Precautions
UV Light Hazard! The MLR illuminator contains a high-power UVA LED. Do not look directly into the beam of light or expose skin. Do not attempt to disassemble or service an MLR device, except under the advisement of a Zaber representative.
Installation
Connect the MLR illuminator to the epi-illumination port of any Zaber MVR microscope. Connect the 3 LED channels to the X-LCA4 controller using the 5-pin locking M8 connectors.
Operation
The MLR LED peripherals are designed to be plug & play with Zaber's X-LCA4 controller. The controller will automatically detect the connected LEDs and apply appropriate driving currents when LEDs are activated. See the X-LCA4 Manual for more information on how to activate LED peripherals.
By default, the LED channels will be set to 0 brightness upon device initialization. To increase brightness, send commands to the X-LCA4 controller, or turn the manual control knobs.
