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

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.

Extends the output signal for a fixed period of time.
This function is useful if the output signal is so short that the connected device cannot
respond.
Neglects short output signals.
As only long signals are extracted, this function is useful for detecting if a line is clogged, or
for sensing only objects taking a long time to travel.
Outputs a fixed width signal upon sensing.
This function is useful when the input specifications of the connected device require a
signal of fixed width. Of course, it is also useful for extending a short width signal to a
desired width.

For L-ON, output is ON for a constant period of time when the incident light
intensity is rising.
For D-ON, output is OFF for a constant period of time when the incident light

The ‘threshold value’can be set by utilizing three kinds of teaching, whichever ‘2-level teaching’, ‘limit teaching’or
‘full-auto teaching’.
