5.37.4.3 Connector strip for detector contact
The detector contact is a potential-free relay contact which can be used to report
error states by interrupting contact.
The following errors can be signaled by the detector contact:
● Loss of a link on a monitored port
● Failure of a redundant source of voltage
● Incompatible C-plug inserted
The detector contact remains activated until the error is rectified or until the current
status is adopted by the button as the new nominal status.
The detector contact is always activated (opened) by switching off the FN2008-A1.

5.37.5.2 Connector strip for detector contact
The detector contact is a potential-free relay contact which can be used to report
error states by interrupting contact.
The following errors can be signaled by the detector contact:
● Error in voltage supply
● Internal error
The detector contact remains activated until the error is rectified.
The detector contact is always activated (opened) by switching off the FN2009-A1.
