Cascade Connection

Multiple EN devices (models with cascading functionality) can be connected in a cascaded manner to monitor the opening and closing status of multiple doors, windows, or similar structures on the same machine.

1. Cascading of Passive Models: Multiple passive model devices (ENQQC models) can be directly connected in series and then connected to the safety signal circuit of a safety relay to achieve cascading. The specific connection method can be referred to in the connection example: “Connection Example Diagram 2”.
2. Cascading of Active Models: For the ENQQFT20L or ENQQMT20L models, when cascading, the OSSD1 and OSSD2 of the upper device should be connected to the Safety Input 1 (SI1) and Safety Input 2 (SI2) of the next device, respectively. The OSSD1 and OSSD2 of the last device in the cascade should be connected to the safety inputs SI1 and SI2 of the safety relay or other external devices. The safety inputs SI1 and SI2 of the first device should be connected to the 24VDC supply. The specific connection method can be referred to in the connection example: “Connection Example Diagram 3”.

Connection examples

1. Example 1: Active models connect to the safety relay example

Example 2: passive models cascading connect example

Example 3: Active Models cascading connect to the example

Note: Different circuit structures have different functional safety levels, which need to be selected according to the actual requirements of the site. For details, please consult our customer service.

RFID Actuator Matching

RFID actuators come in two types: universal coding and independent coding. Universal coding switches are pre-matched with actuators at the factory, and typically do not require re-matching when replacing different actuators. However, for independent coding non-contact switch kits, the switch body will only work with the matched independent coding actuator during operation.

If the actuator code does not match the previously matched code, the switch body will fail to operate. To replace with another independently coded actuator, the switch body and the new actuator must be matched.

RFID Actuator Matching Method:

1. Connect the switch body to the power supply (-3M: Red wire to 24VDC, Black wire to 0V; -M12-8: PIN2 to 24VDC, PIN7 to 0V). Connect the actuator pairing enable (-3M: Yellow wire; -M12-8: PIN1) to 24VDC.
2. After powering on the switch, the green LED will flash, indicating that the pairing mode has been entered. Bring the actuator close to the switch body to complete the matching.
3. Once the pairing is complete, the LED indicator on the switch will display a steady orange light, indicating that the pairing is successful.
4. Remove the actuator, disconnect the power and actuator pairing enable lines, restore the normal working wiring, and power on again to use. After rebooting, if the switch does not detect the actuator, the LED indicator will display alternating red and green flashes. When the actuator is brought within the detection range, the switch’s LED light will turn to a steady
   green light, indicating that the actuator has been detected and the switch is operating normally.
5. After rebooting, if the switch does not detect an actuator, the LED indicator will display alternating red and green flashes. When the actuator is brought within the detection range, the switch’s LED light will turn to a steady green light, indicating that the actuator has been detected and the switch is operating normally

Safety Precautions

• Professional Handling: The design, installation, commissioning, and maintenance of the product should be carried out by qualified technical personnel. Failure to do so may result in personal injury or equipment damage.
• Electrical Safety: To avoid electric shock or fire, ensure the equipment power is turned off before installation, removal, wiring, maintenance, or inspection of the switch.
• Installation Location: Do not install the actuator in locations where it may come into contact with the human body to prevent potential injury.

Installation Instructions

• Safety Level: By using a safety relay module (with a dual-channel safety relay configuration), the product can meet the safety level requirements of CAT 4 (EN ISO 13849-1).
• Matching Components: The non-contact switch and the actuator are designed for use together. During installation, configuration, use, and maintenance, ensure that the corresponding matching actuator model is used. Do not use non-matching models.
• Power and Load: Do not install or remove the encoded magnetic switch while the power is on. Do not exceed the rated load limits for the corresponding switch model. It is recommended to use a fuse in series to prevent damage due to misuse.
• Impact Protection: If the impact force during door closure exceeds 300 m/s² (approximately 30G), it may cause switch failure. It is recommended to install a door stop mechanism (e.g., a door bolt) to prevent direct impact between the non-contact switch and the
  actuator.
• Product Integrity: To ensure the protective performance of the product, do not disassemble it after purchase. If mechanical damage to the enclosure is detected, especially in damp environments, stop using the product immediately and replace it.
• Storage Conditions: Do not store the switch in dusty, damp, or organic gas environments, or areas exposed to direct sunlight.
• Magnetic Interference: Do not install magnetic encoded switches (ENQQC, ENQQM series) in environments with strong magnetic interference. For such environments, consider using
• RFID-enabled contact switches (ENQQF series) or consult a sales advisor for
  alternative solutions.

Installation Notes

Installation Torque

Shim Block Usage: The product is equipped with four Shim blocks for fixing holes. It is recommended to use these blocks when tightening the screws to ensure that the switch and actuator are installed horizontally and securely.

Tool and Torque Requirements: Use a non-magnetic screwdriver during installation to avoid interference with the product. The tightening torque should not exceed 1 Newton meter (1 N·m).

Cable Wiring Precautions

• Avoid Excessive Tension: Excessive tension during wiring can cause the cable to break. When routing and securing the cable, allow for a small amount of slack to accommodate movement.
• Handle Cables with Care: Do not pull the cable forcefully, especially at the switch connection point. Doing so may cause the cable to break or the cable sheath to dislodge, which could compromise the protective performance and lead to other failures.

Magnetic Non-Contact Switch Operating Area

• SAO (Safe Operating Distance for Activation): The distance at which the safety output is guaranteed to be activated.
• SAR (Safe Operating Distance for Release): The distance at which the safety output is guaranteed to be deactivated
