Efficient Machine Set-Up
The system allows to save time during the format
alignment process.
• Once the set-up profile has been called up by PLC,
UC-RF control unit transmits the target position to
each DD52R-E-RF position indicator.
• The current / target position is displayed on LCD
display of DD52R-E-RF indicator.
• The operator manually sets the position of the
spindles following the arrow displayed on LCD display
(clockwise/anti-clockwise rotation).
• Once all the spindles are correctly set, UC-RF control
unit communicates to PLC of the machine that the
set-up has been completed.
The wireless system, consisting of UC-RF control unit and up to 36 electronic position indicators DD52R-E-RF,
is designed for an efficient manual spindle positioning.
DD52R-E-RF position indicators (Elesa Patent) are networked to UC-RF control unit via radio frequency (RF),
so that connecting cables are not required for an easy and quick installation.
Current and target positions are transmitted via RF, from and to the control unit, facilitating machine set-up.
Easy installation
Up to 36 position indicators can be networked
(via radio frequency) to the control unit.
No cables required to connect the position indicators to
the control unit.
Safety
The system prevents the machine from starting up until
the machine set-up is completed, avoiding production
issues.

- reading orientation (right or reverse).
KEYBOARD
Polyester membrane. Resistant to solvents, alcohol, acids, alkalis.
INTERNAL GASKET
O-ring front sealing in NBR synthetic rubber, between the case and
the boss.

protection class, see EN 60529 table obtained by means of a brass
bushing with double seal ring inside the rear cavity of the base.
ASSEMBLY INSTRUCTIONS
1. Drill a Ø 6 mm by 10 mm hole in the body of the machine with a 30
mm centre distance from the spindle to fit the rear referring pin.
2. Fit the indicator onto the spindle and make sure that the referring

FEATURES AND APPLICATIONS
DD52R-E-RF position indicators, with battery power supply, can be
used on passing through shafts in any position to provide the reading
of the absolute or incremental positioning of a machine component.
- The 6-digit display of 12,0 mm height ensures excellent readability
even from a distance and from different viewing angles.
The window in transparent technopolymer protects the LCD display
against accidental shocks.
- The high protection degree, IP 65 or IP67, makes the indicator suitable
for applications that require frequent washing, even with intense
water jets.
- In the operating mode, by using the 4 function keys, it is possible
to select the incremental or the absolute mode, the unit of measure
(mm, inches or degrees), reset the absolute counter or load a preset
source value and the preset offset value.
- In the programming mode, through the 4 function keys, it is possible
to program the reading after one revolution of the shaft, the direction
of rotation, the display orientation, the resolution (number of decimal
digits displayed), the source value and the offset value, the max.
speed of rotation and set the functions of the keys for the different
options available.
- The internal battery ensures long battery life (over 3 years). A special
symbol appears on the display when it is necessary to replace the
battery. The replacement can be performed easily by removing the
front cover (Fig.1), without disassembly of the indicator from the
control shaft and without the loss of configuration parameters.
QUICK POSITIONING SYSTEM
DD52R-E-RF indicators (Elesa Patent) are networked to the control unit
UC-RF via radio frequency (RF), constituting a wireless system for rapid
positioning of the machine parts (fig.2).
This system is particularly suitable for applications that require frequent
format changes, facilitating the correct adjustment of the target/current
position of the machine parts, also representing a safety system. In
fact, even if a single DD52R-E-RF indicator is not placed in the target
position, PLC doen't allow the beginning of the machine production
cycle, thus avoiding production issues.
The installation of the system is quick and easy as it does not require
the use of connecting cables between the control unit and the indicators.
