1. General Introduction
The functions of the switch outputs (2 relay outputs and 1 potential free transistor output) are easily adjustable [trip value display (min/max alarm), serially switched output, pulse divider output, error signal output]. The device is easily configured by the use of keypad or with the PACTware configuration software. A fault is signalized by LEDs acc. to NAMUR NE44 and a separate collective error message output. For additional information, refer to the manual and www.pepperl-fuchs.com.
