1.3 - Lamp installation
ATTENTION! This fixture is designed exclusively for use with Philips MSR 1200SA lamps. NEVER
USE ANY OTHER TYPES OF LAMPS.
•
Disconnect the power supply before carrying out any work on the fixture.
•
Make certain that the fixture is off and the temperature of the components can't cause burns (wait at least 20
minutes after switching off).
•
Never carry out any work if the fixture doesn't have its protective covers or its lenses are damaged. Discharge
lamps can explode.
•
Never look directly at the lamp when it's lit - discharge lamps emit UV rays which are dangerous for sight.
There's an optical group in the fixture's moving head. Follow these instructions when fitting or replacing the lamp.
1.
Disconnect the power supply and wear protective gloves and glasses.
2.
Remove the head's top cover
3. (fig.1)
Unscrew the two locking screws (A) on the aluminium support which fix the lampholder base to the optical group
4. (fig.2)
Raise the aluminium support and fit the lamp in the base. Avoid touching the lamp bulb with your fingers. Should this
happen, clean it before use with a soft cloth and alcohol, then clean with a dry cloth.
5. (fig.3)
Tighten the screws again, making certain that the lamp wires are positioned in the appropriate slots.
6.
Close the cover again.
1.4 - Lamp Alignment
After each relamping, it's important to align the lamp with the optical group in order to obtain maximum uniformity and light output.
1. Fit the new lamp, close the fixture and switch it on.
2. Connect the fixture to a lighting console.
3. Point the fixture at a flat surface (if possible light coloured) at a distance of at least 3metres.
4. Set the control channels in such as way as to obtain the projection of a white beam. Then: IRIS open, DIMMER at maximum luminosity,
suitable FOCUS, no GOBO or COLOR projected.
5. (Fig.4) Loosen the two fastening screws (A) and use the knobs on the sides to align the lamp horizontally.
6. (Fig.5) Use the large centre brass ferrule to align the lamp vertically with respect to the optical group.
7. The lamp is aligned correctly when a uniform beam is obtained, without any shadows or zones which are brighter than others.
8. (Fig.6) Tighten the fastening screws and close the cover again
