LAMP SAFETY
• Prolonged exposure to an unshielded discharge lamp can cause eye and skin burns. Do not stare directly into the light output. Never look at an exposed lamp while it is lit.
• Do not operate the fixture with missing or damaged covers, shields, lenses or ultraviolet screens.
• A hot discharge lamp is under pressure and can explode without warning. Allow the fixture to cool for at least 2 hours 45 minutes and protect yourself with safety glasses and gloves before handling a lamp or servicing the fixture internals.
• Replace the lamp immediately if it becomes visually deformed, damaged or in any way defective
• Monitor hours of lamp use and lamp intensity and replace the lamp when it reaches the limit of its service life as specified in this manual or by the lamp manufacturer.
• Install only an approved lamp.
• If the quartz envelope of a discharge lamp is broken, the lamp releases a small quantity of mercury and other toxic gases. If a discharge lamp explodes in a confined area, evacuate the area and ventilate it thoroughly. Wear nitrite gloves when handling a broken discharge lamp. Treat broken or used discharge lamps as hazardous waste and send to a specialist for disposal.
PROTECTION FROM BURNS AND FIRE
• The exterior of the fixture becomes very hot – up to 170° C (338° F) – during use. Avoid contact by persons and materials. Allow the fixture to cool for at least 2 hours 45 minutes before handling.
• Keep all combustible materials (e.g. fabric, wood, paper) at least 0.2 m (8 in.) away from the fixture. Keep flammable materials well away from the fixture.
• Provide a minimum clearance of 0.1 m (4 in.) around fans and air vents.
• Do not illuminate surfaces within 2.5 m (100 in.) of the fixture.
• Position or shade the head so that the lens does not face the sun at any time during daylight hours. The lens can focus the sun's rays inside the fixture, creating a potential fire hazard.
• Do not operate the fixture if the ambient temperature (Ta) exceeds 40° C (104° F).
• Do not modify the fixture in any way not described in this manual or install other than genuine Martin parts. Do not stick filters, masks or other materials onto any lens or other optical component. Use only Martin-approved accessories to mask or modify the light beam.
• Do not attempt to bypass a thermostatic switch or fuse. Replace defective fuses with ones of the specified type and rating only.
PROTECTION FROM INJURY DUE TO FALLS
• Do not lift or carry the fixture alone.
• Use two evenly spaced clamps to suspend the fixture from rigging structures. Do not use only one clamp.
• When clamping the fixture to a truss or other supporting structure at any other angle than with the yoke hanging vertically downwards, use two half-coupler clamps. Do not use G-clamps, quick-trigger clamps or any other type of clamp that does not completely encircle the supporting structure when fastened.
• When suspending the fixture, ensure that the supporting structure and all hardware used can hold at least 10 times the weight of all devices suspended from them.
• Do not use the handles in the base or the handles on the top of the yoke for hoisting or secondary attachment.
• Install as described in this manual a secondary attachment such as a safety cable that is approved by an official body such as TÜV as a safety attachment for the weight of all the fixtures it secures. The safety cable must comply with EN 60598-2-17 Section 17.6.6 and be capable of bearing a static suspended load ten times the weight of the fixture.
• Check that all external covers and rigging hardware are securely fastened.
• Block access below the work area and work from a stable platform whenever installing, servicing or moving the fixture.

AC power

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

Power input and primary fuses

The MAC III AirFX features an auto-sensing switch-mode power supply that automatically adapts to 200-240 V (nominal) AC power at 50 or 60 Hz. It is protected by two 16 A slow-blow primary fuses, one for the live conductor and one for the neutral conductor.
To install fuses:
1. Disconnect the fixture from
AC power.
2. Use a flat-headed
screwdriver to open the two main fuseholders, located above the power on/off switch and mains input socket.
3. Install one 16 AT fuse in
each fuseholder.
4. Reinstall the fuseholders
before reapplying power.

Power connection

Important! Connect the MAC III AirFX
directly to AC power. Do not connect it to a dimmer system; doing so may damage the fixture.
The MAC III AirFX requires a power input cable with a Neutrik PowerCon NAC3FCA cable connector for AC mains power input. The cable must meet the requirements listed under “Protection from electric shock” on page 5.
Martin™ can supply either a suitable 3 m (9.8 ft.) power cable with PowerCon input connector installed or the PowerCon input connector without a cable (see “Accessories” on page 59).
If you need to install a PowerCon connector on the power cable, see the next section.

Lamp

About the discharge lamp

The MAC III AirFX is designed for use with an Osram Lok-it HTI 1500W/60/P50 - 7mm lamp. This highly efficient single-ended discharge source provides a color temperature of 6000 K, a color rendering index greater than 90, an average service life of 750 hours and semi-hot restrike, meaning that a hot lamp is ready to strike again after 90 seconds.
Lamp power is automatically reduced to approximately 800 W after 10 seconds when the fixture is blacked out in order to reduce cooling fan activity and power consumption. The lamp returns to 1500 W as soon as the dimmer and/or shutter are opened.
Warning! Installing any other lamp may create a safety hazard or damage the fixture!
To reduce the risk of explosion, replace the lamp when it reaches the limit of its average service life, i.e. when usage reaches 750 hours. Never exceed the lamp’s average service life by more than 10%. To read lamp hours in the fixture’s display, refer to the section on lamp hours readouts on page 19. Replace the lamp immediately if it is deformed or in any way defective.
For maximum service life, avoid powering the lamp off until it has warmed up for at least 5 minutes.

Warning! Wear safety glasses and gloves when handling lamps. The clear lamp bulb is integral with the ceramic lamp base. Do not try to separate the bulb from the base.
Important! The lamp can be a stiff fit in its holder. Twist the lamp base a full 45° clockwise when installing to ensure that the lamp contacts are fully engaged.
Replacement lamps are available from your Martin dealer requesting P/N 97010348. The clear bulb must be perfectly clean. Do not touch it with your fingers. Clean the lamp with an alcohol
wipe and polish it with a dry cloth before installing, particularly if you accidentally touch the bulb. To replace the lamp:
1. Disconnect the fixture from power and allow it to cool for at
least 2 hours 45 minutes.
2. Lock the head.
3. Release the screw on the lamp access cover and open the
cover.
4. Grasp the ceramic lamp base, twist it 45° counterclockwise
and withdraw the lamp from the fixture as shown in Figure 2.
5. The lamp base has two metal contacts, one narrow and one
wide, that fit into corresponding narrow and wide slots in the lampholder. Line up the contacts on the replacement lamp’s base with the corresponding slots in the lampholder, slide the lamp into the fixture so that the contacts are fully engaged in the slots, and then twist the lamp base a full 45° clockwise until it locks into position with a noticeable click. The lamp is a stiff fit and trying to strike a lamp that is not correctly installed can cause damage that is not covered by the product warranty, so ensure that the lamp is correctly locked into position.
6. Close the lamp access cover and tighten the screw to
secure the cover before reapplying power.
7. After installing a new lamp, reset the lamp hour counter (see
the section on lamp hours readouts on page 19).

Lamp adjustment

Warning! Adjust the lamp with the fixture cool. The fixture may become hot during adjustment, so wear heat-resistant safety gloves.
As well as being undesirable for aesthetic reasons, a significant hot-spot in the beam will focus extra heat onto optical components and may cause damage that is not covered by the product warranty.
After fitting a new lamp, adjustment may be required to obtain an even beam. To adjust the lamp:
1. If the fixture has been in use, allow it to cool for at least 2 hours 45 minutes to avoid the danger of burns,
and wear heat-resistant safety gloves.
2. Apply power, allow the fixture to reset, then set
zoom to narrow, turn on the lamp and open the mechanical shutter.
3. Aim the fixture at an even surface and make
sure no further commands can be sent by DMX.
4. See Figure 3. Screw the three lamp adjustment
screws in or out to obtain the most even beam.

