mode

for items and settings that are frequently reconfigured, and the

‘

Operation protection

 You can use the ‘key lock function’to protect these operations. (Refer to p. 56.)

Key lock function

This function can be used to prevent the operator from accidentally changing the sensor settings.

Automatic interference prevention function

 To operate the automatic interference prevention function, you need to install the amplifiers so that they are

directed against each other and carry out optical communication.

The automatic interference prevention function allows up to four sensor heads to be installed so that they are

directed against each other.

(However, the automatic interference prevention function cannot be used in H-SP mode.)

Output switching

 Set the sensing mode (PRO6) for output 1 to normal mode beforehand.

In modes other than normal mode, this is fixed at output 1.

 Press the MODE key for more than 2 seconds when in NAVI mode. If Output 1

has been selected, the Select 1 indicator (yellow) lights up. If Output 2 is being

selected, the Select 2 indicator (yellow) lights up.

RUN :

Normal Sensing Operation

TEACH : Teaching Mode

This indicates normal sensing operation. Threshold value (green) and incident light

intensity (red) are displayed in real time. Manual fine adjustment of the ‘threshold

value’can be performed during normal sensing operation.

The ‘threshold value’can be set with any of the 3 teaching methods, ‘2-level

teaching’, ‘limit teaching’and ‘full-auto teaching’.

This mode sets the ‘threshold value’by utilizing teaching.

When using normal mode

Turn the jog switch to either ‘’(left) or ‘’(right) to increase / decrease the

threshold value.

If there are no key operations after a certain period of time or if the MODE key is

pressed (to change to TEACH), the digital display (green) will blink and the setting

will be confirmed.

2-level teaching is a method of setting the threshold value by teaching the

amplifier two different status conditions - sensing object present and sensing

object absent.

The ‘threshold value’is usually set using this method.

Refer to p. 11 ~ for setting procedure

Each time the jog switch is pressed, the display switches between the ‘’threshold value 1 and ‘’

threshold value 2.

After ‘’or ‘’is displayed, the respective threshold value will be displayed.

If you turn the jog switch to ‘’when the output 1 ‘’is displayed, the following will be displayed.

This method is used to set the threshold value while the sensing objects are still

moving on the production line, without stopping the production line.

When using window comparator mode

The ‘threshold value’can be set with any of the 3 teaching methods (‘1-level

teaching’, ‘2-level teaching’and ‘3-level teaching’). By setting two ‘threshold

After teaching, P-1, P-2 and P-3 are automatically assigned in ascending order to

‘A’‘B’, and ‘C’.

This sets the ON / OFF levels with any of the 3 teaching methods (‘1-level

By adjusting the hysteresis, the irregular sections of sensing objects with

irregularities are canceled out so that stable sensing is possible.

If the response time is changed in differential

mode, the maximum sensitivity (minimum threshold

as follows in teaching mode. The threshold value

can be changed using the threshold value fine adjustment function. Refer to
