It S3 I II transfers digital signals (NAMUR sensors/mechanical Switch S2 contacts) from a hazardous area to a safe area. (no functions) The proximity sensor or switch controls a form C changeover 7 8 9 10 11 12 Switch S3 13 14 15 relay contact for the safe area load. The barrier output (LB/SC-monitoring) changes state when the input signal changes state. The normal output state can be reversed using switch S1. Removable terminals Switch S3 is used to enable or disable line fault detection of green the field circuit. During an error condition, the relay reverts to its de-energized state and the LEDs indicate the fault according to NAMUR NE44. 2 Connection KFA5-SR2-Ex1.W 1+ 7 8 10 k 2+ 9 10 k 3- 400 R 2 k 14 115 V AC 15 Zone 0, 1, 2 Div. 1, 2 Refer toGeneral Notes Relating to Pepperl+Fuchs Product Informatio.
