INTRODUCTION

Thank you for selecting the Martin RoboScan Pro 918. This scanner, with its highly efficient optical and thermal
design, provides quiet operation and crisp, bright output in a compact, easy-to-handle package.

This manual covers all models of the RoboScan Pro 918 and describes the features found in CPU software version 1.4.
The latest Pro 918 information and software is available from the Martin Professional web site at http://
www.martin.dk.

S

AFETY PRECAUTIONS

The RoboScan Pro 918 is for professional use only. It presents potential risks due to electrical shock, heat and ultra­violet radiation burns, lamp explosion, falls, high-in tensity light , and fire. A thorough understandin g of the dangers,
genuine concern for safety, and attention to detail are required to prevent accidents. Read this manual before power-

ing or installing the fixture, follow the safety precautions listed below and observe the warnings in this manual
and printed on the fixture, and always double check the safety conditions. If you have questions a bout how to

operate the Pro 918, please contact your Martin dealer for assistance.

• $OZD\VýGisconnect the fixture from AC power before:

- Changing the transform er or ballast settings

- Installing or removing the lamp

- Checking or replacing fuses

- Removing any cover or part

• Replace the lamp before usage exceeds the maximum rated service life or if the lamp becomes defective or worn out.
Allow the fixture to cool for 15 minutes before replacing the lamp.

• Keep all combustible materials (for example fabric, wood, paper) at least 0.5 meters (20 inches) away from the fixture.
Keep flammable materials well away from the fixture.

• For protection against dangerous electric shock, always ground (earth) the fixture electrically. Use only a source of AC
power that complies with local building and electrical codes. Do not expose the fixture to rain or moisture.

• Ensure that the air flow through fans and vents is free and unob structed.

• When suspending the fixture above ground level, verify that the structure can hold at least 10 times the weight of all
installed devices and secure the fixture with an approved safety cable. Block access below the work area whenever
installing or removing the fixture.

• Refer any service operation not described in this manual to a qualified technician.

• The covers get very hot under normal operation: to avoid burns, locate the fixture where it cannot be accidentally
touched or bumped, and allow the fixture to cool before servicing.

• Do not illuminate surfaces within 1 meter of the fixture.

• Never place filters or other materials over the lens or mirror.

• Do not operate the fixture if the ambien t temperature (Ta) exceeds 40° C (104° F).

• Do not look directly into the light from a close distance.

• Never op e rat e the fixture without all lenses and co vers installed: an unshielded lamp can e xp lod e with ou t warn in g a nd
emits dangerous UV radiation tha t can cause burns and eye damage.

• Do not modify the fixture or install other than genuine Martin accessories and upgrade kits.

NSTALLING OR CHANGING THE LAMP

The RoboScan Pro 918 is designed to work with the Philips MSR-575/2, Philips MSD-575, or the Osram HSR-575/2
discharge lamp. Installing any other lamp may damage the fixture. The lamp holder is pre-adjusted at the factory; pre-
cise alignment may be necessary due t o sl ight variations between lamps. The procedure is described on page 21.

WARNING!

Disconnect the fixture from AC power before proceeding. Always wear safety

goggles to protect your eyes and allow a hot lamp to cool for at least

15 minutes before removing it from the fixture.

1.

The RoboScan Pro 918 must be cool and isolated from AC power. Remove the 2 screws (A) securing the
lamp assembly to the back plate. Gently pull out the assembly.

2.

If changing the lamp, remove the old lamp from the socket.

3.

Holding the new lamp by its ceramic base (do not touch the glass), insert it firmly and squarely into the lamp
socket. Cle an the gla ss b ulb with the cloth su pplied with the lam p , particularly if y our fingers touc h the glas s .
A clean, lint-free cloth wetted with alcohol may also be used.

4.

Reinsert the lamp assembly and replace the screws.

5.

Before turning the lamp on, reset the

RLAH

and

RLST

counters. See “Readouts” on page 11.

Setup

P

OWERING THE FIXTURE

WARNING!

For protection from dangerous 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.

1.

Verify that the voltage and frequency settings match the local AC supply. These settings are printed on the
serial number label next to the control panel. If the settings do not match the supply, then the ballast and
transformer must be rewired as described under “Changing voltage and frequency settings” on page 18.

2.

You may need to install a cord cap that fits your supply on the power cable. Following the manufacturer’s
instructions, connect the wires as shown below. Note: 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.

3.

