QUESTION:

How can short-term errors / releases of safety components be recognized? The system remains at a standstill but it is not known which component has released.

ANSWER:

During the troubleshooting of sporadic releases, functions “diagnostics hold” respectively “local acknowledgment” should be activated. Those are the general methods to localize the cause.

With this information, the corresponding safety components can be examined more closely and therefore necessary measures regarding mechanics, EMV or system construction can be initiated.

If necessary, the analyzer AS-Interface 3RK1904-3AB01 could be used. The AS-i Analyzer is used for testing AS-Interface networks. Troubleshooting is made systematic and permanent monitoring facilitated.
This device is able to detect errors during the installation such as loose contacts or EMV problems.
The easy-to-use software makes it possible to check the quality of whole systems even without detailed technical knowledge about AS-Interface. The analyzer furthermore makes possible documentation of commissioning and services by the simple generation of test reports for the recordings made.
Detailed diagnostics are made possible for advanced AS-Interface users by means of trigger functions.
