- 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.
- 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.
- The stated operating distances (see Technical specifications from page 24)
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
- Connect the safety sensor according to the specified wire colors and pin
assignment (see "Circuit diagram and pin assignment" on
page 28).
- 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 it must be noted that the time delay accumulates for
each additional sensor. The relevant technical specifications can be found in
the table from page 24.
Configuration EDM input see point 7.4
Wiring examples can be found on page
. Additional wiring examples, for
example, with T-distributors, can be downloaded from our website http://
www.elobau.com/Machine_safety.
The maximum number of safety sensors, as well as the total length of the sen-
sor chain is load-dependent.
Increasing line length and increasing current load (load + sensors) in the se-
ries connection increases the voltage drop within the system. If the voltage
falls below the permissible value of 21.6 V, a new feed supply must be added.
The elobau T-distributor 350ATD7K can be used for this purpose.
11.2
Information about power supply
- The sensor must be powered directly or indirectly with a SELV/PELV power
supply.
- For use and applications as per the requirements
1)
, the power supply 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 controllers with test pulses or turn off the test pulses in your control
system. The device generates its own test pulses to 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 (control, 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 supply line
We recommend using the screw covers included to secure the
mounting screws against easy disassembly.
The electrical connections must be made without voltage applied
and may be performed by authorized personnel only.
Matching cable sets (type no.: K18G00.K) and an installation
wrench (type no.: MS03) are available directly from Elobau for safe-
ty sensors with connectors. We also offer options for easy wiring in
series connection. T-distributor (Item no.: 350A...K..) and connect-
ing cable (Item no.: K5.G00.K). (For more information see point
13.1 "Accessories" on page 9.)
- 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.
- Also consider the requirements of EN 60204-1, in particular regarding the prop-
er laying of cable. It is recommended to lay the sensor cable so that it is covered.
10 Adjustment
After installation and any fault, a complete check of the safety function must
be performed.
12.1
Teach-in variant "individual"
The first permitted actuator is detected immediately after the supply voltage is
applied, if it is located in the detection range of the sensor.
Each additional teach-in process must be done as described in the following:
1. Apply the supply voltage to the safety sensor
2. Bring an allowable actuator into the detection range of the sensor
3. Actuator is detected, red LED flashes six times.
4. After 10 s the LED switches to yellow flashing.
5. Switch off power supply within the next 2 min.
6. Re-apply power supply, the programming procedure is finished and the
actuator will be accepted.
7. If an actuator is re-taught, the safety sensor disables the code of the
previous process, so this is no longer permitted.
8. Do not remove the actuator during the process, as long as it is located in
the detection area.
If the teach-in procedure is terminated, the supply voltage must be switched
off and the process restarted. The teaching-in of actuators to a security sensor
can be undertaken an unlimited number of times, as long as the code of the
actuator is not locked in the sensor.
13 Maintenance
If the safety sensor correctly installed and used as intended, no maintenance
measures are required.
We recommend periodically carrying out a visual and functional test:
- Check the safety sensor and actuator for tightness.
- Check the connection cable for damage.
Damaged or faulty equipment must be replaced with original
spare parts!
In variant "unique", the safety sensor and actuator must be
replaced.
For the "Individual" variant, a teach-in process must be performed
after replacement of the safety sensor OR the actuator.
