Overview
non-contact RFID safety switch with maximum tamper protection
RFID 3SE63 non-contact safety switches comply with the
highest safety requirements, SIL 3 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 hinge switches 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
•
The actuator can be mounted on all sides
Quick and easy mounting thanks to universal mounting holes:
•
Standard gauge/holes for 3SE6 magnetically operated
switches
•
Fine adjustment thanks to slotted holes
Little adjustment or maintenance required:
•
Threshold indication by LED display on the switch for quick
and easy adjustment during mounting 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. 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 opera-
tional 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 10 s it changes to a shorter flashing frequency (3 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 proof diagnostics 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 display
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 function of a safety switch results in the disconnection of the
safety channels after a 30-minute delay. However, the diagnos-
tics output switches off instantaneously.