DMX data link

The MAC III AirFX has 5-pin locking XLR sockets for DMX and RDM input and output. The default pin-out on both sockets is:
• pin 1 to shield
Port 1, DMX and RDM communication:
• pin 2 to data 1 cold (-)
• pin 3 to data 1 hot (+)
Port 2, not used by default but available for data communication:
• pin 4 to data 2 cold (-)
• pin 5 to data 2 hot (+).
The default use of Port 1 for DMX and RDM can be altered in the control panel (see “Personality – tailoring performance” on page 17).

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.
• 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.
• Install a DMX termination plug on the last fixture on the link.
To connect the data link
1. Connect the DMX data output from the controller to the MAC III AirFX’s data input (male XLR) socket.
2. Run the data link from the MAC III AirFX’s data output (female XLR) socket to the data input of the next
fixture.
3. Terminate the data link by connecting a 120 Ohm, 0.25 Watt resistor between the data 1 hot (+) and cold
(-) conductors (and between data 2 hot and cold if used) at the data output of the last fixture on the link. If a splitter is used, terminate each branch of the link.

Physical installation

Warning! The MAC III AirFX has a powerful pan motor. The torque reaction when the head is panned suddenly can cause the base to move if the fixture is standing unsecured on a surface. Do not apply power to the MAC III AirFX unless the base is securely fastened to a surface or to rigging hardware.
Warning! Use 2 clamps to rig the fixture. Do not hang the fixture from only one clamp. Lock each clamp with both 1/4-turn fasteners. Fasteners are locked only when turned fully clockwise.
Warning! When suspending the fixture above ground level, secure it against failure of primary attachments by attaching a safety wire that is approved as a safety attachment for the weight of the fixture to the attachment point in the base. Do not use the carrying handles for secondary attachment.
Warning! When clamping the fixture to a truss or other structure at any other angle than with the yoke hanging vertically downwards, use two clamps of half-coupler type. Do not use any type of clamp that does not completely encircle the structure when fastened.
Warning! Position or shade the head so that the lens does not face the sun at any time, even for a few seconds, during daylight hours. The MAC III AirFX’s lens can focus the sun's rays inside the fixture, creating a potential fire hazard and causing internal damage.
Important! Do not point the output from other lighting fixtures at the MAC III AirFX from a distance of less than 3 m (10 ft.), as intense illumination can damage the display.
The MAC III AirFX can be fastened to a surface such as a stage or clamped to a truss in any orientation. Clamps must be half-coupler type (see Figure 5) unless the fixture is installed with the yoke hanging vertically downwards. The mounting points allow the clamp brackets to be fastened parallel, perpendicular or at 45° to the front, as shown Figure 4.
Pan and tilt range can be limited via the control panel to allow fixtures to be installed close to each other or to obstacles with no risk of collision (see
PAN/TILT SETTINGS on page 17).
Clamping the fixture on a truss
1. Check that the rigging clamps are
undamaged and can bear at least 10 times the weight of the fixture. Check that the structure can bear at least 10 times the weight of all installed fixtures, clamps, cables, auxiliary equipment, etc.
Figure 4: Clamp bracket positions
Physical installation 13
Page 14
2. Bolt each clamp securely to a
clamp bracket with an M12 bolt (minimum grade 8.8) and lock nut.
3. See Figure 6. Note the position of
the arrows on the bottom of the base that indicate the front of the fixture.
Half-coupler Omega clamp

Figure 5: Martin rigging hardware
Figure 6: Front of fixture
4. Align a clamp with 2 mounting points in the base. See
Figure 7. Insert the fasteners into the base and turn both levers a full 90° clockwise to lock. Install the second clamp.
5. Block access under the work area. Working from a stable
platform, hang the fixture on the truss with the arrows marked FRONT printed on the base of the fixture facing towards the area to be illuminated. Tighten the rigging clamps.
6. See Figure 8. Install a safety wire that is approved as a
safety attachment for the weight of the fixture by looping it through the safety attachment wheel on the bottom of the base.
7. Check that the tilt lock is released. Check that there are no
combustible materials within 0.2 m (8 in.) or surfaces to be illuminated within 2.5 m (100 in.) of the fixture, and that there are no flammable materials nearby.
8. Check that there is no possibility of heads or yokes colliding
with other fixtures. Note that pan and tilt range on the MAC III AirFX can be restricted by setting minimum and maximum limits via the control menus. This feature allows fixtures to be installed closer together or closer to obstacles.
9. Check that other lighting fixtures cannot project light at the
MAC III AirFX from a distance of less than 3 m (10 ft.), as intense illumination can damage the MAC III AirFX’s display.

Control panel operations

You can configure individual fixture settings such as the MAC III AirFX’s DMX address, read out data, execute service and view the event log using the fixture’s backlit graphic display and control panel. The control menu overview starting on page 48 gives a complete list in table form of the menus and commands available.
C
A
Figure 9: Display and control panel
B
After a pause while the fixture boots and resets, the DMX address and any status messages (see page 53) appear in the graphic display A when the MAC III AirFX is powered on.

Using the control panel

Click (i.e. press once) the jog wheel B once to enter the menus. Rotate the jog wheel to scroll up and down menus and click the jog wheel once to make a selection. Rotating the jog wheel faster gives high-speed scrolling.
Once you have made a selection, either click the jog wheel to save it or press the Escape button C to cancel. If you save the selection, Saving... is displayed for 1 second. If you cancel, the menu returns to the previously saved value. Press the Escape button to step backwards through the menus.
The jog wheel and Escape button continue to function while the Saving... message is displayed.

Status LED on jog wheel

An LED in the center of the jog wheel indicates fixture status depending on the color displayed and DMX status depending on whether the LED flashes or lights constantly:
GREEN: All fixture parameters normal.
AMBER: Warning active (service interval exceeded, for example). If ERROR MODE is set to Normal, the warning message will be shown in display. If ERROR MODE is set to Silent, the display must be activated with the jog wheel to display the warning message.
RED: Error detected. If ERROR MODE is set to Normal, the error message will be shown in display. If ERROR MODE is set to Silent, the display must be activated with the jog wheel to display the error message.
FLASHING: No DMX signal detected.
LIGHTS CONSTANTLY: Valid DMX signal detected.
If an error has been detected and the LED is red when the fixture is powered off, the LED will continue to flash red slowly. This feature allows easy identification of fixtures that require service intervention even if fixtures are disconnected from power.
Martin flightcases for the MAC III AirFX contain a small window through which the status LED is visible.
Control panel operations 15
Page 16

Battery power

The display and control panel are powered by the MAC III AirFX’s onboard battery. This gives access to the most important functions in the control panel – including DMX addressing – when the fixture is not connected to AC power.
To activate the display when the fixture is not connected to power, press the Escape button. The display extinguishes after 10 seconds with no jog wheel activity and the control panel is de-activated after 1 minute with no jog wheel activity. Press the Escape button again to re-activate.

Mains power indicator

When the fixture is connected to AC mains power, a ‘battery recharging’ icon appears in the display. When the battery is fully charged, the battery icon is replaced a mains plug icon.

