Aligning the lamp in the optical path is achieved by
altering the three adjusters located on the rear of the
fixture.
This procedure should be undertaken to properly align
the lamp in the optical system, thus avoiding the possible
overheating of internal components and ensuring the
maximum luminous output form the fixture.
aligning
Alignment is effected by altering the two adjusters
B
and
C
simultaneously, with the lamp on.
Output from a non-aligned lamp will be noticeable for a
hot-spot; adjustment will bring the hot spot towards the
centre of the beam, flattening it in the process.
Vertical adjustment
Adjuster (
C
) acts on an internal lever and spring
assembly which moves the lamp vertically toward the
centre of the parabolic reflector; rotate it until the cor-
rect positioning is achieved.
Horizontal adjustment
Adjuster (
B
) acts on an internal lever which moves the
lamp horizontally in the centre of the parabolic reflec-
tor; rotate it until the correct positioning is achieved.
Axial adjustment (spot/flood)
Adjuster (
A
) moves the entire lampholder assembly axially within the reflector, rotate it until a flat, even beam is produced, with
no noticeable hotspot.
This procedure may be useful in situations
where the
Fiera
575 EB
may need to be
switched on in an enclosed space, such as in
its flight case.
1) Turn on the projector whilst holding down the
enter
,
menu
and
–
buttons simultaneously.
The projector will perform a reset of its elec-
tronic systems without any motor movement.
2) You may alter the DMX address or any other
parameter at this point without any articula-
ted movement.
3) To return to normal operation of the
Fiera
575 EB
turn the unit off and on via the
power
button, or effect a reset via the menu
system.

575 EB
without articulated movement
Attention/Danger
Adjuster (
A
) can become extremely hot after only a few minutes of lamp operation.
Lamp alignment should be undertaken within 5 minutes of the lamp being turned on.
During this procedure, do not touch the body of the projector.
