Service And Maintenance; Service Timer - Martin MAC 350 Entour User Manual

Service and maintenance

WARNING! Read "Safety Information" on page 3 before servicing the MAC 350 Entour. Disconnect
the fixture from AC mains power and allow to cool for at least 20 minutes before handling. Wear
heat-resistant gloves before opening the effects access hatch. Do not view the light output from less
than 8.7 meters (28 ft. 7 ins.) without shade 4-5 welding goggles. Work in well-lit conditions. Be
prepared for the fixture to light suddenly if connected to power.
Important! Refer any service operation not described here to a qualified service technician. It is
possible to replace individual LEDs on the LED board, but this operation can cause serious damage
that is not covered by the product warranty and may be carried out only by Martin Service or its
authorized agents.
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.
Important! As with electronic components in general, the MAC 350 Entour's PCBs are sensitive to
ESD (electrostatic discharge). Take precautions to avoid ESD damage before opening the fixture.
Service electronic components at a static-safe workstation only.
To maximize the life of the MAC 350 Entour and protect the investment it represents, the user will need to
clean the fixture periodically, and it is also possible for the user to change color filters, rotating gobos, mains
fuses and update the firmware. All other service operations on the MAC 350 Entour™ 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 use the best-quality materials and coatings available to ensure optimum performance
and the longest possible component lifetimes. However, optical components in all lighting fixtures are
subject to wear and tear over the life of the fixture, resulting in gradual changes in color rendition of dichroic
filters or the specular properties of reflectors, for example. The extent of wear and tear depends heavily on
operating conditions, maintenance and environment, so it is impossible to specify precise lifetimes for
optical components. However, you will eventually need to replace optical components 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.
The manufacturer's LED lifetime data is based on performance under the manufacturer's test conditions. As
with all LEDs, the gradual reduction in luminous output will be accelerated when LEDs are used in a fixture,
where conditions are much tougher than in manufacturer's testing. To maximize LED lifetimes, keep the
ambient temperature as low as possible and drive the LEDs no harder and for no longer than necessary.

Service timer

The service interval timer AIRF in the INFO menu runs whenever the fixture is powered on. The timer can
be reset to zero by pressing the [Up] button for 5 seconds. If it is not reset, the timer will run to a maximum
of 9999 hours and then stay there until it is reset.
A timer alert can be set from 100 - 2000 hours to indicate that a service intervention is required, for
example. The Service LED lights continuously when the number of hours set for the timer alert is reached.
Resetting the timer to zero switches off the Service LED.
