Specifications
- Product Name: R-Safe RRFID
- Model Number: 8541641
- Revision: 0
- Date: 16/02/2023
Package Contents
- RFID Sensor
- Actuator
- Sensor+Actuator
- Safety caps
- Quick installation guide
Precautions
- Before installing the product, it is important to perform a specific risk analysis by the requirements of the Machinery Directive (2006/42/EC). REER guarantees the functional safety of R-Safe RFID but is not responsible for the performance of the system with a tightening torque of 0.8 … 1.5Nm.
Installation
- To guarantee the correct and safe installation and operation of the RFID sensor, please follow these steps:
- Consult the user manual contained at URL: www.reersafety.com/QR/8541641.
- Mount the sensor to the fixed part of the safety gate/door and the actuator to the moving part.
- Use a tightening torque of 0.8 … 1.5Nm for the fixing screws.
- Plug the supplied caps into the housing of the fixing screws as shown in the assembly diagram. These plugs reduce the risk of tampering with the product as indicated in the EN ISO 14119 standard.
- Place the sensor and actuator facing each other with the centering marks at a distance d.
Actuation Direction and Distanced
- Actuation direction 1: 6mm < d < 10mm
- Actuation direction 2 and 3: 2mm < d < 10mm
Connections
- Before supplying power to the product, carry out all connections. Please follow these guidelines:
- The ground connection (0VDC) must be common to all system components.
- Ensure that the connector is screwed in all the way to ensure correct operation of the product.
- The R-Safe RFID sensor must be supplied with a voltage of 24VDC +/- 20% (IEC 60947-5-2).
- Conductor size: 0.25 … 2.5 mm2.
- We recommend the use of separate power supplies for the product and other electrical power equipment (electric motors, inverters, frequency converters) or other sources of disturbance.
- For connections longer than 20m, use cables with a cross-section of at least 0.5mm2 (AWG16), (1mm2 over 50m).

MECHANICAL ASSEMBLY

Before installing the product, it is important to perform a specific risk analysis in accordance with the requirements of the Machinery Directive (2006/42/EC).

REER guarantees the functional safety of R-Safe RFID but is not responsible for the performance of the system in which it is installed.
Respect the correct activation direction described below.
Remove power supply from the product before proceeding with mechanical installation.
It is not permitted to fix sensor and actuator with less than two screws (EN ISO 14119).
Follow the installation rules described in the standard EN ISO 14119.
The use of anti-unscrewing screws is mandatory (EN ISO 14119).
Fasten the devices to the gate using M4 x 20 screws or alternatively 3.5 x 19 cylinderhead self-threading screws with a tightening torque of 0.8 … 1.5Nm.
- Mount the sensor to the fixed part of the safety gate/door and the actuator to the moving part.
- At the end of the assembly, plug the supplied caps into the housing of the fixing screws as shown in the assembly diagram. These plugs reduce the risk of tampering with the product as indicated in the EN ISO 14119 standard.
- Place the sensor and actuator facing each other with the centering marks at a distance d corresponding to:

Actuation direction: 1: 6mm < d < 10mm | Actuation direction 2 and 3: 2mm < d < 10mm (See following pictures for actuation direction and distance d) $REER-8541641-RFID-Safety-Switch-FIG-1 $4$$

Multiple systems

In the case of applications involving multiple sensors mounted close together, a minimum distance L = 150mm between the sensors must be observed in order to avoid interference.

CONNECTIONS

Carry out all connections before supplying power to the product.
The ground connection (0VDC) must be common to all system components.
Make sure that the connector is screwed in all the way to ensure correct operation of the product.
The R-Safe RFID sensor must be supplied with a voltage of 24VDC +/- 20 % (IEC 60947-5-2).
Conductor size: 0.25 … 2.5 mm2.
We recommend the use of separate power supplies for the product and for other electrical power equipment (electric motors, inverters, frequency converters) or other sources of disturbance.
For connections longer than 20m, use cables with a cross-section of at least 0.5mm2 (AWG16), (1mm2 over 50m). $REER-8541641-RFID-Safety-Switch-FIG-1 $7$$
