Example for the practical usage of the limit outputs
There is a 100-litre tank, whose liquid level is indicated by
the instrument DT9000 in 0-100 litres, without decimals.
Task:
The limit output No.1 should control a pump, that switches
ON when the liquid-level goes lower than 70 litres, and
switches OFF when it goes higher than 90 litres.
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
liquid level goes, at any time, lower than 50 litres, or when
it goes higher than 95 litres.
The settings of the limit outputs are as follows:

 operating mode=

(Switches ON, when the
liquid level is lower than the low limit) 

 Low limit =


 Hysteresis of the low limit =



High limit =

(it’s value is indifferent)

Hysteresis of the high limit =

(it’s value is
indifferent)
