The NL-200 current controller provides repeatable intensity control of LED lighting for machine vision
applications. It includes the intensity control, timing and triggering functions required for machine vi-
sion systems.
LED lighting needs a constant current supply as small variations in voltage can cause large variations
in light output. The NL-200 can set currents in steps of 0.1% (with a lower limit of 2.5mA steps to give
very fine control of intensity.
Before you start consult your NERLITE specification or product labeling for it's Current Rating. All
specifications can be found on the Omron Microscan website.
NOTE: This current rating is critical to the safe operation of the NERLITE, care must be taken
to determine the correct rating for the light to be connected to the NL-2XX controller.
NOTE: Lighting must not be connected to anything else and must not have a common con-
nection to other lights
NOTE: The NL series has SafePowerTM low heat technology so that in most cases
heatsinking is not required. SafePower also automatically "steps-up" the output volt
age, so that from a 24V supply a higher voltage (eg 36V) can be output.
1.) Read the sections on Safety (Section 3) and Specifications (Appendix A) and check the
NL-2XX fulfils your requirements.
2.) Mount the NL-2XX as described in Section 4.
3.) Connect the NL-2XX up to a supply as described in Connections (Section 5). When the front
panel is present, the NL-2XX should show two alternating lines on the display to indicate that
it is operating properly.
4.) Read Lighting Setup (Section 7) and then enter the current rating for the lights you need to
connect. Then connect the lights. NOTE: The current release of the NL-2XX does not sup
port Voltage Rating, use only Current Rating to operate your light(s).
5.) Set up the NL-2XX for the desired operation as described in the Configuration sections
(Section 8, 10 or 11).
