3.Important Fire prevention:
safety information 1. CF ZOOM AL utilises a Philips Fabolux 500W 55v; the use of any alternative
lamp is not recommended and will null and void the fixture’s warranty.
2. Never locate the fixture on any flammable surface.
3. Minimum distance from flammable materials: 0,5 m.
4. Minimum distance from the closest illuminable surface: 2 m.
5. Replace any blown or damaged fuses only with those of identical values. Refer to
the schematic diagram if there is any doubt.
6. Connect the projector to mains power via a thermal magnetic circuit breaker.
Prevention of electric shock:
1. High voltage is present in the internals of the unit. Isolate the projector from
mains supply prior to performing any function which involves touching the inter-
nals of the unit, including lamp replacement.
2. For mains connection, adhere strictly to the guidelines outlined in section 7 of this
manual.
3. The level of technology inherent in the CF ZOOM AL requires the use of specia-
lised personnel for all service applications; refer all work to your authorised coe-
mar service centre.
4. A good earth connection is essential for proper functioning of the projector.
Never operate the unit without proper earth connection.
5. The fixture should never be located in an exposed position, or in areas of extreme
humidity. A steady supply of circulating air is essential.
Safety:
1. The projector should alwasy be installed with bolts, clamps, and other fixings
which are suitably rated to support te weight of the unit.
2. Always use a secondary safety chaing of a suitable rating to sustain the weight of
the unit in case of the failure of the primary fixing point.
3. The external surface of the unit, at various points, may exceed 150°C. Never hand-
le the unit until at least 10 minutes have elapsed since the lamp was turned off.
4. Always replace the lamp if any phusical damage is evident.
5. Never install the fixture in an enclosed area lacking sufficient air flow; the ambient
temperature should not exceed 35°C.
6. A hot lamp may explode. always wait for at least 10 minutes to elapse after the
unit has been turned off prior to attempting to replace the lamp.
Always wear suitable hand protection when handling the lamp.

4. Lamp: Installation CF ZOOM AL utilises a Philips Fabolux 500W 55V lamp with a
and replacement GX 9,5 lampbase
The lamp is available from your authorised coemar sales agent:
coemar cod. 105071
wattage 500 W
luminous flux 11.880lm
colour temperature 3200° K
base GX 9,5
approximate life 200 hours
The fixture’s internal temperature can reach 250° C after 5 minutes, with a maximum
peak of 350° C; ensure that the lamp is cold prior to attempting removal. The fixture
should be allowed to stand and cool for 10 minutes prior to its removal.
The lamp is part of the tungsten halogen family of incandescent lamps and must be
handled with great care. The lamp operates at high temperature, and the slight risk
of explosion of the lamp exists if operated over its recommended life of 200 hours.
We recommend, therefore, that the lamp be replaced within the manufacturer’s spe-
cified lamp life.
mounting the lamp
1) Using a 3mm hex (Allen) key, remove the two hex bolts (A) which affix the lamp
assembly to the rear of the projector.
2) Remove the lamp assembly (B).
Attention
Turn off the power prior to opening up the unit.

3) Locate the lampholder (C)
4) The GX 9,5 lampholder is symmetrical in construction; the lamp used is manufac-
tured from quartz glass and should be handled with care; always adhere to the
instructions supplied in the lamp’s packaging. Never touch the glass directly, use
the tissue provided in the lamp’s packaging.
Insert the lamp (D) into the lampholder (C). DO NOT USE UNDUE FORCE. In case
of difficulty, re-read the instructions and repeat the procedure.
5) Replace the lamp assembly (B) into its original position and replace and tighten
the two screws (A) which were previously removed.
Attention: we recommend that the lamp be realigned in the optical train of the unit
to avoid overheating of the dichroic filters and other internal components of the
unit. refer to section 13 for instructions about this procedure.

5. Operating voltage and coemar factory presets (barring specific requests), a voltage of 230v and 240v
frequency selectable via the switch on the base of the CF ZOOM AL.
Remember to switch the selector (230 or 240V) to the position which best matches
the average voltage available at your particular venue. The following diagrams show
the transformer settings as set by coemar.
If your required operating voltage is 208V, you may select this internally within the
unit by moving the cables numbered 20 and 18 (currently connected in the 240V
position) or the cables numbered 19 and 17 (currently connected in the 230V posi-
tion), thereby no longer availing yourself of either the 230V or 240V option.

