Hello,I was attempting to calibrate the DLC3 digital load cell interface, and I believe I may have pressed the wrong button during the process. Since then, the screen has started blinking continuously and does not stop unless I disconnect the Profibus cable leading to the PLC. However, once I reconnect the Profibus cable, the blinking resumes.
Could you please assist me in resolving this issue?

To resolve the continuous blinking issue on the Logic DLC3 digital load cell interface after incorrect calibration, perform the following steps:
1. Enter the calibration menu. 2. Use one of the supported calibration methods: - Calibration with sample weights. - Calibration with a load cell simulator. - Automatic calibration using known load cell parameters. - Correction of the zero value. - Correction of the full scale value. 3. Follow the menu instructions to correctly calibrate the instrument.
Proper calibration should stop the continuous blinking caused by prior incorrect calibration.

The connection to the load cells must be done with high quality shielded cable. The cable CAB-TS6 Logic model is recommended for all industrial applications including areas with risk of explosion. In applications with more load cells (platforms, tanks, silos, etc.), It is recommended the use of junction boxes that minimize differences in impedance or compensation on the signal branches.

Do you have a question about the DLC NET Series and is the answer not in the manual?
Questions and answers
Hello,I was attempting to calibrate the DLC3 digital load cell interface, and I believe I may have pressed the wrong button during the process. Since then, the screen has started blinking continuously and does not stop unless I disconnect the Profibus cable leading to the PLC. However, once I reconnect the Profibus cable, the blinking resumes. Could you please assist me in resolving this issue?
To resolve the continuous blinking issue on the Logic DLC3 digital load cell interface after incorrect calibration, perform the following steps:
1. Enter the calibration menu.
2. Use one of the supported calibration methods:
- Calibration with sample weights.
- Calibration with a load cell simulator.
- Automatic calibration using known load cell parameters.
- Correction of the zero value.
- Correction of the full scale value.
3. Follow the menu instructions to correctly calibrate the instrument.
Proper calibration should stop the continuous blinking caused by prior incorrect calibration.
