Installation Instructions
CONTROLS AND SWITCHES
(4) Electronic Iris (EI)
The Electronic Iris (EI) compensates for excessive light level by automatically adjusting the shutter speed. The electronic iris should be ON when using fixed or manual iris lenses. When using Auto Iris (AI) lenses of either the video drive or DC drive types the EI must be OFF. Also see (10) Electronic Iris and DC Lens Level Adjustment Potentiometer.
(5) Line Lock Phase Adjust Potentiometer
When the camera is in
The line lock phase adjustment potentiometer allows the line lock phase trigger point to be adjusted by ±120O. Rotating the potentiometer clockwise advances the trigger point and turning it anticlockwise retards the trigger point. The factory default setting is the zero crossing point. If all cameras in a system are on the same mains phase then no line lock phase adjustment should be made.
(6 and 7) Line Lock Phase Adjust Buttons (+ Advance; - Retard)
When the camera is in
The line lock phase adjustment buttons allows the line lock phase trigger point to be adjusted by ±120O. Pressing the advance button advances the trigger point and pressing the retard button retards the trigger point. The factory default setting is the zero crossing point. If all cameras in a system are on the same mains phase then no line lock phase adjustment should be made.

(9)Back Focus Adjustment screws
These two adjustment points located on the camera body top and side (top not shown), are used to adjust the back focal length or picture focus. The range of adjustment allows both C and CS mount lenses to be used without the need for a spacer ring. Refer to the section on Focus Adjustment
(10) Electronic Iris and DC Lens Level Adjustment Potentiometer
If the camera is used with a direct drive (DD) lens this potentiometer varies the DC reference voltage used to control the lens. The potentiometer has the effect of increasing or decreasing the lens aperture. This potentiometer should be set to obtain a 1V
If a mono camera (VPM8030, VPM8032, VPM8130, VPM8132, VPM8120 and VPM8122) is used with a manual iris or fixed iris lens, and hence the electronic iris is switched ON, this potentiometer controls the electronic iris level. The potentiometer is factory set to give a 1V
