MAC 550 profile

Side 2
The new MAC 550 was born out of the conscious drive by Martin to consistently improve and innovate; to economize without compromise; and to listen to the needs of the lighting industry. In the MAC 550, the consequence of this energetic pursuit is unprecedented illumination for a 400W fixture, astounding graphics and animation, all wrapped within the award winning design of the MAC 2000. Never before has such speed of effects or head movement been available in a mid-sized fixture. Never before has an array of animation and design possibilities been found outside of the MAC 2000 Series.

Optics

Powerful 400W illumination, enhanced by a multi-layered, dichroic reflector, gives the MAC 550 unprecedented optical efficiency. Advances in lamp technology have allowed a significant and measurable amplification to lumen output, far surpassing the MAC 550s peers.
The MAC 550 features two color wheels, each with eight slots plus open. As with all products in the MAC family, ergonomics and functionality are paramount. In the MAC 550, the color selection may be changed with ease to offer you a seemingly limitless array of color combinations.
Glass, textured glass or metal gobos fit within a six-position rotating gobo wheel, (plus open) and a nine-position static gobo wheel, (plus open). The gobo system permits 16-bit control for extreme accuracy with all gobos easily interchangeable, removing any obstacle to your creativity.

Gobo Animation
The MAC 550 features a DMX controlled gobo animation system - unique to a mid-sized luminare. It is specially engineered to create animated effects such as clouded skies, reflective seas and flames. The system comes complete with one animation wheel, with further wheels available to expand your library. Each wheel is quickly changed via a magnetic coupling without the use of tools.

Dimmer/Shutter

A full range dimmer/shutter is very accurate and allows for smooth color and effect transitions by varying the intensity of the light output. Accelerated strobe effects are possible up to 20 Hz.
Electrical Power Supply Zoom & Focus
The MAC 550s variable motorized zoom and focus expands the beam continuously from 14 - 30 with high precision and sharpness. A switchable power supply covers worldwide voltages and frequencies allowing the fixture to operate anywhere in the world.

Iris & Prism

A bi-directional, 3-facet prism rotates at variable speeds, adding unique effects to gobo projection. The prism can also be replaced giving lighting professionals further options for customization. A motorized iris allows you to resize the beam quickly and accurately for fast effects with smaller beam sizes.

Transportation

The Martin flight case, designed for the MAC family, is recognized in the industry as one of the best purposebuilt cases for the transportation of lighting fixtures. Made of durable ply, it is covered in a tough water-repellent coating for added protection.

Modular design

The design of the MAC 550 is unashamedly inspired by the larger MAC 2000. This award winning design is highly efficient, making service and maintenance easier with fast access to modules and critical components.

Pan/Tilt

New pan and tilt motors give fasterthan-ever movement for a mid-sized fixture, with a pan movement of 540 and a tilt range of 246 The MAC 550 employs an intelligent position correction system that automatically returns the luminare to its original position, should it accidentally be knocked out of place. A multi position, tilt lock mechanism is also featured to permit easy maintenance and handling.

Silence

The MAC 550 contains head and base temperature sensors to ensure that fan speeds are kept to a minimum; bringing noise levels right down to suit theatre and TV studio applications.

Communications

The MAC 550 is DMX512-controllable, equipped with both 3-pin and 5-pin XLR in/out sockets, and totally compatible with coming future standards such as ACN or Ethernet-based protocol.

WARNING! For protection from electric shock, the fixture must be grounded (earthed). The AC power distribution system must be fitted with a fuse or circuit breaker and ground-fault protection. Verify the fixtures power supply setting before applying power.
The MAC 550 Profile is supplied with two main fuses: a 6.3 A fuse (installed) for use with 200-240 Volts AC power. a 10 A fuse (packed with user manual) for use with 100-120 Volts AC power. Install the appropriate fuse in the fuseholder beneath the power switch.

