7.14.4.3 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.
Pin Designation Description
1 F1 Detector contact 1
2 F2 Detector contact 2
7.14.5 Connecting the safety module FN2009
7.14.5.1 Connector strip for supply
Pin Designation Description
1 L1+ Supply input 1 (+DC 24 V)
2 M1 Supply input 1 (DC 0 V)
3 M2 Redundant supply input 2 (DC 0 V), optional
4 L2+ Redundant supply input 2 (+DC 24 V), optional
The L1+/M1 and L2+/M2 connections are designed for redundant supply and are
not plated-through. Use of the redundant L2+/M2 supply inputs is optional and not
necessary for EN-54 compatibility.
7.14.5.2 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.
Pin Designation Description
1 F1 Detector contact 1
2 F2 Detector contact 2
