Diagnostics
Display Possible cause Rectification of the error
 Waiting for valid input
signals
 The indication extinguishes automatically if
an input signal is present that corresponds
to the configured evaluation type (1-of-n or
complementary).
If the display  does not go off:
 Check the wiring.
 Check the control signals for correct
switching behavior.
 Check, if velocity ranges are used for moni-
toring case switching, whether the EFI status
information Speed valid is transferred (see
Tab. 37 on page 131).
 Check the system configuration with the aid
of the CDS. Transfer the corrected configu-
ration to the S300 again.
 Waiting for
configuration or
configuration not
completed
 The display goes off automatically once the
configuration has been successfully trans-
ferred.
If the display  does not go off:
 Check the system configuration with the aid
of the CDS. Transfer the corrected configu-
ration to the S300 again.
 Check whether the configuration saved in
the system plug is compatible with the S300
(see 10.3 on page 106).
 Waiting for restart of
the device
 Switch off the voltage supply for the S300
for at least 2 seconds and then switch it
back on.
 or

Error of the external
device monitoring
(EDM)
 Check whether the contactors are working
correctly or if they are wired incorrectly and
rectify any error.
 If  is displayed: also switch off the voltage
supply for the S300 for at least 2 seconds
and switch it back on.
 Error in the control
switch for restart or
reset
 Check the functionality of the control switch.
The button may be defective or permanently
operated.
 Check the wiring of the control switch for
short-circuit to 24 V.
   Velocity tolerance
exceeded: The diffe-
rence between the
velocities measured by
the incremental enco-
ders is too large.
 Check the incremental encoders.
 Check the configuration of the incremental
encoder inputs with the aid of the CDS.