Power supply adjustment

The MAC 550 Profile can operate on 100-120 or 200-240 VAC nominal power at 50/60 Hz. The voltage selection switch is set at the factory for 200-240 V. For use with 100-120 V power, the fixture must be reconfigured as follows.
T o con fig ur e th e po wer su pp ly
1. Disconnect the fixture from AC power. 2. Remove the metal top cover from the front of the base (front is indicated by an arrow on the base). 3. Locate the voltage selection switch. For operation on 200-240 V power, move the switch to the 230V setting. For operation on 100-120 V power, move the switch the to 115V setting. The MAC 550 Profile adapts automatically to 50 or 60 Hz. 4. Replace the base cover. 5. Remove the main fuse holder, which is located beneath the power switch. For operation on 200-240 V power, install the 6.3 A fuse. For operation on 100-120 V power, install the 10 A fuse.

Power connection

Important! Connect the MAC 550 Profile directly to AC power. Do not connect it to a dimmer system; doing so may damage the fixture. You may need to install a plug that fits your supply on the power cable. A 3-prong grounding-type plug must be installed following the manufacturers instructions. The table shows some possible pin identification schemes. If the pins are not clearly identified, or if you have any doubts about proper installation, consult a qualified electrician. To apply power, first verify that the head is unlocked and then set the power switch on the base to the I position.

Table 1: Power plug connections

AC power

Important! Never connect more than 1 data input and 1 data output. The MAC 550 Profile has both 3-pin and 5-pin XLR sockets for DMX input and output. The pin-out on all sockets is pin 1 to shield, pin 2 to cold (-), and pin 3 to hot (+). There is no connection to pins 4 and 5. The sockets are wired in parallel: both inputs connect to both outputs. For reliable data transmission and to avoid damage to the fixture, never use more than one input and one output!

Tips for reliable data transmission
Use shielded twisted-pair cable designed for RS-485 devices: standard microphone cable cannot transmit control data reliably over long runs. 24 AWG cable is suitable for runs up to 300 meters (1000 ft). Heavier gauge cable and/or an amplifier is recommended for longer runs. Never use both outputs to split the link. To split the serial link into branches use a splitter such as the Martin 4-Channel Opto-Isolated RS-485 Splitter/Amplifier. Do not overload the link. Up to 32 devices may be connected on a serial link. Terminate the link by installing a termination plug in the output socket of the last fixture. The termination plug, which is a male XLR plug with a 120 Ohm, 0.25 Watt resistor soldered between pins 2 and 3, soaks up the control signal so it does not reflect and cause interference. If a splitter is used, terminate each branch of the link. Martin fixtures introduced before 1997 have reversed polarity data sockets (pin 2 hot and pin 3 cold). The socket polarity is labelled. Use a phase-reversing cable between the MAC 550 Profile and any Martin device with reversed polarity.

To connect the data link

1. Connect the DMX data output from the controller to the MAC 550 Profiles 3-pin or 5-pin input (male) socket. 2. Using the sockets that match your data cable, connect the output of the fixture closest to the controller to the input of the next fixture. 3. Insert a male 120 XLR termination plug in the 3-pin or 5-pin output of the last fixture on the link.

RIGGING

The MAC 550 Profile can be placed on stage or clamped to truss in any orientation. The mounting points allow the clamp brackets to be fastened parallel or perpendicular to the front as shown Figure 6.
Figure 6: Clamp bracket positions Warning! Always use 2 clamps to rig the fixture. Lock each clamp with both 1/4-turn fasteners. The fasteners are locked only when turned fully clockwise. Attach an approved safety cable to the attachment point labelled SAFETY WIRE in the base. Never use the carrying handles for secondary attachment.

Warning!

