Calibrating
Prerequisites
Level sensor is installed, fastened mechanically and connected
electrically (observe color coding of sensor cable)
Tank empty (empty calibration: most sensitive setting, material irrelevant)
Operating voltage is applied (LED Operating voltage (1) lit).
Sensor Break
1. Turn potentiometer A (3) 20 revolutions to the left.
2. Turn potentiometer P3 (2) to the right until the green LED empty (5) is off
and the red LED full (6) flashes.
NOTE: Skip step 2. if the LED state is already known.
3. Turn potentiometer P3 to the left to the switching point (green LED empty
on, red LED full off).
4. From the switching point, turn one to two revolutions more to the left.
NOTE: The closer the setting is to the switching point, the more precise is
the measurement. When the potentiometer P3 is turned all the way to the left,
sensor break monitoring is deactivated.
5. Perform function test: Disconnect sensor cable; sensor break monitoring
is triggered (red LED full flashes).
Limit Switching Points
6. Turn potentiometer A to the right to the switching point (green LED empty
off, red LED full on).
7. Turn back from switching point until the green LED empty is on.
