Switching outputs
Switching behav‐
ior
PNP switching against supply voltage UV
OUT 1 ... OUT 3:
Resting level: High (no field breach), working level: Low (field breach)
Response time: 134 ms ... 30 s (configurable via SOPAS ET ), holding
time: 0 ms ... 10 s (configurable via SOPAS ET)
OUT 4:
Resting level: High (device ready),
working level: Low (error), low pulse (15 Hz, index, corresponds to mea‐
surement at 90°)

Longer connecting cables at the switching outputs of the device should be avoided due
to the resulting fall in voltage. This is calculated as follows:
Δ
U = (2 x length x current) : (conductance value x cross-section)

Field 1: inner, field 2: center, field 3: outer
Active: in working position; deactivated: in resting position
Output level: The level of the switching outputs OUT 1 ... OUT 3 is active low (in resting
position: high, in working position: low (field infringed)).
All fields of a field set are also deemed to be infringed during switching on, booting, in
the event of an error, and when the device is switched off.
The OUT 4 switching output works with the following levels:
