Pilota 1200 utilses a Philips MSR 1200 SA lamp rated at 1200W with a GY 22 lamp base.
The lamp is available from your authorised coemar sales agent:
coemar cod. 105090/1
power 1200 w
luminous flux 96.000 lm
colour temperature 6500° K
lampbase GY 22
approximate lamp life 500 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.
MSR lamps are part of the mercury vapour family of discharge lamps and must be handled with great care. The lamp opera-
tes at hight pressure, and the slight risk of explosion of the lamp exists if operated over their recommended life.
installing the lamp
1) Using a suitable screwdriver remove the two screws (D) which affix the lamp assembly unit of the fixture, located towards
the rear.
2) Remove the lamp assembly.
3) Locate the GY 22 lampholder.
4) Insert the lamp. The lamp used is manufactured from quartz
glass and should be handled with care; always adhere to the
instructions supplied in the packaging. Never touch the glass
directly, use the tissue provided in the lamp’s packaging.The GY
22 lampbase is asymmetrical in construction so the lamp may be
positioned easily. Insert the lamps into the lampholders. DO NOT
USE UNDUE FORCE. In case of difficulty, simply rotate the lamps
and repeat the procedure.
5) Reposition the lamp assembly and replace the two screws (D) removed previously.
Attention!
Remove mains power prior to opening up the unit.

Attention: DO NOT use the projector without first undertaking the realignment of the lamp in the optical train. This ensures
that no internal parts are overheated due to incorrect focusing. Refer to section 13 of this manual for instructions regarding
lamp alignment.
Pilota 1200 is fitted with an electronic ballast which stabilises the output voltage to the lamp for any input voltage from
200 to 260V; it therefore requires no modifications to operate within this range of input voltages.
Attention! Should you wish to operate at voltages of 115 V, it is necessary to stipulate this at the time of ordering.

mounting
Please read all the following information prior to using the pilota 1200.
lamp
The output of the lamp is a direct function of the position of the arc within the optical system. If the arc is not properly cen-
tred within the optics, the beam will appear dull or with a noticeable hot spot. Additionally, the iris diaphragm and dimmer
will not work effectively. Refer to section 13 of this manual for instructions on aligning the lamp within the optical train cor-
rectly.
risk of fire
Every fixture produces head, and should therefore be installed in a well-ventilated position. The minimum distance from
flammable materials: 0,5 m. The minimum distance from the object being illuminated: 2 m.
protection against liquids
The projector contains electric and electronic components that must not come into contact with water, oil, or any liquid.
installing on a stand
pilota 1200 is supplied with a spigot allowing the followspot to be
installed easily on a followspot stand. The horizontal movement
(left/right) is governed by the positioning the yoke of the fixture on the
spigot and we recommend the use of the coemar (cod. 8002) follow-
spot stand, which utilises a neoprene collar to allow smooth panning.
Prior to installing the pilota 1200 on the stand, it is iimportant to
ensure that the legs of the stand are completely apart and located on a
stable, level surface. Lift the extension tube of the stand to the desired
height and lock it off in position. The spigot may be installed into the
tube and then the followspot placed and secured into position.
balancing
coemar adjusts the position of the yoke on the body of the followspot
into the position which best balances the followspot when mounted on
its stand. The centre of balance of the pilota 1200 may vary when a
colour change device is mounted to the front of the unit. To rebalance
the unit, make sure first that projector is sitting horizontally in the stand
and loosen the the handles located on the sides of the yoke which will
allow it to tilt up and down. Gradually loosen the two hex-head screws
located on the sides of the yoke which fix the yoke to the followspot
body until the followspot is able to slide easily along its tracks. Slide the
body into the position which best balances the unit.
When this is done, firmly tighten the two hex screws.
manoeuvering the followspot
To operate the followspot in a smooth manner, loosen the gradually loosen the two handles indicated in the diagram
below; A for vertical tilt movement, B and C for horizontal panning.

cable preparation
The mains cable provided is thermally resistant, complying to the most recent international standards.
NB: In case of cable replacement, similar cable with comparable thermal resistant qualities must be used exclusively (cable
3x1,5 ø external 10 mm, rated 300/500V, tested to 2KV, operating temperature -40° +180°).
mains connection
Pilota 1200 is fitted with an electronic ballast which stabilises the output voltage to the lamp for any input voltage from
180 to 260V; it therefore requires no modifications to operate within this range of input voltages.
Should you wish to operate at voltages of 115 V, it is necessary to stipulate this at the time of ordering.
Prior to connecting the unit to your mains supply, ensure that the model in your possession correctly matches the mains
supply available to you.
For connection purposes, ensure your plug is of a suitable rating: 9.5 amps.
Locate the mains cable which exits the unit and connect as shown below:
protection
The use of a thermal magnetic circuit breaker is recommended for each Pilota 1200.
A good earth connection is essential for the correct operation of the fixture. Strict adherence to regulatory norms is strongly
recommended.
ATTENTION!, DANGER!
The electronic ballast with which the Pilota 1200 is equiped, as with other electronic devices, requires that the neutral
cable be of correct size to ensure correct balancing of the load with the active.
Please ensure that proper consideration has been given to this point when connecting the fixture to mains power.
Pilota 1200 requires a good earth connection to operate properly.
Do not operate the unit unless the green/yellow earth cable is correctly fitted.

After having followed the preceding steps, turn on the mains to the followspot, and then turn on the power switch. The
followspot should be turned on with the standby switch in the off position.
standby switch 50%
The standby 50% switch allows the power output to be reduced to 50% of maximum output.
During periods of time when the followspot is not required in a production, we recommend switching the standby switch
to on, thereby reducing the internal temperature of the followspot and prolonging the working life of the internal compo-
nentry.
During a short pause in a show when you may not wish to shut off the lamp entirely, shut down the dimmer, open up the
iris diaphragm (if installed) and set the switch to standby. Set the switch to full on just prior to re-using the followspot in your
show. The pilota 1200 will silently power up to maximum output immediately. The cooling fan is powered directly from
the ballast, and so will operate from the moment the ballast is powered up. It is advisable to keep the fan on for a short time
after the lamp has been switched off in order to cool the unit effectivelly.

focusing and zoom
pilota 1200 utilises high definition lenses which allow zoom adjustment and focusing. These two functions are operated
simply by sliding the two adjusters located on the right of the followspot body longitudinaly along the body until the requi-
red zoom angle and focus is achieved. Lock off the position of the lenses by turning the knobs in the clockwise direction.
dimmer
Via the dimmer located in the pilota
1200 it is possible to smoothly dim down
the output of the followspot, with no loss
in colour temperature, from maximum out-
put to blackout. The function is operated
via the knob located on the side of the fol-
lowspot,: turn it in a clockwise direction to
open up the dimmer to allow maximum
output or turn it in an counter-clockwise
direction to gradually dim down the out-
put to full blackout.
iris diaphragm
The iris diaphragm is supplied with the unit but not installed. It is installed by simply sliding it into the guide located between
the optics of the unit and the lamp assembly and operated via the handle provided with the unit.
The iris diaphragm reduces the diameter of the beam
without affecting the intensity of the output. The long hand-
le allows easy access to operate the unit from either side of
the followspot.
9. Operating

framing shutters
4 framing shutters are included in the packaging. These are inserted in the appropriate slots located, as shown in the pic-
ture below, between the optics of the unit and the lamp assembly. The use of these shutters allows the output to be in the
form of a variety of geometric shapes.
internal colour changer The internal colour changer of the pilota 1200 contains 6 colours, a
release-colour function and a colour correction filter.
The internally-illuminated selection buttons allow the correct button to
be easily selected and identified even in poorly-lit environments.
The conversion filter is located on the second button and may be
selected in tandem with any other colour. It will not be released by
the release-colour function.
installing accessories
If required, an external colour filter frame or an external colour change unit may be utilised. These accessories are fitted to
the front of the pilota 1200.When installing either of these accessories, make sure that it is correctly installed and held in
place by the retaining spring.
Also available is a followspot stand (benny version cod.8002) specifically designed for the pilota 1200.
colour changer and colour filter frame
coemar manufactures both an external colour changer and a colour filter frame which fit to the front of the pilota 1200.
If you intend installing the colour changer, you may wish to re-balance the unit.
colour filter frame
The colour filter frame allows the insertion of a sheet of colour filter of dimensions 150mm X 120 mm.
We recommend the use of high quality, high temperature colour filter such as Rosco SuperGel.
rebalancing
The installation of the external colour changer may alter the balance of the followspot. To correct any imbalance, refer to the
instructions located in section 6 of this instruction manual.

