Example for the practical usage of the limit outputs
Task:
The limit output No.1 should control a heater, that switches
ON when the temperature goes lower than 70 ºC, and
switches OFF when it goes higher than 90 ºC.
The limit output No.2 should control a buzzer. The buzzer
should be signalling continuously as long as a manual
acknowledgement takes place, in those cases when the
temperature goes, at any time, lower than 50 ºC, or when it
goes higher than 95 ºC
The settings of the limit outputs are as follows:
