Installation Instructions
LENS SETUP PROCEDURES
For manual or fixed iris lenses set the EI switch and AGC switch to ON.
Auto Iris lenses
Switch the EI and AGC off. Refer to the lens instructions and adjust the lens for the optimum
picture (video output level of 1V peak-to-peak). Switch the AGC on.
Direct Drive lenses
Where fitted, switch the EI and AGC off. Use an appropriate screwdriver to turn the lens level
potentiometer (under the hinged flap) fully clockwise. Next, slowly adjust the potentiometer
anticlockwise until the optimum picture is obtained (video output level of 1V peak-to-peak).
Switch the AGC on.
FOCUS ADJUSTMENT
The back focus adjustment screws are located on the top and side of the case and should be
adjusted using an appropriate screwdriver. If possible, always use the top screw to adjust the
back focus mechanism.
Turn the adjuster screw clockwise or anticlockwise to obtain focus. When the focus is sharp,
turn the back focus adjustment screw 2 or 3 turns anticlockwise. The picture will lose sharpness.
Turn the back focus screw clockwise until focus is once again obtained. If you have turned the
back focus screw clockwise past the point of best focus, repeat the procedure.
The last turn
of the back focus adjustment screw must always be in a clockwise direction
. Do not
over turn the back focus mechanism.
Fixed Lenses
Set the lens focus to infinity and view an image greater than two metres away. Focus the image
using the back focus screw. Set the lens focus as required.
Manual Iris Lenses
Open the iris fully and set the lens focus to infinity. View an image greater than two metres
away. Focus the image using the back focus screw. Set the lens focus and iris as required.
Auto-iris and Direct Drive Lenses
Fully open the iris by covering the lens with a suitable neutral density (ND) filter. Set the lens
focus to infinity. View an image greater than two metres away. Focus the image using the back
focus screw. Remove the ND filter and set the lens focus as required.
Zoom Lenses
Set the lens focus to infinity and fully open the iris by covering the lens with a suitable neutral
density (ND) filter. Zoom out to the widest field of vision and view a distant object. Adjust the
back focus screw until the object is in focus. Next, zoom fully in and adjust the lenses focus
until the object is again focused. Repeat these steps until the full zoom range may be viewed
with the minimum loss of focus.
SYNCHRONISATION
Cameras that operate from AC supplies are line-locked for a supply frequency of 50Hz. If the
supply frequency is unstable, then disable the line lock by setting the SYNC switch to
Internal
