input has been made for 20 minutes.
Minimum / Maximum Limit Switch

Input Alarm relay function
0 Max. alarm switch
1 Min. alarm switch
Here you can define if the alarm relay should switch as max. or
min. alarm.
If set correctly, the relay drops out and the contact between ter-
minal 12a and 12c is open if an alarm is triggered.
Max. alarm switch:
If an alarm is to be triggered in case of overfilling.
Min. alarm switch:
If an alarm is to be triggered in case of underfilling.
Switching threshold (%)
Switching threshold in percent
(Only in the professional mode)
Input Limit value Code
-1 Automatic C
>0 Fixed value in % C
If the switching threshold is exceeded, the device indicates an
alarm.
If the switching threshold is set to automatic (factory setting), it is
already set up optimally. If you wish to set another switching
threshold, you can enter a fixed value in % level.
You can enter the switching threshold either as a percentage value
in this code or in code 18. Every entry in this code automatically
calculates the new count rate in code 18. Vice versa: If you enter a
fixed value (count rate) in code 18, then the percentage value in
code 17 is calculated new.
