LAMP

About the HMI 1200 W/S lamp
The MAC 2000 Profile comes with a double-ended OSRAM HMI 1200 W/S discharge lamp installed. This highly-efficient short-arc source provides an exceptionally stable 6000K color temperature, a color rendering index greater than 90, and an average life of 750 hours.
The lamp is capable of hot restrike. This feature, however, is only supported by the MAC 2000 Profile with electronic ballast.
The ends of the lamp have specially-developed keys, shown in Figure 6, to ensure proper installation. Do not use HMI 1200 W/S lamps with the non-keyed SFc 10-4 base.

Warning!
Installing any other lamp may create a safety hazard or damage the fixture!

The lamp has an average life of 750 hours. To reduce the risk of explosion, replace the lamp before usage exceeds 125% of the average life, i.e., before it exceeds 940 hours. To read lamp hours from the control panel, please refer to “Readouts” on page 15. For optimum performance, avoid turning off the lamp before it has warmed up fully.

Important!
Do not touch the quartz bulb with bare fingers.

Replacement lamps are available from your Martin dealer. Please order Martin P/N 97010304.

The clear quartz bulb must be clean and free of any oils from your fingers. Clean the lamp with an alcohol wipe and polish it with a dry cloth, particularly if you accidentally touch the bulb.

To replace the lamp

Disconnect the fixture from power and allow it to cool. Lock the head horizontally with the top up.
See Figure 4. Release the 4 quarter-turn fasteners marked with arrows on the rear plate. Pull the lamp assembly straight back as far as it goes and let it rest in place.
See Figure 5. Pull the retention spring on the left end up and then swing the end of the lamp out. Pull the other end out of the socket.
See Figure 6. With the nipple on the bulb facing the back, insert the right end of the new lamp in the socket. Pull up on the left spring and snap the other end into place.
Lift the lamp assembly so that lamp is level with the center of the reflector. Push the assembly straight in until it seats, making sure the lamp passes through the reflector opening. Lock the 4 quarter-turn fasteners.
When installing a new lamp, reset the lamp hour and lamp strike counters as described on page 15.

To align the lamp

Switch on the MAC 2000 Profile and allow it to reset. Using either a controller or the control module, turn on the lamp and project an open white beam on a flat surface.
Center the hot spot vertically using the top Allen-head adjustment screw in the center of the rear plate.
If there is significant hot spot, turn the bottom adjustment screw counterclockwise until the light is evenly distributed.
If the light is brighter around the edge than it is in the center, or if light output is low, turn the bottom adjustment screw clockwise until the light is bright and evenly distributed.
Repeat step 2.

AC POWER

Figure 8: Power supply access

Figure 9: Transformer and ballast connections

WARNING!
For protection from electric shock, the fixture must be grounded (earthed). The AC mains supply
shall be fitted with a fuse or circuit breaker and ground-fault protection.

Important!
Verify the power supply settings before applying power.

Power supply settings for magnetic ballast version

In the MAC 2000 Profile with magnetic ballast, both the transformer and the ballast must be tapped correctly for the local AC voltage and frequency. The wrong setting can cause overheating, damage, and poor performance. The factory settings are printed on the serial number label. Note: The 100 and 120 V transformer settings are not used in the magnetic ballast version.

To change the power supply settings

Disconnect the fixture from AC power. Remove the rear base cover as shown in Figure 8.
Find the transformer setting in Table 1. Move the brown wire on the transformer connection block to the position shown in Figure 9.
To expose the ballast connection block, remove the screws from each end of the side plate and tilt it down (Figure 8).
Find the ballast setting in Table 2. Move the brown wire on the ballast connection block to the position shown Figure 9.
Close the base before applying power.

Table 2: Magnetic ballast settings

Power supply settings for electronic ballast version

In the MAC 2000 Profile with electronic ballast, the transformer must be tapped correctly for the local AC voltage. The electronic ballast automatically adapts to the line voltage and frequency. The wrong transformer setting, though, can cause overheating, damage, and poor performance. The factory setting is printed on the serial number label.

FUSES

Electronic ballast models that come factory set for 100 V or 120 V have two 20 A T (time delay) main fuses, which are located near the power switch. Units set at 210 V and above have two 15 A main fuses installed.
If you change the voltage settings, alternate fuses are supplied in bag packed together with this user manual. Use

15 A main fuses when the transformer is set at 208, 230, or 250 V
20 A T fuses when it is set at 100, or 120 V

To change the transformer setting

Figure 10: Transformer connections

Disconnect the fixture from AC power. Remove the rear base cover as shown in Figure 8.
Find the transformer setting in Table 3. Move the brown wire on the transformer connection block to the position shown in Figure 10.
Close the base before applying power.

