3.13.2 Overtemperature Condition Detected
L304kc cameras have overtemperature protection. If the temperature of the camera’s CCD sensor
rises above 75° C, the clocking circuitry for the 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 clocking circuitry will remain off until the CCD’s
temperature falls to 60° C or less.
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 4.1), 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 has been detected.
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 4-9). If the bit is set to 1, an overtemperature
condition has been detected.
See Section 4.2.1 for an explanation of Inquiry Registers and Section 4.3.1 for an explanation of
using read/write commands.
L
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 if the camera detects an over-
temperature situation. They will remain set to 1 until the condition is corrected, i.e.,
the temperature of the sensor falls to 60° C or less and a camera reset or a power
off/on has been performed.
