If the pressure drops below the set threshold, the relay is activated (normally open
contact closed). If the pressure than rises above the set threshold with a hysteresis
of 10%, the relay is deactivated again (normally open contact open).

If the gauge is operated in its overrange or underrange, the corresponding bit and
additionally the bit "Reading Invalid" is set.
If an error occurs, the bit "Reading Invalid" as well as the corresponding error bits
in Device Block (ID 26, 27, 28 Device Block) are set.
