Operational statuses
Table 123 explains the operational statuses that are indicated by the temperature
status LED on the camera back panel.
For TECless cameras, the LED will either remain dark, not indicating any TEC status;
or it will turn red, indicating overheating.
Use an efficient heat removal device
If the camera has switched to
Alert
status, it is also recommended to provide a more
efficient heat sink for the camera housing before resuming operation.
However, additional heat dissipation arrangements are always advantageous.

Status
Description
Off
There are two cases when the LED remains dark:
•
The TEC is actively switched off, using the feature
SensorTemperatureControlMode
.
•
The camera is a TECless camera that has no TEC
available.
Off
Deviated
The sensor cooler is operating, the defined sensor
temperature (setpoint) has not been reached or stabilized
yet. This signal is no error signal.
Green-red
(flashing)
Stable
The temperature is stabilized at one setpoint, the camera
operates optimally.
Green (continuous)
UpperLimit
The sensor cooler operates at its upper power limit. The
cooler is not able to keep the set temperature; however,
the critical temperature level has not been reached yet.
Under warm ambient temperatures, consider red flashing
for an extended period of time as a warning signal: if the
camera keeps working under unchanged conditions, an
emergency shutdown is likely.
The image correction quality may also deteriorate during
this stage.
