MI-LED ILLUMINATOR

A Product of Dolan Jenner Industries

Introduction

The Fiber-Lite® MI-LED is a bright white, LED powered, fiber optic illuminator designed for general microscopy use.

When used with specialty fiber optic cables the MI-LED illuminator can also be used in a variety of laboratory

illumination applications.

Caution: Possible hazardous optical radiation emitted from this product. Do no stare at operating lamp. May be harmful
to the eyes. In accordance with the EN 62471 standard the MI-LED Illuminator is a product of Risk Class 2.

Warning ! : This label designates an area that may pose a health hazard. Caution should be used wherever this label is
present.

Warning Hot Surface: This label designates an area that may be hot to the touch and caution should be used.

Warning Risk of Electrical Shock: This label designates an area that poses an electrical hazard and caution should be

used.

Initial Setup

1) Remove the MI-LED Illuminator from the carton and retain any additional items and
accessories.
Inspect the unit for any physical damage that may have occurred during shipment. Please contact your supplier
immediately if any damage is observed.

2) If the illuminator was purchased as part of a Fiber Optic system, remove the fiber optic cable from the carton. If
the system includes an EEG2823M or BG2820M self-supporting gooseneck fiber optic cable then also remove
the LH759 lens(es) from the carton. The EEG2823M (dual) fiber optic system include two(2) LH759 lenses while
the BG2820M (single) system includes one(1) LH759 lens.

3) Loosen the fiber optic nosepiece thumbscrew.

4) Insert the fiber optic tip into the illuminator nosepiece. If the fiber optic is either an EEG2823M, or BG2820M self­supporting gooseneck style cable then the tip of the cable will have a small dimple in the tip. The dimple in the tip
will properly align the fiber optic cable in the nosepiece and prevent rotation of the cable. Align the dimple in the
tip with the nosepiece thumbscrew. Ring light fiber optic cables do not have a dimple and can be installed without
special alignment.

5) Tighten the thumbscrew by hand to make a secure connection to the fiber optic. Use of pliers or other tools is not
recommended. Use of tools may result in damage to the illuminator or the fiber optic cable.

6) Locate the Mi-LED in a workspace that allows for proper airflow. The Mi-LED is fan cooled and requires 2 inches
of space on each side for air flow.

7) Insert the AC power cord into the power entry at the rear of the illuminator. Use only
approved power cord supplied with the illuminator.
Insert the AC power cord into the proper AC mains outlet for the illuminator voltage ordered. If any doubt exists
consult the labels on the rear and underside of the illuminator before connecting the illuminator to AC power.

Fiber Optic Connection

The MI-LED(B1) illuminator uses a B-type fiber optic nosepiece with a 0.590 in. (15mm) ID. B-Type nosepieces will

accept self-supporting goosenecks (EEG2823M, BG2820M) and ring light (A3739M) fiber optics without the need for

an adapter. Fiber optics smaller than the 0.590 in. (15mm) ID will require an optional adapter.

Operation

All the MI-LED series illuminators are equipped with a front panel manual solid state intensity control.

Press the ON(1)/OFF(0) rocker switch on the front panel to ON(1). The illuminator will light and is ready for service. The

illuminator intensity is controlled by the rotary control located on the front panel of the illuminator. The 0 position (when

control is turned fully counter-clockwise) corresponds to the lowest illuminator intensity. The 100 position (when control is

turned fully clockwise) corresponds to the highest illuminator intensity.

NOTE: There is not a replaceable internal lamp. Long life LED's provide bright illumination for the lifetime of this

fiber optic illuminator.

Risk of electrical shock. Illuminator should be in upright position and remove power cord before Fuse replacement.

WARNING

Replace the fuse with the correctly rated fuse as listed on the label on the back of the illuminator. Use of an improper

fuse can create a hazardous condition.

Fuse Replacement

1) Press the ON(1)/OFF(0) switch to the OFF(0) position.

2) Remove the AC line cord from the power entry module at the rear of the illuminator.

3) The fuse drawer is part of the power entry module. The drawer is located directly beneath where the AC line cord
plugs in.

4) Remove the fuse drawer. Only one fuse is required. Remove the blown fuse from the drawer and discard.

5) Place the replacement fuse into the fuse holder by inserting either end of the fuse into the fuse holder.

6) Push the fuse drawer until it "clicks" into position.

7) Attach the AC line cord to power entry module at the rear of the illuminator.

8) The illuminator is now ready for service.
