Meaning
Short circuit of the lines
between the electronic module
and sensor
Line to the actuator interrupted.
No sensor connected.
Sensor does not respond.
Maintenance requirement
(signal quality < 130 %, excess
gain), sensor-dependent
Communication error between
the electronic module and
sensor
Parameter assignment error.
Inserted module does not
match the one configured.
Teach-in error (a new value
could not be
determined/obtained)
Inserted sensor does not match
configured sensor.
Excess gain lower limit violated
(signal quality < 110 %) or
sensor error, sensor-dependent
Teach-in process running.
Alignment tool is active.
