Frequently Asked Questions (FAQ)

Eltra's products are developed and manufactured following all the required procedure to ensure the top quality of products, and singularly tested in our Headquarters before being delivered to the Client.  

Most of the malfunctioning of the device are due to an incorrect installation. We strongly recommend to read carefully data-sheet and all the technical documentation before proceeding with the installation of the encoder and to ensure that it's done only by qualified staff.

Please find below some of the most frequent queries that we receive and the procedure to follow in order to identify and/or solve the problem.

 

There is no output
  • Verify that all wiring is properly connected to the control system and the correct power supply provided (please read carefully data sheet and installation instructions).
  • Verify that the encoder shaft is moving; if there’s no motion, the encoder doesn’t produce change of status.
  • Verify the proper connection of the device to the ground. If necessary, provide an additional external connection.
  • Verify that the products output (or interface) is compatible with the control system.
  • Verify that the cable doesn’t exceed the length: the signal power may be reduced by an excessive extension of the connection.
  • If there’s another device available, make a test with the other one.
  • If possible, test the output signals of the products with an oscilloscope.
The product is not counting correctly
  • Verify that the control system is compatible with the output signals/interface of the product.
  • Verify potential interference/electrical noise between the product and the control system.
  • Verify that the product is correctly fixed to the application.
  • When using adapters for the shaft (elastic couplings) or for the product (flanges), verify that they are correctly fixed (as indicated in the installation manual); if you are using adapters of other brands, make sure they are fully compatible with the product.
The product presents signal noise
  • Verify that power and signal cables are far from power lines.
  • Verify that power lines have that proper filters and cable shielding.
  • Verify that shielded and twisted cables are used and that they are connected properly to earth ground.
  • In case of notable cable length, the use of differential signals (line driver) is suggested in order to reduce “common noises”.
Only one channel is working (incremental encoders)
  • Verify installation and wiring scheme for a correct connection
  • Verify that the control system is compatible with the encoder.
The encoder is counting in only one direction (incremental encoders)
  • Verify the presence and correct functioning of both A and B channels.
  • Verify that the control system is programmed to detect bidirectional signals.
  • We suggest to test with an oscilloscope the presence of channel A and B and that they present the proper phase displacement.
Input index is not working properly
  • Verify the wiring.
  • Verify that the control system is programmed to detect the input signal, also at high rotation speed.
Other possible problems
  • Verify not to exceed the maximum radial and axial shaft loads values, as indicated in the data-sheet.
  • If bearings seem rough or noisy, verify the installation and alignment.
  • Verify the encoder’s protection sealing when operating in presence of liquids and dust.
  • Verify minimum and maximum values of operating temperature in extremely cold or hot working environments.

Our Technical Support Team is at disposal for assisting and helping to solve doubts and inquiries regarding the correct installation of Eltra's products.

Correspondence between EL and ER series

Our Research & Development Team is continuously searching for new solutions and improvements to the electronics and mechanical performance of our transducers.

As a result of several technical modifications and implementations, the optical incremental "EL" encoder series has been updated by the new "ER" series.

The "ER" encoder series are interchangeable with the previous "EL", having the same design though with interesting application benefits

•  Increase of temperature range
•  Increase of operating frequency

 Please find below a comparative scheme between "EL" and "ER" series: 

  EL 30 ER 30

Meaning of .V2, .L, .T suffixes

Our Research & Development Team is continuously searching for new solutions and improvements to the electronics and mechanical performance of our transducers.

As a result of several technical modifications and implementations, the following suffix had been identified:

- .V2 (only for EMB series): the EMB updated series - whose description ends with .2V - is fully intercheangeable - both mechanical and electronically - with the previous one.

EMB .1V .2V
Max Frequency [KHz] 100 200
Working Temperatureo [°C] 0/+50 -20/+85

- .L: only for internal use, it doesn't represent any change from Customer perspective

- .T: it represents an extended temperature range compared to the standard version (10/+70 °C, -10/+100°C only for some EL/EF49 resolutions.)

 

End Of Life | Product Change Notification

As part of our on-going product lifecycle management process, we have identified products that will be transitioned to an "End-of-Life" status or a Product Change Notification.  Products targeted for end-of-life may be available for a last time buy option (LTB) prior to being made obsolete, however quantities are limited and special requirements may apply.

Q. What are the last time buy conditions and dates?
A. All purchase orders are non-cancelable and non-returnable. If a LTB is offered, the following dates apply:

  • Date of last order acceptance: last date of order acceptance of the order, or until stock runs out.
  • Date for last shipments: latest delivery date

Q. Is there a replacement product?
A. If there is any product indicated as replacement, please check carefully the specs and take note that the recommended parts may or may not be drop-in replacement; they may be the closest replacement available.

Please don't hesitate to contact us (Tel: +39 0444 436489 | support.eltra@broadcom.com) if you have any questions or concerns about EOL and PCNs.
