1 Before you start

The Corona II illumination unit and the LED-Control Unit XLC4 have been thoroughly tested

and been shipped in perfect operating condition.

◼Carefully check the shipping box for damage that may have occurred during shipping.

Damages must be immediately reported to the shipping company and to Chromasens.

◼Make sure you have received all parts listed in the packing list.

◼Keep the original packaging for a possible return of the equipment! To prevent damage, the

Corona II illumination unit and the LED-Control Unit XLC4 unit have to be returned

correctly packed and in the original packaging material.

◼Read this document carefully and take account to the instructions and notes listed in this

document.

2 Highlights

The Corona II illumination unit is a LED line scan illumination device for industrial applications.

It provides bright, homogeneous and stable lighting, which is the only way to get high quality

images. The Corona II illumination unit can be controlled by the Chromasens XLC4 controller

as well as with third party current sources or flash controllers.

◼Highly-focused LED light

The Corona II illumination focuses the emitted LED light by means of a special and a

patented reflector technology. This reflector allows for perfect light shaping and is the

technological base for the outstanding homogeneity of the focused light. Due to the

usage of a mirror, the light focusing of the Corona does not - contrary to lenses –lead to

chromatic aberrations. Corona II provides a perfect and focused spectral homogeneity

without aberrations.

◼High illuminance

With a focus length of 60 mm and adequate heat dissipation, illuminance values up to

3.500.000 lx can be achieved.

◼High homogeneity

Due to the patented Chromasens technology, different number segments (170 mm each)

LED modules can be lined up without any loss in homogeneity.

◼Highly efficient passive cooling

The Corona II illumination comes with a very effective passive cooling system. The

cooling capacity of the lighting modules can be adapted to the installation conditions and

the requirements in light output by selecting a suitable heat sink. A liquid cooling system

is also available as fan cooling option.

◼Flexible configuration

The Corona II illumination module is available with overall lengths from 180 mm to 1360

mm in steps by 170 mm. All relevant colors are available: Red, green, blue and white as

well as different focus lengths: 60 mm, 95 mm, 190 mm and parallel.

◼Compact design and sturdy housing

Minimum size for installation is required, because the Corona II is controlled by an

external control unit. Due to its sturdy and dust-proof design, the Corona II can be used in

rough industrial environments, where lots of dust and abrasive materials are present.

◼External controllers

The Corona II units are designed for use with the Chromasens XLC4 LED Control Unit

but can also easily be adapted to a variety of other commercially available LED control

units by means of wire end ferrules.

Operation with the XLC4 controller allows the use of enhanced features of the Corona II

modules such as automatic current limitation, temperature sensing and LED functional

test.

The controller can run several Corona II modules.

◼Easy installation

The Corona II housing has pre-drilled mounting holes which allow for quick mounting.

3 Safety information

3.1 Presentation of safety information

Safety relevant information is presented as follows in this manual:

DANGER

Indicates an imminently hazardous situation which, if not avoided, will result in

death or serious injury.

WARNING

Indicates a potentially hazardous situation or task, which, if not avoided, could

result in minor or moderate injury.

Indicates a potentially hazardous situation or task, which, if not avoided, could result

in damage to the product or the surrounding environment.

3.2 Basic safety rules

Ensure the following:

◼The illumination unit shall always be in perfectly safe condition. If there is a malfunction of

the unit or if any parts of the unit are defective, operation must be stopped immediately and

the person in charge must be notified.

◼National and local standards, directives and regulations on health, safety and accident

prevention shall be followed.

◼Make sure you have read and understood this manual.

◼Only authorized specialist personnel may install, maintain or repair the illumination.

◼The personnel must be instructed at regular intervals about potential hazards.

3.3 Specific hazards

DANGER

To prevent or reduce the risk of electrical shock or fire, do not expose this unit

to rain or moisture.

WARNING

This unit may cause severe eye damage. Avoid looking directly into the light

source at all times.

Electrostatic discharge / electro-statically sensitive parts

Some components of the illumination are sensitive to electrostatic discharge. Always

observe the applicable ESD standards. Avoid the proximity of electromagnetic fields

or electro-static charge-up.

Make sure that the device, the tools and the persons handling the device have the

same electrical potential.

3.4 Alert labels on the equipment

Risks from hot surfaces

The housing of the illumination unit heats up during operation.

Do not touch hot surfaces without suitable protective gloves. Always allow hot

surfaces to cool down before carrying out any work on the unit.

Risks from optical radiation

Contact with optical radiation may result in injury.

Direct and long-term exposure of eyes and skin to light radiation must be avoided

because it could be hazardous to health.

Do not stare into the beam.
