It S3 LED yellow: I II transfers digital signals (NAMUR sensors/mechanical Relay output II Switch S2 (Mode of operation channel II) contacts) from a hazardous area to a safe area. LED red: The proximity sensor or switch controls a form C changeover 7 8 9 10 11 12 LB/SC channel II Switch S3 13 14 15 relay contact for the safe area load. The normal output state (LB/SC-monitoring) can be reversed using switches S1 and S2. Switch S3 is used to enable or disable line fault detection of the field circuit. Removable terminals During an error condition, the relays revert to their de- green energized state and the LEDs indicate the fault according to NAMUR NE44. 2 Connection KFA5-SR2-Ex2.W 1+ 7 8 I 10 kΩ 2+ I 9 10 kΩ 3- 400 Ω ≤ R ≤ 2 kΩ 10 4+ 11 II 10 kΩ II 5+ 12 10 kΩ 6- 400 Ω ≤ R ≤ 2 kΩ 14 115 V AC 15 Zone 0, 1, 2 Div. 1, 2 Refer to "General Notes Relating to Pepperl+Fuchs Product Information".
