System description

DD51-E 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.

Mechanical and electrical characteristics

Power supply| Lithium battery CR2450 3.0 V
Battery life| Up to 5 years

(3 years for RF version)

programmable (1)

WARNINGS!

Higher rotation speeds to 600 r.p.m. can be maintained for short periods of time.
The value of the max speed affects the battery life.

Wireless devices network

DD51-E-RF is compatible with the Elesa’s wireless network that allow electronic meters and indicators to communicate via radio with a PLC.
The Elesa’s wireless network is made by the following components:

One control unit UC-RF
Max 36 electronic position indicators or meter 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 transmission of the information between the PLC and the DD51-E-RF position indicators.
The UC-RF exchanges information with the DD51-E-RF via radio frequency and allows the setting of the target position and the control of the current position of each indicators, directly from the PLC.

WARNINGS! Check the UC-RF instruction for more detail regarding the configuration.

Assembly

Drill a Ø 6×10 mm hole in the body of the machine with a 22 mm centre distance from the shaft to fit the rear referring pin.
Fit the indicator onto the shaft and make sure that the referring pin fits into the hole.
Clamp the bushing to the shaft by tightening the grub screw with hexagon socket and cup end, according to UNI 5929-85.

P_OFS: direct programming of the compensation value (OFFS parameter)
OFF: the keys combination + is not linked to any function in the operating mode.

For programming the parameters listed above see parameter 0___0 of cap. 8.3.

Targets

DD51-E allow to set up to 32 target positions to store relevant machine configuration setting.

To program the targets:

selet tArGE in the main menu (see cap. 8.3)
select PrOGt (see cap. 8.4)
select the wanted memory location (PtG01 to PtG32) using the keys
press the key to select.
follow the instruction in cap. 8.1 to set the wanted value.

To load a target:

select tArGE in the main menu (see cap. 8.3)
select LOAdt (see cap. 8.4)
select the wanted target value (LtG01 to LtG32) using the keys
press the key to select.
The value of the selected target is shown.
Press again to confirm or press to go back to the target selection list.

WARNINGS!
When a target is loaded the unit of mesure cannot be change.

Reaching the target position

When a target is selected the device will suggest the direction of rotation of the shaft to reach the target by means of the symbols and

It is possible to set the tolerance of the target as absolute difference from the set value by means of the PtOLL parameter (see cap. 8)

The target position indicators will work, depending from the dir and PtOLL parameters, as in the following table:

T = set target
M = measured value
Toll = tolerance (see Ptoll)

| dir –o| dir o–
---|---|---
M < T – Toll|

If a target is selected, is possible to cancel it entering in programming mode and selecting the StoPt option.

Target display mode

The menu voice ____0 (see cap. 8.3) allows the user to choose one of the target following modes listed below:

dtArG (default): when a target is loaded, the display shows the actual absolute position and the indication to reach the target as explained before in cap. 7.5.1.
Pressing the key the set target position is shown.
dtoGo: when a target is loaded, the display shows the distance to the set target and the indication to reach the target as explained before in cap. 7.5.1.
If the target is not reached, the display blinks. Pressing the key the display shows the actual absolute position.
OFF: the key is not associated to any function in the operating mode.

Target tolerance

Set the value of Ptoll parameter to define the tollerance allowed for target (see cap. 8 for details).

RF version (DD51-E-RF)

Programming the network parameter (nEtid) and the channel parameter (nEtch)

The system radio network is defined by the following two parameters:

nEt id : id 00/99 (NetID = 03 is reserved and is not possible to be used)
nEt ch : ch 01/36

These parameters can be configured in the Radio menu of the indicator (see cap. 8) and must be set according to the PLC recipe to guarantee a perfect communication between UC-RF and DD51-E-RF.

Warning

For DD51R-E-RF with firmware release equal to 5.1 or higher, channel 1 is equivalent to channel 4 of the previous version. Consider it when used in old system with UC-RF with fw release lower than 5.1

Targets

Using DD51-E-RF, target positions can be sent from the PLC to the indicators through the control unit. When a target is set, the behaviour is the sameas decribed in cap. 7.5.

Programming mode

Press the key for 3 seconds to enter the programming mode. Depending on the setting of PASS parameter(see cap. 8.6.4), the system may require you to enter a password.

Press the key to scroll through the list of parameters and selct the wanted one pressing .
Press the key to exit the programming mode. The programming mode is automatically dropped after 30 seconds of inactivity.

Programming parameters with numeric values

Press the key to increase the flashing digit.
Press the key to select the next digit.
Press the key to confirm the value and go back to the list of parameters.

The numeric values of the parameters must be inserted taking into account the selected unit of measure.

When a parameter is changed from its stored value, confirming it, the display will show the message CHAnG.
When exiting from the programming mode, the parameter are stored in the internal memory. If a parameter was changed, the display will show the message StorE

Parameter value

The parameter value depends on the unit of measure and resolution set.

The value may change according to the resolutions of mm and inch.

Es.
If rES mm = 1 and res inch = 0.01
The max parameter in mm is -2539 ÷ 2539 because
if we convert the value in inch 2539 / 25.4 = 99.96 which is the max value visible on the display with the res inch = 0.01
In case the parameter was 2540 it would not be possible to show the converted value because 2540 / 25.4 = 100.00

Addittional features

Reset

To reset the device to the factory setup:

select the voice rESEt from the main menu (see cap. 8.3)
change the value from no to YES by pressing the key
press the key to confirm

Test LCD

The LcdtS voice in the main menu allow to switch on all the display segments and symbols.

Release version

As last voice in the main menu, starting with the “r” letter, are shown the release data of the device that can be scrolled pressing the key .
Please note these values and communicate them to Elesa in case of support needed.

Password

It is possible to avoid the unwanted access to the device menu by choosing “on“ in the PASS voice of the menu.
In this case to enter the menu is asked to insert the correct password: 22011 (see cap. 8).

Battery replacement

The internal lithium CR2450 – 3.0 V battery ensures up to 5 years battery life (3 years for RF version).

The symbol is shown on the display when the battery replacement is required.
The replacement is made by simply unscrewing the two TORX T6 screws and removing the front cover, without disassembly the indicator from the control shaft and keeping unchanged all the configuration parameters.
