GETTING STARTED
STOPPING THE BLUR
The Unilux Beacon uses stroboscopic lighting to “freeze action”.
When objects move at high speed, the human eye cannot focus on a single image. As a result, the eye can only see "blur". But strobe lighting stops the blur. By flashing with high intensity for extremely short durations, a strobe light will "freeze" objects traveling at speeds that cause blur. [ See Illustrations Below ]
WITHOUT STROBE
[ BLUR ACTION ]
WITH STROBE
[ FREEZE ACTION ]
During these short flashes, an object moving at 600 meters per minute moves only 0.2mm - so it appears to be stationary since the eye captures and retains only brief visual images. This result makes detailed inspection possible. No other type of light provides this kind of clarity and definition of surfaces in motion.
SHORT FLASH, HIGH DEFINITION
The length (duration) of time that the light is actually on for (flash) and its brightness in respect to ambient light, affect clarity. The shorter the flash duration, the sharper the image. The more the light from the strobe dominates the ambient light the better. Unilux recommends strobe lighting levels four times brighter (4x) than the ambient lighting.
WHITE LIGHT
Unilux inspection lights emit an excellent white light approaching sunlight that reveals true colors. The light's scientific color temperature is 6500 Kelvin.
Getting Started 4

HOW TO SET THE FLASH RATE
Flash rate should be adjusted within these limits for non-synchronous inspection. Non-synchronous inspection is defined as looking for flaws or random events on non printed webs moving at production speeds.
(Note: In pattern inspection, flash rate must be set to synchronize).
FOR SURFACE QUALITY ON STEEL / PAPER / FILM
Adjust flash rate to exceed 50 Flashes per Second (F/S) (3000 per minute). Rates below 50 F/S can be dangerous and disruptive to personnel affected in the immediate area (See Warning on first page). Therefore, 50 F/S should be your minimum flash rate.
Flash rates should not allow more than 15cm to 30cm of material to pass between flashes. Therefore, to calculate the maximum rate, divide the line speed in centimeters per second by 30, and this will be the maximum flash frequency in Flashes per Second.
Experience gained from many industries using non-synchronous inspection lighting shows that flash rates between 60-80 F/S (3600 - 4800
Flashes per Minute, F/M) work best depending on speed of the material.
For synchronous inspection of printed webs or rotating parts, set the Beacon flash rate to the highest setting. While viewing the action lit by Beacon, gradually lower the flash rate. When the first single image appears, the light is synchronized to the exact repeat speed of the web or rotating part. The display will indicate the speed in repetitions per minute or second.
For paper formation / activity studies, Flash Rates between
25-35 F/S work best depending on speed and type of paper made.
5 Getting Started

I . I N T R O D U C T I O N & A P P L I C AT I O N
The Unilux Beacon is a compact industrial surface inspection spotlight, specifically developed for wide web paper formation applications.
The Beacon provides narrow beam spot illumination of a flat surface covering
50cm to 100cm. This illuminated area results when using the Beacon at its intended .5cm to 5m distance.
Larger areas can be illuminated by using the Beacon at greater distances, however, this will result in a corresponding reduction of light at the surface being inspected. [see PHOTOMETRY , page 19]
Other Unilux products are better for illuminating areas larger than the capacity of the Beacon. Contact your Unilux representative for complete product information.
External and Internal Trigger Mode
The flash rate of the Beacon can be controlled by an external trigger signal, or the flash rate Up & Down control keys.
In External mode , the Beacon will flash synchronously with each external trigger signal event.
The Beacon provides two external trigger input channels which are factory set for accepting the following signal types.
V - C Option: Video & Contact Closure
• Video: 1v p-p unterminated, triggers on 50Hz or 60Hz vertical sync.
• Contact: Contact closure or open collector, > 8VDC @ 10mA rating
V - P Option: Video & Pulse
• Video: 1v p-p unterminated, triggers on 50Hz or 60Hz vertical sync.
• Pulse: +2.5V pk minimum, > 100µsec pulse width.
Note
When the external trigger connector is installed, the internal rate control is disabled.
I: Introduction & Application 6

