Replacing Fuses; Changing The Xlr Pin-Out; Changing Lenses; Cleaning The Optical Path - Martin MAC 600E User Manual

Replacing fuses

The main fuse is located above the XLR output and is replaced by unscrewing the holder with a screwdriver or small coin. The
secondary fuses are located on the printed circuit board and are replaced as follows.
1. Remove the printed circuit board as described above.
2. Locate and replace the defective fuse with one of the same rating. The fuses are shown on the PCB
layout diagram on page 24 as F601, F602, and F603. Their values are listed on page 25.
3. Replace the printed circuit board.

Changing the XLR pin-out

1. Remove the printed circuit board as
described above.
2. Position the jumpers for the desired
XLR pin-out as shown.
3. Replace the printed circuit board.

Changing lenses

18° and 65° field angle options are available for the MAC 600/E. (See "Accessories" on page 26.) The lens is mounted on a
snap-lock "lens hood" or front section that attaches easily to the head. Simply release the snap locks and unhook the safety
wire to remove the standard lens front. Hook the safety wire to the same location on the optional front and snap the locks
closed.
The 18° front is longer than the standard front; the MAC 600/E fitted with this option fits only in flight cases produced after
September, 1997. These can be identified by the outside measurements: 894 mm (35.2") from bottom to top, including wheels.
Older flight cases measure 860 mm (34") from bottom to top, including wheels, on the outside.
Verify that the flight case is of the newer type before shipping MAC 600/Es fitted with the 18° long front.

Cleaning the optical path

Cleaning and servicing components in the head is best left to qualified Martin technicians.
To access the optical components, remove the head cover. Remember to attach the internal safety cable when reassembling the
head.
Be very careful if you decide to clean the optical components. The colored surface on the dichroic filters is achieved by means
of special multi-layer coatings and even small scratches in these might be visible. Residues left from cleaning fluids can bake
onto and ruin the component.
Wash dirty lenses and filters with isopropyl alcohol. Rinse with distilled water: mixing the water with a small amount of wet-
ting agent such as Kodak Photoflo will help prevent streaking and spotting. Dry with a clean, soft and lint-free cloth or blow
dry with compressed air. A generous amount of regular window glass cleaner may also be used, but no residues may remain.

Cleaning the fans

To ensure proper cooling of the fixture it is important that the fans are free of dust. Clean the fans with a vacuum or damp cloth
if they are dirty.
