Min Limit Value; Min Signal (Pressure); Min Signal (Level) - Siemens TXP-CLC Manual

MIN limit value

For a MIN limit value the switching point is obtained by changing the measured
variable in relation to a minimum value, i.e. < MIN. For the MIN limit value the
< MIN signal is derived from the NCC of the switching device. Figure 8 and 9
show examples of < MIN signals for pressure and level. The < MIN signals are
assigned serial numbers of XG52 and NOT MIN signals are assigned serial
numbers of XG02.
