sing the fixture, check that all power distribution equipment and cables are
in perfect condition, are rated for the current requirements of all connected
devices, and are of suitable type for the location (including water, pollution,
temperature and UV resistance).
The voltage and AC frequency of the power at the MAINS OUT socket are the
same as those applied at the MAINS IN socket.
Isolate the fixture from power immediately if any seal, cover, cable, or other
component is damaged, defective, deformed or showing signs of overheating. Do
not reapply power until repairs have been completed
Do not immerse the fixture in water or any other fluid. Do not install the fixture in a
location where flooding may occur.
Protection from burns and fire
Do not operate the fixture if the ambient temperature (Ta) exceeds 40° C (104° F).
The surface of the fixture can reach up to 55° C (131° F) if the fixture is operated at
the maximum permitted ambient temperature. Allow the fixture to cool for at least 5
minutes before handling.
Install the fixture on a non-combustible surface (brick, concrete, plaster etc.) only.
Do not aim the fixture towards combustible materials (fabric, wood, paper etc.) that
are within 50 cm (19 in.) of the fixture.
Keep the fixture well away from flammable materials (volatile liquids etc.).
Do not expose the front glass to sunlight or any other strong light source from any

Do not attempt to bypass thermostatic switches or fuses.
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 accessories approved by Martin to
modify the light beam.
Protection from eye injury
Do not look directly into the product’s light output.
Do not look at operating light source. Eye injury may result.
Do not look at the light output with magnifiers, telescopes, binoculars or similar
optical instruments that may concentrate the light output.
Ensure that persons are not looking directly into the front of the fixture when the
product lights up suddenly. This can happen when power is applied, when the
product receives a DMX signal, or when certain control menu items are selected.
To minimize the risk of eye irritation or injury, disconnect the fixture from power at
all times when the fixture is not in use and provide well-lit conditions to reduce the
pupil diameter of anyone working on or near the fixture.
This fixture corresponds to Risk Group 3 according to EN 62471 when all
photobiological risks are considered and Risk Group 2 product according to
IEC/TR 62778 for blue light only. It emits possibly hazardous optical radiation. It
falls into the Risk Group categories shown below according to both EN 62471 and
IEC/TR 62778 under worst-case conditions.
At a distance of less than 5.8 m (19 ft.) from the fixture, the light output can
potentially cause eye or skin injury before an exposed person's natural aversion
responses (blink reflex and reaction to skin discomfort) can protect them. At
distances greater than 5.8 m (19 ft.), potential eye and skin injury hazards from the
light output are normally prevented by natural aversion reflexes.
Position the fixture so that persons cannot be exposed to the fixture's light output
at a distance of less than 5.8 m (19 ft.) from the fixture, and so that prolonged
staring into the light output at less than 23 m (75.5 ft.) from the fixture is not
expected.
Protection from injury
Fasten the fixture securely to a fixed surface or structure when in use. The fixture
is not portable when installed.
Ensure that all supporting structures, surfaces, fasteners and lifting equipment can
bear the weight of all the devices they are intended to support plus an adequate
safety margin, and that they conform to local building and safety regulations.
If the fixture is installed in a location where it may cause injury or damage if it falls,
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 that it secures. The safety cable must comply with EN 60598-2-17 Section
17.6.6 or BGV C1 / DGUV 17, and must be capable of bearing a static suspended

Page 8
load at least six times (or more if required by locally applicable regulations) the
weight that it secures.
Eliminate as much slack as possible in the safety cable (by looping it more than
once around the rigging truss, for example). Make sure that, if the primary
attachment fails, the fixture cannot fall more than 20 cm (8 inches) maximum
before the safety cable catches it.
If the safety cable attachment point becomes deformed, do not suspend the fixture.
Have the fixture repaired by an authorized Martin service partner.
Ensure that any accessories such as gel frames, gobo holders are securely
fastened.
Block access below the work area and work from a stable platform whenever
installing, setting, adjusting, or cleaning the fixture.
Do not operate the fixture with missing or damaged covers, shields or any optical
component.
If an operating problem occurs, stop using the fixture immediately and disconnect it
from power. Do not attempt to use a fixture that is obviously damaged.

