Fixture readouts

DMX input signal
The DMX TEST menu lets you view the DMX values received on each channel. If the fixture does not
behave as expected, reading the DMX values can help you troubleshoot the problem.
Fixture status
The MAC 301 Wash gives fixture status readouts in the INFO menu:
• Current software/firmware version information is available.
• The non-resettable TOT OPERATE TIME counter displays total hours of use since the fixture was
manufactured.
• Temperature readouts from the display panel and power supply unit in the base as well as the driver and
LED PCB in the head are available. In each case, you can view the current temperature and the
maximum temperature reached since the readout was last reset. The maximum temperatures can be
reset individually.

Lubrication

In general, the MAC 301 Wash does not require lubrication. However, depending on use conditions, the
moving parts in the head and zoom mechanisms may eventually require reapplication of lubricant.
Excessive noise during pan/tilt and zoom movement is a sign that lubrication may be required. This
operation can be carried out by a Martin service partner if necessary.

Fuse replacement

Warning! Disconnect from power before replacing a fuse. Replace fuses with ones of the same type
and rating only. Never bypass or bridge a fuse.
The MAC 301 Wash is protected by a main fuse located in a fuseholder next to the power cable entry (see
"Fixture overview" on page 6). US models require a 6.3 amp slow-blow fuse and EU models require a 4 amp
slow-blow fuse.
To replace fuses:
1. Isolate the fixture from power.
2. Use a flathead screwdriver to open the fuseholder and remove the fuse for testing or replacement.
3. Replace defective fuses with ones of the same type and rating only. Replacement fuses are available
from Martin.
4. Reinstall the fuseholder before reapplying power.
If a fuse blows repeatedly, disconnect the fixture from power immediately and consult your Martin supplier.