To clamp the fixture on a truss
1. Verify that the rigging clamps are undamaged and can bear at least 10 times the weight of the fixture. Verify that the structure can bear at least 10 times the weight of all installed fixtures, clamps, cables, auxiliary equipment, etc. 2. Bolt each clamp securely to a clamp bracket with an M12 bolt (grade 8.8 or better) and lock nut. 3. Align a clamp with 2 mounting points in the base. Insert the fasteners into the base and turn both levers a full 1/4-turn clockwise to lock. Install the second clamp. 4. Block access under the work area. Working safely from a stable platform, hang the fixture on the truss with the arrow towards the area to be illuminated. Tighten the rigging clamps. 5. Install a safety wire that can bear at least 10 times the weight of the fixture. The attachment point is designed to fit a caribiner clamp. 6. Verify that the tilt lock is released. Verify that there are no combustible materials or surfaces to be illuminated within 1 meter of the fixture, and that there are no flammable materials nearby.

The remaining options under display the DMX values received on each channel. If the fixture does not behave as expected, reading the DMX values can help you troubleshoot the problem.

Manual control

The manual control menu () provides commands for resetting the fixture (), turning the lamp on (), and turning the lamp off (). It also permits you to position and move individual effects.

Service utilities

Important! Enter must be held for several seconds to access the utilities menu.

Test sequences

provides a general test of all effects that can be run without a controller. provides
routines for circuit board testing that are for service use only.

Feedback toggles

An on-the-fly position correction system monitors the gobo and color wheels, rotating gobos, and the animation wheel. If a position error is detected, the shutter closes while the effect resets. This feature can be disabled by turning effects feedback ( ) off. The automatic pan/tilt position correction system may be temporarily turned off under . The off setting, however, is not saved and the system will be re-enabled the next time the fixture starts. If the system cannot correct the pan/tilt position within 10 seconds, feedback is automatically disabled.

Calibration

The calibration menu ( ) allows effects to be calibrated. The fixture can be returned to factory calibrated effects and feedback settings using the command ( )

Adjustment

The adjustment menu ( page 37.
) provides manual control for making mechanical adjustments. See

Software upload

The upload mode command ( ) prepares the fixture for a software update. This command is not necessary, however, as upload mode is engaged automatically by the uploader.

EFFECTS

This section describes the functions programmed in the MAC 550 Profile DMX protocols. The fixture has two DMX operating modes, basic and extended. The extended mode requires six more DMX channels than the basic mode and provides all features of the basic mode plus fine control of the dimmer, color wheels, iris, zoom, and focus. Channels references in this section refer to the extended mode protocol unless otherwise noted. The complete DMX protocol begins on page 28.

Lamp power

Lamp-on
The lamp-on command on channel 1 closes the relay that provides power to the lamp. When the lamp is on, the command has no effect. Note: A peak of electric current that can be many times the operating current is drawn for an instant when striking a discharge lamp. Striking many lamps at once may cause a voltage drop large enough to prevent lamps from striking or draw enough current to trip circuit breakers. If sending lamp-on commands to multiple fixtures, program a sequence that strikes lamps one at a time at 5 second intervals.

Lamp-off

The lamp can be doused from the controller with the lamp-off command. The command must be sent for 5 seconds. If the lamp-off command is disabled ( following effects are selected: color wheel 1: slot 1 (DMX 189 - 193) color wheel 2: slot 1 (DMX 189 - 193) prism: in, no rotation (DMX 80 - 89) gobo wheel 1: open (DMX 0 - 11) gobo wheel 2: open (DMX 0 or 194 - 202)
), the lamp-off command works only if the

Fixture reset

If an effect loses its indexing and fails to move to programmed positions, the fixture can be reset from the controller by sending the Reset command on channel 1. If DMX reset is disabled ( ), the reset command can only be executed if the conditions listed under Lamp-off are met. If it is set to , the reset command must be sent for 5 seconds before executing.

Dimming and strobe

The mechanical dimmer/shutter system provides smooth, high-resolution 100 percent dimming, instant open and blackout, random and variable strobe effects, and random and variable pulses in which the dimmer snaps open and slowly dims or snaps closed and slowly opens. Fine control of the dimmer is available in extended mode.

