6.2 Error state indicators
The SLE 3 constantly carries out internal tests and tests on the connected sensors and
monitors the plausibility of external and internal switch states. If the SLE 3 detects a
problem, an error or error state is set and lifting or lifting and lowering is blocked.
The possible errors and their indication are described in the following table and must be
corrected before further operation is possible.
III II I err pwr Cause Consquence Correction
Sensor error:
Broken cable, short
circuit
Lifting blocked •
Check load sensor connection: screw terminals for
tightness (-S, -IN, +IN, +S), correct wire assignment
per circuit diagram
•
Measure sensor supply voltage (+S / -S): set point
value 9.5…10.5 V
•
Measure the output voltage of the connected sensor
(-IN / -S, +IN / -S): value approx. 5 V
•
Measure the sensor values at the disconnected
sensor: set point values:
between wires RED / BLACK: 350 … 400

between wires BROWN / ORANGE: 346 … 356

Overload Lifting blocked •
Put down the overload and reduce the load
•
Correct the cut-off threshold (during commissioning,
with test load)
Overheating 1 or
thermistor error
Lifting and
lowering
blocked
•
Let the motor cool down
→
the error state is acknowl-
edged automatically
•
Check the wiring of the thermistor
•
Check the thermistor resistance with the motor cold:
– If the measured resistance is 150...750

, the
thermistor input is defective and the device must
be replaced.
– If the resistance is greater or smaller, the thermis-
tor is defective and the motor must be replaced.
Offset correction error Lifting blocked •
Existing device: check the load sensor
→
see above
•
New device: carry out offset calibration
•
If the error occurs in testing bay mode, then check the
load sensor wiring
Lifting and lowering
actuated at the same
time
Lifting and
lowering
blocked
•
Error in the wiring.
•
Check the control cables to the terminals 3, 4 and 5 at
the SLE
Internal error Lifting and
lowering
blocked
•
Check the voltage at terminal 6
•
Restart the device
•
If the error occurs again after a restart, the device
must be replaced
No power supply availa-
ble, device fuse defective Device does
not work •
Check the power supply of the device
