● Work Mode Selector Switch
| No. | Name | OFF Side | ON Side |
| 1 | Projection Frequency Conversion | Frequency A | Frequency B |
| 2 | Work Indicator Light Mode Selector Switch | Lights up when entering | Turns off when input |
| 3 | Work Indicator Light Mode Selector Switch | Continuous Lighting | Blink |
| 4 | Work Indicator Light / Projector Stop Switch | Work Indicator Light Input | Stop Light Input |
(2) Work Indicator Light Operation Selection
● The operation of the work indicator light can be used as a mode selection switch for the work indicator light.

Work Indicator Light Input Signal Conditions
| Output | Signal | Signal Conditions |
| NPN Output Type | Low | 0 to 2 V |
| High | 5 to 30 V or open circuit (If open circuit, please insulate the wire) | |
| PNP Output Type | Low | 0 to 2 V or open circuit (If open circuit, please insulate the wire) |
| High | 8 V~+V |
● When using the work indicator light as a large work status indicator
By setting the 4th operation mode switch to the OFF position and connecting the input (pink) on the emitter to the output (black) on the receiver, the work indicator light can be used as a large work status indicator.
| Work Indicator Light Operation Mode Switch | When Light Enters | When not illuminated |
![]() | Light up![]() | Off![]() |
![]() | Off![]() | Light up![]() |
![]() | Light up![]() | Blink![]() |
![]() | Off![]() | Blink![]() |
(Note 1): If you use the operation indicator as a large work status indicator, please make sure to set the 4th operation mode switch to the OFF position. If it is set to ON, the operation indicator will not light up or flash.
● Emission Stop Function
When the 4th operation mode switch is set to ON and the input (pink) on the emitter is High (PNP output type: Low), emission stops. Since the output can be set to ON/OFF when there is no detected object, this function can be used for initial detection. It can be determined as normal when the output tracks the ON/OFF input according to the light projection. If it does not track, it can be determined as a sensor abnormality.

(3) Anti-interference function
Since different emission frequencies are set, two sets of sensors can be installed close to each other as shown below. You can check the projection frequency by the number of LEDs lit on the projector indicator.

| Operating Mode Switch Status | Floodlight Display Lamp (Floodlight) | |
| Sensor A | Frequency A | 1 LED lights up |
| Sensor B | Frequency B | Two LEDs are lit |
(2) About Optical Axis Adjustment
a) Place the emitter and receiver facing each other in a straight line.
b) After properly connecting the cables, turn on the power.
c) Move the transmitter up, down, left, and right, and use the operation status indicator (red) to determine the light receiving range. Then, set the transmitter at the center of this range.
d) Move the transmitter up, down, left, and right in terms of angle, and adjust in the same way as above.
e) Adjust the receiver angle in the same way.
f) Check if the stable light indicator (green) is on.
g) Block the optical axis with the actual object to be detected and confirm if it is working properly.
