level is reached, this is signalled by the LED OUT1 going out and output 1

switching off�

15.2 Pumping station / empty the tank with overflow protection

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 protection
SP2

Maximum value exceeded → alarm

rP2

Slightly below SP2 (to suppress wave movements)

OU2

Hysteresis function, normally closed (Hnc)

XX�X = display value

A = emptying

B = overflow protection

•

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�
