8. OPERATIONS
8-1 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. The CMOS
image sensor is positioned on the cooling side, and cooling is done by discharging the
heat from the heated surface. This cooling method is passive air-cooling.
(2) Ambient temperature
The recommended ambient temperature for camera operation is between 20 ºC and
25 °C. Thus, 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
in order for cooling to be effective.
(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’s 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 and unplug the AC supply.
Then remove the cause of the overheating.
(4) Fan speed
This camera has a function to change a fan speed in 3 stages [Fast, Middle, Slow] to
suppress camera vibration caused by a fan. Fast speed achieves the maximum air
volume and it is the default factory setting. The usable temperature of this camera varies
depending on the fan speed.
Fan speed can be changed by software which is called, “DCAM Configurator”. (refer to
8-5 “STARTUP DCAM CONFIGURATOR”).
8-2 PREPARING FOR IMAGING
Use the following procedure when starting operating of the camera.
(1) Connect devices as shown in Figure 7-1 before you start operation.
(2) Turn on the computer's power switch.
The cooling temperature becomes stable about 5 minutes after cooling begins.
• When the cables are connected, confirm the power switch of peripheral device is in the OFF position.
