RFID 3SE63 contactless safety switches meet the highest safety requirements, SIL3 or Cat. 4, for monitoring the positions of movable protective devices.

An RFID safety switch consists of a coded RFID switch with an 8-pole M12 connector plug and an identical RFID actuator.

The switch is available in several versions:

• Family coded with M12 plug or with additional 18 N magnetic catch as an option
• Individually coded, programmable once, with M12 plug or with additional 18 N magnetic catch as an option
• Individually coded, programmable more than once (an unlimited number of times), with M12 plug or variant with additional 18 N magnetic catch

The actuator is therefore available in two versions:

• Standard
• With 18 N magnetic catch

The magnetic catch keeps doors and flaps closed with permanent magnets.

Mounting and maintenance

Various options for mounting save on enclosure variants:

• Mounting of the switch on the right or left side possible
• the actuator can be mounted on all sides

Quick and easy mounting by thanks to universal mounting holes

• Standard gauge/holes for 3SE6 magnetically operated switch
• Fine adjustment thanks to slotted holes

Little adjustment or maintenance required

• Threshold indication by LED switch for quick and easy adjustment during installation and maintenance
• Molded switch allows it to be used as an end stop for small and medium-sized doors

Note:

• Keep metal parts and cuttings away from the vicinity of the switch
• Minimum distance between two switches 100 mm

Optional accessories (mounting)

• Covers for sealing mounting holes, also suitable for tamper-proofing screw fixings
• Spacers (approx. 3 mm high) to facilitate cleaning under the installation surface when using high-pressure cleaners, for example

Coding

Family coded

These safety switches are delivered ready to use, i.В e. no programming is necessary.

Individually coded, programmable once

The assignment of safety switch and actuator thus created is irreversible.

The actuator is programmed simply by routine during startup, thus permanently preventing any form of tampering by means of a replacement actuator.

Individually coded, programmable several times

The procedure for programming a new actuator can be repeated an unlimited number of times. When a new actuator is programmed the previous code becomes invalid. A protected coding process allows new actuators to be programmed for service purposes.

After this, a ten-minute lockout provides enhanced tamper protection. The green LED flashes until the lockout time has ended and the new actuator has been detected. If the operational voltage is interrupted during this time, the ten-minute guard time is restarted.

Programming procedure for individual coding

1. Apply operational voltage to safety sensor

2. Move actuator into detection range: red LED lights up, yellow LED flashes (1 Hz)

3. After 10В s it changes to a shorter flashing frequency (3В Hz). In this state switch off operational voltage.

4. After the next time the operational voltage is switched on, the actuator is detected again to activate the programmed actuator code. The activated code is thus stored permanently.

Diagnostics

The RFID safety switch indicates its operating state including faults by means of the LED indicator in the switch and the short circuit-resistant diagnostic output. The signals can then be used for central displays or non-safety-related control tasks.

There are two diagnostics functions:

• Crossover monitoring
• Open-circuit monitoring
• External voltage monitoring
• Ambient temperature too high
• Wrong or defective actuator
• Switching interval threshold identification with LED indication

The signal combination "diagnostics output switched off" and "safety outputs still switched on" can be used to move the machine into a controlled stop position.

Any crossover or a fault that is not currently compromising the safe operation of a safety switch results in the disconnection of the safety channels after a 30 minute delay. However, the diagnostics output switches off instantaneously.

Mode of operation of the diagnostics LEDs

The safety switch indicates not only its operating state, but also faults by means of LEDs in three colors at the ends of the RFID switch.

• The green LED indicates readiness for operation when the control supply voltage is connected.
• The yellow LED indicates that there is an actuator in detecting range. If the actuator is in the switching interval threshold, this is indicated by flashing. This flashing can be used to identify a change in the distance between sensor and actuator at an early stage (e.В g. as a result of the sagging of a protective door). The installation should be tested before the distance increases further, the safety outputs switch off and the machine stops.
• The red LED indicates the individual causes of the fault by means of defined flashing frequencies.
