11 Error Detection
In order to ensure a maximum of operational safety and reliability, the Safety Monitors
are equipped with several and profound monitoring-functions. This monitoring allows
immediate recognition and messaging of possible failures and malfunctions.
In case of errors:
• The relay contact switches to its open (safety) condition
(interruption of the safety circuit)
• The analog output sets to 0 mA
(which is out of the regular operating range of 4 … 20 mA)
•
All control outputs are set to LOW.
No more inversion between OUT and /OUT
(Attention in case of homogenous configuration!)
• Encoder splitter output does not provide any incremental signals (tri-
state with pull-down termination)
The following types of error recognition are distinguished:
•
Initialization Test Error
• Runtime Test Error
Both error types are described in detail on the following pages.