Aligning the lamp in the optical system is achieved via the 3 adjusters at the rear of the projector. This procedure should be
undertaken to properly align the lamp in the optical system and to avoid the possible overheating of the internal compo-
nents due to the incorrect focusing of the beam onto components not intended to be exposed to this.
alignment procedure
To adjust the lamp, turn on the followspot and allow the lamp to reach maximum intensity (approximately 2 minutes).
Direct the beam onto a flat surface some 8 to 10 metres from the followspot. Slide the focus knob forwards so that the
beam is totally out of focus. Close down the iris diaphragm to at least half size. The arc of the lamp will appear as a single
line and should be at the centre of the beam. Should this not be the case, adjust the lamp position.
Adjustment is effected using a screwdriver and the three adjusters A, Band Cin conjunctino with each other; with the
lamp on, blackout and dimmer fully open, and no filters inserted in the beam.
If the lamp is not correctly aligned, a hot-spot will be noticeable. This is a function of the lamp’s positioning. Use the two
adjusters (Band C) to bring the hot-spot to the centre of the beam. Use the third adjuster (A) to flatten the beam to maxi-
mum uniformity.
vertical adjustment
Adjuster (C) acts on a lever and spring assembly to position the lamp via a vertical movement within the reflector; rotate it
until correct positioning is achieved.
horizontal adjustment
Adjuster (B) acts on a lever and spring assembly to position the lamp via a horizontal movement within the reflector; rotate it
until correct positioning is achieved.
axial adjustment
Adjuster (A) moves the entire lamp axially within the unit; rotate it until correct positioning is achieved; resulting in an even,
flat beam.

Whilst every possible precaution has been taken to ensure the trouble-free operation of your Pilota 1200, the following
periodic maintenance is highly recommended.
Opening the lamp housing
It is possible to open the rear of the followspot in the area which houses
the lamp assembly using a Philips head screwdriver and undoing the
screw at the rear of the housing. When this has been done, lift the hou-
sing cover off.
After this simple operation, you will have direct access to the lamp assembly to perform any necessary maintenance.
Opening the optics housing
To access the optics section of the Pilota 1200 in order to perform
normal maintenance routines, simply slide back the doors at the bot-
tom of the followspot housing, as shown in the diagram.
When this is done, the user will have complete access to the optic
group within the followspot.
Fuse replacement
Locate the fuse, which protects the lamp and electronics, in the ballast at the base of the followspot yoke.
Using a multimeter, test the condition of the fuse, replacing it with one of equivalent type if necessary.
periodic cleaning
lenses and reflectors
Even a fine layer of dust can reduce the luminous output substantially. Regularly clean all lenses and the reflector using a
soft cotton cloth, dampened with a specialist lens cleaning solution.
fans and air passages
The fans and air passages must be cleaned approximately every 6 weeks; the period for this periodic cleaning will depend,
of course, upon the conditions in which the projector is operating. Suitable instruments for performing this type of mainte-
nance are a brush and a common vacuum cleaner or an air compressor.
periodic maintanance
lamp
The lamp should be replaced if there is any observable damage or deformation due to heat. This will avoid the danger of
the lamp exploding.
mechanicals
Periodically check all mechanical devices for wear and tear, replacing them if necessary. Periodically check the lubrication of
all components, particularly the parts subject to high temperatures. If necessary, lubricate with suitable lubricant, available
from your coemar distributor.
electrical components
Check all electrical components for correct earthing and proper attachment of all connectors, refastening if necessary.
Attention
Disconnect mains power prior to removing the projector housing.
