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

4.1 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).

1. Slide part A of 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.

3. Strip back the cable jacket approximately 1-1/4

inches (3.2 cm) and separate the individual con-

ductors (item 3).

Figure 1. Connector Assembly

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).

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.

6. Slide part A 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.

Refer to Figure 2 for wiring diagram.

4.2 R300 RACK MOUNT KIT

INSTALLATION

The R300 Rack Mount Kit holds up to three control

modules. Blank filler panels are provided for less than

three modules.

To convert desk top units, perform the following steps

(refer to Figure 3):

1. Disconnect the equipment from its power supply.

2. Remove the feet from the bottom of the unit.

3. Remove the four (4) screws retaining the cover and

remove the cover from the equipment.

4. Loosen the eight (8) screws retaining the front and

rear faceplates.

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.

6. Repeat steps 1-5 for other units or assembly of the

blank faceplate supplied.

7. Install the two straps sandwiching the slotted tabs

as in Step 4, keeping the bent ends outside the body.

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.

9. Align the front and faceplates with each other and

tighten the four (4) screws for each plate.

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

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).

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.

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.

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.
