Set-up/Operation

Check the safe functioning of the unit. To do so, bring about a sensor
response by taking suitable measures.
Display by LEDs:
LED green
LEDs green +
yellow
LED yellow
LED red
The red LED becomes active for a short time during the change bet-
ween "medium not present" and "medium present" (flashes at 1Hz)
if the medium is close to reaching the switching threshold. This can
occur in particular if the level changes very slowly and is no error mes-
sage meaning a fault in the unit.
The operation of the level switch is maintenance-free. For a correct
function ensure:
• The sensing face and the open space should be kept free of depo-
sits and foreign bodies, particularly for mounting with the sensing
face showing upwards.
• Flashes slowly (1Hz): adjustment mode empty state or
NO/NC mode (output configured as normally open)
• Flashes quickly (2Hz): adjustment mode full state
• OFF: unit in the operating mode
• flash alternately (1Hz): NO/NC mode
(output configured as normally closed)
• OFF: switching output disabled
• ON: switching output enabled
• flashes quickly (8Hz): adjustment error, internal fault
• flashes slowly (1Hz): close to reaching the switching thres-
hold
