The protective device must be configured, installed, connected, commissioned, and ser‐ viced by qualified safety personnel only. Project planning For project planning, a person is considered competent when he/she has expertise and experience in the selection and use of protective devices on machines and is familiar with the relevant technical rules and national work safety regulations. Mechanical mounting, electrical installation, and commissioning For the task, a person is considered qualified when he/she has the expertise and expe‐ rience in the relevant field and is sufficiently familiar with t ...

The safety relay ReLy HAND1 is an electrical switching device with inputs and outputs. The safety capable inputs of the safety relay are connected to 2 control devices. The control devices control the internal relays, which reliably switch the enabling current paths. The enabling current paths close only when the two control devices are actuated within 0.5 s (concurrence monitoring). Actuators with positively guided contacts are connected to the enabling current paths. 3.2 Product characteristics 3.2.1 Device overview PWR OUT 13 23 I1 Y1 14 24 I2 A2 RELY 1 2 3 4 I3 S1 A1 I4 Figure 1: Device overview 1 ...

DANGER Failure to comply with manufacturer’s obligations Hazard due to lack of effectiveness of the protective device b Carry out a risk assessment before using the safety relay. b Do not manipulate, open or modify the components of the safety relay. b Make sure the safety relay is only repaired by the manufacturer or by someone authorized by the manufacturer. Improper repair can lead to a loss of the protec‐ tive function. 4.2 Operating entity of the machine DANGER Failure to observe operator obligations Hazard due to lack of effectiveness of the protective device b Changes to the machine and chan ...

Required distance: • Above and below the safety relay: ≥ 50 mm • In front of the safety relay: ≥ 25 mm 4.4 Electrical integration Important information DANGER Hazard due to lack of effectiveness of the protective device In the case of non-compliance, it is possible that the dangerous state of the machine may not be stopped or not stopped in a timely manner. b Ensure the safety relay is supplied with supply voltage in all operating statuses. b Ensure that the supply voltage of the safety relay is not connected via safety sen‐ sors or safety switches in order to switch the enabling cur ...

Application diagnostic output Y1 The signal of the Y1 application diagnostic output changes as soon as the enabling cur‐ rent paths switch. The application diagnostic output is not safe.

identify defects as a result of modifications or other influences (e.g., damage or manip‐ ulation). The manufacturer and user must define the type and frequency of the thorough checks on the machine on the basis of the application conditions and the risk assessment. Determination of the thorough checks must be documented in a traceable manner. 4.5.1 Minimum requirements for the regular thorough check The following thorough checks must be carried out at regular intervals: • Thorough check of the housing for damage • Thorough check of the cables for damage • ...

Hazard due to electrical voltage b Make sure that the outputs of the safety relay have no effect on the machine dur‐ ing mounting and electrical installation. b Make sure that the safety relay and the connected components are isolated from all voltage sources during mounting and electrical installation of the device and during mounting/dismantling of the front connector. NOTICE Enclosure rating IP20 only applies if the front connector is mounted. 5.2 Mounting procedure Prerequisites • Mounting is done in accordance with EN 50274 and electrical installation in accordance w ...

1. Press the unlocking mechanism on the upper side of the safety relay towards the back. 2. Loosen safety relay from the mounting rail. 5.4 Device replacement Overview In event of a defect, exchange the device and reuse the front connector with the con‐ nected cables. Approach 1. Disconnect device and the connected components from all voltage sources. 2. Take front connector with connected cables off the defective device: Press the unlocking mechanism of the front connector downwards and pull out the front con‐ nector. 5 MOUNTING 16 O P E R A T I N G I N S T R U C T I O N S | ReLy HAND1 8020872/ZX84/2 ...