Verify that the supply cable is undamaged and rated for the current requirements of all connected devices.
Do not connect the Pro 918 to a dimmer system: doing so will damage the fixture.

Rigging

The mounting bracket allows the Pro 918 to be rigged at any angle. The figure below shows the index position of the
balance point at different angles. Balancing the fixture makes it more stable and easier to work with, but it can be hung
out of balance if necessary.

WARNING!

Attach an approved safety cable to the eye hook.

1.

Loosen the clamps (B) on each side of the mounting bracket, slide the
bracket to the approximate position, and partially tighten the clamps.

2.

Loosen the swivel locks (E) and tilt the bracket to the desired angle.
Partially tighten the locks.

3.

Bolt rigging clamps that ca n bear at l east 10 times the we ight of the fi x­ture to the mounting bracket. 1 clamp may be bolted to the center hole
or 2 clamps may be bolted to the 2 outside holes (C). See page 31 for
clamps available from Martin.

4.

Verify that the structure can bear at least 10 times the weight of all
installed fixtures, clamps, cables, auxiliary equipment, etc.

5.

Block access below the work area. Working from a stable platform,
place the fixture on the rigging.

6.

Install a saf ety w ire tha t can bea r at leas t 10 time s the w eight of the fi x­ture. Use the e y e hook (D ) to fasten the safety wire to the fixt ure .

Never
use the carrying handles or mounting bracket for secondary attach­ment.

7.

Tighten the rigging clamp(s) securely to the structure.

8.

Fine-tune the position and the fully tighten the slide clamps and swivel
locks.

C

ONNECTING THE SERIAL LINK

The default pin-out is compatible with DMX-512.

The Pro 918’s 3-pin data sockets are configured for DMX controllers, i.e., pin 1 to shield, pin 2 to cold (-) and pin 3 to
hot (+). As many devices have 5-pin connecto rs or 3-pin connect ors with reversed polarity on pins 2 and 3, adap tor
cables may be required.

1.

Connect the controller’s data output to the RoboScan Pro 918’s data input. For a

• DMX controller with 5- pin output: use a cabl e with 5-pin male and 3-p in female connectors such as P/N 11820005.
Pins 4 and 5 are not used.

• DMX controller with 3- pin output: use a normal cable with 3-pin male and female connectors.

• Martin RS-485 Protocol controller: use a phase-reversing cable, such as P/N 11820006, with 3-pin male and female
connectors, or reconfigure the data sockets as described on page 19.

Setup

2.

Continue the link: connect the output of the fixture closest to the controller to the input of the next fixture.
Use a phase-reversing cable when connecting a DMX-standard (pin 3 +) device to a Martin-standard (pin 3

-) device.

3.

Insert a male 120

Ω

XLR termination plug in the output of the last fixture on the link.

Tips for building a serial link

• Use shielded twisted-pair cable designed for RS-485 devices: standard microp hone cable cannot transmit DMX data
reliably over long runs. For links up to 300 meters (1000 ft.) long, you can use 24 AWG, low capacitance, 85-150 ohm
characteristic impedance, shielded cable with 1 or more twisted pairs. For runs up to 500 meters (1640 ft.) use 22 AWG
cable. Use an amplifier if the serial link exceeds 500 meters.

• Never use a “Y” connector to split the link. To split the serial link into branches use a splitter such as the Martin 4­Channel 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 on the link. The termination
plug, which is simply a male XLR connector with a 120 ohm, 0.25 watt resistor soldered between pins 2 and 3, “soaks
up” the control signal so it does not reflect back down the link and cause interference. If a splitter is used, terminate
each branch of the link.

OPERATION

This section describes the RoboScan Pro 918’s controllable effects and the options for customizing them for your
application. Selecting options from the menu is described in the previous section.

RS-485

CONTROL

The Pro 918 may be controlled with the Martin 3032 controller with version 2.04 or later software. While the Pro 918
is not officially implemented in version 2.04, it may be set up and operated as a MAC 500.

For the fixture to respond, t he prot ocol se tting (

PSET) must be set to Martin (MART) or automatic proto col d etec-

tion (

SPEC/AUTO) must be enabled. If automatic protocol detection is enabled, send one dummy command

before sending real commands.

DMX-512

CONTROL

The Pro 918 has 4 DMX control modes wit h different channel requirement s and characteristics. Mode selection will
depend on the controller and your programming preferences.