Status indicators in display

The status indicators on the right of the display have the following functions:
LAMP lights green when the lamp is powered.
ETHERNET lights green when the MAC III AirFX is correctly connected to an Ethernet network (at the moment there is no provision for direct connection to Ethernet).
DMX lights green when the MAC III AirFX is receiving a valid DMX signal.
PAN /T ILT lights yellow when pan/tilt limits have been activated (see page 17) and lights orange when Followspot mode is enabled (see “Followspot mode” on page 25).

Shortcuts pop-up

If you hold the Escape button pressed in for 2 - 3 seconds, a pop-up window with shortcuts to important commands appears. Select a command and click the jog wheel to activate, or press Escape to cancel.
RESET resets the whole fixture
LAMP ON/OFF strikes or douses the lamp.
ROTATE DISPLAY rotates the MAC III AirFX display.
FOLLOWSPOT MODE calls up the followspot menu.
EVENT LOG calls up the event log menu.

Settings stored permanently

The following settings are stored permanently in the fixture memory and are not affected by powering the MAC III AirFX off and on or by updating the fixture software:
• DMX address
• Fixture ID
• All personality settings (pan/tilt and pan/tilt limit, linked zoom/focus, lamp cooling, fan clean mode, dimming curve, DMX lamp off, DMX reset, parameter shortcuts, all display settings, error mode)
• Factory settings
• Fixture info (resettable power-on, lamp-on, lamp strikes, and air filter counters)
• All Service settings (adjust, calibration, firmware)
These settings can be returned to factory defaults using the control menus or via DMX.

DMX address

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. If you give two MAC III AirFXs the same address, they will behave identically. Address sharing can be useful for diagnostic purposes and symmetrical control, particularly when combined with the inverse pan and tilt options.
DMX addressing is limited to make it impossible to set the DMX address so high that you are left without enough control channels for the fixture in the 512 channels available in one DMX universe.
DMX address setting
To set the fixture’s DMX address:
16 MAC III AirFX user manual
Page 17
1. Press the jog wheel to enter the main menu.
2. Rotate the jog wheel to scroll down to DMX ADDRESS, then click the jog button. Rotate the jog wheel to
scroll to the desired address and click the jog button to save.
3. Press the Escape button to step back to the main menu.

Fixture ID

The MAC III AirFX lets you set a four-digit ID number to ease identification of the fixtures in an installation. When a fixture is powered on for the first time, it displays its DMX address by default. As soon as you set an ID number other than 0000 in FIXTURE ID, the MAC III AirFX will display this ID number by default.
To let you distinguish easily between ID numbers and DMX addresses, the ID number is always displayed with four digits and DMX address is displayed with between one and three digits.
Personality – tailoring performance
The MAC III AirFX provides several options that let you optimize the fixture for different applications in the PERSONALITY menu:
• The PAN/TILT SETTINGS menu gives three options:
- PAN/TILT CONTROL lets you swap and/or invert pan and tilt and activate the pan and tilt limits you
define in PAN & TILT LIMIT SETTINGS (see below).
- MOVE ON RESET lets you choose if you want pan and tilt to move when the fixture resets or not. Pan
and tilt movement can be a useful visual sign that fixtures in a rig are powering up and resetting.
- PAN & TILT LIMIT SETTINGS lets you define minimum and maximum limits for both pan and tilt
angles, making it possible to install fixtures close to obstacles such as other fixtures with no risk of collision. Settings are based on the following principles:
Pan range for pan limit purposes runs from 0° to 360° clockwise as seen looking at the fixture from the bottom of the base towards the yoke, as if the fixture was hanging downwards underneath you.
Tilt range is +134° and -134° either side of 0°, which is the head straight up position with the front glass pointed directly away from the base.
The light beam points fully forward (the front of the fixture is indicated by the arrows printed under the base) when pan is set to 90° or 450° and tilt is set to +90°.
Selecting Inside keeps pan and tilt inside the limits you set – i.e. angles define a ‘safe zone’. Selecting Outside keeps pan and tilt outside the limits you set – i.e. angles define a ‘no-go zone’. Limits are not activated until the head is panned and tilted into its safe zone or out of its no-go zone. When pan/tilt limits are active, the PAN/TILT light at the bottom right of the display lights yellow.
See Figure 10. To limit pan so that it stays inside a safe zone 20° either side of fully forward and limit tilt so that it stays inside a safe zone 18° either side of fully forward, for example:
1. Set PAN MINIMUM to 70°.
2. Set PAN MAXIMUM to 110°.
3. Set TILT MINIMUM to +72°.
4. Set TILT MAXIMUM to +108°.
5. Set P/T LIMIT AREA to Inside.

Control panel operations 17
Page 18
Important! Regardless of the pan and tilt limits you set, when you power the fixture off, the head will sink under
gravity to the nearest rest position (e.g. with the lens pointing vertically downwards if the fixture is hanging in a rig, or to one side if the fixture is standing fastened to a horizontal surface). When you power the fixture on, the head will not move until the fixture receives a pan or tilt command. When a command is received, if the head’s rest position is outside its pan/tilt limits, the head will move slowly until it is within its limits. This feature reduces the risk of damage caused by a collision.
Pan and tilt limits can quickly be returned to the factory default setting (all limits at 0°, pan/tilt limits disabled) by setting DEFAULT LIMIT SETTINGS to On and clicking with the jog wheel to confirm.
SPEED SETTINGS lets you set PAN & TILT SPEED to Normal, Fast (optimized for speed) or Slow (optimized for smooth movement – useful in long-throw applications). Likewise, you can set EFFECT SPEED to Normal, Fast or Slow. You can also set effect speed to Follow P/T speed, in which effects will always use whatever speed is set for pan and tilt.
The FANS menu gives three cooling fan options:
- LAMP COOLING sets the lamp cooling effect to 50% or 80%. The color temperature of the lamp and
lamp performance towards the end of the lamp life vary slightly with the level of lamp cooling applied. The default level is 80%, which is recommended for optimum performance over the full life of the lamp. Setting to 50% gives a slightly lower color temperature and quieter fan operation but accelerates the gradual reduction in output which is normal over the lifetime of a discharge lamp.
- FAN CLEAN gives three options for automatically clearing dirt from fans:
Off sets fans to normal operation with no fan cleaning function. Auto sets fans to normal operation, but if a fan error is detected, the fan that has reported an error
speeds up to 100% for a short period and then returns to normal operation. If the fan error is still detected after three attempts at cleaning, the fan returns to normal operation but continues to report a fan error. This feature works independently for each of the fans. Attempts at cleaning are reset to zero if the fixture is reset or if FAN CLEAN MODE is updated.
Forced sets all fans to 100% speed until another FAN CLEAN MODE setting is selected.
This feature does not eliminate the need to inspect and clean cooling fans at regular intervals (see “Cleaning” on page 37).
- FAN MODE allows you to set fans to Always on or Follow lamp off mode, in which fan operation is
disabled when the lamp is powered off.
DIMMING CURVE provides four dimming options (see Figure 11):
Output
Output
Output
Output
DMX % DMX % DMX % DMX %
Optically linear VRMS linear Square law Inverse square law
Figure 11: Dimming curve options
- Optically linear – the increase in light intensity appears to be linear as DMX value is increased.
- VRMS linear (S-curve) – light intensity control is finer at low levels and high levels and coarser at
medium levels. This curve emulates the RMS voltage dimming characteristics of an incandescent lamp such as the tungsten halogen lamp of the Martin™ MAC TW1™.
- Square law – light intensity control is finer at low levels and coarser at high levels.
- Inverse square law – light intensity control is coarser at low levels and finer at high levels.
FOCUS TRACKING sets focus to automatically self-adjust when you use the zoom effect (see “Zoom/focus linking” on page 25).
FOLLOWSPOT MODE enables pan, tilt, or pan and tilt movement to be unlocked so that the head of the fixture can be directed by hand using a user-supplied handle (see “Followspot mode” on page 25). In followspot mode the motors can be applied as a brake to pan, tilt, or both pan and tilt movement to prevent head movement when the fixture is not “manned”; in this case DMX or menu-based control over pan and tilt is still disabled.
• AUTOMATIC LAMP ON gives three lamp strike options:
- When set to Off, the lamp remains off until a “lamp on” command is received via DMX.
18 MAC III AirFX user manual
Page 19
- When set to On, the lamp strikes automatically after the fixture is powered on.
- When set to DMX, the lamp strikes automatically when the fixture begins to receive DMX data, and
lamp power is shut down 15 minutes after the fixture stops receiving DMX data. Automatic lamp strikes are staggered to prevent all lamps from striking at once. The delay is determined by the fixture address. No matter what the AUTOMATIC LAMP ON setting is, the lamp can be struck by sending a lamp on command via DMX on channel 21.
DMX LAMP OFF and DMX RESET define whether the lamp can be powered off, or whether fixture or individual effects can be reset by sending a DMX command on channel 21. If either of these settings are set to Off, you can override this setting and cut lamp power or reset effects by applying a special combination of DMX values (see “MAC III AirFX DMX protocol” on page 43).
PARAMETER SHORTCUTS determines whether the gobo wheels and color wheel take the shortest path between two positions (shortcuts enabled), crossing the open position if necessary, or always avoid the open position (shortcuts disabled).
DISPLAY determines whether the display remains on permanently, or goes into sleep mode 2, 5 or 10 minutes after the last movement of the jog wheel or Escape button.
DISPLAY INTENSITY lets you define the brightness of the backlit graphic display. Select Auto for automatic adjustment to match the ambient light level, or manually set the intensity to a level from 0% to 100%.
DISPLAY ROTATION lets you rotate the display manually through 0°, 90°, 180° or 270° so that it can be read easily no matter how the fixture is oriented. If set to Auto, the MAC III AirFX senses its orientation and rotates the display automatically.
ERROR MODE enables or disables error warnings. If set to Start, the display is activated and lights up if the fixture needs to report an error. If set to Silent, the fixture does not light the display with error warnings but error messages can still be read when the display is activated manually. In both Start and Silent modes, the status LED in the jog wheel lights amber to indicate a warning and red to indicate an error.

