Default Settings
All DIP switches are in „OFF“ position for delivery.
This is the position used to parameterize the device via PC confi guration software.

! Hysteresis
The digital output (DO) signals error messages and can be confi gured as follows: 24 V→ 0 V/0 V → 24 V.
In order to increase the switching current of the DO, the latter may be expanded by a relay. Thanks to the contour uniformity of Series 857, for example, a 857-304 Relay can be
snapped in next to it. This output can be quickly and easily expanded to a switching current of 6A by simply using an adjacent jumper (859-402).
