7.7 Boundary area monitoring

If the actuator is in the boundary area of the switching distances with corre-
sponding offset values of the sensor, it is transmitted to a PLC or indicated by
the LED (see point 7.6).

9 Assembly
- Safety sensor and actuator
do not use as a beat

external fields can affect switching distances

- Installation of the safety sensor and the associated actuator is allowed only
when de-energized.
- Make sure that the markings on the sensor and actuator face each other
congruently.
- The mounting position is arbitrary. However, security sensor and actuator
must be mounted parallel and opposite each other.
- Note the specified installation tolerances and the approved control options.
The specified operating distance around the free zone must be maintained
free of electrically and magnetically conductive metallic materials.
Matching spacer plates for mounting on metal parts are available
under the order no. MRFID SP B (10 mm) from ReeR.
- The mounting distance between two systems of the safety sensor and
actuator must be min. 15 cm.
- Attach safety sensor and actuator to the protective device so that they
cannot be removed.
- Use only M4 screws with flat head (e.g. M4 cheese head screws ISO 4762)
for installation of the safety sensor and actuator. Tightening torque max.
0.7 Nm. Use non-ferromagnetic material (e.g. brass) screws.
We recommend using the screw covers included to secure the
mounting screws against easy disassembly.
- The safety sensor must be mounted on flat surfaces.
- The connecting cable of the safety sensor must be protected against
mechanical damage.
- Consider the requirements of EN ISO 14119 during installation.

- Also consider the requirements of EN 60204-1, in particular regarding the proper
laying of cable. It is recommended to lay the sensor cable so that it is covered.

10 Adjustment

- The stated operating distances (see Technical specifications from page 27)
are only valid for mounting on non-metallic material if the safety sensor and
actuator are mounted in parallel opposite each other. Other arrangements
may lead to different switching states.
11 Electrical connection
The electrical connections must be made without voltage applied
and may be performed by authorized personnel only.
- Connect the safety sensor according to the specified wire colors and pin
assignment (see "Circuit diagram and pin assignment" on page 31).
Matching cable sets (type no.: MRFID EC...C..) and an installation
wrench are available directly from ReeR for safety sensors with
connectors. We also offer options for easy wiring in series
connection. T-distributor (Item no.: MRFID T...) and connect- ing
cable (Item no.: MRFIDEC.L-MRFIDEC.S). (For more information
see point
- Both safety outputs must always be evaluated to ensure safety.
- Since the diagnostic output is not a safety output, it may not be
used for safety-relevant information and monitoring functions.
- Make sure that the required minimum input voltage of the downstream safety
relay is not undershot. Observe the voltage drop at the safety sensor and the
connecting cable.

11.1 Series connection

The safety sensors enable a series connection with up to 30 sensors while
achieving up to PLe with correct wiring.
For a series connection please note that a time delay accumulates for each
additional sensor. The relevant technical specifications can be found in the
table from page 27.
Configuration of EDM input -> see point 7.4
Wiring examples can be found on page 33.
The maximum number of safety sensors, as well as the total length of the
sensors line is load-dependent.
Increasing line length and increasing current load (load + sensors) in the
series connection increases the system voltage drop.
If the level voltage falls below the permissible value of 21.6V, an
additional power supply must be admitted. The ReeR T-distributor MRFID TC
A can be used for this purpose.

11.2 Information about power supply

- The sensor must be directly or indirectly powered with a SELV/PELV
power supply.
- For use and applications complying the requirements
must be classified "for use in class 2 circuits".
1) Notice regarding the scope of the UL approval: The devices have been
tested in accordance with the requirements of UL508 and CSA/C22.2 no. 14
(protection against electric shock and fire).
11.3 Note for use in safety control systems
- Do not use external test pulses.
The device generates its own test pulses on the safety outputs. A downstream
control system must be able to tolerate these test pulses, which may have a
length up to 300 s. Depending on the inertia of the connected device
(controller, relay, etc.), this can lead to short switching processes.
- The inputs of a connected evaluation unit must be positive-switching, as the
two outputs on the safety switch in the ON state deliver a level of +24 V DC.
12 Commissioning
During commissioning, you must make sure of the following points:
- safety sensor and actuator mounted in the correct position and firmly
- integrity of the power supply lines
