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.

4.0 INSTALLATION
4.1 CONNECTOR ASSEMBLY
4. The contact pins supplied with the mating connec­tor are the “crimp” type which may also be sol­dered if you so desired (item 4).
Installation and/or testing will require you to assemble the connector parts provided. Fabricate the intercon­necting cable according to the following steps (refer­ence 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 con­ductors (item 3).
5
STEP 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.
6. Slide part A of the cable clamp toward the connec­tor 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.
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.
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.
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 chas­sis 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 op­erate normally. Next, adjust the level of video using the LEVEL knob on the front panel and observing the monitor. As the video level is ad­justed, 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 func­tions by turning the LENS SPEED knob on the front panel and observing their operation as the knob is adjusted.
