8. OPERATION
8-1 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
FL-280 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 20 °C. Thus, the
maximum temperatures to which the FL-280 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
A double protection circuit protects this camera’s thermoelectric cooling device. If the
heat dissipater becomes abnormally hot, the protection circuit sets off a buzzer alarm
from the camera while simultaneously cutting the current supply to the peltier element.
When the protection circuit operates like this, immediately turn off the power switch.
Then locate and remove the cause of the overheating and restart.
8-2 PREPARATION 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 15 minutes after cooling begins.
•
When the cables are connected, confirm the power switch of peripheral device is in the
OFF position.
8-3 END OF IMAGING
Carry out the procedure below when imaging is finished.
(1) End the imaging or transmission of image data with the application software.
(2) Turn off the power to the peripheral device.
