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.

Time chart

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 intensity is rising.

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

PRO2 Mode

6-1. PRO2 Mode Functions and Settings

Display Switching Function

Refer to p. 32 for setting procedure

PRO2 mode is used mainly for selecting the detailed configuration of the digital display and incident light intensity data processing. * Output 1 and output 2 will both be changed to the same settings.

The settings can be carried out in either output 1 mode or output 2 mode.

In RUN mode, the digital display is fixed to either incident light intensity, % or peak hold / bottom hold display, but you can select it to be a variable display. (Rising / trailing differential mode allows only incident light intensity display.) * The factory setting is for ‘no digital display switching’. * Window comparator mode and hysteresis mode are the only modes that do not

have digital display switching, so that display switching cannot be used in these modes. (1_SL and 2_SL can be switched.)

Note: The incident light intensity display can display a maximum value

of 4,000 in H-SP (ultra high-speed) mode and FAST (highspeed) mode. In STD (standard) mode and U-LG (ultra longrange) mode, it can display up to a maximum value of 9,999.

● Peak hold / Bottom hold display

This function displays the peak and bottom numerical value of the incident light intensity.

● Percentage display

This function displays the incident light intensity within a range of 0P (0 %) to 999P (999 %), based on the threshold value as a standard.

This function saves amplifier settings. Up to 3 sets of settings can be saved in ‘ ’, ‘ ’ and ‘ ’. You can select whether the settings for only one amplifier are saved or the settings for all amplifiers on the right side that are connected via optical communication are saved all in a single step.

Data bank

PRO3 mode can load settings from the data bank and can save settings to the data bank.

The LS-400 series incorporates an internal memory for storing setting. Three different sets of settings can be stored within the data banks, in channels 1 ( ) to 3 ( ). These settings will not be deleted, unless they are intentionally overwritten by the data bank save setting function.

Setting within the data bank will not be deleted, even when a reset is performed using the ‘9-4. Setting Reset Function’ from ‘PRO5 Mode’ on p. 50.

Optical communication

When the collective data bank load / save function or copy function is used via optical communication, loading / saving or copy of the setting can be carried out only to the amplifiers (sub units) connected on the right side of the amplifier (main unit). However, if the amplifier (sub unit) is being connected (the indicator blinks), PRO mode is being set or the transmission change to permit / not to permit function is set to ‘not to permit’, loading / saving or copy is not carried out. Furthermore, the sensing operation stops during optical communication.

(

To copy the same settings to the 4th and subsequent channels: Use the 4-channel data bank load / save function and the copy function.

To copy the same settings to the 1st and subsequent channels: Use the 1-channel single step data bank load / save function and the copy function.

PRO4 Mode

8-1. PRO4 Mode Functions and Settings

PRO4 mode is mainly used for configuring communication with sub units and external input modes.

By utilizing the optical communications function, the settings information from the operating amplifier can be copied to other connected amplifiers. (Except for data bank contents) However, the 0-Adjust setting function and transmission change to permit / not to permit function will not be copied. As well, in amplifiers in which the optical communications settings change function has been locked, copying will not occur.

When attempting to perform single step load / save / copy operations using the data bank load function and data bank save function from PRO3 mode, and copy function from PRO4 mode, if the transmission change has not been permitted, then only the specified amplifier will be locked. Therefore single step load / save / copy operations will be disabled. * The factory setting is ‘Lock OFF’.

Selects ‘emission halt’, ‘full-auto teaching’ or ‘limit teaching’ using external input wires.

Note: Output operations are undefined only for the response time.

When the output signal is being received by a PLC or other device, set the timer to 2 ms

Note:

After teaching is finished, output operations are undefined only for the response time. When the output signal is being received by a PLC or other device, set the timer to the sensor response time or longer. The incident light intensity at the instant teaching is recognized is set as the standard threshold value.

Notes: 1) Pass the sensing object past the sensor once while an input signal is being input.

2) After teaching is finished, output operations are undefined only for the response time. When the output signal is being received by a PLC or other device, set the timer to the sensor response time or longer.

This function is used for not storing the threshold value obtained from external input teaching into the EEPROM. It prevents unnecessary writing to the EEPROM. * Note that when the power is turned off, the threshold value becomes the value

that was last stored in memory.
