2.0 SCOPE

The information contained within this manual covers
the MLZA6DT Motorized Zoom Lens Control.

3.0 DESCRIPTION

The MLZA6DT is a desktop zoom lens control with
auto/manual iris control designed for use with all Pelco
motorized zoom lenses with “ND” or “MS” in the model
number. The servo amplifier contained within the con­trol detects the slightest change in video level and drives
the iris motor to open or close the iris to maintain proper
faceplate illumination.

Front panel switches provide control of automatic/
manual iris operation, zoom and focus functions, with
optional manual control of the iris. Speed and video
level are adjustable through the front panel knob con­trols.