Table 3: Transformer settings, electronic ballast model

Power connection

Important!
Connect the MAC 2000 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 cord cap that fits your supply on the power cable. A 3-prong grounding-type plug must be installed following the manufacturer’s 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, set the power switch on the base to the “I” position.

Table 4: Cord cap connections

DATA

Important!
Never connect more than 1 data input and 1 data output.

The MAC 2000 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, however, use one input and one output!

Connecting fixtures

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 2000 Profile and any Martin device with reversed polarity.

To connect the data link

Connect the DMX data input from the controller to the MAC 2000 Profile’s 3-pin or 5-pin input (male) socket.
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.
Insert a male 120 Ω XLR termination plug in the 3-pin or 5-pin output of the last fixture on the link.

RIGGING

The MAC 2000 Profile can be placed on stage or clamped to a truss in any orientation. The Fast-Lock system enables quick and easy fastening of the clamp brackets in 4 positions as shown Figure 11.

Figure 11: 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.

Warning!
Attach an approved safety cable to the attachment hole in the base. Never use the carrying handles for secondary attachment.

To clamp the fixture to a truss

Verify that the rigging clamps (not included) 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.
Bolt each clamp securely to a clamp bracket with an M12 bolt (grade 8.8 or better) and lock nut.
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.
If the truss can be lowered, fixtures can be clamped on directly from the double flight case. If the fixture must be lifted, 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.
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.
Verify that the pan and tilt locks are 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.

CONTROL PANEL

The LED control panel is used to set the address and personalities, read lamp hours and other information, calibrate effects, and run a test routine. Most of these functions may be performed remotely via the serial link with the Martin MP-2 Uploader.

Navigation

The DMX address and any messages (see page 34) are displayed when the MAC 2000 Profile is turned on. To enter the menu, press [Menu]. Press [Up] and [Down] to move within the menu. To select a function or submenu, press [Enter].
To escape a function or menu, press [Menu].

Note: [Enter] must be pressed and held for a few seconds to enter the utilities menu.
See Table 6 on page 28 for a complete list of the menu items.

Figure 13: MAC 2000 Profile menu

DMX address and protocol setting
The DMX address, also known as the start channel, is the first channel used to receive instructions from the controller.
For independent control, each fixture must be assigned its own control channels. Two MAC 2000 Profiles may share the same address, however, if identical behavior is desired. Address sharing can be useful for diagnostic purposes and symmetric control, particularly when combined with the inverse pan and tilt options.
Two DMX protocols, 8-bit and 16-bit, are available. The 8-bit mode uses 20 control channels and provides full basic control. The 16-bit mode uses 4 additional channels to provide finer gobo and pan/tilt positioning.

To set the DMX address and protocol

Press [Menu] to enter the main menu.
Press [Up] until AddR is displayed. Press [Enter]. To snap to channel 1, press [Enter] and [Up]. Scroll to
the desired channel and press [Enter].
Select PSET from the main menu and press [Enter]. Select 8bit or 16bt and press [Enter].

Tailoring performance

MOVEMENT

The MAC 2000 Profile provides six options for optimizing movement for different applications.

The protocol setting (PSET)setting selects 8-bit or finer 16-bit control of pan, tilt, and gobo index.
The pan and tilt invert (PATI)menu swaps and/or inverts pan and tilt.
The pan/tilt speed (PTSP) menu provides 3 settings: FAST, NORM, and SLOW. NORM is best for most applications. FAST provides better performance in applications where speed is most important. SLOW provides the smoothest movement and is best in long-throw applications with slow movements through narrow angles.
The studio mode (STUd) setting optimizes all effects besides pan and tilt for speed or quietness.
The shortcuts (SCUT)setting determines whether the color, gobo, and effect wheels always take the shortest path between two static positions or oscillate between outer positions.

TRACKING RESPONSE

The MAC 2000 Profile has a filter algorithm that looks at several position updates in tracking control mode and
calculates the ideal response for smooth movement. Tracking response is adjustable to compensate for variations in controller performance. In most cases the default settings work well.

