Proper Use The colorCONTROL MFA-5 is a testing system that uses an opto-electronic sensor in combination with a fiber optic cable (POF 2.2 mm) to test intensity, color and function of illuminants such as LEDs and incandescent bulbs.
Functional Principle, Technical Data Functional Principle, Technical Data Short Description The colorCONTROL MFA-5 is a testing system that measures both color and function as well as intensity of light emitting diodes (LEDs) quickly and automatically. Technical Data MFA-5/ -M Model...

Check for completeness and shipping damage immediately after unpacking.
Installation of the colorCONTROL MFA-5 Mount the sensor in your test set-up using four M3 screws. The colorCONTROL MFA-5 can be mounted both on the top side as well as on the bottom side of your test set-up. Ensure careful handling during installation and operation.

Optical fibers smaller than ø 1 mm can also be fixed with a clamping collet E39-F9 in addition to the guide sleeves 1 mm. Fixing with a silicone adhesive is not necessary thereby. The optical fiber is fixed; however, it can be replaced if required. Fig. 7 Clamping collet E39-F9 colorCONTROL MFA-5 Page 15...
Installation 4.2.5 Shortening the Optical Fiber The optical fibers of the colorCONTROL MFA-5 are shipped with a length of approximately 600 mm as stan- dard. Shorten the optical fiber to the optimum length. NOTICE > This prevents damage to the optical fiber.
4.3.1 Individual colorCONTROL MFA-5 Sensor The colorCONTROL MFA-5 can be operated both via an RS232 as well as via a USB port. In USB operation, the power for a sensor is supplied via the USB interface. In RS232 operation, an external power supply of 10 - 30 VDC, approximately 80 mA (max. 320 mA) must be used.

Operation Operation Commissioning Make the following settings after the MICRO-EPSILON LED Check software has been installed and the color- CONTROL MFA-5 has been connected: 5.1.1 Configuration: Port (Interface) The USB port is configured as virtual COM port and is designated as Com5, Com6 etc.
Page 22
Operation The colorCONTROL MFA-5 test program is a graphical tool which can send commands to and receive results from the colorCONTROL MFA-5. The LEDs are tested individually. The results are saved in a file (e.g. TestReport.txt). The program specifies the optimum setting for the LED to be tested. For operation of the colorCONTROL MFA-5 program, see Chap.
Pin no. 6 side Pin no. 6 side Fig. 17 Color chip of the colorCONTROL MFA-5 with High and Low Sensitivity Mode In addition to both the High Sensitivity Mode and Low Sensitivity Mode, the light intensity can also be influ- enced via the measuring time of 1 ms to 10000 ms.
This can be done during the installation of the firmware using a non-volatile stored offset. 2. It is also possible to integrate the colorCONTROL MFA-5 in an existing test system via initialisation of the COM port and a command set, see Chap.

In the case of an application with several LEDs with the same light intensity, it is sufficient to determine the setting of the color chip range for one LED in this way. Afterwards, this setting can be transferred to the other checkpoints / color chips using the Measurements window, see Chap. 5.2.4. colorCONTROL MFA-5 Page 34...

This command is used for checking the connection between the test system / PC and the colorCONTROL MFA-5. If only one colorCONTROL MFA-5 sensor is connected to the sensor and the connection is present, the "OK" response is received. If several colorCONTROL MFA-5 sensors are connected, the number of the colorCONTROL MFA-5 sensors is also indicated, e.g.
This command tells the colorCONTROL MFA-5 to check and save the colors and intensity of all connected LEDs at the same time. The test time and the color chip sensitivity range (9x9; 3x3) can be set before the actual test using the com- mand setcaptimexyz b, see Chap.
For very bright LEDs, the Sensor Low setting is selected (only 3x3 segments of the color chip are used) and the test time is reduced accordingly (e.g. 10 or 2 ms). Board = colorCONTROL MFA-5 Channel = checkpoint colorCONTROL MFA-5...

Which Types of LEDs and Colors can be Tested? The colorCONTROL MFA-5 records the complete spectrum of visible light (390 - 780 mm) from light emit- ting diodes (LEDs). All sizes and forms and very bright or very dark LEDs can be tested. As well as standard LEDs, bi-color and tri-color LED displays and luminous bar displays can also be tested.
Yes, provided you treat each segment as an individual LED and mount an optical fiber over each segment. The displayed numerals from 0 to 9 can thus also be tested. At least 7 checkpoints are needed for this (1x colorCONTROL MFA-5 + 1x colorCONTROL MFA-5-M + as- sembly kit MFA-10).
Which Output Formats can be Provided by the colorCONTROL MFA-5? The colorCONTROL MFA-5 can provide the data both via a USB or RS232 interface. The results can be out- put both as RGB, HSI or CIE values as well as the color temperature in Kelvin.
A 3.19 How High is the Power Requirement? The colorCONTROL MFA-5 with 5 channels has a current consumption of approx. 80 mA, for 24 V (5 V with board version). The colorCONTROL MFA-5 can be operated both via an RS232 as well as via a USB port.
