MVS-5770 MACHINE VISION STROBE OPERATION MANUAL

WARNUNG!

Das MVS-5770 erzeugt lebensgefährliche Spannungen. Es muss deshalb darauf geachtet werden,

dass der ankommende Strom ausgeschaltet ist und die Ladekondensatoren entladen sind, bevo

Kontrollen oder Regelungen am Gerät unternommen werden!

ATTENTION!

Le MVS-5770 fournit des tensions dangereuses. Veuillez vérifier que la prise de courant es

déconnectée et les condensateurs d'accumulation sont déchargés avant d'entreprendre des

inspections ou des réglages sur l'appareil.

WARNING!

The MVS-5770 produces lethal voltages. Ensure that input power is disconnected and

storage capacitors have been discharged before beginning any inspection or internal

adjustment.

WARNING!

The output voltage of the MVS-5770 MUST be limited to match the

specifications of those components to which it is connected. Exposing any

system component to voltage (or any other operating condition) that

exceeds its rating can result in damage to the unit and personal injury.

WARNUNG!

Die Ausgangsspannung des MVS-5770 muss der Leistung aller damit verbundenen Komponenten

angepasst werden. Systemelemente Spannungen (oder anderen Betriebsbedingungen) auszusetzen,

die die Leistungswerte jener Komponenten übertreffen, ist gefährlich und kann zu Schäden und

Verletzungen führen.

ATTENTION!

Il faut que la tension fournie par le MVS-5770 soit limitée aux caractéristiques des composants auxquels

il sera mis en contact. En exposant un composant quelconque à une tension (ou à d'autres conditions

de fonctionnement), qui en dépasse la limite on pourrait endommager l'appareil ou provoquer des

blessures.

WARNING!

Do not exceed the specified rates of voltage and flashrate. Do not operate at more than

50 watts of average output power.

WARNUNG!

Bitte, die vorgegebenen Grenzwerte bei der Spannung und Blitzfrequenz nicht übertertreffen.

Leistungen höher als 50 Watt sind nicht zulässig.

ATTENTION!

Eviter de dépasser les valeurs limits inscites pour la tension et la fréquence d’éclat. Eviter aussi des

puissances au dessus de 50 Watt

MVS-5770 MACHINE VISION STROBE OPERATION MANUAL

WARNING!

Strobe lights have been known to trigger seizures

in people with photosensitive epilepsy.

WARNING!

Avoid looking directly at the high intensity light

flash as this can result in damage to the eyes.

1.0 INTRODUCTION

1.1. DESCRIPTION

The MVS-5770 series illuminators are high intensity, low flash rate, Xenon strobes

for direct illumination. The system consist of a separate power supply and

flashhead chassis. A standard two and one half meter (2½m) interconnecting

cable is shipped pre-wired to the flashhead unit. System installation requires

power supply and flashhead mounting, connecting the flashhead cable, suppling

AC power, trigger and a control voltage signal.

An Infrared (IR) Longpass filter eliminates all the visible light from the Xenon

spectrum. The system is ideal as a high intensity, invisible IR source for

applications such as license plate illumination on moving vehicles or nighttime

surveillance. The flashlamp system is housed in a weather resistant enclosure to

provide protection against harsh environments. This strobe can also be used

without the IR filter for any application that requires a large area of intense

illumination.

The unit has electrical discharge energies up to 50J per flash. Intensity can be

controlled with an external reference signal, and a trigger input can synchronize

the flash with a camera.

The spectral output of a Xenon Flashlamp covers the full range from ultraviolet

(UV) through the visible (VIS) to the infrared. The standard IR filter supplied

removes all the wavelengths under 780nm, making the strobe invisible to the

human eye. The spectral output can be changed to match your application by

simply changing the filter. Additionally, two reflector options are available, a

narrow beam (8) or a wide beam (25) configuration.

Please read and follow all safety precautions, such as:

1.2. UNPACKING

If the condition of the outer packaging suggests mishandling has occurred,

examine the 5770 Series strobe for any signs of breakage during shipment. The

Xenon Flashlamp is particularly vulnerable to rough treatment during shipment.

