6.9 Error Condition Detection
6.9.1 Imaging Sensor Overtemperature Condition
Detected
As described in Section 6.7 on page 144 , the camera includes a temperature sensor that is used to
monitor the temperature of the imaging sensor.
The camera also has imaging sensor overtemperature protection. If the temperature of the
camera’s imaging sensor rises above 75° C, an overtemperature condition will be detected and the
circuitry for the imaging sensor will switch off. In this situation, you will still be able to communicate
with the camera and the camera will still be able to transmit test images, however, no live images
can be generated. The imaging sensor circuitry will remain off until its temperature falls below
60° C. Once the sensor temperature falls below 60° C, the error condition will clear and the camera
will begin to operate normally.
You can check to see if the camera has detected an overtemperature condition with the Camera
Configuration Tool Plus (CCT+) or by using binary read commands from within your own application
to read the camera’s inquiry registers.
With the CCT+
With the CCT+ (see Section 7.1 on page 156 ), you use the Overtemperature parameter in the
Camera Information parameters group to determine if an overtemperature condition has been
detected. If the value is 1, an overtemperature condition is present.
By Reading Inquiry Registers
You check for an overtemperature condition by reading the value of bit 20 in the Camera Status field
of the Camera Status Inquiry Register (see
page 161 ). If the bit is set to 1, an overtemperature
condition is present.
See Section 7.2.1 on page 158 for an explanation of Inquiry Registers and Section 7.3.1 on
page 197 for an explanation of using read/write commands.
Note
The Overtemperature parameter in the CCT+ and bit 20 in the Camera Status
field of the Camera Status Inquiry Register will be set to 1 when the camera
detects an overtemperature condition. They will remain set to 1 until the
condition is corrected and a reset or a power off/on is performed.
