For devices calibrated under rising pressure the following applies:
If the maximum value of the setting range is set as the switching point, the reset point is lower by
the value of the average switching differential. (e.g. DWR6: setting range 0.5-6 bar, switching point
6 bar, reset point 5.8 bar) If the minimum value of the setting range is used, then the lowest setting
value is also the reset point. The switching point must be set higher by the value of the average
switching differential (e.g. DWR6: 0.5-6 bar, switching point 0.7 bar, reset point 0.5 bar).
For devices calibrated for falling pressure the following applies:
If the minimum value of the setting range is used, then the lowest setting value is also the switch-
ing point. The reset point must be set higher by the value of the average switching differential
(e.g. DWR6-206: 0.5-6 bar, switching point 0.5 bar, reset point 0.8 bar). If the maximum value of
the setting range is used, then the highest value of the setting range is also the reset point. The
reset point must be set higher by the value of the average switching differential (e.g. DWR6-206:
setting range 0.5-6 bar, reset point 6 bar, switching point 5.7 bar).
The following applies for all devices:
All switching and reset points must be within the limits of the specified setting range given in
the technical data sheet.
