Setting up the unit
To activate the unit, connect the included power supply to the unit and a suitable 230V, 50 Hz power
outlet. The unit will activate directly after it is plugged in to a wall outlet or other power source.
Give the movinghead time to calibrate the stepping motors, which are used to determine the position
of the head. You may hear and see some shaking, which is normal. The stepping motors use an end
point to determine the beginning and end of their movement. The displays shows a scrolling “SETUP
U2” status. After calibration, the movinghead will start the previously used mode, but by default it is set
to DMX mode.
The status of the movinghead is shown on the display (which
automatically shuts off after a few seconds of inactivity). The shown
values determine the current status and can be changed by
pressing the buttons on the control panel. The four buttons each
have their own function, for easy navigation.
Press the ‘MODE/ESC’ button to switch modes, so you can easily
select the built-in automatic, music controlled or DMX mode.
DMX mode
After calibration the display shows ‘ D001’, which indicates that the unit is currently on DMX-mode,
with DMX-channel 1 as the starting address. A small LED next to the last digit states wheter the unit is
receiving DMX.
Changing the DMX starting address is done by pressing the ‘up’ and ‘down’ buttons on the control
panel. You can select a value between 1 and 512.
The ERO 540 has two DMX modes, one for basic control (5 channels), the other for extended control
(13 channels).

Automatic mode:
Select the automatic mode (fast or slow) when you wish to let the movinghead perform its own light
show. The slow mode provides slow movement and gobo/color change, while the fast mode is more
suitable for party-applications.
Press the ‘MODE/ESC’ button until the display shows ‘MASL’, to activate the slow automatic mode.
Press ‘ENTER’ to confirm, the display shows ‘SLOV’. Stop at the ‘MAFA’ mode to activate the fast
automatic mode. When confirmed with ‘ENTER’, the display shows ‘FAST’.
Music controlled mode:
Select this mode if you wish to have a music-synchronized light show. The unit has a built-in
microphone, which is used to ‘listen’ to the beat of the music. With every beat, a certain action is
taken. This may be movement, color change, gobo change or the activation of the strobe mode.
Press the ‘MODE/ESC’ button until the display shows ‘MStS’, to activate the sound active mode. Press
‘ENTER’ to confirm, the display shows ‘Srun’. When no music is detected, the unit will perform its own
slow lightshow until it detects music again.
Master/slave mode
It is possible to interconnect several ERO 540 fixtures to perform a synchronized lightshow, based on
automatic or music controlled actions. Connect the units with standard 3P XLR to XLR cables. The
first unit will be the master unit, sending its signal out to all slaves, which will follow its actions in a
synchronized way.
1. Setting the master unit:
Select ‘MAFA’ or ‘MASL’ (sound active) or the ‘MStS’ (automatic) mode on the first unit
When selecting ‘MAFA’, the display will show ‘FAST’ after confirmation (press Enter to confirm).
When selecting ‘MASL’, the display will show ‘SLOV’ after confirmation (press Enter to confirm).
When selecting ‘MStS’ , the display will show ‘Srun’ after confirmation (press Enter to confirm).
2. Setting the slave units:
The slave fixtures have to be set in slave-mode to mimic the actions of the master fixture. Select the
‘SLAV’ mode on each slave-fixture, ‘Son’ will be shown on the display after confirmation. When this
mode is active on the slave fixtures, the master/slave setup is complete.

Installation and maintenance
Mounting the bracket
On the bottom of the movinghead, there are two holes to mount the included bracket, using the
included bolts. It is possible to mount a G-clamp or halfcoupler to this bracket. It is also possible to
mount the bracket on a ceiling, wall, bar, floor, desk or any flat surface. Use proper equipment to
install this fixture, as a dropping fixture may cause severe injury! Ayra is not responsible for any
damage or injuries caused by improper installation.
Cleaning
Make sure to clean the exterior of the unit frequently, as the build-up of dust and dirt may have
negative effects on the cooling and optics of the fixture.
The exterior (plastic parts) of the unit can be cleaned with a damp cloth. The optics of the fixture can
be cleaned with a clean cloth or paper towel, with the addition of a non-aggressive glass cleaning
solution.
Clean the fan outlet and the cooling vents with a small brush, while using vacuum cleaner suction to
remove any loose dust and/or dirt.
Clean the exterior of this fixture once a month. When using this fixture intensively, the frequency of
maintenance needs to be increased.
Transport
When using this fixture in mobile setups, provide sufficient protection during transport. Use the original
packaging of this unit, or use a professional flightcase with proper foam inlay. This way the electronics,
optics and housing are protected against severe shocks, exterior damage and failing electronics.
Make sure the moving parts of the movinghead (pan and tilt motors) are secured during transport.
Shocks and fierce movement of the pan and tilt stepping motors may cause permanent damage.
After use, let the unit cool down for at least 10 minutes. When using DMX, use the ‘black out’ option on
your DMX controller. This way the unit is positioned in a static stand-by mode and the internal fan is
able to cool down the internal electronics, which decreases the chance of damage during transport.
Replacing the internal fuse
First check whether a failing power supply may be the cause of malfunction. When you suspect that
the internal fuse is broken, the fuse can be replaced by removing the fuse cover, located directly below
the power inlet.
WARNING: Before changing the fuse, always disconnect the fixture from your wall outlet or any other
power supply to prevent electric shocks.
Always replace a broken fuse with a fuse that has the same type and rating. After the fuse has been
replaced, always close the fuse-cover. Reconnect the fixture to your power supply and check whether
the problem is solved. When this does not solve your problem, contact your local dealer for help.
IMPORTANT: A spare fuse is located inside a special compartiment of the fuse holder.
Spare parts
This unit has no user serviceable parts inside. When any damage to internal components occurs,
contact your local dealer or a specialized technician in order to repair the fixture.
Focus
Below the beam output lens, there is a manually adjustable focus system. This way you can optimize

11
the output of the fixture, providing sharp beams and gobo projections on both short and long
distances.
Warning: To prevent damage to the stepping motors, only change the focus when the unit is turned
off, or when it is in a static position (by using DMX). Adjusting the focus while the head is moving, may
cause damage to the stepping motors.
Checkup
To prevent dangerous situations, make sure your fixture is in optimal condition before using it. Check
your fixture frequently by using the following checklist:
- All screws must be mounted tightly.
- Check all screws and metal parts for corrosion. No visible corrosion may be present.
- The exterior of your fixture must be in optimal condition. Check your fixture for dents, cracks or
missing parts.
- Your installation spot must be in optimal condition. Check your installation spot for corrosion, cracks,
dents and strength.
- Electrical components (connectors and cables) must be in optimal condition. Any form of damage
(cuts, exposed wire cores or any other visual deformities should not be present.
If any visual or mechanical damage is detected, contact your local dealer or a specialized technician.
Do not use a damage or failing fixture.