mains power input cable supplied with the
fixture is rated 6 A and can supply only one fixture with mains power. Do not
connect any device to the fixture’s MAINS OUT socket when using this input
cable. If you want to connect other fixtures to the MAINS OUT socket, see
‘Linking fixtures to power in a chain’ below.
For protection from electric shock, the fixture must be grounded (earthed). The
power distribution circuit must be equipped with a fuse or circuit breaker and
ground-fault (earth-fault) protection.
Important! Do not use an external dimming system to supply power to the fixture, as this may
cause damage to the fixture that is not covered by the product warranty.
The fixture has an auto-ranging power supply that accepts AC mains power at 100-240 V at 50/60
Hz. Do not apply AC mains power at any other voltage or frequency to the fixture.
The fixture can be hard-wired to a building electrical installation if you want to install it
permanently, or a power plug (not supplied) that is suitable for the local power outlets can be
installed on the power cable. Socket outlets or external power switches used to supply the fixture
with power must be located near the fixture and easily accessible so that the fixture can easily be
disconnected from power.
If you install a power plug on the supplied power cable, install a grounding type (earthed) plug with
integral cable grip that is suitable for your local mains voltage and is rated minimum 6 A. Follow
the plug manufacturer’s instructions and connect the wires in the power cable as shown in this

Linking fixtures to power in a chain
The mains power input cable supplied with the fixture is rated 6 A and can safely supply power to
one fixture only.
If you want to use the MAINS OUT socket on the fixture to link power to another fixture in a daisychain, you must first replace the supplied power input cable with one of the 16 amp rated 12 AWG
/ 2.5 mm
page 36). If you install a power plug on a 12 AWG / 2.5 mm
type (earthed) plug with integral cable grip that is rated minimum 16 A, 250 V.
To link fixtures to power in a daisy-chain, use the 16 amp rated 12 AWG / 2.5 mm
cables available from Martin (see ‘Accessories’ on page 36) to link fixtures’ MAINS OUT sockets to
MAINS IN sockets. Using the 16 amp rated cables available as accessories from Martin, you can

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 a DMX buffer is recommended for longer runs. The pin-out
on all connectors is:
•pin 1 = shield
•pin 2 =
•pin 3 = hot (+).
Pins 4 an
additional data signals as required by the DMX512-A standard. Standard pin-out is pin 4 = data 2
cold (-) and pin 5 = data 2 hot (+).
To split the link into branches, use an opto-isolated splitter such as the Martin RDM 5.5 Splitter.
Terminate the link by installing a termination plug in the output socket of the last fixture. The
termination plug, which is a male XLR plug with a 120 Ohm, 0.25 W resistor soldered between
pins 2 and 3, “soaks up” the control signal so it does not reflect and cause interference. If a splitter
is used, terminate each branch of the link.

If you need to focus the fixture but there is nobody to operate the lighting console, you can quickly
turn the fixture on in “Fast Focus mode” using the control panel. Hold down the ENTER button for
5 seconds and the fixture will come on at full brightness in open white for 60 seconds, allowing you
to set the focus. After 60 seconds the fixture will return to normal operation.
Setting the DMX address
Each fixture must be assigned a DMX address. The DMX address, also known as the start
channel, is the first channel used to receive instructions from a DMX controller. The fixture is
controlled using between 1 and 17 DMX channels depending on the personality set. If a fixture
using 17 channels has a DMX address of 1, then it uses channels 1 to 17 inclusive. The following
fixture in the DMX chain can then be set to a DMX address of 18.
16 Martin® ELP CL User Manual
Page 17
For independent control, each fixture must be assigned its own control channels. Two fixtures of
the same type may share the same address if identical behavior is desired. Address sharing can
be useful for diagnostic purposes and symmetric control.
To set the fixture’s DMX address:
1. Enter the control menu and select DMX SETUP. Press ENTER.
2. Select DMX ADDRESS and press ENTER.
3. Use the UP and DOWN buttons to select the desired address setting.
4. Press ENTER to confirm your selection (or to return to the top-level menu without changing the
settings, press the MENU button).
Setting DMX personality
DMX personality sets how many control channels are used. There are 3 personalities to choose
from:
•1 channel – dimmer only
•10 channel – 8-bit dimmer with 8-bit control of functions (default)
•17 channel – 16-bit dimmer with 16-bit control of functions
The commands available on each channel are described in the section “DMX protocol” on page
27.
To set the DMX personality:
1. Enter the control menu and select DMX SETUP. Press ENTER.
2. Select DMX MODE and press ENTER.
3. Use the UP and DOWN buttons to select 1, 10 or 17.
4. Press ENTER to confirm your selection (or to return to the top-level menu without changing the
settings, press the MENU button).

