MAC 401™ user manual
Service and maintenance
Warning! Read “Safety Information” on page 3 before servicing the MAC 401.
Warning! Disconnect the fixture from AC mains power and allow to cool for at least 10
minutes before handling. Do not view the light output from less than 1 meter (3 feet
4 inches) without shade 4-5 welding goggles. Set the zoom to wide angle and work in
well-lit conditions. Be prepared for the fixture to light suddenly if connected to power.
Warning! Refer any service operation not described in this user manual to a qualified
service technician.
Important! Excessive dust, smoke fluid, and particle buildup degrades performance, causes
overheating and will damage the fixture. Damage caused by inadequate cleaning or maintenance is
not covered by the product warranty.
The user will need to clean the MAC 401 periodically, and it is also possible for the user to remove and
install head modules, change the mains fuses and update the firmware. All other service operations on the
MAC 401 must be carried out by Martin Professional or its approved service agents.
Installation, on-site service and maintenance can be provided worldwide by the Martin Professional Global
Service organization and its approved agents, giving owners access to Martin’s expertise and product
knowledge in a partnership that will ensure the highest level of performance throughout the product’s
lifetime. Please contact your Martin supplier for details.
It is Martin policy to apply the strictest possible calibration procedures and use the best quality materials
available to ensure optimum performance and the longest possible component lifetimes. However, LEDs are
subject to wear and tear over the life of the product, resulting in gradual changes in color and overall
brightness over many thousands of hours of use. The extent of wear and tear depends heavily on operating
conditions and environment, so it is impossible to specify precisely whether and to what extent LED
performance will be affected. However, you may eventually need to ask Martin Professional to replace LEDs
if their characteristics are affected by wear and tear after an extended period of use and if you require
fixtures to perform within very precise optical and color parameters.
Cleaning
Cleaning schedules for lighting fixtures vary greatly depending
on the operating environment. It is therefore impossible to
specify precise cleaning intervals for the MAC 401.
Environmental factors that may result in a need for frequent
cleaning include:
• Use of smoke or fog machines.
• High airflow rates (near air conditioning vents, for example).
• Presence of cigarette smoke.
• Airborne dust (from stage effects, building structures and
fittings or the natural environment at outdoor events, for
example).
If one or more of these factors is present, inspect fixtures within
their first 100 hours of operation to see whether cleaning is
necessary. Check again at frequent intervals. This procedure will
allow you to assess cleaning requirements in your particular
situation. If in doubt, consult your Martin dealer about a suitable maintenance schedule.
Use gentle pressure only when cleaning, and work in a clean, well-lit area. Do not use any product that
contains solvents or abrasives, as these can cause surface damage.
You can set the fixture to issue a time alert after a defined number of operating hours has passed to remind
you to clean it. This is set by default to 999 hours. You can adjust this threshold from 100-999 hours using
the
INFO - AIRF - STTM
menu on the control panel. Whenever the value on the
INFO - AIRF -
TOTL
counter exceeds the threshold set on
INFO - AIRF - STTM
, an alert will be displayed on the
control panel.
