Two point mode
The switching information changes when the measurement value passes the threshold defined in setpoint
SP1. This change occurs only with rising measurement values. The switching information also changes when
the measurement value passes the threshold defined in setpoint SP2. This change occurs only with falling
measurement values. Hysteresis is not considered in this case.

Window mode
The switching information changes, when the measurement value passes the thresholds defined in setpoint
SP1 and setpoint SP2, with rising or falling measurement values, taking into consideration the hysteresis.

2.4.1.3. Hysteresis Settings
The hysteresis can be set automatically or manually for SSC1 and manually only for SSC2. The hysteresis is
set as a percentage of the set value chosen for SP1 and SP2.
Note: When trimmer is selected, the default hysteresis is Automatic.
Automatic hysteresis:
Automatic hysteresis will guarantee stable operation for most application.
Hysteresis is calculated with reference to SP1/SP2 and the actual values can be read via parameter "SSC1
Auto hysteresis", typically 25% of the set value for SP1 and SP2.
Manual hysteresis:
When manual hysteresis is selected, the hysteresis can be changed between 5 ... 99%
For application that require a hysteresis other than the automatic, the hysteresis can be configured manually.
This feature makes the sensor more versatile.
Note: Special attention to the application must be considered when choosing a hysteresis lower than the
automatic hysteresis.
