The level sensor system now is in the adjusting mode with the green
LED (4) "Cal/Err" flashing. The current consumption of the level sensor
is 12 mA. Without pressing the key again, the level sensor remains in the
adjusting mode for 20 seconds before changing back to the measuring
mode without modifying the adjustment.
To fix the 4 mA point within this period
■ move the float to the desired position,
■ and press down key "4 mA" (2) for a short period of time
(0.1 ... 2 seconds)
The LED display will disappear for 5 seconds, with the current consump-
tion being 4 mA, and thereafter again 12 mA. The level sensor will
remain in the adjusting mode for another 15 seconds before changing
back to the gauging mode.
