3. General Description

The ZMU-3 is shaped like a classic handgrip zoom controller and has the classic zoom knob that assistants‘ thumbs all over the world are familiar with.

Main features

•

•

•

Classic shape zoom controller for ARRI Wireless Remote System

Film and Video/HD compatible

Flexible usage options:

- plugs directly into video lenses

- plugs directly into CLM motors

- plugs into UMC for wired use

- connects to WMU-3 for wireless use

Contrary to its classic exterior, under the hood it is equipped with the latest technology. Zoom speed can be precisely adjusted and zoom limits can be set. A large bar graph shows the zoom ring position, the zoom speed and various status messages, and a ZAP button allows for a quick focus check. A switch changes the running direction of the attached lens motor. Of course the RUN switch can start film cameras, but the ZMU-3 can also start/stop some high end video camcorders and control the zoom motor on various video lenses.

If only zoom is required, the ZMU-3 can be connected with a cable directly to an ARRI CLM-1 or CLM-2 lens motor and to the camera. If focus and/or iris are also to be used, the ZMU-3 can become part of the cabled

ARRI Lens Control System (LCS) or of the ARRI Wireless

Remote System (WRS) by being connected to a Universal

Motor Controller UMC-1, Universal Motor Controller

UMC-3, Lens Data Box or FEM-2.

For wireless use, the ZMU-3 becomes part of the ARRI

Wireless Remote System. Via the Wireless Zoom Bracket

WZB-3 it attaches to the Wireless Main Unit WMU-3.

The special shape of this bracket allows the assistant to position the ZMU-3 in relation to the WMU-3 to suit his/her personal preference.

The ZMU-3 finally allows an ARRI LCS and WRS compatible zoom controller to be attached to the tripod handle. This can be done either using the ZMU-3 Pan

Handle (K2.65006.0) or with the rosette on the right side of the ZMU-3 (M6 thread).

4. Setup

Prior to the operation of the ZMU-3, make sure that

- the support rods are securely fastened to the camera,

- the motor units are securely fastened to the support rods

- and the motor drive gear engages the lens gear ring

with as little play as possible.

power supply will be provided by the Video Camera.

WMU-3:

Use KC 105-S for the connection between ZMU-3 and a WMU-3 Wireless System. The WZB-3 bracket enables ergonomic mount of the ZMU-3 in this application.

LCS Bus:

Use cables KC 92-S (0,8m), KC 93-S (10m) or KC 112-S for the connection between ZMU-3 and LCS bus devices like CLM-1, UMC-1, UMC-3, ARRICAM Lens Data

Boxes LT/ST or 435 FEM-2. Power will be provided through the LCS-bus.

Note: WMU-3 Software version 1.02 or above is necessary for wireless operation of the ZMU-3 with all display functions.

The ARRIFLEX 435 Advanced/Xtreme must not be connected with the following cables:

LC-S1, LC-S2, LC-A1, LC-A2, LC-A3, LC-C1, LC-C2.

CLM-2 Motors:

Use KC 91-S for the connection between ZMU-3 and a

CLM-2. The power will be supplied through any ARRI RS socket.

Video Lenses (analog controlled):

Use KC 90-S for the connection between ZMU-3 and an analog controlled Video Lens (e.g. Fujinon). ZMU-3

5. Operation of the ZMU-3

5.1 Switching on

The ZMU-3 has no dedicated power-switch.

Power-on the ZMU-3 using the power switch of the connected supply source (Camera/UMC/WMU-3) or connect the appropriate ZMU-3 cable to the unit.

After connecting to the RS/LCS socket three lines briefly flash up in the speed display ( ➪ image A).

The zooming speed previously used is then shown on the display. The status display indicates ready with the rdy display ( ➪ image B).

In case a zoom range was previousely stored this is now shown on the marking display ( ➪ image C).

• The lens motors must be calibrated in case this had not been done before, or the lens settings have been changed while switched off. Press the LENS CALbutton on the ZMU-3 ➪ image to calibrate the endstops.

• Select the desired drive direction with the drive direction switch on the ZMU-3

➪ image

.

Note: If operated together with a FEM-2/UMC/LDB the drive direction can also be changed on these units.

5.2 Calibration

The end stops of the zoom ring are defined and stored during the automated calibration process in order to prevent driving the lens ring up against the lens' end stops. Previously set values are thereby erased.

Calibration must be carried out

- during initial set-up,

- after a lens change,

- after the lens ring has been manually moved

while the units were disconnected from the power,

e.g. after an extended break

- after the motor drive gear has been removed from the

lens control ring.

5.3 Battery control (BAT)

An illuminated or flashing bat symbol on the status display of the ZMU-3 indicates that the battery must be exchanged or recharged ( ➪ image E).

• Press the LENS CAL -button ➪ image on the ZMU-

3 to start the calibration process.

During calibration the cal-symbol is illuminated on the display ( ➪ image C).

The cal symbol flashes:

Lens end stops are not yet defined, or the lens has been moved while the LCS was switched off and then driven against the end-stops.

Recalibrate! ( ➪ image D)

Do not begin any new takes!

5.4 Zooming

• Press the zoom lever ➪ image in the desired direction.

The focal length will be altered. The greater the force, the faster the zoom will react.

5.4.1 Setting zoom speed

The sensitivity of the zoom lever (zoom speed) can be adjusted and is indicated on the speed display of the

ZMU-3. The smaller the value the lower the maximum zoom speed will be.

• The + and - buttons on the ZMU-3 are used to set the zoom speed. Pressing the + or - button briefly will change the speed setting in increments of 1, pressing the buttons longer will alter the speed in increments of 10. The zooming speed can be set within a range of 1 and 100 ( ➪ image G, H).

Note: Various modes of joystick responding behaviour are available. Please see section 6.3 and 6.4 for details.

5.4.2 ZAP-function

5.4.3 Defining the zoom range

For zooming, a defined range can be selected and stored.

• Drive the zoom to one end of the selected range.

• Press the SET-button ➪ image and keep it held down. The LENS and ANGLE symbols are flashing

( ➪ image J).

• Drive the zoom to the other end of your selected range and release the SET-button. The LENS and

ANGLE symbol will now be illuminated. The zooming range is indicated on the marker display

( ➪ image K).

• When one end stop is reached (zooming lever not pressed) the complete bar of the marker display flashes towards the end of the reached range

( ➪ image L).

• If one of the defined end stops is reached while zooming (zooming lever is pressed), the LENS and

ANGLE symbol and the position marker will be flashing ( ➪ image M).

5.4.4 Erasing the zoom range

• Press the RESET-key ➪ image and hold it briefly.

The LENS and ANGLE symbols will disappear.

– intermediate switching ON permanent switching ON

24V ARRI cameras are started with the intermediate switching on function. In camera RUN this is indicated on the status display of the ZMU-3.

Note: The permanent switch-on function is available on the ZMU-3 socket. Please contact your ARRI Service

Center for details.

5.6 Video lenses

The ZMU-3 can be connected to video lenses with the cable KC-107 (K2.65041.0).