Although the utmost care is taken to preserve the integrity of this item, its fragile

nature makes it susceptible to breakage if the container is mishandled in transit.

If there are any obvious signs of damage, contact the carrier immediately and do

not proceed with the installation. It is recommended that the packaging material

be retained and stored in the event that the unit has to be reshipped.

3.0 INSTALLATION

3.1. MOUNTING

The MVS-5770 Series of strobes are designed for indoor or outdoor use. The

power supply has four (4) mounting holes in the feet that must be secured to a

suitable structure using four (4) ¼-20 threaded screws. It can be mounted in any

orientation. The FlashHead has two ¼-20 threaded, blind mounting holes in it’s

base that must be secured to a suitable structure using two (2) ¼-20 threaded

screws. (see Figure 1). The flashead orientation should be horizontal or pointed

downward at an angle less than 90 degrees from the horizon. All cables must be

supported within 12 inches (30.5 cm) of each unit. Mounting hardware is user-

supplied.

A power disconnect switch or circuit breaker is required on the AC line input. It

must be placed with-in close proximity to the strobe and be with-in reach of the

operator. It shall be marked as the disconnecting device for the strobe.

3.2. SAFETY REQUIREMENTS

The MVS-5770 has features related to safety. For example, to prevent the

possibility of injury from flashlamp breakage, see the section of this manual on

flashlamp replacement.

WARNING!

Because this product is only one component of a system, and, once sold is

exclusively under the control of the user, it has the potential of being used in

a manner outside the intended purpose of Excelitas Technologies

Illumination, Inc. design.

It is essential that the operating specifications and parameters described in Excelitas Technologies

literature and those accompaning other manufacturer’s components be observed and not be

exceeded under any conditions.

To install or operate this product in a manner for which it is not intended may cause personal injury

or death, as well as severe damage to the product and/or other system components.

4.0 OPERATION

4.1. CONNECTIONS

Two terminal strips and a ground lug are used to make the required connections

for system operation. They are located inside the power supply chassis. All

input connections are made to TB1, and output connections to the Flash head

are made to TB2. See Figure 2 & 3 for assignments.

Supply AC power, Trigger and Voltage Reference (Vref) connections to TB-1.

The AC power cable should have three, AWG 16 or larger stranded conductors

with insulation rated to 300 Vac minimum and 85˚C minimum. It shall have an

outside diameter of .30-.47 inches (7.6 – 12 mm). The Vref and Trigger cable

shall be AWG 18 or larger with insulation rated to 300 Vac minimum and 85˚C

minimum. It shall have an outside diameter of .30-.47 inches (7.6 – 12 mm).

Tighten the cablegrip cap nut to 2.25 Nm maximum of torque. The input and

output cables must be supported within 12 inches (30.5 cm) of each unit.

Select the appropriate Vref configuration (Internal or External), and wire per

Figure 2. The system is shipped configured for Internal Vref and the optical

output preset to maximum. To convert to External Vref, move the RED jumper

from TB1-6 to TB1-4, and install Vref signals to TB1-6 & TB1-7 per Figure 2.

Warning: Do not exceed 6.7Vdc Vref signal.

The Interal Vref has been factory set for maximum output energy. The flash rate

must be limited so that the system does not exceed 50 watts.

Power= Energy x frequency (P=Ef) and Energy=½Capacitance x Voltage2

(E=½CV2).

Connect Flashhead cable to TB2 per Figure 3. Match the Flashhead cable wire

colors to TB2 colors labels per Figure 3.

4.2 EXTERNAL VOLTAGE ADJUST

An external reference signal can be used to control the intensiy of the strobe.

The 4 - 6.7VDC Voltage reference signal should be connected per Figure 2. The

lamp voltage may be varied from 600 VDC to a maximum of 1000 VDC.

(V°= V ref x 150).

Warning: Do not exceed 1000VDC.

The flash rate must be limited so that the system does not exceed 50 watts.

Power = energy x frequency (P=Ef) and energy = ½ capacitance x voltage2

(E=½CV2).

4.3 VOLTAGE SETTING VERSUS LAMP LIFE

Lamp life is dependent on the energy per flash. For maximum lamp life, lower

the lamp voltage to a level that will allow sufficient light output for your

application.