If tracking mode movement is not satisfactory there are 2 parameters that can be adjusted. The first is selected under
PERS/TRAC/MOdE. The default, MOd1, is the best choice with controllers that calculate intermediate positions at a steady rate. Begin by selecting the alternative, MOd2, which is better if the intermediate positions stray
significantly from the line of travel.

The second parameter is the number of position updates used to calculate speed. The level is adjustable between 1 and 10 under PERS/TRAC/CAL. Increasing the number of samples increases the distance over which speed is calculated, making movement smoother but less responsive to sudden changes. Experiment for best results.

DISPLAY
The display intensity (dINT) setting controls display brightness. The display on/off setting (dISP) determines
whether the display remains on or extinguishes two minutes after the last key- press. To flip the display, press [Up] and [Down] simultaneously.

LAMP

There are two settings that modify lamp control: Automatic Lamp On (ALON) and DMX Lamp Off (DLoF).

When ALON is off, the lamp remains off until a “lamp on” command is received from the controller. When ALON is
on, the lamp strikes automatically after the fixture is powered on. When ALON is set to DMX, the lamp strikes
automatically when the fixture receives DMX data, and it extinguishes 15 minutes after DMX data is lost.

When ALON is set to either ON or DMX, the automatic lamp strike timing is staggered to prevent all lamps from
striking at once. The delay is determined by the fixture address.

If striking lamps from the controller, note that striking many lamps at once may cause a voltage drop large enough to
prevent lamps from striking or trip the main circuit breaker. Avoid this by programming a “lamp on” sequence that
strikes lamps one at a time at 5 second intervals.

Power to the lamp can be turned off from the controller if DMX Lamp Off (dLOF) is on. If dLOF is off, a DMX lamp off command is executed only if position 7 is selected on the color wheel and gobo 5 is selected on both gobo
wheels. Be careful: with the magnetic ballast model, it is not possible to restrike the lamp until it has cooled for a few
minutes. (The electronic ballast model provides hot restrike.)

DMX RESET
The fixture can be reset from the controller if DMX reset (PERS/dRES) is ON. If DMX reset is OFF, the reset
command can only be executed if position 7 is selected on the color wheel and gobo 5 is selected on both gobo wheels.

CUSTOM SETTINGS
The custom configuration function allows you to save and recall three sets of fixture settings. The savable settings are
DMX mode, pan/tilt speed, pan/tilt inverse and swap, DMX lamp off and reset, display settings, shortcuts, studio
mode, automatic lamp on, effects feedback, tracking algorithm, and tracking samples.

Readouts

Note: The MP-2 Uploader provides commands to display the time, temperature, and version readouts on the fixture control panel.

TIME
INFO/TIME provides readouts of fixture hours (HRS), lamp hours (L HR), and lamp strikes (L ST). Under
each item is a resettable (RSET) increment counter and a non-resettable counter for total accumulated hours/strikes
since fabrication (TOTL). To reset an increment counter, display it and then press [Up] until it reads 0. (This may also be done remotely using the MP-2 Uploader.)

TEMPERATURE
INFO/TEMP provides readouts of the head and base temperature in Celsius and Fahrenheit.

FIRMWARE VERSION
INFO/VER displays the version number of the installed firmware. The firmware version is also displayed briefly at
startup.

DMX
The DMXL menu shows the DMX start code (STCO) and DMX values received for each effect.

Service messages

The Service LED on the control panel lights under conditions that require fixture service, and there is a message
describing the service required. To display the message, select SMSG in the main menu. This item is available only when the LED is lit. There are two service messages.

Replace lamp is displayed when the lamp counter exceeds 750 hours, which is the rated average life for the HMI 1200 W/S lamp. The maximum service life is 125% of the average life, or 940 hours.

Fixture overheating is displayed when the head temperature exceeds 120° C (248° F). Overheating is
likely due to dirty air filters, fans, or air vents; incorrect power supply settings, or a defective fan.

Service utilities

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

TEST SEQUENCES
TSEQ provides a general test of all effects that can be run without a controller. UTIL/PCBt provides routines for circuit board testing that are for service use only.

FEEDBACK TO GGLES
An on-the-fly position correction system monitors the color wheel, gobo wheels, gobos, rotating effects, and effect
wheel. If a position error is detected, the shutter closes while the effect resets. This feature can be disabled by turning effects feedback (UTIL/EFFb) off.

The automatic pan/tilt position correction system may be temporarily turned off under UTIL/FEbA. 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.

