MAC 600 (E) NT

AMP

Compatible lamps

The MAC 600 (E) NT shall be used only with the lamps listed on page 30. Installing any other lamp may damage the

fixture or create a safety hazard.

Maximum usable hours

The risk of lamp explosion increases with usage due to gradual weakening of the quartz envelope. To minimize the risk

of lamp explosion, replace lamps before usage exceeds the rated life by 200 hours or the manufacturer’s stated

maximum service life.

To track usage, reset the

RLAH and RLST counters under the TIME menu when installing a new lamp. See

page 14.

Installation and alignment

WARNING! Disconnect the fixture from AC power before proceeding. Always wear safety goggles to

protect your eyes and allow a hot lamp to cool for at least 15 minutes before removing it

from the fixture.

To install a lamp

1 Remove the 2 thumbscrews securing the lamp-socket assembly to the rear of the head. Pull out the lamp-

socket assembly and remove the old lamp from the socket.

2 Holding the new lamp by its ceramic base (do not touch the glass), insert it fully into the lamp socket.

3 Clean the glass bulb with the cloth supplied with the lamp, particularly if you touched the glass. A clean, lint-

free cloth wetted with alcohol may also be used.

4 Keep the lamp wire between the fins as you insert the lamp-socket assembly into the head. Turn the

assembly counterclockwise to align the holes with the spacer nuts. Replace the thumbscrews and tighten

them by hand.

5 See page 14 to reset the lamp hour (

RLAH) and lamp strike (RLST) counters.

To align a lamp

Align the lamp if light distribution is uneven.

1 Switch on the MAC 600 (E) NT and allow it to reset.

2 Using either a controller or the control module, turn on the lamp and project the light on a flat surface.

3 Center the hot-spot (the brightest part of the beam) using the 3 Allen-head (3 mm) adjustment screws. Turn

one screw at a time to drag the hot-spot diagonally across the field. If you cannot detect a hot-spot, adjust

the lamp until the light is even.

4 To reduce the hot-spot, pull the lamp in by turning all three screws clockwise 1/4-turn at a time until the light

is evenly distributed.

5 If the light is brighter around the edge than it is in the center, or if light output is low, the lamp is too far back

in the reflector. “Push” the lamp out by turning the screws counterclockwise 1/4-turn at a time until the light

is bright and evenly distributed.
