MHz / 915 MHz) for wireless connection with Focus 60 / Focus 61.
2.1
Applications
The MWR-TA works with the Focus 60 / Focus 61, which defines the tightening programs for the MWR.

Battery / Charging Cradle MWR
A rechargeable NiMH AAA battery 1.2 V 1000mAh provides power to the MWR-TA.
(positive pole)
Front cap
To install/remove the rechargeable AAA battery, remove the front cap (shown in the figure above) by
using a flat screwdriver.
To power on the MWR-TA, insert the battery (with the correct polarity) into the related case.
WARNING: Never try to recharge non-rechargeable batteries. Such batteries cannot only leak out
during charging attempts, but can also explode, which can lead to destruction, fire risk and to
injuries.
Connect the Charging Cradle MWR to
the AC power in order to recharge the
battery. Then insert the MWR-TA into
the Charging Cradle MWR, as shown in
the picture on the right.

This indicates that the wrench sets the

System Overview
If the MWR-TA is in charging mode, the yellow LED of the MWR-TA is on and the Status LED of the
Charging Cradle MWR is flashing (green colored). When the charging process of the MWR-TA is
complete, the Status LED of the Charging Cradle MWR is constantly on (green colored).
If there is no wrench in the cradle then the cradle will be in standby mode, which is visualized by a blue
lightened status LED.
Below is a table that summarizes the LEDs behavior of the Charging Cradle MWR:

The support of the Charging Cradle MWR is intended for the MWR-85 TA and MWR-200 TA. There are
three holes in the support of the Charging Cradle MWR. As there are only two holes in the housing of the
Charging Cradle MWR, you will have two possible positions to mount the support on the housing. The
positions on the support arm are marked with an indicator for MWR-85 TA and MWR-200 TA to find the
right position.
If MWR-85 TA and MWR-200 TA are charged in the Charging Cradle MWR without the support, there is
a risk that the wrench/cradle can “flip” to the left side because of the length and weight. If this happens,
the wrench cannot be charged correctly.
In addition, if e.g. an MWR-200 TA has an end fitting which is inserted into the wrench, it will flip to the
left side almost every time. The charging process of the wrench is then affected in a negative way.
2.4
MWR-TA LEDs
The MWR-TA has three sets of LEDs (refer to the following figure):

Click-Torque Adjustment
MWR-TA Operations
Do the following procedure in order to adjust the mechanical click-torque of the MWR-TA:
1. Insert the Setting key MWR/CWR in the MWR-TA and handle it as shown in the following figure:
Setting key
MWR/CWR
2. Unlock the MWR-TA torque regulation system; then adjust the torque. Finally, lock the torque
regulation system.
Clockwise → Increase
torque
Counterclockwise → unlock the
torque regulation system.
Clockwise → lock the torque
regulation system.
Counterclockwise →
Decrease torque
NOTE: Please ensure that the torque regulation system is locked properly after adjusting the
mechanical click-torque. After locking the torque regulation system, it is highly recommended
to perform at least 10 clicks to verify the mechanical click setup.
NOTE: The label printed on each MWR-TA (see the following figure) indicates the torque
range of the MWR-TA:

Handling
3.2.1
Correct handling
•
The screw should be tightened in even strokes.
•
The closing speed should be chosen so that when
the click occurs an immediate interruption of the
tightening process is possible.
•
The operation of the torque wrench must be carried
out by the middle of the handle.
•
The force should be one-handed, uniform, parallel
and applied in the last phase without interruption
until the tool clicks.
•
The achievement of the set value (Click) is clearly
heard and felt.
MWR-TA and Charging Cradle MWR User Guide
NOTE: After the automatic release (click), the wrench must not be moved further.

•
Wrong handling
Having the thumb on the tube will influence the Click value!