Tracking control

Tracking is available in all 4 DMX modes. With tracking control, the controller calculates the positions along the path
between an effect’s starting point and it’s ending point. It uses the fade time t o calculate the change (delta ) of each
update or refresh, which the fixture “tracks.” For smooth movement with any fade time, the Pro 918 has a filter algo­rithm that looks at several position updates (samples), and calculates the ideal speed.

This algorithm is adjustable to compensate for controllers that calculate position changes unevenly. In most cases the
default settings work well.

If movement is not satisfactory there are 2 parameters that can be adjusted. The first is the calculation method used and
is selected under

SPEC/TRAC/MOdE. MOd1, the default, calculates speed based on the absolute value of the

change in DMX; it is the best choi ce with con trollers t hat calcul ate inte rmediate po sitions tha t are clos e to the lin e of
travel. MOd2 uses the real value of the DMX delta to calculate speed and 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

SPEC/TRAC/CAL. Increasing the number of samples increases the distance over which speed is calcu-

lated, making movement smoother but less r e sponsive to sudden changes.
The ideal settings for both parameters will vary from controller to controller: experiment for best results. The real

value algorithm (MOd2) is recommended when using the Pro 918 with the Martin Lighting Director system.

Vector control

With vector control, available in DMX modes 3 and 4, the fixture is given just 1 position - the end position - and a
speed, which is set on a separate channel. Fo r smooth movement, the fade time must be set to 0. With controllers that do
not have programmable fade times, vector control provides a way to set speed. Because the end point and speed are
known from the beginning, vector co ntrol resul ts in smooth m ovement regardless of the fade time or the c ontroller’s
processing power.

The speed channels allow vector control to be turned off, resulting in tracking control. In addition, they offer a “black­out speed,” described below, and overrides of the PTSP (pan/tilt speed) and SCUT (shortcuts) personality settings.

8-bit versus 16-bit pan/tilt resolution

With 8-bit pan/tilt resolution, the pan and tilt are divided into 256 equal increments. Finer position control and
smoother movement is provided in the 16-bit modes, which divide the full pan range into 6400 increments and the full
tilt range into 1280 increments.

S

TAND-ALONE CONTROL

The Pro 918 has test and demonstration sequences that can be run from the control panel. See page 12 for details.

ONTROLLABLE EFFECTS

All mechanical effects are reset to a “home” position when the fixture is powered up. They can also be rese t via DMX
if necessary. Accidental resets can be prevented by turning DMX Reset (

SPEC/dRES) off.

An on-the-fly position correctio n system a utomatic ally corrects th e positio n of the color wheels, fixed-gobo wheel, and
rotating gobos. This feature can be disabled by turning Effects Feedback (

SPEC/EFFb) off.

The Studio Mode setting (SPEC/MOdE) allows operation to be optimized for speed (NORM) or quietness
(

STUd).

Lamp

With the default setting, the lamp remains off until a “lamp on” command is sent from the controller. Note: A strong
surge of electric current is drawn for an instant when striking a discharge lamp. Striking many lamps at once may cause
a voltage drop large enough to prevent lamps from striking or trip the main circuit breaker. If sending “lamp on ” com­mands to multiple fixtures, program a sequence that strikes lamps one at a time at 5 second i nt ervals.

The Pro 918 automatically strikes the lamp within 90 seconds of being powered on if the Automatic Lamp On
(SPEC/ALON) setting is turned on. A delay determined by the address staggers lamp strikes to prevent excessive
current draw.

Lamp power can be turned off from the controller. Be careful: it is not possible to strike the lamp within 8 minutes of
having switched it off. Accidental lamp off commands can be prevented by turning DMX Lamp Off (SPEC/

dLOF

) to off.

Pan and tilt

The mirror pans 180° and tilts 72°. Movement may be optimized for speed by setting the pan/tilt speed (PTSP) per-
sonality to

FAST, or for smoothness by setting it to SLOW. The setting may be overridden on the speed channel in

vector mode. Setting the movement speed to “blackout” in vector mode causes the shutter to black out the light while
the mirror is moving.

The pan and tilt channels (DMX) can be inverted and/or swapped using the pan/tilt (PATI) menu.

Color wheels

The Pro 918 has 2 9- posi tio n-pl us-o pen color w hee ls, yi eld ing a
total of 100 possi ble combinations. In th e standard configura­tion the wheels combine in 67 useful ways that can be called on
1 DMX channel. The filters on color wheel 1 are easily replace­able, allowing you to configure the color wheel to suit your
taste. See page21 for details .

