2.0 SCOPE
4.0 INSTALLATION
The information contained within this manual covers
the installation and operation of Pelco TVJ6AC-1 and
TVJ6MS-1 motorized zoom lenses.
Installation should be in accordance with all applicable
local and national electric codes, utilizing approved
materials only.
Please thoroughly familiarize yourself with the information in this manual prior to installation and operation.
3.0 DESCRIPTION
Pelco’s TVJ6AC-1 and TVJ6MS-1 are 2/3" format
motorized zoom lenses designed to provide remote
control of zoom, focus and iris functions on the
TVJ6MS-1 lens, and zoom and focus only on the
TVJ6AC-1 lens. These lenses feature color corrected
professional quality optics.
The TVJ6MS-1 is equipped with a tapered neutral density spot filter as an integral part of the lens to permit
light attenuation beyond the normal range of a zoom
lens down to f360. The spot f ilter is densest to ward the
center and decreases toward the circumference, permitting operation of low-light level cameras in brightest
daylight down to minimum required faceplate illumination.
4.1 CABLE DISTANCES
The following distances are for reference only and are
the approximate maximum recommended under the following conditions:
— 30mA maximum at 12 VDC
— Single lens function activation
— Single common conductor in lens cable
— 10% loss in voltage
22 Awg to 1,236 feet (377 m)
20 Awg to 1,968 feet (600 m)
18 Awg to 3,133 feet (955 m)
16 Awg to 4,974 feet (1,516 m)
NOTE: Video limited to 500 feet on RG-59
coax cable without equalization amplifier .
4.2 WIRING
4.2.1 TVJ6AC-1 Motorized Zoom Lens
This lens features a spot filter and internal auto-iris
circuitry for use with low-light level CCTV cameras.
The auto-iris circuitry must sample either composite or
non-composite video from the camera and be supplied
with 9 to 18 VDC. Functions are on a separate cable.
The TVJ6AC-1 is equipped with a ta pered neutral density spot filter and internal automatic iris electronics
for fully automatic iris operation on low-light level
CCTV cameras.
Models with the letters “LPP” in the part number are
equipped with potentiometers for the zoom and focus
drive motors, pro viding a means for preset positioning
commands from a microprocessor based control unit
to automatically drive zoom and focus functions.

This adjustment is initially set at the factory and in most
cases will not require further adjustment. If, however,
after installation is complete it is determined that further adjustment is necessary, please follow the procedures as outlined below:
1. With the camera installed in its operating location, interconnect it to a video monitor.
2. Locate the adjustment potentiometer access hole
identified on the lens body as LEVEL and remove
the dust plug.
3. Using a small standard or Phillips screwdriver,
adjust the LEVEL potentiometer while at the same
time viewing the picture on the video monitor , rotating counterclockwise for a brighter picture or
clockwise for a darker picture. This adjustment
should be done in very small increments of rotation, pausing between each rotation allowing the
auto iris to react and adjust.
4. With adjustment complete, ensure replacement of
dust plug.

4.4 MOUNTING ZOOM LENS ON CAMERA
Pelco motorized zoom lenses can be easily mounted on
any CCTV camera with a standard 16 mm “C” mount
by carefully screwing the lens onto the camera. These
lenses are designed with self-orienting friction type “C”
mounts. T o obtain correct orientation after threading lens
onto camera, gently continue rotation beyond the point

where lens and camera threading rotation stops. At this
point you will feel the self-orienting action begin. Continue rotation until proper alignment is obtained.
5.0 MOUNTING THE LENS
IN AN ENCLOSURE
Follow the mounting instructions provided with the
enclosure. Cameras with a low optical centerline or
using a large diameter lens will require an elevation
block for proper elevation and mounting within the
enclosure.
IMPORTANT: Set focus for shortest distance (focus near) to extend the lens to maximum length before positioning camera/lens
combinations. This will ensure that the lens has
enough clearance and will not come in contact
with the window during focusing.
4 Pelco Manual C707M-B (11/96)
6.0 TRACK ADJUSTMENTS
8.0 MODELS
In order for a zoom lens to hold tracking focus through
the full zoom range, the effective distance from the
banking shoulder of the mounting thread to the image
plane of the camera (faceplate of Vidicon) m ust be 0.690
inches. This is a screwdriver adjustment on most cameras and is referred to as the “mechanical focus adjustment” (see Figure 3).
If you find that your camera system does not hav e sharp
focus upon installation, follow these procedures to adjust the focus:
1. Select an object as a focusing target at least 75100 feet from the camera/lens.
2. Open iris (aperture) to fully “open” position.
3. Zoom lens out to maximum “tele” position, and
adjust lens focus for sharpest picture.
4. Zoom lens back to the “wide” position, and adjust
mechanical focus on the camera for sharpest picture.
5. Repeat steps 3 and 4 until focus is sharp through
the full zoom range.
7.0 CARE AND MAINTENANCE
Field maintenance of motorized zoom lenses is not recommended. However, if maintenance or repair should
be required, consult Pelco or a qualified service technician.

8.1 RECOMMENDED CONTROLS
MLZ6DT Desk top lens control module de-
signed for remote control of
zoom, focus, and iris functions
for motorized zoom lenses.
Speed control is adjustable from
the front panel. This control can
also be used with TVJ6AC-1
lens, however, the iris will not
be controllable. See Figure 1 for
system configurations.
MLZA6DT Desk top zoom lens control with
auto-iris servo circuitry. Provides auto-iris operation to the
TVJ6MS-1 lens if auto-iris function with manual override capability is required. Not for use
with TVJ6AC-1 lens.
