SRBES31 - Lovato - Safety module

<h3>Safety relay for two-hand control</h3><p>This safety relay supervises safety-related control functions in machine panels. In two-hand applications, it helps ensure that the control sequence is managed by the dedicated safety circuit before the hazardous movement is enabled.</p><h4>Technical role and wiring data</h4><p>contacts 3 NO + 1 NC; auxiliary supply 24 VAC/DC; safety category CAT.4; performance level PL e. Selection must follow the contact configuration, actuation type, supply data and the role assigned in the machine sequence. The device should be wired so that command, feedback and safety-related signals remain readable in the electrical diagram and easy to check during maintenance.</p><h4>Commissioning and maintenance</h4><p>During commissioning, test the real operating movement, verify terminal response and compare the result with the machine logic. For replacement, keep the same function, contact layout and actuation principle, then repeat the test before returning the panel or workstation to service.</p><p>The installation should also define how the operator identifies the command state on the panel, machine or workstation. Clear marking, consistent terminal numbering and a documented functional test reduce ambiguity when several similar control devices are installed close to each other.</p><p>During service, compare the installed device with the electrical diagram before changing wiring or replacing parts. The check should cover contact assignment, actuation direction, mechanical return and any accessory used for protection, locking or manual operation.</p><p>The final acceptance check should be made with the actual operator action and with the downstream machine response visible. This confirms that the command element, the wiring and the controlled function remain aligned.</p> <h3>Safety relay for two-hand control</h3><p>This safety relay supervises safety-related control functions in machine panels.