To replace a color filter
Note: Use only genuine MAC 550 color filters. 1. Disconnect the fixture from AC power and allow it to cool. 2. Remove the bottom cover. 3. Turn the color wheel to access the desired filter position. Press the filter forwards slightly to release it and then grasp it by the edges and remove. If your fingers are too large, protect the glass with a piece of paper that has been folded several times and grasp the filter with needle nose pliers. 4. To insert a filter, slide it under the retention spring until it snaps into place. 5. Replace the cover before applying power.

Figure 8: Filter

Gobo wheel 1 provides 6 rotating gobos; gobo wheel 2 provides 9 static gobos. The standard gobo configuration is shown in Figure 9. All gobos are interchangeable with the following limitations: On wheel 1 (rotating), the gobo retention spring works with gobos up to 3 mm in thickness. Thicker gobos can be glued to the holder with a UV adhesive or Loctite 330 Multibond with Activator. On wheel 2 (static), the maximum thickness for gobos is 1.1 mm.
Figure 9: Gobo wheels as seen from front lens

Custom gobos

Martin can provide many additional gobos for the MAC 550 Profile, which accepts the same size gobos as the MAC 500. For more information, please visit the Martin web site at www.martin.com. Custom glass gobos should be made with the artwork reversed on the coated side. This orientation minimizes reflections but is not critical. While glass gobos are generally the most durable, satisfactory results can be obtained at less expense with aluminum gobos. Custom stainless steel gobos can also be used, however they can warp, losing sharpness, in a matter of hours. The useful life will depend on the gobo pattern and the projection cycle. Consult your gobo supplier for more information. For best results, custom gobos should meet the specifications listed on page 42.

Optical configuration

GOBO ORIENTATION IN THE MAC 550 PROFILE
The orientations shown in Figure 10 are correct in most cases, but consult your Martin dealer or gobo supplier if you are in any doubt about the orientation of a specific gobo type.

Coated Glass Gobos

Focus is easiest to maintain if all coated gobos in a fixture are installed with their coatings as close as possible to the same plane of focus. The coated gobos in the MAC 550 Profile are factory-installed in this position. However, if there is an unusually high risk of heat damage on a custom coated gobo, the first priority is normally to ensure that more reflective sides face towards the lamp. If in doubt, install coated gobos with the more reflective (silvered) side towards the lamp, or consult your Martin dealer or gobo supplier. More reflective side towards lamp Less reflective side away from lamp
To minimize the risk of gobo overheating and damage, turn the more reflective side of a coated gobo towards the lamp.
The less reflective side of a coated gobo will absorb less heat if it faces away from the lamp.
To determine which side of a gobo is coated, hold an object up to it. On the uncoated side, there is a space between the object and its reflection and the edge of the gobo can be seen when looking through the glass. Uncoated side Coated side

Textured Glass Gobos

To repl ace rotating gobos
Important! The gobo can fall out if the spring is inserted backwards. 1. Disconnect the fixture from power and allow it to cool. 2. Position the head upside down and remove the bottom head cover. Turn the gobo wheel to the desired position. Grasp the holder by the teeth and pull the holder lightly towards the front lens to release the holder and remove it from the wheel. 3. With a small screwdriver or similar, unhook the end of the gobo spring furthest from the gobo and pull out the spring. Drop the gobo out of the holder. 4. Insert the new gobo in the holder with the side that faces towards the lamp facing upwards, towards the spring (see Figure 10 and Figure 11). 5. Insert the spring with the narrow end against the gobo. To Figure 11: Rotating gobo holder identify the narrow end, press the spring flat: the narrow end is on the inside. Push the end of the spring in under the lip of the holder. 6. Verify that the gobo is seated flush against the holder. Press the spring as flat as possible against the back of the gobo. 7. Work the rim of the gobo holder under both clips and snap the gobo holder back into position. If necessary, a small screwdriver or similar tool may be used to pry the clips away from the wheel. 8. Replace the bottom cover and release the tilt lock before applying power.

