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 con-
trol 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 con-
trols.

4.0 INSTALLATION
4. The contact pins supplied with the mating connec-
tor are the “crimp” type which may also be sol-
dered if you so desired (item 4).
4.1 CONNECTOR ASSEMBLY
Installation and/or testing will require you to assemble
the connector parts provided. Fabricate the intercon-
necting cable according to the following steps (refer-
ence Figure 1).
5. After crimping or soldering the contact pins to the
conductors, push them into the proper holes in the
connector until they snap in place.
NOTE: Contacts cannot be removed from the
connector without the use of the appropriate
AMP extraction tool which is available from
Pelco.
1. Slide partAof the cable clamp (item 1) over the end
of the cable (item 1, part C) with the threaded end
of the cable clamp facing the connector (item 5).
2. If the cable has a diameter less than 1/2 inch (1.3
cm), slide the rubber boot (item 2) over the end of
the cable and pull through the cable clamp to so
that the boot encases the cable and forms a good
seal.
6. Slide partA of the cable clamp toward the connec-
tor and screw the parts together.Attach part B (item
1) onto part A and connect both parts with the
screws provided.
7. Connect the cable assembly to the unit and seat
the connector by twisting the locking collar until it
snaps into position.
3. Strip back the cable jacket approximately 1-1/4
inches (3.2 cm) and separate the individual con-
ductors (item 3).
Refer to Figure 2 for wiring diagram.

4.2 R300 RACK MOUNT KIT
INSTALLATION
5. Insert the chassis into the rack body; sandwich the
rack body slotted tabs between the chassis and the
front plate, and the chassis and the rear plate.
The R300 Rack Mount Kit holds up to three control
modules. Blank filler panels are provided for less than
three modules.
6. Repeat steps 1-5 for other units or assembly of the
blank faceplate supplied.
To convert desk top units, perform the following steps
(refer to Figure 3):
7. Install the two straps sandwiching the slotted tabs
as in Step 4, keeping the bent ends outside the body.
1. Disconnect the equipment from its power supply.
2. Remove the feet from the bottom of the unit.
8. Attach the straps and rack body to the chassis with
two (2) cover screws, when applicable. If no chas-
sis is placed in either side port of the rack, a screw
and nut must be used to attach the strap and body
together.
3. Remove the four (4) screws retaining the cover and
remove the cover from the equipment.
9. Align the front and faceplates with each other and
tighten the four (4) screws for each plate.
4. Loosen the eight (8) screws retaining the front and
rear faceplates.
10. Repeat step eight (8) for the rear plates.
11. Reconnect the unit to its power supply.

5.0 OPERATION AND SYSTEM TEST
5.1 SYSTEM TEST FOR MLZA6DT
5. For Auto operation, put the power switch in the
AUTO/ON position. The IRIS switch should not
operate; ZOOM and FOCUS switches should op-
erate normally. Next, adjust the level of video
using the LEVEL knob on the front panel and
observing the monitor. As the video level is ad-
justed, the iris should open or close depending on
whether video display is bright or dark.
1. Hook up the cable between the output connector
on the MLZA6DT and the input connector on the
lens (see Figure 4).
2. Connect the video cable from the camera to the
VIDEO LOOP-THRU on the rear panel and to the
monitor (see Figure 4).
6. Test the control for fast and slow speeds of all func-
tions by turning the LENS SPEED knob on the
front panel and observing their operation as the
knob is adjusted.
3. Turn the power switch on the MLZA6DT to the
OFF position, and plug the power cord into a 120
VAC power source.
4. For MANUAL operation, put the power switch in
the MAN position. Observing the monitor, test for
proper operation of zoom, focus, and iris functions
with related switches on the front panel.
