SICK Ranger3

11 Troubleshooting
11.1 Triggering the camera too fast
When you use Ranger3 with an external line trigger source it is possible to trigger the
camera too fast. This means that a new trigger arrives before the sensor can acquire
new data. When configuring Ranger3 , the max value of the AcquistionLineRate parameter
indicates how fast the camera can be triggered. If the trigger rate exceeds this, triggers
will be missed.
When a single trigger is missed, the triggering of the profile is delayed until the sensor
is ready. If several triggers are missed before the sensor is ready, only one trigger will
be used, and the others will be discarded. The camera will signal an error of class
WARNING with information about the missed trigger event. This is also followed later by
INFO messages giving details of the error. The details can be logged for further error
analysis by technical support but contain no further user information.
If triggers are missed when it is not expected there might be noise on the trigger inputs.
11.2 Encoder line trigger setup tips
In the DigitalIOControl section the LineStatus parameter can be used to pull the status of
the digital inputs for the encoder and the frame trigger. This makes it possible to see if
the inputs are switching as expected.
In the EncoderControl section the EncoderValue parameter can be used to see how the
encoder input signals are counted by the camera. The EncoderReset command will reset
the counter to 0.
11.3 Network card settings
For problems related to the network card settings, see "Recommended network card
settings", page 110.
11.4 Rescue mode
If the State LED on the device turns red, it means that the device has entered rescue
mode and does not allow any data acquisition. There are two possible reasons:
•
The device has discovered a problem with the installed application firmware.
•
The device is overheated.
In Ranger3 Studio, select Save last crash log from the Device menu to export a log file with
details about the error that put the device into rescue mode.
To exit rescue mode, try one of the following options:
•
Disconnect and then re-connect the power to the device.
•
In the Parameter editor, select the DeviceControl category and click DeviceReset. The
button is only visible if the visibility is set to Guru.
•
Upload new valid firmware, see "Updating firmware", page 74.
•
If the device enters rescue mode at multiple occasions and the reason is
unknown, please contact the SICK support.
11.5 Repairs
Repair work on the device may only be performed by qualified and authorized personnel
from SICK AG. Interruptions or modifications to the device by the customer will invalid‐
ate any warranty claims against SICK AG.
