Dynamization pulse width incorrect

Hva betyr F3135 ?

This non-fatal safety error indicates that the pulse width of dynamization signals, used for testing safety inputs/outputs, has been detected as incorrect on the IndraDrive MPx02. An incorrect pulse width can prevent proper fault detection or lead to nuisance trips, compromising the integrity of the safety system.

• Incorrect parameterization of the dynamization pulse width (e.g., S-0-0083, S-0-0084).
• Signal distortion due to long cables, improper shielding, or excessive electrical noise.
• Faulty internal hardware generating or monitoring the dynamization pulses.
• External safety device drawing too much current or presenting an unexpected load during dynamization.

1. 1

   Check and correct the configured dynamization pulse width parameters (e.g., S-0-0083, S-0-0084) in the IndraDrive MPx02 to meet the specifications of the connected safety devices.

2. 2

   Inspect the wiring of safety inputs/outputs for proper shielding, correct cable length, and secure connections.

3. 3

   Verify that the connected external safety devices are compatible with the dynamization pulses generated by the IndraDrive MPx02.

4. 4

   Measure the actual dynamization pulse width at the input/output terminals using an oscilloscope to identify discrepancies.

5. 5

   Eliminate potential sources of electromagnetic interference that could be distorting the pulse signals.
