16.2 Pumping station
Empty the tank with overflow prevention
Switching output 1: control to empty tank
SP1
upper value exceeded → submersible pump ON
rP1
lower value reached → submersible pump OFF
ou1
hysteresis function, normally open (Hno)
Switching output 2: overflow prevention (for the LK10xx, it is recommended to use the
integrated overflow prevention (parameter [OP])
SP2
maximum value exceeded → alarm
rP2
slightly below SP2 (to suppress wave movements)
ou2
hysteresis function, normally closed (Hnc)
OP
overflow prevention *)
XX.X = display value
A = empty, B = overfill prevention
• If SP1 is exceeded, output 1 switches (submersible pump ON). If the level is
below rP1 again, output 1 switches off (submersible pump OFF).
• If SP2 is exceeded or if there is a wire break, output 2 switches off.
*) It is recommended to use the integrated overflow prevention (parameter [OP]). If SP2 is
set to the maximum value, the response of the overflow prevention (OP) leads to a swit-
ching operation immediately and without delay. In that case, SP2 functions as a directly
acting overflow switch point.
