ZMU-1 / ZMU-2 Zoom Main Unit
ZMU-1 K4.47496.0
ZMU-2 K4.52419.0
The zoom unit ZMU ➪ photo is the main control unit for
all configurations remotely controlled via cable. It enables the
focal length of zoom lenses to be adjusted by remote control.
ICU-1 Iris Control Unit
K2.47028.0
The ICU-1 ➪ photo provides constant exposure during
speed-ramps. It constantly monitors the frame rate of the
camera. During a frame rate change, the ICU-1 will calculate a
new value for the iris to compensate for the exposure change,
and instruct the lens motor to change the iris ring accordingly.
Best exposure is achieved with a WRC-1 on the
ARRICAM or the FEM-2 on the ARRIFLEX 435
Xtreme/Advanced!
Power Supply
The LCS is operated with a separate 24V or 12V battery.
The LCS can also be powered directly from the camera,
provided the rated load of the camera socket is not exceeded.
Cables
A modular cable-connecting system allows easy connection
from one unit to the other, as well as to the system operating
control. The LCS recognises connected units and also
detects defective cables.
System Overview
ZMU-3 Zoom Main Unit
K2.65003.0
The zoom unit ZMU-3 ➪ photo controls the focal length
of zoom lenses on film- or video-cameras wirelessly or
hard-wired. For wireless operation the ZMU-3 must be
connected to the WMU-3. A CLM-2 motor can be directly
operated with the ZMU-3 via the Y-cable KC-91S (K2.65008.0).
Note: When operating with video-lenses, the LC-display
of the ZMU-3 shows the actual zoom speed
instaed of the lens position.
FIU-1 Focus Iris Unit
K2.41383.0
The focus iris unit FIU-1 ➪ photo can be used for remote
focus as well as remote iris control. It is user-friendly and
can be operated on the same principles as the mechanical
follow-focus system. To use an FIU-1, a ZMU is always
necessary.
