Diagnostics
Display Possible cause Rectification of the error
The S300 is receiving
no measured values
within a range of at
least 90° (measuring
range maximum
29.9 m), it thus is not
detecting any ob-
stacles such as e.g.
building walls.
For the correct function of the safety laser
scanner, always ensure that measured
values are received within a range of 90°;
this range can be moved as required within
the scan range.
Device is dazzled Check whether the S300 is being dazzled by
an external light source, e.g. headlight,
infrared light sources, stroboscopic light,
sun etc.
If necessary, re-mount the device.
Temperature error. The
operating temperature
of the S300 has excee-
ded the permissible
range.
Check whether the S300 is operated as per
the permissible ambient conditions.
Invalid configuration of
the EDM
Verify that the machine-side EDM is
connected correctly.
The addresses of both
the host device and
the guest device may
have been set to
guest.
A device connected via
EFI or the connection
to the device is
defective or disrupted.
Disconnect the connection to the host
device (see section 6.1.1 on page 82).
Check the connected device and the
connection to this device.
Undervoltage of the
supply voltage
Check the power supply or the connecting
cables.
There is a short-circuit
between the input for
the control switch for
restart or reset and
another input or
output.
Check the wiring for cross-circuits.
Input signal for an
undefined monitoring
case
Incorrect sequence on
switching the
monitoring cases
Check the path of the vehicle.
Or:
Check the operating process of the
monitored machine or system.
If necessary, check the configuration of the
monitoring cases with the aid of the CDS.
Incorrect operation of
the control inputs
Check the operation of the digital control
inputs.
