Max Limit Value - Siemens TXP-CLC Manual

MAX limit value

For a MAX limit value the switching point is obtained by changing the measured
variable in relation to a maximum value, i.e. > MAX. For the MAX limit value the
> MAX signal is derived from the NOC of the switching device. Figures 10 and
11 show examples of > MAX signals for pressure and level. The > MAX signals
are assigned serial numbers of XG01 and NOT MAX signals are assigned serial
numbers of XG51.
