If the actual fluid level exceeds the upper limit of the unit's nominal
range, it can no longer be measured and the display starts to flash.
The values of the switching outputs and analogue outputs are
maintained. The measured peak fluid level or the pre-set offset is
shown in the display.
If, after a voltage breakdown, the display shows "..........." (flashing
centre LEDs), it should be checked whether the tank level is too high
or too low.
The analogue output provides 4 mA resp. 0 V depending on the setting
of the analogue input.
If the actual fluid level falls below the lower limit of the unit's nominal
range, it can no longer be measured and the display will start to flash.
The values of the switching outputs and analogue outputs are
maintained. In the display, 0.0 or the set offset appears.