Factory settings

FACTORY SETTINGS lets you restore the fixture’s default setup options. Effect calibration is not affected,
so any effects that have been re-calibrated will not be returned to factory calibration settings.

Fixture information readouts

The following fixture information can be called up in the display:
FIRMWARE VERSION displays the currently installed fixture software version.
POWER ON TIME provides two counters:
- The TOTAL POWER ON counter is not user-resettable and displays total hours powered on since
manufacture.
- The RESETTABLE POWER ON counter is user-resettable and displays the number of hours the fixture
has been powered on since the counter was last reset.
LAMP ON TIME provides two counters:
- The TOTAL LAMP ON counter is not user-resettable and displays total hours the lamp has been
powered on since manufacture.
- The RESETTABLE LAMP ON counter is user-resettable and displays the number of hours the lamp
has been powered on since the counter was last reset.
LAMP STRIKES provides two counters:
- The TOTAL LAMP STRIKES counter is not user-resettable and displays the total number of lamp
strikes since manufacture.
- The RESETTABLE LAMP STRIKES counter is user-resettable and displays the number of lamp strikes
since the counter was last reset.
AIR FILTERS provides an alert feature for service interventions:
- The RESETTABLE AIR FILTER counter displays the total number of hours the fixture has been
powered on since the alert timer was last cleared.
- SET TIME ALERT lets you set the number of hours from 1 to 750 you want the fixture to be powered on
before a service alert appears in the display. If you set this figure to 0, the time alert is disabled.
- CLEAR RESETTABLE AIR FILTER lets you reset the resettable air filter counter to zero after
completing service work.
FIXTURE MAC ID displays the fixture’s factory-set MAC (Media Access Control) address.
Control panel operations 19
Page 20
RDM UID displays the fixture’s factory-set unique ID for identification in RDM systems.
FANS SPEED provides separate status readouts from the fixture’s cooling fans.
TEMPERATURE provides a fixture temperature status readout.
POWER UNIT provides the following readouts:
- MAINS VOLTAGE displays a mains power voltage readout measured at the fixture’s mains power input.
- LAMP VO LTAGE, LAMP CURRENT and LAMP WATTAGE display readouts measured at the fixture’s lamp terminals.
- LAMP STATE gives a lamp status readout.
- IGNITER STATE gives an igniter (starter) lamp status readout.
- INTENSITY indicates current lamp intensity.
EVENT LOG VIEWER lets you view event logs in the fixture’s display panel. See “Event log” on page 32.

DMX signal monitoring

The MAC III AirFX provides data on the DMX signal it is receiving in the DMX LIVE menu. This information can be useful for troubleshooting control problems.
RATE displays the DMX refresh rate in packets per second. Values lower than 10 or higher than 44 may result in erratic performance, especially when using tracking control.
QUALITY displays the quality of the received DMX data as a percentage of packets received. Values much below 100 indicate interference, poor connections, or other problems with the serial data link that are the most common cause of control problems.
START CODE displays the DMX start code. Packets with a start code other than 0 may cause irregular performance.
The remaining options under DMX LIVE display the DMX values in a range from 0 - 255 that are being received on each channel.

Test sequence

TEST SEQUENCE activates effects in sequence, allowing you to test them quickly without a DMX
controller:
ACTION lets you start, pause, and stop the sequence. TYPE lets you test all effects, pan/tilt movement only, or the other effects only. REPEAT sets the current test to repeat when finished.
Status readouts for the current test sequence are displayed below the ACTION, TYPE and REPEAT commands.

Manual control

The MANUAL CONTROL menu lets you reset the fixture, strike our douse the lamp, apply effects and move pan and tilt manually.

Setup Wizard menu

The SETUP WIZARD menu gives quick access to the most frequently required items in the control menus.
20 MAC III AirFX user manual
Page 21

Adjusting settings via DMX

Certain fixture settings and parameters can be adjusted from the DMX controller on DMX channels 21 and
22. Commands sent via DMX override any settings entered in the fixture’s onboard control menus. However, to
reset the fixture, reset individual effects or cut power to the lamp via DMX if DMX Reset or DMX Lamp Off are disabled in the control menus, certain conditions must be met (see the notes for channels 21 and 22 in the DMX Protocol table in this manual).
Note also that a lamp off command sent by DMX must be applied for 5 seconds before it executes. These requirements are a safeguard to help you avoid resetting the fixture or powering the lamp off
accidentally.

Resetting

Either the entire fixture or individual effects can be reset to their initial positions. Resetting individual effects can allow on-the-fly recovery if an effect loses its correct position, for example, without having to reset the entire fixture.

Lamp on / off

The lamp can be struck and doused from the DMX controller. A peak of electric current that is many times the operating current is drawn for a fraction of a second 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 electronic circuit breakers. If sending lamp-on commands to multiple fixtures, program a sequence that strikes lamps one at a time.

