Sunx FX-D1 - Full Auto-Teaching; Maximum Sensitivity Setting; Fine Adjustment; Limit Teaching

To Previous Page

٨ Full auto-teaching is used when it is desired to set the threshold value without

stopping the assembly line, with the object in the moving condition.

In case of full auto-teaching

࡮

Set the mode selection switch to 'RUN'.

The threshold value does not change even if the jog switch is operated.

࡮

If teaching is accepted, the read incident light intensity is displayed for 0.5 sec. approx., and the threshold

value is set to the middle value of the incident light intensity levels in the object present and object absent

conditions. After that, the judgement on the stability of sensing is displayed for 2.5 sec. approx.

After this, the threshold value is displayed.

࡮

In case stable sensing is possible: ' ' is displayed.

In case stable sensing is not possible: ' ' is displayed.

࡮

Set the mode selection switch to 'SET'.

The present threshold value is displayed.

࡮Set to either Output 1 or Output 2 by turning the jog switch to the '+' or the '

side.

࡮Set the fiber within the sensing range.

࡮Set the mode selection switch to either 'RUN' or 'MODE'.

࡮Press the jog switch continuously for 3 sec. or more with the object moving on

the assembly line.

࡮

' ' is displayed on the LCD display. Release the jog switch when the object has

passed.

Set the mode selection switch to either 'RUN' or 'MODE'.

Set to either Output 1 or Output 2 by turning the jog switch to the '+' or the '

' side.

Set the mode selection switch to 'SET'.

Press the jog switch in the condition when there is no object or background body.

If teaching is accepted, ' ' is displayed on the LCD display.

Once again, press the jog switch in the condition when there is no object or background body.

Set the mode selection switch to 'RUN'.

Note:

Please take care that, if the sensor is set to max. sensitivity, it becomes weak against extraneous light,

noise and optical interference.

In case of fine adjustment

࡮

Set the mode selection switch to 'RUN'.

The threshold value does not change even if the jog switch is operated.

࡮

Set the mode selection switch to 'SET'.

The present threshold value is displayed.

࡮

In case the threshold value is to be increased (sensitivity to be reduced), turn the

jog switch a little to the '+' side to increase the threshold value slowly. If the jog

switch is turned fully to the '+' side, the threshold value increases rapidly.

In case the threshold value is to be decreased (sensitivity to be increased), turn

the jog switch a little to the '

' side to decrease the threshold value slowly. If the

jog switch is turned fully to the '

' side, the threshold value decreases rapidly.

SETTING OF EACH MODE

In case only a part of the settings are to be changed, set the mode selection switch

to 'RUN', at the appropriate time, in the middle of the above procedure to make only

the required changes.

࡮Press the jog switch at the output operation desired to be set.

࡮Turn the jog switch to either the '+' or the '

' side. The bar display

alternates between Output 1 and Output 2.

(The bar display on the extreme left blinks.)

࡮Press the jog switch at the output desired to be set.

٨ FX-D1 series incorporate an ON-delay timer, which is useful when sensing only

objects with a long passage time, and an OFF-delay timer, which is useful when

the sensor is connected to devices having a slow response time. The timer period

can be selected from four values: 40ms, 100ms, 200ms and 500ms.

Please refer to ' SETTING OF EACH MODE' for the setting method.

٨ Since the FX-D1 series incorporate an interference prevention function, up to 3

sets of fibers can be mounted close to each other by setting different emission

frequencies. Further, close mounting is also possible along with fibers which are

fitted to the fiber sensor amplifiers, FX-A1 series and FX-M1 series.

Please refer to ' SETTING OF EACH MODE' for the setting method.

However, note that the response time varies with the emission frequency as given below.

Note: Do not set the threshold value when interfering light is incident.

Correct incident light intensity cannot be taught in this condition.

Description

٨ This is the method of setting the threshold value by teaching only the object absent

condition (incident light stable condition). This is used for detection in presence of a

background body or for detection of small objects.

If the jog switch is pressed continuously for 3 sec., or more, full auto-teaching is done.

If the mode selection switch is changed to 'RUN' when '˴˴' is being displayed on the

LCD display, the incident light intensity taught at Step Ԝ is not recorded.

PERCENTAGE DISPLAY

After setting the threshold value, the current incident

light intensity can be expressed as a percentage of the

threshold value so that the degree of margin can be

confirmed at a glance. If the jog switch is pressed when

the mode selection switch is set on 'RUN', the display

changes from absolute value to percentage value, and

0 to 999% is displayed. However, % (percent) is

expressed by ' ' and fractions are rounded off.

If the jog switch is pressed once again, the

display returns to absolute value.

Further, in case percentage display is desired

when the power supply is switched off, and then,

on again, change the mode selection switch once

to 'SET' or 'MODE', and then, set it back to 'RUN'.
