Operation
ICU-1 Calibrating
During calibration the ICU-1 learns and memorizes the
end-stops of the iris ring to avoid the mechanical stress of
driving the ring all the way to the end. Any previously
stored end-stops will be erased during calibration.
You should calibrate the ICU-1:
– when setting up
– after a lens change
– after having moved the iris ring while the ICU-1 was
switched off
– after the lens motor and the iris ring gear have been
separated
– if the CAL-LED flashes.
• Push the CAL key ➪ photo on the ICU-1.
While the ICU-1 is calibrating, the yellow CAL-LED will
be illuminated.
If the CAL LED flashes: End stops have not been
defined yet or the lens ring has been turned
while the ICU-1 was switched off and then been
driven to an end-stop. Repeat calibration process!
