2.1 Wireless devices network

The electronic position indicators DD51-E-RF is compatible

with Elesa wireless network which allows electronic position

indicators to communicate with a PLC via radio.

Elesa wireless network is made by the following components:

- One control unit UC-RF

- Max 36 device as DD51-E-RF, DD52R-E-RF or MPI-R10-RF

The control unit UC-RF is provided with a standard interface

for the most common industrial busses to be connected to

the PLC and allows the information transmission between

the PLC and the electronic position indicators DD51-E-RF.

The control unit UC-RF exchanges information with

the electronic position indicators DD51-E-RF via radio

frequency and allows the setting of the target position and

the control of the current position of each indicator, directly

from the PLC.

WARNINGS! Read the control unit UC-RF instructions

for more details regarding its configuration.

3 Assembly

1. Drill a Ø 6x10 mm hole in the body of the machine with

a 22 mm centre distance from the shaft to fit the rear

referring pin.

2. Fit the indicator onto the spindle and make sure that

the referring pin fit the hole.

3. Clamp the boss to the

spindle by tightening the

grub screw with hexagon

socket and cup end,

according to UNI 5929-85.