O
The PERSONALITY menu allows you to set other options for the fixture.
Stand-alone mode
The fixture can operate in stand-alone mode allowing control of multiple fixtures from a single
host fixture if no DMX console is connected. The options are OFF (default), HOST and
CLIENT. Stand-alone operation will be automatically overridden by incoming DMX signal.
Light quality
The ELP offers two options in the QUALITY menu that let you prioritize either color rendering or
power in the fixture’s light output. The settings available are:
•HIGH QUALITY mode: CRI = 90, color temperature = 6000 K, max. output = 5600 lumens, or
•HIGH OUTPUT mode: CRI = 85, color temperature = 5500 K, max. output = 6900 lumens.
The QUALITY menu also includes a TUNGSTEN setting in which the fixture color temperature
emulates the warm output from a fixture with a tungsten lamp: the color temperature is set to
3000 K and becomes warmer at lower intensity levels.
Besides the TUNGSTEN setting, you can also enter a custom color temperature from 2000 K to
10 000 K.
in 1-Channel DMX Mode, the TUNGSTEN and custom color temperature settings determine the
color temperature of the fixture’s white light output.
In 10-Channel and 17-Channel Modes these settings also determine the base color temperature of
the fixture’s white light output. In these modes you can use color mixing on top of this color
temperature.

Setting a sequence of scenes
The SHOW menu allows the fixture to store up to 20 scenes internally and display them in a timed
sequence.
SET SCENE TOTALS sets how many scenes will be in the sequence, from 1 to 20.
To store scenes, select EDIT SCENE COLOR and press ENTER. Then use the UP and DOWN
buttons to select the scene number to be edited. Press ENTER. Use the UP and DOWN buttons to
select the color to be set (RED, GREEN, BLUE, LIME, AMBER), then press ENTER and finally
use the UP and DOWN buttons to set the brightness of the color.
The FADE TIME option sets the fade time between scenes, from 0-120 seconds (default 3
seconds).
The HOLD TIME option sets the time each scene is shown for, from 0-600 seconds (default 3
seconds).
Color calibration
From the SERVICE menu you can select CALIBRATION. This menu allows you to adjust the
overall brightness and individual colors of the fixture to match with other fixtures. The fixture is
calibrated in the factory but over time the brightness of the LED emitters will gradually decrease,
so this function can be useful if you need to match a new fixture with older ones.
•DIMMER sets the overall maximum brightness of the fixture.
•RED, GREEN, BLUE, LIME, AMBER can be made dimmer or brighter from -128
•LOAD
Because two light quality modes – high-quality and high-output mode – are available in the
PERSONALITY QUALITY menu, from software v.1.2 you can adjust the calibration settings of
each mode separately:
•DEF HQ SET replaces the factory-set calibration values for high-quality mode with the curre
•DEF HO SET replaces the factory-set calibration values for high-output mode with the curre
You must enter a password (019 by default) before you can access these two menu items.
Important! The DEF HQ SET and DEF HO SET commands permanently overwrite the factory-set
calibration values. It is not possible to restore the factory-set values by powering the fixture off and
on, resetting the fixture or uploading new firmware. Once you have saved custom calibration
values using DEF HQ SET and DEF HO SET commands, the only way to return to the original
factory-set values is to re-adjust the calibration settings for the dimmer and the individual colors
back to their original values..
DEFAULTS will load the factory-set calibration values. If you have replaced the factoryset values with custom values using DEF HQ SET or DEF HO SET (see below) it