Adjusting lamp power

If full light output is not required, the power supplied to the lamp by the ballast can be reduced. Reducing lamp power reduces heat output and therefore reduces noise from the cooling fans. It also reduces power consumption, and it helps reduce the gradual fall in output that occurs over the lifetime of a discharge lamp.
Lamp power can be to set to 1500 W (full power), 1200 W, 1100 W, 1000 W or 900 W via DMX using the ballast output control commands available on channel 21.
If the shutter and/or dimmer are closed for longer than 10 seconds, lamp power is automatically switched to 900 W. When the shutter is opened again, the lamp returns to full power.

Illuminating the display

The fixture’s display panel can be brought out of sleep mode with a DMX command. This makes it possible to read the fixture’s DMX address while the fixture is installed in the rig.
After being illuminated in this way, the display will return to sleep mode according to the setting entered in the onboard control menus.

Control menu setting overrides

The following fixture settings can be adjusted via DMX, overriding the settings entered in the onboard control menus. See under “Control panel operations” on page 15 for details of these parameters.
• Dimming curve
• Parameter shortcuts
• Zoom/focus linking
• Pan/tilt limits
• Calibration offsets
Adjusting settings via DMX 21
Page 22

Defining calibration offsets via DMX

The ”Fixture adjustments/calibration (menu override)” DMX channel allows effect offsets to be adjusted and stored in the fixture from the DMX controller.
To adjust an effect offset:
1. Set the effect to a DMX value from 0 to 255 on its own DMX channel (for example, set Cyan to 192 on channel
4).
2. Send a ‘Store’ command for the effect on the Fixture Adjustment/Calibration channel.
The MAC III AirFX now reads the value on the effect channel (192 for Cyan in the example above), translates it to an adjustment value of between -5% and +5% as shown in Figure 12 (+2.5% Cyan adjustment in the example above) and stores that offset in memory.
See ”Fixture adjustments/calibration (menu override)” in the DMX protocol on page 47 for details of the offsets that can be adjusted using this method.
Effect offsets stored in memory are not affected by powering the fixture off and on or by updating the fixture software. To return all offsets to their factory defaults, send a DMX value from 245 to 249 on the ”Fixture adjustments/calibration (menu override)” channel 22 or apply LOAD FACTORY SETTINGS in the FAC TORY SETTINGS menu in the fixture’s control panel.

Effects

This section gives details of the effects that can be controlled via DMX. See “MAC III AirFX DMX protocol” on page 43 for details of the channels used to control them.
Where fine control is available, the main control channel sets the first 8 bits (the most significant byte or MSB), and the fine channels set the second 8 bits (the least significant byte or LSB) of the 16-bit control byte. In other words, the fine channel works within the position set by the coarse channel.

Shutter and strobe effects

The MAC III AirFX’s mechanical shutter provides regular or random strobe and pulse effects with variable speed from 2 Hz to 10 Hz approximately.
To ensure total blackout, the mechanical dimmer also deploys if the shutter is closed for more than 5 seconds.

Dimming

The MAC III AirFX’s mechanical dimmer provides smooth, high-resolution 100 percent fading. 16-bit fine control of the dimmer is available.
To ensure total blackout, the mechanical shutter also deploys by default if the dimmer is reduced to 0% for more than 5 seconds (this function can be disabled under menu).
SHUTTER BLACKOUT in the PERSONALITY control

Cyan, Magenta, Yellow and CTO

The amount of cyan, magenta, yellow and CTO (color temperature control orange) applied to the MAC III AirFX’s light output can be varied from zero to 100%. Color temperature can be varied from 6000 - 3200 K.

Color wheel

The MAC III AirFX features a color wheel with 7 interchangeable dichroic color filters and an open position. Color filters can be applied as split colors or in full-color steps.

Aerial effects

The rotating aerial FX wheel in the MAC III AirFX provides 4 rotating mid-air effect gobos plus an open position. The gobos installed as standard are shown in Figure 14.
Gobos can be selected, indexed (positioned at an angle), rotated continuously, and shaken (bounced). The gobo wheel can also be scrolled continuously or shaken. Indexing, continuous gobo rotation, gobo shake and continuous gobo wheel scrolling are selected on channel 10. Depending on what is selected on this channel, the indexed angle or rotation speed are set on channel 11. If gobo indexing is selected on the first channel, fine control of gobo index angle is available on channel 12.
All gobos are interchangeable, but replacement gobos must match the dimensions, construction and quality of the gobos supplied as standard (see under “Specifications” on page 58). The aerial effect gobos and goboholders in the MAC III AirFX are not interchangeable with the gobos and goboholders in MAC III Profile and Performance fixtures.
Handling, installing and storing the gobos in the MAC III AirFX requires special care. See “Aerial effects in the MAC III AirFX” on page 39 for details.

Wash effect

The MAC III AirFX has a Wash effect that can be faded in and out of the beam, softening the projection.

Iris

The iris can be set to a static diameter, or regular and random pulsing effects can be set with variable speed.
24 MAC III AirFX user manual
Page 25

Focus and zoom

The focus lens focuses the beam from approximately 2 meters (6.5 feet) to infinity. The separate zoom lens varies the focused beam angle from approximately 11.5° to 55° with the standard
lens installed.

Zoom/focus linking

Focus can be linked to zoom so that it automatically adjusts to match changes in zoom angle. Focus on rotating gobos matches zoom closely, while focus on the gobo animation wheel matches zoom best in the center of the zoom range and slightly less precisely at the two extremes of the zoom range.
Linked zoom/focus works within 3 distance ranges:
• Near (5 - 10 meters)
• Medium (10 - 20 meters)
• Far (20 meters - infinity)
To link zoom and focus, select a distance range using the Fixture Control/Settings DMX channel or FOCUS TRACKING in the PERSONALITY menu in the control panel. Then adjust focus to obtain the required degree of sharpness. Linking is now enabled and focus will auto-adjust.

Pan and tilt

16-bit pan and tilt control is available on channels 17 plus 18 (pan) and 19 plus 20 (tilt). Maximum and minimum pan and tilt limits can be set using the control panel (see “Personality – tailoring
performance” on page 17) and via DMX.

Followspot mode

The MAC III AirFX features a followspot mode in which the fixture ignores any pan, tilt, or pan and tilt commands sent via DMX or the control menu, releasing the head for use as a followspot.
In followspot mode, the pan and/or tilt motors can be engaged or disengaged using commands in the control menu. If motors are engaged, they act as a brake to pan, tilt, or both pan and tilt movement to prevent the head from moving when it is not being held in place, but DMX or menu-based control over pan and tilt is still disabled (see “Personality – tailoring performance” on page 17 and “Control panel menus” on page 48).
Followspot handles can be custom-made by the user to suit the user’s own preferences and requirements.

Followspot handles safety precautions

Warning! It is the user’s responsibility to ensure that the followspot handles and any mounting brackets are safe and that the fixture is kept in followspot mode at all times while handles are installed to avoid collision between the followspot handles and the yoke.
Warning! Intermediate brackets for permanent mounting on the back of the MAC III AirFX head must be constructed so that they will not touch the yoke at any point in the head’s tilt range!
Warning! Screws used to fasten any item to the rear of the head may only be fastened into the holes (arrowed in Figure 15) provided in the rear head cover. Do not attempt to fasten any item to the rear of the head by any other method. Screws must not protrude more than 15 mm (0.6 inches) into the rear head cover, or there is a danger that they may damage electrical insulation inside the head and create a risk of serious or lethal electric shock for the operator.
Warning! Followspot handles must be thermally insulated so that it is impossible for the operator to suffer discomfort or a burn injury.

