Abstract (en)
[origin: EP2226515A2] The limit signal indicator (1) has position sensor (15), Namur-sensors (33,35,65,63) and microprocessor (41). At least any of Namur-sensors is connected to switch amplifier for signal transmission so that in case of malfunctioning of signal transmission, the switch amplifier generates emergency signal above maximum limit value or below lower limit value. The microprocessor executes an emergency procedure according to which emergency signal is generated upon detecting specific operational malfunctioning of at least any of limit signal indicator, positioning valve (11) and positioning drive (5). An independent claim is included for an operating method of limit signal indicator.