ADJUSTMENT
The adjustment menu (UTIL/Adj) provides manual control for making mechanical adjustments. See page 33.

CALIBRATION
The calibration menu (UTIL/CAL) provides utilities to define offsets in software that are relative to the mechanical reset or home positions. This allows you to fine tune optical alignment and achieve uniform performance between fixtures. Dimmer and zoom are calibrated to defined points. The other effects are calibrated relative to an
arbitrary reference fixture.
Default offset settings may be restored by selecting default offsets (UTIL/dFOF).

To calibrate effects

Apply power but do not strike the lamp until zoom has been calibrated.
To calibrate zoom, first remove the bottom head cover. Select UTIL/CAL/ZOOF and press [Enter]. Adjust the offset until the face of the zoom lens plate is flush with the back edge of the focus plate (Figure 14). Press [Enter] to save the setting. Replace the bottom head cover.
Figure 14: Zoom calibration point
Pan calibration is most useful when multiple fixtures are stacked vertically. To calibrate, set zoom, focus, iris, and tilt position for easy one-over-the-other comparison and set each fixture to the same pan DMX value. Select one fixture to be the reference fixture. On the other fixtures, select UTIL/CAL/P OF and press [Enter]. Adjust the offset as necessary to align the beam with the reference beam. Press [Enter] to save the setting.
Tilt calibration is most useful when multiple fixtures are arranged horizontally. To calibrate, set zoom, focus, iris, and pan position for easy side-by-side comparison and set each fixture to the same tilt DMX value. Select one fixture to be the reference fixture. On the other fixtures, select UTIL/CAL/T OF and press [Enter]. Adjust the offset as necessary to align the beam with the reference beam. Press [Enter] to save the setting.
To calibrate the dimmer, select UTIL/CAL/D OF and press [Enter]. Hold a piece of paper over the lens. Set the offset to 0 and then increase it until light is clearly projected onto the paper. Press [Enter] to save the setting. Remove the paper.
To calibrate color mixing flags (cyan, magenta, yellow, and color temperature correction), project white beams with no dimming and position them for easy comparison. On each fixture, including the reference, select UTIL/CAL/C OF and press [Enter]. (This adds a defined amount of cyan.) Select one fixture to be the reference. Adjust the offsets on the other fixtures to match the reference color. Press [Enter] to save the setting. Repeat for M OF (magenta), Y OF (yellow), and CTOF (CTC).
Focus calibration is useful when two or more fixtures are the same distance from a projection surface. To calibrate focus, set up all fixtures with the same focus, zoom, dimming, iris, and gobo values. Select a focussed fixture to be the reference. On the other fixtures, select UTIL/CAL/FOOF and press [Enter]. Adjust the offset to focus the image. Press [Enter] to save the setting.

SOFTWARE UPLOAD
The software update mode is normally engaged automatically by the upload device.

OPTICAL CONFIGURATION

Figure 19: Replacing rotating effects

EFFECTS

The MAC 2000 Profile is compatible with USITT DMX512 controllers. The fixture has two DMX operating modes, 8-bit and 16-bit.16-bit mode requires four more DMX channels than 8-bit mode but provides more precise gobo indexing and pan/tilt positioning. All other functions are identical. The complete DMX protocol begins on page 24.

Dimming and strobe
The mechanical dimmer/shutter system provides smooth, high-resolution 100 percent dimming, instant open and
blackout, random and variable strobe effects up to 10 Hz, and random and variable pulses in which the dimmer snaps open and slowly dims or snaps closed and slowly opens.

Color mixing
The color mixing system uses continuous dichroic cyan, magenta, and yellow (CMY) color filters. It is a subtractive system that removes color from white light. Inserting all three filters results in loss of light: for maximum brightness, mix 2 colors at a time.

Color temperature correction
The color temperature correction (CTC) system uses a continuous 0 – 178 mireds color filter that lowers the color temperature from 6000 K to 2900 K.

Random color mixing
Variable speed random color mixing using the CMY filters may be selected at the top of channel 7. When selected, channels 3 – 5 set the maximum or minimum amount of each color in the mix. Values up to 127 set a minimum
amount: the color is randomly inserted from the selected value up to 100%. Values over 127 set a maximum amount: the color is inserted from 0% up to the selected value. To use the full range of a color in the random mix, select a
minimum value of 0% or a maximum value of 100%. To exclude a color from the random mix, select a maximum value of 0%.

