Service utilities
Status messages
The MAC One features a self-diagnostic system that detects any issues concerning correct operation or
safety (temperature that exceeds safe level, for example) and communicates the issues as status
messages or warnings. These messages can be useful in connection with service and maintenance. Error
messages appear in the fixture’s control panel display, but you can also call them up via RDM.
It is possible to:
• Call up a list of up to 20 status messages that the fixture has stored in memory.
• View information on the messages.
• Clear the stored list of status messages.
Fan clean function
The fan clean utility is available using the onboard control panel, RDM or P3. It activates a sequence that
runs fans at full speed in order to remove dust and dirt. This function will not clean fan blades completely,
but it can remove the worst of any accumulated dust.
Disabling pan and tilt feedback
The fixture features pan/tilt position feedback sensors to ensure accurate positioning of the head. Pan/tilt
feedback is enabled by default. If you experience unexpected positioning behavior, it can be useful to
disable the feedback system.
You can disable the pan and tilt feedback system using the onboard control panel only.
Calibration
Martin fixtures are adjusted and calibrated at the factory, and further calibration should only be necessary
if fixtures have been subjected to abnormal shocks during transport or if normal wear and tear has
affected alignment after an extended period of use. However, you can use calibration to fine-tune fixtures
for a particular location or application.
Calibrating effects using the onboard control panel
The SERVICE → CALIBRATION menu lets you define values in the fixture software to adjust the positions
of pan, tilt and effects relative to the DMX values the fixture receives. Creating calibration offsets like this
allows you to fine-tune fixtures and achieve uniform behavior in multiple fixtures.
We recommend the following procedure to adjust the fixture’s calibration settings:
1. Aim a reference fixture and the fixtures that you want to calibrate at a flat surface. You can calibrate
fixtures one at a time or line up multiple fixtures in a row. Apply power and set pan, tilt and effects to
the same DMX values.
2. In each fixture, scroll through the effects in the SERVICE → CALIBRATION menu and adjust the
position of any effects that need calibration while comparing the light output with the reference fixture.
The calibration range available varies depending on the effect.
3. After selecting a value, press ENTER to confirm. The fixture will remember any new calibration values
that you have set, and the new positions will not be affected by powering the fixture off and on. To
return to the list of effects, press MENU.
Loading factory default calibration values
The fixture keeps the original factory-set calibration values in memory. You can erase any custom
calibration values that you have defined using the procedure outlined above and reload the default factory
calibration values at any time by applying a SERVICE → CALIBRATION → LOAD DEFAULTS → LOAD
command.
