Example: You want to have a temperature alarm-monitoring of a greenhouse. The alarm should start when
the temperature rises above 50°C or falls below 15°C.
Therefore your settings will be 50°C for the maximum alarm-
value “AL.HI“ and 15°C for the mini-
mum alarm-
value “AL.Lo“.
The alarm will be starting after the temperature rises above 50°C and stays above 50°C for the
entered delay time or after it had been falling below 15°C and stays below 15°C for the entered
delay time.
Please note that the alarm-outputs are inverted! This means, that the output will be active when there is no
alarm!
Now you finished configuring the alarm adjustment of your device. Press button 1 to finish the adjustment
and to switch over to display the measuring value.