Fixed colors and gobos
The color/gobo wheel provides seven slots with four dichroic color filters and three glass gobos. To change the color or gobo, see “To replace color filters or gobos” on page 19.
The wheel can be scrolled, allowing for split color effects, snapped to fixed positions, and continuously rotated in both directions at different speeds. When the effects speed channel is set from 252 to 255, the dimmer automatically closes while the color wheel is moving between static positions.

Gobos

Two overlapping gobo wheels provide room for 10 glass gobos. See page 17 to change gobos.
Gobos may be rotated and shaken at varying speeds and indexed to any position. Extremely accurate positioning is available in 16-bit mode.
For each wheel, the gobo and type of rotation (indexed or continuous, with or without shake) are selected on the
wheel’s Gobo & Function Channel, which also provide commands for continuous wheel rotation. The gobo position
index and rotation speed are selected on its Position/Velocity Channel. In 16-bit mode, the position is further adjusted on the wheel’s Fine Position Channel.

Effect wheel

The effect wheel provides a variable frost filter and two rotating slots that house a beam shaper and a three-facet prism.
The position and velocity of the rotating slots are selected on the effect wheel’s Position / Velocity Channel.
The effect wheel channel also provides eight preprogrammed effect combinations.

Iris

The iris closes down to 15 percent of its full-open diameter with high, 200-step resolution. The Iris Channel also provides random and variable speed pulsating iris effects.

Focus and zoom
The focus lens focusses the beam from approximately 2 meters (6.5 feet) to infinity. The zoom lens widens the beam from approximately 10° at full spot to 28° at full flood.

Pan and tilt

The yoke pans 540° and the head tilts 267°. For maximum positioning accuracy, select 16-bit mode.
The pan/tilt speed (fast, norm, or slow) may be selected on the pan/tilt speed channel. Setting the pan/tilt speed channel to “blackout” causes the shutter to black out the light while the head is moving.

Speed control

There are two ways to control the speed at which effects move from one static position to another. These are known as tracking control and vector control and are selected on the Pan/Tilt Speed and Effect Speed Channels. These channels are independent so you may, for example, combine a vector control pan movement with a tracking control color fade.

In tracking mode, speed is determined by the cross-fade time. The controller continuously sends small position
changes that the fixture “tracks.” To enable tracking mode, set the relevant speed channel to a tracking value. Note that in addition to enabling tracking control, some tracking values also provide overrides of the menu settings.

In vector mode, speed is set directly on a speed channel. The cross-fade time must be 0. Vector control provides a way to set speed on controllers that do not have programmable fade times and results in smooth movement regardless of the cross-fade time or the controller’s processing power.

To open the iris slowly in tracking mode, for example, you program a scene with the iris fully closed and a second
scene with the iris fully open. Then you set a cross-fade time between the two scenes of, say, 10 seconds. The controller gradually changes the iris position value from 199 (closed) to 0 (open).

To open the iris slowly in vector mode, you program the iris closed and open as before. Then you set the cross-fade time to 0 and program a slow speed, in the second scene, on the Effect Speed Channel.

ROUTINE MAINTENANCE

The MAC 2000 Profile requires routine cleaning. The schedule depends heavily on the operating environment; please consult a Martin service technician for recommendations.
Refer all service not described here to a qualified Martin technician.

Important!
Excessive dust, smoke fluid, and particulate buildup degrades performance and causes overheating and damage to the fixture that is not covered by the warranty.

Warning!
Disconnect the fixture from power before removing any cover.

Cleaning

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.
Inspect the air filters regularly and clean before they become clogged. Replace the air filters with new ones when replacing the lamp.
To maintain adequate cooling, dust must be cleaned from the fans and air vents periodically.

To clean optical components

Disconnect the fixture from power and allow the components to cool completely. Remove the head cover.
Vacuum or gently blow away dust and loose particles with 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.
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.

To clean the fan and air vents

Remove dust from the fans and air vents with a soft brush, cotton swab, vacuum, or compressed air

To clean or replace the air filters

Disconnect the fixture from power. On each side of the head, remove the 2 screws that hold the side cover using a Torx-20 screwdriver. Slide the cover forward to remove. Lift the filter off of the cover.
Clean the filters with a vacuum or compressed air, or replace them. If they are saturated with smoke fluid, etcetera, soak them in warm soapy water and blot dry.
Place the filters on the covers and replace the covers.
