9. OPERATIONS
9-1 OPERATING PRECAUTIONS
Be careful of the following when you operate the camera.
(1) Cooling method
Cooling of this equipment is done using a Peltier element.
With a Peltier element, when current is supplied, one surface is cooled, and the other surface is
heated. CMOS image sensor is positioned on the cooled side, and cooling is done by discharging
the heat from the heated surface.
The camera has two cooling methods, Air-cooling method and Water-cooling method.
The default of cooling method is Air-cooling. Cooling mode can be changed by software which is
called, “DCAM Configurator”. (refer to 9-5 “STARTUP DCAM CONFIGURATOR”).
Cooling method
Detail
Air-cooling method
(Forced air-cooled)
(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 method
Circulating water cooler (Optional) 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.
•
See 8 “WATER COOLING” for instruction of water-cooling.
•
Do not switch to water-cooling method when water-cooling is unnecessary.
(2) Ambient temperature
The recommended ambient temperature for camera operation is 20 °C.
Both water-cooling or air-cooling are available as cooling method, CMOS image sensor cooling
temperature is more stable under water cooling operation.
(3) 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 lighting the camera red LED light 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.
