2.1.2. Main Sources of Danger

DANGER!

Electric shock due to electric charge inside the housing.

Immediately after disconnection, the contacts of the mains plug may still carry voltage for a short period.

 Do NOT touch the contacts of the mains plug directly after switch-off.

DANGER!

Functional impairment of electrical devices due to electromagnetic radiation.

Electromagnetic radiation emitted by the M=Light LED may impair proper function of electromedical devices.

 Keep a distance off the operating M=Light LED of at least 1 m if you

have a cardiac pacemaker, defibrillators or other electronic implants.

DANGER!

Striking of persons due to falling M=Light LED

M=Light LED falling from the crash lighting frame may strike persons dead.

 The M=Light LED must be securely screw-fixed with the crash lighting

frame using an attachment screw of proper dimension.

 For screw-fixing the M=Light LED to the crash lighting frame, exclusively

use the attachment holes in the support bracket (Figure 10, Item 3 and 4, page 19).

DANGER!

Electric shock and burning hazards at melting power cable.

Using the wrong power cable may lead to overheated power cable and thus to the risk of burning hazards and electric shock due to melting power cable.

 Only use the power cable delivered with the M=Light LED by

MESSRING.

3.1. Setup and Functioning

LED flood light for steady and pulsed operation. Pulsed operation is synchronized with the high-speed camera. In pulsed operation, 80% more

lighting power can be output compared to steady operation. This is possible because the lighting is only switched on when the camera requires light. The M=Light-LED can optionally be operated manually or via the CAN-bus with the help of the software. In pulsed operation it is possible to eliminate backlight effects due to control of separate M=Light-LED groups. For elimination of backlight effects, only one camera synchronized with one M=Light-LED group is switched on (Figure 1).

5.3.5.1. Auto-Follow Operating Mode

In the Auto-Follow operating mode, not only the switch-on pulse is adapted according to the Sync signal from the camera system but also the values for Pulse period, Pulse width and Pulse delay.

Requirements for the Sync signal from the camera control:

I electrical signal at which the pulse duration and the frequency of the signal corresponds to the

exposure time.

I With the Auto-Follow selected for the M=Light LED, the duration of the switch-on pulses and the

intensity set must comply with the diagram that is shown in the software (Figure 16).

Description

Black characteristic curve

Maximum permissible limit values with a defined output of up to 150%.

Red characteristic curve

Upper limit values with a defined output of more than 150%. In this scenario, the lower limit values are identical to the limit values for <150%.

I Rough reference values for the permitted switch-on duration at common flash times:

 With an intensity of <150%, set the switch-on duration at <50% of the period of used

frame rate (Pulse period / Pulse width ≤ 2/1).

 With an intensity of >150%, set the switch-on duration at <20% of the period of used

frame rate (Pulse period / Pulse width ≤ 5/1).

5.3.5.2. Error message in the Auto-Follow operating mode

Error in flash signal

Error cause:

I The Sync signal emitted by the camera system does NOT comply with the permitted switch-on

duration of the M=Light LED at the pre-selected intensity.

Consequence of the error:

I Triggered switch-on processes are not performed, which may result in bright > dark frame

sequences in the shots.

Preventing errors:

 Check if the Sync signal emitted by the camera system corresponds to the permitted switch-on

duration of the M=Light LED at the pre-selected intensity.

 Adjust the intensity of the M=Light LED at the Power slide control in the Flash Light window.  Adjust the frame rate of the camera system.  Adjust the exposure duration of the camera system.

 You have adjusted the input signal to the physical limits of the M=Light LED and are now able

to produce high-quality shots with good exposure.

Switching on the Auto-Follow operating mode:

 Highlight the required M=Light LED.  Select the trigger input.  Slide the Pulse period slide control to 0.  Adjust the required intensity for the switch-on duration between 1 and 255% by means of the

NOTICE!

Failure of the M=Light LED due to incomplete firmware or FPGA update

If the update of an M=Light LED is aborted, this may result in failure of the M=Light LED.

 The firmware or FPGA update must always be completed.  Any M=Light LEDs failed due to an incomplete update must be sent to

MESSRING for repair.

Performing a Firmware Update

 Highlight an M=Light LED using the left mouse button.

 Press in section Firmware Update.  The browser window for selection of the update file is opened.  Only use update files that have been approved by MESSRING for your M=Light LED.  Press Update.  Wait for the update to be completed, DO NOT abort the process.

5.3.7.1. Grouping the M=Light LEDs in M=Light Explorer

After installation of M=Light Control, NO groups are defined yet. In M=Light Explorer all M=Light LEDs connected to the system are listed one after the other.

If you perform regular parameterization of a certain group of M=Light LEDs, it is meaningful to group this array in order to be able to perform parameterization simultaneously for the entire group.

It is also possible, to assign one M=Light LED to several different groups at a time. In the c:\Program Files (x86)\Messring\MLight\ directory, there is a file example_Groups.ini with the

following contents:

 Open the example_Groups.ini file from the directory c:\Program Files (x86)\Messring\MLight and

adjust it in accordance with the grouping settings of the M=Light LEDs in your installation.

 In the case that you have NOT installed any switches, enter 0 for the SwitchCount.  If switches are installed, adjust the address of the switches as necessary.  Adjust the M=Light LEDs, groups, and addresses in accordance with your installation.  Save the adjusted file in the same directory using the file name Groups.ini.  Restart M=Light Control.  Re-connect the M=Light LED using Connect.

 The groups are now displayed in the M=Light Explorer in the same way as is defined in the
