2.3 Special types Both the previously named specifications and those in the following apply for special types that are not listed in the type key under point 2.2, provided these agree with the serial design.
2.4 Effects Coded, electronic safety sensor that is activated without touch through a coded actuator. The safety sensor monitors the position of rotating, sliding or also removable protection equipment with the coded electronic actuator. The safety function allows for the safe shut down of the safety outputs when opening the protection equipment and guarantees that safety outputs remain shut down if the protective equipment is opened. As a digital output, the diagnosis output from the safety sensor delivers information about the state of the sensor. This may occur in connection with an SSP safety analysis unit or comparable safety controls. The analysis logics integrated in the sensor as well as an EDM input can use the sensor without additional safety analysis units/controls as well.
The total concept of the control in which the safety component is integrated must be verified according to the relevant standards.
2.5 Series connection The safety sensors permit a series connection with up to 30 sensors upon simultaneously reaching of up to PL e with correct wiring. With a series connection, it must be considered that time delays may add up for each sensor. You can find the corresponding technical data from the table under point 2.9. See point 5.3 for information about the EDM input. You can find wiring examples under point 9.1. Other wiring examples, for example, with our passive distributor XCONN, can be downloaded from our website at www.safety-products.de. The maximum number of safety sensors as well as the total length of the sensor chain are depending on the load. The voltage drop in the system increases with increasing wire length and increasing power load (load + sensors) in the series connection. If the permissible value of 21.6 V is not met, a new feed must be provided.

3. Assembly
3.4 Approach directions
3.1 General assembly notes The requirements of the standard ISO 14119 must be considered during assembly.
Precautionary measures during installation Follow these instructions to avoid injuries or damage to the equipment. The mounting holes permit double-sided assembly options through M4 screws (max. tightening torque 0.7 Nm). Screws made of non-ferromagnetic material (for example, brass) must be used. The mounting position is not important. However, the safety sensor and actuator must be mounted parallel to each other. The safety sensor may only be used in the secured switching distances. The safety sensor and actuator must be permanently mounted to the protection equipment and secured against moving through appropriate measures (usage of non-removable screws, gluing, drilling screw heads, pins). In order to avoid influence caused by the system and a reduction of the switching distances, please observe the following notes: · Metal parts near the sensor may change the switching distance. · Keep metal chips away · Minimum distance between two safety sensors: 150 mm
In order to secure the mounting screws against simple disassembly, we recommend using the screw covers included in the delivery.

3.3 Assembly instruction The safety sensor may only be installed on flat surfaces. · The connection wire from the safety sensor must be laid so that it is protected against
mechanical damage. · Consider the requirements of EN 60204-1, in particular regarding suitable installation,
during assembly. It is recommended to install the sensor wire so that it is covered.
Accessories (to be ordered separately) Set of non-removable screws · SAFIX Z S20: 4 pieces M4x20 incl. washers, SP-K-71-000-00 · SAFIX Z S25: 4 pieces M4x25 incl. washers, SP-K-71-000-01 Seal set · included in the delivery · Plug: 4 units flat for flush closure · for sealing assembly drill holes: Flush non-removable plugs for flat screw heads also suitable for manipulation protection of the screw mounts
Figure 4: Switching distance
Threshold monitoring If the actuator is located in the threshold of the switching distances (see point 2.9 Technical Data) with the corresponding offset values of the sensor, this will be transferred to an SPS or displayed through the LED, see point 6.2. Adjustment The specified switching distances (see point 2.9 Technical Data) only apply to assembly on non-metallic material if the safety sensor and actuator are mounted parallel to each other. Other arrangements may lead to deviating switching distances.

