Setup
Channel selection on motor control units:
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.
For a detailed description of the radio channel setting on
units other than the WCU-3 please refer to the respective
operation manual.
Radio connection troubleshooting
- incorrect modem type (“Yellow“ - “White“ mixed-up)
- wrong channel setting - channel mismatch
- broken antenna or dirty antenna socket on partner units
- too long or too short distance to foreign party radio
units, depends on local conditions
- interfering (illegal) foreign party transmitters
- another WCU-3 already drives the selected lens motor
Control troubleshooting
- Axis lost: confi guration has been changed while the
units have been powered-on -> re-power and calibrate
- Focus or Iris not available in a separate control system:
set both Focus and Iris to Knob control on their respec-
tive control units and re-power the units
- Jerky motor drive: mixed-up LCS connections for old
(-1/2) and new (-3) hand units or motors (see page 22)
5.4 Optional Zoom Control
Connecting the ZMU-3(A) via cable KC 129-S and the
WCU-3 to ZMU-3 bracket (refer to page 10 for order
numbers), the WCU-3 may be expanded to a three axis
lens control system. The ZMU-3(A) will be powered from
the WCU-3 battery in wireless mode.
Only a ZMU-3(A) may be supplied from the WCU-3
battery in wireless operation. Any other connected unit
must have its own power supply.
