Troubleshooting
Table 7: Possible error displays via the LEDs
LED indicator/fault pat‐
tern / Fault pattern
Cause
Measures
Green LED does not light
up
No voltage or voltage below the
limit values
Check the power supply, check
all electrical connections
(cables and plug connections)
LED 1 + LED 3: Quick flash‐
ing
During a teach attempt outside
the detection range, no end
point is applied
Bring pistons into the detection
range of the sensor
If no or only one end point is
found during
Dynamic Teach
, no
end points are applied
Adjust the position so that two
end points are found
Sensor position is impre‐
cise
Mounting position unfavorable
Position sensor head as recom‐
mended in the operating
instructions and run voltage
reset
Sensor does not find end
positions in Dynamic Pilot /
does not switch
Traversing speed of the object is
insufficient
Increase traversing speed of the
piston or deactivate Dynamic
Pilot and manually teach in end
positions
End positions are lost
Sensor was not yet completely
taught in to drive
Perform several strokes (> 5)
and reset end positions
