Service And Maintenance; Tilt Lock; Service Utilities - Martin MAC III Profile User Manual

Service and maintenance

Warning! Disconnect the fixture from power and allow to cool for 2 hours 45 minutes before
removing any cover.
Important! Excessive dust, smoke fluid, and particulate buildup degrades performance, causes
overheating and will damage the fixture. Damage caused by inadequate maintenance is not covered
by the warranty.
This section lists service and maintenance operations that may be carried out by the user. Refer any
operation that is not described here to a qualified Martin technician.
The MAC III Profile requires routine cleaning. The schedule depends heavily on the operating environment.
It is essential to follow the cleaning guidelines given later in this section.

Tilt lock

Important! Release the tilt lock before
operating the fixture.
The tilt position of the head can
be locked at various angles for
service. Push the lock in
towards the yoke in one
direction to lock the head and
back in from the other side to
unlock the head.
There is no pan lock on the
MAC III Profile.
Important! Release the tilt lock before
packing the fixture in the
flightcase.

Service utilities

The SERVICE menu in the main menu provides utilities for technicians rigging or servicing the fixture:
• 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. If a pan/tilt position error occurs and the system cannot
correct pan/tilt position within 10 seconds, feedback is
automatically disabled.
• ADJUST is for use at the factory and by authorized Martin
Service technicians only. This menu allows dimmer, shutter,
pan and tilt positions to be adjusted after replacement of components, etc. To adjust the default positions
of all the MAC III Profile's effects, use the CALIBRATION menu instead.
Important! Do not enter the ADJUST menu without service documentation from Martin.
• CALIBRATION sets effects to their factory default positions or lets you set new default positions for
calibration purposes. See "Calibrating effects" later in this chapter for full details.
• UPDATE FIRMWARE, updates the firmware (fixture software). For a detailed guide to updating the
firmware, see "Software installation" later in this chapter.
• EVENT LOG gives access to the fixture's log. See next section.
