Display
Possible cause
Remedy
Speed tolerance
exceeded: The differ‐
ence between the
speeds measured by the
incremental encoders is
too large.
b
Check the incremental encoders.
b
Check the configuration of the incremental
encoder inputs using the CDS.
Direction of movement
output by the incremen‐
tal encoders is different
b
Check the wiring of the incremental encoder
inputs, e.g., for incorrect pin assignments.
Maximum frequency at
INC1 input exceeded
b
Check the function of the incremental
encoders.
b
Check the configuration of the incremental
encoder inputs using the CDS.
b
Check whether the maximum allowed speed
of the vehicle is exceeded.
Maximum frequency at
INC2 input exceeded
b
Check the function of the incremental
encoders.
b
Check the configuration of the incremental
encoder inputs using the CDS.
b
Check whether the maximum allowed speed
of the vehicle is exceeded.
Safety laser scanner
faulty
b
Switch off the voltage supply for the device for
at least 2 seconds and then switch it back on.
If the display does not go out:
b
Send the device or system plug to the manu‐
facturer for repair.
Configuration memory in
the system plug defec‐
tive
A second device which
is connected via EFI is in
the fault state.
b
Check the connected device and the connec‐
tion.
Overcurrent at OSSD
connection 1
b
Check the connected switching element (con‐
tactor, relay) and replace if necessary.
b
Check the wiring for short-circuit to 0 V.
Short-circuit to 24 V at
OSSD connection 1
b
Check the wiring for short-circuit to 24 V.
Short-circuit to 0 V at
OSSD connection 1
b
Check the wiring for short-circuit to 0 V.
Overcurrent at OSSD
connection 2
b
Check the connected switching element (con‐
tactor, relay) and replace if necessary.
b
Check the wiring for short-circuit to 0 V.
Short-circuit to 24 V at
OSSD connection 2
b
Check the wiring for short-circuit to 24 V.
Short-circuit to 0 V at
OSSD connection 2
b
Check the wiring for short-circuit to 0 V.
Short-circuit between
OSSD connection 1 and
2
b
Check the wiring and rectify the error.
General OSSD wiring
error
b
Check the complete wiring of the OSSDs.
Device is addressed as
guest
Not an error. The symbol is displayed for approx.
2 seconds when a device that is addressed as a
guest is switched on.
Device is addressed as
host
Not an error. The symbol is displayed for approx.
2 seconds when a device that is addressed as a
host is switched on.