Followspot handles use and construction

The MAC III AirFX’s rear head cover is a magnesium alloy casting. Magnesium alloy is prone to galvanic corrosion when steel screws are fastened into it and has a relatively low resistance to mechanical wear on threads. Self-tapping screws fastened into magnesium alloy should be left there permanently.
Effects 25
Page 26
If you are going to switch between using the MAC III AirFX as a manually-controlled followspot and as a DMX-controlled moving head from time to time, you will need to install and remove followspot handles. In this case, we recommend that you fabricate two intermediate mounting brackets in a suitable material for repeated installation and removal of screws, fasten the brackets permanently to the rear head cover, and use these brackets as mounting points for the followspot handles.
If followspot handles are going to be installed permanently, there is no need for intermediate brackets. The design of the brackets and followspot handles is left up to the user to match user requirements, but the
following points must be noted:
• Intermediate mounting brackets must be as light as possible in order to minimize the effect of their extra
weight on the balance of the head. It may be best to make them in aluminium.
• Four holes (arrowed in Figure 15) are provided in the fixture’s rear head cover for fastening followspot
handle mounting brackets.
• On most MAC III Profile fixtures manufactured before August 2009, the four holes are drilled but not
threaded. If you have reconfigured a MAC III Profile as a MAC III AirFX, check these holes. If they are not threaded, use M6 thread-forming screws (DIN 7500) to fasten mounting brackets. Torx head screws are recommended because considerable force will be required to tighten the screws into the rear cover. If the four holes are threaded, use regular M6 machine screws for attachment.
• Whatever type of screw used, the
portion of the screw that goes into the rear head cover must have a length of between 12 mm (0.47 in.) and 15 mm (0.6 in.).
• The rear head cover becomes very hot.
Ensure that handles are insulated well enough to avoid discomfort or burn injuries for the followspot operator.
• A handle must only be fitted after
followspot mode is enabled and tilt is performed manually. Always remove any handle that is fitted before disengaging followspot mode.
Besides being constructed so that they will not foul the yoke at any point in the tilt range, mounting brackets must match the dimensions shown in Figure 15.
Dimensions in Figure 15 are shown in millimeters:
• 216.8 mm = 8.53 in.
• 230.7 mm = 9.08 in.
Figure 15: Dimensions for followspot handles
• 78.9 mm = 3.11 in.

RDM
The MAC III AirFX can communicate using RDM (Remote Device Management) in accordance with ESTA’s American National Standard E1.20.
RDM is a bi-directional communications protocol for use in DMX512 control systems, it is the open standard for DMX512 device configuration and status monitoring.
The RDM protocol allows data packets to be inserted into a DMX512 data stream without adversely affecting existing non-RDM equipment. The RDM protocol allows a console or dedicated RDM controller to send commands to and receive messages from specific fixtures.

RDM ID

Each MAC III AirFX has an RDM UID that makes it uniquely addressable. This can be found in the control panel menus under FIXTURE INFORMATION. RDM UID shows the fixture’s factory-set unique ID for identification in RDM systems.

RDM communication

The MAC III AirFX will respond to:
1. ”MAC III AirFX supported standard commands”; see page 28.

Service and maintenance

Warning! Disconnect the fixture from power and allow to cool for 2 hours 45 minutes before removing any cover.
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.
This section lists service and maintenance operations that may be carried out by the user. Refer any operation that is not described here to a qualified Martin technician.
The MAC III AirFX requires routine cleaning. The schedule depends heavily on the operating environment. It is essential to follow the cleaning guidelines given later in this section.

Tilt lock

Important! Release the tilt lock before
operating the fixture.
The tilt position of the head can be locked at various angles for service. Push the lock in towards the yoke in one direction to lock the head and back in from the other side to unlock the head.
There is no pan lock on the MAC III AirFX.
Important! Release the tilt lock before
packing the fixture in the flightcase.
Figure 16: Tilt lock

Service utilities

The SERVICE menu in the main menu provides utilities for technicians rigging or servicing the fixture:
PAN/TILT FEEDBACK lets you disable feedback to the fixture software from the pan, tilt and effects positioning systems. If feedback is set to On and a pan, tilt or effect position error is detected, the shutter closes and the effect resets. This feature can be disabled by setting feedback to Off. The Off setting is not saved when the fixture is powered off, and the system will be re-enabled the next time the fixture starts. If a pan/tilt position error occurs and the system cannot correct pan/tilt position within 10 seconds, feedback is automatically disabled.
ADJUST is for use at the factory and by authorized Martin Service technicians only. This menu allows dimmer, shutter, pan and tilt positions to be adjusted after replacement of components, etc. To adjust the default positions of all the MAC III AirFX’s effects, use the CALIBRATION menu instead.
Important! Do not enter the ADJUST menu without service documentation from Martin.
• CALIBRATION sets effects to their factory default positions or lets you set new default positions for calibration purposes. See ”Calibration” later in this chapter for full details.
UPDATE FIRMWARE, updates the firmware (fixture software). For a detailed guide to updating the firmware, see ”Software installation” later in this chapter.
• EVENT LOG gives access to the fixture’s log. See next section.
Service and maintenance 31
Page 32

Event log

The MAC III AirFX monitors performance, any errors or warnings, temperatures, etc. and stores data in an ongoing service event log that can be viewed in the fixture’s display or downloaded to a USB memory device and viewed on a PC.
Power cycle reports are created automatically each time the fixture is powered up. The fixture stores up to 25 power cycle reports in memory. If the memory is full, the oldest report is deleted each time a new report is generated.
A power cycle report lists three types of data:
1. General data, settings 2. Events 3. Dynamic Content
General data, settings displays fixture information and lists current settings. Events is only displayed if any warnings, errors or changes in settings occur, and lists these with the
amount of time that has passed since they occurred. Dynamic content displays technical data for the fixture that is intended to help troubleshooting. It is only
displayed if warnings or errors are listed in the Events section. Dynamic content is updated automatically with current data — and the old data is saved to the event log — every 15 minutes for up to 10 hours. The oldest data is then replaced by new data. If an error or warning occurs, data is updated immediately. Dynamic content can also be updated manually. This can be useful if a fixture does not behave as expected, for example, but the fixture is not showing an error or a warning. the user can check that the DMX start code is zero to eliminate poor data transmission as a possible cause of the problem. To renew the dynamic content in the current power cycle report with the current data:
•select SERVICE
• send the RDM command EVENT_LOG_USER_EVENT_TRIGGER.
To delete all previous power cycle reports in the event log from memory, select SERVICE EVENT LOG Clean Event Log in the control panel.
General Information Personality Settings Adjust Settings Calibration Settings Fixture Information Module Information PCB Information

Viewing the event log in the fixture’s display panel

To view the event log in the fixture’s display panel, select FIXTURE INFORMATION EVENT LOG VIEWER in the control panel.
The EVENT LOG VIEWER displays all the power cycle reports in memory and supplementary information about any event you scroll to. Use the jog wheel to scroll through the power cycle reports. As you scroll and highlight each event, details of the event are shown at the bottom of the display:
TIME gives the time after power up that the event occurred.
DESCRIPTION gives type of event.
VALU E gives either the value of a new personality setting (e.g. On/Off) or the long description of an error code (e.g. FOER = focus error).

