SAFETY PRECAUTIONS

• The RoboScan 812 is NOT for domestic use.

• 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 elec-

trical codes, and do not expose the fixture to rain or moisture. Disconnect the fixture

from AC power before removing any cover or part.

• Disconnect the fixture from AC power if the lamp blows. Allow the fixture to cool for

10 minutes before installing a new lamp.

• Do not illuminate surfaces within 30 cm (12 inches) of the fixture.

• Do not place filters or other objects over the lens or mirror.

• Keep all combustible materials (for example fabric, wood, paper) at least 10 cm (4

inches) away from the fixture. Keep flammable materials well away from the fixture.

• Provide a minimum clearance of 10 cm (4 inches) around the fan and air vent.

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

• 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.

• For protection against dangerous UV radiation, never operate the fixture with missing

INSTALLATION

The RoboScan 812 is delivered fully adjusted from the factory; only a few setup steps are

necessary. Please follow them carefully to get the most out of your new equipment.

Unpacking

The packing material is carefully designed to protect the fixture during shipment - always

use it or a flight case to transport the fixture.

The RoboScan 812 comes complete with the following items:

• 150 W Martin Metal Halide discharge lamp

• 5 meters XLR-XLR cable

• mains cable

• mounting bracket and hardware

• this user manual

Installing a Plug on the Power Cord

WARNING!

For protection from dangerous electric shock, the fixture

must be grounded (earthed). The AC supply shall be fitted

with a fuse or circuit breaker and ground-fault protection.

The RoboScan 812 is delivered without a plug on the power cord. Following the manufac-

turer’s instructions, install an approved 3-prong grounding-type plug that fits your supply.

Connect the wires to the pins as listed below. The table shows some possible pin identifica-

tion schemes; if the pins are not clearly identified, or if you have any doubts about proper

installation, consult a qualified electrician.

Checking voltage and frequency settings

The RoboScan 812 voltage setting must be within 5% of the AC mains supply. The voltage

setting may be adjusted to local conditions. The frequency (50 or 60 Hz depending on

model), however, must match your supply. Check the settings printed on the label near the

mains input. See page 13 to change the voltage setting if necessary.

Releasing the Pan/Tilt Lock

The pan/tilt assembly (9) floats in a special rubber mount to reduce noise when operating

the pan and tilt motors. In order to protect the pan/tilt assembly from damage during ship-

ment, it is secured with two plastic straps and a locking thumbscrew. These must be

removed before using the RoboScan!

It is strongly recommended that the pan/tilt assembly be locked for transportation by replac-

ing the thumbscrew in position A over the pan/tilt assembly.

1. Cut and remove the two plastic straps.

2. Remove the thumbscrew over the pan/tilt assembly and store it in the

threaded hole, labelled B, on the pan/tilt plate.

3. Carefully remove the surface protection foil and warning notice from the

mirror.

Installing the Mounting Bracket

Use the 11 mm hole in the center of the mounting bracket to fasten a clamp (not included),

or to permanently bolt the fixture in place, with a grade 8.8 (minimum) M10 bolt and lock

nut. For safety, verify that the structure can support at least 10 times the weight of all

installed fixtures, clamps, cables, auxiliary equipment, etc., and always use an approved

means of secondary attachment such as a safety cable to prevent falls.

The mounting bracket may also be used as a floor stand.

1. Insert the two black plastic hand wheels into the bracket holes.

2. Place a plastic spacer on each hand wheel, between the bracket and the

casing, and screw the hand wheels into the fixture.

3. Turn or tilt the RoboScan to the desired position and tighten the hand

wheels.

Setup for Controller Operation

Connect the Serial Link

The RoboScan 812 may be used with DMX and Martin protocol controllers. The RoboScan

812’s XLR connections are configured for Martin protocol controllers such as the 3032.

When connecting a RoboScan 812 to any DMX-standard device, you must swap pins 2 and

3 with a phase-reversing cable.

1. Connect the controller’s data output to the RoboScan 812’s input (2). If using

a Martin-standard controller, use a direct 3-pin to 3-pin cable such as the one

provided. If using a DMX controller, use a phase-reversing cable, either 3-pin

to 3-pin, or 5-pin to 3-pin, depending on the output of the controller.

