The Low Trip Point is a fixed value:
The value defined in Low Trip Point Limit is compared with the pressure value
referenced by the Source Index parameter.
Calculating the High Trip Point and Low Trip Point → chapter 4.5.2.

High Trip Point Limit: High limit to trigger trip point condition if Input Value
(I 0x900E, SI 0x01) is above this limit.
Percentage of High Trip Source: Percentage of Piezo Sensor Value (I 0x6010,
SI 0x11) in [%].
Low Trip Point Limit: Low limit to trigger trip point condition if Input Value (I 0x900E,
SI 0x01) is below this limit.
High Trip Hysteresis: Hysteresis value for High Trip Point.