Viewing power cycle reports on a PC

To view the current and most recent power cycle reports on a PC:
1. Insert a USB memory device in the fixture’s USB port to open the USB device pop-up window.
2. Select Download Event Log and wait for the log file to be saved to the USB device.
3. Remove the USB memory device, and carry out this procedure with other fixtures if required.
4. Connect the USB memory device to a PC. Logs are stored in the root directory of the memory device in
a folder called EVENT LOGS MAC III SERIES using the naming convention LOG MACIII XXXXXXXXXX.xml (where XXXXXXXXXX is the serial number of the fixture). The XML files can be viewed using any web browser that supports XSLT 1.0 such as Internet Explorer 6, Firefox 3, Google Chrome 1, Opera 9, Apple Safari 3 or later versions.
5. Double-click on the event log to open it in your web browser.
32 MAC III AirFX user manual
Page 33
Event log structure when viewed in a web browser
The title Power Cycle is displayed in red if that power cycle report includes an error. Event log XML files are divided into boxes:
General information lists the most important information held by the fixture.
Personality Settings lists the fixture’s settings at power up.
• Adjustment Settings displays the fixture’s factory adjustment settings at power up. These settings should only be changed by Martin Service or its authorized agents.
• Calibration Settings displays the fixture’s calibration settings at power up. These settings can be changed by the user (see ”Calibration” on page 35).
• Fixture Information displays data from the fixture’s timers when it was last powered up.
Service and maintenance 33
Page 34
• Module Information displays data from the fixture’s effects modules.
• PCB information displays data from the fixture’s PCBs.
The Event Section lists all the errors, warnings and setting changes carried out by the user since the last power cycle in the event log. The Time column on the left of the box displays the amount of time between the fixture powering up and the event. Thus, in the example on the right, a main PCB fan error occurred 2 minutes and 7 seconds after power up and the pan/tilt sensor was not calibrated (warning was listed as ACTIVE) 1 minute and 24 seconds after power up but was calibrated (warning was listed as INACTIVE) 8 minutes and 48 seconds after power up.
Dynamic Content displays the speed of the fixture’s fans, fixture temperatures and other data:
- current data (in the
example on the right, two minutes and one second after power up).
- previously logged data
(captured at 15-minute intervals over a total of up to 10 hours, most recent data at the top — see following example showing time).
The example below in the Dynamic Content section, shows temperature data for the different sensors in the fixture. In the example, the fixture was powered on 3 hours and 15 minutes before the current temperature data was logged. Temperature change over time at 15 minute intervals can be followed in

the table. If you wish, it can also be copied and pasted into spreadsheet software such as Microsoft Excel.
Handling XML log files
The XML event log files can be archived and e-mailed, but you must include the folder templates and its contents MACIII_EventLog.css and MACIII_EventLog.xsl in the same folder as the XML files so that web browsers can view the event logs correctly:
Zipping the EVENT LOGS MAC III SERIES folder before storing or sending should ensure that the nested
templates folder is correctly included.

Calibration

The CALIBRATION and ADJUSTMENT menus let you 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. Fixtures are calibrated at the factory, and further calibration will normally only be necessary if fixtures have been subjected to abnormal shocks during transport or if normal wear and tear has affected alignment after an extended period of use.

Calibrating pan and tilt sensors

When you select PAN/TILT SENSOR CALIBRATION, a display message appears asking you to move pan and tilt to their end stop positions. To calibrate pan and tilt:
1. Move pan to its end stop position by rotating the yoke clockwise (as seen from above the head looking
down at the base) to maximum pan.
2. Move tilt to its end stop by tilting the head to its maximum angle with the front glass pointing away from
the display panel.
3. Press the jog wheel to register the positions. The fixture will display Saving...
Warning! As soon as you exit pan/tilt sensor calibration, the head will move to its original position.
4. Make sure that you are ready for the head to move, then press the Escape button to exit pan/tilt sensor
calibration. The head will now pan and tilt back to where it was before you entered calibration mode.
Service and maintenance 35
Page 36

Calibrating effects

Calibration can be carried out via DMX (see “Defining calibration offsets via DMX” on page 22) but the easiest approach is probably to set multiple fixtures to the same position (e.g. dimmer open 1%) and then calibrate each fixture using its onboard control panel while comparing its light output with a reference fixture.
The calibration range available for each effect varies but is approx 5%. After selecting a calibration value, click on the jog wheel to set the effect to that value.

Loading and storing default calibration offsets

LOAD DEFAULTS? lets you load the factory default calibration offsets stored in memory. SAVE FACTORY DEFAULT? lets you overwrite the factory default calibration offsets stored in memory with
any new offsets you have defined. Overwriting is permanent, so once you have saved new factory default offsets, LOAD DEFAULTS? will reload the new offsets.

Software installation

The currently installed firmware (fixture software) version can be viewed under FIXTURE INFORMATION in the main menu. Firmware updates are available from the Martin website and can be installed using either of two methods:
• a USB memory device loaded with ‘bank’ files and inserted in the MAC III AirFX’s USB port, or
• a Windows PC loaded with ‘MU3’ files and running the Martin Uploader application, connected to the MAC III AirFX’s data input socket via a Martin Universal USB/DMX™ or a Martin DABS1™ hardware interface.
Module firmware updating
Calibration data is stored in the relevant modules wherever possible so that a module will stay calibrated if is removed from the fixture or installed in another fixture. If firmware is updated, a red spot next to the battery icon in the display (arrowed in illustration on right) blinks while data in the modules is being updated. This can take up to a minute. Do not switch the fixture off while the spot is blinking, or firmware will be corrupted.

Installing using a USB memory device

The following are required in order to install firmware using a USB memory device:
• The MAC III AirFX firmware ‘bank’ update file, available for download from the Product Support area of the Martin website at http://www.martin.com.
• A USB memory storage device (e.g. USB stick) with the update file copied from a PC into the memory device’s root directory.
To install the firmware:
1. Download the firmware ‘bank’ from the MAC III AirFX support page on the Martin website at
www.martin.com, read the firmware release notes carefully to check for any instructions or warnings, and copy the ‘bank’ to the root directory of a USB memory stick.
2. Disconnect the data link from the MAC III AirFX.
3. Insert the USB stick in the MAC III AirFX’s USB host socket. The fixture should recognize the USB stick,
illuminate the display panel and show the UPDATE FIRMWARE window in the display. Alternatively, scroll to the UPDATE FIRMWARE menu under SERVICE in the control panel.
4. Select BANK. Scroll up and down to see the firmware versions present on the USB stick and in the
fixture’s internal memory. LOCATION indicates whether the firmware is located on the USB stick or in internal memory.
5. If you scroll to a firmware version on the USB stick and click the jog wheel, the firmware is downloaded
to internal memory (where it will be available for future firmware updates), validated, unpacked and installed, and the fixture will restart using the new firmware.
6. Remove the USB stick. The newly-installed firmware version will now be displayed in the FIXTURE
INFORMATION menu.
7. Reconnect the data link.
Zoom-focus linking is reset to default (medium distance) when new software is uploaded. Other fixture information and settings are unaffected.
36 MAC III AirFX user manual
Page 37

Cleaning

Forced upload
The fixture can be forced to automatically upload a software file from a USB stick if the Escape button is held down during power up. We recommend that only one software update file is located in the memory device’s root directory, but in the event that several versions are available, the fixture will upload the file with the most recent software version.

