Page 4: General Safety Regulations And Protection Measures
Safety Relay 2. General safety regulations and protection measures • The manufacturer and user of the system/machine on which the protection system is used are responsible for coordinating and adhering to all applicable safety rules and regulations under their own responsibility. • The protection system guarantees functional safety in combination with the superordinate control system, but not the safety of the entire system/machine. Thus, a safety review of the entire system/ machine in accordance with machine directive 2006/42/EC or relevant product standards is necessary prior to use of the device. -

3. General and functi on descripti on The ELMON relay 41-822 (41-322) switching device is used to evaluate sensors such as safety contact mats, safety contact edges and safety bumpers for securing crush and shear locati ons. An ASO sensor can be connected to the switching device. The steady-state current monitoring of the sensor is made possible by an integrated terminati ng resistor in the sensor. Furthermore, the device can also evaluate a sensor in four-wire technology. If the desired steady-state current fl ows, the safety relays are driven and the switching contacts closed. If the sensor is operated or the sensor circuit is interrupted, the relay switching contacts open. -
Page 6: Intended Use
Safety Relay 4. Intended use The switching device can only fulfill its safety-relevant task, if it is used as intended within specifications. The intended use of the switching device is the use as a protection system in connection with safety contact mats, safety bumpers and safety contact edges with 8.2 kΩ resistance for steady-state current monitoring. It is not allowed to use the safety relay in heights over 2000 m above sea level or potentially explosive atmospheres. A different use or any use going beyond the intended use is not within specifications. The manufacturer does not accept any liability for any damage arising from use not within specifications. Any use for special applications requires prior release by the manufacturer. 5. Application example Safety-orientated monitoring of a safety contact edge with start release via release pushbutton and separate continuation of the control circuits (category 3 compliant application according to EN ISO 13849-1). In order to check the functionality of the load breaking K1 and K2 relays the break contacts of these contactors are integrated into the start circuit (Z1 Z2). The signaling relay output is used to visualize the switching state of the safety contact strip. Circuit diagram in voltage-free state.

Page 10: Dip Switch For Configuring The Operating Mode
Safety Relay 6.4 DIP switch for configuring the operating mode „ON“: Automatic reset „OFF“: Fault self-retaining – manual reset (factory setting) „ON“: AUX1 Mode signal output: RLU „OFF“: AUX1 Mode signal output: RL (factory setting) 7. Operating modes 7.1 Safety output Separate or series-connected output of the control circuits (redundant continuation of the switching contacts). In order to use the two safety relays separately, the bridge between 14 and 23 must be removed. 7.2 Automatic reset (S1 = „ON“) After removing a fault in a sensor circuit or after a voltage failure, the switching unit will automatically release output again. Attention: Automatic restart of mashine! If this setting is used, it has to be ensured that no one is able to be in the dangerous zone to avoid hazardous situations. The integrator or operator is responsible for the correct settings of the controller. In no case the manufacturer is liable for incorrect settings or missuse. 7.3 Fault self-retaining – manual reset (S1 = „OFF“) Following removal a fault of in a sensor circuit, or after a voltage failure, the switching unit will only release the output(s) again, if the Z1 and Z2 contacts, 500 ms after the elimination of the disruption, are closed by means of a pushbutton. This completely prevents any automatic re-start. A permanent bridging of the Z1 and Z2 contacts does not cause an automatic reset. 7.4 Signaling output without any delay (RLU) Output (S2 = „ON“) In this mode of operation the corresponding signaling Aux. Relay output is activated without delay, if any fault is signaled on the corresponding channel. The output is always inactive Safety output (symbolic) in the de-energized state of the switching device. -

me lag. Never apply both voltages simultaneously! The 120 V (230 V) supply voltage must be applied to the A1 and A2 terminals. For operati on with 24 V, the supply voltage must be applied to the B1 and B2 terminals. For a fi xed installati on a separati ng device must be available (for example, a main switch for the system). A mains plug is suffi cient as a separati ng device, if it is freely accessible. 9.2 Connecti on of sensor The sensor with a terminati ng resistor of 8.2 kΩ must be connected to the X1 and X2 terminals. The sensor without a terminati ng resistor is connected to the X1 and X2 terminals by means of one lead and with the other lead to the X3 and X4 terminals. 9.3 Connecti on of several sensors per sensor circuit ASO-Sensors must not be connected in parallel. One or several sensors can be connected to the signal transmitt er input. For this purpose, the individual sensors are connected in series in accordance with Figure 1. -

Safety Relay Safety contact edge SENTIR edge: A maximum of 5 SENTIR edge devices can be connected in series. The maximum total length of the SENTIR edge must not exceed 100 m. The length of a SENTIR edge can be up to 25 m. The total line length of the series-connected SENTIR edge must not exceed 25 m. Safety contact bumper SENTIR bumper: A maximum of 5 SENTIR bumper devices can be connected in series. The maximum total length of the SENTIR bumpers must not exceed 15 m. The length of a SENTIR bumper may be up to 3 m. The total line length of the series-connected SENTIR bumpers must not exceed 25 m. Safety contact mat SENTIR mat: A maximum of 10 SENTIR mats can be connected in series. The maximum total surface area must not exceed 10 m2. The size of a SENTIR mat can be up to 1350 x 2350 mm. The total line length of the series-connected SENTIR mat must not exceed 25 m. Before connecting the series-connected sensors, it is recommended to measure the resistance value of the wiring. In the case of non-operated sensors the resistance must be 8.2 kΩ ± 500 Ω. If the sensor is operated, the resistance must not exceed 500 Ω. Sensor „n“ Sensor 1 Sensor 2 Fig. 1: Interconnecting several sensors, here using the example of the safety contact edge 9.4 Connection of control circuits Connect the control circuit to be monitored to the 13 and 24 terminals. If the switching contacts are redundantly continued, the factory-inserted bridge between the 14 and 23 terminals must be removed. In the event of any redundant use of the switching contacts only voltages with the same potential may be connected. The use of different voltage potentials does not correspond to any intended use within specifications. -
