SERVICE
11
Excessive dust, grease, and smoke fluid buildup can result in damage that is not covered by the warranty. Dirty lenses
and filters transmit less light, absorb more heat, and are subject to heat damage. Dirty fans and air vents reduce cooling
and generally shorten component life. This section takes you through the general maintenance procedures and
describes some basic service operations.
Warning!
Disconnect from AC power before removing any cover or part.
Circuit board service
To re pl ace f us es or cha nge the XLR pi n- out
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
Disconnect the fixture from AC power.
2
Remove the top plate from the front of the base.
Do not remove the curved side plates.
3
Unplug the white plastic connectors from the top of the printed circuit board. To unplug a connector, hold the
plastic connector - never pull the wires - and pull it straight off the pins.
4
Grasp the black pins on either end of the circuit board and gently pull it out. You may have to guide some
wires past the motor housing. Be careful not to knock the copper heat sinks.
5
Replace defective fuses with ones of the same rating. The fuses values are listed on page 30.
6
To change the XLR pin out, position the
jumpers for the desired XLR pin-out as
shown.
7
Gently put the circuit board into the base.
You may have to guide some wires past
the motor housing. Push the black pins
down to lock the board in place.
8
Reconnect all wires as shown on page 29. Replace the top cover.
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 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 components.
Wash dirty lenses and filters with isopropyl alcohol. Rinse with distilled water: mixing the water with a small amount
of wetting 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.
