1. General information

Please read this manual carefully, it describes the hazard the user might be exposed to while

using the product. It also explains in details how to use the product in the safest and more

efficient way possible.

The safety of any system incorporating the product is the responsibility of the assembler of the

system.

Any actions taken by the user that is not clearly described in this user manual might present a

risk and is the sole responsibility of said user.

This product is to be used in laboratory or industrial tasks, and only by personnel who have

followed a training in laser hazard.

1.1. Definitions

Caution : A caution is advised when dealing with hazardous situations, tasks or objects, to prevent

harm or death and avoid material damage or failure.

Warning : A warning is given for potentially dangerous situation for people which cause them

harm or lead to death

Note : A note is a complementary piece of advice that must be acknowledged by the user.

1.2. Laser hazard and general warning

WARNING

The compatible laser diodes used with the CCMI can deliver up to several Watts of coherent

LASER radiation. This product contains a CLASS 4 laser. Always wear protective goggles and

observe the safety instructions with respect to laser radiation directive (2006/25/CE).

Page 4/26 –v1.0

WARNING

Closing the software or removing the USB cable between the product and the PC do not stop

the laser emission.

To stop the laser emission, open the interlock or disconnect the power supply of the CCMI.

WARNING

Operating the CCMI with respect to laser radiation directive (2006/25/CE) is the responsibility of

the owner of the system and the product should not be put in operation before the machine or

system in which it will be integrated has been declared to be compliant with the relevant

requirements (NF EN 60825-1).

WARNING

Do not try to open or remove the cover of the CCMI module.

WARNING

Avoid all chocs and strains when handling the CCMI.

WARNING

Handle the fiber-optics cable with care as it is fragile. Do not bend or pinch it.

WARNING

Any software settings or hardware tinkering that is not described in this user manual or in the

usage recommendation may put the user or its environment at risk.

WARNING

The maintenance and servicing of the CCMI should not be executed by the end user : only

AERODIODE is able to maintain the CCMI.

Note

Only use the supplied USB cable.

Page 5/26 –v1.0

2. Safety Instructions

2.1. Wiring

Caution

-Please use cable of length inferior to 3m to power the CCMI in order to avoid EMC

compatibility (according to IEC61326-1)

-Please first connect the input pins to the board and then plug the 24V DC Power Supply

-Make sure that the pins are correctly screwed in

-Use caution when connecting the Power Supply

-Protect the power cord from being walked on or pinched particularly at plugs,

convenience receptacles, and the point where they exit from the CCMI module

2.2. Operating Environment

Caution

-Do not install near any heat sources such as radiators, heat registers, stoves, or other

equipment (including amplifiers) that produce heat.

-To reduce the risk of fire or electric shock, do not expose the CCMI to rain or moisture.

WARNING

Not following the safety recommendations and the caution mentioned above can lead to eye

damage.

2.3. Contact

If you have any question about the CCMI module, please contact AERODIODE.

Page 6/26 –v1.0

3. Fiber optic cleaning

The optical path after the connector must be completely under control before laser activation.

Please remove the power supply and the interlock of the product before each disconnection.

Always place the protective cap when the fiber is not connected to any accessory.

Before connecting the fiber, the end face must be cleaned.

If the end face is not clean, there is a risk of deterioration, permanent damage of the product

with loss of power and burn connector.

During the connector cleaning operation, make sure that laser emission is not possible (remove

the power supply and the interlock).

To clean the connector output, use a clean optical paper and acetone solution. Fold the optical

paper to make a rectangle and put acetone on it. Then place the end-face of the connector in

contact with the optical paper with a perpendicular position to the paper (you can rotate the

connector on the paper but don’t scrub the connector on the paper).

Blue LED indicates that the device is powered

3. Alarm indicator

Red LED indicates that an extreme condition is reached and has triggered the laser extinction

(Interlock open, CPU dysfunction or overheating)

Page 9/26 –v1.0

4. USB input

3.5 mm input jack used to connect the CCMI driver to the PC. Use the specific USB cable supplied

with your device

5. Daisy output

3.5mm output jack used to chain multiple CCMI drivers or any other device from the AERODIODE

line (CCMI, Central, CCS)

6. Photodiode 1 input [left: signal / right : GND]

Input connector for a first photodiode entrance signal. This signal is used for the Automated

Power Control mode (APC)

7. Photodiode 2 input [left: signal / right : GND]

Input connector for a second photodiode entrance signal (provision)

8. Interlock [left: signal / right : GND]

Connector interlock that must be shunted or connected to any interlock security system of the

machine/installation in order to allow laser activation and thermal regulation. The signal is a 3.3V

DC pull-up signal that must be grounded in order to allow emission.

9. Alarm output [left: signal / right : GND]

Output connector for alarm status monitoring (power, current, temperature) (low level indicates

alarm)

10. Monitoring electronic component temperature

Allows temperature monitoring when using the device on external monitoring mode (25°C

corresponds to 1.125 V) [left: signal / right : GND]

11. Monitoring current

Allows current monitoring when using the device without the software (185 mV/A)

[left : signal / right : GND]

12. Analog 0-2.5 V signal input for Ext Mode

Set here the relative laser diode current using a 0-2.5V signal input when CCMI has been

previously set in “Ext-Mode” in the “Current Source” panel of the software (the operating mode

should be kept to CW).

This signal could be used to make a current modulation (continuous, modulated or pulsed).

0 V = Minimum current

2.5 V = Maximum current
