Level control with one fill factor
Deplete
Connect the level control completely and bring the sensor in position. Fill the receptacle in
such a way that the sensor is a little immersed (maximum fill factor).
Adjust front switch to: one level, filling, high sensitivity. Rotate potentiometer clockwise to the
stop. Relay (R) must not be active. Now turn the potentiometer slowly counter clockwise to
the left. If the left stop of the potentiometer is reached, turn it again clockwise until the right
stop is reached. Adjust front switch to “low sensitivity” and turn the potentiometer again
counter clockwise to the left. If the relay now switches automatically, the impedance of the
liquid has fallen below. Now you have to turn back the potentiometer half turn. If you reach
the right stop position before, switch back to „high sensitivity“ and execute the half turn to the
right there.
Set front switch to “emptying”. Now the relay should become active. The level control is now
ready.
Level control with two fill factors
Fill
Connect the level control completely and bring the sensors in position. Fill the receptacle in
such a way that the sensor S2 is a little immersed (maximum fill factor).
Adjust front switch to: two level, filling, high sensitivity. Rotate potentiometer clockwise to the
stop. Relay (R) must not be active. Now turn the potentiometer slowly counter clockwise to
the left. If the left stop of the potentiometer is reached, turn it again clockwise until the right
stop is reached. Adjust front switch to “low sensitivity” and turn the potentiometer again
counter clockwise to the left. If the relay now switches automatically, the impedance of the
liquid has fallen below. Now you have to turn back the potentiometer half turn. If you reach
the right stop position before, switch back to „high sensitivity“ and execute the half turn to the
right there. The level control is now ready.