Installing using a PC and hardware interface

The following are required in order to install firmware using a PC and hardware interface:
• The MAC III firmware ‘MU3’ update file, available for download from the Product Support area of the Martin website at http://www.martin.com.
• A Windows PC running the latest version of the Martin Uploader™ application (also available for download free of charge from www.martin.com) and loaded with the firmware update file.
• A USB/DMX hardware interface device such as the Martin Universal USB/DMX™ or Martin DABS1™.
To install the MAC III firmware:
1. Download the firmware ‘.MU3’ file from the MAC III AirFX support page on the Martin website at
www.martin.com to the PC.
2. Read the firmware release notes carefully to check for any instructions or warnings.
3. Follow the instructions for an auto upload/upload via DMX in the Martin Uploader application help files
and supplied with the hardware interface.
Regular cleaning is very important for fixture life and performance. Buildup of dust, dirt, smoke particles, fog fluid residues, etc. degrades the fixture’s 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 III AirFX. 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 fixtures within their first 25 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. If in doubt, consult your Martin dealer about a suitable 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.
Service and maintenance 37

Cleaning and replacing the air filters

The item AIR FILTERS in the FIXTURE INFORMATION menu is intended to be used to monitor intervals between air filter cleaning, although this counter can be used to monitor any aspect of the fixture.
When air filters require cleaning:
1. Disconnect the fixture from power and allow
the components to cool for 2 hours 45 minutes.
2. See Figure 17. On each side of the head, use
a flat-bladed screwdriver to lever the front edge of each filter holder slightly away from the head, then slide the screwdriver across to each corner and gently lever each corner free. Pull the filter holders forwards to unclip and remove them.
Figure 17: Removing head air filters
3. See Figure 18. On each side of the base, pinch the air filter
holders in from the sides as illustrated, then pull the center of the holders outwards to unclip and remove them.
4. Clean the air filter elements. If they are saturated with smoke
fluid, soak them in warm, soapy water and blot dry. If the filters cannot be cleaned completely or are not in perfect condition, replace them with new items.
5. Pinch the base filter holders in from the side and engage the
ends of the filter holders their slots to clip them back into position.
6. See Figure 19. Engage the three tabs in the head filter
holders in their slots in the head, pinch the foremost corners of the filter holder together slightly and press them into the head to clip them back into position.
7. Check that all filter holders are correctly installed so that there
is an airtight seal around all their edges.

Cleaning the fixture

To clean the head:
1. Power the lamp off, allow components to cool for 2 hours 45 minutes and
disconnect the fixture from power.
2. Remove both head covers by loosening their quarter-turn retaining
screws (see Figure 20).
3. Vacuum or gently blow away dust and loose particles inside the head
with compressed air.
4. Carefully clean the optical components, but note that special precautions
apply to the gobos (see “Aerial effects in the MAC III AirFX” on page 39). 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 fans and air vents with a soft brush, cotton swab,
vacuum, or compressed air.
6. Reinstall the head covers.

Lubrication

Figure 20: Head cover
screws
The MAC III AirFX 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.

Replacing a color filter

Note: Wear cotton gloves while handling color filters and use only genuine Martin filters.
1. Power the lamp off and allow the fixture to cool for 2 hours 45 minutes. Disconnect the fixture from
power.
2. The top of the head is above the text on the lamp cover. Lock the head in a convenient position for
access to the top of the head.
3. Remove the two retaining screws (see Figure 20) from the top cover and lift it away from the head. Let
the cover hang on its safety wire or unclip the safety wire and remove the cover completely.
4. Rotate the color wheel until the filter you want to change is accessible. Lift the outer edge of the filter
away from the color wheel slightly to release it, then pull it free of its retention spring and out of the color wheel.
5. To insert a filter, slide it into the color wheel so that it clips under its retention spring and make sure that
the filter’s outer edge engages in the lip on the edge of the color wheel.
6. If no further service work is to be carried out, reinstall the top cover with its safety wire and release the
tilt lock.

Aerial effects in the MAC III AirFX

The MAC III AirFX uses specially-designed borosilicate 3.3 aerial effect gobos with a heavy matted aluminum coating that require particularly careful handling and storage.
The use of metal gobos in the MAC III AirFX is not recommended. Do not use gobos with dark coatings on any side, as these will absorb heat – either directly from the lamp or
reflected back from other optical components – and will not be durable.

Handling and storage

1. Store all gobos in a dust-free environment with approx. 50% humidity.
2. Always use clean gloves when handling gobos.
3. Avoid touching the other gobos when taking out a gobo from the rack: the sharp edge of one gobo can
scratch the others.
Service and maintenance 39
Page 40
4. Clean the coated side of gobos with dust and oil-free compressed air only.
5. Clean the uncoated side of gobos with photographic quality lens-cleaner and optics cleaning tissues.
Use a repeated dabbing action rather than a rubbing action.
6. Avoid scratching coated and uncoated sides.
7. Never place a gobo with the coated side face-down on any surface.
8. Mount the gobo with the matted coating towards the lens.

Replacing aerial effect gobos

Important! The gobo can fall out if the spring is inserted backwards.
Do not lubricate gobo bearings: excess grease can cause loss of step.
Correct gobo orientation is critical. Read the guidelines in Figure 24 carefully before installing a gobo.
To replace a gobo:
1. Open the top cover as described under “Replacing a color filter”
on page 39.
2. Note the positions of connectors, unplug them, remove the two
Torx 20 screws that hold the effects module in the head and remove the module.
3. Rotate the aerial effects wheel
until the gobo you want to replace is accessible.
4. See Figure 22. Loosen the two
Torx screws (arrowed) on the goboholder retaining clips on either side of the gobo and slide the clips outwards to release the gobo.
5. Holding the goboholder by its
teeth, lift it out of the wheel.
6. 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.
Figure 21: Rotating gobo holder
Figure 22: Goboholder retaining screws
7. Refer to Figure 21 and Figure
24. Hold the gobo over the holder with the side that must face towards the lamp facing upwards, towards the spring. See Figure 23. Line up the mark A in the new gobo with the magnet B in the holder (the marks in gobos are also visible at the top of each gobo in Figure 14 on page 24).
8. Place the gobo in the holder
and Insert the spring with the narrow end against the gobo as shown in Figure 21. To 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.
9. Check that the gobo is seated flush against the holder and that the spring is pressed as flat as possible
against the back of the gobo.

10. Line up the goboholder, rotating the aerial effects wheel if necessary, so that the magnet faces in the
same direction as the magnets on the other goboholders in the aerial effects wheel (for example, all magnets facing outwards), then fit the goboholder into position on the gobo wheel, engaging its teeth in the central activation cog.
11. Slide the goboholder retaining clips back into position so that they engage in the groove in the
goboholder. Tighten the screws (arrowed in Figure 22), adjusting the position of the clips carefully so that the goboholder is held securely. The gobo must be able to rotate freely but must not be loose. Rotate the goboholder several times with your finger after you have tightened the screws to check this, and adjust the position of the clips if necessary.
12. If no further service work is to be carried out, reinstall the top cover with its safety wire and release the
tilt lock.

Gobo orientation

abc
abc
The orientations shown in Figure 24 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. To minimize the risk of heat damage, priority must be given to installing gobos with their more reflective sides facing the lamp.
Coated Glass Gobos
The heavy matted aluminum coated borosilicate gobos in the MAC III AirFX are factory-installed with the more reflective sides facing towards the lamp. Replacement gobos must also be installed with more reflective sides facing the lamp.
More reflective side towards lamp
To minimize the risk of gobo overheating and damage, turn the more reflective side of a coated gobo towards the lamp.
Less reflective side away from lamp
The less reflective side of a coated gobo will absorb less heat if it faces away from the lamp.
Textured Glass Gobos
Textured side towards lamp Smooth side away from lamp
Textured glass gobos in the MAC III AirFX sit most squarely in the gobo wheel with the textured side towards the lamp. If in doubt, consult your Martin dealer or gobo supplier.
