Window function
Technical data
Page 26
The window function enables the
monitoring of a defined accepta-
ble range. When the level varies
between the switch-on point
(SPx) and the switch-off point
(rPx), the output is switched (win-
dow function/NO) or not swit-
ched (window function/NC).
The width of the window can be
set by means of the difference
between SPx and rPx. SPx =
upper value, rPx = lower value.
