Set-Up /Operation - IFM Electronic Efector 150 KNM Operating Instructions Manual

Further errors:
• Electronic fault or sensing zone of the unit damaged
• Internal fault (can only be deleted by power off and then power on
again, hardware reset)

Set-up /Operation

Check the safe functioning of the unit. To do so, bring about a sensor
response by taking suitable measures.
Indication by LEDs and function check output:
LED green
LED yellow
LED red and
function check
output
LED yellow and red
together
The red LED and the function check output are briefly active during the
change between "medium not present" and "medium present". This
can occur in particular if the level changes very slowly and is no error
message 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.
ON = unit is ready for operation
Flashes slowly (1Hz) = adjustment mode empty state
Flashes quickly (2Hz) = adjustment mode full state
OFF = switching output disabled
ON = switching output enabled
Flashes quickly (8Hz) or 8Hz signal of the function check
output = adjustment error, internal fault
ON = close to reaching the switching threshold
Flash quickly (2Hz) simultaneously
= short circuit in the switching output
OFF = locking mode