6. Mounting the unit mounting
The CF ZOOM AL may be either floor or ceiling mounted.
The structure from which the unit is hung should be of sufficient rating to hold the
weight of the unit, as should any clamps used to hang the unit.
The structure should also be sufficiently rigid so as not to move or shake whilst the
CF ZOOM AL moves during its operation.
The mounting holes in the base of the unit allow it to be mounted at various angles
to the mounting truss and to trusses of various dimensions.
The following is a diagram outlining the base of the CF ZOOM AL.
Note that in order to take advantage of the full articulated movement of the projec-
tor, it should be installed with the label marked ” Lato frontale/ Front” facing towards
the main item to be illuminated; in this manner the “0” or “home” position of the CF
ZOOM AL will be in the most efficient position.

protection against liquids
The projector contains electric and electronic components that must not come into
contact with water, oil, or any other liquid.
movement
The projector has a movement of 370° in the base and 280° in the yoke; DO NOT
place any obstructions in the path of the projector’s movement.
safety chain
The use of a safety chain (cod. 069) - fixed to the CF ZOOM AL and to the primary
suspension point, is highly recommended to protect against accidental failure,
however unlikely, of the primary suspension point.
If using an after-market safety chain not manufactured by coemar, ensure that it is
of sufficient rating to hold the weight of the fixture.
risk of fire
Each fixture produces heat and must be installed in a well-ventilated position. The
minimum recommended distance from flammable material is: 0.5m. Minimum
distance from the object being illuminated is: 2 m.

Mains connection cabling
The mains cable provided is thermally resistant, complying to the most recent
international standards. It meets or exceeds the VDE and IEC norms, IEC 331,
IEC 332 3C,CEI 20 35.
NB: In case of cable replacement, similar cable with comparable thermal resistant quali-
ties must be used exclusivelly (cable 3x1.5 ø external 10 mm, rated 300/500V, tested
to 2KV, operating temperature -40° +180°, coemar cod. CV5309).
mains connection
The CF ZOOM AL can operate at voltages from 208V-230V-240V at 50 or 60Hz
(operating voltage and frequency can be selected as described in section 5 of this
manual).
Prior to connecting the unit to your mains supply, ensure that the model in your pos-
session correctly matches the mains supply available to you.
For connection purposes, ensure your plug is of a suitable rating: 3,5 amps.
Locate the mains cable which exits the base of the unit and connect as shown
below:
protection
The use of a thermal magnetic circuit breaker is recommended for each CF ZOOM AL.
A good earth connection is essential for the correct operation of the fixture. Strict
adherance to regulatory norms is strongly recommended.

9. Powering up After having followed the preceding steps, turn on the DMX 512 controller which
will be used to control the CF ZOOM AL. Following this, turn on the power to the
projector, and turn on the projector’s power switch.The projector will perform
a reset function on all the internal and external motors. This will last
some few seconds, after which it will be subject to the external signal
from the controller.
DMX led
The DMX led will be static on to indicate that DMX 512 signal is being correctly
received by the projector.
If the led is off, the projector is not receiving signal. check the cabling and the func-
tioning of the controller.

10. DMX addressing Each CF ZOOM AL utilises 13 channels of DMX 512 signal for complete control.
To ensure that each projector accesses the correct signal, it is necessary to correctly
address each fixture. Any number between 1 and 495 can be generated via the mul-
tifunction panel of the CF ZOOM AL.
This procedure myst be carried out on every CF ZOOM AL. being used
When powered up initially, each projector will show A001 which indicates DMX
address 1; a projector thus addressed will respond to commands on channels 1to
13 from the DMX 512 controller. A second projector should be addressed as
14, a third as 27 and so on until the final CF ZOOM AL has been addressed.
Altering DMX addresses
1) Press the +or –button until the display shows the DMX required, the characters
in the display panel will flash to indicate that the selection is not stored in memory.
2) Press the enter button to confirm your selection; the display will stop flashing
and the projector will now respond to the new DMX address.
3) To better understand the function of each channel, we refer you to section 12
“Control channel functions from a DMX 512 controller”.
Important Note: Keeping the +or –button pressed will cause the display to alter
at increased speed, allowing a faster selection to be effected.
By pressing the –button, you may inadvertently select a DMX address which is not
being communicated to the fixture by the controller, for example 500. If this is the
case, the display will slow the data reception, (since it does not exist), and you will note
that it is slow to respond to your commands (for example altering an address or reque-
sting or confirming a reset). You may solve this problem by either sengin data to this
address, or by altering the incorrect DMX setting of the CF ZOOM AL in question.
