4.1 Installing and
Connecting the Lens
Motors
Before connecting or disconnecting electrical
connections, switch off
• the camera
• the Zoom Main Unit ZMU,
• the Universal Motor Controller UMC
• and all Wireless Main Units WMU!
Use only 24V or 12V batteries!
Changing the setting is not necessary. The LCS
automatically recognises the voltage.
At 12V there is however a lower maximum speed
of the lens motors due to the lower torque.
As the end-stops of the iris ring on the
ARRIMACROS change when the lens is focussed,
the ARRIMACROS may not be used with the
LCS or the WRC-1 system.
4.1.1 Selection of lens motors
and their power supply
There are two different lens motors available:
The lens motors CLM-1 have a high torque and should be
used with stiff lenses or in adverse weather conditions.
The lens motors CLM-2 are lighter and smaller. Where light
weight and small size are important, they should be used.
For various lens rings, different motor types can also be
used, for example a CLM-1 motor for the zoom ring and
a CLM-2 motor for the iris ring.
After selecting the control motors, the power supply for them
must be specified. The selection can be made according
to the diagram on the ➪ fold out page in the back of
this manual. In the squares is listed which units and cables
are necessary for the desired application.
The cables listed in the diagram should be connected to
the various units according to the following table:
