Troubleshooting
11.1
Over triggering
When you use Ruler3000 with an external line trigger source it is possible to overtrig
the camera. This means that a new trigger arrives before the sensor can acquire new
data. When configuring Ruler3000, the max value of the
Timed profile rate (Hz)
parameter
indicates how fast the camera can be triggered. If the trig rate exceeds this, an overtrig
occurs.
When a single overtrig occurs, the triggering of the profile is delayed until the sensor
is ready. If several overtrigs occur before the sensor is ready, only the first overtrig will
cause a trig, and the others will be discarded. The camera will signal an error of class
WARNING with information about the over triggering 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 overtrig occurs when it is not expected there might be noise on the trigger inputs.
11.2
Encoder line trigger setup tips
In the
Profile triggering
section the
Encoder value
parameter can be used to see how the
encoder input signals are counted by the camera. The
Encoder reset
button will reset the
counter to 0.
11.3
Network card settings
For problems related to the network card settings,

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
Stream Setup
, open
Camera files
and select
Retrieve from camera
for
All Crash Logs
to
export log files with details about the error that put the device into rescue mode. For
more information, see
.
To exit rescue mode, try one of the following options:
•
Disconnect and then re-connect the power to the device.
•
Upload new valid firmware,
see "Updating firmware", page 80
.
NOTICE
If the device enters rescue mode on multiple occasions and the reason is unknown,
please contact 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.
