Rotary switches:
The function on/off delay is not part of the safety function and must be set to 0 s.

Hz
Example 1: 321 mHz: M1 = 3, M2 = 2, M1 = 1; E = -3
Example 2: 50.6 kHz: M1 = 5, M2 = 0, M1 = 6; E = 2
Hysteresis: H = {0.5, 1.0, 2.5, 5.0, 7.5, 10.0, 12.5, 15.0, 17.5, 20.0} [%]

Description
2-point
In 2-point mode a lower switch point BotOff and an upper switch point TopOn can be defined in
the permissible measuring range.
The switch points must fulfill the following condition:
BotOff ≤ TopOn
The hysteresis can be 0.
The switching behavior depends on parameter “inversion”.
The following figure shows the switching behavior when inversion is deactivated:
Fig. 4: 2-point mode
4-point
In 4-point mode a window with a lower and upper hysteresis is formed.
The switch points must fulfill the following condition:
BotOff ≤ BotOn < TopOn ≤ TopOff
The hysteresis can be 0.
The switching behavior depends on parameter “inversion”.
The following figure shows the switching behavior when inversion is deactivated:
