9.2. Aligning the lamp in the optical path
Aligning the lamp in the optical system is achieved via the 3 adjusters at the rear of the projector. This procedure should be undertaken
to maximise output, properly align the lamp in the optical system and to avoid the possible overheating of the internal components due
to the incorrect focusing of the beam onto components not intended to be exposed to this.
Alignment procedure
Alignment is effected by the 3 adjusters
A
,
B
and
C
located on the lampholder assembly. The lamp should be on, black-out and dim-
mer fully open, and no colours selected. If the lamp is not correctly aligned, a hot-spot will be readily noticeable. Using the 3 adjusters
in unison, you will need to bring the hot-spot to the centre of the beam (adjusters
B
and
C
) and then flatten the beam to maximum
uniformity (adjuster
A
).
A thermal sensor in the body of the
Panorama Power MK2
protects the unit against overheating.
The thermal sensor operates by removing voltage to the lamp if the ambient temperature rises above a preset maximum due to either
less than ideal air circulation around the fixture or in the event of cooling fan failure.
Whilst every possible precaution has been taken to ensure the trouble-free operation of your
Panorama Power MK2
, the following
periodic maintenance is highly recommended.
11.1. Periodic cleaning
Protection lenses and reflectors
Even a fine layer of dust can reduce the lumious output substantially and alter beam characteristics. Regularly clean all diffusion filters
on the projector. In order to do this correctly, it is necessary to remove the filters, as described in section
4.5 Adjusting beam angles.
Cleaning may be achieved using a soft cotton cloth dampened with a specialist lens cleaning solution. Reflectors may be cleaned using
the same materials and should be carried out by qualified personnel.
11.2. Periodic maintenance
Lamp
The lamps should be replaced if there is any observable damage or deformation due to heat. This will avoid the danger of either lamp
exploding. Access to the lamps is as described in section
9.1 Lamp installation and alignment.
ATTENTION!!
Always remove mains power and ensure the unit is sufficiently cooled prior to opening up the housing.
