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.

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.
