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 8, Electronic Iris and DC Lens Level Adjustment Potentiometer.

(5) Line Lock Phase Adjust Potentiometer

When the camera is in line-lock mode, it is possible to adjust the point on the power supply AC cycle at which the camera triggers. This feature is provided so that cameras that are connected to different AC power supply phases may still be synchronized.

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 counterclockwise retards the trigger point. The factory default setting is the zero crossing point. If all cameras in a system are on the same AC power supply phase, no line lock phase adjustment should be made.

(6) Direct Drive/DC Drive Lens Connector

This 4-pin connector supplies the power and DC control signal for use with DC drive auto-iris lenses. If the lens does not have a DD plug installed, wire the lens to a suitable plug in accordance with the diagram below:

(7)Back Focus Adjustment Screws

These two adjustment points, located on the camera body top and side, 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.

(8) 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 peak-to-peak video output.

If a camera is used with a manual iris or fixed iris lens, and the electronic iris is switched ON, this potentiometer controls the electronic iris level. The potentiometer is factory set to give a 1V peak-to- peak video output for a typical scene. The level should not be adjusted unless absolutely necessary.

(9a) Supply Voltage Terminals (MC3820-2X and MC5720-2X)

CAUTION

Only connect the camera to a class 2 power supply.

This terminal accepts 11-40 VDC or 14-30 VAC 50 Hz power source. The terminals are quick- release type. To connect a cable, press the appropriate release lever and insert the end of cable. Ensure that there is a sufficient length of bare wire to make contact with the connector. Also ensure that the cable insulation is not too thick, preventing the cable from being properly inserted.
