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 detection
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. 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.
■
Benefits
•
Maximum tamper resistance by means of individual coding of
switches and actuators at the highest safety level
•
Plastic enclosure with integrated connector
•
Two solid-state short-circuit proof safety outputs, each
250 mA
•
Integrated crossover, open circuit and external voltage
monitoring, with series circuit as far as the control cabinet
•
Safety and diagnostics signals can be connected in series
•
Series connection of safety circuits in Cat. 4 / PL e / SIL 3
•
LED status indication including switching interval threshold
indication for quick and easy adjustment during installation
and maintenance
•
Short-circuit proof conventional diagnostics output
•
Optional version with magnetic catch for interlocking hinge
switches or small doors even when de-energized
•
Highly rugged thanks to the use of tested enclosure materials,
resistant to aggressive cleaning products, with a degree of
protection of up to IP69(K)
IP69 does not automatically mean that it can be used
outdoors. The devices must be installed with corresponding
protection for this purpose. UV radiation additionally affects
the enclosure
•
Fine adjustment thanks to slotted holes
•
Little adjustment or maintenance required
•
Molded switch allows it to be used as an end stop for small
and medium-sized doors
■
Application
RFID non-contact safety switches are designed for use in safety
circuits, and are used to monitor the positions of movable
protective devices. They monitor the positions of rotating,
laterally sliding or removable protective devices using the coded
electronic actuator.
Their high degree of protection (IP69K) and the use of cleaning-
product-resistant materials means that these switches are
optimized for use under extreme environmental conditions.
Their electronic operating principle makes these switches ideal
for metalworking machinery.
The switches have a larger switching interval and switching
displacement than mechanical switches, improve the mounting
tolerance of the protective door, and offer a wide range of
diagnostics options.
The RFID switches can be connected to all standard evaluation
units suitable for solid-state inputs and in which the built-in
crossover monitoring function can be deactivated, e.g.:
These safety categories can be achieved in safety circuits:
•
Category 4 according to EN ISO 13849-1
•
PL e according to EN ISO 13849-1
•
SIL 3 according to IEC 61508
