8. OPERATIONS
This camera can be started after setup.
The setting and the control of the camera are operated by the application software.
8-1 PRECAUTION FOR IMAGING
(1) Ambient temperature
The recommended ambient temperature for camera operation is 25 °C.
The maximum temperatures to which the CMOS image sensor can be cooled, and the stability of
the cooled temperature, are affected by the ambient temperature. The ambient temperature
should be maintained at a constant temperature for camera operation is 25 °C.
(2) Protection circuit
This camera’s thermoelectric cooling device is protected by a thermal protection circuit.
If the internal
temperature of the camera becomes abnormally hot, the protection circuit
operates to
inform the user by a buzzer alarm (beep tone) and switch the STATUS lamp in red
while simultaneously cutting the current supply to the Peltier element. As soon as this protection
is implemented, turn off the power switch, unplug the AC supply. Then remove the cause of the
overheating when it is cooled down.
(3) Cooling methods
The camera has two cooling methods, Air-cooling method and Water-cooling method. The
default of cooling method is Air-cooling.
The cooling mode can be changed by software which is called, “DCAM Configurator”. Refer to 11-5
"SWITCHING THE COOLING METHOD OF “DCAM CONFIGURATOR””.
Cooling method
Detail
Air-cooling (Default)
The heated side of a peltier element is cooled by a fan inside the camera.
When the camera is turned on, the fan starts rotating and cooling is started.
Water-cooling
Circulating water cooler (Option) is used for cooling the heated side of a peltier
element. Cooling does not start just turning on the camera. Cooling water
circulation must be started before start operating the camera in water-cooling.
A fan inside the camera does not rotate.
Refer to 12-2 "WHEN USING AT WATER-COOLING” for the details.
When the setting is changed, restart the camera. By restarting, the setting is reflected on the
camera. After cooling method was switched, the camera memorizes the last setting as the
default setting for cooling.
The setting of DCAM Configurator is maintained, even if the power supply of the camera is
turned off.