Both wheels can be scrolled, allowing for split color effects,
snapped to fixed positions, and continuously rotated in both
directions at different speeds. The 67 co lors can be called ran­domly on DMX channel 4.

The shortcuts (

SPEC/SCUT) setting determines whether

the wheels take the shortest path to the next position or turn in
one direction only. The setting may be overridden on the speed
channel in vector mode.

Setting the color speed to “blackout” in vector mode causes the shutter to black out the light while the wheels are mov­ing.

Focus

The beam may be focused f rom 2 meters (6.5 feet) t o infinity. Depending on model, the beam angle is 17° or 23.5°.

Iris

The iris closes from full open down to 10 percent . There are 6 variable/rand om pulsa tin g iri s effects callab le on cha n­nel 9. These can be disabled by switching DMX Macros (

SPEC/dMAC) off.

Operation

Fixed (static) gobos

The fixed-gobo wheel provides 9 met al gobos p lus an open posi­tion. It has 2 operating modes. In “fixed” mode (

SPEC/

gMOd/FIX

), the wheel steps between fixed positions and

shakes at variable speeds. In “scroll” mode (

SPEC/gMOd/

SCRL

), the wheel scrolls continuou sly, shakes at 1 speed, a nd

rotates at variable speed.

Setting the fixed-gobo speed to “blackout” in vector mode causes
the shutter to black out the light while the wheel turns from one
position to another. The Shortcuts (

SPEC/SCUT) setting

determines whether the gobo wheel takes the shortest path to the
next position or turns in one direction only. The setting may be
overridden on the speed channel in vector mode.

Rotating gobos

The Pro 918 has 5 rotating gobo positions. Gobos may be rotated
in both directions at varying speeds or indexed to any position.
The function and gobo are selec ted on channe l 5 and the velocity
or index position a re selected on channel 6. Sett ing the rotat ing­gobo speed to “blackout” in vector mode causes the shutter to
black out the light while the wheel turns from one position to
another and, if indexing is selected, while the gobo rotates
between positions.

To change the gobos, see “Changin g r otating gobos” on page 20.

Rotating prism / variable frost

The 3-facet prism can rotate in both directions at varying speeds.
There are 8 preprogrammed macros th at combine the prism wi th
rotating gobos on ch annel 10. These can be disabled by switching
DMX Macros (

SPEC/dMAC) off. Setting the prism speed to

“blackout” in v ect or m ode cau ses th e sh utt er to black out the light
while the prism moves in and out.

An optional frost filter may be in stalle d in pla c e of t he rota ting p rism to provide a variable frost ef fect . If t he fro st filter
is installed, the fixture type personality (

SPEC / FTYP) must be set to “FROS” to enable the frost variation of the

protocol.

Dimmer / shutter

The mechanical dimmer/shut ter system provides smooth, high-resolution 10 0 percent dimming, “instant” open and
blackout, random and variable strobe effects up to 23 Hz, and random and variable pulses in which the di mmer snaps
open and slowly dims or snaps cl osed and slowly opens. The pulse and rando m strobe effects can be disabled by
switching DMX Macros (

SPEC/dMAC) off.

The Dimmer Mode (SPEC/dMOd) setting allows you to select between linear or simulated tungsten fade curves.
The fade time must be 0 to simulate tungsten dimming.

EPLACING FUSES

The RoboScan Pro 918 has 5 fuses. The main fuse is located in the power inlet and may be replaced wit hout openin g
the fixture. Note: The main fuse may need to be replaced with one of another value when rewiring the fixture for oper­ation at a different AC voltage. The fuses for each of the 3 low-voltage power supplies are located on the printed circuit
board. If one of the circuit board LEDs does not light, one of these fuses may be blown. To replace:

1.

Access the printed circuit board as described above.

2.

Locate and replace the defective fuse with a time-delay fuse of the same rating. Fuse locations are shown
on the PCB layout diagram and their values are listed in the specifications.

The fifth fuse is located on the mains filter and power protectio n circuit board, located between the ballas t and the AC
power inlet. If this fuse is bl own there will be no power to th e transforme r and the fixture will appear dead, but there
will still be mains voltage on the ballast. To replace the fuse:

1.

Make sure the RoboSc an Pro 918 is isolat ed from AC power. Access the main s filter c ircuit bo ard fuse a s
described abov e .

2.

Remove the fuse with tweezers or a similar tool.

Replace only with a special fast-acting fuse of the

same rating (P/N 05021010).

3.

Replace the ballast/transformer cover.

