Especially for silo-
tanks a „tank overflow protection“ can be set in three different
ways:
Via level switch
A
“tank full”
Precondition: installed “level switch tank full”
Set parameter [P42] to 1 or 2, depending on the switch used
Assign to one of the digital inputs [A21..A33] the function 18 “level sensor tank full”
Via level electrode
A
(connected to level 2 of the control)
Precondition: installed level electrode
Set parameter [P42] to 4.
Via litre-recording by pressure sensor
B
Precondition: installed analogue pressure sensor “filling level”
Set parameter [P42] to 3
Enter the maximum filling quantity of the silo-tank in hectolitres ((= 100 litres) in
parameter [P43]
Set level switch as described in section 10.5
Fault display:
When the upper filling level is achieved fault [F51] “tank overflow
protection” is triggered.
