MAC Ultra Performance Safety and Installation Manual
6. Place the clean air filter into the space in the head, making sure that there is no gap for air to pass
through around the edges of the filter.
7. Hook the rear end of the filter cover into the head and push the front end of the cover into the head until
its clip engages fully. Check that the cover is held securely and cannot fall out of the head.
8. Release the tilt lock before applying power or packing the MAC Ultra Performance in its flightcase.
Lubrication
The MAC Ultra Performance does not require lubrication under normal circumstances. Moving parts can be
checked and a long-lasting Teflon-based grease reapplied by a Martin service partner if necessary.
Service utilities
The fixture’s
SERVICE
menu provides utilities for technicians rigging or servicing the fixture (see the MAC
Ultra Performance User Guide for full details of the control panel menus):
•
ERROR LIST
displays a list of any status messages stored in memory. Up to 20 messages can be
displayed.
•
FAN CLEAN
lets you set cooling fans to run at high speed to remove loose dust.
•
PAN/TILT FEEDBACK
lets you disable feedback to the fixture software from the pan, tilt and effects
positioning systems.
- If feedback is set to
ON
and a pan, tilt or effect position error is detected, the shutter closes and the
effect resets.
- This feature can be disabled by setting feedback to
OFF
. The
OFF
setting is not saved when the fixture
is powered off, and the system will be re-enabled the next time the fixture starts.
•
ADJUST
is for use by Martin Service only.
Important!
Do not use the items in this menu without guidance
or service documentation from Martin Service.
•
For details of the
CALIBRATION
menu, see next section,
•
USB
provides two utilities:
-
USB
→
FIRMWARE
lets you update the firmware (fixture software) from a USB flash memory drive. For
a detailed guide to updating the firmware from a USB drive, see ”Installing using a USB memory
device” later in this chapter.
-
USB
→
SERVICE LOG
(available from firmware version 1.2.0 which is due for release mid-2021) lets
you save the fixture ID, current counter values and status messages stored in the fixture’s memory to a
USB flash memory drive. You can also delete all the status messages permanently from the fixture’s
memory.
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. You can also use calibration to fine-tune fixtures for a particular
location or application.
The
SERVICE
→
CALIBRATION
menu lets you define offsets in the fixture software to adjust the positions
of pan, tilt and effects relative to the DMX values the fixture receives. This allows you to fine-tune fixtures
and achieve uniform behavior in multiple fixtures.
We recommend the following procedure:
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.
