Magnus MRFID S
7 Function
Coded, electronic safety sensor, which is operated by a non-contact coded
actuator.
Safety sensors are suitable for the following ReeR safety relays:
AD SR1 / AD SRM
Admiral
Mosaic M1
MI8O2
MI8
MI12T8
MI16
7.1

Coding variants

The various versions of the safety sensors arise from the different encodings
designated as type keys under point 1.2. Depending on the variant, a corre-
sponding manipulation protection is achieved.
Coded
The safety sensor accepts any Magnus actuator of type MRFID A S.
Type 4; low level coding level according to EN ISO 14119.
Individual
The safety sensor accepts one Magnus actuator of type MRFID A S. This
actuator is configured individually by the safety sensor.
A non-matching actuator in the sensor range will result in an error.
The process for teaching-in a new actuator can be carried out unlimited times
and is descried in detail under "Commissioning" on page 10.
Type 4; high level coding level according to EN ISO 14119.
Unique
The safety sensor only accepts the Magnus actuator supplied. The pair,
consisting of sensor and actuator cannot be separated. If a component was
lost and is no longer functional, both components must be replaced.
Type 4; high level coding level according to EN ISO 14119.

7.2 Safety outputs

The safety sensor provides 2 short-circuit proof PNP safety outputs (OSSD),
which have a max. load of 400 mA per channel.
The safety outputs switch ON under the following conditions:
- the correct actuator is detected in the operating range (safety guard closed)
- a high signal is present at both safety inputs
- the EDM input is set correctly
- no error is detected
The safety outputs switch OFF under the following conditions:
- There is no actuator or the wrong actuator in the detection zone
- Signal is low at one of the two inputs
- An error is detected
The two safety outputs can be connected under the following conditions to the
inputs of a safety controller:
- the input must be appropriate (OSSD signals) for clocked safety signals; the
controller must tolerate test pulses on the inputs (see Technical
specifications on page 27). Please refer to the instructions of the controller
manufacturer.
Wiring examples can be found on page 33.
7.3

Safety inputs

The safety sensor provides 2 safety inputs.
- Connect the safety inputs of +24 V DC for single use of the sensor.
- When using the sensor in a series connection, the safety inputs of the first
sensor can be connected to +24 V DC. The safety inputs of the following
sensors are connected to the safety outputs of the previous sensor. Please
also refer to point 11.1 "Series connection" on page 10.
- Pulses with a duration of max. 900 μs are tolerated on the safety inputs.
Wiring examples can be found on page 33.
7.4

EDM input

The EDM input can be configured as "automatic" or "monitored" (see
number key).
If the EDM input is not required, the "automatic" variant must be selected and
connected to +24 V DC.
EDM input: automatic
For contactor monitoring, the open contactors must be connected to the EDM
input.
For series connection of multiple sensors all EDM inputs must be connected
to +24 V DC. The monitor for the contactors must be connected to the last
sensor of the line.
Wiring examples can be found on page 33.
EDM input: monitors (start button)
Connect the EDM input to an external start button on your machine control.
The EDM input is only recognized as properly set if, after the sensor
activaction and after setting the safety inputs, at least one valid start pulse is
detected. The valid start pulse is detected when after a rising edge, a falling
edge between 30ms and 5s is detected.
Wiring examples can be found on page 33.

7.5 Diagnostic output

The diagnostic output is positive switching, short-circuit protected and trans-
mits the various sensor states with different signals, for example, to a PLC.
The pulsed signals correspond to the timing of the yellow LED.
The various symbols are described in more detail under point 7.6.
