1. Introduction
This manual is designed for technical personnel and is written to provide
an understanding of the equipment, as well as a plan for troubleshooting.
All OLEC lights respond to existing conditions. There are no fixed
cycles or timers. This allows the unit to respond correctly to conditions
that are not normal to operation, such as power failure or surges. Learning
what conditions cause the various responses will guide you to the
solutions.
This manual was written in several sections, each to provide information
in a different manner or specialized locations. Here is a quick guide to
the sections.
Features: A comparison between our lights and conventional light
sources, with an explanation of each feature, is provided to demonstrate
why we chose to design a light source so different from other sources.
Component Layout: Where to look for components referred to in the
manual.
Note: The AL9 and AL13 units are very similar. The AL15, ALI15,
AL19, AL20, AL23 (power supply only for the AL23) units are
very similar but some have fewer parts. The AL23 (lamphead
only for the AL23) AL25, AL25-2, AL35, AL50, AL53, AL54,
AL54-480, AL55, AL55-480, AL56, AL56-480, AL83, AL84,
AL84-480, AL85 and AL100 (power supply only for the AL100)
units are very similar but some have fewer parts. The AL100
lamphead shares some of the same internal components with the
other lampheads but the arrangement is quite different.
Troubleshooting: An outline of where to look for various symptoms.
This guide refers to the more detailed information in the general
information section that follows.
General: Contains specific information about the components in the
light and the path of the signals and power. It can be used for information,
or used with the troubleshooting guide.
Lamp Head Signals: Provides information about all the conductors to
the lamp head, their functions, and the voltages present.
Light Function States: A chart of the different functions the board
directs and the conditions that cause these functions. There is also a
description of the states.
Printed Circuit Board Pins: Provides the pin-outs from the printed
circuit board and an explanation of each.
Schematics: Full-unit schematics are provided. They are for the AL 9,
AL 13, AL 15, ALI 15, AL19, AL20, AL23, AL35, AL50, AL53, AL54,
AL54-480, AL55, AL55-480, AL56, AL56-480, AL83, AL84, AL84-
480, AL85, AL100.

2. Safety
Questions have been raised regarding the possible danger of exposure to
UV for equipment operators using high power lights. We address this
issue in terms of overall safety of such lights. OLEC lights are UL
approved and meet the strictest US electrical and safety standards,
including all OSHA requirements. Users and dealers should insist on
U.S. safety approval. It is required by law.
The Nature of UV
UV rays have been divided into three categories: UV“A” from 400-
315nm, UV“B” from 315-280nm, UV“C” for the shorter waves. UV
extends to about 10nm but air will filter out most rays shorter than 200
nm. To put this into perspective, the “near UV” or UV“A” is immediately
adjoining the visible spectrum extending from the color violet. Violet
extends to about 380 nm; red is at the opposite end of the visible spectrum
at 700 nm (see Illustration: Electromagnetic Spectrum). Most light
sources, including light bulbs, emit a certain amount of UV.
UV, Source of Health
Before one becomes unduly concerned with the harm UV can cause, it is
important to understand the many beneficial effects connected with
working outside and in bright areas with a certain amount of the “right”
UV. The germicidal effect, for instance, can rid the air of bacteria and is
used for that purpose extensively in hospitals. Exposure of the skin to
UV produces Vitamin D, necessary for the formation of bones and teeth.
Exposure to UV“A” is essential to life itself. Most life, human, animal
and plant, depends on it for growth and health.
Bad UV
One must avoid UV“B” and UV“C” even in small doses. UV“A” is
harmful only through overexposure. Never confuse the effects of UV
with the great harm that can be caused by microwave and X-ray radiation,
much of such damage being irreversible.
UV in Nature
Sunlight contains an abundance of UV, UV“A”, “B” and “C”, and the
negative effects of overexposure to sunshine have become well known.
These are primarily sunburn, sore eyes, headaches. Cataracts and skin
cancer are caused by prolonged exposure. Very damaging is the
erythematic energy, UV“B”, that penetrates the natural filter of ozone in
the upper layers of the atmosphere.

2-2 94MS20 Rev. B4
Ozone, UV“B” and UV“C”
No UV“C” is generated by OLEC lamps. OLEC lights and lamps use
“Ozone Free Quartz” for safety reasons to filter out most of the potentially
harmfulrays in theUV“B” region. Somemanufacturers do notuse “ozone
free quartz.” Such lamps require greatly enhanced protection through
safety glass, curtains, light tight housings, and special exhaust systems
to rid the air of ozone. If you smell ozone in your workplace, speak to
your supervisor or employer. DO NOT work under those conditions!
Safety Glass
Carefully selected safety glass is used on all OLITE UV lights under
the reflector. It filters out nearly all the remaining UV“B” so effectively
that any transmission is almost impossible to measure. This safety glass
is equipped with an important electrical interlock to prevent use of the
light if the glass is missing or installed improperly. Never use a light that
does not have a protective safety glass.
Light Leaks
Light heads that leak light around the safety glass during idling periods
should be avoided. Light above the safety glass always contains a certain
amount of UV“B”, particularly when NON-ozone free lamps” are used.
Poorly constructed light housings, with even small parts of the lighted
area of the lamp or the reflector visible during standby, can be dangerous.
Such lights are best used within an enclosure that is shut completely at
all times, especially during extended idling time. According to NIOSH,
UV“B” is quite different in its effect from UV“A.” It is cumulative and
between 600 to 1000 times as destructive.
Being exposed to constant UV leakage during idling time can quickly
exceed the daily maximum safe limit and eventually cause serious
personal damage. Never use or have anyone else use a light with leaks
past the safety glass (where you can see lamp or reflector from any
direction)!
Overexposure to UV
What constitutes overexposure to UV“A” should be considered in terms
of safe limits and the trade-off between documented health-promoting
effects of UV and danger of overexposure. For the UV“A” region, the
UV effecting exposure on film and plates, it is recommended that the
total radiant incidence on unprotected skin and eyes should not exceed
1.0 mW per cm2for periods longer than 1000 seconds (16 minutes). This
is the Standard, documented and recommended by the National Institute
for Occupational Safety and Health, NIOSH, a basis for OSHA.
For UV intensity under 1.0 mW per cm2there is no time limit. With
higher intensity the time should be reduced so that the total dose does
not exceed 1000 mW-sec/cm2(1 mW/sec = 1 mJoule).
