Both switches can be inverted, which means you can decide whether a switch bit is
issued as "low" or "high" from a specific force. In addition, a hysteresis can be assigned
to both limit value switches so that there is another switching process if the force is
smaller (or greater) than the switching point.

Setting the limit value switch
u
In the "Config Mode" field, you must first select whether
- The limit value switch is inactive (deactivated)
- A single pulsating force (and hysteresis) is set (single point)
- A switching point and a release position should be specified (the difference is then
the hysteresis)
- Range monitoring is required that will issue a signal if the value is below or above
the force range (window mode)
The following applies to all of the operating modes:
S
Increasing compressive forces are rising forces
S
Decreasing tensile forces are rising forces
S
Decreasing compressive forces are falling forces
S
Increasing tensile forces are falling forces
