MAC 250™ Beam Kit Installation Guide

Introduction

This Installation Guide explains how to install the MAC 250 Beam™ Upgrade Kit to convert a standard Martin Professional™ MAC 250 Wash™ to a MAC 250 Beam model. Installation only takes a few minutes. A fixture software update is required if the installed software version is earlier than v. 1.4.0.
If you keep the standard components you remove, the MAC 250 Beam components can be uninstalled and the fixture returned to sta nd a rd MAC 250 Wash configuration at any time.
The MAC 250 Beam Kit has part number P/N 91610101. For the latest documentation and information about this and all Martin Professional products, please
visit the Martin website at www.martin.co m.
Warning! The MAC 250 Beam has a much more intense light beam than the standard MAC 250 Wash. Do not u se it to il luminat e an y surf ace c loser t han 3.5 m ( 11 ft. 6 in s.) fr om t he fr ont of the head, or you may create a fire risk.
Make sure that the fron t lens does not face the sun direc tl y f or lon ger than a f e w seconds at an y time during daylight hours. The Beam lens can focus the sun's rays inside the fixture, causing internal damage and creating a possible fire risk.
Apart from the new minimum distance to illuminated surfaces specified above, follow all the other safety precautions in the MAC 250 Wash user manual when installing the MAC 250 Beam Kit and using the modified product. The user manual is supplied with MAC 250 Wash fixtures , and the latest revision of the us er manual is also available for download from the Product Support page for the MAC 250 Wash at www.martin.com
Disconnect the fixture from power and allow to cool for at least 20 minutes bef ore s tarting w ork . The MAC 250 Beam Kit must be installed by q ualified profession al technicians only. Read all of
this Installation Guide carefully before starting to install the Kit. If you have any questions about ho w to install the MAC 250 Beam Kit or use the MAC 250 Beam

• Pozidriv PZ1 and PZ2 screwdrivers
• Torx TX20 screwdriver

Installation procedure

To install the MAC 250 Beam components in a standard MAC 250 Beam fixture:
1. Disconnect the fixture from power and allow it to cool.
2. See Figure 1. Release the head cover retaining screws (arrowed) and remove both head covers. You can either let the head covers hang on their safety cables or unclip their safety cables and remove them completely, whichever is more convenient.
3. Apply the tilt lock with the head topside up (in this position the text on the back of the head is the right way up).
4. See Figure 2. Remov e the four crosshead retaining screws from the front lens assembly and remove the front lens. The screws have Loctite applied at the factory, so take care when removing them. Store the front lens for possible re-use if the fixture is to be returned to standard MAC 250 Wash configuration at a later time. You can send the screws for scrap metal recycling, because new Torx screws are supplied in the Kit.

5. See Figure 3. Fasten the new front lens mounting bracket (P/N 62420240) supplied in the Kit to the front of the head using the four M4 X 12 Torx 20 screws (P/N 08070710) also supplied in the Kit. Apply a v ery small quantity of Loctite to the threads before tightening the screws.
If you reinstall the original front lens at a later date to return the fixture to standard MAC 250 Wash configur ation, r e-use t hes e Torx screws.
6. See Figure 4. Remove t he four screws (arrowed) that hold the ap erture plate in place inside the front of the head. See Figure 5. Remove the aperture plate and install the new aperture plate with shield plate (P/N
23819530) supplied in the Kit in its place, re-using the original four screws. The shield plate in the aperture plate must face upwards as illustrated to protect the wiring in the head from sunlight that might be focussed into the head by the new front lens assembly.
Figure 3
If you reinstall the original front lens at a later date to return the fixture to standard MAC 250 Wash configuration, you must remove the new aperture plate together with the new front lens assembly.

7. A set of six beam eff ect gobos (P/N 624 20250) is supplied in the Kit. See Figure 6. To install a beam effect gobo, remove a color filter from the color wheel by pressing it gently away from its retaining tabs (A) and lifting it carefully out of the color wheel (B).
8. Filters and gobos have small beads of silicone applied to them to act as cushions. If a bead of silicone from a color filter has become stuck to the color wheel, remove it and replace it on the color filter.
9. Insert gobos with the silicone beads facing the color wheel with reference to Figure 7 and to the illustration on the last page of this guide. Store the original color filters safely for possible future re-use.
Figure 6
10. We recommend that you install beam effect gobos in the color/gobo wheel in the positions seen from the front lens side* shown in Figure 7 in all the fixtures you modify, so that all MAC 250 Beam fixtures will have identical behavior under DMX control. A larger copy of this illustration is included on page 6 of this guide.
*The previous revision of this installation note showed the
color/gobo wheel seen from the lamp side. Figure 7 shows the wheel seen from the front lens side instead to g iv e a true picture of the wheel in reality, because the front lens side is where the color filters/gobos are actually installed. Note that when viewed from the front lens side, the gobo slots are numbered counterclockwise.
11. See Figure 8. The new front lens assembly (P/N
62409076) has a safety cable with a carabiner clip. Attach the clip to the head using either of the two holes (A) provided in the new front lens mounting bracket, then push the clip flat (B) to give space for the front lens assembly.

12. See Figure 9. Clip the new front lens assembly securely onto its mounting bracket in the front of the head.
13. Stick the warning label supplied in the Kit onto the back of the head as shown in Figure 10. With the Beam Kit installed, this label replaces the warning printed on the standard MAC 250 Wash. Do not
illuminate any surface within
3.5m (11ft. 6ins.) of the MAC 250 Beam. Do not
allow the front lens to point at the sun.

14. Finally, before using the fixture, update the fixture software to version 1.4.0 or later, following the software update instructions in the MAC 250 W ash user manual. From software v.1.4.0, the frost filter is moved very slightly forward in orde r to reduce reflections from the CMY flags. Th ere is no need to roll back the software t o an earlier version th an v.1.4.0 if the fixture is returned to a standard MAC 250 Wash configuration at a future time.
The front lens assembly must be unclipped and removed from the head when the fixture is packed in a MAC 250 flightcase. We recommend that you re-use the assembly’s protective packaging supplied in the MAC 250 Beam Kit and store the assembly in the tray in t he flightcase.

Note that when the wheel is viewed from the front lens side, the gobo slots are numbered counterclockwise.
