Error- And Warning Messages - Norgren Herion 33D Serie Handbuch

2.2 Hysteresis-MODE:
During the course of the set point setting either the switch-on flank (n.o status) or the switch-off flank (n.c status) will
blink, depending on the operating mode. When setting the hysteresis mode consequently the hysteresis mode will
blink. Depending on the set polarity (n.c. / n.o. see setup) the hysteresis diagram will appear on the display with the
Picture 2: Switching OUT 1n.o., switching OUT 2 n.c.
2.3 Window MODE:
This operating mode provides the definition of a switching point and a reset point within a pressure range. In case the
prevailing pressure is within this "window", the switching out will be activated (polarity n.o.) or inactivated (polarity
n.c.)