ROUTINE

MAINTENANCE
The MAC 550 Profile requires routine cleaning. The schedule depends heavily on the operating environment. It is essential to follow the cleaning guidelines given later in this section. Refer any service operation that is not described here to a qualified Martin technician. Important! Excessive dust, smoke fluid, and particulate buildup degrades performance, causes overheating and will damage the fixture. Damage caused by inadequate maintenance is not covered by the warranty. Warning! Disconnect the fixture from power before removing any cover.

Tilt lock

Important! Release the tilt lock before operating the fixture. The tilt position of the head can be locked for transportation and service with the tilt lock. To lock or unlock the head, pull the lock out and turn it one-quarter turn in either direction.

Cleaning

Regular cleaning is very important for fixture life and performance. Buildup of dust, dirt, smoke particles, fog fluid residues, etc. degrades the fixtures light output and cooling ability. Cleaning schedules for lighting fixtures vary greatly depending on the operating environment. It is therefore impossible to specify precise cleaning intervals for the MAC 550 Profile. Cooling fans suck in airborne dust and smoke particles, and in extreme cases fixtures may require cleaning after surprisingly few hours of operation. Environmental factors that may result in a need for frequent cleaning include: Use of smoke or fog machines. High airflow rates (near air conditioning vents, for example). Presence of cigarette smoke. Airborne dust (from stage effects, building structures and fittings or the natural environment at outdoor events, for example). If one or more of these factors is present, inspect all fixtures within their first 24 hours of operation to see whether cleaning is necessary. Check again at frequent intervals. This procedure will allow you to assess cleaning requirements in your particular situation. Experience and consultation with your Martin service representative will help you determine an appropriate maintenance schedule. Use care when cleaning optical components and work in a clean, well lit area. The coated surfaces are fragile and easily scratched. Do not use solvents that can damage plastic or painted surfaces.

To clean the fixture

1. Disconnect the fixture from power and allow the components to cool completely. 2. Remove the covers, front lens and gobo and dimmer modules as described earlier. 3. Vacuum or gently blow away dust and loose particles with compressed air.
4. Carefully clean the optical components. Remove smoke and other residues with cotton swabs or unscented tissues moistened with isopropyl alcohol. A commercial glass cleaner may be used, but residues must be removed with distilled water. Clean with a slow circular motion from center to edge. Dry with a clean, soft and lint-free cloth or compressed air. Remove stuck particles with an unscented tissue or cotton swab moistened with glass cleaner or distilled water. Do not rub the surface: lift the particles off with a soft repeated press. 5. Remove dust from the head fans and air vents with a soft brush, cotton swab, vacuum, or compressed air. 6. On each side of the head, remove the 2 screws that hold the side covers. Slide the covers forward to remove. Clean the air filters or replace them. If they are saturated with smoke fluid, etcetera, soak them in warm soapy water and blot dry. Position the filters on the side covers and reinstall. See Figure 22. 7. Reassemble the head. 8. Remove the screws from the side cover/grill on the front of the base (front is indicated by an arrow on the bottom). Remove the top cover from the front of the base. Lift the power supply / ballast module up and out to expose the base fans for inspection and cleaning. 9. Reinstall the power supply / ballast module and base cover.

Figure 22: Air filter replacement

Lubrication

The MAC 550 Profile does not require lubrication under normal circumstances. The slides for the zoom and focus lens cars are lubricated with a long-lasting teflon-based grease that can be reapplied by a Martin service partner if necessary.

Lampholder replacement

The lamp holder used in the MAC 550 Profile eventually wears out due to the high voltages that pass through the contacts. Service life will vary, but as a rule you should plan to replace the holder every 4000 hours approximately. Wear begins to show up as discoloration at the contact surfaces. When this happens, resistance increases and the lamp becomes harder to strike. If this process is allowed to continue, the lamp is likely to fail prematurely. Each time the lamp is replaced, inspect the lamp holder and have it replaced by a qualified technician as soon as there are signs of discoloration or pitting at the contact surfaces. Damage caused by failure to replace a worn and/or discolored lamp holder is not covered by the warranty.

