5. Camera Malfunction

 

 

WARNING: DO NOT ATTEMPT TO OPEN THE CAMERA HOUSING IN ANY CASE WITHOUT CONSENTING 
                   THE FACTORY.

 

 
Camera malfunction rarely happens.  In case camera malfunctions, the following troubleshooting procedures 
would help to minimize the problem; it definitely helps the user to find out the actual problem and may save a trip 
for sending the camera back to the factory. 
First of all, disconnect the 12-pin Hirose power connector and BNC cable from the camera unit. Make sure there 
is nothing connected to the camera at this time. 
Check the 12V DC power supply at the 12-pin connector cable and make sure it does provide the right voltage to 
the 12-pin connector. 
Make sure to set the camera shutter dial switch back to 0 position and NRM/ASM to NRM location.  
If frame grabber was connected to the camera, disconnect it. 
Now, power up the camera, and connect it to a TV monitor with a BNC cable.  Make sure the monitor and BNC 
cable are good.  Point the camera at a bright scene without a lens on, a blank or bright display should be seen on 
the TV monitor.  Covering the CCD camera with hand or lens cap should see a dark video.  If no video occurs, 
most likely the CCD camera is damaged.  Consult the technical support at the factory. 
If there is video but it is not clean or bad, it is possible that the CCD imager glass is dirty because of the dirt on 
CCD glass surface or the CCD camera is partially damaged.  Use high-pressure air to blow the dirt away if the 
CCD glass is not clean.  If the problem still exists, contact the UNIQ technical support for help. 
If there is video on TV monitor but not with a frame grabber, most likely the problem is from the frame grabber's 
software or hardware.  Consult the frame grabber factory for further details.  If a lens is used, make sure the iris is 
wide open.