2. Continue the link: connect the output (1) of the fixture closest to the con-

troller to the input of the next fixture. Use a direct cable when connecting

same-standard fixtures. Use a phase-reversing cable only when connect-

ing a DMX-standard fixture to a Martin fixture with pin 2 hot. Up to 32 fix-

tures may be connected on a serial link.

3. Insert a male 120 ΩXLR termination plug in the output of the last fixture

on the link. The termination plug is simply a 3-pin male XLR plug with a

120 Ω resistor soldered between pins 2 and 3. The termination plug is

required for error-free communication.

Set the Address

When using the RoboScan 812 with a controller, you must set the DIP-switch (3) to the start

channel, also known as the address, which is the first channel the controller uses to send

instructions to the RoboScan 812.

For independent control, each fixture must have its own address and control channels. Two

or more RoboScan 812s may have the same address; however, they will receive the same

instructions and behave identically.

8 RoboScan 812

Martin mode: The RoboScan 812 uses 1 channel to communicate with the controller. The

address may be any channel between 1 and 32.

DMX mode: The RoboScan 812 may be operated in tracking or vector mode; see the DMX

protocol for details. It uses 5 consecutive DMX channels in tracking mode and 7 consecu-

tive DMX channels in vector mode. The factory default is tracking mode. The address may

be any channel up to 508 within the controller’s range (506 if 7 channels are used).

Example: 4 RoboScans using tracking mode (5 channels) may be addressed as follows:

Use the following procedure to set a Martin or DMX address.

1. Select an available address within the controller’s range.

2. Look up the DIP-switch setting on page 19. You can also calculate it by

subtracting pin values until the total of the values equals the address.

Start with the highest pin value that can be subtracted and work down

until there is no remainder. The table below shows the pin values.

3. Set the DIP-switch (3) by flipping ON the pins found in step 2.

9Operation

section 3

OPERATION

Stand-Alone Operation

The RoboScan 812 may be operated without a controller in stand-alone mode. In this mode,

the fixture performs a random sequence that is triggered by the beat of the music or auto-

matically at a set speed. The DIP-switch must be set to the desired stand-alone mode before

applying power. Settings for the different modes are shown below.

1. With the fixture powered off, set the DIP-switch (3) for the desired mode.

Pins not listed must be switched off.

2. Apply power to the RoboScan 812 to run the sequence.

Controller Operation

Getting Started

The RoboScan 812 may be used with DMX-512 and Martin protocol controllers; it auto-

matically determines which protocol is in use. Protocol auto-detection can be reactivated if

necessary by switching on all ten DIP-switches and then resetting the address.

1. Connect the RoboScan 812 to the controller and set the address.

2. Switch on and configure the controller.

3. Apply power to the RoboScan. After a short reset procedure it will

respond to the controller.

Controllable Effects

Lamp

After switching on the RoboScan 812, the lamp remains off until a “lamp on” command is

sent from the controller. If using a Martin protocol controller, the lamp may also be turned

off via the controller. This feature is not implemented in the DMX protocol - to turn off the

lamp you must power off the fixture.

It's important to note that the lamp is a cold restrike type: it must be cold before striking is

possible. The lamp must cool for approximately 5 minutes before it can be turned on again.

Pan/Tilt

The moving mirror allows you to pan the beam 175° and tilt it 83°. Movement speed may

be adjusted with the controller fade time (DMX tracking mode and Martin controllers) or

on a separate channel (DMX vector mode).

Color Wheel

The RoboScan 812 has 13 positions on the color wheel: 11 with saturated dichroic colors,

open white, and blackout. The wheel can be positioned between 2 colors to split the beam.

The speed of the color and gobo wheels may be adjusted with the controller fade time

(DMX tracking mode and Martin controllers) or on a separate channel (DMX vector mode).

Selecting color strobe causes the color wheel to change between any 2 adjacent colors or

between white and black. The strobe speed is variable.

Gobos

The RoboScan 812 has 11 gobos on the gobo wheel plus open and blackout. Selecting gobo

strobe causes the gobo wheel to change between any 2 adjacent gobos or between full open

and black. The strobe speed is variable.

Random Sequence

The RoboScan 812 may be set to perform a preprogrammed sequence with automatic or

music trigger.

Focus

Focus may be adjusted manually from 1 meter to infinity by turning the threaded lens barrel

(7). Screwing the lens in increases the focus distance; screwing it out decreases the distance

at which the image is focused.
