• If the level is below SP1, the output is switched.
If the level is above SP1 or if there is a wire break, output 1 switches off (alarm
message "overflow / wire break“).
• If the level reaches SP2, output 2 switches (upper preset value reached; finish
refilling).
• If the level is below SP3, output 3 switches (below lower preset value; start
refilling).
• If the level is above SP4, the output is switched. If the level is below SP4 or if
there is a wire break, output 4 switches off (alarm message "below min. value /
wire break“).
16.2 Pumping station
Empty the tank / overflow prevention with 3 switching outputs.
Output OUT4 can be used for temperature monitoring:
[SEL3] = [LEVL], [SEL4] = [TEMP]
Replaces 3 float switches and 1 temperature switch
Configuration of the switching outputs 1...3
SP1
Maximum value exceeded
→ alarm.
ou1
Hysteresis function, normally closed (Hnc).
SP2
Upper value exceeded
→
submersible pump ON.
ou2
Hysteresis function, normally open (Hno).
SP3
Below the lower value
→ submersible pump OFF.
ou3
Hysteresis function, normally closed (Hnc).
rP1...3 Each slightly below SPx to suppress wave movements.