PDATING SOFTWARE

The latest software for the RoboScan Pro 918 is available from your Martin dealer and the Martin Professional web
site. Please r ead the update notes bundled with the software. Up date software is uploaded to t he RoboScan P ro 918
using a Martin uploader such as the MBPP1.

Normal upload

Connect the uploader to the fixture just like a controller. Under normal conditions, software can be install ed from a
remote locatio n - th ere is no need t o set t he Ro boSca n Pro 918 to boot mode. P lease refer to t he up load er manua l f or
further instructions.

Boot mode upload

If the data is corrupted during transmission, a check-sum error (CSER) will occur and after 15 seconds the fixture will
automatically switch to boot mode (

UPLd) and be ready for a boot-mod e upload as described below and in the

uploader manual.

If a software upload to the RoboScan Pro 918 is interrupted, the fixture must be powered off for at least 10 seconds
before a new upload can be attempted. When powered on, a check-sum error will occur and it will automatically go
into boot mode, ready for a second upload attempt. Select boot mode upload on the uploader.

If there is no functional software in memory, the fixture must be set to boot mode manually before starting the upload.
If the control panel works, select

UPLd from the SPEC menu and confirm when SURE is displayed by pressing

USTOM GOBOS

For best focus, custom gobos fo r th e Rob oSca n Pr o 918 sh ou ld be mad e wit h the artwork reversed on the c oated side.
See page 31 for gobo specifications.

Chrome-coated glass gobos are no t recommended: they absorb more heat than enhan ced aluminum gobos and are
likely to break or oxidize. The lifetime of chrome gobos is extremely short in the Pro 918; but, if used, their lifetime
can be extended somewhat by inserting the gobos with the coated side towards the lamp.

C

Basic Service and Maintenance

5.

Using either a controller or the control panel, strike the lamp and focus the light on a flat surface.

6.

Center the hot-spot (the b rightest part of the beam) usin g the 3 ad justm ent scre w s. Turn one screw at a time
to drag the hot-spot diagonally across the projected image. If you cannot detect a hot-spot, adjust the lamp
until the light is even.

7.

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

8.

If the light is brighter around the edge than it is in the center, or if light output is low, the lamp is too far back
in the reflector. “Push” the lamp out by turning the screws counterclockwise 1/4-turn at a time until the light
is bright and evenly distributed.

C

LEANING

Optical components

Be very careful when cleaning the optical components. The colored surface on the dichroic filters is achieved by means
of special multi-layer coatings and even small scratches may be visible. Residues from cleaning fluids can bake onto
components and ruin them.

1.

Allow the components to cool completely.

2.

Wash dir ty lenses and filters with isopropyl alcohol. A generous amount of regular glass cleaner may also
be used, but no residues may remain.

3.

Rinse with distill ed water. Mixing the water with a small amount of wetting agent such as Kodak Photoflo will
help prevent streaking and spotting.

4.

Dry with a clean, soft and lint-free cloth or blow dry with compressed air.

Fans

To ensure pr oper cooling of the fixture, it is imp ortant tha t the fans are free of du st. Vacuum or gently wipe the fans
clean if they are dirty.

L

UBRICATION

The focus mechanism slides on 2 metal pi ns that must b e lubricated periodica lly. Check the focus mechanism when­ever the fixture is open for service and lubricate the slides if movement is rough. Lubricate the rotating-gobo bearings
if movement is rough on slow rot a tion or if they become noisy.

1.

Fill a syringe with Martin P/N 37302003, “Silicone oil, 500 ml,” or P/N 37302004, “Silicone oil, 200 ml, in
applicator bottle.”

2.

Apply a few drops of oil to both slides. The oil will be distributed by the action of the focus mechanism. Be
careful not to get oil on other parts.

3.

Apply a few drops of oil to each rotating-gobo bearing from the lamp side of the wheel. Remove excess
lubricant and be careful not to get oil on other parts.

the lamp feedback circuit fails. The fixture
may be operated but remote lamp on/off
may be effected.

• Contact Martin service personnel for
assistance.

Hot (Hot lamp) ... you attempt to strike the lamp within 8

minutes after having switched it off. The fix­ture will store the ‘Lam p ON’ in struction and
strike the lamp once the 8 minute period
has elapsed.

• Wait until the lamp strikes.

PTER (PCB temp. error)
FTER (FX temperature error)

...there is a malfunction in the PCB or
effects section temperature sensing circuit.

• Contact Martin service personnel for
assistance.
