5 Safety regulations and installation notes

• Observe the safety regulations of electrical engineering and industrial safety and liability associations. Disregarding these safety regulations may result in death, serious personal injury or damage to equipment. Power supply units for power supply
• Provide external protection for the input area (A1/A2).
• Make sure that the power supply unit is able to supply four times the nominal current of the external fuse, to ensure that it trips in the event of an error. Startup, mounting, and modifications Startup, mounting, modifications, and upgrades may only be carried out by an electrically skilled person.
• Before working on the device, disconnect the power.
• Carry out wiring according to the application. Refer to the “Application examples” section for this. Reliable operation is only ensured if the device is installed in housing protected from dust and humidity.
• Install the device in housing protected from dust and humidity (min. IP54). In operation During operation, parts of electrical switching devices carry hazardous voltages.
• Protective covers must not be removed when operating electrical switching devices. For emergency stop applications, automatic startup of the machine can pose serious risks for the user.
• The machine must be prevented from restarting automatically by a higher-level controller. With the manual, monitored reset device, a machine start may not be triggered in accordance with EN ISO 13849-1. Inductive loads can lead to welded relay contacts.
• Connect a suitable and effective protective circuit to inductive loads.
• Implement the protective circuit parallel to the load and not parallel to the switch contact. Magnetic fields can influence the device. The magnetic field strength of the environment must not exceed 30 A/m.
• Do not use the device in the vicinity of strong magnetic fields (e.g., caused by transformers or magnetic iron). Noise emission may occur when operating relay modules. Wireless reception may be disrupted in residential areas. The device is a Class A product.
• Observe the requirements for noise emission for electrical and electronic equipment (EN 61000-6-4).
• Implement appropriate precautions against noise emission. Faulty devices The devices may be damaged following an error. Correct operation can no longer be ensured.
• In the event of an error, replace the device. Only the manufacturer or their authorized representative may perform the following activities. Otherwise the warranty is invalidated. – Repairs to the device – Opening the housing Taking out of service and disposal
• Dispose of the device in accordance with environmental regulations. Make sure that the device can never be reused. WARNING: Death, serious personal injury or damage to equipment Depending on the application, incorrect handling of the device may pose serious risks for the user or cause damage to equipment.

6 Function description

6.1 Single-channel sensor circuit

The sensor circuit is not designed with redundancy. The safety relay does not detect short and cross-circuits in the sensor circuit.

6.2 Two-channel sensor circuit

The sensor circuit is designed with redundancy. With the corresponding wiring, the safety relay detects short and cross-circuits in the sensor circuit.

6.3 Automatic start

The device starts automatically after the sensor circuit has been closed.

6.4 Manual, monitored start

When the sensor circuit is closed, the device starts once the start circuit has been closed and opened again by pressing and releasing the reset button. A connected reset button is monitored.

6.5 Safe shutdown

When the sensor circuit opens, the enabling current paths open without delay. When the enabling current paths are open, the device is in the safe state. The signaling current path closes.

Only switch 230 V AC at one of the enable contacts if the adjacent contact carries the same potential. Safe isolation/reinforced insulation (rated surge voltage of 6 kV) Reinforced insulation (e.g., thanks to greater air clearances and creepage distances between conductive paths) is designed for one overvoltage category higher than basic insulation. This means that SELV circuits of U  25 V AC or U  60 V DC and circuits with higher voltages can be mixed.
