Temperature control

Goldeye G/CL Technical Manual V4.2.0
Stable
The temperature is stabilized at one setpoint, the camera
operates optimally.
Green (continuous)
Upper limit
•
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.
Red (flashing)
Lower limit
•
The sensor cooler operates below its lower power limit.
•
Under cold ambient conditions, the cooler may not be
required to keep the sensor temperature at the lowest
setpoint.
•
The image correction quality may also deteriorate
during this stage.
Red (flashing)
Alert
•
If the internal camera temperature exceeds the defined
threshold temperature, the sensor and the critical
electronics of the sensor board conduct an emergency
shutdown to prevent overheating. This is called the
Alert state. It is indicated by the LED continuously
glowing red.
•
In case of Alert, the red color of the LED does not
change even if the camera cools down again.
•
The camera can be restarted only manually by
switching the power off and on again. This is possible
only after the camera cooled down sufficiently.
