Page 3: Introduction
Photobiological safety of lamps and lamp systems - IEC 62471:2009 Intended use The LG3 is a high-intensity illuminator based on LED technology for transparent charts. It is capable of flicker generation with variable frequency and variable duty cycle. The external controller unit and the LG3 Software can control the device. -
Page 4: Eye Safety
1.3.2 Eye safety The LEDs used in the LG3 can be classified as belonging to the Exempt Group or Risk Group 1, according to IEC 62471:2009. 2 GETTING STARTED Scope of Delivery • LG3 control unit • LG3 illumination unit •... -
Page 5: Operating Instructions Hardware
Connect the illumination unit (1) to the control unit (2): • Plug the cable (H) into the socket (I) • All “open” marks must face to the front side of the device • Turn the lock ring clockwise for a secure connection Image Engineering Seite 5 von 14... -
Page 6: Starting The System
The power switch (F) is located on the upper side of the control unit. 3.3.1 Calibration The LG3 has a stabilized intensity output, and the system needs to be calibrated to use the output feedback in cd/m² or lux. The LG3 provides two calibration modes. -
Page 7: Continuous Illumination
Continuous illumination Use continuous illumination when illuminating test charts. The continuous illumination is preset as a default on the LG3 start-up. Read chapter 3.5 on how to enter and exit the flicker mode. 3.4.1 Power modes Three power modes are available •... - Page 8 Puls Width Modulation with 32 kHz (simplified representation) 0,01 0,02 0,03 0,04 0,05 0,06 0,07 0,08 0,09 Time [ms] Relative Intensity Period Time_on Time_off LED intensity over time at 32 kHz pulse width modulation with 50% duty cycle Image Engineering Seite 8 von 14...

Page 9: Setting The Illumination Level
0– 0) Third line: set the flicker duty cycle. (Chapter 3.5) • The stabilization of the set intensity may take up to 10 seconds • Press button (D) to turn the illumination on and off. Image Engineering Seite 9 von 14... -
Page 10: Intensity Stabilization
Light emitted by external light sources or reflected by objects in front of the LG3 can enter the illumination unit and affect stabilization. Place the illumination unit in a dark room and avoid reflective and moving objects in this room. -
Page 11: Flicker
The LG3 simulates different light sources with its capability to vary the duty cycle and frequency of the illumination. The adjustable duty cycle settings of the 32 kHz frequency can change the illumination, and the flicker frequency is modulated on the 32 kHz frequency. - Page 12 0– 0) Third line: set the flicker duty cycle. • Press button (D) to turn the illumination on and off. • For a quick switch between continuous and flicker mode, press the rotary knob (A) Image Engineering Seite 12 von 14...

Lift the fuse cover located over the power switch using a small flathead screwdriver • Lift the red fuse holder using a small flathead screwdriver • Replace the defected fuse • Place the fuse holder back into the fuse holder socket • Close the fuse cover Image Engineering Seite 13 von 14... -
Page 14: Storage And Transport
Store and transport the LG3 only in the delivered hard case. Disposal instructions The LG3 must be disposed of properly after the service life is over. Electrical and electromechanical components are included in LG3. Observe your national regulations and ensure that third parties cannot use LG3 after disposing of it.