5. Effect and coding
4.1 General notes on the electrical connection The electrical connection may only be executed in a state without voltage and by an authorized expert. The safety outputs may be used directly for the wiring in the safety-relevant part of the user control. For requirements in PL e / category 4 in accordance with ISO 13849-1, the safety outputs from the safety sensor or the sensor chain must be kept at an analysis with the same category.
Both safety outputs must always be evaluated to guarantee safety. Since the diagnosis output is not a safety output, it may not be used for safety-relevant reporting and controlling functions.
4.2 Requirements for the downstream evaluation Two-channel safety input, suitable for p-switching sensors with closer function. Possible analysis units from SSP: · Safety Simplifier · Safety relay series S · Safety relay series E (with EDM function SAFIX _ _-X-_ _) · MOSAIC M1 If the safety sensor is connected with the relay or with unsecured control components, a new risk assessment must be executed. The sensors test their safety outputs through cyclical shut down. A cross-wire monitoring in the analysis is therefore not required. The shut-down times must be tolerated by the analysis. The shut-down time of the safety sensor extends additionally depending on the wire length and the capacity of the wire being used.
4.3 Configuration safety control · Do not use a control with test impulses or turn off the test impulses from your control.
The machine creates it’s own test impulses on the safety outputs. A downstream control must tolerate these test impulses, which may have a length of up to 0,3 ms. Depending on the inertia of the downstream machine (control, relay, etc.), this may lead to short switching processes. · The inputs from a connected analysis device must enable positive switching, because the two outputs of the safety switch delivery a level of +24 V DC when turned on.
5.1 Functioning of the safety outputs The safety sensor has 2 outputs secured against short-circuits (OSSD), which may switch a max. load of 400 mA per channel. The safety outputs connect under the following conditions: · the correct actuator is recognized in the contact area (protection equipment closed) · a high signal is present on both safety inputs · the EDM input is correctly set · no error is detected The safety sensors disconnect under the following conditions: · there is no or an incorrect actuator in the detection area · a low signal is present on one of the two inputs · an error is detected The two safety outputs may be connected to the inputs from a secure control under the following prerequisites: · the input must be suitable for clocked safety signals (OSSD signals); the control must
tolerate test impulses on the input signals (see Technical Data point 2.9). Observe the notes from the control manufacturer. You can find wiring examples under point 9.1.
5.2 Safety inputs The safety sensor has 2 safety inputs. · during the sole usage of the sensor, connect the safety inputs to +24 V DC · when using the sensor in a series connection, the safety inputs from the first sensor are
connected to +24 V DC – the safety inputs from the following sensors are connected with the safety outputs of the previous sensor. Observe also point 4.4. Series Connection for this. – Pulses with a duration of max. 900 s are tolerated on the safety inputs. You can find wiring examples under point 9.1.
5.3 EDM input (External Device Monitoring) The EDM input is included in two different version, once as “automatic”(SAFIX _ _-A-_ _) and once as “monitored”(SAFIX _ _-X-_ _), please consult the type key under point 2.2 for exact descriptions. If the EDM input is not required, the input must be connected to +24 V DC.
EDM input: automatic During protection monitoring, the opener contacts of the protection must be connected to the EDM input. For a series connection with multiple sensors, all EDM inputs must be connected to +24 V DC. The monitoring of the protection must be connected to the last sensor of the chain. You can find wiring examples under point 9.1.
EDM input: monitored (start button) Connect an external start button from your machine control to the EDM input. The EDM input is only detected as correctly set if at least one valid start pules is detected after the sensor is activated and the safety inputs are set. The valid start pulse is detected if a falling flank is detected within the permissible start pulse duration between 30 ms and 5 s following an increasing flank. You can find wiring examples under point 9.1.

7. Commissioning and maintenance
7.1 Functional test The safety switch device must be tested regarding its safety function. The following must be guaranteed in advance: 1. Solid seating of safety sensor and actuator. 2. Solid seating and intactness of the feed. 3. The system is free of all contamination (in particular metal chips).
Note Damaged or defective machines may not be operated!
7.2 Learning process for variation “Individual, retrainable” The first permissible actuator is detected immediately after connecting the voltage supply if it is also located in the detection area of the sensor. All remaining teaching of an actuator must occur as described in the following: 1. Connect supply voltage to the safety sensor. 2. Bring a permissible actuator into the sensor’s detection area. 3. The actuator is recognized, the red LED blinks six times. 4. The LED will begin to flash yellow after 10 s. 5. Turn off the supply voltage within the next 2 minutes. 6. Reconnect supply voltage, then the teaching process is complete and the actuator will
be accepted. 7. If a new actuator is being taught, the safety sensor will block the code of the last
predecessor; this is no longer permissible. 8. Do not remove the actuator during the process as long as it is in the detection area. If the teaching process is canceled, the supply voltage must be turned off and the process restarted. The teaching of actuators on a safety sensor is possible an infinite number of times, provided that the code from the actuator is not blocked in the sensor.
8.1 Maintenance The safety sensor does not require maintenance if it is properly installed and used. We recommend performing a visual and functional inspect in regular intervals with the following steps: 1. Check the safety sensor, actuator an wire for integrity and solid fitting. 2. Remove any metal chips.

8.2 Damaged or defective machines Damaged or defective machines must be replaced with original spare parts! For the “Individual” variation, the safety sensor AND actuator must be replaced. With the “Individually reteachable” variation, the teaching process must be performed during the replacement of the safety sensor OR actuator.
