5.2 CAMERA DISASSEMBLY
The RS-485 CEX-HD Camera Assembly is fairly easy to disassemble.
1)
Remove the stainless-steel snap ring retaining the rear end bell to the
camera housing.
2)
Remove the seal screw in the rear endbell.
Next Very Carefully:
3)
Use a standard air chuck (preferably with a rubber tip) to slowly pressurize
the housing until the camera slides out the back. Do not pressurize too
quickly or the camera may tend to become airborne as it exits the housing.
4)
Once the camera electronics assembly is out of the housing it should be
placed on a non-conductive surface and secured to prevent accidental
damage.
5.3 CAMERA OPERATIONAL CHECKS
Fuse F1 on the electronics interface board assembly should be checked for continuity. F1
is a 1.25A 32VDC fuse element that protects the camera module from excessive loads and
in the event of accidental shorts to camera power or control lines. If F1 is open or has an
impedance greater than 10ohms, it can be removed and replaced by soldering the
component off the board. Naturally, before powering up the camera again, the cause of the
output overload should be identified and corrected.
5.4 CAMERA TROUBLESHOOTING
Check if the indicator LED (D3) on the 54-00446 is turned on. If the indicator LED is not
turned on and F1 has an impedance of less than 3 ohms the 54-0046 circuit board may
have to be replaced, ROS' Technical Services Department should be contacted for
assistance.