Software installation

Software updates are available from the Martin web site and can be installed via the data link with a Martin upload device.
The following are required in order to install software. The MAC 550 Profile update file, available for download from the User Support Area of the Martin website (http://www.martin.com). The Martin Software Uploader program, version 5.0 or later, available for download from the User Support Area of the Martin website.

MESSAGES

Appears when.. the fixture is indexing effects at startup. the fixture has received a reset command from the controller. the effects have been indexed and are moving to their default positions.the lamp access cover is not fully closed. the lamp does not ignite within 30 seconds of receiving the Lamp ON command. Likely reasons are a missing or defective lamp, or insufficient AC voltage. the fixture detects the lamp is ON but no Lamp ON command has been received. This can occur if the lamp relay is stuck or if the lamp-power feedback circuit fails. The fixture may be operated but remote lamp on/off may be affected. What to do Wait for reset to complete. Wait for reset to complete. Set to to prevent accidental reset commands. Wait a few moments. Verify that the lamp access cover is locked in place. Check the lamp. Check that the voltage and frequency settings match the local supply.

(Reset) (Serial reset) (Lamp error)
(Short error) (Base temperature error) (Head temperature error) (Lamp temperature error)
Contact Martin service personnel for assistance.
. there is a fault with the base, head or lamp temperature sensor respectively.
(Lamp temperature cut-out)
. the lamp temperature is too high and thermal protection circuits cut power to the lamp.
Allow fixture to cool. Ensure nothing is obstructing airflow around fixture. Clean air vents, air filters and fans. Reduce ambient temperature. If problem persists, contact Martin service personnel for assistance. Contact Martin service personnel for assistance. Contact Martin service personnel for assistance.

time-out)

. there is a driver/motor malfunction. newly uploaded fixture software also requires updated display software.pan (), tilt () or both () feedback circuits are malfunctioning. It will still be possible to operate the fixture, but it switches into a safe mode where maximum speed is reduced, thus preventing the fixture from losing track of its home position (losing step).
.the electric indexing circuit is malfunctioning. The fixture will, after the time-out, establish a mechanical stop, and continue to work normally.
Reset fixture again. Contact Martin service personnel if problem continues.
(Gobo wheel 2 time-out) (Animation wheel position
.the magnetic-indexing circuit malfunctions (e.g. sensor defective or magnet missing). After the time-out, the effect in question stops in a random position.

TROUBLESHOOTING
Problem Probable cause(s) No power to fixture. One or more of the fixtures is completely dead. Primary fuse blown (located near power inlet). Secondary fuse(s) blown (located on PCBs in base). Bad data link. Data link not terminated. Fixtures reset correctly but respond erratically or not at all to the controller. Incorrect addressing of the fixtures. One of the fixtures is defective and disturbs data transmission on the link. XLR pin-out on fixtures does not match (pins 2 and 3 reversed). Time out error after fixture reset. Mechanical effect loses position. No light and error message displayed. Effect requires mechanical adjustment. Mechanical train requires cleaning, adjustment, or lubrication. Lamp blown Lamp not installed Lamp access safety switch open Remedy Check that power is switched on and cables are plugged in. Disconnect fixture and replace fuse. Disconnect fixture. Check fuses and replace. Inspect connections and cables. Correct poor connections. Repair or replace damaged cables. Insert termination plug in output jack of the last fixture on the link. Check fixture address and protocol settings. Bypass one fixture at a time until normal operation is regained: unplug the XLR in and out connectors and connect them directly together. Have the fixture serviced by a qualified technician. Install a phase-reversing cable between the fixtures or swap pins 2 and 3 in the fixture that behaves erratically. Disable effects feedback (page 14). Contact Martin technician for service. Contact Martin technician for service. Disconnect fixture and replace lamp. Disconnect fixture and install lamp. Verify that lamp access plate is fully seated and locked in place. Allow fixture to cool. Ensure nothing is obstructing airflow around fixture. Clean air vents, air filters and cooling fans.
