Note also the position of the

. Each time you remove a
goboholder from the wheel, turn the
drive wheel (twice if necessary) until
the marks exactly line up.
We recommend that you only
remove one goboholder at a time.
Avoid turning the drive wheel while
a goboholder is out of the gobo
wheel. This will keep the gobos in
their correct orientation, avoiding
the need to reprogram cues or
adjust gobo positions in the fixture
because a gobo orientation has
changed during service. Note that if
necessary you can adjust the home
positions of rotating gobos at any time using the SERVICE
→
CALIBRATION menu in the control panel.
9. See Figure 16. With the reference marks lined up, lift the outside edge of the goboholder up slightly and
pull the goboholder out of the gobo wheel. Note how the goboholder tongue (arrowed) engages in a
recess in the gobo drive wheel. You will need to reinstall the goboholder with the tongue in the same
position in the drive wheel.
10. For details of replacing a gobo in a goboholder, see the next section of this manual.
11. When reinstalling a goboholder in the gobo wheel, use the above procedure in reverse as a guide.
Do not apply lubricant to the goboholder or drive wheel.
Line up the reference marks in the goboholder and gobo drive wheel and push the tongue correctly into
its location in the gobo drive wheel when you install the goboholder. Check that the goboholder is held
securely in the wheel after you have installed it.
Installing a gobo in a goboholder
All the rotating gobos in the ERA 600 Performance are held in their holders by springs and can be removed
from their holders as described below.
Note that the fused glass gobo Limbo (Crystal) has a specially designed goboholder and spring to cater for
the extra thickness of the gobo. Fused glass gobos, their goboholders and their retaining springs are not
interchangeable with the other gobos and goboholders.
Gobo orientation
Make sure that you install gobos facing in the correct direction, or they may suffer heat damage. The
orientations shown in Figure 17 are correct in most cases, but consult your Martin dealer or gobo supplier if
you are in any doubt about the orientation of a specific gobo type.
