Safety light curtains manual
The light curtain is used to protect the dangerous area around the machine and equipment. When at least one beam is blocked, the TBN light curtain will output a designated signal to notify the machine and equipment to take corresponding measures.
The light curtain can be used alone, or can be combined with safety modules such as safety relays, light curtain relays, emergency stop switches, etc. to form a more complex control system to achieve alarm when entering dangerous areas or interlock with the safety protection system of the equipment.

Wiring instructions:
1. Connect the brown wire of the transmitter to the brown wire of the receiver, and then connect the power supply DC 24 V.
2. Connect the blue wire of the transmitter to the blue wire of the receiver, and then connect the power supply 0 V.
3. The black wire of the transmitter is connected to the black wire of the receiver, and the white wire of the transmitter is connected to the white wire of the receiver.
4. The two connected black wires output NPN signals, and the two connected white wires output PNP signals.
Debugging :
Without shading ,the red light is off ,the green light is on.
Installation Precautions
When two or more sets of safety light curtains are installed adjacent to each other, the safety light curtains are likely to interfere with each other. They should be installed with reference to the following diagram to prevent the light emitted from the illuminator from illuminating another set of adjacent light receivers.
When the two ends or sides of the light curtain are too close to the smooth operating surface or other objects that can reflect light, the infrared light emitted by the light curtain transmitter may be refracted to the receiver (as shown in the figure below), resulting in the failure of the light curtain protection function;
Solution：
① When installing the light curtain, try to keep the distance between the light curtain and the smooth (reflective) operation table above 30mm;
② Improve the smooth operation surface, such as filming or matt treatment.
