INFORMATION FOR USERS
European Directive 2006/66/CE
WASTE DISPOSAL OF DEAD REMOVABLE BATTERIES:
The symbol of the barred waste bin carried on the battery or on the package indicates that the
battery is included in the European Directive 2006/66/CE and therefore at the end of its useful
life it must be disposed of separately from other waste. Adequate differentiated waste collection
and successive environmentally compatible disposal contributes to prevent negative effects on
the environment and on human health.
For Countries outside of the European Union, collection and disposal must be carried out in
compliance with the Standards in force or with other Laws of that Country regarding treatment
of obsolete batteries.
For information regarding the type of used batteries and any replacement methods without
danger for the user, refer to the equipment instruction manual.

INFORMATION FOR USERS
concerning the terms of the National Legislation enforcing the Directive 2012/19/EU on
waste electrical and electronic equipment (WEEE).
The wheelie bin symbol with a cross through it on t
he equipment or its packaging indicates that
the product must be disposed of separately from other waste materials at the end of its working
life.
If the user wishes to dispose of this equipment, he/she must do so in accordance with the
applicable National
regulations governing the separation of the unit into its waste materials at the
end of its working life.
Separating waste materials correctly before submitting the equipment for recycling, treatment and
environmentally compatible disposal can help to pr
event potentially negative effects on health
and the environment, as well as making it easier to reuse and/or recycle its constituent materials.
Failure to dispose of this product in accordance with these indications is punishable in
accordance with the applicable laws.

2. DESCRIPTION OF THE SYSTEM COMPONENTS
The MIDA WRS system with radio transmission consists of one or more WRP transmitters (available in
WRP45 and WRP60 versions) or WRTS transmitters that transmit the data to a receiver with integrated
interface, directly connected to the machine tool’s CNC.
Such a system is able to handle two types of applications (using the same WRI Receiver and a choice of up
to 4 WRP and WRTS devices):
•WRI + WRP
(probing cycle)
•WRI + WRP + WRTS
(probing cycle + tool setting)
The receiver (WRI) is able to handle both the applications through its own integrated interface, suitably
programmed.
Below there are listed the main components of the system:

3.1.1 Signal Transmission
The radio transmission system consists of one or more touch probes/transmitters and a receiver. Upon the
system installation and configuration the signal is sent from receiver to transmitter, while during the use the
touch and low battery signals are sent from transmitter to receiver.
3.1.1.1 Transmission condition
The communication between receiver and transmitter (bidirectional) may take place through 2 types of radio
transmission:
1. Completely visible, with a direct path.
2. Through reflections, when transmitter and receiver are not in direct visibility, but communicate
through reflection on the walls, floor and the metal parts present in the surrounding area.
To optimize the communication we suggest to follow the directions reported in section 4.11 on page 52.

4. INSTALLATION
4.1 WRP45 - Assembling the Transmitter
[
N.B.:
In most cases the transmitter is assembled when it is supplied, and it should not be disassembled
for any reason in order to avoid compromising the seal.
WARNING
In order to
ensure the correct tightening torque
between the parts, we recommend using two
wrenches (see Figure 4-1
) and applying the
tightening torque indicated in chart in.
Figure 4-1
. Example showing how to use
two assembly wrenches to tighten the parts.
Fitting the probe – transmitter
Proceed as follows for fitting or removing the probe on/from the transmitter:
WARNING
When fitting the probe, make sure that th
e seal rings are in very good conditions and correctly
positioned in their own seat.
TT30 probe
•Screw the flange (A2) to the transmitter with the wrench supplied with the equipment.
•Screw the probe (B2) to the flange using the wrench supplied.
TT25 - T25 - T25P probe
•Screw the flange (A1) to the transmitter with the wrench supplied
•Screw the probe (B1) to the flange using the wrench supplied.
After completing the operation, it is necessary to align the system (see section 4.3 on page 26).

Proceed as follows for fitting or removing the probe on/from the transmitter:
•Screw the probe (B1) to the transmitter (A1) using the wrench supplied.
After completing the operation, it is necessary to align the system (see section 4.4 on page. 27)

4.2.1 Inserting the extension for probes (optional accessory)
The extension is inserted between probe and transmitter to increase the measuring depth of the system.
Proceed as follows to insert the extensions:
Extension for T25 - TT25 - T25P probe
•Remove the probe from the transmitter with the special wrench supplied with the equipment.
•Insert the extension (A1) with the relevant seal rings between probe and transmitter.
•Tighten the unit by means of the wrench supplied.
Figure 4-4. Insertion of the extension for T25 - TT25 - T25P probes.
[
N.B. :
There are no extensions for the TT30 probes.
WARNING
When inserting the extensio
n make sure that the seal rings are in very good conditions and
correctly positioned in their own seat.
After completing the operation, it is necessary to align the system (see section 4.3 on page. 26)

4.2.2 Fitting the stylus
Here there is described the procedure for fitting the stylus on the probe installed on a transmitter.
[
N.B. :
The procedure described here after foresees the use of a crash-
protection pin. This pin, placed
between stylus and p
robe, has the aim of safeguarding the probe in case of accidental impacts
on the stylus.
The crash protection pin is suggested for steel stylus. With ceramic stylus the probe
safeguarding is guaranteed by the fragility of the stylus.
Proceed as follows to fit the stylus on the probe:
•Fit the crash protection pin (A) on the probe (B).
•With the wrench (supplied with the equipment) hold down the stylus holder (C) of the probe to avoid
damaging it while tightening the pin. With the other wrench act in position (D) to tighten the crash
protection pin (A).
•Screw the stylus (F) on the crash protection pin (A). Use a wrench to hold the pin down, and the
other one to tighten the stylus.
•Insert the guard (E), making it slide along the stylus until the crash protection pin (A) is covered. This
guard has the task of holding the stylus in case of breakdown of the crash protection pin
If no crash protection pin is used, screw the stylus directly on the probe; use a wrench to hold down the
stylus holder (C) and the other one to tighten the stylus.
Figure 4-5. Fitting the stylus.
WARNING
To guarantee constant, high-
quality results we recommend using ceramic or carbon fibre
styluses.
[
N.B. :
When choosing the components of the stylus, we recommend:
•Using the smallest number of components possible.
•
Selecting the greatest possible stylus diameter, while ensuring the total length is reduced to a
minimum.
•In the case of applications that incl
ude the use of a shear pin, we recommend selecting the
sturdiest solution and carrying out the appropriate metrological tests before using it.
