Chapter 1 The strobe instrument function

The strobe is also called a strobe camera or tachometer, strobe

light, etc. The strobe itself can emit a short and dense flash. Adjust the

flash frequency of the strobe, make it with the rotation of the measured

object (or movement speed close to (or synchronization, although the

measured object in high speed movement, but it is slow movement or

relatively static, using this kind of visual temporary phenomenon,

human eye can easily observe the high speed movement object surface

quality and running condition, the strobe flash frequency is the detected

object (e. g., motor) speed or movement frequency.

Figure 1. Visual inspection Figure 2. Use of strobe lights

The duration of the flash flash and the relative brightness of the

light can affect the sharpness of the image. The longer the flash

duration, the more blurred the image.

It is recommended that the strobe flash brightness is 4 times the

brightness of the surrounding environment.

Chapter 3 Introduction to working Methods

3.1 Internal trigger mode

The internal trigger mode refers to the strobe signal provided

inside the strobe, and the flash frequency can be adjusted by the button

on the operation panel.

3.2 External trigger mode

The external trigger working mode is provided by the external

photoelectric eye, Hall switch / proximity switch, photoelectric encoder

and other sensors, and the strobe flashes according to the signal

frequency to realize the automatic tracking function. The external

trigger mode is divided into four working modes: single pulse,

perimeter length, encoder and gear.

In the single-pulse operation mode, the strobe detects an external

signal and flashes once, which is generally used when the printing

pattern movement frequency is consistent with the signal frequency

detected by the sensor. For example: with the color mark sensor

(photoelectric eye) to detect the color mark of the printing pattern, each

after a pattern, the sensor detected a signal, strobe flash once, to

achieve automatic tracking.

When the signal detected by the strobe is not consistent with the

operating frequency of the pattern, the circumference length, encoder

and gear mode can be selected according to the connected sensor.

Parameters of the perimeter standard length mode: perimeter C,

standard length d

C-represents the circumference,refers to the length corresponding

to two consecutive signals, in mm, maximum 999.9mm; for example, a

magnet signal on the driven roller detected by Hall sensor, a signal is

generated for each turn of the driven roller, when C is set to the

circumference of the driven roller.

The d-represents the distance between two consecutive identical

printed patterns, the starting position of the first pattern to the second

pattern in mm and maximum 999.9mm.

Parameters of the encoder mode: standard length d

Mode of d-same length.

Parameter of the gear mode: number of teeth t

Teeth number t-represents the number of teeth corresponding to the

distance between two identical patterns, set to range from 10 to 200.

4.6 Estimate the flash frequency

When using the internal trigger operation mode (F00), if you do

not know which flash frequency value to adjust to, it can be calculated

according to the following formula:

flashing rate

: Trigger frequency in the strobe device, unit: time / minute;

: Running speed of the machine in m / min.

: The distance between two consecutive identical printing

patterns, that is, the starting position of the first pattern to the starting

position of the second pattern, in unit: mm;

For example: speed =100 m / min, pattern spacing =50 mm;

trigger flash frequency n = (10050) 1000=2000 times / min. After

adjusting the frequency of the strobe to 2000, the pattern is seen

standing still or moving slowly, and then fine-tune the situation until

the pattern is relatively static.

Chapter V. Description of the external interface

5.1 External trigger wiring

The external trigger interface pin is defined as follows:

 1 pin —— + 12V —— strobe inside the DC12V ground

 2 pins —— GND —— strobe internal DC12V power supply
 3 pins —— A- —— triggers the negative input of the signal A,

connected to the photocoupling negative end of the strobe

 4. The plus input of the trigger signal A is connected to the

photocoupling plus end of the strobe

The connection between the four-core air socket and the strobe

circuit is shown in the figure below:

Chapter 7 Disposal

For the disposal of batteries in the EU, the 2006/66/EC directive of the
European Parliament applies. Due to the contained pollutants, batteries must not
be disposed of as household waste. They must be given to collection points
designed for that purpose.

In order to comply with the EU directive 2012/19/EU we take our devices back.
We either re-use them or give them to a recycling company which disposes of
the devices in line with law.

For countries outside the EU, batteries and devices should be disposed of in
accordance with your local waste regulations.

If you have any questions, please contact PCE Instruments.
