General Description 3.3 Common Operating Procedures The pushbuttons on the front allow access to the main functions. ON RUN CAL CLM-3 Lens Motor Operation: Due to its very high torque, the CLM-3 motor needs special attention in usage. Careless calibration or mounting may ruin lens mechanics! To minimize the risk of lens damages, any ARRI CLM-3 capable lens control system with a CLM-3 connected, sends a CAL request every time a CLM-3 drive unit has been repowered.

Operation 4. Operation Backlight Menu Slide in the battery into its compartment. Switch on the WCU-3 using the blue ON button. The display illumination can be adjusted to 3 brightness levels or may be switched off completely. Select the desired brightness level, press, then highlight the EXIT symbol and press to return to the Status Screen. The Status Screen appears and the WCU-3 tries to connect to a matching partner unit. If ok, CALibrate the lens motor(s) and the WCU-3 is ready for operation.
The Options Screen holds special user dependent functions as well as the Software Version information. EXIT symbol Button Usage programs the LIM buttons to either setting Limits or adding Lens Scale Offset used in UMC-3(A) 3D applications or correction of Lens Data Archive scales. Knob controls either the Focus or Iris lens motor. The respective other axis will be directed to the Slider. Knob and Slider may be set to clockwise or counter-clockwise direction operation.
Operation Motor Torque Limit Menu Torque Adjustment Instructions In this screen the CLM-3 motor torque can be adjusted in four steps. The adjustment is only available if a motor with high power drive is detected (UMC-3A, ARRIFLEX 416 PLUS (HS) or ALEXA Plus/Studio) high value (4) - high torque - low value(1) - low torque Please select the required torque level carefully: Higher torque levels should be used for rough-running lenses.
Message Descriptions Currently no function, reserved for future applications.
Setup 5. Setup 5.2 Selecting the radio channel (“Yellow Radio“) Every time, the control setup has been established or changed, a power cycle and calibration is advisable. The “Yellow“ radio modem in the WCU-3 utilises a specific scheme of constantly changing frequencies, making the connection between the different radio units very robust against interference.
The new “White“ radio has, aside from being available, the advantage of offering more robust transmission through direct sequence spread-spectrum and adjacent channel rejection technologies. Thus the “White“ radio is less prone to interference from other wireless devices and can better co-exist with WLAN devices on the set. The “White“ radio modem in the WCU-3 utilises a different transmission scheme compared to the “Yellow“ radio, therefore it is connecting to other “White“ radio equipment only.
Setup Channel selection on motor control units: Control troubleshooting Use the rotary channel selection knob on the LDB-2 (Lens Data Box), the FEM-2, the UMC-3(A) or ARRIFLEX 416 plus(HS). Selector switch number 9 switches the radio modem off, number 8 is reserved for special purposes. Press the LCS button on the ALEXA Plus/Studio, and select the same channel as on the WCU-3.

Setup 5.5 Wired setup The WCU-3 also allows hard-wired operation via the ARRI LCS-bus. The WCU-3 may be connected to any supported camera, motor controller or lens motor through any standard LCS cable. The “cable“ symbol in the display‘s status line appears, when an external power supply is detected, and “Hardwire“ replaces the radio information. The radio module shuts-off automatically, regardless of its channel setting.

Setup 5.6 Knob Friction Adjustment A unique feature of the WCU-3 is its very smooth knob action. Additionally, the friction is user adjustable. Remove the knob‘s rubber ring. Open the three crossheaded countersunk screws that are accessible now. Pull-off the knob cover. Now you have access to the friction adjustment. Release the knurled head screw and rotate the whole assembly clockwise for stronger friction or counterclockwise for easier action.
Battery Maintenance 6. Battery Maintenance The following batteries are recommended for use with the WCU-3: SONY NP-FM Series (e.g. NP-FM 500H) Recommended Charger: SONY BC-VM50 For safety purposes, only use the recommended charger and battery types.
