Operation
Note: Pay specific attention to the gears when calibrating.
Sometimes the gears can slip because they do
not mesh closely enough,
or the lens motor is not clamped down tight
enough on the support rods,
or the support rods are not clamped tightly
enough on the bridge plate.
If this happens, re-tighten everything.
In extreme cases it helps to push the lens motor
towards the lens while calibrating. This is only
an issue during calibration, as the ICU-1 uses a
lot of torque during calibration.
Setting the ICU-1 Lens Motor Drive Direction
The ICU-1 can perform the proper iris correction only if
the lens motor drive direction corresponds to the OPEN
and CLOSE keys.
Check the current lens motor drive direction by
pushing the OPEN and CLOSE key on the ICU. The iris
should open when the OPEN key is pushed, and close
when the CLOSE key is pushed. If that is not the case,
switch the drive direction switch (labelled L/R) on the
CLM-1 lens motor photo, or on the UMC
photo for CLM-2 lens motors.
