6. Installation
Lens mounting
Notice
Avoid contamination of the sensor and the lens by dust and airborne particles when
mounting the support or the lens to the device!
Therefore the following points are very important:
▪Install the camera in an environment that is as dust free as possible!
▪ Keep the dust cover (foil) on camera as long as possible!
▪Hold the print with the sensor downwards with unprotected sensor.
▪Avoid contact with any optical surface of the camera!
6.1 Environmental Requirements
Temperature
Storage temperature -10 °C ... +70 °C ( +14 °F ... +158 °F)
Operating temperature* see Heat Transmission
* If the environmental temperature exceeds the values listed in the table below, the cam-
era must be cooled. (see Heat Transmission)
Humidity
Storage and Operating Humidity 10 % ... 90 %
Non-condensing

6.2 Heat Transmission
Caution
Provide adequate dissipation of heat, to ensure that the temperature does
not exceed +50 °C (+122 °F) at temperature measurment point T.
The surface of the camera may be hot during operation and immediately
after use. Be careful when handling the camera and avoid contact over a
longer period.
As there are numerous possibilities for installation, Baumer do not speciy
a specic method for proper heat dissipation, but suggest the following prin-
ciples:
▪operate the cameras only in mounted condition
▪mounting in combination with forced convection may provide proper heat
dissipation
TT
Measure Point Maximal Temperature
T 50°C (122°F)
For remote temperature monitoring of the camera a temperature sensor is integrated.
Notice
The temperature sensor is able to deliver values of 0°C (32°F) to +85°C (185°F)
Take care that the temperature of the camera does not exceed the specied case tem-
perature +50°C (+122°F).

6.2.1 Emergency shutdown at Overtemperature
To prevent damage on the hardware due to high temperatures, the camera is equipped
with an emergency shutdown. The DeviceTemperatureStatusTransitionSelector feature
allows you to select different thresholds for temperatures:
NormalToHigh: freely programmable value
HighToExeeded: xed value (camera shutdown if exceeded)
ExeededToNormal: freely programmable value, temperature for error-free re-ac
tivation of the camera.
In the DeviceTemperatureStatusTransition feature, the temperatures for the programma-
ble temperature transitions are set.
The Event EventDeviceTemperatureStatusChanged is always generated when Device-
TemperatureStatus changes.
If the temperature rises above the value set at HighToExeeded, the DeviceTemperature-
Exceeded feature is set to True, the image recording is stopped, and the LED is set to red.
For further use, the camera must disconnected from the power supply after cooling down
or a device reset should be carried out.
The sufcient cooling is recognizable when the event EvenDeviceTemperatureStatus-
Changed (Device Temperature < ExceededToNormal) is output.

7.3 Power saving Mechanisms
The camera is equipped with various power saving mechanisms to reduce the power
consumption and to prevent excessive heating.
1. Set the sensor into idle state
If no frame is requested for a specic time (idle time), the sensor is set into idle state. This
reduces the power consumption of the camera.
The sensor is not set into idle state:
▪in Sequencer Mode
▪ in Burst Mode
▪at set Acquisition Frame Rate

2. Dynamic adjustment of the framerate
The frame rate is dynamically adjusted to the current situation. This means that only so
many frames are recorded, as can be transferred via the interface with the current set-
tings (e.g. resolution, binning and pixel format).
This dynamic adjustment only works when the feature Acquisition Frame Rate is deacti-
vated, so the camera takes pictures at FreeRunning Mode.

8.1.2 Shutter
All cameras of the LXC series are equipped with a global shutter.
Pixel
Active Area (Photodiode)
Storage Area
Microlens
Global shutter means that all pixels of the sensor are reset and afterwards exposed for a
specied interval (texposure).
For each pixel an adjacent storage circuit exists. Once the exposure time elapsed, the
information of a pixel is transferred immediately to its circuit and read out from there.
Due to the fact that photosensitive area gets "lost" by the implementation of the circuit
area, the pixels are equipped with microlenses, which focus the light on the pixel.
8.1.3 Digitization Taps
The CMOSIS sensors, employed in Baumer LXC cameras are read out with 16 channels
in parallel.