In Internal mode , the flash rate is set by using the Up & Down rate control keys.
The Up & Down control keys provide a means for setting or scanning the flash rate over the range of 30 Flashes per Minutes (F/M) to 18,000
F/M maximum.
Pressing and releasing the Up & Down keys changes the flash rate in single steps. By pressing and holding the Up & Down keys for longer than 1 second, the flash rate is scanned at an approximate speed equal to 10F/S per second.
Three Intensity Levels
The Beacon provides three intensity levels for tailoring the flashlamp brightness to the actual inspection application.
The flashlamp intensity is set by using the intensity control key to select 100%, 66%, and 33% levels, depending on the operating flash rate.
The selected intensity level also selects the flash rate range and automatically limits the maximum flash rate.
Three Flash Rate Ranges
The Beacon unit provides three flash rate ranges, all contained in one model type.
Maximum flash rates of 6000 F/M, 12,000 F/M, and 18,000 F/M are provided and are automatically set by the selected intensity level as follows:
Intensity Level
100%
66%

FULLY CHARGED ..................
HOT/COLD PACK DELAY ......
REPLACE PACK ......................
PROBLEM POWER LINE ......
HOT/COLD PACK DELAY
When the charger detects a DC Power Pack that is hot or cold, it automatically starts a Hot/Cold Pack Delay, suspending charging until the pack temperature has stabilized. After the DC Power Pack cooled, the charger automatically switches to the Pack Charging mode. This feature ensures maximum battery life. The red light flashes long, then short while in Hot/Cold Delay mode.
REPLACE PACK
The charger is designed to detect certain problems that can arise with DC
Power Packs which would be indicated by the red light flashing at a fast rate.
If this occurs, reinsert DC Power Pack. If problem persists, try a different pack to determine if charger is OK. If the new pack charges correctly, then the original pack is defective and should be returned to Unilux for recycling. If the new DC Power Pack elicits the same trouble indication as the original, have charger tested by an authorized Unilux service center.
PROBLEM POWER LINE
If the input voltage is out of tolerance, the charger may temporarily suspend operation and begin flashing the red light (two fast blinks followed by a pause).
This indicates the power source is out of limits. If the voltage returns to an acceptable level, the charger will automatically switch to a normal charging mode and flash accordingly.
LEAVING THE DC POWER PACK IN THE CHARGER
The charger and DC Power Pack can be left connected with the red light glowing indefinitely. The charger will keep the DC Power Pack fresh and fully charged.
23 VIII: Charging the DC Power Pack

IMPORTANT CHARGING NOTES
1. Longest life and best performance can be obtained if the DC Power Pack is charged when the air temperature is between 65°F and 75°F (18°C - 24°C).
DO NOT charge the DC Power Pack in an air temperature below +40°F
(+4.5°C), or above +105°F (+40.5°C). This is important and will prevent serious damage to the DC Power Pack.
2. The charger and DC Power Pack may become warm to touch while charging.
This is a normal condition, and does not indicate a problem.
3. If the DC Power Pack does not charge properly, (1) Check power at receptacle by plugging in another piece of equipment, (2) Move charger and pack to a location where the surrounding air temperature is approximately 65°F - 75°F
(18°C - 24°C), (3) If charging problems persist, take or send the equipment,
DC Power Pack and charger to an authorized Unilux service center.
4. The DC Power Pack should be recharged when it fails to produce sufficient power enough to keep the equipment functioning properly.
DO NOT CONTINUE to use under these conditions. Follow the charging procedure. You may also charge a partially used pack whenever you desire with no adverse affect on the DC Power Pack.
5. Under certain conditions, with the charger plugged in to the power supply, the exposed charging contacts inside the charger can be shorted by foreign material. Foreign materials of a conductive nature such as, steel wool, aluminum foil, or any buildup of metallic particles should be kept away from charger cavities. Always unplug the charger from the power supply when there is no DC
Power Pack in the cavity. Unplug the charger before attempting to clean.
6. Do not immerse charger in water or any other liquid.
7. For optimum performance, leave the DC Power Pack in the charger for six hours or more once every 10 to 20 recharges. This balances the cells, keeps the pack at peak performance and extends the usable life of the pack.
WARNING: Don't allow any liquid to get inside charger. Electric shock may result. To facilitate the cooling of the DC Power Pack after use, avoid placing the charger or pack in a warm environment.
CAUTION: Never attempt to open the DC Power pack for any reason. If the plastic housing of the pack breaks or cracks, return the DC Power Pack to
Unilux.
