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 °C, and
switches OFF when it goes higher than 90 °C.
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 °C, or when it
goes higher than 95 °C
The settings of the limit outputs are as follows:

 operating mode=

(Switches ON, when the
temperature is lower than the low limit) 

 Low limit =

°C

 Hysteresis of the low limit =

°C 

High limit =

°C (it’s value is indifferent)

Hysteresis of the high limit =

°C (it’s value is
indifferent)

 Alarm mode =




 Operating mode=

(Switches ON, when the
temperature does not fall between the limits.) 