Setting options by RDM
You can remotely configure the fixture over the DMX line using a suitable RDM-compatible
controller that is connected to the installation via a DMX data link.
A full list of the RDM functions that the ELP fixture supports is given at the end of this chapter.
These functions are generally referred to using the more specific term ‘PIDs’ or ‘Parameter IDs’.
Scanning for RDM devices on the data link
Before you can communicate with fixtures using RDM, you must send a scan command (also
called a device discovery command) to all the devices on the data link so that the RDM controller
can identify them. It does this by retrieving each device’s factory-set unique identifier (UID). This
process can take some time depending on the number of devices on the link.
Getting status and setting options by RDM
The status and options listed in the table below can be read and set by RDM.
You can set an option on one fixture by sending a unicast RDM command to that one fixture only,
or you can set the same option on all the fixtures on the data link by sending a broadcast RDM
command to all the devices on the link.
For status reading, you can only use unicast RDM to read information from an individual fixture.

As a minimum, the ELP CL supports the following RDM functions:

Effects
This section describes the effects provided by the ELP CL. See ‘DMX protocol’ on page 27 for a
full list of the DMX channels and values required to control the different effects.
In 17Ch DMX control mode, all intensity controls are 16-bit. In 10Ch mode all controls are 8-bit.
Dimming
Overall intensity can be precisely adjusted from 0 to 100% using 16-bit coarse and fine control. In
10Ch mode the control is 8-bit. In 1Ch mode this is the only control and the fixture is fixed in white.
Strobe effects
An electronic shutter provides instant open and blackout, random and variable speed flash from 1
to 12 flashes per second, and pulse effects.
CTC
The color temperature of the fixture can be set from 2000K to 10000K using 16-bit coarse and fine
control. When the CTC function is active, the color control channels are not used.
Color mix
The fixture is equipped with Red, Green, Blue, Lime and Amber emitters which can be individually
controlled using 16-bit coarse and fine control.
Color Scene
You can select from a range of fixed color temperatures and LEE color filters. If the Color Scene
function is active the Color mix channels are not used.
Manual focus
The ELP CL has a unique “Fine Focus” system which allows you to easily make small focus
adjustments using a gear-based wheel on top of the lens tube. To focus the fixture, see drawings
below. Loosen the thumbscrews A and B on the top and bottom of the lens tube slightly, then turn
the focus wheel C to slide the lens in or out of the tube. Tighten the thumbscrews A and B again to
hold the focus setting.

Manual beam shaping shutters
The fixture has 4 manually operated beam shaping shutters.
To change the shape of the beam, power the fixture on and aim the beam at the target. Use the
four shutter blade handles (see 6 in ‘Fixture overview’ on page 10) to adjust the position of the
shutter blades and obtain the desired beam shape.
Martin® ELP CL User Manual 23

Use of filters
The color filter frame that is supplied with the lens tube lets you add color correction or diffusion
filters to the front of the fixture. Push the filter retaining clip (see 1 in ‘Fixture overview’ on page 10)
to one side to insert and remove filters. Click the retaining clip back into place after inserting a filter
and check that the clip is secure to prevent the color filter frame from falling out.
Use of gobos and irises
The fixture will accept an A-size or B-size goboholder or an iris (items not included) in the
gobo/accessory gate. There is a sliding cover over the gate to prevent light spill and retain the
goboholder in the fixture. To install a goboholder or iris:
1. Allow the fixture to cool. See drawing below. Loosen, but do not remove, the two thumbscrews
(arrowed) at the sides of the cover.
2. Slide the cover towards the front of the fixture.
3. Slide the goboholder into the accessory gate in the fixture.
4. Slide the cover back so that it holds the goboholder in place and tighten the thumbscrews.
